This article will guide you to the knowledge necessary to operate the machines efficiently. Or you may check the operation manual provided to be familiar with how to operate a sanitary napkin-making machine.
Before you start the machine, make sure you have all of the following items ready:
- Enough raw materials to cover your work area.
- A place to work that is free of dust, debris, and other materials that could interfere with the operation of the machine.
- A spanner to turn around the fiber aggregate saw roller with (if applicable).
- Oil at the greasing points for all moving parts of your machine.
- Check all bolts and nuts for tightness before starting up your machine!
The machine is turned on in the following order:
- The Key on the Control Panel.
- Move the Fiber Aggregate Machine and saw roller (except regular stop).
- Start blowers and vacuum pumps.
- Start bin feeder.
- Start the main motor.
- Start magnetic motor.
Stop the machine in order.
- Shut off the power, heating, and main switches.
- Turn the key to OFF on the control panel. (or close the window text shower) 。 This will allow the saw roller to turn off.
- Wait a few minutes for the machine to cool down before turning off the power switch, heating switch, and main switch.
All the Running Parts Adjustment
When the Fiber Aggregate Machine does not feed smoothly, you may experience several symptoms:
- First, the blowing air valve is likely to be adjusted incorrectly. You should check that the blowing air valve on each side is adjusted correctly to blow air into the pulp. If this is not happening, adjust the blowing air volume on each side glass plate until the forming is well distributed.
- Second, your blower volume may need to be adjusted as well. Adjusting this will help ensure that all your fiber aggregates are correctly fed into the machine.
When the material doesn’t feed smoothly due to the air pressure in the feed bin being higher while the air blower is lower, there are a few ways to resolve this issue:
- First, decrease the material in the feed bin a little bit, and be sure not to decrease it too much. This will allow more material to be introduced into the bin, which will help your machine feed more smoothly.
- Second, clean the rejected bag in the feed bin. This will help remove any impurities or foreign objects that may have become lodged between it and its housing.
- Third, increase the gap of the damper between the body of the bin and the separator slightly. This will allow more flow through this area and reduce any strain due to increased air pressure inside it.
- Fourthly, lower the airflow your feed fan produces slightly to see if there is any impurity on its blades or any blockage formed in your piping system.
The material does not feed smoothly because there is too much cotton pulp stuck on the insert plate of the fiber aggregate machine. This can be caused by static electricity:
- Check to see if there is an excess amount of fiber in the fiber aggregate machine and ensure that there is no lint or debris between the fibers. If this is the case, remove any lint or debris between the fibers with a brush or your hands before feeding the material into the machine again.
The material does not feed smoothly due to the cotton pulp in the suction air catcher. This is caused by the offset of the mesh, which also causes high pressure in the suction air catcher, which creates friction and slows down the feed rate of the material.
- Check if the gap of the aluminum wheel in the Fiber Aggregate Machine has changed and if it’s aligned correctly with its stretch wheel.
- Check if there is a blockage in the mesh; otherwise, check whether any part of your machine is damaged or worn out.
If you are experiencing a problem with your aggregate machine, there are a few things you should check:
- Make sure the topless bar is adjusted to its minimum speed. If it is not, adjust it accordingly.
- Check if the step-less bar is loose.
- Check if the blower is working. If not, ensure it is connected correctly and that you have added air pressure to it appropriately.
- Check if the raw materials feeding is smooth by checking for any clumps or gaps in the material coming into contact with the feeder’s conveyor belt. These can cause problems with your aggregate machine’s performance.
- Check if the feeder’s pressure is enough by checking for leaks at either end of the line. If there are any leaks, ensure that you’ve tightened up those connections so that no more water can escape from them; this will help prevent clogs and decrease pressure on other parts of your aggregate machine as well).
- If there are aluminum wheels on your aggregate machine, but they’re not geared well together—that is, they don’t mesh properly with either of their respective chains—your machine may not be able to produce quality output! Check that they’re meshing correctly by taking them apart and looking closely at how those gears fit together.
Adjusting the pulp feeding blower on the aggregate machine is the first step to solving the pulp feeding problems. Adjusting this device will allow you to increase or decrease the volume of pulp that will be transported to the screen. By adjusting this device, you will also be able to adjust how much pulp is fed into the screen.
If your aggregate machine has been running without problems and then suddenly starts having issues with pulp feeding, there are a few things you can try before calling in an expert:
- Check your side plates on your machine. Oftentimes, these plates need replacing because they are worn out or damaged from years of use. If you find one or more of these plates are not working correctly, replace them immediately!
- If your pulp motor is still functioning correctly but has started clogging up with debris, it may also need to be replaced. If possible, have a professional remove any debris around where it connects to its shaft before replacing it. This should prevent future clogs from occurring if done regularly enough!
Adjustments for Paper Cladding
- Adjust the flaking size of the pulp in the fiber aggregate machine within 135~145;
- Adjust the width of the pulp after cladding by the baffle and the batten on both sides. Keep the pulp going through smoothly, and make sure that the batten should not too tight or too loose.
- Adjust the iron bar on both sides of the paper cladding to wrap the sanitary napkin tightly with the pulp and ensure no loosening.
- Adjust the center distance of the paper cladding to 180mm;
- Adjusting the distance between the sanitary napkin’s freewheel and the cotton pulp’s conveyor wheel allows for no falling or jamming but also avoids falling from a great height or a small height.
Adjustment of Cotton Cutter
- Adjusting the center distance of the cotton cutter to 180mm will help ensure that the cotton pulp goes through the cutter quickly and without any jamming. Before adjusting the cotton cutter, clean all its parts with gasoline to ensure no impurities are present.
To pressure adjust, loosen all bolts on both sides of the cutter and in the center, and tighten the φ12 bolt a little to leave a certain distance between the upper roller and the down roller. If the pulp cannot be cut on one side, just loosen the pressure on the uncut side and tighten the cut side to balance rollers on both sides so that the pulp breaks easily through the cutter.
Inside and Outside Adjustment
Loosen the four bolts on the cutter adapter, and turn the inside and outside adjusting knobs by hand. The cutter body will move outward if you turn the knob clockwise and inward if you turn it counterclockwise. If your X-type cut rejects are more significant than your “normal” cuts (i.e., they have an enormous outside edge), then your cutter should be put in an outward position. Otherwise, reverse the direction of movement so that the inside edge is more significant than the outside edge.
Fore and Aft Adjustment
If the direction of the brake is indicated fore and aft, adjust the position of the cutter through the hand wheel.
Air Volume Adjustment
When cutting wood, it’s essential to ensure that your air supply is adjusted correctly. Air volume adjustment is necessary because it ensures that the wood being cut can be sucked away from the blade by suction. To adjust your air volume, turn the suction air piece when its tightened bolt is loosened. The air should be sucked immediately once the x-type rejects of newly cut are emptied. Then tighten the bolts again. Finally, adjust the distance between the aspiration channel and the cutter to ensure that the X-type rejects can be sucked away smoothly.
Adjustment of Guide Way
Pressure Adjustment To ensure that the material is fed smoothly, we must ensure that the pressure is adjusted uniformly on both sides of the guideway. The procedure for adjusting pressure is the same as what is applied to the cotton cutter. When temperature and pressure meet the requirement, check if the material is fed smoothly.
- If your guideway cannot be pressed up, it is essential to adjust the temperature and pressure to ensure that the machine can be adequately heated.
- To do this, you must adjust the temperature according to the material you are working with. In cases where the pressure is enough while the guideway cannot be pressed up, heat it steps by step until it is pressed up.
- When this doesn’t work, check if there are any impurities or burrs on your guideway and if some electric heating tubes are damaged. If this happens, increase both temperature and pressure accordingly.
Inside and Outside Adjustment
The guideway center distance should be adjusted inward and outward, similar to the cotton cutter. The internal and external adjustment procedures are the same.
Fore and Aft Adjustment
To slow down the speed, use the turning wheel. If there is no brake, use the adjustable flange bolts to loosen the machine housing, turn the guideway to its proper position, and then tighten them again.
Movement type Guide to A or B Product setting
The first step is to adjust the temperature when you want to change from an A-size product to a B-size product.
- To do this, you will need to close your size Cylinder and divide it into “up roller” and “down roller. You will then open your B-size Cylinder and join the “up roller” and “down roller. Next, make sure they connect correctly, adjust the air pressure watch, turn on the temperature switch, and increase the temperature.
Heat Seal Adjustment Model
Pressure Adjustment When the temperature of the hot sealing model reaches a specific value, it needs to be adjusted. The pressure adjustment for the hot sealing model is the same as that of the cotton cutter, which means that both sides must be balanced. When this happens, please pressurize the hot sealing model properly until no crack happens.
Temperature Adjustment The temperature should be adjusted according to the raw material and the required pressure. Heat up the hot sealing model properly when the required pressure is achieved. When the machine is accelerated, increase the temperature for the heat sealing model.
In case the following problems happen during the running of the machine, take relevant measures accordingly:
The top roller cannot be sealed:
- If you look at your own roller, you will notice that it is not aligned with your top roller. This means that there must be a gap between them. If you find an impurity on one of your rollers, you may have to clean them with a cloth and some water. You should also ensure the temperature is proper before starting so the machine can operate smoothly.
One side cannot be sealed:
- To check if the cutter rollers are balanced on both sides, you will need to remove the set of cutters from their housing. You will then see if there is any impurity on either side of the cutter roller. If so, it can be cleaned and reapplied to the cutter roller.
- To check if there is any impurity on either side of the cutter roller, you will need to turn off the machine and remove it from its housing. Once it is removed, check for any impurities that may have been left in or around the cutter roller during manufacturing. If there are any issues with this part, they can be cleaned off and reapplied to ensure they are working correctly.
- To check if there is any impurity on the gear itself, you will need to turn off the machine and remove it from its housing. Once removed, open up the gear housing by removing all eight screws and two tabs on either side of each screw hole (these tabs are located toward one end). Once opened up correctly, you should notice a small black cover over one of these holes.
Inward and Outward Adjustment
- When cutting cotton, it is always essential to ensure that the core is cut at the center. This keeps your paper cladding from becoming uneven and frayed on both sides.
- If you use a hot-sealing model, ensure it is also centered in the machine.
- It’s also essential to ensure that the cotton core is appropriately placed in the middle of 180 MM so it can be evenly distributed on both sides. The adjustment process will vary depending on which model you’re using, but it’s pretty much the same for both types. If there are any unevenness issues during high-speed operation, you can use paper cladding to help out any disparities.
Fore and Aft adjustment
To release the adjustable hand wheel on the brake, rotate the hand wheel in a clockwise direction until it clicks into place. A click will be heard when it moves freely.
If the fore and aft position of your Thermo sealing mold is out of alignment, you should take the following measures:
- Make sure the belt between the cotton cutter and the guideway is not loose. If it is, tighten it.
- Make sure the cotton cutter roller and hot sealing model are not loose. If they are, tighten them.
- Check if there’s any problem with the guideway. If there is, make sure it’s not too hot or that it can’t be pressed up.
- Make sure the chains or synchronous belt in the machine chamber is working correctly.
- Check if the bearings on each driving part are in good condition; if they aren’t, replace them with new ones.
- Ensure all paper cladding around your Thermo sealing mold A or B products is smooth and clean, so it won’t get caught up during production.
- Before you change from one size of Thermo sealing mold A or B product to another, close down your first product’s Thermo sealing mold temperature first; then close down your second product’s Thermo.
- Open B size thermo sealing mold Cylinder, joint “up roller” and “down roller.” Make them connect. Then, adjust the Air-pressure watch, turn on the temperature switch, and increase the temperature. Wait for about 15 minutes until the Thermo sealing mold Cylinder reaches the desired temperature. Turn off the temperature switch, open the Thermo sealing mold Cylinder, and check if there is any leakage or other problems.
Adjustment of Model Cutter
To ensure that the cotton is cut evenly and consistently, we must loosen the four bolts on the cutter adapter. Once the four φ12 bolts are loosened, we can pressurize the roller to get an even cut.
If a partial cut occurs,
- The first thing to check is whether the local blade is in good condition. If not, it needs to be replaced with a new one.
- The second thing to check is whether there is any impurity on the cutter retainer or the blade. If there is, do not use that cutter retainer or that blade again until they are cleaned up.
- The third thing to check is any impurity on the gear. If so, do not use that gear again until it has been cleaned up and checked for impurities.
Inward and Outward Adjustment
- The inward and outward adjustment of the cutter adapter is the same as that of the cotton cutter. If a significant portion is cut inside while a small portion is cut outside due to the machine running at high speed, adjust the driving belt of the suitable side model cutter toward the side which has cut a significant portion. If a small portion is cut inside while a significant portion is cut outside, reverse it.
- To prevent excessive fiber from being pulled out, it is necessary to adjust the hot sealing model according to the distance between the hot sealing model and the cotton core.
Fore and Aft Adjustment
The hand wheel on the brake is supposed to be held in place by two bolts that are easily accessible. Once you have released these bolts, turn the hand wheel back and forth until it is in the proper position. Then tighten the bolts.
In case the fore and aft position is in misalignment:
- If the fore and aft position of the machine is in alignment, check if the driving belt between the hot sealing model and the model cutter is loose. If so, tighten the chain or synchronous belt. Check if any damage has occurred on the bearing, chains, or belt. Check to see if the adjustable hand wheel of the brake is fastened.
Shifting Type, Forming Cutter A or B Products Adjustment
- In this step, we will close the A size forming cutter’s cylinder and divide it into three parts: “up roller,” “down roller,” and “cylinder.” Then, we will open the B size forming cutter’s cylinder, joint “up roller” and “down roller,” and make them connect. Then, we will adjust the air pressure watch to a suitable setting. Finally, we will turn on the temperature switch.
Adjustment of Release Paper
Fore and Aft Adjustment
The adjustable flange bolts are located in the machine housing. Rotate the suction panel to the proper position, and tighten the adjustable flange bolts.
Glue Brake Adjustment
Cut the bolts on the slab rubber. Turn the slab rubber back and forth until the cutter approaches the breakpoint of the glue, then tighten the bolts.
Cutter Breakage Adjustment
If you’re working on a machine with a broken side and the cutter can’t cut through, use a pair of wire cutters to cut through the bolt first. Then, balance the force applied on both sides until the cutter cuts off with a light noise. Once you’ve done this, check the bolts around the bearing to see if they are loose or not.
Inside and Outside Adjustment
Adjust the center distance of the suction panel, then adjust the inside and outside of the release paper. The driving belt of the suction panel can also be used to adjust the inside and outside of the release paper.
Air Volume Adjustment
To ensure that the suction air is directed towards your workpiece, remove the adjustment bolts from the suction air piece. Once this is done, rotate the suction air piece until it is perpendicular to the workpiece. When you cut off your cutter, immediately pull in the air to help keep it in place.
Change A to B size products; the machine has two gears for transmission parts. (A is the same as B).
- Loose A or B’s, tighten the screw of connection gear, and make connection gear and gear separate.
- Takedown A or B connection gear, let connection gear and gear tight, then tidy for the screw of connection gear on tighten seat.
