In the die-cutting operation and flat knife use, the laminating machine is indispensable. Its main function is to assist the die-cutting host to punch. The material composite before the punching of the die-cutting host and after the punching Waste materials are discharged and used. In the entire assembly line operation, the laminating machine is an indispensable part. So what are the practical skills in the operation of the laminating machine? The following editor will list with you from the following aspects.
　　1, the principle of adjusting the tension of the laminating machine
　　Because of the magnetic powder tension control or mechanical tension control of the laminating machine, the tension is not controlled by a constant tension, so the tension of the rewinding and unwinding needs to be adjusted appropriately with the size of the material roll diameter.
　　①The larger the coil diameter, the greater the tension. When the coil diameter decreases, the tension should be appropriately reduced;
　　②The size of the tension is determined by the material of the product: the tension of the stretchable and easy-to-break material should not be too large, and it must be determined according to the actual situation of the product;
　　③The tension of the rewinding shaft should be greater than the tension of the unwinding shaft, but the tension of the rewinding shaft is affected by the waste and the size of the roll diameter. It should be adjusted appropriately. The larger the roll diameter, the greater the tension;
　　④The lamination tension should not be adjusted excessively, and the principle is to drive the material to feed normally and facilitate the discharge of waste.
　　2. Factors affecting the normal feeding of materials
　　During the operation of the laminating machine, we often encounter phenomena such as material deviation, difficulty in accurate lamination, and misalignment of lamination. So, what are the main reasons for the above problems in materials?
　　①In the bonding seat, the unevenness of the composite pressing roller causes the composite to be inaccurate. The reason is that the unevenness of the composite pressing roller leads to uneven force on the material, which prevents the entire plate from moving forward in parallel;
　　②The suction plate is not opened when the material is being fed, which causes the material to not receive a uniform traction during feeding, which causes the material to be unable to be fed in parallel;
　　③When compounding, the bottom discharge tape and the composite tape are not at the same parallel scale position, causing misalignment;
　　④When compounding, there is a material belt that does not open the tension during unwinding, which causes the material to not be tensioned and causes uneven feeding;
　　⑤ It is caused by not clearly fixing the rewinding and unwinding shaft, the material guide rod, and the limiting device on the feeding plate, resulting in the material being not clearly limited.
　　3. Commonly used waste discharge techniques in laminating machines
　　In the use of laminating machine, waste discharge is one of the important functions, what are the application skills?
　　1. The use of fixtures
　　In the process of waste discharge, due to the particularity of the material, some artificial auxiliary devices are often used to discharge waste, which is what we often call fixtures. Our commonly used treatments include:
　　A. Scraper type tool: mainly used when discharging waste at an angle that is difficult to complete. The scraper fine-tunes the angle of the waste material, so that the material can be separated from the waste material through an angle that is easy to separate;
　　B. Thimble-style tools: mainly use a fixed position, a thimble-style shrapnel formed by a sharp-angled acrylic plate, and use a fixed-position top brush to remove fine-hole waste when passing the material;
　　C. Blow-type tools: mainly by fixing the position of the air pressure pipe, using the blowing method to complete the removal of all-off waste.
　　2. Use of waste disposal angle
The general standard laminating machine is equipped with a large number of movable or fixed guide rods for guiding materials. The main function of the guide rod is to change the angle of the waste discharge belt through different positions of the guide rods between the scraper and the guide rod when discharging waste, and cooperate with the collection of materials. The tension is achieved through the adjustment of the waste discharge angle to complete the smooth waste discharge.
　　3, material belt auxiliary waste discharge
　　A. Add a narrow side auxiliary material belt to the waste discharge belt that is easy to be broken to increase the toughness of the waste belt and facilitate the smooth discharge of waste;
　　B. The release paper is completely broken and discharged. For this kind of product, the opp sealing tape is generally used for composite discharge;
c. Discharge the middle hole position: For products with small holes in the middle of the die-cut product, generally remove the middle hole position release paper first, use masking tape to row the hole position release paper, and then use the acrylic protective film to row the hole positions glue.
　　4. Other functions of laminating machine
　　It is common to use small slitting and installing slitting blade jigs, and use it for micro-classification by feeding.
