TPU welding machine Production.Standard Operation and Precautions for Packaging Belt Production Line

　　1. Preparation before starting the packaging belt production line

　　Firstly, we need to check whether the equipment and packaging belt are inserted correctly. Secondly, we need to check whether the power wire is damaged. Secondly, we need to check whether all moving parts are lubricated. Furthermore, we need to check whether the packaging belt production line is fixed and not moving. Prepare a checklist before starting the machine and perform routine checks.

　　2. Standardized operation of packaging belt production line

　　The operator of the packaging belt machine should have a basic understanding of the structure, working principles, operating procedures, and adjustment methods of the packaging belt machine. Before operation, the power should be turned on, and the packaging belt machine should be preheated for a few minutes. At the same time, the length of the packaging belt should be adjusted, and of course, the packaging belt machine should also be listened to for any noise.

　　3. The operation of the packaging belt production line is completed

　　After operating the packaging belt machine, remember to cut off the power supply and turn off the switch to prevent leakage and electric shock.

　　Another special reminder is that it is strictly prohibited to put your hands into the packaging belt, and dangerous actions such as disassembling and disassembling equipment during operation are strictly prohibited.

　　1. The temperature control of the packaging belt production line barrel should gradually increase from the feeding section to the homogenization section. The mold temperature should be equal to or slightly lower than the maximum temperature of the packaging belt mechanical barrel.

　　2. When extruding and plasticizing the raw materials of the packaging belt, a porous plate and filter screen should be added in front of the machine. The number of mesh and layers of the screen should be determined based on the working conditions of the raw materials and belt; The number of mesh should be greater than 80.

　　3. The strip blank of the packaging belt production line should be perpendicular to the water surface and enter the water tank. If the strip blank is too wide, the distance from the mold to the liquid level should be appropriately increased or the speed of the traction stretching roller should be increased; If the width and size of the strip blank are insufficient, the distance from the mold to the liquid level should be reduced or the speed of the traction stretching roller should be appropriately reduced. If necessary, the extrusion amount of the melt can also be adjusted by adjusting the screw speed to adjust the width of the belt.
