Maintenance knowledge of bubble film machines

Maintenance knowledge of bubble film machines
1. Check the power supply, vacuum system, pressure system and cooling system before opening the bubble film machine every time. After starting the equipment, check whether the rotation direction of each rotating component is correct. Pay attention to checking the lubrication condition during normal times. For the lubrication of parts, electrical instruments should be maintained and maintained according to regulations.
2. The bubble film machine equipment should be operated by a dedicated person, and the extruder screw should not idle without material to avoid scratching the screw and barrel. After shutdown, if there are materials in the material barrel, before restarting, it is necessary to raise the temperature of each temperature zone to the specified requirements according to the process requirements, and maintain it for more than 30 minutes before starting the machine. It is strictly prohibited to start the machine before the temperature meets the requirements. To avoid damaging machine parts.
3. When feeding the hopper of the bubble film machine, it is necessary to clean and prevent metal debris, sand, gravel, and small tools from entering the material inlet to avoid damaging the machine barrel and screw. If any abnormal noise is found during operation, the machine should be immediately shut down for handling.
4. The screw is removed from the barrel of the bubble film machine for some reason and should be properly handled to prevent deformation. If the machine barrel is not reinstalled for a long time, the screw needs to be vertically suspended to prevent scratches, bending, and long-term deformation. The surface of the barrel and screw should be coated with anti rust oil for protection.

5. The use, adjustment, maintenance, and upkeep of temperature controllers, electronic instruments, and electrical switches should be carried out in accordance with regulations and product manuals.
6. In addition to daily maintenance, regular inspections of bubble film machine components should also be carried out. The mold head is cleaned every three months, various bearings are replaced with lubricating grease every three months, the gearbox is replaced with lubricating oil every six months, and the equipment is overhauled every two years.
Attention: Before operating the equipment, please carefully read the user manual of the bubble film machine to understand the control and adjustment functions; Stay vigilant and pay attention to safety; Pay attention to safety signs; Wear appropriate goggles; Wear appropriate protective clothing; Use maintenance tools correctly and appropriately; Do not directly come into contact with high-temperature working or heating equipment, and pay attention to the overflow of high-temperature melt; Pay attention to scratches on special parts; Proper maintenance and upkeep of equipment; The wires and power supply parameters used should meet the requirements and it is prohibited to connect the power supply during circuit maintenance; Prohibit limbs from entering equipment transmission and other parts that may cause harm to the human body; After equipment overhaul, the equipment protection facilities should be returned; Before powering on, confirm that the equipment is well grounded.
