What Should you Pay Attention to When Operating the Extruder?

What should you pay attention to when operating the extruder?
1. Before starting the extruder, check the inside and outside of the barrel, whether there is any foreign matter in the upper and lower sides of the hopper, check whether the fastening bolts of each part are loose, whether the safety cover is firm, whether the position of each button switch is correct, and then in each lubrication part. Add enough lubricants to clean the equipment.
2. When preparing to turn on the extruder machine, notify the staff around the device.
3. Low-speed starting drive screw rotation motor, check whether the main motor working current meter pointer swing is normal, such as the abnormal operation of the equipment working or the screw running is not stable, stop immediately, find the relevant personnel to repair and solve.
4. The screw running test shall not exceed 3 minutes. After all the normal installation, install the mold and install the connecting bolts for the mold. Before use, apply a layer of molybdenum disulfide or silicone oil for easy disassembly.
5. At the initial stage of feeding, the screw has the lowest working speed, and the feeding is less and uniform. Check whether the operating current meter pointer swing of the motor for driving the screw is abnormal.

6. After the extruder is put into normal production work, the operator should always check the temperature change of the bearing part. When inspecting the temperature of the motor and each bearing part, gently touch the inspection area with the back of the finger. Do not touch any rotating parts with your hands while the equipment is in operation.
7. When disassembling and installing the screw and the mold, it is not allowed to directly hit the parts with the heavy hammer. If necessary, the hardwood should be removed or installed by tapping.
8. When cleaning the residual material on the screw, barrel and mold, it must be cleaned with bamboo or copper knife and brush. It is not allowed to scrape the scrap with steel cutter or use fire to grill the parts.
9. When handling the extruder failure, the extruder is not allowed to drive. When the extruder screw rotates and the mold is adjusted, the operator is not allowed to face the extrusion barrel to prevent accidents.
10. The operator is not allowed to leave the job during the production of the extruder. If it is necessary to leave, the extruder should be stopped.
11. Disassemble the screw after parking, and apply a layer of anti-rust oil after cleaning the residual material. If it is not used for a while, it should be wrapped and hung vertically in a dry and ventilated place.
12. If the extruder and molding die are not used for a long time, the anti-rust oil should be coated and the inlet and outlet holes should be sealed to prevent foreign matter from entering.
