1. each extruder before driving to check the barrel, the hopper up and down and inside for the presence of foreign objects, check whether the fastening bolts in various parts are loose, the safety cover is firm, the position of the button switch is correct, and then in the lubrication parts Add enough lubricants to clean the equipment.

2. When preparing to drive, notify the staff around the equipment.

3. low speed start to drive the extruder screw barrel rotating motor, check the main motor operating current meter pointer swing is normal, if there is abnormal operation sound of equipment or screw operation is not stable, should immediately stop and find the relevant personnel maintenance solution.

4. screw air test run is not allowed more than 3min, after all normal installation of production products with the mold, install the mold with the connection bolts, should be coated with a layer of molybdenum disulfide or silicone oil before use, to facilitate the removal.

5. In the initial stage of material production, the screw uses a minimum working speed, and the material is small and uniform. At any time, check whether there is any abnormality in the swing of the working current meter pointer of the motor used to rotate the drive screw.

6. After the extruder is put into normal production work, the operator should always check the temperature change of the bearing part. When checking the temperature of the motor and bearing parts, apply finger back to gently touch the inspection site. Do not touch any rotating parts with your hands during operation.

7. When disassembling and installing the screw and die, do not hit the part directly with a heavy hammer. If necessary, pad hardwood and then knock or disassemble.

8. When cleaning the screw, barrel, and mold residue, use a bamboo or brass knife or brush to clean it. Do not use steel tools to scrape the residue or use fire to grill the parts.

9. When handling extruder failures, the extruder is not allowed to drive. When the extruder screw rotates and adjusts the mold, the operator must not face the extrusion cylinder to prevent accidents.

10. When the extruder is in production, the operator is not allowed to leave the post. If it is necessary to leave, the extruder should be stopped.

11. Remove the screw after parking. After the residue is cleaned on the net, apply a layer of anti-rust oil. If it is not used for the time being, it should be properly wrapped and hung vertically in a dry and ventilated place.

12. The extruders and molding dies that are not used for a long period of time shall be coated with anti-rust oil, and the access holes shall be sealed to prevent entry of foreign matter.
