1. Check the dual-screw extruder barrel, the top, and bottom of the hopper, and whether there are foreign objects before starting each time, 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 lubricate each part. Add enough lubricating oil to the parts, and do a good job of cleaning and sanitation of the equipment.
2. When you are ready to drive, notify the staff around the dual-screw extruder equipment.
3. The dual-screw extruder starts the motor for driving the screw rotation at low speed, and checks whether the pointer of the working ammeter of the main motor swings normally. If there is an abnormal sound in the operation of the equipment or the operation of the screw is not stable, it should be stopped immediately, and the relevant personnel should be repaired and solved.
4. The test run of the screw of the twin screw machine should not exceed 30 minutes. After everything is normal, install the mold for production products and install the connecting bolts for the mold. Before use, a layer of molybdenum disulfide or silicone oil should be applied to facilitate disassembly.
5. In the initial stage of feeding and production of the dual-screw extruder, the screw should use the lowest working speed, and the feeding should be small and uniform. Check whether the pointer of the working ammeter of the motor used to drive the screw rotation changes at any time.
6. After the dual-screw extruder is put into normal production, the operator should always check the temperature change of the bearing part. When checking the temperature of the motor and each bearing part, gently touch the inspection part with the back of your finger. Do not touch any rotating parts with your hands during the operation of the equipment.
7. When disassembling and installing the screw and die of the dual-screw extruder, it is not allowed to directly hit the parts with a heavy hammer.
8. When cleaning the residual material on the screw, barrel and mold of the double-screw extruder, it must be cleaned with bamboo or copper knives and brushes. It is not allowed to scrape the residual material with a steel knife or grill the parts with fire.
9. When the double-screw extruder is in trouble, it is not allowed to drive. When the screw is rotated and the mold is adjusted, the operator is not allowed to face the mouth of the extrusion barrel to prevent accidents.
10. The double-screw extruder operator is not allowed to leave the post during production work. If he must leave, the machine should be stopped.
11. Disassemble the screw of the double-screw extruder after parking. After cleaning the residual material, apply a layer of anti-rust oil. If it is not used temporarily, it should be wrapped and hung vertically in a dry and ventilated place.
12. The double-screw extruder and its molding die that have been out of production for a long time should be coated with anti-rust oil and sealed to prevent foreign matter from entering.
