What should we pay attention to when operating the extruder? Jul 19,2019
1. Before starting the extruder, check the inside and outside of the barrel, whether there are foreign objects on the upper and lower sides of the hopper, check whether the fastening bolts of each part are loose, whether the safety cover is firm, and whether each button switch is in the correct position Then in each lubricating section. Add enough lubricant to clean the device.

2. When preparing to turn on the extruder, please inform the people around the equipment.

3. Start the screw rotating motor at low speed and check whether the working motor pointer of the main motor swings normally. If the equipment works abnormally or the screw operation is unstable, please stop immediately and ask relevant personnel for repair.

4. Screw running test shall not exceed 3 minutes. After all normal installations, install the mold and install the mold's attachment bolts. Before use, apply a layer of molybdenum disulfide or silicone oil to facilitate disassembly.

5. In the initial stage, the screw has the lowest working speed, and the feeding times are small and uniform. Check whether the working ammeter pointer of the motor used to drive the screws is abnormal.

6. After normal production of the extruder, the operator should always check the temperature changes of the bearing components. When checking the temperature of the motor and each bearing part, lightly touch the inspection area with the back of your finger. When the device is running, do not touch any rotating parts with your hands.

7. When removing and installing screws and molds, it is not allowed to hit the parts directly with a heavy hammer. If necessary, hardwood should be removed or installed by tapping.

8. When cleaning materials left on screws, barrels and molds, they must be cleaned with a bamboo or copper knife and brush. Do not scrape debris with a steel knife or use fire to burn parts.

9. When handling the extruder failure, do not drive the extruder. When the extruder screw rotates and adjusts the mold, the operator must not face the extruder barrel to avoid accidents.

11. Remove the screws after parking and apply a layer of anti-rust oil after cleaning the remaining material. If it is not used for a period of time, it should be packaged and hung vertically in a dry and ventilated place.

12. If the extruder and molding die are not used for a long time, it should be coated with anti-rust oil, and the inlet and outlet holes should be sealed to prevent foreign matter from entering.
