Extruder Operating Procedures

① Every time the extruder starts to produce, it is necessary to carefully check whether there are foreign objects in the barrel and up and down the hopper, and remove all debris and oil in time.

② If it is found that the production equipment has abnormal noise or unstable operation, and you are not clear about the cause of the failure, you should stop the machine in time and find relevant personnel to solve it. The equipment is not allowed to be repaired while the equipment is in operation, and the transmission parts are not allowed to be touched by hand.

③ When dismantling and installing the screw and the various parts in the forming die, it is not allowed to hit the parts directly with a heavy hammer.

④ If there is no production material in the barrel, the screw is not allowed to rotate in the barrel for a long time, and the longest idle running time should not exceed 2~3min.

⑤ When there is a failure in the production of the extruder, the operator is not allowed to face the barrel or the mouth of the molding die when troubleshooting, so as to prevent the molten material in the barrel from being ejected and hurting people.

⑥ During the normal production of the extruder, the swing change of the pointer of the ammeter of the main motor should also be frequently observed. When the overloading phenomenon occurs for a long time, it should be stopped in time, and the cause of the fault should be found out and eliminated before continuing to start production.

⑦ When checking the operating temperature of the bearing part and the motor case, lightly touch the detection part with the back of the hand.

⑧ When cleaning the sticky residue on the barrel, screw and mold, it must be cleaned with bamboo or copper knives, and it is not allowed to scrape the material with a steel knife or burn the residue on the parts with fire.

⑨ During the production of the extruder, the operator is not allowed to leave the post to do other work. When he must leave the post, he should stop the car or find someone to take care of it.

⑩ It is not allowed to allow untrained persons to replace formal operators to operate production independently.

⑪ If the cleaned screw is not used temporarily, it should be coated with a layer of anti-rust oil, wrapped, and hung vertically in a dry and ventilated place.

⑫ For extruders that have been out of production for a long time, each working surface of the molding die should be coated with anti-rust oil, and the inlet and outlet ports should be tightly sealed with oil paper. No heavy objects are allowed to be stacked on the barrel and the mold, so as not to be deformed under pressure for a long time.

⑬ All equipment on the production line of the extruder newly put into production should be completely replaced with lubricating oil (grease) in each oil tank and oil cup after 500 hours of commissioning. Bearings, oil cups, oil tanks and oil pipelines should be completely drained of the original lubricating oil and cleaned. Then add enough new lubricating oil (grease)
