1. The operator should not stand in front of the machine when operating, so as to avoid accidental injury to the operator. When feeding, prevent the raw material with metal impurities and operating small tools and other hard objects that damage the machine from falling into the barrel. Do not wear gloves when operating rotating machines to prevent injury.
2. Check and increase the lubricating oil in the reducer and air compressor, and check the lubrication of the mechanical transmission parts. Avoid dry operation to damage the machine and make noise.
3. Before starting the operation, check whether the wiring of each power supply is disconnected or leakage; Check whether the instrument is damaged or not. Before starting the machine, ensure the safety and normal of each part, so as not to affect the production and cause accidents.
4. Within the range of film forming conditions, improve the forming temperature, cooling air temperature and blowing expansion ratio; Then the turbidity of the film increases, the gloss decreases; And vice versa.
5. When the discharge from die mouth is uniform, you can wear gloves to slowly pull the tube blank, close the end of the tube blank at the same time, slightly open the air regulating valve, let it put a small amount of compressed air into the center hole of mandrel, and then carefully guide it through the stable bubble frame and herringbone plate, and through the traction roller, guide roller until the coiling (if embossing roller is needed, it should go through embossing roller).
6. The compressed air pressure of the blown billet should be appropriate, which can not break the billet, but also ensure the symmetry and stability of the membrane tube, and relatively ensure the quality of production.
7. When cleaning the extruder and die mouth, copper knife, rod or compressed air can be used to clean it, but avoid damaging the screw and the smooth surface of the screw.
