During the production process, the temperature rise of the bearing should be checked frequently. When the temperature rise exceeds 50\u00b0C, the machine should be shut down for inspection to find out the cause and eliminate the fault.2. When the plastic molding machinery is running, the transmission belt is easy to stretch, and attention should be paid to adjusting the proper tightness of the belt to ensure the working life of the belt.3. The wearing parts should be checked frequently and replaced in time to ensure the quality and quantity of the product.4. Always check the wear of blades and bushings. If the productivity decreases after wear and the particle size becomes coarse, the wear is found and replaced.5. The main engine and grading flow bearings are lubricated with grease, using No. 2 special grease, 265-295 degrees.6. The replacement cycle of bearing grease is 2000 hours, and the amount of grease injection is 1\/2 (upper measurement) or 3\/4 (lower measurement) of the bearing cavity space. Do not add too much grease or it will cause the bearing to overheat.7. The plastic injection chiller screw feeder has a grease changing cycle of 4,000 hours, adding ordinary calcium-based grease.
