Nowadays, PP packing belt production line is used by more and more packaging equipment companies. Its fully automated operation mode and efficient operation system have been praised by everyone. However, with the accumulation and maintenance of working hours, automatic packaging belt production equipment will also be subject to a certain degree of wear and tear. In particular, the screw and barrel of the strap production line are more vulnerable to damage than other components. However, due to the design of the barrel, the service life of the barrel is generally longer than the life of the screw, so the normal wear of the barrel is not required to be repaired with respect to wear of the screw. Then, how can we repair the screw wear of the fully automatic packing belt production line? Then let Kemeijia, which specializes in manufacturing and selling PP/PET bale tape production equipment and PP packing belt, answer your questions!
PP strap production line wear out how to repair
1. If the top surface of the screw thread of the strap production line is worn out, we generally use the method of surfacing special anti-wear and anti-corrosion alloys to repair. The surface of the outer screw (thread top) of the worn strap production line is first ground to a uniform size. The grinding depth is generally 1.7mm, and then the thickness of the alloy layer is built up to a sufficient height to ensure that there is a sufficient machining allowance, leaving at least 3mm. Then grind the outer circle of the screw and the side of the thread. The screw outer diameter is generally larger than the new screw size in order to compensate for the wear of the barrel and maintain the radial clearance of the original design. Local damage to the strapping line can also be used for this method.
2. For the screw of the packing belt production line that originally had a chrome plating layer, after the plating wear, we can re-chrome plating. At present, the metal spraying technology has begun to be applied to the manufacture and repair of strapping wires.
3, strapping production line if the body part of the abnormal damage, such as the occurrence of serious scratches near the end position, can be used to insert the sleeve method, it should be noted that the diameter of the inserted sleeve to fit , and after appropriate surface treatment or lining bimetal lining.
