HF Polyester welder custom.How to repair the worn PP packaging belt of the embossing machine?

　　1. If there is wear on the top surface of the screw thread on the packaging belt production line, we usually use the method of welding special wear-resistant and corrosion-resistant alloys to repair it. Firstly, grind the outer circle (top of thread) surface of the worn packaging belt production line screw to a uniform size. The cutting depth is generally 1.7mm, and the aluminum alloy layer is welded to a sufficient height by electric welding to ensure at least sufficient feed rate. Subsequently, the outer side and outer thread side of the screw are cut, and the diameter of the screw generally exceeds the new screw specification. The purpose is to compensate for the damage to the barrel, maintain the initial axial gap design plan, and apply this method even if the packaging is damaged due to the production line.

　　2. For packaging belts with chrome plating and coating damage, metal material spraying technology has been applied to the production, manufacturing, and maintenance of packaging belts at this stage.
