Assembly line equipment for producing flat PVC heat-shrinkable tube

Abstract

The invention relates to assembly line equipment for producing a flat PVC heat-shrinkable tube. The assembly line equipment is uniform in tube wall thickness, good in shrinkage performance and large in width after folding. The assembly line equipment comprises a mixer used for mixing and stirring PVC main materials and auxiliary materials, a rubber material extruder, a heat-shrinkable tube forming die, various heat preservation and cooling devices and a flat heat-shrinkable tube rolling and packaging device, from the extruder to the rolling and packaging device, a rubber material or rubber tube to be machined moves linearly in a horizontal plane, and the adopted equipment is flat blowing type assembly line production equipment. A plurality of links in the assembly line production equipment for the PVC heat-shrinkable tube are improved, so that the PVC heat-shrinkable tube adopting the assembly line production equipment is uniform in tube wall thickness and better in longitudinal and transverse shrinkage rate, the width of the flat heat-shrinkable tube formed by folding and flatly pressing the heat-shrinkable tube is larger, and the surface of the tube wall of the heat-shrinkable tube is flat, smooth, bright and free of flaws and spots.

Description

technical field [0001] The invention relates to an assembly line equipment for producing PVC heat-shrinkable tubes, in particular to an ultra-thin and large-diameter assembly line equipment for producing flat PVC heat-shrinkable tubes. Background technique [0002] The flat PVC heat-shrinkable tube is packed in a flat shape and occupies a small volume, which is convenient for transportation and reduces transportation costs. It is also flattened when cutting the tube, which is convenient for cutting and improves the quality of the tube. [0003] When the flat PVC heat-shrinkable tube is used, put it on the object that needs to be protected. It has the special function of shrinking when it is heated. It can shrink when heated above 98°C, and it is easy to use. It is used for the outer skin of electrolytic capacitors, inductors, battery cells and battery packs. The product has good high temperature resistance and no secondary shrinkage. [0004] In order to obtain a flat PVC h...

AI Technical Summary

Problems solved by technology

[0004] In order to obtain a flat PVC heat-shrinkable tube with high smoothness, good thermal shrinkage performance and thin tube wall, the formula is complicated, the manufacturing process is difficult, and there are many assembly line equipment processes.

As a result, the production equipment and production processes used by various manufacturers are not the same. Due to the different formulas, processes and equipment, the performance of the products produced is different. Generally speaking, the flat PVC heat shrinkable products currently on the market The tube wall is thick and uneven, making it have low longitudinal shrinkage and transverse shrinkage, causing cracks or wrinkles when the user uses it for the outer packaging of the applied product
