Connect method of heat-shrinkable sleeve

Abstract

A method for connecting two thermal shrinkage sleeve tubes with each other includes such steps as heating one end of a sleeve tube for shrinking it, inserting it in the end of another sleeve tube, heating the connection position for shrinking it, heating the sealing end of external sleeve tube, and pressing for sealing.

Description

【Technical field】 [0001] The invention relates to the field of heat-shrinkable sleeves, in particular to a connection method for heat-shrinkable sleeves. 【Background technique】 [0002] Heat-shrinkable materials refer to basic materials that are irradiated with high-energy rays and transform linear molecular chains into three-dimensional structures with "shape memory" properties. After heating and expansion, the material will automatically shrink back to its original state after heating, which is heat shrinkage. [0003] Heat-shrinkable sleeves, especially ultra-thin thin tubes, are generally filled with compressed air when the finished product is rolled up and packaged to ensure that it will not be wrinkled and deformed. When more than two sleeves are contained in a minimum package (ie a reel), they must be joined. The current connection methods include lighter sintering method, hot tongs pressing method and knotting method. However, these three methods have disadvantages...

AI Technical Summary

Problems solved by technology

The current connection methods include lighter sintering method, hot tongs pressing method and knotting method. However, these three methods have disadvantages: lighter sintering method has fire hazards, and conflicts with relevant national safety regulations. The clamping method is the same as the clamping method. When the casing is heated and softened, it is often squeezed by the internal compressed air. Although the knotting method is the fastest, it has the highest air leakage rate. Pulling the tube by hand is prone to work-related accidents such as cutting fingers
