Background
The heat-shrinkable sleeve is widely applied to various electronic products, electric power products, new energy sources, medical aspects, medical sheaths and the like, and the main materials of the heat-shrinkable sleeve are plastics, including PE, PVC, EPOM and the like. The expander is used for processing and expanding the heat-shrinkable sleeve to produce products with different diameters.
The existing vacuum adsorption is carried out on the heat-shrinkable sleeve through the vacuum expansion die, so that the outer diameters of the heat-shrinkable sleeve with different multiplying powers are enlarged. However, when the heat-shrinkable sleeve is expanded, the heat-shrinkable sleeve is easy to be stuck on the inner wall of the vacuum expansion die due to higher temperature, so that the friction resistance of the heat-shrinkable sleeve in the vacuum expansion die is larger, the surface of the heat-shrinkable sleeve is possibly wrinkled, and the product quality is affected. It is therefore necessary to design a vacuum dry expander that expands the heat shrink tubing while cooling it down before it sticks to the inner wall of the mold.
