Description

Technical Field

[0001] The utility model relates to the technical field of wire harness heat shrink tubing, in particular to a heat shrink tubing baking and shrinking device. Background Art

[0002] Heat shrink tubing is a special polyolefin heat shrink tubing, usually made of EVA material, with high-temperature shrinkage, soft flame retardancy, insulation and corrosion resistance. Heat shrink tubing is widely used for insulation protection of various wire harnesses, solder joints, inductors, and rust and corrosion protection of metal tubes and rods. Currently, heat shrink tubing is widely used in the production process of wire harnesses to achieve insulation and corrosion protection at the connection points of the wire harnesses. During the production process, workers usually put a section of heat shrink tubing on the connection points of the wire harnesses for operation. However, the heat shrink process has the following disadvantages:

[0003] 1. Originally, the wiring harness with heat shrink tubing was manually moved to a hot air blower, where the hot air was used to heat the heat shrink tubing to shrink it. Manual operation would be quite hot and could easily burn your hands.

[0004] 2. Because the position of the heat shrink tube is relatively high, it needs to be positioned manually during heat shrinkage, so only one position of the heat shrink tube can be baked at a time, which is inefficient;
