Description

Technical Field

[0001] The utility model relates to a heat shrink tube gluing device, belonging to the technical field of heat shrink tube production. Background Art

[0002] Heat shrink tubing is a very practical insulating and protective material with good insulation performance, excellent sealing performance, high shrinkage rate, and can tightly cover irregular surfaces. In some applications, the inner wall of the heat shrink tubing needs to be coated with glue. After searching, it was found that the Chinese patent with publication number CN218013797U discloses a heat shrink tubing inner wall glue coating machine. In this patent, the heat shrink tubing is first placed in the casing. Pull the slide plate, the spring is stretched, and at the same time, the connecting rod and the splint are driven to move and release the slide plate.
