AI Technical Summary

Technical Problem

In the continuous production process, existing heat shrink tubing production equipment suffers from localized overheating or cracking due to differences in the uniformity of the heat shrink tubing material and uneven heating, which affects production efficiency and product quality.

Method used

The heating method combines a rotating heating element with a driving element. Hot air is evenly injected through the oblique holes on the rotating heating element, and combined with the air filling inside the heat shrink tubing, dynamic and uniform heating is achieved, avoiding local overheating or rupture.

Benefits of technology

It improves the stability and uniformity of the heat shrink tubing expansion process, reduces the quality risks caused by differences in material uniformity or uneven heating, and significantly improves production efficiency and product quality.

Abstract

This invention relates to the field of heat shrink tubing production equipment technology, and in particular to a continuous heat shrink tubing production equipment, comprising a platform and a tubing rack disposed on the platform for winding heat shrink tubing. One end of the heat shrink tubing is externally connected to an air pump, and the other end is sealed. A heating assembly is used to heat the heat shrink tubing. The heating assembly includes a base disposed on one side of the tubing rack, an inlet and an outlet disposed on the base, a cavity opened in the base, a rotary heating part disposed in the cavity, a drive part connected to the rotary heating part, and an air inlet disposed on the top of the base. By setting up a rotary heating part and a drive part, and utilizing hot air introduced from the air inlet, this invention simultaneously drives the tubing and uniformly heats the heat shrink tubing, effectively avoiding the problem of local overheating or cracking of the heat shrink tubing caused by concentrated heat or uneven heating in traditional heating methods.
