A new heating device for composite pipe reinforcement layer winding

Abstract

This utility model relates to the field of composite pipe processing technology, specifically a novel heating device for winding the reinforcing layer of composite pipes. It includes a heat transfer cylinder and an outer casing. The heat transfer cylinder is covered with high-temperature cotton, and an electromagnetic heating tube is coiled around the outside of the high-temperature cotton. A first assembly plate is fixedly installed at one end of the heat transfer cylinder, and the end of the heat transfer cylinder away from the first assembly plate is sleeved inside an assembly cylinder. A second assembly plate is fixedly installed at one end of the assembly cylinder. The first and second assembly plates each have several assembly holes, and assembly screws pass through these holes. This utility model, through the modular design of the heat transfer cylinder and the assembly cylinder, combined with detachable double assembly plates and screw locking, allows for quick replacement of heating modules to adapt to the production of multi-diameter composite pipes, improving production line flexibility and equipment reuse rate. Furthermore, the electromagnetic heating tube directly heats the heat transfer cylinder using eddy current heating, and the high-temperature cotton blocks heat loss and homogenizes the temperature, achieving efficient, uniform, and directional heating of the winding surface while reducing energy consumption.
