Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wire harness heat shrinkage, specifically to a wire harness heat shrinkage drying tube machine. BACKGROUND

[0002] The wire harness drying tube machine is a device for heating and curing the insulation layer of the wire harness, and is widely used in the wire and cable manufacturing industry. The heat shrink tube provided on the outer wall of the wire harness is heated by the heat shrink machine, so that the heat shrink tube shrinks under heat, wraps and adheres to the outer wall of the wire harness, and plays a protective role.

[0003] The heat shrink tube is a specially made polyolefin material heat shrink sleeve. The outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation and corrosion resistance, wear resistance, etc. The inner layer has the advantages of low melting point, waterproof sealing and high adhesion. The heat shrink tube has excellent flame retardant and insulating properties, is very soft and elastic, has a low shrinkage temperature, and can be widely used in wire harness connection protection, wire harness identification, and insulation protection of resistors and capacitors.

[0004] In the prior art, for example, a Chinese patent with the authorization announcement number CN216330103U and the name of a heat shrink machine for wire harness, the above-mentioned patent discloses a heat shrink machine for wire harness, which belongs to the technical field of heat shrink machines and comprises a heat shrink machine body. The heat shrink machine body is provided with a hot air blower inside, and a heat shrink groove is formed at the top of the heat shrink machine body. First and second mounting seats are symmetrically arranged on the outer side wall of the heat shrink machine body. Motors are arranged on the top of the first and second mounting seats. The power output ends of the motors are respectively opposite to the heat shrink machine body in the horizontal direction, and the power output ends of the motors are both transmissionally connected with a disc, and the connection is at the center of the disc. The outer side wall away from the power output end of the motor is fixedly connected with a linkage rod.
