A painting device for polyimide film wound insulated wire and its application

Abstract

The invention discloses a painting device for polyimide film wound insulated wire. The device includes a U-base, the bottom left and right sides of the base are symmetrically connected with a brake universal wheel. The top left and right edges of the base are respectively rotatably connected with a pay-off roller and a guide roller through a fixing frame, an annealing chamber, a painting chamber,a baking chamber and a cooling and lubricating chamber are sequentially arranged between the pay-off roller and the guide roller from left to right, a take-up table is inclined at the top of the right side of the base, and the top of the take-up table is rotatably connected with the take-up roller. The invention can effectively overcome the defects of the prior art that the appearance of the insulated wire is uneven and the feeling of the hand is poor after the traditional polyimide film wrapping the insulated wire painting equipment is processed.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a coating device for polyimide film-wrapped insulated wires. Background technique [0002] The wire or cable includes the bare metal conductor and the insulating layer wrapped around the bare wire. The wrapping of the insulating layer mainly includes the extrusion method of wrapping insulating materials such as PVC and PTFE on the outside of the bare wire by heating and pressurizing the mold. And the winding method in which a strip made of insulating material is wound helically around the bare wire. [0003] The former has high processing cost, complex equipment, and troublesome process, but because the PVC and PTFE particles are directly fused or pressed together with the bare wire by heating and pressurizing, the processed insulating layer has a smooth appearance and a good hand feel. , and it is not easy to have small holes or gaps. The latter has low cost, relative...

Problems solved by technology

[0003] The former has high processing cost, complex equipment, and troublesome process, but because the PVC and PTFE particles are directly fused or pressed together with the bare wire by heating and pressurizing, the processed insulating layer has a smooth appearance and a good hand feel. , and not easy to have small holes or gaps

The latter is low in cost, and the processing technology and equipment are relatively simple, but because the strips are spirally laminated to form an insulating layer, there will be unevenness, poor hand feeling, and there will be gaps to some extent.

[0004] The wires processed by traditional polyimide film-wrapped insulated wire processing equipment cannot completely overcome the shortcomings of uneven appearance and poor hand feeling of film-wrapped insulated wires even after high-temperature fusion and heating and pressure; therefore, it is urgent to design a suitable A paint coating device for polyimide film wrapping insulated wires to change the defects of uneven appearance and poor hand feeling of insulated wires in the prior art
