Trimming device for solving problem of irregular shape of insulating layer of square tube

Abstract

The invention relates to the technical field of electric power, and discloses a trimming device for solving a problem of an irregular shape of an insulating layer of a square tube. The trimming device comprises a shell, wherein an air ring is fixedly connected to the interior of the shell. Through the combined action of the air ring, a detection mechanism, an insulating tube, a metal slip sheet, an ejector rod, an electromagnet, a brake rod, a first rotary disc and a ratchet wheel, heating operation is automatically triggered by utilizing a bulge on the surface of a cable, so that the bulge of the insulating layer is broken by heating, the trimming operation is facilitated, the trimming operation is started, the linkage between structures is improved, the operation is convenient and fast, and the automation degree is high; and through the combined action of a second rotary disc, a sliding plate, a third rotary disc, a pressing tool and a ring plate, the four faces of the cable are extruded automatically, the other faces of the cable are supported while the insulating layer face where the bulge exists is flattened, the situation that the cable is distorted due to non-uniformity is effectively avoided, and the trimming quality is guaranteed.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a trimming device for solving the problem of non-standard shapes of insulating layers of square cables. Background technique [0002] Cable is one of the common power transmission media. According to the different use environments, a square cable is now introduced. The processing procedure of the square cable is similar to that of the common round cable. Its surface is covered with an insulating layer. The insulation of the square cable The layer needs to be wrapped around the outside of the cable core in a square shape. When the polymer material in the molten state wraps the battery core, there may be air mixed in, which will cause air bubbles to exist on the surface or inside of the insulating layer. When the insulation layer is cooled, the air bubbles will also harden and remain in the insulation layer, making the surface of the insulation layer uneven, reducing the re...

[0002] Cable is one of the common power transmission media. According to the different use environments, a square cable is now introduced. The processing procedure of the square cable is similar to that of the common round cable. Its surface is covered with an insulating layer. The insulation of the square cable The layer needs to be wrapped around the outside of the cable core in a square shape. When the polymer material in the molten state wraps the battery core, there may be air mixed in, which will cause air bubbles to exist on the surface or inside of the insulating layer. When the insulating layer is cooled, the air bubbles will also harden and remain in the insulating layer, making the surface of the insulating layer uneven, reducing the regularity of the cable shape, affecting the normal use of the cable, and not conducive to its installation

[0003] Aiming at the deficiencies of the prior art, the present invention provides a trimming device that solves the problem of non-standard shape of the insulating layer of a square cable, which has the advantages of detecting and automatically trimming the shape of the cable
