Equidistant cutting device for waterproof and flame-retardant wire and cable production

Abstract

The invention disclose an equidistant cutting device for waterproof and flame-retardant wire and cable production. The device comprises an operation table, wherein a square groove is formed in the outer wall of the top of the operation table, mounting blocks are fixedly mounted on the inner walls of the two opposite sides of the square groove correspondingly, strip-shaped openings are formed in the outer walls of one sides of the mounting blocks correspondingly, second threaded rods are rotationally connected to the inner walls of the bottoms of the strip-shaped openings by means of bearings correspondingly, limiting rods are fixedly connected to the outer walls of the tops of the second threaded rods correspondingly, first threaded rods are fixedly connected to the outer walls of the tops of the limiting rods correspondingly, second bevel gears are fixed to the ends, extending out of the mounting blocks, of the first threaded rods correspondingly, and the outer walls of one sides of the mounting blocks are fixedly connected with first supports correspondingly. According to the device, a first motor acts, a transmission mechanism drives the first threaded rods and the second threaded rods to rotate, and in a working process, moving directions of an upper cutter and a lower cutter are opposite, so that the upper cutter and the lower cutter get close to each other or get away from each other, and a moving distance of a single cutter in a traditional device is reduced.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to an equidistant cutting device for the production of waterproof and flame-retardant electric wires and cables. Background technique [0002] Since the wires and cables are used for energization, the wires themselves will not be exposed to the outside. In order to ensure the safety of personnel, the wires and cables will be wrapped with insulating materials. An existing waterproof and flame-retardant wire and cable is composed of a tensile core layer, a conductor layer, a functional layer and a protective layer from the inside to the outside, and the functional layer is sequentially composed of a waterproof layer, a flame-retardant layer, a wrapping layer and a polymer layer from the inside to the outside. It is composed of acrylic resin coating, the conductor layer is evenly distributed by a plurality of conductor strips, the space between the conductor strips is provided...

AI Technical Summary

Problems solved by technology

In the prior art, the length of the cable is calculated by means of the storage device. After preliminary processing of the wire and cable, an equidistant cutting device is required to cut the wire and cable. Usually, a hydraulic device is used as a drive to drive the cutter to cut the cable. However, now When some devices are cutting, they only use single-knife pressing down to cut, and the moving distance of cutting is relatively large
