Coating control method for cable production

Abstract

The invention discloses a coating control method for cable production. The control method is realized on the basis of coating equipment. The coating equipment comprises a frame body, guide rollers, electric push rods and liquid injection pipes, wherein the guide rollers are arranged at the left end and the right end of the frame body correspondingly, the electric push rods are fixed in the upper portion of the frame body, the liquid injection pipes are arranged on the left sides and the right sides of the electric push rods correspondingly, and second extrusion plates are fixed to the bottom ends of the electric push rods. The coating equipment capable of quickly cooling and reducing bubbles for cable production is provided with the first inner air bag and the first outer air bag; the first outer air bag is extruded through the first extrusion plate; the first outer air bag is arranged, so that air in the first outer air bag enters the first inner air bag through the connecting pipe, the inner side wall of the first inner air bag is in contact with the inner side wall of the coating lantern ring firstly, a discharging hole in the inner side wall of the coating lantern ring is closed, raw materials in the coating lantern ring can be extruded conveniently, and bubbles in the raw materials are broken.

Description

[0001] This application is a divisional application of a Chinese invention patent application with the application number 201910805275.5 filed on August 29, 2019, and the title of the invention is a coating equipment for cable production that can rapidly cool down and reduce air bubbles. technical field [0002] The invention relates to the technical field of cable production, in particular to a coating control method for cable production. Background technique [0003] As the name implies, cable production refers to the collective name of a series of activities involved in the production process of cables. During the production process, the outer surface of the cable will be coated with insulating paint or asphalt to protect the surface of the cable. Therefore, the cable will be used during production. As far as the coating device is concerned, although there are many types of coating devices on the market, there are still some shortcomings, such as: [0004] 1. The traditio...
