Coating equipment used for cable production and capable of rapidly reducing temperature for reducing bubbles

Abstract

The invention discloses coating equipment used for cable production and capable of rapidly reducing temperature for reducing bubbles. The coating equipment comprises a frame main body, guide rollers,an electric push rod and liquid injection pipes; the guide rollers are arranged at the left end and the right end of the frame main body; the electric push rod is fixed in the upper part of the framemain body; the liquid injection pipes are arranged on the left side and the right side of the electric push rod; a second squeezing plate is fixed at the bottom end of the electric push rod; and connecting ropes are fixed at the left end and the right end of the upper part of the second squeezing plate. The coating equipment used for cable production and capable of rapidly reducing the temperaturefor reducing the bubbles is provided with a first inner air bag and a first outer air bag; the first outer air bag is squeezed by a first squeezing plate, so that gas inside the first outer air bag enters the first inner air bag through a connecting pipe; and the inner side wall of the first inner air bag is in contact with the inner side wall of a coating sleeve ring firstly to close a discharging hole in the inner side wall of the coating sleeve ring, so that raw materials in the coating sleeve ring can be squeezed conveniently, and the bubbles in the raw materials are broken.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to a coating device for cable production that can rapidly cool down and reduce air bubbles. Background technique [0002] 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: [0003] 1. The traditional coating device is to directly spray the coating material on the outer surface of the cable through the coating nozzle. There will be a certain amount of air bubbles between these coating materials, so that when the coating material is coated on ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a coating equipment for cable production that can quickly cool down and reduce air bubbles, so as to solve the problem that the traditional coating device in the market currently contains a certain amount of Bubbles, small contact area during cooling, slow cooling efficiency
