On-line continuous injection molding equipment for power cable pipes

Abstract

The invention discloses an on-line continuous injection molding equipment for a power cable tube, comprising a conveying mechanism, one end of the conveying mechanism is provided with a cutting mechanism and a material turning mechanism, the material turning mechanism is located outside the cutting mechanism, and the other end of the conveying mechanism is provided with a cooling mechanism, the cooling mechanism The outer end is provided with a moving mechanism, the top of the moving mechanism is installed with a curing molding device, and the front side of the moving mechanism is provided with a glue injection mechanism; after adopting the above structure, in the entire closed environment, using appropriate injection pressure, from the surrounding of the pipe to the pipe. Glue injection infiltration ensures uniform infiltration of fibers and glue, and at the same time avoids any irritating gas and air pollution.

Description

technical field [0001] The invention relates to the technical field of preparation of power cable tubes, in particular to an on-line continuous injection molding equipment for power cable tubes. Background technique [0002] In today's society, with the rapid development of industry, the importance of pipelines has become increasingly prominent, ranging from South-to-North Water Diversion to small tooling lines and pipes. These pipes are developing rapidly in a variety of ways. The overall analysis of the types of pipe materials includes conventional PE, PVC, PPR, conventional plastic modification, alloy materials and composite materials, etc., which are some of the better liquidity in the market. pipeline. [0003] At present, a continuous glass fiber braided and wound pultruded tube of unsaturated polyester resin is circulating on the market. Its structure is mainly an inner lining layer, a middle lining layer, and an outer lining layer. bonding. This three-layer struct...

Problems solved by technology

However, due to the actual operation of the formulation system of unsaturated polyester resin, a large amount of irritating gas will be generated, which will have a great impact on the on-site operators and the surrounding environment; at the same time, the mainstream unsaturated polyester resin continuous glass fiber braided winding The pultrusion tube is exposed to the air during glue spraying, and it is naturally dipped in glue without pressure

As a result, the glue cannot completely and evenly penetrate into the pre-woven fibers of the pipe, and eventually the glue in some parts of the pipe is missing or not full during curing, so that the pipe has water seepage after curing or the performance of stretching and ring rigidity is reduced.
