Co-extrusion mould capable of replacing identification strip online

Abstract

The invention relates to a co-extrusion mould capable of replacing an identification strip online, and belongs to the technical field of plastic processing. The co-extrusion mould capable of replacing the identification strip online comprises a pipe machine head body, a flow distribution shuttle, an internal mould, a mouth mould assembly, a core mould, an identification strip machine head body and the like; the right end of the pipe machine head body is fixedly connected with the mouth mould assembly; the flow distribution shuttle and the internal mould are mounted in the cavity of the mouth mould assembly in sequence from left to right; the right end of the internal mould is fixedly connected with the core mould; an identification strip rib plate (a) and an identification strip rib plate (b) of different types are embedded into the mouth mould assembly; a connecting nozzle (a) with a check valve (a) and a connecting nozzle (b) with a check valve (b) are mounted at the upper part of the mouth mould assembly; the identification machine head body is mounted at the upper parts of the connecting nozzle (a) and the connecting nozzle (b). According to the co-extrusion mould capable of replacing the identification strip online, the types of pipe identification strips can be replaced online by only opening and closing the check valves; moreover, the structure is simple; the operation is convenient; compared with original artificial mould removal, the rejection rate is reduced by 80 percent; the labour intensity is low; the production efficiency is high. The existing problems of waste of time and artificial energy consumption caused by stopping a machine and removing the mould when the identification strip is replaced are effectively solved.

Description

technical field [0001] The invention relates to a co-extrusion mold capable of replacing identification strips on-line, belonging to the technical field of plastic processing. Background technique [0002] HDPE silicon core tube is mainly used as the outer protection tube of optical cable, and it is widely used in the field of communication. In the laying process of silicon core pipes, due to the large number of pipes laid together and the long path, in order to distinguish the pipes, silicon core pipes with different types of identification strips are combined and laid, so we need to produce a variety of different identification Strips of silicon core tubes to meet the needs. Considering actual production, it is impossible for us to purchase a large number of production equipment to ensure that one piece of equipment is fixed to produce a kind of identification strip pipe, so in production, we need to replace the identification strip parts on the machine to replace the ide...

AI Technical Summary

Problems solved by technology

In the traditional process of replacing the identification strip, we need to stop the machine and manually remove the mold for replacement. It takes at least an hour to replace the identification strip from shutdown to normal production again. The labor intensity of the employees increases, and there are many waste products, which is wasted. Labor and energy consumption lead to higher production costs and lower production efficiency of silicon core tubes
