AI Technical Summary

Technical Problem

In the prior art, when adjusting the head of the flame retardant cable sheath, the extrusion speed and the amount of flame retardant added are difficult to adjust simultaneously, resulting in unstable flame retardant performance of the sheath and even unable to achieve flame retardant effect. Moreover, problems such as cracks, particles and poor toughness may occur on the surface of the sheath.

Method used

By setting up L-shaped mounting blocks, moving plates, loading barrels, cutting pipes, triangle plates, baffles, mounting seats and cutting grooves, the automatic adjustment of the flame retardant cutting frequency is achieved, adapting to the changes in the rotation speed of the screw, and the design of the V-shaped plate avoids the accumulation of flame retardant and ensures uniform cutting.

Benefits of technology

It realizes flexible adjustment of the amount of flame retardant discharge, improves the flame retardant effect of the sheath, makes the surface of the sheath smooth, the finished product of the cable sheath good, the scrap rate is low, and cost savings.

Abstract

The present invention discloses an extrusion device for a flame-retardant cable sheath, comprising a workbench, an extruder housing is fixedly arranged on the top of the workbench, and a screw is rotatably arranged inside the extruder housing. The present invention realizes that the frequency of the V-shaped plate reciprocating with the rotation speed of the screw is driven by the arrangement of an L-shaped mounting block, a movable plate, a charging barrel, a feeding pipe, a triangular plate, a baffle, a mounting seat and a feeding trough, so that the frequency of the flame retardant feeding is adaptively changed, thereby achieving the effect of changing the amount of the flame retardant feeding, and due to the arrangement of the V-shaped plate, the V-shaped plate moves the accumulated flame retardant when reciprocating, forming a long strip and evenly falling into the feeding trough, avoiding the flame retardant from piling up and entering the interior of the extruder housing, ensuring the uniform feeding of the flame retardant, improving the flame retardant effect of the sheath, making the sheath surface smooth, the cable sheath finished product quality is good, the scrap rate is low, and the cost is saved.
