AI Technical Summary

Technical Problem

Existing PVC pipe extrusion equipment has complex coaxiality adjustment when installing the die body and core die, which increases the difficulty and workload of installation and reduces work efficiency.

Method used

A PVC pipe extrusion device was designed. By setting a movable component on the extrusion host, including a movable outer plate, a movable inner plate and a power component, the power component is used to drive the movable outer plate and inner plate to move, which helps to fix the coaxial setting of the core die and the die body, thus simplifying the installation process.

Benefits of technology

The coaxial setting of the core mold rod and the die body is realized, which simplifies the installation operation, reduces complexity and workload, improves work efficiency, and improves the uniformity of melt flow and tube forming quality through the rotation and cleaning functions of the moving components.

Abstract

本申请涉及管材生产加工技术领域,且公开了一种PVC管材加工挤出设备,包括活动外板,所述活动外板设置在分流组件的后方,且活动外板的截面高度与芯模棒外壁与口模体内壁之间的距离相适应,所述活动外板的内部开设有活动槽,且活动外板的活动槽内活动套接有活动内板,所述动力组件的一端固定套接在挤出主机内,且动力组件的另一端穿过分流组件与活动内板固定连接。本发明在安装固定芯模时,利用动力组件推动活动外板和活动内板移动至固定芯模的安装区域,实现对芯模棒的限位,综上,利用活动组件的移动即可保证芯模棒与口模体之间的同轴度,且该操作简单,无需利用外部辅助测量仪器进行,从而降低其安装的复杂性和工作量,提高工作效率。
