AI Technical Summary

Technical Problem

In existing high-density polyethylene pipe splicing devices, molten plastic residue and impurities easily adhere to the surface of the heating plate during long-term hot-melt processing, resulting in uneven heating, reduced thermal conductivity, affecting the hot-melt quality and increasing the difficulty of operation.

Method used

A high-density polyethylene pipe splicing device was designed. A scraper is used to remove molten residue from the surface of the heating plate. An elastic scraper is used in conjunction with a suction machine to adsorb impurities. The active roller and auxiliary roller are used to clamp the pipe to ensure the stability of the pipe position. The contact sleeve scrapes impurities from the outer wall of the pipe and collects waste materials in a unified manner.

Benefits of technology

It effectively removes residue from the surface of the heating plate, ensures the quality of heat fusion, prevents damage to the heating plate, improves operating efficiency, ensures the stability and cleanliness of pipe splicing, and reduces the risk of waste splashing.

Abstract

The invention relates to the technical field of pipe fitting and pipe splicing, and particularly discloses a high-density polyethylene pipe fitting and pipe splicing device.A second transmission component is fixedly connected to the middle of a workbench, a hot melting component is slidably connected to the middle of the top of the workbench, and a positioning frame is arranged in an inner cylinder in a cross shape; a positioning shaft is slidably connected to the side face of the positioning frame, a positioning block is fixedly connected to the other end of the positioning shaft, and a rotating block is rotatably connected to the inner side of the positioning block. According to the high-density polyethylene pipe fitting and pipe splicing device, a scraper can remove molten residues and plastic impurities attached to the surface of the heating plate, high-temperature carbonization and scaling of materials are avoided, elastic self-adaptive attachment is achieved through sliding fit of a connecting rod and a second spring, the attachment plate face guarantees the residue removal effect, the scraper is prevented from rigidly scraping and damaging the plate face, and the service life of the scraper is prolonged. And meanwhile, scraped chippings and residues are adsorbed in real time, and waste is prevented from splashing and scattering.
