Environment-friendly inner end surface grinding device for polyethylene pipe

Abstract

The invention provides an environment-friendly inner end surface grinding device of a polyethylene pipe. The device comprises a detachable plate, a polishing assembly and an adsorption assembly, wherein the detachable plate is movably connected below the outer end surface, the polishing assembly is arranged above the interior of the outer end surface, and the adsorption assembly is arranged in themiddle of the interior of the outer end surface. According to the grinding device, a set of first supporting shaft and a set of second supporting shaft are correspondingly arranged on each grinding roller, meanwhile, the outer surfaces of the grinding rollers are uniformly provided with flow guide grooves in a embedding mode, the tail ends of the flow guide grooves are aligned with inclined surface grooves, the tail ends of the flow guide grooves are aligned with the inclined surface grooves, when the flow guide grooves rotate along with the grinding rollers, the gas is driven by the centrifugal force generated by rotation of the grinding rollers to move along the flow guide grooves, and is matched with the inclined surface grooves to enable the flow rate of the gas being larger, furthermore the pipe residue polished by the grinding rollers is moved to the inside of the device, the same non-conductive pipe debris can be further adsorbed, so that the device is more environment-friendlywhen being used.

Description

technical field [0001] The invention relates to the technical field of polyethylene materials, in particular to an environment-friendly grinding device for inner end faces of polyethylene pipes. Background technique [0002] Polyethylene is a thermoplastic resin obtained by polymerization of ethylene. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -100~-70°C), and has good chemical stability. . [0003] Due to the good physical properties of polyethylene, this material is often made into pipe fittings. When using such pipe fittings, it is often necessary to polish and cut them, leaving a lot of pipe fitting residues, and these pipe fitting residues are It is not easy to be decomposed and will cause ecological damage. [0004] Based on the above description, and in combination with the equipment in the prior art, it is found that the existing device cannot collect the residue while gr...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an environment-friendly polyethylene pipe inner end surface grinding device to solve the problem that the existing device cannot collect the residue while grinding, so that a large amount of residue will be left outside, and because the volume of the residue is small, The residue is easy to be blown away by the wind, and it is not easy to gather, and the diameter of the current grinding head cannot be adjusted by itself
