A device for peeling the end of plastic pipe fittings

Abstract

The invention discloses a peeling device for the end of a plastic pipe fitting, which comprises: a box body, a cylindrical slot is opened on the side of the box body; a peeling knife assembly, the skinning knife assembly is fixedly installed inside the slot; an inner tube A support assembly, the inner tube support assembly includes a mounting column, a supporting blade and a supporting rod, the mounting column is fixedly installed on the rotating end of the peeling knife assembly, and a sliding groove is opened on the surface, and one end of a plurality of the supporting blades is rotatably connected to the A plurality of sliding grooves away from one end of the peeling knife assembly; a limit assembly; a rotation adjustment assembly, the rotation adjustment assembly includes a moving block and a resisting block, and one end of the moving block is fixedly installed on the end of the limit assembly away from the support rod, and another One end is an inclined edge, and the said block is fixedly connected to the peeling knife assembly. The invention can perform peeling processing on plastic pipes with different diameters, and internally support the peeling position, thereby avoiding deformation of the plastic pipes and ensuring the peeling effect of the ends of the plastic pipes.

Description

technical field [0001] The invention relates to the technical field of plastic pipe processing, in particular to a device for peeling plastic pipe ends. Background technique [0002] PPR is the abbreviation of three-type polypropylene, also known as random copolymer polypropylene pipe. In order to strengthen the outer protection of PPR, aluminum film or oxygen barrier layer is usually processed on the outside of the pipe body, and ppr pipe connection is generally adopted by hot-melt welding , in order to achieve hot-melt welding, the aluminum skin or oxygen barrier layer on the surface must be removed, so as to facilitate the hot-melt processing of the pipe. [0003] When the peeling knife peels the plastic tube, the knife body and the plastic tube are squeezed, and the outer wall of the plastic tube is removed by the blade. However, due to the elasticity of the plastic tube, the plastic tube will break under the extrusion of the blade. Deformation, resulting in uneven peel...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art. Because the plastic tube has elasticity, the plastic tube will be deformed under the extrusion of the blade, resulting in uneven peeling of the plastic tube by the rotating blade, which is easy to After the hot melt welding is affected, a device for peeling the end of plastic pipe fittings is proposed
