Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a plastic pipe end cutting device. Background Art

[0002] Plastic pipes are widely used in building water supply and drainage, urban water supply and drainage, gas pipes and other fields due to their advantages of small water flow loss, energy saving, material saving, ecological protection, and convenient completion. Plastic pipes need to be cut at the ends according to needs when in use. The existing plastic pipe cutting device needs to hold the pipe by hand and rotate it to complete the cutting, which makes it inconvenient to operate during cutting.

[0003] To this end, technicians in the relevant technical field have made improvements, such as the "Plastic Pipe Cutting Device" proposed in Chinese Patent Application No. CN201821304263.1. In this application document, two extrusion plates are brought close to each other to clamp the plastic pipe, and the mounting plate is pressed to make the cutting knife close to the pipe and cut it. However, the device cannot process the cut end surface, and the burrs generated by the cutting will affect the subsequent assembly, which requires additional processing steps. To this end, we propose a plastic pipe end cutting device. Utility Model Content
