[0002] Plastic pipes are generally made of synthetic resin, that is, polyester as raw material, with the addition of stabilizers, lubricants, plasticizers, etc., and are made by extrusion in a pipe making machine using the "plastic" method. In the process of producing plastic pipes, the plastic pipes need to be cut. When cutting plastic pipes, a plastic pipe production fixed-length cutting device is required.

[0003] In the prior art, there are the following problems:

[0004] Usually, when cutting plastic pipes in production, the plastic pipes are mostly introduced into the cutting device, the baffle is used to support one end of the plastic pipe, and the cutting knife on the cutting device is used to cut the plastic pipe to a fixed length. The existing solution is to drive the baffle to move and adjust the distance between the baffle and the cutting knife, so as to adjust the length of the fixed-length cutting. However, the existing cutting device has a long length, and the cutting device needs to occupy a large space when in use or transport. When adjusting the length of the fixed-length cutting, it is not convenient to drive the length of the entire device to be telescopically adjusted, which brings more inconvenience to use. At the same time, most traditional plastic pipe cutting methods are to use a cutting knife to extrude and cut the plastic pipe. When the cutting knife extrude and cuts the plastic pipe, it is easy to cause the plastic pipe to sag and deform. Utility Model Content
