Plastic pipe cutting device for plastic extruding machine

Abstract

The invention discloses a plastic pipe cutting device for a plastic extruding machine, and relates to the field of cutting devices. The plastic pipe cutting device comprises multiple sets of conveying roller assemblies of the same structure and a cutting device, the multiple sets of conveying roller assemblies are symmetrically distributed on the two sides of the cutting device and used for conveying plastic pipes, and the cutting device comprises a base, a driving assembly, a cutting assembly and a rail assembly; and the conveying roller assemblies and the cutting device are arranged, a first rail and a third rail are symmetrically arranged along the center line of a second rail, a first cutter gradually makes contact with one plastic pipe and cuts the plastic pipe, finally the plastic pipe is cut off through rotation, the first cutter cuts the end of the plastic pipe to expand the inner diameter, and a second cutter cuts the outer wall of the end of the adjacent plastic pipe. The plastic pipe with the two ends easy to connect and free of dislocation is finally obtained, and the problems that the end of an existing plastic pipe is flat, dislocation is likely to happen when a worker winds adhesive tape, the axes of every two adjacent plastic pipes are not coaxial, an included angle is formed, and the adjacent plastic pipes after winding are bent are solved.

Description

technical field [0001] The invention relates to the field of cutting devices, in particular to a cutting device for plastic pipes used in extruders. Background technique [0002] Existing plastic pipes need to be cut into fixed-length plastic pipes after production, and then packaged for delivery. Customers can use tape to wrap multiple plastic pipes according to the length of the pipes, but they find that the ends of the existing plastic pipes are flat. , workers tend to dislocate when winding the tape, and the axes of two adjacent plastic pipes are not coaxial, forming an included angle, which makes the adjacent plastic pipes after winding bend. A plastic tube that will not be misplaced (the inner diameter of one end is enlarged, and the outer diameter of the other end is reduced, so that the plastic tube can be inserted into another adjacent plastic tube. The specific structure is as follows Figure 8 Shown), and research out a kind of equipment that makes this plastic pi...

[0002] Existing plastic pipes need to be cut into fixed-length plastic pipes after production, and then packaged for delivery. Customers can use tape to wrap multiple plastic pipes according to the length of the pipes, but they find that the ends of the existing plastic pipes are flat. , workers tend to dislocate when winding the tape, and the axes of two adjacent plastic pipes are not coaxial, forming an included angle, which makes the adjacent plastic pipes after winding bend. A plastic tube that will not be misplaced (the inner diameter of one end is enlarged, and the outer diameter of the other end is reduced, so that the plastic tube can be inserted into another adjacent plastic tube. The specific structure is as follows Figure 8 shown), and a kind of equipment for making the plastic pipe is developed to solve the above problems for this type of plastic pipe
