A kind of cutting method of fiber grade polypropylene pipe

Abstract

The invention relates to the field of waste and old fiber grade polypropylene recycling devices, in particular to a fiber grade polypropylene pipe cutting method, the used polypropylene pipe cutting and lifting device includes universal wheels, gantry, limit structure, height adjustment Structure and angle adjustment structure; when the height adjustment structure interferes with the angle adjustment structure, it is convenient to drive the limit structure to reset, which makes the limit structure reset more convenient. At the same time, the limit structure releases the pressure on the height adjustment structure through air pressure, effectively preventing height adjustment The structure impacts the angle adjustment structure. When the height adjustment structure is used, the angle adjustment structure drives the waste winding pipe on the limit structure to rotate, which facilitates the ring cutting of the pipe, reduces the occupied space, and improves the cutting of large pipes. Efficiency and its quality make cutting more secure.

Description

technical field [0001] The invention relates to the field of waste fiber-grade polypropylene recycling devices, in particular to a fiber-grade polypropylene pipe cutting method. Background technique [0002] Polypropylene, a thermoplastic resin obtained by the polymerization of propylene, is used in the production of pipes. With the rapid development of the world plastics industry, a large amount of waste plastics has also been produced, and these waste plastics are still being used in plastic products. For example, in the production process of the coiled pipe, the damaged coiled pipe is often cut and broken again, and then used as the connecting rubber strip of the coiled pipe. [0003] However, when cutting a large waste coiled pipe with a diameter of more than 1 meter, a forklift needs to be used to transport the pipe. During the handling process, the forklift shakes or the pipe is placed in an inaccurate position, which may easily cause the pipe to fall off, and the fork...

AI Technical Summary

Problems solved by technology

[0003] However, when cutting large-scale waste winding pipes with a diameter of more than 1 meter, it is necessary to use a forklift to transport the pipes. During the transportation process, the forklift shakes or the pipes are placed inaccurately, which may easily cause the pipes to fall off, and the forklifts cannot be used in the workshop. The use of aerial cranes with forklifts will affect the normal production of winding pipes during the inspection and maintenance of aerial cranes (24-hour uninterrupted production during the production process of winding pipes, because the equipment warms up for a long time), and after being transported to the designated place, it will be pushed by hand The saw cuts the pipe into shorter sections, and then gradually crushes it through the jaw crusher. During the cutting process, multiple operators are required to push the pipe at the same time to cut the pipe. The cutting efficiency is low, and the operating pressure is high. At the same time, it needs to occupy a large area of ​​the site, which affects the later cleaning, and the safety is low while rolling, which is easy to cause accidents of smashing feet
