Abstract
Description
Technical Field

[0002] Polyethylene is a common plastic material with good toughness and corrosion resistance. Pipe products made by mixing two or more different types of polymers, such as polyethylene, polypropylene, etc. with fillers and heating and molding are called copolymers. Polyethylene composite pipes are composite structure pipes composed of two or more layers of inner and outer polyethylene layers and an intermediate filling layer. Such pipes have good strength, stiffness and corrosion resistance and are widely used in fields such as water supply, drainage, and gas; among them, adding sand or other fillers can improve the compressive capacity and service life of the pipes.
[0003] In order to be able to cut polyethylene composite pipes quickly and accurately, and at the same time ensure the quality and consistency of the cut pipe segments, therefore, a cutting device for the production of polyethylene composite pipes is needed to cut the polyethylene composite pipes. The existing cutting devices for the production of polyethylene composite pipes usually use a clamping device for clamping. During use, since the polyethylene composite pipes are prone to shaking to both sides, when the polyethylene composite pipes are transported to the cutting equipment, the clamping will be unstable. Moreover, the clamping devices of the existing cutting devices for the production of polyethylene composite pipes usually adopt a fixed design, which makes it difficult to adjust the clamping position according to the situation of the polyethylene composite pipes during use, thus reducing the cutting efficiency of the polyethylene composite pipes.
