Description

Technical Field

[0001] The utility model belongs to the field of composite pipe production, in particular to a composite pipe production cutting device. Background Art

[0002] In the production process of composite pipes, a woven metal mesh is wrapped around the outer wall of the tube core, and high-density polyethylene and other materials are coated according to predetermined materials. After the composite pipe passes through a cooling channel, it moves to a feed rack and is supported by the feed rack. After the composite pipe moves to a preset length, the composite pipe is cut by a cutting device. However, the existing composite pipe cutting device requires the composite pipe to stop moving before cutting, which reduces production efficiency. In the prior art, cutting equipment that follows the movement of the corrugated pipe is used in the production and processing of corrugated pipes. However, such equipment generally occupies a large area and is not suitable for composite pipe production lines with shorter production lines and smaller areas. Moreover, compared with the steel belt inside the corrugated pipe, which has greater rigidity and is easy to cut, the inside of the conforming pipe is generally a metal mesh or a plastic steel mesh, which has better flexibility. The structure of cutting corrugated pipes is also not suitable for the cutting process of composite pipes. Utility Model Content
