Plastic pipe cutting device and method

Abstract

The invention provides a plastic pipe cutting device and method. The plastic pipe cutting device comprises a plastic pipe cooling mechanism and a plastic pipe cutting mechanism. The plastic pipe cooling mechanism comprises a cooling groove (9), and the inlet end of the cooling groove (9) is fixedly connected with a sizing sleeve (22) used for shaping the pipe diameters of plastic pipes. The plastic pipe cutting mechanism comprises a cutter rotary table (23), and the cutter rotary table (23) is fixedly connected with a blade (24). In the plastic pipe cutting operation, the pipe diameters of the plastic pipes are shaped through the sizing sleeve (22) at first after the plastic pipes are formed and extruded, then cooling treatment is conducted through the cooling groove (9), and finally the plastic pipes output by the cooling groove (9) are cut through the blade (24). By means of the plastic pipe cutting device and method, the pipe diameters and pipe bodies of the plastic pipes can be controlled within the set pipe diameter requirement and length requirement range, forming quality of the plastic pipes is greatly improved, and production waste is reduced.

Description

technical field [0001] The invention relates to the technical field of plastic pipe cutting, in particular to a plastic pipe cutting device and a cutting method for continuously cutting plastic pipes. Background technique [0002] At present, when plastic pipes are produced in a production workshop, it is necessary to cut long plastic pipes after thermoplastic molding into plastic pipes of appropriate length. However, due to the plastic raw materials commonly used in the production process of plastic pipes, such as PC materials, after being plasticized at high temperature, they have strong fluidity, so the setting ability is poor, resulting in adhesion and deformation of the produced plastic pipes under high temperature conditions, and After the plastic pipe is cooled, although it becomes hard, it does not meet the requirements of the plastic pipe forming qualification standards due to deformation, etc., resulting in the cut plastic pipe being scrapped due to unqualified qua...

Problems solved by technology

However, due to the plastic raw materials commonly used in the production process of plastic pipes, such as PC materials, after being plasticized at high temperature, they have strong fluidity, so the setting ability is poor, resulting in adhesion and deformation of the produced plastic pipes under high temperature conditions, and After the plastic pipe is cooled, although it becomes hard, it does not meet the requirements of the plastic pipe forming qualification standards due to deformation, etc., resulting in the cut plastic pipe being scrapped due to unqualified quality, and the scrapped plastic pipe cannot be repeatedly processed. Thermoforming, which increases the production costs of plastic pipes
