Description

Technical Field

[0001] The present application relates to the technical field of pipe cutting, and in particular to a plastic pipe cutting machine. Background Art

[0002] As an important component of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection, low consumption and other advantages. There are mainly UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, polypropylene PPR hot water pipes. Since plastic pipes are generally long, they sometimes need to be cut for use, so a cutting machine is needed to process them.

[0003] For example, a Chinese utility model patent with announcement number CN219968131U discloses a plastic pipe cutting machine, including a cutting table and an adjusting component for adjusting the length of the plastic pipe. A cutting component, a clamping component and two rollers for assisting the movement of the plastic pipe are respectively provided on the top of the cutting table. The clamping component includes a fixed seat, a movable plate, a driving rod and a driving motor. The fixed seat and the driving motor are respectively fixedly installed in the groove on the cutting table. A fixed plate is provided on one side of the fixed seat. The movable plate is movably installed in the slide groove of the fixed seat. An arc-shaped clamping plate extends on the side of the movable plate adjacent to the fixed plate. One end of the driving rod is respectively inserted through the fixed plate and the movable plate, and one end of the driving rod is connected to the output shaft of the driving motor. By arranging a cutting component, an adjusting component for adjusting the length of the plastic pipe, a clamping component and two rollers for assisting the movement of the plastic pipe on the top of the cutting table, the cutting length of the plastic pipe can be conveniently controlled.

[0004] Regarding the above-mentioned related technologies, the inventor believes that when the cutting machine is in use, it can generally only cut one pipe. Processing only one pipe at a time means that the cutting process needs to be carried out one by one, which will reduce production efficiency. Especially when a large number of cuts are required, the time cost will increase significantly.
