Description

Technical Field

[0001] The utility model belongs to the technical field of PPH pipe production, and particularly relates to a cutting device for PPH pipes. Background Art

[0002] PPH pipe is a high-performance plastic pipe made of high molecular weight polypropylene using special modification technology. With its excellent corrosion resistance, temperature resistance, mechanical properties and hygiene, it is widely used in chemical, environmental protection, electric power, food, pharmaceutical and other industries, becoming an ideal substitute for traditional metal pipes. The existing PPH pipe cutting device uses a clamping module to drive the clamping block to clamp the PPH pipe, and then the motor drives the cutting knife to rotate and cut the PPH pipe. However, during the cutting process, the rotating cutting knife may cause the PPH pipe to vibrate, which may affect the subsequent processing accuracy.

[0003] For example, the utility model with announcement number CN210061270U discloses a fixed cutting machine for PPH pipe fittings, a chip box is fixed on the top of the workbench, the material pipe passes through the chip box, a chip storage device is symmetrically provided on the top surface of the workbench, table legs are symmetrically fixed on the bottom of the workbench, a placement plate is fixed on one side of the table leg, a support plate is fixedly connected between the placement plate and the table leg, a motor is fixedly connected to the top of the placement plate, a rotating rod is fixedly connected to one end of the motor, and a cutter is rotatably connected to the surface of the rotating rod. In the technical solution of this patent, the PPH pipe to be cut is clamped by a clamping plate, and then the rotating rod is driven by the motor to rotate, so that the cutter on the surface of the rotating rod rotates, and then the PPH pipe is cut. However, in actual use, the PPH pipe is cut by the rotating cutter, and the rotating cutter may cause the PPH pipe to vibrate when it contacts the PPH pipe, causing the PPH pipe to have a slight position shift, which may affect the subsequent processing accuracy.
