The front end of the fixing ring 301 at the top and bottom of the processing hole 303 is installed with an electric push rod 305, and a connecting rod 306 is connected to one side of the electric push rod 305. The rear end of the connecting rod 306 at the center position is connected to the cutting knife 308 by a bolt 307, and an adjustment groove 309 is provided at the front end of the fixing ring 301 outside the cutting knife 308.
[0026] Based on the above-mentioned structural setting, the chipless cutting device for plastic pipes is composed of a mounting frame 1, a bearing seat 2 and a cutting mechanism 3, wherein the mounting frame 1 is used to support and protect the cutting mechanism 3, and the bearing seat 2 is used to connect the cutting mechanism 3 and the mounting frame 1. Specifically, during the working process, after the plastic pipe to be cut is inserted into the processing hole 303, the plastic pipe is clamped by the external clamping structure. After clamping, the power mechanism 4 is used to provide power to the cutting mechanism 3. The gear stage 302 drives the fixing ring 301 to rotate inside the bearing seat 2 under the drive of the power mechanism 4, and the electric push rod 3 is started during the rotation. 05. The output end of the electric push rod 305 pulls the connecting rod 306 to move. During the movement of the connecting rod 306, the bolt 307 is used to drive the cutting knife 308 to move, thereby realizing the cutting processing of the plastic pipe. The chip-free cutting device for plastic pipes can achieve cutting processing of plastic pipes of different sizes by adjusting the position of the cutting knife 308.
