[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-4 This utility model discloses a cutting machine for manufacturing plastic pipes, comprising: a base plate 4, a pipe cutting box 14 fixedly connected to the upper surface of the base plate 4, two through holes 15 provided on the pipe cutting box 14, a sealing collar 16 fixedly connected to the inner wall of the through holes 15, the sealing collar 16 being made of rubber, a perforated plate 17 fixedly connected to the inner surface of the pipe cutting box 14, a dust collection box 10 fixedly connected to the lower surface of the base plate 4, the dust collection box 10 communicating with the pipe cutting box 14, an air pump 18 communicating with the lower surface of the dust collection box 10, a collection box 11 movably connected to the inner surface of the dust collection box 10, and a filter screen 12 penetratingly connected to the bottom of the collection box 11.

[0018] Specifically: During the cutting process, the sealing ring 16 fits against the outer wall of the plastic pipe, preventing plastic debris generated during cutting from escaping through the gap in the through hole 15 to the outside of the pipe cutting box 14. The plastic debris generated during cutting will fall through the mesh of the mesh plate 17 and enter the dust collection box 10. The debris in the dust collection box 10 will fall into the collection box 11. The air pump 18 is started, and under the action of air pressure, the debris enters the pipe cutting box 14 from the outside, then enters the dust collection box 10, and finally enters the air pump 18 for discharge. During this period, the airflow will help the debris in the pipe cutting box 14 to enter the dust collection box 10 and the collection box 11 through the mesh plate 17. Afterwards, the plastic debris is blocked by the filter screen 12 and remains in the collection box 11, realizing the centralized collection of debris for easy subsequent cleaning.

[0019] Rotating sleeves 22 are rotatably connected to both side surfaces of the pipe cutting box 14. During cutting, the rotating sleeves 22 need to be manually rotated. When the rotating sleeves 22 rotate, they will drive the plastic pipe clamped by the fixture inside to rotate, thereby achieving circumferential cutting. A ring track 8 is fixedly connected to the side surface of the pipe cutting box 14. A rotating ring 9 is rotatably connected to the inner surface of the ring track 8. The rotating sleeves 22 are fixedly connected to the front surface of the rotating ring 9. A fixture is provided on both rotating sleeves 22. The fixture includes: a slide rail 19 and a slider 20. The slide rail 19 is fixedly connected to the side surface of the rotating sleeve 22. The slider 20 is slidably connected to the inside of the slide rail 19. The fixture also includes: a clamping plate 23 and a lead screw 21. The clamping plate 23 is fixedly connected to the side surface of the slider 20. The lead screw 21 is threadedly connected to the inner surface of the slide rail 19. The other end of the lead screw 21 is rotatably connected to the side surface of the slider 20.

[0020] Specifically: Insert the plastic tube through the through hole 15 on one side and then through the other through hole 15. By rotating the lead screw 21, the rotation of the lead screw 21 will cause the slider 20 to slide within the slide rail 19. The sliding of the slider 20 will cause the clamping plate 23 to move, thereby bringing the two clamping plates 23 closer together and clamping the plastic tube in the rotating sleeve 22. After the tube is clamped, manually rotate the rotating sleeve 22. The rotating sleeve 22 will rotate smoothly under the constraint of the annular track 8. The rotation of the rotating sleeve 22 will cause the plastic tube clamped by the fixture inside to rotate, preparing for the subsequent circumferential cutting operation.

[0021] The pipe cutting box 14 is provided with a lower cutting edge 13, and a cutting blade 3 is movably connected inside the lower cutting edge 13. A bracket 6 is fixedly connected to the upper surface of the base plate 4, and an electric push rod 5 is fixedly connected to the lower surface of the bracket 6. A lifting plate 1 is fixedly connected to the lower end of the electric push rod 5. A connecting frame 2 is fixedly connected to the lower surface of the lifting plate 1. The cutting blade 3 is rotatably connected to the inner surface of the connecting frame 2. A motor 7 is fixedly connected to the side surface of the connecting frame 2, and the cutting blade 3 is driven by the motor 7.

[0022] Specifically: Activating the electric push rod 5 moves the lifting plate 1. The movement of the lifting plate 1, via the connecting frame 2, causes the cutting blade 3 to move up and down. When cutting is required, the electric push rod 5 extends, allowing the cutting blade 3 to enter the pipe cutting box 14 through the lower cutting edge 13 to cut the pipe. A motor 7 is fixedly connected to the side surface of the connecting frame 2, and the cutting blade 3 is driven by the motor 7. Activating the motor 7 causes the output shaft of the motor 7 to rotate the cutting blade 3 at high speed. After the cutting blade 3 descends into the pipe cutting box 14 and contacts the pipe, the high-speed rotating cutting blade 3 interacts with the rotating pipe, achieving a circumferential cut.

[0023] Working principle: In use, the plastic pipe is inserted through the through hole 15 on one side and then through the other through hole 15. By rotating the lead screw 21, the rotation of the lead screw 21 will drive the slider 20 to slide in the slide rail 19. The sliding of the slider 20 will drive the clamping plate 23 to move, so that the two clamping plates 23 are close to each other, clamping the plastic pipe in the rotating sleeve 22. After the pipe is clamped, the rotating sleeve 22 is manually rotated. The rotating sleeve 22 will rotate smoothly under the constraint of the annular track 8. The rotation of the rotating sleeve 22 will drive the plastic pipe clamped by the clamp inside to rotate, preparing for the subsequent ring cutting operation. Start the electric push rod 5. The electric push rod 5 will drive the lifting plate 1 to move. The movement of the lifting plate 1 will drive the cutting blade 3 to move up and down through the connecting frame 2. When cutting is required, the electric push rod 5 extends, so that the cutting blade 3 enters the pipe cutting box 14 through the lower cutting edge 13 to cut the pipe. The side surface of the connecting frame 2 is fixedly connected to the motor 7, and the cutting blade 3 is driven by the motor 7. When the motor 7 is started, the output shaft of the motor 7 drives the cutting blade 3 to rotate at high speed. After the cutting blade 3 descends into the pipe cutting box 14 and comes into contact with the pipe, the high-speed rotating cutting blade 3 interacts with the rotating pipe to achieve circumferential cutting of the pipe.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
