[0027] In one embodiment, support rods 101 are fixedly installed at all four ends of the surface of the base 1.

[0028] Specifically: The support rods 101 support and fix the fixed clamping plate 201.

[0029] In one embodiment, the clamping device 2 includes a fixed clamping plate 201. The four ends of the bottom of the fixed clamping plate 201 are respectively fixedly installed at the tops of four support rods 101. Four limit slide rods 202 are fixedly installed at the four ends of the top of the fixed clamping plate 201. Limit plates 203 are fixedly installed at the tops of the four limit slide rods 202. A stepper motor 204 is fixedly installed at the bottom of one side of the fixed clamping plate 201. The output end of the stepper motor 204 is installed with a threaded rod 205 through the surface of the fixed clamping plate 201 via a bearing.

[0030] Specifically: The limit slide rods 202 and the limit plates 203 limit the movement of the moving clamping plate 3. The stepper motor 204 drives the moving clamping plate 3 to move up and down through the threaded rod 205 and the mounting seat 301.

[0031] In one embodiment, the four ends of the moving clamping plate 3 are movably sleeved on the surfaces of the four limit slide rods 202. A mounting seat 301 is fixedly installed on one side of the moving clamping plate 3. The mounting seat 301 is threadedly sleeved on the surface of the threaded rod 205.

[0032] Specifically: The moving clamping plate 3 is threadedly connected to the threaded rod 205 through the mounting seat 301 and can move up and down with the rotation of the stepper motor 204.

[0033] In one embodiment, the cutter assembly 4 includes a connecting ring 401. One side of the connecting ring 401 is fixedly connected to one side of the fixed clamping plate 201. A rotating sleeve 402 is sleeved on the surface of the connecting ring 401 via a bearing. A toothed ring 403 is fixedly sleeved on one side of the surface of the rotating sleeve 402. A mounting rod 404 is fixedly installed on one side of the rotating sleeve 402. A blade 405 is sleeved on the surface of the mounting rod 404 via a bearing. An activity groove 406 is opened on one side of the blade 405.

[0034] Specifically: One side of the moving clamping plate 3 does not contact the connecting ring 401, and the connecting ring 401 does not affect the up and down movement of the moving clamping plate 3; the connecting ring 401 is fixedly connected to the fixed clamping plate 201, the rotating sleeve 402 rotates movably on the surface of the connecting ring 401 via a bearing, the mounting rod 404 supports and fixes the blade 405, and the activity groove 406 mounts and moves the ejector rod 504.

[0035] In one embodiment, the cutting drive assembly 5 includes an L-shaped mounting base 501. The bottom of the L-shaped mounting base 501 is fixedly mounted on the surface of the rotating sleeve 402. A hydraulic telescopic rod 502 is fixedly mounted on the top of the L-shaped mounting base 501. The output end of the hydraulic telescopic rod 502 is mounted with a connecting plate 503 through the surface of the L-shaped mounting base 501 via a bearing. A push rod 504 is fixedly mounted on one side of the connecting plate 503. The surface of the push rod 504 is movably disposed inside the movable slot 406.

[0036] Specifically: A limiting ring is connected to one end of the push rod 504 away from the connecting plate 503 to limit the push rod 504 and prevent the push rod 504 from disengaging from the inside of the movable slot 406. The L-shaped mounting base 501 serves to mount and fix the hydraulic telescopic rod 502. The hydraulic telescopic rod 502 pushes the blade 405 to move through the connecting plate 503 and the push rod 504. The movable slot 406 has a certain length of space. When the connecting plate 503 moves downward to push the blade 405 to rotate about the mounting rod 404 and move downward at one end for cutting, it provides a moving space for the push rod 504. When the push rod 504 drives the blade 405 to move, it moves inside the movable slot 406.

[0037] In one embodiment, the driving device 6 includes a mounting plate 601. The top of the mounting plate 601 is fixedly mounted on the bottom of the fixed clamping plate 201. A servo motor 602 is fixedly mounted on one side of the mounting plate 601. The output end of the servo motor 602 is fixedly mounted with a gear 603. The gear 603 meshes with the toothed ring 403.

[0039] Working principle: When using this device to cut a PE pipe, first pass the PE pipe through the connecting ring 401 and place it on the surface of the fixed clamping plate 201, so that the position to be cut is aligned under the blade 405, and then start the stepper motor 204 through the external controller. After the stepper motor 204 is started, it drives the threaded rod 205 to rotate, and drives the movable clamping plate 3 to move downward through the mounting seat 301, clamping the PE pipe to fix it, to prevent shaking during cutting and causing cutting deviation; after the PE pipe is fixed, the hydraulic telescopic rod 502 and the servo motor are started through the external controller. 602, after the hydraulic telescopic rod 502 is started, the blade 405 is pushed to move through the connecting plate 503 and the push rod 504 to support the surface of the PE pipe, and the blade 405 is pushed downward through the hydraulic telescopic rod 502 while rotating to perform rotary cutting. After the servo motor 602 is started, the rotating sleeve 402 is driven to rotate on the surface of the connecting ring 401 through the gear 603 and the gear ring 403, and at the same time, the blade 405 is driven to rotate and cut on the surface of the PE pipe. The PE pipe is cut by rapid rotation, which can avoid deformation of the PE pipe caused by extrusion and cutting, and does not affect subsequent use.
