[0015] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0016] like Figures 1 to 3 As shown, a stable plastic pipe cutting device of the present invention includes a base 1, four sets of positioning rollers 2, four sets of sliding blocks 3, four sets of first bolts 5, four sets of auxiliary rollers 6, four sets of arc-shaped rods 7, four sets of first springs 8, a sliding device, a cutting device, a pressing device, and a driving device. Arc-shaped grooves 4 are provided on the front and rear sides of the top of the base 1. The four sets of sliding blocks 3 slide on two sets of arc-shaped grooves 4 respectively. The four sets of positioning rollers 2 are rotatably mounted on the four sets of sliding blocks 3. Threaded holes are provided at the outer ends of the four sets of sliding blocks 3. The first bolt 5 is threadedly connected to the threaded holes of the four sets of slide blocks 3. The four sets of first bolts 5 are tightened against the base 1. The four sets of arc rods 7 are rotatably installed on the four sets of slide blocks 3 respectively. The four sets of auxiliary rollers 6 are rotatably installed on the four sets of arc rods 7. One end of the four sets of first springs 8 is connected to the four sets of arc rods 7, and the other end of the four sets of first springs 8 is connected to the four sets of slide blocks 3. The sliding device is installed on the left and right ends of the base 1. The cutting device is connected to the sliding device. The pressing device is installed on the cutting device. The driving device is installed on the pressing device.

[0017] The position of the cutting device is adjusted by the sliding device according to the diameter of the plastic pipe. After the position of the cutting device is adjusted, the four sets of sliding blocks 3 slide on the two sets of arc grooves 4. When the four sets of positioning rollers 2 slide to the designated position, the four sets of first bolts 5 are rotated. The four sets of first bolts 5 are then threadedly connected to the four sets of sliding blocks 3, and the four sets of first bolts 5 are tightened against the base 1, thereby fixing the four sets of positioning rollers 2. Then, the plastic pipe is placed between the four sets of positioning rollers 2 and the pressing device. The four sets of auxiliary rollers 6 are in contact with the plastic pipe, and the four sets of first springs 8 are deformed by elastic force. The four sets of positioning rollers 2 and the four sets of auxiliary rollers 6 cooperate to position the plastic pipe. Then, by moving the pressing device downward, the pressing device clamps and fixes the plastic pipe. At the same time, the pressing device drives the cutting device to move inward. The drive device is turned on, and the drive device drives the plastic pipe to rotate. The cutting device then cuts the rotating plastic pipe. By setting up this device, the plastic pipe can be positioned, clamped and fixed while being cut, ensuring the stability of the plastic pipe and its cutting accuracy.

[0018] The present invention provides a stable plastic pipe cutting device. The sliding device includes two sets of second bolts 9, two sets of slide rods 10, two sets of first connecting seats 11, and two sets of second springs 12. The left and right ends of the base 1 are provided with telescopic grooves, and the outer ends of the telescopic grooves of the base 1 are connected with threaded holes. The two sets of slide rods 10 slide in the two sets of telescopic grooves of the base 1. The two sets of second bolts 9 are threadedly connected to the two sets of threaded holes of the base 1, and the two sets of second bolts 9 press against the two sets of slide rods 10. The two sets of first connecting seats 11 are rotatably mounted on the two sets of slide rods 10 and are connected to the cutting device. One end of the two sets of second springs 12 is connected to the two sets of first connecting seats 11, and the other end of the two sets of second springs 12 is connected to the cutting device.

[0019] By setting the second bolt 9, slide rod 10, first connecting seat 11, and second spring 12, the position of the cutting device can be adjusted according to the diameter of the plastic pipe. By allowing the two sets of slide rods 10 to slide in the two sets of telescopic grooves of the base 1, the two sets of slide rods 10 drive the cutting device to move through the two sets of first connecting seats 11. The two sets of second springs 12 undergo elastic deformation. When the cutting device moves to the designated position, the two sets of second bolts 9 are rotated, and the two sets of second bolts 9 are threaded to the base 1. The two sets of second bolts 9 then tighten the two sets of slide rods 10, thereby fixing the cutting device. This makes it easy to adjust the position of the cutting device according to the diameter of the plastic pipe, thus enabling the cutting of plastic pipes of different sizes.

[0020] The present invention provides a stable plastic pipe cutting device, the cutting device comprising two sets of cutting blades 13, two sets of first motors 14, and two sets of moving plates 15. The two sets of cutting blades 13 are rotatably mounted on the inner ends of the two sets of moving plates 15. The two sets of first motors 14 are respectively mounted on the front ends of the two sets of moving plates 15. The output ends of the two sets of first motors 14 pass through the two sets of moving plates 15 and are connected to the front ends of the two sets of cutting blades 13. The two sets of first connecting seats 11 are rotatably connected to the bottom ends of the two sets of moving plates 15. One end of the two sets of second springs 12 is connected to the bottom ends of the two sets of moving plates 15. The pressing device is connected to the top ends of the two sets of moving plates 15.

[0021] By setting up a cutting blade 13, a first motor 14, and a moving plate 15, by turning on two sets of first motors 14, the two sets of first motors 14 drive the two sets of cutting blades 13 to rotate, and the pressing device drives the two sets of moving plates 15 to move inward, so that the two sets of rotating cutting blades 13 cut the rotating plastic pipe, thus playing the role of cutting the plastic pipe.

[0022] The present invention provides a stable plastic pipe cutting device, the pressing device comprising a pressing frame 16, two sets of connecting rods 17, two sets of coil springs 18, two sets of second connecting seats 20, two sets of third springs 21, a handle 22, four sets of fourth springs 24, and four sets of wheel frames 29. The two sets of connecting rods 17 are rotatably connected to the left and right sides of the bottom end of the pressing frame 16 respectively through the two sets of coil springs 18. The bottom ends of the two sets of connecting rods 17 are rotatably connected to the two sets of second connecting seats 20. The two sets of second connecting seats 20 are rotatably mounted on the top ends of two sets of movable plates 15. One end of each of the two sets of third springs 21 is connected to one of the two sets of second connecting seats 20, and the other end of each of the two sets of third springs 21 is connected to the top of each of the two sets of moving plates 15. Four sets of telescopic grooves are provided in the middle of the bottom end of the pressure frame 16. Four sets of wheel frames 29 slide in the four sets of telescopic grooves of the pressure frame 16 respectively. Four sets of fourth springs 24 are respectively sleeved on the four sets of wheel frames 29. The top of each of the four sets of fourth springs 24 is connected to the bottom end of the pressure frame 16. The bottom of each of the four sets of fourth springs 24 is connected to the four sets of wheel frames 29. The handle 22 is installed on the top of the pressure frame 16.

[0023] By setting up a pressure frame 16, connecting rod 17, coil spring 18, second connecting seat 20, third spring 21, fourth spring 24, and wheel frame 29, the pressure frame 16 is pressed down by the handle 22. The four sets of wheel frames 29, in cooperation with the four sets of fourth springs 24, clamp and fix the plastic pipe. The downward movement of the pressure frame 16 causes the two sets of connecting rods 17 to deform, and the two sets of coil springs 18 to deform with elastic force. The two sets of pulleys 27 drive the two sets of moving plates 15 to move inward through the two sets of second connecting seats 20, thereby enabling the two sets of cutting blades 13 to cut the plastic pipe. This not only serves to clamp and fix the plastic pipe, but also to drive the two sets of cutting blades 13 to move inward to cut the plastic pipe.

[0024] The present invention provides a stable plastic pipe cutting device, the driving device including a second motor 23, a drive wheel 25, a belt 26 and a power wheel 28. The second motor 23 is installed at the front end of the pressure frame 16, the drive wheel 25 is installed at the output end of the second motor 23, the power wheel 28 is rotatably installed at the middle of the bottom end of the pressure frame 16, and a pulley 27 is provided at the front end of the power wheel 28. The drive wheel 25 and the pulley 27 rotate synchronously through the belt 26.

[0025] By setting up a second motor 23, a drive wheel 25, a belt 26, a pulley 27, and a power wheel 28, when the second motor 23 is turned on, the drive wheel 25 drives the pulley 27 to rotate via the belt 26, the pulley 27 drives the power wheel 28 to rotate, and the power wheel 28 drives the plastic pipe to rotate, thereby enabling the two sets of cutting blades 13 to cut the plastic pipe in all directions and drive the plastic pipe to rotate.

[0026] This invention discloses a stable plastic pipe cutting device. During operation, the positions of two sets of cutting blades 13 are first adjusted according to the diameter of the plastic pipe. Two sets of sliding rods 10 slide within two sets of telescopic grooves on the base 1. These sliding rods 10, via two sets of first connecting seats 11, drive two sets of moving plates 15. Two sets of second springs 12 deform due to elasticity. When the two sets of cutting blades 13 reach their designated positions, two sets of second bolts 9 are rotated, threaded onto the base 1, and press against the sliding rods 10, thus fixing the moving plates 15. Then, four sets of sliding blocks 3 slide on two sets of arc-shaped grooves 4. When the four sets of positioning rollers 2 slide to their designated positions, four sets of first bolts 5 are rotated, threaded onto the four sets of sliding blocks 3, and press against the base 1, thus fixing the positioning rollers 2. Finally, the plastic pipe is placed between the four sets of positioning rollers 2 and the pressing device. Four sets of auxiliary rollers 6 contact the plastic pipe, and four sets of first springs 8 deform with elastic force. The four sets of positioning rollers 2 and four sets of auxiliary rollers 6 work together to position the plastic pipe. Then, two sets of first motors 14 are turned on, which drive two sets of cutting blades 13 to rotate. Then, the handle 22 presses down on the pressure frame 16. The four sets of wheel frames 29 clamp and fix the plastic pipe with the cooperation of four sets of fourth springs 24. The power wheel 28 contacts the plastic pipe. The second motor 23 is turned on, and the drive wheel 25 drives the pulley 27 to rotate through the belt 26. The pulley 27 drives the power wheel 28 to rotate, and the power wheel 28 drives the plastic pipe to rotate. The downward movement of the pressure frame 16 causes the two sets of connecting rods 17 to deform, and the two sets of coil springs 18 deform with elastic force. The two sets of pulleys 27 drive the two sets of moving plates 15 to move inward through the two sets of second connecting seats 20, so that the two sets of rotating cutting blades 13 can cut the rotating plastic pipe.

[0027] The present invention provides a stable plastic pipe cutting device.
