[0014] Furthermore, the method for using the mechatronic pipe cutting device is characterized in that the method for using the device is as follows:

[0015] S1: First, start the drive motor. The drive motor drives the corresponding rotating shaft to rotate. The two rotating shafts rotate synchronously under the action of two gears. Then, insert multiple pipes simultaneously into the position between the first feeding wheel and the second feeding wheel. When the pipes come into contact with the rubber air cushion, the rubber air cushion will deform after being squeezed and deform following the shape of the pipes, thereby increasing the contact area between the rubber air cushion and the pipes' surface area and increasing the friction force on the pipes. Under the action of the friction force generated between the rubber air cushion and the annular rubber pad, the pipes are pushed into the cutting box. The pipes will pass through several fixed slots and move in a limited way through the fixed slots. As the pipes continue to advance, they will contact the limit plate. Since the pipes enter the cutting box at different times, there may be a situation where the lengths of the pipes after entering the cutting box are different. The pipes that first contact the limit plate will, under the pulling force of the limit spring, offset part of the thrust generated by the friction between the annular rubber pad and the first feeding wheel, causing the pipes that first contact the limit plate to move at a slower speed. The pipes that enter the cutting box later will quickly contact the limit plate, enabling several pipes entering the cutting box to move synchronously;

[0016] S2: When the pipes push the limit plate to move, it will drive the arc plate to move to the right. When the arc plate contacts the transmission plate, it will cause the transmission plate to rotate. The transmission plate drives the transmission connecting plate to move, and the transmission connecting plate drives the L-shaped transmission plate to move to the left. The L-shaped transmission plate will contact the movable block and cause the movable block to rotate, aligning the bottom of the movable block with the cutting rectangular block. When the L-shaped transmission plate moves, it will also drive the L-shaped push rod to push the circular piston in the circular air box. The circular piston pushes the gas in the circular air box to be discharged into the hollow shaft through the air pipe. The gas will push the circular movable rod to descend. The descent of the circular movable rod will push the movable block to descend. The movable block will push the cutting rectangular block to descend. The cutting rectangular block drives the L-shaped transmission long plate to descend. The L-shaped transmission long plate drives the force-bearing plate to descend. The force-bearing plate drives several rectangular mounting plates to descend. Several rectangular mounting plates drive several C-shaped fixing blocks to descend. Several C-shaped fixing blocks drive the rubber air bag to descend and squeeze and clamp the pipes in several fixed slots. When the rubber air bag contacts the pipes, it will change the shape of the rubber air bag according to the shape of the pipes. The two sides of the C-shaped fixing block will also contact the pipes to further improve the stability of the pipes;

[0017] S3: During the downward movement of the cutting rectangular block, it will drive the cutting movable block to descend. During the downward movement of the cutting movable block, it will drive several cutting knives to descend and cut the fixed pipe. The cut pipe will instantly fall into the inclined groove and descend along the inclined groove and be discharged from the feeding port. After the pipe is cut off, the limit spring will instantly rebound under the action of the tensile force and collide with several uncut pipes, so that the lengths of the uncut pipes remain consistent. At this time, since the arc-shaped plate is separated from the transmission plate, the transmission plate will reset under the contraction action of the transmission spring. Subsequently, the movable block, the force-bearing plate, the circular movable rod, and the cutting knife will all reset under the action of the telescopic spring, the return spring, the movable spring, and the cutting spring, and continue the next cutting.

[0018] The present invention has the following beneficial effects:

[0019] (1) For a mechatronic pipe fitting cutting device of the present invention, when the pipe pushes the limit plate to move, it will drive the arc-shaped plate to move to the right. When the arc-shaped plate contacts the transmission plate, it will cause the transmission plate to rotate. The transmission plate drives the transmission connecting plate to move, and the transmission connecting plate drives the L-shaped transmission plate to move to the left. The L-shaped transmission plate will contact the movable block and cause the movable block to rotate, so that the bottom of the movable block is aligned with the cutting rectangular block. When the L-shaped transmission plate moves, it will also drive the L-shaped push rod to push the circular piston in the circular air box. The circular piston pushes the gas in the circular air box to be discharged into the hollow shaft through the air delivery pipe. The gas will push the circular movable rod to descend. The descent of the circular movable rod will push the movable block to descend. The movable block will push the cutting rectangular block to descend. The cutting rectangular block drives the L-shaped transmission long plate to descend. The L-shaped transmission long plate drives the force-bearing plate to descend. The force-bearing plate drives several rectangular mounting plates to descend. Several rectangular mounting plates drive several U-shaped fixing blocks to descend. Several U-shaped fixing blocks drive the rubber air bag to descend and squeeze and clamp the pipes in several fixing grooves. After the rubber air bag contacts the pipe, it will change the shape of the rubber air bag according to the shape of the pipe. The two sides of the U-shaped fixing block will also contact the pipe to further improve the stability of the pipe;

[0020] (2) The present invention provides a mechatronic pipe cutting device. The drive motor is started, and the drive motor drives the corresponding rotating shaft to rotate. The two rotating shafts rotate synchronously under the action of two gears, and then multiple pipes are inserted into the position between the first feeding wheel and the second feeding wheel at the same time. When the pipe contacts the rubber air cushion, the rubber air cushion will deform after being squeezed, and deform along with the shape of the pipe, thereby increasing the contact area between the rubber air cushion and the surface of the pipe, and increasing the friction force on the pipe. Under the action of the friction force generated by the rubber air cushion and the annular rubber cushion, the pipe is pushed into the cutting box. The pipe will pass through several fixed grooves and move in a limited manner through the fixed grooves. As the pipe continues to move forward, it will contact the limit plate. Due to the different times when the pipes enter the cutting box, the lengths of the pipes after entering the cutting box may be different. The pipe that first contacts the limit plate will offset a part of the thrust generated by the friction between the annular rubber pad and the feeding wheel under the pulling force of the limit spring, so that the movement speed of the pipe that first contacts the limit plate will slow down, while the pipe that enters the cutting box later will quickly contact the limit plate, so that several pipes entering the cutting box move synchronously;

[0021] (3) The present invention provides a mechatronic pipe cutting device. During the process of the rectangular cutting block descending, the movable cutting block will be driven to descend. During the process of the movable cutting block descending, the plurality of cutting knives will be driven to descend and cut the fixed pipe. The cut pipe will instantly fall into the inclined groove and be discharged from the discharge port as the inclined groove descends. After the pipe is cut, the limit spring will instantly rebound under the action of tension and collide with a plurality of uncut pipes, so that the length of the uncut pipes continues to remain consistent. At this time, since the arc plate is separated from the transmission plate, the transmission plate will reset under the contraction of the transmission spring. The successive movable blocks, force plates, circular movable rods and cutting knives will reset under the action of the telescopic spring, the return spring, the movable spring, and the cutting spring, and continue the next cutting.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1-Figure 10 As shown, the present invention is a mechatronic pipe cutting device, including a cutting box 1. An inclined groove 2 is opened in the cutting box 1.

The fixing mechanism 01 includes a fixing plate 5 fixedly installed in the cutting box 1, and further includes:

[0038] A plurality of fixing grooves 6 are opened in the fixing plate 5. A rectangular sliding groove 7 is opened in the fixing plate 5. The rectangular sliding groove 7 penetrates through a plurality of fixing grooves 6. A strip-shaped sliding rod 8 is slidably installed in the rectangular sliding groove 7. A plurality of rectangular mounting plates 9 are fixedly sleeved on the strip-shaped sliding rod 8. The plurality of rectangular mounting plates 9 are respectively distributed in a plurality of fixing grooves 6. C-shaped fixing blocks 10 are respectively fixedly installed at the bottoms of the plurality of rectangular mounting plates 9. Rubber air bags 11 are respectively fixedly installed in the plurality of C-shaped fixing blocks 10.

A plurality of return springs 13 are fixedly installed at the top of the stress plate 12. The tops of the plurality of return springs 13 are all fixedly connected to the cutting box 1.

[0039] As Figure 5 shown, a driving mechanism 02 is arranged on the front surface of the cutting box 1. The driving mechanism 02 includes two rotating shafts 14 rotatably installed in the cutting box 1. The front ends of the two rotating shafts 14 both extend outside the cutting box 1. A driving motor 15 is fixedly installed on the front surface of the cutting box 1. The driving motor 15 is fixedly connected to the corresponding rotating shaft 14. Gears 16 are respectively fixedly sleeved on the two rotating shafts 14. The two gears 16 are meshed with each other. A feeding wheel one 17 and a feeding wheel two 18 are respectively fixedly sleeved on the two rotating shafts 14.

[0040] Start the driving motor 15. The driving motor 15 drives the corresponding rotating shaft 14 to rotate. The two rotating shafts 14 rotate synchronously under the action of the two gears 16. Then, a plurality of pipes are inserted into the position between the feeding wheel one 17 and the feeding wheel two 18 at the same time, providing a power basis for advancing the pipes.

Rubber air cushions 22 are respectively fixedly sleeved on the number of U-shaped ring blocks 21.

[0042] When the pipe contacts the rubber air cushion 22, the rubber air cushion 22 will deform after being squeezed and deform following the shape of the pipe, thereby increasing the contact area between the rubber air cushion 22 and the pipe surface area, and at the same time increasing the friction force on the pipe. Under the action of the frictional force generated by the rubber air cushion 22 and the annular rubber pad 19, the pipe is pushed into the cutting box 1.

When moving, the L-shaped transmission plate 36 will also drive the L-shaped push rod 37 to push the circular piston 39 in the circular air box 38.

The two rotating shafts 14 rotate synchronously under the action of the two gears 16. Then, insert multiple pipes simultaneously into the position between the first feeding wheel 17 and the second feeding wheel 18. When the pipes come into contact with the rubber air cushion 22, the rubber air cushion 22 will deform after being squeezed and deform following the shape of the pipes, thereby increasing the contact area between the rubber air cushion 22 and the pipe surface area, and at the same time increasing the friction force on the pipes.

Since the pipes enter the cutting box 1 at different times, there may be a situation where the lengths of the pipes after entering the cutting box 1 are different. The pipes that first come into contact with the limiting plate 24 will, under the pulling force of the limiting spring 29, offset a part of the thrust generated by the friction between the annular rubber pad 19 and the first feeding wheel 17, so that the moving speed of the pipes that first come into contact with the limiting plate 24 will slow down, while the pipes that enter the cutting box 1 later will quickly come into contact with the limiting plate 24, causing several pipes entering the cutting box 1 to move synchronously;

[0053] S2: The movement of the limiting plate 24 driven by the pipes will drive the arc-shaped plate 25 to move to the right. When the arc-shaped plate 25 comes into contact with the transmission plate 32, it will cause the transmission plate 32 to rotate. The transmission plate 32 drives the transmission connecting plate 34 to move. The transmission connecting plate 34 drives the L-shaped transmission plate 36 to move to the left. The L-shaped transmission plate 36 will come into contact with the movable block 46 and cause the movable block 46 to rotate, so that the bottom of the movable block 46 is aligned with the cutting rectangular block 49. When the L-shaped transmission plate 36 moves, it will also drive the L-shaped push rod 37 to push the circular piston 39 in the circular air box 38. The circular piston 39 pushes the gas in the circular air box 38 to be discharged into the hollow shaft 42 through the air pipe 40. The gas will push the circular movable rod 43 to descend. The descent of the circular movable rod 43 will push the movable block 46 to descend. The movable block 46 will push the cutting rectangular block 49 to descend. The cutting rectangular block 49 drives the L-shaped transmission long plate 56 to descend. The L-shaped transmission long plate 56 drives the force-bearing plate 12 to descend. The force-bearing plate 12 drives several rectangular mounting plates 9 to descend. Several rectangular mounting plates 9 drive several U-shaped fixing blocks 10 to descend. Several U-shaped fixing blocks 10 drive the rubber air bags 11 to descend and squeeze and clamp the pipes in several fixing grooves 6. When the rubber air bags 11 come into contact with the pipes, they will change the shape of the rubber air bags 11 according to the shape of the pipes, and both sides of the U-shaped fixing blocks 10 will also come into contact with the pipes to further improve the stability of the pipes;

[0054] S3: During the descent of the rectangular cutting block 49, the movable cutting block 50 will be driven to descend. During the descent of the movable cutting block 50, several cutting knives 54 will be driven to descend and cut the fixed pipe. The cut pipe will instantly fall into the inclined groove 2 and be discharged from the discharge port 3 as the inclined groove 2 descends. After the pipe is cut, the limit spring 29 will instantly rebound under the action of tension and collide with several uncut pipes, so that the length of the uncut pipes continues to remain consistent. At this time, since the arc plate 25 is separated from the transmission plate 32, the transmission plate 32 will be reset under the contraction of the transmission spring 33, and the successive movable blocks 46, the force plate 12, the circular movable rod 43 and the cutting knife 54 will be reset under the action of the telescopic spring 47, the return spring 13, the movable spring 44, and the cutting spring 53, and continue to perform the next cutting.

8. A method for using a mechatronic pipe cutting device according to any one of claims 1 to 8, characterized in that: Here’s how to use it: S1: First, the driving motor (15) is started, and the driving motor (15) drives the corresponding rotating shaft (14) to rotate. The two rotating shafts (14) rotate synchronously under the action of the two gears (16), and then a plurality of pipes are simultaneously inserted into the position between the feeding wheel 1 (17) and the feeding wheel 2 (18). When the pipes contact the rubber air cushion (22), the rubber air cushion (22) will deform after being squeezed, and deform along with the shape of the pipe, thereby increasing the contact area between the rubber air cushion (22) and the surface of the pipe, and increasing the friction force on the pipe. Under the action of the friction force generated by the rubber air cushion (22) and the annular rubber cushion (19), the pipe is pushed into the cutting box (1), and the pipe passes through a plurality of fixed grooves (6) and passes through The fixed groove (6) moves in a limited position. As the pipe continues to move forward, it will contact the limit plate (24). Since the time when the pipe enters the cutting box (1) is different, the length of the pipe after entering the cutting box (1) may be different. The pipe that first contacts the limit plate (24) will offset a part of the thrust generated by the friction between the annular rubber pad (19) and the feeding wheel (17) under the pulling force of the limit spring (29), so that the movement speed of the pipe that first contacts the limit plate (24) will slow down, while the pipe that enters the cutting box (1) later will quickly contact the limit plate (24), so that the multiple pipes entering the cutting box (1) move synchronously, so that the length of the pipe is consistent during cutting, avoiding the phenomenon of unevenness. S2: The movement of the pipe pushing the limit plate (24) will drive the arc plate (25) to move to the right. When the arc plate (25) touches the transmission plate (32), it will cause the transmission plate (32) to rotate. The transmission plate (32) drives the transmission connecting plate (34) to move, and the transmission connecting plate (34) drives the L-shaped transmission plate (36) to move to the left. The L-shaped transmission plate (36) will contact the movable block (46) and cause the movable block (46) to rotate, aligning the bottom of the movable block (46) with the cutting rectangular block (49). When the L-shaped transmission plate (36) moves, it will also drive the L-shaped push rod (37) to push the circular piston (39) in the circular air box (38). The circular piston (39) pushes the gas in the circular air box (38) to be discharged into the hollow shaft (42) through the air delivery pipe (40). The gas will push the circular movable rod (43) to descend. The descent of the circular movable rod (43) will push the movable block (46) to descend. The movable block (46) will push the cutting rectangular block (49) to descend. The cutting rectangular block (49) drives the L-shaped transmission long plate (56) to descend. The L-shaped transmission long plate (56) drives the force-bearing plate (12) to descend. The force-bearing plate (12) drives a number of rectangular mounting plates (9) to descend. A number of rectangular mounting plates (9) drive a number of C-shaped fixing blocks (10) to descend. A number of C-shaped fixing blocks (10) drive the rubber airbag (11) to descend and squeeze and clamp the pipes in a number of fixing grooves (6). After the rubber airbag (11) touches the pipe, it will change the shape of the rubber airbag (11) according to the shape of the pipe. The two sides of the C-shaped fixing block (10) will also contact the pipe to further improve the stability of the pipe, preventing the pipe from shaking during cutting, resulting in a rough and uneven cross-section of the cut pipe and affecting the cutting quality. S3: During the descent of the cutting rectangular block (49), it will drive the cutting movable block (50) to descend. During the descent of the cutting movable block (50), it will drive a number of cutting knives (54) to descend and cut the fixed pipe. The cut pipe will instantly fall into the inclined groove (2) and descend along the inclined groove (2) and be discharged from the discharge port (3). After the pipe is cut off, the limit spring (29) will instantly rebound under the action of the tensile force and collide with a number of uncut pipes, keeping the lengths of the uncut pipes consistent. At this time, since the arc plate (25) has separated from the transmission plate (32), under the contraction action of the transmission spring (33), the transmission plate (32) will reset. Subsequently, the movable block (46), the force-bearing plate (12), the circular movable rod (43), and the cutting knife (54) will all reset under the action of the telescopic spring (47), the return spring (13), the movable spring (44), and the cutting spring (53) to continue the next cutting.
