Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe rotary cutting equipment, and in particular to a corrugated pipe rotary cutting equipment. Background Art

[0002] A corrugated pipe, as the name implies, is a pipe with a corrugated structure on its wall. This structure enables the corrugated pipe to better adapt to deformation when subjected to pressure, tension or bending, thereby having better flexibility and durability. In the production process of corrugated pipes, since the manufactured corrugated pipes are often long, it is generally necessary to use corrugated pipe peeling equipment to cut the corrugated pipes into finished corrugated pipes of various lengths to meet the use and sales needs of the corrugated pipes.

[0003] When existing corrugated tube rotary cutting equipment cuts corrugated tubes, the cutter generally moves in a circular motion along the outer wall of the corrugated tube, thereby cutting the corrugated tube into two parts. Since part of the corrugated tube is made of elastic material, when the cutter and the tube wall of the corrugated tube contact each other, the tube wall of the corrugated tube may shrink and deform, which may cause the resistance force between the cutter and the tube wall of the corrugated tube to be too small, thereby affecting the cutting effect of the cutter on the tube wall of the corrugated tube.

[0017] 1.

[0018] 2. When the bellows is cut, the gas in the piston groove pushes the cutter, so the cutter can automatically adjust the position of the cutter according to the cutting depth of the bellows wall. The operator does not need to set an additional drive structure, which reduces the production cost of the device and the energy loss when the device is used, and reduces the maintenance cost of the equipment and the work intensity of the staff when repairing the equipment. At the same time, the position of the bellows is adjusted by the feeding mechanism, so that the cutter can directly cut bellows of different lengths when cutting the bellows, without the need for equipment adaptation and adjustment, thereby improving the efficiency of the equipment in cutting the bellows.

[0019] 3. After the above-mentioned bellows cutting is completed, the rotation speed of the support ring gradually decreases until the support ring stops rotating. At this time, the constraints and limits of the constraint plate on the left and right bellows are released in turn, and at the same time, the discharge assembly can apply a thrust to the left bellows to pull the left bellows out of the limit ring. If the bellows is not completely cut, the left bellows cannot be pulled out of the limit ring. At this time, the inability of the discharge assembly to operate causes the adjustment mechanism to stop running synchronously, and the constraint limit of the constraint plate on the bellows remains unchanged. When the subsequent feeding mechanism is running, the position of the bellows cannot be adjusted. Finally, the cutter can re-cut the bellows at that position until the cutter completes the cutting operation of the bellows at that position. There is no need to set up additional detection equipment and control equipment, which further reduces the production cost and energy loss of the device, and reduces the maintenance cost of the equipment and the work intensity of the staff when repairing the equipment.

DETAILED DESCRIPTION

[0039] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] The present invention provides a technical solution: referring to Figure 1 - Fig.17The present invention discloses a corrugated tube rotary cutting device, comprising a carrier plate 1 fixedly mounted on a base, a rotary cutting assembly 2 is provided at the left end of the top side of the carrier plate 1, and the rotary cutting assembly 2 comprises a support ring 21, and the support ring 21 is arranged at the left end above the carrier plate 1, and a plurality of storage grooves 22 are provided on the inner ring wall of the support ring 21 in a circumferential array, and a cutter 23 is slidably installed in the storage groove 22, and a piston groove 24 is provided in the ring wall of the support ring 21 at a position corresponding to the storage groove 22, and a piston rod 25 is slidably installed in the piston groove 24, and the opposite end of the piston rod 25 is fixedly connected to the corresponding cutter 23, and a plurality of air storage grooves 26 are provided in the ring wall of the support ring 21, and each air storage groove 26 is arranged on the outer peripheral side of the corresponding piston groove 24, and the interior of the air storage groove 26 is connected to the interior of the corresponding piston groove 24 through an air guide hole 27. The air storage tank 26 is connected to each other, a counterweight block 29 is slidably installed in the air storage tank 26, a sealing ring 214 is fixedly installed on the outer peripheral wall of the counterweight block 29, and the outer peripheral wall of the sealing ring 214 contacts the inner wall of the corresponding air storage tank 26, a driving mechanism 3 is provided on the outer peripheral side of the support ring 21, two limiting rings 210 are relatively arranged on the left and right sides of the support ring 21, and each limiting ring 210 is fixedly connected to the carrier plate 1 through a bracket and a bolt, the left end of the support ring 21 is inserted into the ring wall of the limiting ring 210 at the left end and is rotatably connected to the limiting ring 210 at the left end through a bearing, an annular groove 211 is opened at the middle position of the inner ring wall of the limiting ring 210, four constraint plates 212 in the shape of a quarter ring are relatively slidably installed in the annular groove 211, and an adjusting mechanism 4 is arranged in the ring wall of the limiting ring 210;

[0041] A feeding assembly 5 is provided at the right end of the top side of the carrier plate 1 , and a discharging assembly 6 is provided on the left side of the limiting ring 210 at the left end.

[0042] In this embodiment, when the improved corrugated tube rotary cutting device is used, the feeding assembly 5 pushes the corrugated tube through the two limit rings 210 and the inner hole of the support ring 21, so that the cutter 23 moves to the appropriate position on the corrugated tube, and then the driving mechanism 3 drives the support ring 21 to rotate slowly and accelerate, and drives the support ring 21 to rotate at a constant speed after the rotation speed of the support ring 21 reaches the threshold. In the process of the support ring 21 gradually increasing its rotation speed, the adjustment mechanism 4 can be driven to operate and push the constraint plate 212 in the direction of the corrugated tube until the constraint plate 212 fits with the outer wall of the corrugated tube, so that the four constraint plates 212 form a complete constraint ring, and clamp and limit the part of the corrugated tube on both sides of the cutter 23, so that the wall of the corrugated tube at the position of the cutter 23 will not produce a large degree of deformation without being subjected to a large external force, so that there is sufficient resistance between the cutter 23 and the wall of the corrugated tube, thereby enhancing the cutting effect of the cutter 23 on the wall of the corrugated tube;

[0043] During the rotation of the support ring 21, due to the mutual interference between the counterweight 29 and the inner wall of the gas storage tank 26, the rotating support ring 21 carries the counterweight 29 to make a circular motion around the bellows. At this time, due to the effect of centrifugal force, the counterweight 29 pushes part of the gas in the gas storage tank 26 into the piston groove 24 and increases the gas pressure in the piston groove 24. As the gas pressure in the gas storage tank 26 increases, a thrust can be applied to the piston rod 25 to push the cutter 23 in the direction of the bellows, so that the cutter 23 fits the outer wall of the bellows and a corresponding interference is generated between the cutter 23 and the outer wall of the bellows. At this time, due to the mutual interference between the cutter 23 and the inner wall of the storage tank 22, the rotating support ring 21 brings the cutter 23 to slide along the outer peripheral wall of the bellows, thereby cutting the bellows into two parts along the tube wall of the support ring 21, and due to the push of the piston rod 25 on the cutter 23, the cutter 23 can automatically adjust the position of the cutter 23 according to the cutting depth of the tube wall of the bellows, and no additional driving structure is required on the device, which reduces the production cost of the device and the energy loss when the device is used, and reduces the maintenance cost of the equipment and the work intensity of the staff when repairing the equipment;

[0044] After the cutting of the above-mentioned bellows is completed, the rotation speed of the support ring 21 gradually decreases until the support ring 21 stops rotating. At this time, the restraint limit of the left and right bellows by the restraining plate 212 is released in turn, and at the same time, the discharge assembly 6 can apply a thrust to the left end of the bellows, so that the left end of the bellows is pulled out from the limit ring 210. At this time, if the bellows is not completely cut off, and due to the mutual interference between the bellows and the inner wall of the limit ring 210, the discharge assembly 6 cannot pull the left end of the bellows out of the limit ring 210. The stopped discharge assembly 6 causes the adjustment mechanism 4 to stop running together, so that the restraining plate 212 continues to maintain the restraining limit state of the left and right bellows, so that the feeding assembly 5 will not continue to adjust the position of the bellows during subsequent operation, so that the cutter 23 can perform the cutting operation at this position of the bellows again until the bellows is cut. There is no need to set up additional detection equipment and control equipment, which further reduces the production cost and energy loss of the device, and reduces the maintenance cost of the equipment and the work intensity of the staff when repairing the equipment;

[0045] It should be noted that a control device for controlling the operating status of the host control device is fixedly installed at the middle position of the front side of the base.

[0046] In a further preferred embodiment of the present invention, Figure 6 , Figure 7 , Figure 8 and Fig.11As shown, a connecting hole 28 is provided on the outer peripheral wall of the support ring 21, and the interior of the connecting hole 28 is communicated with the interior of the corresponding air storage tank 26, a first spring 213 is wound around the outer peripheral side of the piston rod 25, and the two ends of the first spring 213 are respectively fixedly connected to the corresponding piston rod 25 and the inner wall of the corresponding piston groove 24, the shape of the inner ring wall of the constraint plate 212 is wavy, and the clearance of two adjacent constraint plates 212 is matched, and the shape of the inner hole of the limit ring 210 is the same as the shape of the inner hole of the support ring 21;

[0047] In this embodiment, when the counterweight 29 is located in the air storage tank 26 and slides, the outside air flows into the air storage tank 26 through the connecting hole 28, so that no negative pressure cavity is formed in the air storage tank 26 to affect the squeezing of the gas in the air storage tank 26 by the counterweight 29;

[0048] During the process of the support ring 21 stopping rotation, the centrifugal force on the counterweight 29 gradually decreases, so that the squeezing pressure of the counterweight 29 on the gas in the gas storage tank 26 is gradually reduced, and then the thrust of the gas in the piston groove 24 on the piston rod 25 is gradually reduced. At the same time, due to the push of the first spring 213 on the piston rod 25, the piston rod 25 that slides out of the piston groove 24 gradually retracts into the piston groove 24, and then the cutter 23 can be driven to retract into the storage groove 22 in time, avoiding excessive friction between the cutter 23 and the bellows and causing damage to the bellows.

[0049] In a further preferred embodiment of the present invention, Figure 4 , Figure 5 and Fig.14 As shown, the driving mechanism 3 includes a gear ring 31, which is fixedly sleeved on the outer peripheral side of the support ring 21, and the gear ring 31 is clearance-matched with the connecting hole 28, and a first motor 32 is fixedly mounted on the outer ring wall of the limiting ring 210 at the left end, and a driving gear 33 is fixedly mounted on the driving end of the first motor 32, and the driving gear 33 is meshed and connected with the gear ring 31;

[0050] In this embodiment, when the support ring 21 rotates, the first motor 32 starts to drive the driving gear 33 to rotate, thereby driving the support ring 21 to rotate through the gear ring 31, and the rotation speed of the support ring 21 slowly increases from small to large until the rotation speed of the support ring 21 reaches a threshold value, and the rotation speed of the support ring 21 remains constant. Due to the diameter ratio of the gear ring 31 and the driving gear 33, the driving force of the motor on the support ring 21 can be increased, and the friction between the cutter 23 and the bellows can be prevented from affecting the driving of the motor on the gear ring 31;

[0051] When the counterweight 29 slides in the gas storage tank 26, external gas can flow into the gas storage tank 26 through the connecting hole 28, thereby preventing the formation of a negative pressure cavity in the gas storage tank 26 during the sliding of the counterweight 29 in the gas storage tank 26, which affects the pressure of the gas in the gas storage tank 26 by the counterweight 29;

[0052] It should be noted that the diameter of the gear ring 31 is much larger than the diameter of the driving gear 33 .

[0053] In a further preferred embodiment of the present invention, Figure 1 - Figure 3 As shown, the feeding assembly 5 includes two driving rollers 51, which are arranged opposite to each other on the right side of the limiting ring 210, and the bottom end of each driving roller 51 is inserted into the carrier plate 1 and is rotatably connected to the carrier plate 1 through a bearing, and a second motor 52 is fixedly installed at the position of the bottom side of the carrier plate 1 corresponding to the driving roller 51, and the driving end of the second motor 52 is fixedly connected to the bottom end of the corresponding driving roller 51;

[0054] In this embodiment, when the bellows passes through the limit ring 210, the operator first controls the second motor 52 to start through the control host, and slowly drives the driving roller 51 to rotate slowly. Then, the operator inserts the end of the bellows between the two driving rollers 51. Due to the friction between the driving roller 51 and the bellows, the driving roller 51 clamps and pushes the bellows to move slowly to the left, so that the bellows passes through the two limit rings 210 and the inner holes of the support ring 21. The control host can control the distance the bellows moves by controlling the number of revolutions of the driving roller 51, and then controls the position of the cutter 23 on the bellows, so that the device can cut bellows of different lengths.

[0055] The above-mentioned constraint plate 212 maintains the clamping and constraint limit of the corrugated tube. At this time, when the second motor 52 drives the driving roller 51 to rotate, the corrugated tube cannot continue to move, and the driving roller 51 slides with the outer wall of the corrugated tube, so that the position of the corrugated tube remains original, and finally the cutter 23 can re-cut the corresponding position of the corrugated tube.

[0056] In a further preferred embodiment of the present invention, Figure 4 , Figure 5 and Fig.16 As shown, the discharge assembly 6 includes a plurality of bending tubes 61, which are arranged in a circular array on the left side of the limiting ring 210 located at the left end, and the bottom side of the right end of each bending tube 61 is fixedly connected to the outer ring wall of the limiting ring 210 located at the left end, and a first piston plate 62 is slidably installed in the bending tube 61, and an elastic rod 63 is fixedly installed at the center position of the left side of the first piston plate 62, and the left end of the elastic rod 63 is hemispherically arranged and extends to the outside of the corresponding bending tube 61, and the elastic rod 63 is slidably connected to the inner wall of the left end opening of the corresponding bending tube 61;

[0057] In this embodiment, after the support ring 21 stops rotating, the first piston plate 62 slides toward the elastic rod 63, thereby pushing the elastic rod 63 retracted into the bending tube 61 out of the bending tube 61 again. At this time, due to the mutual interference between the spherical end of the elastic rod 63 and the groove on the outer peripheral wall of the bending tube 61, the left bellows is pushed away from the driving roller 51, so that the two bellows are separated, and due to the clamping and limiting of the right bellows by the right constraint plate 212, the position of the end of the right bellows remains stable.

[0058] It should be noted that when the second piston plate 42 pushes the elastic rod 63 retracted into the bending tube 61 out of the bending tube 61, if the constraint limit of the left end bellows has not been released, the elastic rod 63 can continue to bend and deform, so that the second piston plate 42 can continue to push a small amount of elastic rod 63 out of the bending tube 61.

[0059] In a further preferred embodiment of the present invention, Figure 5 , Fig.14 , Fig.15 and Fig.17 As shown, a plurality of transmission gears 64 are meshed and installed on the outer circumference of the gear ring 31 in a circular array, and the driving gear 33 is located between the corresponding two transmission gears 64. A driving rod 65 is fixedly installed at the center position on the left side of the transmission gear 64. The driving rod 65 rotates through the right end tube wall of the corresponding bending tube 61 through the bearing. A sealing ring 66 is fixedly installed in the right end tube wall of the bending tube 61, and the inner ring wall of the sealing ring 66 contacts the outer circumferential wall of the corresponding driving rod 65. An impeller 67 is fixedly installed on the left end of the driving rod 65, and the impeller 67 is gap-matched with the inner wall of the corresponding bending tube 61. The bending tube 61 is filled with filling liquid.

[0060] In this embodiment, during the rotation of the gear ring 31, the rotation speed of the support ring 21 gradually increases, and the drive rod 65 can be driven by the transmission gear 64 to rotate rapidly, thereby driving the impeller 67 located in the bending tube 61 to rotate continuously and rapidly. The rotating impeller 67 pushes the filling liquid inside the bending tube 61 out, and there is no need to set up an additional driving structure, thereby reducing the production cost of the device.

[0061] In a further preferred embodiment of the present invention, Fig.17 As shown, the left end of the bending tube 61 is provided with a plurality of air inlet holes 68 in a circumferential array, and the plurality of air inlet holes 68 are arranged in a circumferential array on the outer peripheral side of the corresponding elastic rod 63;

[0062] In this embodiment, when the first piston plate 62 pulls the elastic rod 63 into the bending tube 61, external gas can flow into the bending tube 61 through the air inlet hole 68, thereby preventing the first piston plate 62 from sliding in the bending tube 61 and causing a negative pressure chamber to be generated in the bending tube 61 to affect the sliding of the first piston plate 62 in the bending tube 61;

[0063] During the sliding return of the first piston plate 62 in the bending tube 61, due to the limited amount of flowing gas at the air inlet hole 68, the filling liquid in the bending tube 61 is always subjected to a thrust during the sliding return of the first piston plate 62 in the bending tube 61, and the different thrusts of the two second springs 44 on the second piston plate 42 are combined, so that the left end constraint plate 212 is retracted into the annular groove 211 earlier than the right end constraint plate 212.

[0064] In a further preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, a support plate 69 is fixedly mounted on the left end of the top side of the carrier plate 1, and the top side of the support plate 69 is arranged in an arc shape, the outer arc edge of the top side of the support plate 69 is arranged in an arc shape, and the arc surface of the top side of the support ring 21 is coplanar with the inner ring wall of the limit ring 210;

[0065] In this embodiment, in the process of the end of the above-mentioned bellows passing through the two limit rings 210, due to the mutual interference between the bellows and the elastic rod 63, the elastic rod 63 bends and deforms in the direction away from the bellows, so that there is a sufficient distance between the elastic rods 63 for the bellows to pass through, and due to the clamping deformation of the bellows by the elastic rod 63, the end of the bellows can move directly to the top side of the support plate 69, and after the bellows moves onto the support plate 69, due to the support of the support plate 69, the limit ring 210, the support ring 21 and the drive roller 51 for the bellows, the bellows between the drive roller 51 and the support plate 69 remains in a straight state more stably.

[0066] In a further preferred embodiment of the present invention, Fig.10 - Fig.13 As shown, the adjustment mechanism 4 includes a plurality of second piston plates 42, a plurality of guide grooves 41 are provided in a circumferential array in the ring wall of the limit ring 210, the second piston plates 42 are slidably mounted in the corresponding guide grooves 41, a square rod 43 is slidably mounted in the opening of the guide groove 41, one end of the square rod 43 is fixedly connected to the center position of the corresponding second piston plate 42, the other end of the square rod 43 is fixedly connected to the middle position of the outer ring wall of the corresponding constraint plate 212, and the interior of the bending tube 61 is respectively connected to the interiors of the two corresponding guide grooves 41 through pipeline connectors;

[0067] In this embodiment, when the impeller 67 rotates, the filling liquid inside the bending tube 61 can be pushed into the guide groove 41, and the second piston plate 42 can be pushed in the direction of the bellows, and the square rod 43 of a specific length can be pushed into the annular groove 211, so that the constraint plates 212 move toward each other and fit on the outer wall of the bellows, and finally the four constraint plates 212 form a complete constraint ring, which clamps and limits part of the bellows on both sides of the support ring 21, so that this part of the bellows will not be deformed when not subjected to large external forces.

[0068] In a further preferred embodiment of the present invention, Fig.11 As shown, a second spring 44 is wound around the outer circumference of the square rod 43, and both ends of the second spring 44 are respectively fixedly connected to the corresponding second piston plate 42 and the inside of the corresponding guide groove 41, and the elastic force of the left second spring 44 is greater than the elastic force of the right second spring 44;

[0069] In this embodiment, after the gear ring 31 stops rotating, due to the push of the second spring 44 on the piston plate, the filling liquid in the guide groove 41 can automatically flow back into the bending tube 61 due to the push of the second piston plate 42. The sliding of the first piston in the bending tube 61 does not require the setting of an additional driving structure, thereby reducing the production cost of the equipment.

[0070] Working principle: When the improved corrugated tube rotary cutting device is used, the operator first starts the second motor 52 through the control host, slowly drives the driving roller 51 to rotate slowly, and then the operator inserts the end of the corrugated tube between the two driving rollers 51. Due to the friction between the driving roller 51 and the corrugated tube, the driving roller 51 clamps and pushes the corrugated tube to move slowly to the left, so that the corrugated tube passes through the inner holes of the two limit rings 210 and the support ring 21, and the control host can control the distance the corrugated tube moves by controlling the number of turns of the driving roller 51, thereby controlling the position of the cutter 23 on the corrugated tube;

[0071] It should be noted that, in the process of the bending tube 61 passing through the limit ring 210 and moving onto the support plate 69, due to the mutual interference between the bellows and the elastic rod 63, the elastic rod 63 bends and deforms in the direction away from the bellows, so that there is a sufficient distance between the elastic rods 63 for the bellows to pass through, and due to the clamping deformation of the bellows by the elastic rod 63, the end of the bellows can be directly moved to the top side of the support plate 69, and after the bellows moves onto the support plate 69, due to the support of the support plate 69, the limit ring 210, the support ring 21 and the drive roller 51 on the bellows, the bellows between the drive roller 51 and the support plate 69 is relatively stably maintained in a straight state;

[0072] After the position adjustment of the bellows is completed, the first motor 32 starts to drive the driving gear 33 to rotate, thereby driving the support ring 21 to rotate through the gear ring 31, and the rotation speed of the support ring 21 slowly increases from small to large until the rotation speed of the support ring 21 reaches a threshold value, and the rotation speed of the support ring 21 remains constant;

[0073] As the rotation speed of the support ring 21 gradually increases, the drive rod 65 can be driven to rotate rapidly through the transmission gear 64, thereby driving the impeller 67 located in the bending tube 61 to continuously rotate rapidly, and the rotating impeller 67 pushes the filling liquid inside the bending tube 61 into the guide groove 41 until the first piston plate 62 and the inner wall of the bending tube 61 contact each other, and as the first piston plate 62 slides in the bending tube 61, part of the elastic rod 63 can be pulled into the bending tube 61;

[0074] The filling liquid pushed into the guide groove 41 by the impeller 67 pushes the second piston plate 42 toward the direction of the bellows, and while compressing the second spring 44, pushes the square rod 43 of a specific length into the annular groove 211, so that the constraint plates 212 move toward each other and fit on the outer peripheral wall of the bellows, and finally the four constraint plates 212 form a complete constraint ring, clamping and limiting the part of the bellows on both sides of the support ring 21, so that the part of the bellows will not be deformed when not subjected to a large external force;

[0075] During the rotation of the support ring 21, due to the mutual interference between the counterweight 29 and the gas storage tank 26, the counterweight 29 can be driven to make a circular motion around the bellows. Due to the centrifugal force when the counterweight 29 rotates, the counterweight 29 slides in the gas storage tank 26, compresses and pushes the gas in the gas storage tank 26, and introduces part of the gas in the gas storage tank 26 into the piston groove 24 through the guide groove 41, thereby increasing the gas pressure in the piston groove 24. Due to the push of the gas in the piston groove 24 on the piston rod 25, part of the piston rod 25 is pushed into the storage tank 22, thereby pushing the cutter 23 in the direction of the bellows, so that the cutter 23 fits the outer wall of the bellows, and a corresponding interference force is generated between the cutter 23 and the outer wall of the bellows. At this time, due to the mutual interference between the cutter 23 and the inner wall of the storage tank 22, the rotating support ring 21 drives the cutter 23 to slide in contact with the outer peripheral wall of the bellows, thereby cutting the bellows into two parts along the tube wall of the support ring 21;

[0076] It should be noted that when the counterweight 29 is located in the air storage tank 26 and slides, the outside air flows into the air storage tank 26 through the connecting hole 28, so that no negative pressure cavity is formed in the air storage tank 26 to affect the squeezing of the gas in the air storage tank 26 by the counterweight 29;

[0077] After the cutting of the bellows is completed, the speed at which the first motor 32 drives the support ring 21 to rotate is gradually slowed down until the support ring 21 stops rotating. In the process of the support ring 21 gradually stopping, the centrifugal force on the counterweight 29 is gradually reduced, thereby causing the thrust of the gas in the piston groove 24 on the piston rod 25 to gradually decrease. At the same time, due to the push of the first spring 213 on the piston rod 25, the piston rod 25 that has slipped out of the piston groove 24 is gradually retracted into the piston groove 24 to reset, thereby driving the cutter 23 to be retracted into the storage groove 22 in time, thereby preventing the cutter 23 from excessively rubbing against the bellows and causing damage to the bellows.

[0078] It should be noted that, during the process of the above-mentioned cutter 23 and the wall of the corrugated pipe conflicting with each other, the corrugated pipe on both sides of the cutter 23 is constrained and limited by the constraint plate 212, so that the corrugated pipe at the position of the cutter 23 is almost not bent and deformed, and finally the wall of the corrugated pipe is prevented from shrinking and deforming, which affects the cutting of the corrugated pipe by the cutter 23;

[0079] After the support ring 21 stops rotating, the impeller 67 also stops rotating synchronously. Due to the push of the second spring 44 on the second piston plate 42, and the elastic force of the left second spring 44 is higher than the elastic force of the right second spring 44, and the limited amount of gas discharged from the air inlet 68 makes the sliding speed of the first piston plate 62 in the bending tube 61 slower. At this time, the filling liquid in the left guide groove 41 will first flow into the bending tube 61, and with the stretching of the second spring 44 in the left guide groove 41, when the elastic force of the left second spring 44 is equal to the elastic force of the right second spring 44, the remaining filling liquid in the left guide groove 41 and the filling liquid in the right guide groove 41 flow out at the same time. With the sliding of the second piston plate 42, the square rod 43 that has slipped out of the guide groove 41 can be pulled back into the guide groove 41, and finally the left constraint plate 212 is separated from the bellows first, and then the right constraint plate 212 will release the constraint limit state of the bellows.

[0080] During the process of the filling liquid flowing back into the bending tube 61, the second piston plate 42 can be pushed to slide in the direction of the elastic rod 63, and the elastic rod 63 retracted in the bending tube 61 can be pushed out of the bending tube 61 again. At this time, due to the mutual interference between the spherical end of the elastic rod 63 and the groove of the outer peripheral wall of the bending tube 61, the left bellows is pushed away from the driving roller 51, so that the two bellows are separated, and due to the clamping and limiting of the right bellows by the right constraint plate 212, the position of the end of the right bellows remains stable.

[0081] After the cutting of the above-mentioned corrugated tube is completed, the second motor 52 continues to drive the driving roller 51 to rotate, and the position of the corrugated tube is re-adjusted according to the above-mentioned method, so that the cutter 23 is aligned with the next cutting position of the corrugated tube, and according to the above-mentioned reciprocating operation, the cutting process of the corrugated tube can be continuously completed, and the corrugated tube can be cut into a corresponding number of parts, and the corrugated tube can be cut into a number of parts of different lengths at one time according to the needs;

[0082] It should be noted that, when the bellows is cut, the operator places the storage device below the left side of the carrier plate 1. After the elastic rod 63 pulls the bellows out of the stop ring 210, due to the gravity of the left end of the bellows, the bellows slides out directly from between the elastic rods 63 and falls into the storage device for storage.

[0083] During the process of the bellows being pushed by the elastic rod 63, if the tube wall of the bellows is not cut off, the elastic rod 63 cannot push the left end of the bellows out of the limit ring 210. At this time, due to the mutual interference between the elastic rod 63 and the outer groove wall of the bellows, the piston plate can hardly slide in the bending tube 61, and the filling liquid in the guide groove 41 cannot flow back into the bending tube 61. The constraint plate 212 continues to maintain the clamping and limiting state of the bellows. During the process of the bellows being pushed by the driving roller 51, since the bellows can hardly move, the driving roller 51 and the outer wall of the bellows slide against each other, thereby keeping the position of the bellows as it is. Subsequently, the support ring 21 is rotated again to complete the cutting process at this position of the bellows again until the tube wall of the bellows at this position is cut off.
