Description

Technical Field

[0001] This invention relates to the field of corrugated pipe processing technology, and specifically to a circumferential cutting device for corrugated pipe processing. Background Technology

[0002] A bellows is a tubular elastic element with transverse corrugations that can generate displacement under pressure, axial force, or bending moment. It is primarily used as a sensitive element in pressure measuring instruments, or to convert pressure into displacement and force, and also as a sealing, isolation, and compensation element. It is widely used in instruments (pressure sensors), industrial pipelines (compensation for thermal deformation, vibration damping), automotive manufacturing (wiring harness protection, exhaust systems), building drainage, aerospace, and other applications. During the production and processing of bellows, because they need to be cut to precise lengths, ordinary shearing or sawing can easily apply excessive pressure locally, causing problems such as flattening, cracking, or waveform collapse. Circumferential cutting, using a rolling blade to gradually cut in, distributes the cutting force evenly, effectively preventing stress concentration and maintaining the original structural integrity of the pipe. Furthermore, circumferential cutting ensures accurate dimensions and high end face perpendicularity after cutting, facilitating subsequent connection and assembly with other components.

[0003] Currently, most rotary circumferential cutting devices for corrugated pipe processing on the market are based on vision positioning, servo feeding, and rotary infeed as their core structures. While they can achieve automated fixed-length cutting of corrugated pipes, they generally suffer from a lack of surface pretreatment in actual production. Existing circumferential cutting equipment typically lacks a dedicated external wall cleaning structure. During extrusion, transfer, and storage, dust, plastic debris, and other impurities easily adhere to the outer wall of the corrugated pipe. These impurities, adhering to the corrugated grooves and outer wall, interfere with the recognition accuracy of the vision positioning system after entering the device, causing image deviation and inaccurate positioning. This leads to inconsistent cutting lengths, skewed cuts, and non-perpendicular end faces. Simultaneously, impurities accelerate blade wear during cutting, causing burrs and rough edges on the cut, compromising the smoothness and sealing of the corrugated pipe cut. Therefore, the lack of an external wall cleaning structure has become a prominent problem affecting cutting quality and reducing equipment reliability in the practical application of existing corrugated pipe circumferential cutting devices. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a circumferential cutting device for bellows processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A corrugated pipe circumferential cutting device includes a device body with an inlet and an outlet at both ends. A fixing plate is installed on the outer wall of the device body near the inlet, and a cleaning mechanism for automatically cleaning the surface of the corrugated pipe to be circumferentially cut is provided at the bottom of the fixing plate. Two rotating frames are provided on the outer wall of the device body near the outlet, and each of the two rotating frames has a placement groove for temporarily storing the circumferentially cut corrugated pipe. A detection mechanism for detecting and processing the cut part of the circumferentially cut corrugated pipe is provided on one of the rotating frames away from the device body. A traction mechanism for guiding the circumferentially cut corrugated pipe into the two placement grooves is also provided at the end of the device body near the outlet.

[0006] Optionally, a control terminal is installed on the top of the fixed plate, and a first motor is installed on the outer wall of the device body near the two rotating frames. The output end of the first motor is connected to the adjacent rotating frame, and the two rotating frames are connected by a first electric telescopic rod.

[0007] Optionally, the cleaning mechanism includes a horizontal groove opened at the bottom of the fixed plate, a first slider installed inside the horizontal groove, an installation block installed at the bottom end of the first slider, a circular shell provided at the bottom end of the installation block, two circular connecting brackets installed on the outer wall of the circular shell, and multiple arc-shaped grooves opened at the bottom end of the installation block, with the two connecting brackets rotatably connected to two of the arc-shaped grooves.

[0008] Optionally, a second motor is installed inside the mounting block, a gear is installed at the output end of the second motor, and a gear ring is installed at the center of the outer wall of the circular housing, with the gear ring meshing with the gear.

[0009] Optionally, multiple sets of second electric telescopic rods are installed inside the circular housing. Each set of second electric telescopic rods has a mounting plate installed at its telescopic end, and a cleaning brush is installed on the side of each mounting plate away from the inner wall of the circular housing.

[0010] Optionally, the outer walls of both rotating frames are rotatably equipped with multiple rotating plates, the same number as the placement slots, which can block multiple placement slots.

[0011] Optionally, the detection mechanism includes an installation slot inside one of the rotating frames, a third motor is installed inside the installation slot, a third electric telescopic rod is installed at the output end of the third motor, a rectangular block is installed at the telescopic end of the third electric telescopic rod, and a rotating block is rotatably installed at the top of the rectangular block.

[0012] Optionally, an industrial camera is mounted on one side of the outer wall of the rotating block, a first circular block is mounted on the other side of the outer wall of the rotating block, a first airbag is mounted on the outer wall of the first circular block, a fourth electric telescopic rod is mounted on the outer wall of the device body near the discharge port, a hollow plate is mounted on the telescopic end of the fourth electric telescopic rod, a connector for connecting to an externally preset inflation device is provided on the outer wall of the hollow plate, a second circular block is mounted on the outer wall of the hollow plate away from the fourth electric telescopic rod, and a second airbag is mounted on the outer wall of the second circular block.

[0013] Optionally, an electric push rod is installed inside the rotating block, and a rubber block is installed at the telescopic end of the electric push rod.

[0014] Optionally, the traction mechanism includes a vertical groove opened on the outer wall of the device body near the discharge port. A second slider is installed inside the vertical groove. A telescopic cylinder is installed at the end of the second slider away from the vertical groove. A mounting seat is installed at the telescopic end of the telescopic cylinder. A double-ended screw is rotatably installed inside the mounting seat. Two vertical plates are threaded on the outer wall of the double-ended screw. Clamping plates are installed on the outer wall of the two vertical plates on the side where their bottom ends are close to each other.

[0015] The beneficial effects of this invention are: 1. In this invention, before the corrugated pipe enters the device body for circumferential cutting, a cleaning mechanism can automatically clean the impurities attached to the outer wall of the corrugated pipe. This prevents the impurities on the outer wall of the corrugated pipe from affecting the recognition accuracy of the visual positioning system, thus avoiding problems such as inconsistent cutting lengths, skewed cuts, and non-perpendicular end faces. This improves the cutting quality and accuracy of the corrugated pipe by the device body, thereby simultaneously improving the reliability of the device body in actual use.

[0016] 2. In this invention, if the tracked feeding mechanism inside the device body malfunctions or is worn excessively, making it impossible to feed subsequent corrugated pipes into the rotating cutter head for circumferential cutting, multiple cleaning brushes can be used to clean the surface of the corrugated pipe. Then, the extension ends of multiple sets of second electric telescopic rods can be controlled to continue to extend, ensuring that the multiple cleaning brushes have a clamping effect on the outer wall of the corrugated pipe. The first slider can be controlled to move towards the device body inside the transverse groove, thereby driving subsequent corrugated pipes into the device body for further circumferential cutting. This improves the applicability of the cleaning mechanism during use and ensures that the device body can complete the circumferential cutting of the corrugated pipes on time.

[0017] 3. In this invention, after the corrugated pipe is circumcised, it is discharged outward through the outlet. At this time, the corrugated pipe discharged outward is placed in a horizontal straight position in the corresponding placement slots inside the two rotating frames through the cooperation between the two rotating frames and other components. Subsequently, the second corrugated pipe discharged outward from the outlet can be rotated by controlling the first motor to rotate the two rotating frames 60 degrees, so that the second placement slot on the two rotating frames rotates to the same axis as the outlet, so that the second corrugated pipe can be placed inside the two second placement slots. After the two rotating frames are adjusted by 60 degrees two or three times, the first placement slot on the two rotating frames rotates to the bottom. The corresponding rotating plates on the outside of the two rotating frames can be controlled to rotate outward and open, so that the corrugated pipe inside the first placement slot can automatically fall downward into the preset collection container or the top of the conveyor belt. This achieves the effect of flexible feeding and accurate collection of the corrugated pipe after cutting. There is no need for workers to sort and collect the corrugated pipe after cutting, thus improving the processing efficiency of corrugated pipe.

[0018] 4. In this invention, since the two rotating frames are connected and fixed by the first electric telescopic rod, the two rotating frames can be extended and adjusted within a specified length range, so that corrugated pipes of different lengths that are cut and processed by the device body can be temporarily placed and transferred for unloading, thereby improving the applicability of the two rotating frames in actual use.

Detailed Implementation

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1-11 A corrugated pipe circumferential cutting device includes a device body 1. The device body 1 has an inlet 2 and an outlet 3 at its two ends. A fixing plate 4 is installed on the outer wall of the device body 1 near the inlet 2. A cleaning mechanism for automatically cleaning the surface of the corrugated pipe to be circumferentially cut is provided at the bottom of the fixing plate 4. Two rotating frames 11 are provided on the outer wall of the device body 1 near the outlet 3. Each rotating frame 11 has a placement groove 23 for temporarily storing the circumferentially cut corrugated pipe. One of the rotating frames 11, away from the device body 1, is equipped with a detection mechanism for detecting and processing the cut portion of the circumferentially cut corrugated pipe. A traction mechanism is also provided at the end of the device body 1 near the outlet 3 to guide the circumferentially cut corrugated pipe into the two placement grooves 23 for placement. The corrugated pipe enters the device body 1 through the inlet 2 for circumferential cutting and is then discharged through the outlet 3, completing the circumferential cutting process for long corrugated pipes.

[0024] As a technical optimization of the present invention, a control terminal 5 is installed on the top of the fixing plate 4, and a first motor 10 is installed on the outer wall of the device body 1 near the two rotating frames 11. The output end of the first motor 10 is connected to the adjacent rotating frame 11, and the two rotating frames 11 are connected by a first electric telescopic rod 12. After the first motor 10 is started, it can drive the two connected rotating frames 11 to rotate together. Since the two rotating frames 11 are connected and fixed by the first electric telescopic rod 12, the telescopic end of the first electric telescopic rod 12 can drive one of the rotating frames 11 to move and adjust synchronously during the telescopic adjustment process.

[0025] As an optimized technical solution of the present invention, the cleaning mechanism includes a horizontal groove 13 opened at the bottom of the fixed plate 4. A first slider 14 is installed inside the horizontal groove 13. An mounting block 6 is installed at the bottom end of the first slider 14. A circular shell 7 is provided at the bottom end of the mounting block 6. Two circular connecting brackets 15 are installed on the outer wall of the circular shell 7. Multiple arc-shaped grooves 20 are opened at the bottom end of the mounting block 6. The two connecting brackets 15 are rotatably connected to two of the arc-shaped grooves 20. A first linear motor is preset inside the horizontal groove 13. The first linear motor can drive the first slider 14 to move back and forth inside the horizontal groove 13, thereby driving the mounting block 6 and the circular shell 7 to move and adjust together at the bottom of the fixed plate 4. The circular shell 7 is rotatably connected to the mounting block 6 by means of the two connecting brackets 15 provided on its outer wall.

[0026] As a technical optimization of the present invention, a second motor 21 is installed inside the mounting block 6, and a gear 22 is installed at the output end of the second motor 21. A gear ring 16 is installed at the center of the outer wall of the circular housing 7, and the gear ring 16 meshes with the gear 22. After the second motor 21 is started, it can drive the gear 22 to rotate, which in turn drives the meshing gear ring 16 and the circular housing 7 to rotate and adjust together at the bottom end of the mounting block 6.

[0027] As a technical optimization of the present invention, multiple sets of second electric telescopic rods 17 are installed inside the circular housing 7. Each telescopic end of the multiple sets of second electric telescopic rods 17 is equipped with a mounting plate 18. Cleaning brushes 19 are installed on the side of each mounting plate 18 away from the inner wall of the circular housing 7. During the telescopic process, the telescopic ends of the multiple sets of second electric telescopic rods 17 can drive the mounting plates 18 and cleaning brushes 19 to move and adjust together inside the circular housing 7. This ensures that after the cleaning brushes 19 abut against the outer wall of the corrugated pipe to be circumcised, as the circular housing 7 rotates, the cleaning brushes 19 clean dust and other impurities from the outer wall of the corrugated pipe. Combined with a pre-installed vacuum head inside the circular housing 7, a pre-installed vacuum cleaner is activated, allowing the vacuum head to automatically remove the impurities cleaned by the cleaning brushes 19, thus improving the cleaning effect.

[0028] As a technical optimization of the present invention, multiple rotating plates 24, the same number as the placement slots 23, are rotatably mounted on the outer walls of both rotating frames 11. The multiple rotating plates 24 can block the multiple placement slots 23. Multiple servo motors are pre-installed inside both rotating frames 11, and the output ends of the multiple servo motors are respectively connected to the rotating part of one end of the corresponding rotating plate 24, thereby driving the multiple rotating plates 24 to rotate and adjust.

[0029] As an optimized technical solution of the present invention, the detection mechanism includes an installation slot 27 inside one of the rotating frames 11. A third motor 29 is installed inside the installation slot 27. A third electric telescopic rod 28 is installed at the output end of the third motor 29. A rectangular block 25 is installed at the telescopic end of the third electric telescopic rod 28. A rotating block 26 is rotatably installed at the top of the rectangular block 25. After the third motor 29 is started, it can drive the third electric telescopic rod 28, the rectangular block 25, and the rotating block 26 to rotate and adjust together. During the telescopic process of the third electric telescopic rod 28, it can drive the rectangular block 25 and the rotating block 26 to move and adjust at one end of one of the rotating frames 11. A fifth motor is preset inside the rotating block 26. The output end of the fifth motor is connected to the rotating part of the rotating block 26, thereby driving the rotating block 26 to rotate and adjust at the top of the rectangular block 25.

[0030] As a technical optimization of the present invention, an industrial camera 30 is installed on one side of the outer wall of the rotating block 26, a first circular block 34 is installed on the other side of the outer wall of the rotating block 26, a first airbag 33 is installed on the outer wall of the first circular block 34, a fourth electric telescopic rod 31 is installed on the outer wall of the device body 1 near the discharge port 3, a hollow plate 40 is installed at the telescopic end of the fourth electric telescopic rod 31, a connector 41 for connecting to an externally preset inflation device is provided on the outer wall of the hollow plate 40, a second circular block 42 is installed on the outer wall of the hollow plate 40 away from the fourth electric telescopic rod 31, and a second airbag 43 is installed on the outer wall of the second circular block 42. The industrial camera 30 is a high-precision camera from the Allied Vision Alvium G1 series, specifically the Alvium G1-1240, G1-2230, or G1-5010 models, facilitating automatic detection of the corrugated pipe's cuts. The first airbag 33 can be connected to an externally pre-set inflation device and hose to ensure it is inflated during use. During the extension and retraction of the fourth electric telescopic rod 31, the hollow plate 40, the second circular block 42, and the second airbag 43 can be moved and adjusted. The end of the second airbag 43 furthest from the hollow plate 40 is equipped with a one-way valve. After sufficient gas is injected to inflate the second airbag 43, any subsequent gas can be discharged through the one-way valve. This allows the second airbag 43 and other components to work in conjunction with the first airbag 33 and other components during use to inflate and restore small and easily treated depressions on the corrugated pipe's surface, facilitating subsequent processing of the corrugated pipe.

[0031] As a technical optimization of the present invention, an electric push rod 44 is installed inside the rotating block 26, and a rubber block 32 is installed at the telescopic end of the electric push rod 44. During the extension and retraction process, the telescopic end of the electric push rod 44 can drive the rubber block 32 to move and adjust.

[0032] As a technical optimization of the present invention, the traction mechanism includes a vertical groove 8 opened on the outer wall of the device body 1 near the discharge port 3. A second slider 35 is installed inside the vertical groove 8. A telescopic cylinder 9 is installed at the end of the second slider 35 away from the vertical groove 8. A mounting seat 36 is installed at the telescopic end of the telescopic cylinder 9. A double-ended screw 37 is rotatably installed inside the mounting seat 36. Two vertical plates 38 are threadedly installed on the outer wall of the double-ended screw 37. Clamping plates 39 are installed on the outer wall of the two vertical plates 38 on the side where their bottom ends are close together. A second linear motor is preset inside the vertical groove 8. The second linear motor can drive the second slider 35 to move up and down inside the vertical groove 8, thereby driving the telescopic cylinder 9, the mounting seat 36, and the clamping plates 39 to move up and down together for adjustment. A fourth motor is preset on one side of the outer wall of the mounting seat 36. The output end of the fourth motor is connected to one end of the double-ended screw 37, thereby driving the double-ended screw 37 to rotate inside the mounting seat 36, so as to drive the two vertical plates 38 and the clamping plates 39 to move and adjust in the direction of approaching and moving away.

[0033] In this invention, when the user uses the device, the pre-shaped corrugated pipe is inserted into the device body 1 through the feed port 2. After the corrugated pipe enters the tracked feeding mechanism inside the device body 1, the feeding servo motor starts and drives the track to convey the corrugated pipe forward at a constant speed until it reaches the camera's field of view. The high-speed camera, preset inside the device body 1, automatically takes pictures of the surface of the corrugated pipe. The background control system identifies the peaks, troughs, joints, or markers, calculates the precise cutting position of the corrugated pipe, and displays the relevant cutting information on the screen of the control terminal 5. Subsequently, the motor-driven pressing mechanism inside the device body 1 presses the corrugated pipe... The corrugated tube is centered and pressed tightly. Then, the rotating cutter head inside the device body 1, which is driven by a 1.5KW servo motor, is responsible for cutting the corrugated tube. After reaching the set speed, the rotating cutter head is controlled to rotate at high speed around the corrugated tube. The motor drives the rotating cutter head to make a micro-feeding cut, gradually cutting into the wall of the corrugated tube. Then, the rotating cutter head is controlled to make a uniform cut around the circumference of the corrugated tube, completely cutting the corrugated tube. After the corrugated tube is cut, the rotating cutter head is controlled to quickly return to the origin and stop rotating. The tube pressing mechanism is released, releasing the clamp on the cut corrugated tube. Finally, the cut tube is sent out by the conveyor belt. Then, the system automatically enters the cutting cycle for the next corrugated tube, realizing the continuous automatic circumferential cutting of the corrugated tube by the device body 1.

[0034] When the corrugated pipe is transported to the inside of the device body 1 for circumferential cutting, the corrugated pipe can be passed through the inside of the circular housing 7. Then, the telescopic ends of multiple sets of second electric telescopic rods 17 are extended together, causing multiple cleaning brushes 19 to abut against the outer wall of the corrugated pipe. During the process of controlling the second motor 21 to drive the gear 22 to rotate, the circular housing 7 can be driven to rotate synchronously at the bottom of the mounting block 6, so that the multiple cleaning brushes 19 can rotate to clean the impurities attached to the outer wall of the corrugated pipe. With the help of the preset dust collection equipment, the impurities cleaned by the multiple cleaning brushes 19 can be automatically removed, so as to achieve the effect of automatic cleaning of the surface of the corrugated pipe to be cut, and avoid the surface of the corrugated pipe being attached with impurities, which would affect the quality of its circumferential cutting.

[0035] Since the cleaning mechanism can be synchronously adjusted by the back-and-forth movement of the first slider 14 inside the transverse groove 13, if the tracked feeding mechanism inside the device body 1 malfunctions or is worn excessively and can no longer transport subsequent corrugated pipes to the rotating cutter head for circumferential cutting, after multiple cleaning brushes 19 clean the surface of the corrugated pipe, the telescopic ends of multiple sets of second electric telescopic rods 17 can be controlled to continue to extend. After ensuring that the multiple cleaning brushes 19 can clamp the outer wall of the corrugated pipe, the first slider 14 can be controlled to move inside the transverse groove 13 towards the device body 1, thereby driving the subsequent corrugated pipes into the device body 1 for further circumferential cutting. This improves the applicability of the cleaning mechanism during use and ensures that the device body 1 can complete the circumferential cutting of the corrugated pipes on time.

[0036] After the corrugated pipe is circumcised, it is discharged outward through the discharge port 3. At this time, one end of the corrugated pipe can just pass through the placement slot 23 on one of the rotating frames 11. Then, the second slider 35 is controlled to move downward inside the vertical slot 8, driving the mounting base 36 and the two clamping plates 39 to move downward together until the two clamping plates 39 move to both sides of the corrugated pipe passing through the placement slot 23. Then, the double-headed screw 37 is controlled to drive the two vertical plates 38 and the clamping plates 39 to move in a closer direction, clamping and fixing one end of the corrugated pipe. As the corrugated pipe is slowly discharged outward from the discharge port 3, the telescopic cylinder 9 can be controlled to slowly extend until one end of the corrugated pipe is guided into the corresponding placement slot 23 outside the other rotating frame 11. This allows the cut corrugated pipe to be placed in a horizontal straight state in the corresponding placement slot 23 inside the two rotating frames 11. Two corrugated pipes discharged from the outlet 3 can be rotated 60 degrees by controlling the first motor 10 to drive the two rotating frames 11 to rotate. This causes the second placement slot 23 on the two rotating frames 11 to rotate to the same axis as the outlet 3, so that the traction mechanism can guide the second corrugated pipe and place it inside the two second placement slots 23. After the two rotating frames 11 have been rotated 60 degrees two or three times, the first placement slot 23 on the two rotating frames 11 will rotate downwards. The corresponding rotating plates 24 on the outside of the two rotating frames 11 can be controlled to rotate outwards and open, so that the corrugated pipe inside the first placement slot 23 can automatically fall downwards into the preset collection container or the top of the conveyor belt. This achieves the effect of flexible unloading and accurate collection of the corrugated pipes after cutting and processing. Afterwards, no workers are required to sort and collect the corrugated pipes after cutting and processing, thus improving the processing efficiency of the corrugated pipes.

[0037] Since the two rotating frames 11 are connected and fixed by the first electric telescopic rod 12, the two rotating frames 11 can be extended and adjusted within a specified length range, so that corrugated pipes of different lengths cut and processed by the device body 1 can be temporarily placed and transferred for unloading, thereby improving the applicability of the two rotating frames 11 in actual use.

[0038] To ensure that the cut of the corrugated pipe is flat, burr-free, and without collapsed edges after cutting, the corrugated pipe can be guided into the placement slots 23 on the two rotating frames 11 by the traction mechanism. Then, the industrial camera 30 on the side of the rotating frame 11 away from the device body 1 can be controlled to automatically identify and detect the cut of the corrugated pipe. After the first motor 10 drives the two rotating frames 11 to rotate and adjust, the third motor 29 drives the third electric telescopic rod 28 and other components to adaptively reverse, thereby rotating and adjusting the position of the industrial camera 30. This ensures that the industrial camera 30 can also automatically identify and process the cut of the next corrugated pipe, avoiding the problem that the industrial camera 30 rotates synchronously with the rotating frame 11 and cannot identify and detect the cut of subsequent corrugated pipes.

[0039] If the corrugated pipe has defects in its cut after inspection, the two rotating frames 11 can be used to rotate it downwards, while the two corresponding rotating plates 24 keep the placement slots 23 blocked, preventing the corrugated pipe from falling downwards from the inside of the two placement slots 23. This continues until the two rotating frames 11 continue to rotate the corrugated pipe to a position close to the back of the device body 1. Then, the two rotating plates 24 are controlled to release the blockage of the placement slots 23, causing it to be discharged downwards to a position close to the back of the device body 1. This achieves the effect of classifying and discharging qualified and unqualified corrugated pipes, avoiding the problem of them being collected in the same position or in the same container, requiring further screening later.

[0040] If the surface of the corrugated pipe after cutting by the device body 1 has a small and easily repairable dent, in order to avoid subsequent manual or related quality inspection equipment judging it as unqualified pipe, after the corrugated pipe cut is inspected and approved, the rotating block 26 can be controlled to rotate and adjust, so that the rubber block 32 rotates to a position close to the corrugated pipe. After ensuring that the rubber block 32 and the corrugated pipe are on the same axis, since the outer diameter of the rubber block 32 matches the inner diameter of the corrugated pipe, the two clamping plates 39 of the traction mechanism can be used to clamp and fix the corrugated pipe. Then, the telescopic end of the telescopic cylinder 9 can be controlled to continue to extend, pushing the corrugated pipe towards the distance. The device continues to move away from the main body 1, causing the end of the corrugated pipe away from the main body 1 to extend outward from the inside of the placement groove 23. Then, the extension end of the third electric telescopic rod 28 is controlled to drive the rotating block 26 and other components to move adaptively away from the rotating frame 11. Next, the two clamps 39 of the traction mechanism are controlled to move to the sides near the end of the corrugated pipe that extends out of the placement groove 23 and clamp and stabilize its end. Then, the extension end of the fourth electric telescopic rod 31 is controlled to extend, driving the rubber block 32 to be inserted into the inside of one end of the corrugated pipe, and automatically cleaning the inside of one end of the corrugated pipe.

[0041] Next, the telescopic end of the fourth electric telescopic rod 31 is controlled to retract the rubber block 32 back to its original position, and the rotating block 26 is controlled to rotate and adjust again, causing the first circular block 34 to rotate to a position close to the bellows. Then, the rotating frame 11 is controlled to rotate and adjust, so that the bellows rotates to a position coaxial with the electric push rod 44. At this time, the rotating block 26 and other components rotate synchronously with the rotation of the rotating frame 11 to a position coaxial with the electric push rod 44. Then, the telescopic end of the third electric telescopic rod 28 is controlled to retract, causing the first circular block 34 and the first airbag 33, whose diameter is much smaller than the inner diameter of the bellows, to extend into the cleaned end of the bellows. The externally preset inflation device is controlled to inflate the first airbag 33, so that the inflated first airbag 33 can be aligned with the end of the bellows. The inner wall fits tightly, effectively sealing one end of the corrugated pipe. Then, the extension end of the electric push rod 44 is controlled to extend, causing the second circular block 42 and the second airbag 43, whose diameter is much smaller than the inner diameter of the corrugated pipe, to extend into the other end of the corrugated pipe. After the second airbag 43 is inflated and fits against the inner wall of the other end of the corrugated pipe, the inflation device continuously delivers air into the interior of the second airbag 43, causing the second airbag 43 to discharge excess air outward through the one-way valve into the interior of the corrugated pipe. This inflates the interior of the corrugated pipe, promoting the restoration of dents on the surface of the corrugated pipe. This achieves the effect of automatically repairing dents with small surface areas that are relatively easy to handle, which is beneficial for subsequent processing of the corrugated pipe and reduces the problem of misjudging such corrugated pipes as unqualified pipes.
