Description

[Technical Field]

[0001] This invention relates to the field of pipe processing equipment, and more particularly to a multi-station winding device. [Background Technology]

[0002] After rolling, the tubing needs to be stored. The tubing can be stored as straight tubes or wound into coils. To wind the tubing into coils, a winding device is required. A typical winding device includes a frame and multiple winding racks arranged around the center of the frame. During winding, the frame rotates to allow the tubing to wrap around the winding racks, forming a coil. After winding, the coil needs to be removed from the winding device, but this results in a long interval between the second winding and a low winding efficiency. To address this, an existing winding device includes a frame and two winding mechanisms mounted on the frame, arranged axially along the tubing. When one winding mechanism finishes winding, the other can begin winding. While this improves winding efficiency, the two winding mechanisms still significantly hinder the winding and unwinding process, preventing a substantial increase in overall efficiency. [Summary of the Invention]

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art by proposing a multi-station winding device, which improves the winding efficiency of pipe materials.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A multi-station winding device includes a support frame and a winding mechanism mounted on the support frame for winding tube material. The upper end of the support frame has multiple processing stations along the circumferential direction, including a loading station, an intermediate processing station, a unloading station, and a preparatory station. Each processing station is equipped with a winding mechanism, which can slide relative to the support frame in the circumferential direction to switch between processing stations. The winding mechanism includes a winding frame and a rotating roller rotatably mounted on the winding frame for winding tube material. The winding frame includes a crossbeam, a first frame at one end of the crossbeam, and a second frame at the other end of the crossbeam. The first frame has a bending guide mechanism for bending and guiding the tube material around the rotating roller, and the second frame has a rotating component for driving the rotating roller to rotate.

[0006] Based on the above scheme, the upper end of the support frame is provided with a main shaft, the winding mechanism includes a winding frame, a support arm rotatably mounted on the main shaft and fixedly connected to the winding frame, the support arms of multiple winding frames are coaxially arranged and independent of each other, a first chain is embedded on the support frame, and a first sprocket meshing with the first chain and a first motor driving the first sprocket to rotate are provided on the support arm.

[0007] Based on the above solution, the winding device further includes a distance retaining member for maintaining the distance between two connected winding mechanisms. The distance retaining member is a top rod disposed on the support arm, and the top rods on two adjacent support arms can abut against each other when the winding mechanism slides relative to the support frame.

[0008] Based on the above scheme, the support arm is provided with a support base and a roller rotatably mounted on the support base, and the roller abuts against the upper end of the support frame.

[0009] Based on the above scheme, the bending guide mechanism includes a first guide frame protruding from the first frame towards the second frame and a second guide frame disposed outside the first guide frame, and an arc-shaped bending channel for conveying pipe material is defined between the first guide frame and the second guide frame.

[0010] Based on the above scheme, the bending guide mechanism further includes a plurality of rotatable first guide rollers, which are spaced apart along the arc-shaped bending channel. One end of the first guide roller is connected to the side of the first frame near the first guide frame, and the other end of the first guide roller approaches the arc-shaped bending channel. The first frame is provided with a plurality of rotatable second guide rollers, which are arranged transversely to the rotating rollers. The second guide rollers are used to support the pipe material after it leaves the arc-shaped bending channel.

[0011] Based on the above scheme, the first guide frame includes a plurality of first baffles and a plurality of first transmission rollers arranged at intervals, and the second guide frame includes a plurality of second baffles and a plurality of second transmission rollers arranged at intervals, wherein the first transmission rollers and the second transmission rollers are arranged along the axial direction of the rotating rollers.

[0012] Based on the above scheme, the rotating component includes a second motor and a second sprocket driven by the second motor. The second sprocket is located at one end of the rotating roller that extends out of the second frame. The winding frame is provided with two rotating rollers, and the second sprockets on the two rotating rollers are driven by a second chain.

[0013] Based on the above scheme, the first frame is provided with a pipe clamping mechanism on the front side of the bending guide mechanism to guide the pipe material to be conveyed into the bending guide mechanism. The pipe clamping mechanism includes a clamping frame, a pipe clamping member disposed on the clamping frame for clamping the pipe material, and a lifting mechanism for controlling the height position of the pipe clamping member.

[0014] Based on the above scheme, the pipe clamping component includes a clamping seat connected to the clamping frame, a first cylinder mounted on the clamping seat, and two clamping plates slidably mounted on the clamping seat. A transmission rod is hinged to the upper end of the clamping plate, and the transmission rod is hinged to the output end of the first cylinder to drive the two clamping plates to move closer to each other or further away from each other when the first cylinder is activated. The lifting mechanism includes a second cylinder and a lifting seat slidably mounted on the clamping frame. The pipe clamping component is mounted on the lifting seat, and the output end of the second cylinder is connected to the lifting seat.

[0015] The beneficial effects of this invention are:

[0016] The winding device disclosed in this invention has multiple winding mechanisms for winding tube material. When the winding mechanism is located at the loading station, it can wind the tube material; when the winding mechanism is located at the intermediate processing station, it can perform intermediate processing on the coil material located on the winding mechanism, such as head forming; when the winding mechanism is located at the unloading station, it can remove the coil material from the winding mechanism; when the winding mechanism is located at the preparation station, it is in an unloaded state waiting for loading, and slides to the loading station for loading after the winding mechanism at the loading station leaves.

[0017] The time required for unloading is less than that for loading. After the winding mechanism at the loading station completes the winding, all winding mechanisms can slide relative to the support frame and move to the next station, so that the next round of winding can start immediately, thereby improving winding efficiency. Furthermore, the winding and unloading are carried out at different processing stations, which are located on both sides of the support frame. The winding mechanisms at the two processing stations can operate independently without interfering with each other.

[0018] The winding device is typically located at the rear of the equipment used to convey the tubing. During winding, the tubing is fed from the conveying equipment toward the winding device. A bending guide mechanism guides the tubing toward the rotating roller and gradually bends it during transport, allowing it to wind onto the roller. A rotating component drives the roller to rotate, making it easier for the tubing to wind onto the roller and reducing relative friction between the roller and the tubing, thus minimizing wear on the surfaces of both.

[0019] As the number of windings on the rotating roller increases, once the number of windings reaches a certain level, the power of the conveying device to drive the pipe becomes insufficient, causing the pipe to be unable to continue winding onto the rotating roller. Meanwhile, the pipe behind continues to be conveyed forward, causing the pipe to bend. The rotating component can provide additional power, using the friction between the rotating roller and the pipe to drive the pipe to be conveyed, ensuring that the pipe can be smoothly wound onto the rotating roller.

[0020] Furthermore, the upper end of the support frame is provided with a main shaft, and the winding mechanism includes a winding frame. Support arms fixedly connected to the winding frame are rotatably mounted on the main shaft. Multiple support arms of the winding frames are coaxially arranged and independent of each other. A first chain is embedded in the support frame, and a first sprocket meshing with the first chain and a first motor driving the first sprocket to rotate are provided on the support arm. The first motor can drive the first sprocket to rotate. Since the first chain is fixed to the support frame, when the first sprocket rotates, it moves along the first chain through meshing transmission with the first chain, causing the support arm and the winding mechanism to rotate relative to the support frame. The transmission relationship between the first chain and the first sprocket is stable and slippage will not occur.

[0021] Furthermore, the winding device also includes a distance maintaining member for maintaining the distance between two connected winding mechanisms. The distance maintaining member is a push rod disposed on the support arm, and the push rods on adjacent support arms can abut against each other when the winding mechanism slides relative to the support frame. The distance maintaining member can prevent the tube material on the two winding mechanisms from colliding due to excessively close spacing, and also prevents the center of gravity of the entire winding device from deviating too far from the center of the support frame, ensuring the stability of the winding device. As the winding mechanism and support arm rotate, the two support arms gradually approach each other, causing the push rods to contact each other. This not only alerts the tube winding device that the current spacing between the two winding mechanisms is too close, but also limits the two winding mechanisms from further approaching each other.

[0022] Furthermore, the support arm is provided with a support base and a roller rotatably mounted on the support base, the roller abutting against the upper end of the support frame. The roller can rotate when the support arm rotates relative to the support frame, and can maintain a distance between the support arm and the support frame to avoid wear between the support arm and the support frame, thereby reducing the power required to drive the support arm and the winding mechanism to rotate relative to the support frame.

[0023] Furthermore, the bending guiding mechanism includes a first guide frame protruding from the first frame towards the second frame and a second guide frame disposed outside the first guide frame. The first guide frame and the second guide frame define an arc-shaped bending channel for conveying the tubing. When the tubing is conveyed to the bending guiding mechanism, it contacts the protruding first or second guide frame, causing the tubing to be blocked and unable to continue being conveyed horizontally. Instead, it is conveyed along the arc-shaped bending channel. As the tubing continuously enters the arc-shaped bending channel, it gradually bends, allowing it to wrap around the rotating roller after leaving the arc-shaped bending channel.

[0024] Furthermore, the bending guiding mechanism also includes multiple rotatable first guide rollers, which are spaced apart along the arc-shaped bending channel. One end of each first guide roller is connected to the side of the first frame near the first guide frame, and the other end of each first guide roller approaches the arc-shaped bending channel. Multiple rotatable second guide rollers are provided on the first frame, arranged transversely to the rotating roller. These second guide rollers support the tube material after it leaves the arc-shaped bending channel. During the winding process on the rotating roller, the tube material continuously moves along its axial direction, thus leaving the arc-shaped bending channel. The first guide rollers can block the tube material, limiting its deviation from the arc-shaped bending channel towards the side of the first frame near the first guide frame, preventing the inner diameter of the wound material from becoming too small. The first guide rollers can rotate under the influence of the tube material, reducing wear on the tube material. The tube has already been bent after passing through the arc-shaped bending channel, so it is not necessary to arrange bending guide mechanisms on the entire first frame. The second guide roller can prevent the tube from directly contacting the first frame, and at the same time, the second guide roller can rotate under the drive of the tube, reducing the wear of the tube.

[0025] Furthermore, the first guide frame includes a plurality of first baffles and a plurality of first drive rollers spaced apart, and the second guide frame includes a plurality of second baffles and a plurality of second drive rollers spaced apart. The first drive rollers and the second drive rollers are arranged along the axial direction of the rotating rollers. The first baffles and the second baffles can block the tube material and keep it within the arc-shaped bending channel, so that the tube material gradually bends during the conveying process. The first drive rollers and the second drive rollers can contact the tube material and rotate during the conveying of the tube material along the arc-shaped bending channel, reducing the wear of the tube material within the arc-shaped bending channel and improving the smoothness of the tube material's conveying within the arc-shaped bending channel.

[0026] Furthermore, the rotating component includes a second motor and a second sprocket driven by the second motor. The second sprocket is located at the end of the rotating roller that extends out of the second frame. The winding frame has two rotating rollers, and the second sprockets on the two rotating rollers are driven by a second chain. By setting two rotating rollers, the support effect on the tube is improved. The weight of the tube can be distributed on the two rotating rollers, reducing the pressure on the contact surface between the tube and the rotating rollers, thus providing better protection for the tube. In addition, both rotating rollers can rotate, improving the smoothness of the tube transmission. The second sprocket is located outside the second frame to prevent the tube from contacting the second sprocket and affecting the transmission cooperation between the rotating component and the rotating rollers, and also to prevent the tube from being damaged by the rotating component. Power transmission via the second chain and second sprocket avoids slippage.

[0027] Furthermore, a pipe clamping mechanism is provided on the first frame, located in front of the bending guide mechanism, to guide the pipe material towards the bending guide mechanism. The pipe clamping mechanism includes a clamping frame, pipe clamping components disposed on the clamping frame for clamping the pipe material, and a lifting mechanism for controlling the height of the pipe clamping components. When the pipe material is conveyed to the bending guide mechanism, the pipe clamping mechanism can guide the pipe material towards the entrance position of the bending guide mechanism, thereby achieving automatic feeding without manual operation and improving the pipe material processing efficiency. The pipe clamping mechanism uses the pipe clamping components to clamp the pipe material, restricting its vertical displacement and ensuring alignment with the entrance position of the bending guide mechanism. The lifting mechanism controls the lifting movement of the pipe clamping components to align the pipe material. Compared to manual operation, guided by the pipe clamping mechanism, the pipe material can enter the bending guide mechanism precisely.

[0028] Furthermore, the pipe clamping component includes a clamping seat connected to the clamping frame, a first cylinder mounted on the clamping seat, and two clamping plates slidably mounted on the clamping seat. A transmission rod is hinged to the upper end of each clamping plate, and the transmission rod is hinged to the output end of the first cylinder to drive the two clamping plates closer to or further away from each other when the first cylinder is actuated. The lifting mechanism includes a second cylinder and a lifting seat slidably mounted on the clamping frame. The pipe clamping component is mounted on the lifting seat, and the output end of the second cylinder is connected to the lifting seat. When the first cylinder is actuated, its push rod can extend and retract to rotate the transmission rod, thereby pulling the clamping plates to slide relative to the clamping seat. When the two clamping plates are close together, the pipe can be clamped; when the two clamping plates are far apart, the pipe can be released, thus not affecting the pipe's transport and preventing wear on the pipe surface due to contact with the clamping plates. The pipe clamping component is installed on the lifting seat to move up and down synchronously with the lifting seat. The second cylinder can drive the lifting seat to move up and down relative to the clamping frame to adjust the height position of the pipe clamping component.

Detailed Implementation Methods

[0046] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0047] The terms "exemplary" and "some embodiments" used below are meant to be "used as examples, embodiments, or illustrations," and any embodiment described as "exemplary" is not necessarily to be construed as superior to or better than other embodiments. Numerous specific details are set forth in the following detailed description to better illustrate the invention, and those skilled in the art will understand that this disclosure can be practiced without certain specific details.

[0048] Reference Figures 1 to 9 The present invention discloses a multi-station winding device, including a support frame 100 and a winding mechanism disposed on the support frame 100 for winding tube material. The upper end of the support frame 100 is provided with multiple processing stations along the circumferential direction. The multiple processing stations include a feeding station, an intermediate processing station, a feeding station, and a preparation station. Each processing station is provided with a winding mechanism, which can slide relative to the support frame 100 in the circumferential direction to switch between processing stations.

[0049] The winding device disclosed in this invention has multiple winding mechanisms for winding tube material. When the winding mechanism is located at the loading station, it can wind the tube material; when the winding mechanism is located at the intermediate processing station, it can perform intermediate processing on the coil material located on the winding mechanism, such as head forming; when the winding mechanism is located at the unloading station, it can remove the coil material from the winding mechanism; when the winding mechanism is located at the preparation station, it is in an unloaded state waiting for loading, and slides to the loading station for loading after the winding mechanism at the loading station leaves.

[0050] The time required for unloading is less than that for loading. After the winding mechanism at the loading station completes the winding, all winding mechanisms can slide relative to the support frame 100 and move to the next station, so that the next round of winding can start immediately, thereby improving winding efficiency. Furthermore, the winding and unloading are carried out at different processing stations, which are located on both sides of the support frame 100. The winding mechanisms at the two processing stations can operate independently and will not interfere with each other.

[0051] The winding device includes a winding frame 200 and a rotating roller 300 rotatably mounted on the winding frame 200 for winding tube material. The winding frame 200 includes a crossbeam 210, a first frame 220 disposed at one end of the crossbeam 210 and a second frame 230 disposed at the other end of the crossbeam 210. The first frame 220 is provided with a bending guide mechanism for bending and guiding the tube material to wrap around the rotating roller 300, and the second frame 230 is provided with a rotating component for driving the rotating roller 300 to rotate.

[0052] The winding device is typically located behind the equipment used for conveying tubular material. During winding, the tubular material is conveyed from the conveying equipment towards the winding device. A bending guide mechanism guides the tubular material towards the rotating roller 300, gradually bending it during the conveying process so that it can be wound onto the rotating roller 300. A rotating component drives the rotating roller 300 to rotate, making it easier for the tubular material to wind onto the rotating roller 300 and reducing relative friction between the rotating roller 300 and the tubular material, thus preventing wear on the surfaces of the tubular material and the rotating roller 300.

[0053] As the number of windings on the rotating roller 300 increases, when the number of windings increases to a certain extent, the power of the conveying device to drive the pipe becomes insufficient, which will cause the pipe to be unable to continue winding onto the rotating roller 300. Meanwhile, the pipe on the rear side continues to be conveyed forward, causing the pipe to bend. The rotating component can provide additional power, and drive the pipe to be conveyed through the friction between the rotating roller 300 and the pipe, so as to ensure that the pipe can be smoothly wound onto the rotating roller 300.

[0054] The winding frame 200 is equipped with two rotating rollers 300, which improves the support effect on the tube material. The weight of the tube material can be distributed on the two rotating rollers 300, reducing the pressure on the contact surface between the tube material and the rotating rollers 300, thus providing better protection for the tube material. In addition, both rotating rollers 300 can rotate, improving the smoothness of tube material transmission. The two rotating rollers 300 are set on the same horizontal plane, providing better support for the tube material, and the weight of the tube material can be evenly distributed on the two rotating rollers 300. The surface of the rotating rollers 300 is provided with spirally distributed tube material guide grooves 310. The tube material guide grooves 310 guide the tube material, so that the tube material moves gradually along the axial direction of the rotating rollers 300 while rotating circumferentially, thereby reducing the wear caused by the tube material moving along the axial direction of the rotating rollers 300. At the same time, a certain distance is maintained between the tube materials in adjacent guide grooves to avoid mutual compression between the tube materials.

[0055] The upper end of the support frame 100 is provided with a main shaft 110, on which a support arm 120 fixedly connected to the crossbeam 210 is rotatably mounted. The support arms 120 of multiple winding frames 200 are coaxially arranged and independent of each other. Since the winding mechanism is heavy, and its weight will further increase after winding the tube material, in order to reduce the power required to rotate the winding mechanism and reduce the overall power consumption of the equipment, the support arm 120 is provided with a support seat 130 and a roller 140 rotatably mounted on the support seat 130. The roller 140 abuts against the upper end of the support frame 100. The roller 140 can rotate when the support arm 120 rotates relative to the support frame 100, and can maintain a distance between the support arm 120 and the support frame 100 to avoid wear between the support arm 120 and the support frame 100, thereby reducing the power required to drive the support arm 120 and the winding mechanism to rotate relative to the support frame 100.

[0056] Because the winding mechanism is quite heavy, typical drive devices are prone to slippage when driving it from a stationary state to a moving state. This application employs a transmission method using a first sprocket 150 and a first chain 160. The first chain 160 is mounted on the support frame 100, and the support arm 120 has a first sprocket 150 meshing with the first chain 160 and a first motor 170 driving the first sprocket 150 to rotate. Since the first chain 160 is fixed to the support frame 100, when the first sprocket 150 rotates, it moves along the first chain 160 through the meshing transmission with it, causing the support arm 120 and the winding mechanism to rotate relative to the support frame 100. The transmission relationship between the first chain 160 and the first sprocket 150 is stable and slippage is prevented. In addition, when the winding mechanism moves from a moving state to a stationary state, it has a large inertial force. Through the transmission of the first sprocket 150 and the first chain 160, the winding mechanism can quickly enter a stationary state without slipping relative to the support frame 100.

[0057] Alternatively, transmission can be achieved using a gear and rack system. An external gear ring is mounted on the support frame 100, and a gear meshing with the external gear ring and a motor driving the gear are mounted on the support arm 120. The motor drives the gear to rotate, and the gear, through meshing with the external gear ring, moves the support arm 120 and the winding mechanism along the external gear ring.

[0058] A rotating roller 300 is positioned at the upper end of the first frame 220, and a bending guide mechanism is positioned at the lower end of the first frame 220, enabling the tube to bend during upward conveying. Specifically, the bending guide mechanism includes a first guide frame 400 protruding from the first frame 220 toward the second frame 230 and a second guide frame 410 positioned outside the first guide frame 400. The first guide frame 400 and the second guide frame 410 define an arc-shaped bending channel 420 for tube conveying. When the tube is conveyed to the bending guide mechanism, it contacts the protruding first guide frame 400 or second guide frame 410, causing the tube to be blocked and unable to continue horizontally conveyed, instead being conveyed along the arc-shaped bending channel 420. As the tube continuously enters the arc-shaped bending channel 420, it gradually bends, allowing it to wrap around the rotating roller 300 after leaving the arc-shaped bending channel 420.

[0059] To reduce wear on the tube during bending, the first guide frame 400 includes multiple first baffles 401 and multiple first drive rollers 402 spaced apart, and the second guide frame 410 includes multiple second baffles 411 and multiple second drive rollers 412 spaced apart. The first drive rollers 402 and the second drive rollers 412 are arranged along the axial direction of the rotating roller 300. The first baffles 401 and the second baffles 411 can block the tube and keep it within the arc-shaped bending channel 420, so that the tube gradually bends during the conveying process. The first drive rollers 402 and the second drive rollers 412 can contact the tube and rotate during the conveying process along the arc-shaped bending channel 420, reducing wear on the tube within the arc-shaped bending channel 420 and improving the smoothness of the tube conveying in the arc-shaped bending channel 420.

[0060] The arc-shaped bending channel 420 has a limited depth. During the winding process on the rotating roller 300, the tube material will continuously move along the axial direction of the tube material, thereby leaving the arc-shaped bending channel 420. The bending guiding mechanism also includes multiple rotatable first guide rollers 430. The multiple first guide rollers 430 are spaced apart along the arc-shaped bending channel 420. One end of the first guide roller 430 is connected to the side of the first frame 220 near the first guide frame 400, and the other end of the first guide roller 430 approaches the arc-shaped bending channel 420. The first guide roller 430 can block the tube material and limit the tube material from deviating from the arc-shaped bending channel 420 to the side of the first frame 220 near the first guide frame 400, resulting in the inner diameter of the wound material being too small after winding. The first guide roller 430 can rotate under the drive of the tube material to reduce the wear on the tube material.

[0061] As the tubing is conveyed, it leaves the curved bending channel 420 and approaches the rotating roller 300. At this point, the tubing has already been bent, so it is not necessary to arrange bending guide mechanisms on the entire first frame 220. The first frame 220 is provided with multiple rotatable second guide rollers 440. The second guide rollers 440 are arranged transversely to the rotating roller 300. The second guide rollers 440 are used to support the tubing after it leaves the curved bending channel 420, which can prevent the tubing from directly contacting the first frame 220. At the same time, the second guide rollers 440 can rotate under the drive of the tubing, reducing the wear of the tubing.

[0062] The tubing needs to enter the curved bending channel 420 before it can be bent. However, the opening of the curved bending channel 420 is fixed. The tubing is soft and easily deformed during rolling, and the end of the tubing deviates downwards after leaving the conveying equipment, making it impossible to align with the bending guide mechanism. A tubing clamping mechanism is provided on the first frame 220, located in front of the entrance of the curved bending channel 420, to guide the tubing towards the bending guide mechanism. The tubing clamping mechanism includes a clamping frame 500, a tubing clamping member 510 disposed on the clamping frame 500 for clamping the tubing, and a lifting mechanism 520 for controlling the height of the tubing clamping member 510. The tubing clamping mechanism can automatically feed the tubing towards the entrance of the curved bending channel 420 during transport, eliminating the need for manual operation and improving the processing efficiency of the tubing.

[0063] The pipe clamping mechanism uses pipe clamping parts 510 to hold the pipe, restricting its vertical displacement and aligning it with the entrance of the curved bending channel 420. The lifting mechanism 520 controls the lifting movement of the pipe clamping parts 510 to align the pipe. Compared to manual operation, the pipe clamping mechanism guides the pipe, allowing it to enter the curved bending channel 420 precisely.

[0064] The pipe clamping component 510 includes a clamping seat 511 connected to the clamping frame 500, a first cylinder 512 mounted on the clamping seat 511, and two clamping plates 513 slidably mounted on the clamping seat 511. A transmission rod 514 is hinged to the upper end of each clamping plate 513. The transmission rod 514 is hinged to the push rod of the first cylinder 512, so that when the first cylinder 512 is activated, it drives the two clamping plates 513 to move closer or further apart. When the first cylinder 512 is activated, its push rod can extend and retract, thereby causing the transmission rod 514 to rotate, thus pulling the clamping plates 513 to slide relative to the clamping seat 511. When the two clamping plates 513 are close together, they can clamp the pipe; when the two clamping plates 513 are far apart, they can release the pipe, thus not affecting the pipe's transport and preventing the pipe from contacting the clamping plates 513 and causing wear on the pipe surface.

[0065] To prevent the pipe clamping component 510 from deforming the pipe when clamping it, the two clamping plates 513 have recessed pipe clamping grooves 515 on their opposite sides. The pipe clamping grooves 515 on the two clamping plates 513 form a pipe clamping channel 516. The center line of the pipe clamping channel 516 and the entrance center of the arc-shaped bending channel 420 are located on the same vertical plane. When the two clamping plates 513 approach each other, the recessed pipe clamping grooves 515 can form a pipe clamping channel 516 to accommodate the pipe, thereby vertically limiting the pipe. With the action of the lifting mechanism 520, the pipe can move up and down synchronously with the pipe clamping component 510, so that there is no large relative force between the clamping plate 513 and the pipe, thus avoiding the pipe being clamped and deformed.

[0066] The lifting mechanism 520 includes a second cylinder 521 and a lifting seat 522 slidably mounted on the clamping frame 500. A pipe clamping component 510 is mounted on the lifting seat 522, and the push rod of the second cylinder 521 is connected to the lifting seat 522. The pipe clamping component 510 is mounted on the lifting seat 522 to move synchronously with it. The second cylinder 521 can drive the lifting seat 522 to move relative to the clamping frame 500, thereby adjusting the height position of the pipe clamping component 510. The clamping frame 500 is provided with two slide rails, and the lifting seat 522 slides along these rails. Driven by the second cylinder 521, the lifting seat 522 can slide along the slide rails. By providing two slide rails, the lifting seat 522 can be limited, thus preventing the pipe clamping component 510 from shaking and ensuring that the pipe can smoothly enter the arc-shaped bending channel 420 under the guidance of the pipe clamping mechanism.

[0067] The pipe clamping mechanism and the bending guide mechanism are respectively located at both ends of the first frame 220 along the axial direction of the pipe. The first frame 220 is roughly C-shaped, and its middle position is connected to the crossbeam 210. The bending guide mechanism is located at one end of the first frame 220 and arranged along its side. When the pipe leaves the conveying equipment and is conveyed to the bending guide mechanism, it still needs to be conveyed a certain distance after passing the pipe clamping mechanism before entering the arc-shaped bending channel 420. During this process, the pipe clamping mechanism has sufficient time to clamp the pipe and adjust its vertical position. As the pipe leaves the conveying equipment, it gradually shifts downward as its length extends beyond the equipment. The distance between the pipe clamping mechanism and the conveying equipment is less than the distance between the entrance of the curved bending channel 420 and the conveying equipment. The large gap between the conveying equipment and the entrance of the curved bending channel 420 results in a large offset of the pipe. The pipe clamping mechanism can clamp the pipe before the offset becomes too large to prevent downward deformation.

[0068] A certain distance needs to be maintained between the multiple winding mechanisms on the support frame 100 to avoid collisions between the tubes on two winding mechanisms due to excessively close spacing. The tube winding device also includes a distance maintaining member to maintain the distance between two connected winding mechanisms at all times. In addition, this also prevents the center of gravity of the entire tube winding device from deviating too far from the center of the support frame 100, ensuring the stability of the tube winding device.

[0069] Preferably, the distance maintaining element is a push rod 180 mounted on the support arm 120. The push rods 180 on two adjacent support arms 120 can abut against each other when the winding mechanism slides relative to the support frame 100. As the winding mechanism and support arm 120 rotate, the two support arms 120 gradually approach each other, causing the push rods 180 to contact each other. This not only alerts the pipe winding device that the distance between the two winding mechanisms is too close, but also prevents the two winding mechanisms from further approaching each other. A collision sensor can also be mounted on the support arm 120, which is triggered when the two push rods 180 abut against each other. Since the support arm 120 is engaged with the first chain 160 on the support frame 100 via the first sprocket 150, when the two push rods 180 abut against each other, the moving support arm 120 cannot push the stationary support arm 120.

[0070] In addition, the distance holding element can also be a sensor, which can be set with trigger conditions to generate a corresponding signal after the distance between the two support arms reaches a set range.

[0071] The sensor can be a distance sensor mounted on the support arm. This distance sensor detects the distance between adjacent support arms and can alert the tube winding device when the distance between two support arms is too small. This allows the winding mechanism to adjust its rotation speed or stop its positional change before the two winding mechanisms collide. For example, if the winding mechanism at the current station is still working while the winding mechanism at the previous station is moving towards the current station, the distance sensor can stop the movement of the winding mechanism at the previous station before the two winding mechanisms collide, thus avoiding interference with the normal operation of the winding mechanism at the current station.

[0072] The sensor can also be an angle sensor installed on the winding mechanism or support arm. The angle sensor is used to detect the angle of rotation of the winding mechanism or support arm relative to the support frame. Each winding mechanism or support arm is equipped with an angle sensor, so that the angle of rotation of each winding mechanism relative to the support frame can be known, thereby determining the current position of each winding mechanism and controlling the spacing between them.

[0073] The rotating component mentioned above includes a second motor 240 and a second sprocket 250 driven by the second motor 240. One end of the rotating roller 300 extends out of the second frame 230. The second sprocket 250 is located at the end of the rotating roller 300 that extends out of the second frame 230 to prevent the pipe material from contacting the second sprocket 250 and affecting the transmission between the rotating component and the rotating roller 300. It also prevents the pipe material from being damaged by the rotating component. The second sprockets 250 on the two rotating rollers 300 are driven by chains. The rotating component also includes two gears mounted on the drive shaft of the second motor 240. One gear is driven by one of the second sprockets 250 through a second chain 260, and the other gear is driven by the other second sprocket 250 through a second chain 260. Power is transmitted through the second chain 260 and the second sprocket 250 to avoid slippage.

Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
