Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a tube reel module. Background Technology

[0002] Tube winding equipment is a type of equipment used to automatically roll flexible materials such as sheets or fabrics into tubular products. To improve winding accuracy, some equipment has introduced a correction device. Its working process is as follows: first, a robot arm picks up the sheet and moves it to the correction device for position correction. Then, the robot arm moves the corrected sheet to the feeding platform and finally feeds it into the tube winding mechanism to complete the winding.

[0003] However, the above-mentioned operation method of repeatedly picking up and placing materials between the correction device and the feeding platform by a robotic arm not only increases the production cycle time and reduces the overall efficiency, but also easily causes new positional deviations in the already corrected sheet material due to mechanical positioning errors or movement deviations during the secondary picking and placing process, affecting the dimensional accuracy and product quality of the final rolled tube. Summary of the Invention

[0007] As an optional technical solution, the tube cavity is configured as a circular hole structure extending along the second direction; The upper part of the tube cavity is provided with a film inlet channel communicating with it, the film inlet channel extends along the first direction and communicates with the top of the tube cavity; The tube cavity has a feeding port at one end in the axial direction for the mandrel to pass through; The side wall of the tube support plate is provided with several welding clearance openings that communicate with the tube cavity to avoid the welding components.

[0008] As an optional technical solution, a positioning detection element is installed at the end of the tube cavity opposite to the feed port. The positioning detection element is used to detect the depth to which the mandrel is inserted into the tube cavity along the second direction.

[0009] As an optional technical solution, the feeding mechanism includes a feeding rotary drive and a feeding roller. The feeding roller is rotatably arranged around an axis in the second direction. The feeding roller is connected to the rotation shaft of the feeding rotary drive.

The support plate can also rotate around the vertical axis, thus achieving precise adjustment and centering correction of the workpiece's position. After correction, the feeding mechanism directly and smoothly transports the positioned workpiece along the first direction to the tube winding station of the tube winding device. This integrated structure achieves continuous operation of correction and feeding, dynamically eliminating the intermediate step of secondary material handling between the support plate and the tube winding device in traditional equipment. This not only significantly shortens the material flow path and cycle time, improving the overall efficiency of the tube winding operation, but also avoids mechanical positioning errors or movement deviations that may be caused by secondary handling operations, fundamentally eliminating the generation of secondary deviations and effectively ensuring the dimensional accuracy and forming quality of the rolled tube products.

[0022] Embodiments of the present invention are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In the field of tube rolling technology, flexible materials such as sheets or fabrics are typically rolled into tubular products using automated tube rolling equipment. Typical tube rolling equipment usually includes modules such as feeding device, rolling device, welding device and unloading device, which can realize continuous production from rolling to cutting.

[0024] Currently, to improve winding accuracy, some equipment has introduced a web-correcting device. Its workflow is as follows: first, a robotic arm picks up the sheet material and moves it to the web-correcting device for position adjustment; then, the robotic arm transfers the corrected sheet material to the feeding platform, and finally, it is fed into the winding mechanism to complete the winding process. Its disadvantages are: First, the need for robotic arms to perform multiple pick-and-place operations between the correction device and the feeding platform increases production cycle time, resulting in a decrease in overall efficiency. Secondly, during the secondary handling process, mechanical positioning errors or movement deviations can easily cause new positional deviations in the already corrected sheet material, affecting the dimensional accuracy and product quality of the final rolled tube.

[0025] To address the aforementioned technical problems, this embodiment proposes a deviation correction feeding device, which aims to resolve the problems caused by the need for multiple pick-and-place operations by a robotic arm in conventional tube winding equipment.

[0026] Therefore, the technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 12 As shown, this embodiment provides a tube winding module, which includes a correction feeding device 100 and a tube winding device 200. The correction feeding device 100 includes a correction platform 120, which is mounted on a bottom mounting plate 160. A support plate 110 is provided on the correction platform 120 for supporting and fixing the workpiece 1000 to be wound. The tube winding device 200 is arranged adjacent to the correction platform 120 in a horizontal first direction. The tube winding device 200 is used to wind the workpiece 1000 into a tubular component. The workpiece 1000 is specifically a sheet, cloth, or film material such as fiberglass cloth.

[0027] For further details, please refer to Figures 1 to 3 The correction platform 120 is also equipped with a feeding mechanism 130, which is located between the support plate 110 and the tube winding device 200. The feeding mechanism 130 can drive the workpiece 1000 to be wound on the support plate 110 to be translated along the first direction to the tube winding station on the tube winding device 200. Under the action of the correction platform 120, the support plate 110 and the feeding mechanism 130 can be translated synchronously along the first direction and the horizontal second direction. The first direction is perpendicular to the second direction, and the support plate 110 can also rotate around the vertical axis. It can be understood that the first direction is the X direction in the figure, and the second direction is the Y direction in the figure.

[0028] Specifically, the tube winding module provided in this embodiment integrates the feeding mechanism 130 into the correction platform 120, enabling the support plate 110 and the feeding mechanism 130 to move synchronously along the first and second directions. Furthermore, the support plate 110 can rotate around the vertical axis, thereby achieving precise adjustment and centering correction of the position of the workpiece 1000 to be wound. After correction, the feeding mechanism 130 directly drives the positioned workpiece 1000 to be wound smoothly transported along the first direction to the winding station of the tube winding device 200. This integrated structure realizes continuous operation of correction and feeding, dynamically eliminating the intermediate transfer link of the robot arm performing secondary material handling between the support plate 110 and the tube winding device 200 in traditional equipment. This not only significantly shortens the material flow path and cycle time, improving the overall efficiency of the tube winding operation, but also avoids mechanical positioning errors or movement deviations that may be caused by secondary handling operations, fundamentally eliminating the generation of secondary deviations and effectively ensuring the dimensional accuracy and forming quality of the rolled tube products.

[0029] For example, the feeding mechanism 130 includes a feeding rotary drive 131 and a feeding roller 132. The feeding roller 132 is connected to the rotating shaft of the feeding rotary drive 131 via a coupling. The feeding rotary drive 131 can drive the feeding roller 132 to rotate around its axis in a second direction, thereby driving the fabric to be rolled on the material placement plate to be conveyed out in a first direction. Since the feeding roller 132 is directly connected to the rotating shaft of the feeding rotary drive 131 via a coupling, when the feeding mechanism 130 moves away from the winding device 200 in the first direction to tighten the fabric to be rolled 1000, the feeding rotary drive 131 can detect the torque of the winding tube in real time and accurately. Compared with the design of indirectly connecting the feeding rotary drive 131 through intermediate structural components such as a synchronous belt, the torque detection accuracy is higher and more reliable.

[0030] For the structure of the correction platform 120, please refer to... Figures 3 to 5The correction platform 120 includes a first translation module 121, a second translation module 122, and a rotation module 123. The first translation module 121 is fixedly installed on the upper surface of the bottom mounting plate 160, and the power output end of the first translation module 121 can reciprocate along a first direction. The body of the second translation module 122 is installed on the power output end of the first translation module 121, and the power output end of the second translation module 122 can reciprocate along a second direction. The rotation module 123 is installed on the power output end of the second translation module 122, and the power output end of the rotation module 123 can rotate around a vertical axis. The bearing plate 110 is installed on the power output end of the rotation module 123, and the feeding mechanism 130 is installed on the power output end of the second translation module 122. As can be seen, under the drive of the first translation module 121 and the second translation module 122, the carrier plate 110 and the feeding mechanism 130 can be translated synchronously along the first direction and the second direction. During the horizontal position correction process, the relative positions of the carrier plate 110 and the feeding mechanism 130 remain unchanged. When the rotation module 123 corrects the horizontal orientation of the workpiece 1000 to be rolled, the carrier plate 110 rotates relative to the feeding mechanism 130, so that the side of the workpiece 1000 to be rolled is strictly parallel to the first direction, thereby ensuring that the direction in which the feeding roller 132 transmits the workpiece 1000 to be rolled is the first direction, and ensuring the accuracy of subsequent tube winding.

[0031] For example, the first translation module 121 adopts an electric linear slide table in the prior art. Specifically, the first translation module 121 adopts a high-precision linear slide table, whose driver is a servo motor, whose transmission structure is a ball screw, and whose guide structure is a linear guide or a cross roller guide. The control accuracy of translation direction and distance is fully ensured from the three parts of driving, transmission and guiding.

[0032] For example, the second translation module 122 adopts an electric linear slide, which is a conventional electric linear slide. Specifically, the second translation module 122 adopts a high-precision linear slide, whose driver is a servo motor, whose transmission structure is a ball screw, and whose guide structure is a linear guide or a cross roller guide. The control accuracy of translation direction and distance is fully ensured from the three parts of driving, transmission and guiding.

[0033] For example, the rotary module 123 adopts an electric rotary slide in the prior art, specifically a high-precision rotary table such as a worm gear drive rotary table or a ball screw drive rotary table. Its driver is a servo motor, the transmission structure is a worm gear or ball screw, and the guide structure is a linear guide or a cross roller guide. The control accuracy of the rotation angle is fully ensured from the three parts of driving, transmission and guiding.

[0034] For example, regarding the connection structure between the various modules of the correction platform 120, please refer to... Figures 3 to 5The second translation module 122 has a correction connecting plate 124 installed on its power output end. The bodies of the feeding mechanism 130 and the rotating module 123 are respectively installed on the correction connecting plate 124 by fastening screws and other structures. The first translation module 121 has a translation connecting plate 125 installed on its power output end. The body of the second translation module 122 is installed on the translation connecting plate 125 by fastening screws and other structures.

[0035] To secure the roll 1000 on the support plate 110, please refer to... Figure 3 , Figure 5 and Figure 6 The support plate 110 is provided with multiple on-plate adsorption holes 111 and multiple first air extraction holes 112. The multiple on-plate adsorption holes 111 are distributed on the upper surface of the support plate 110. The support plate 110 is provided with multiple first air extraction holes 112 on two opposite sides in the second direction. The on-plate adsorption holes 111 and the first air extraction holes 112 are connected through air channels provided in the support plate 110. The first air extraction holes 112 are used to connect to an external air extraction device. After the workpiece 1000 to be rolled is placed on the support plate 110, the air extraction device extracts air from the air channels through the multiple first air extraction holes 112 to form a negative pressure, so as to adsorb and fix the flat and unfolded workpiece 1000 through the multiple on-plate adsorption holes 111.

[0036] For example, multiple adsorption holes 111 on the plate are distributed in a matrix on the upper surface of the support plate 110 to achieve uniform adsorption of multiple areas of the roll 1000, improve adsorption uniformity and adsorption stability, and ensure that the roll 1000 can maintain a stable spreading state on the support plate 110.

[0037] To secure the workpiece 1000 on the feeding roller 132 so that the feeding mechanism 130 can pull the workpiece 1000 in reverse to tighten it, please refer to... Figure 5 and Figure 7The feeding roller 132 has a cavity inside, and multiple suction holes 1321 are provided on the outer circumferential surface of the feeding roller 132. The multiple suction holes 1321 are arranged along the axial direction of the feeding roller 132. The end of the feeding roller 132 is provided with a second suction hole 1322. The multiple suction holes 1321 and the second suction hole 1322 are both connected to the cavity. The second suction hole 1322 is used to connect an external suction device. When the correction platform 120 performs the correction action, the front end of the workpiece 1000 to be rolled is placed above the feeding roller 132 in the first direction. At this time, the air extraction device does not extract the air inside the feeding roller 132. After the correction action and the feeding action are completed, and the first translation module 121 drives the bearing plate 110 and the feeding mechanism 130 to move away from the winding tube device 200 in the first direction to tighten the workpiece 1000, the air extraction device extracts the air inside the cavity of the feeding roller 132 through the second air extraction hole 1322 to form a negative pressure, so as to adsorb the workpiece 1000 through the multiple adsorption holes 1321 on the cylinder, so that the tension of the workpiece 1000 can be transmitted to the feeding roller 132 and the feeding rotation drive 131 in sequence.

[0038] For example, the feeding rotary drive 131 is preferably a torque motor, which can output power with constant torque and has the characteristics of low speed and high torque. In some embodiments, the feeding rotary drive 131 may also adopt other types of servo motors or other rotary drive elements.

[0039] For example, please refer to Figures 3 to 5 The feeding mechanism 130 also includes a feeding bracket 133, a feeding rotation drive 131 fixed to the feeding bracket 133, a feeding roller 132 rotatably mounted on the feeding bracket 133 about an axis in a second direction, the feeding bracket 133 fixedly mounted on the correction connecting plate 124, and the feeding bracket 133 is spaced apart from the rotating module 123 and the bearing plate 110 in the first direction, providing clearance space for the rotation of the rotating module 123 and the bearing plate 110 to avoid interference.

[0040] For example, please refer to Figure 5 and Figure 6 A feeding clearance groove 114 is provided on the side of the support plate 110 near the feeding mechanism 130. The feeding clearance groove 114 is arranged through the second direction and has a concave arc-shaped cross-section adapted to the shape and size of the feeding roller 132. Part of the feeding roller 132 is located in the feeding clearance groove 114. The arrangement of the feeding clearance groove 114 allows the feeding roller 132 to be as close as possible to the support plate 110 in the first direction, reducing the gap between the upper surface of the support plate 110 and the top of the feeding roller 132, improving the structural compactness, and reducing the horizontal span of the workpiece 1000 to be rolled.

[0041] For the structure of the feeding bracket 133, please refer to... Figure 5 The feeding bracket 133 includes a feeding base plate 1331, a drive mounting plate 1332, and two roller mounting plates 1333. The feeding base plate 1331 is configured with a T-shaped structure and includes a longitudinal plate 13311 and a transverse plate 13312. The longitudinal plate 13311 extends along a second direction and is fixed to the correction connecting plate 124. The transverse plate 13312 is connected to one end of the longitudinal plate 13311 and is spaced apart from the bearing plate 110 in the second direction. A movable mounting plate 1332 is fixed above the transverse plate 13312. A feeding rotary drive component 131 is mounted on the drive mounting plate 1332, and the feeding rotary drive component 131 passes through a through hole in the drive mounting plate 1332. Two roller mounting plates 1333 are spaced apart along the second direction and fixed to the longitudinal plate 13311. The two ends of the feeding roller 132 are rotatably mounted on the roller mounting plates 1333 via bearings. The top height of the feeding roller 132 is flush with the upper surface of the bearing plate 110. The longitudinal plate 13311 expands the distance between the two roller mounting plates 1333, enabling it to accommodate the installation requirements of feeding rollers 132 of different lengths. The transverse plate 13312 expands the width of the drive mounting plate 1332, improving the stability of the feeding rotary drive component 131.

[0042] To monitor in real time whether the correction is complete, please refer to... Figure 3 and Figure 5 The correction feeding device 100 also includes a correction sensor 140. The correction sensor 140 is a photoelectric sensor. The correction sensor 140 is installed on the side of the feeding bracket 133 near the support plate 110. The correction sensor 140 can detect the position and orientation of the workpiece 1000 to be rolled on the support plate 110. By comparing the measured values ​​with the preset standard values, it can determine whether the correction is completed.

[0043] For the mounting structure of the correction sensor 140, please refer to... Figure 5 The feeding bracket 133 is connected to a horizontally positioned detection plate 141 via fastening screws on the side near the support plate 110. A correction sensor 140 is mounted on the detection plate 141. (Please refer to the corresponding diagram.) Figure 5 and Figure 6 The support plate 110 has an avoidance notch 113 on the side near the feeding bracket 133. At least part of the correction sensor 140 and the detection plate 141 are located in the avoidance notch 113. The upper end of the correction sensor 140 is lower than the upper surface height of the support plate 110, thereby avoiding interference between the correction sensor 140 and the workpiece 1000 to be rolled.

[0044] Please refer to Figures 3 to 5In order to help limit the position of the workpiece 1000 to be rolled on the support plate 110, a limiting plate 150 is also installed on the upper surface of the support plate 110. The limiting plate 150 extends along the first direction and is installed on the side above the support plate 110 in the second direction. The side wall of the limiting plate 150 helps to limit the position of the workpiece 1000 to be rolled in the second direction. The limiting plate 150 can be installed on the support plate 110 by means of screw fixing or other methods.

[0045] For details regarding the composition of the tube winding device 200, please refer to [link / reference]. Figure 1 , Figure 2 , Figures 8 to 11 The tube winding device 200 includes a tube winding support plate 1, a tube winding mechanism 20, and a welding mechanism 30. The tube winding support plate 1 is vertically mounted on the bottom mounting plate 160. The tube winding support plate 1 and the correction platform 120 are spaced apart along a first direction. Driven by the first translation module 121, the support plate 110 and the feeding mechanism 130 can simultaneously move away from or towards the tube winding support plate 1. The upper end of the tube winding support plate 1 is provided with a tube winding cavity 10, and the tube winding station is located in the tube winding cavity 10. The feeding mechanism 130 can drive the tubes to be wound on the support plate 110. The workpiece 1000 is fed into the tube-shaped cavity 10 along the first direction and wound along the peripheral wall of the tube-shaped cavity 10; the tube-winding mechanism 20 is used to clamp the mandrel 2000 and extend the mandrel 2000 into the tube-shaped cavity 10. The tube-winding mechanism 20 can also drive the mandrel 2000 to rotate in the tube-shaped cavity 10 around the second direction so that the workpiece 1000 to be wound is tightly wound around the outer peripheral surface of the mandrel 2000; the welding mechanism 30 has a movable welding component, which can selectively extend into the tube-shaped cavity 10 and weld the workpiece 1000 to be wound in the winding state.

[0046] In this embodiment, the workpiece 1000 to be wound is specifically fiberglass cloth. Under the coordinated action of the feeding mechanism 130 and the winding mechanism 20, after the workpiece 1000 to be wound is wound three times around the outer peripheral wall of the mandrel 2000, the welding assembly extends into the winding tube cavity 10 and welds the workpiece 1000 to be wound in the winding state, so that the workpiece 1000 to be wound forms an inner tube layer on the outer periphery of the mandrel 2000. Then, the first translation module 121 drives the bearing plate 110 and the feeding mechanism 130 to move backward along the first direction as a whole to tighten the workpiece 1000 to achieve tight winding and improve winding accuracy.

[0047] For example, during the winding process of the workpiece 1000, the mandrel 2000 and the feeding roller 132 rotate in the same direction, and the linear speed of the mandrel 2000 is equal to the linear speed of the feeding roller 132, so as to maintain the shape stability of the workpiece 1000 and avoid abnormalities such as curling.

[0048] For example, please refer to Figures 9 to 11The tube cavity 10 is configured as a circular hole structure extending along the second direction. The arc-shaped inner wall of the tube cavity 10 plays a crucial guiding role in the winding of the workpiece 1000 within it. A film inlet channel 11 is provided above the tube cavity 10 and communicates with it. The film inlet channel 11 extends along the first direction and communicates with the top of the tube cavity 10. The position of the film inlet channel 11 in the height direction is between the top wall of the tube cavity 10 and the top of the mandrel 2000. The end of the film inlet channel 11 facing away from the tube cavity 10 faces the feeding mechanism 130 and is provided with a guide flare 14 so that the workpiece 1000 conveyed by the feeding mechanism 130 can enter. The tube-shaped cavity 10 has a feeding port 12 at one end in the axial direction. The tube-winding mechanism 20 can drive the mandrel 2000 to extend into the tube-shaped cavity 10 through the feeding port 12 in a second direction. The outer diameter of the mandrel 2000 is smaller than the inner diameter of the tube-shaped cavity 10, leaving sufficient space for the workpiece 1000 to be wound around the mandrel 2000. The side wall of the tube-winding support plate 1 is provided with several welding avoidance ports 15 that communicate with the tube-winding cavity 10 to avoid welding components. The welding avoidance ports 15 are located on the side of the tube-winding support plate 1 away from the film inlet channel 11.

[0049] For example, please refer to Figure 8 A positioning detection element 2 is installed at the end of the coiled tube cavity 10 opposite to the feed port 12. The positioning detection element 2 is used to detect the depth to which the mandrel 2000 is inserted into the coiled tube cavity 10 in the second direction. Optionally, the positioning detection element 2 can be a high-precision contact sensor or a non-contact sensor such as a photoelectric sensor or a capacitive proximity switch.

[0050] For example, please refer to Figure 10 and Figure 11 The top of the tube cavity 10 is set as an open structure. The top of the tube support plate 1 is provided with a plurality of upper limit plates 13 spaced apart along the second direction. The bottom of the upper limit plate 13 is provided with a concave arc-shaped inner wall that matches the tube cavity 10 to assist in the winding and guiding of the workpiece 1000. One end of the upper limit plate 13 is connected to the body of the tube support plate 1, and the other end of the tube support plate 1 is spaced apart from the body of the tube support plate 1 in the height direction. The gap between the two forms the film inlet channel 11, and the guide flare 14 is formed at the bottom end of the upper limit plate 13 near the feeding mechanism 130.

[0051] For example, please refer to Figure 10 and Figure 11A feeding clearance groove 16 is provided on the side of the winding tube support plate 1 near the correction platform 120. The feeding clearance groove 16 extends through the winding tube support plate 1 along the second direction. The cross-section of the feeding clearance groove 16 is a concave arc-shaped structure adapted to the shape and size of the feeding roller 132. During the winding process, part of the feeding roller 132 is located in the feeding clearance groove 16. The setting of the feeding clearance groove 16 allows the feeding roller 132 to be as close as possible to the winding tube support plate 1 in the first direction during the winding operation, reducing the interval between the film feeding channel 11 and the top of the feeding roller 132, improving the structural compactness, reducing the horizontal span of the workpiece 1000 to be wound, and reducing the sag of the workpiece 1000 to be wound.

[0052] For details on the construction of the tube winding mechanism 20, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 8 The tube winding mechanism 20 includes a feeding slide module 21, a rotating gripper 22, and a mandrel clamp 23. The rotating gripper 22 is mounted on the power output end of the feeding slide module 21, which is drivable. The rotating gripper 22 reciprocates along a second direction. The mandrel clamp 23 is mounted on the power output end of the rotating gripper 22, which drives the mandrel clamp 23 to clamp the mandrel 2000 and rotate it around the second direction. The rotating gripper 22 can be either an electric or pneumatic rotating gripper. In this embodiment, an electric rotating gripper is used, which allows for precise control of the clamping force and rotation angle of the mandrel 2000.

[0053] For example, the feeding slide module 21 can be a high-precision linear slide, driven by a servo motor, transmitted by a ball screw, and guided by linear guides or crossed roller guides to ensure the control accuracy of translation direction and distance. The rotating gripper 22 has two gripping ends that can move closer or further apart from each other. The gripping ends are equipped with mandrel clamps 23. The rotating gripper 22 can either drive the two mandrel clamps 23 to move towards each other to clamp the mandrel 2000, or drive the mandrel 2000 to rotate around an axis in a second direction to adjust the angle and perform winding operations. It should be noted that both the feeding slide module 21 and the rotating gripper 22 are mature and standard modular components in the prior art, integrating both gripping and rotation functions. Their specific structure and working principle will not be described in detail here.

[0054] For example, the welding mechanism 30 achieves welding of the coil 1000 by contact heating, please refer to... Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 11A welding fixture 34 is fixed on the bottom mounting plate 160. The welding mechanism 30 also includes a welding drive component 31, which is mounted on the welding fixture 34. The welding assembly is mounted on the power output end of the welding drive component 31. The welding drive component 31 can drive the welding assembly to move in a linear direction. The welding assembly includes a heating head 32 and an electric heating rod 33. The heating head 32 is provided with a heating cavity and multiple heating contact parts 321. The electric heating rod 33 is installed in the heating cavity and is used to heat the heating head 32. The multiple heating contact parts 321 are spaced apart along a second direction. The welding drive component 31 can drive the welding assembly to reciprocate in a linear direction so that the multiple heating contact parts 321 selectively extend into the tube cavity 10 and abut against the receiving workpiece 1000 to achieve multi-point heating and welding of the receiving workpiece 1000.

[0055] For example, the heating contact portion 321 is made of ceramic to prevent the heating contact portion 321 from sticking to the workpiece 1000 to be rolled.

[0056] For example, the welding drive 31 can be a linear drive such as a linear cylinder or an electric push rod.

[0057] For example, please refer to Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 12 The tube winding module also includes a first pressing assembly 40, which includes a first pressing drive 41 and a first pressing roller 42. The first pressing drive 41 is mounted on the welding fixing frame 34, and the first pressing roller 42 is mounted on the power output end of the first pressing drive 41 through the first pressing frame 43. The first pressing roller 42 extends along the second direction and is located above the feeding roller 132. The first pressing drive 41 can drive the first pressing roller 42 to reciprocate in the vertical direction to selectively press the workpiece 1000 to be wound onto the feeding roller 132 from above. When the feeding mechanism 130 conveys the workpiece 1000 to the tube cavity 10, the first pressing drive 41 drives the first pressing roller to press the workpiece 1000 against the feeding roller 132 to provide sufficient friction to prevent relative sliding between the workpiece 1000 and the feeding roller 132, and to avoid wrinkling, drifting or deviating of the workpiece 1000 during the conveying process.

[0058] For example, please refer to Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 12The tube winding module also includes a second pressing assembly 50, which includes a second pressing drive 51 and a second pressing roller 52. The second pressing drive 51 is mounted on the welding fixing frame 34, and the second pressing roller 52 is mounted on the power output end of the second pressing drive 51 through the second pressing frame 53. The second pressing roller 52 extends along the second direction and is located directly above the tube winding cavity 10. The second pressing drive 51 can drive the second pressing roller 52 to reciprocate in the vertical direction to selectively press the workpiece 1000 to be wound into the mandrel 2000 in the tube winding cavity 10. After the feeding mechanism 130 feeds the front end of the workpiece 1000 into the tube winding cavity 10 and the workpiece 1000 is wound around the outer circumference of the mandrel 2000, the second pressing drive 51 drives the second pressing roller to press the workpiece 1000 onto the mandrel 2000 to maintain constant tube winding tension and prevent the workpiece 1000 from loosening or deviating during the tube winding process.

[0059] To avoid interference between the second pressing roller 52 and the upper limit plate 13, please refer to... Figure 11 and Figure 12 The gap between adjacent upper limit plates 13 forms a downward pressure relief position. The second downward pressure roller 52 is configured with a segmented structure, including at least two large-diameter portions 521 spaced apart along the second direction. The outer diameter of the large-diameter portion 521 is larger than the outer diameter of the main shaft structure of the second downward pressure roller 52. The large-diameter portions 521 are arranged one-to-one with the downward pressure relief positions. The top of the upper limit plate 13 is provided with a downward pressure relief groove 17 to avoid the main shaft structure of the second downward pressure roller 52. The upper end of the tube support plate 1 is provided with a downward pressure relief notch 18 at the position corresponding to the downward pressure relief position. The upper surface of the downward pressure relief position is configured as an inwardly concave arc surface structure that matches the shape and size of the large-diameter portion 521.
