Description

Technical Field

[0001] The present invention relates to the technical field of composite pipe manufacturing, and more particularly to an automatic weaving device for a wire mesh pipe skeleton. Background Art

[0002] While traditional PE pipes offer advantages such as corrosion resistance, light weight, and good flexibility, their insufficient pressure-bearing capacity and rigidity limit their use in high-pressure environments. To improve performance, PE steel mesh pipes were developed. These pipes incorporate a mesh framework of high-strength steel wire embedded between the inner and outer layers of high-density polyethylene (HDPE), creating a rigid-flexible composite structure that combines the corrosion resistance of plastic pipes with the compressive strength of metal pipes. Currently, the steel mesh framework is primarily produced using a dual-machine forward and reverse winding process: two independent wire winding machines wind the inner PE pipe surface in forward and reverse directions, respectively, creating a cross-shaped steel wire layer.

[0003] In the prior art, Chinese invention patent application CN119870330A discloses a wire winding device for a wire mesh skeleton composite pipe, comprising a support base, on which are arranged in sequence a turntable mechanism, a guide frame assembly, a wire surface grinding mechanism, a debris cleaning and adsorption mechanism, a wire winding mechanism, a gluing mechanism, and a pressing mechanism. The turntable mechanism comprises an annular rotating wheel, a transmission ring is fixedly provided on one side of the annular rotating wheel, a rotating seat is provided on the outside of the transmission ring and is rotatably connected, the bottom of the rotating seat is connected to the support base via a bracket and screws, a connecting circular plate is provided on the inside of the annular rotating wheel and is connected via screws, and a connecting tube is provided through the middle of the connecting circular plate and is connected via screws. However, in the wire mesh skeleton produced by this wire winding device, the adjacent wires in each layer of wire lack axial constraints, and wire slippage is likely to occur when subjected to axial force, resulting in uneven spacing between adjacent wires, which leads to a decrease in the performance of the PE wire mesh pipe. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that adjacent steel wires lack axial restrictions, steel wire slippage is likely to occur when subjected to axial force, and the performance of PE steel wire mesh pipes is reduced. An automatic weaving device for a steel wire mesh pipe skeleton is provided, which can make adjacent forward and reverse rotating steel wires overlap with each other, the steel wires are not easily displaced, the mesh structure is uniform and stable, and the overall structural strength is improved.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: Provided is an automatic weaving device for a wire mesh pipe skeleton, comprising a first winding assembly, a second winding assembly, a transmission assembly, a drive assembly and a frame, wherein the frame is provided with a through hole, the first winding assembly and the second winding assembly are both rotatably connected to the frame, and the through hole, the first winding assembly and the second winding assembly are coaxially arranged; the transmission assembly and the drive assembly are both fixed on the frame, the transmission assembly is connected between the first winding assembly, the second winding assembly and the drive assembly, and the first winding assembly and the second winding assembly rotate in opposite directions.

[0006] The automatic weaving device for the steel wire mesh pipe skeleton of the present invention is powered by a driving assembly, and the transmission assembly transmits the power to the first winding assembly and the second winding assembly, so that the coaxially arranged first winding assembly and the second winding assembly maintain opposite rotation directions, thereby simultaneously performing forward winding and reverse winding on the surface of the pipe passing through the through hole. Only one device is needed to independently weave overlapping steel wire mesh pipe skeletons, reducing space occupied volume and production costs. At the same time, adjacent forward and reverse rotating steel wires restrain each other at the overlapping points, effectively preventing the steel wire from slipping along the axial direction of the pipe when axial force is applied, and significantly improving the uniformity and structural stability of the steel mesh skeleton grid.

[0007] Furthermore, the transmission assembly includes a transmission shaft, a transmission belt, a pulley, a first drive gear, a second drive gear, and a first transmission gear. The transmission shaft rotatably passes through the frame, and a pulley and the first drive gear are fixed at one end thereof, and a second drive gear is fixed at the other end thereof. The transmission belt connects the pulley and the drive assembly, the first drive gear meshes with the first transmission gear, the first transmission gear meshes with the first winding assembly, and the second drive gear meshes with the second winding assembly. The drive assembly drives the pulley to rotate through the transmission belt, thereby causing the transmission shaft fixed to the pulley to rotate in the frame, driving the first drive gear and the second drive gear respectively arranged at both ends of the transmission shaft to rotate, the first drive gear meshes with the first transmission gear, and then drives the first winding assembly to rotate through the first transmission gear, while the second drive gear directly meshes with the second winding assembly, thereby maintaining opposite rotation directions between the first winding assembly and the second winding assembly, completing forward winding and reverse winding on the surface of the pipe, causing the steel wires to overlap with each other.

[0008] Furthermore, the first winding assembly includes a first rotating disk, a second rotating disk, a third rotating disk, a first winding disk group, and a first roller assembly. The second rotating disk and the third rotating disk are fixed to the first rotating disk. The first rotating disk is provided with a first gear ring that meshes with the first driving gear. The first winding disk group is fixed to the second rotating disk, and the first roller assembly is arranged on the third rotating disk. The steel wire is wound on the first winding disk group and passes through the first roller assembly to reach the surface of the pipe. The first rotating disk meshes with the first driving gear through the first gear ring. At the same time, the second and third rotating disks are fixed to the first rotating disk, and the first winding disk group is arranged on the second rotating disk, and the first roller assembly is arranged on the third rotating disk, forming a coaxially linked layered structure. The guiding function of the first roller assembly is used to ensure the accurate winding position of the steel wire, so that the forward-wound steel wire can be stably rotated and transported under the drive of the first gear ring.

[0009] Furthermore, the second winding assembly includes a second gear ring, a gear group, a second winding disk group, a second roller assembly, an arcuate slide rail and an arcuate slider slidably connected to the arcuate slide rail. The outer circumference of the second gear ring is provided with a first gear segment engaged with the second driving gear, and the inner circumference is provided with a second gear segment engaged with the gear group. The second gear ring is rotatably connected to the second rotating disk; the arcuate slider is provided with a third gear segment engaged with the gear group, and a circumferential annular groove is provided between the second rotating disk and the third rotating disk. The arcuate slide rail is arranged in the annular groove and fixed to the first rotating disk; the second winding disk group is fixed on the second gear ring, and the second roller assembly is fixed on the arcuate slider. The second drive gear meshes with the first gear segment, driving the second gear ring to rotate and drive the second winding disc assembly, which cooperates with the guidance of the second roller assembly to complete the reverse wire winding. At the same time, the gear group meshes with the second gear segment inside the second gear ring and the third gear segment on the arc-shaped slider, allowing the arc-shaped slider to slide periodically along the arc-shaped slide rail fixed to the first rotating disc, driving the second roller assembly to produce circumferential displacement. Through the coordinated action of multiple sets of gear transmission and slide rail mechanisms, the reverse-wound wire is synchronously periodically offset circumferentially during rotation, forming a mechanically interlocked overlapping structure with the forward-wound wire, effectively preventing axial slippage of the wire and improving the uniformity and overall structural strength of the skeleton grid.

[0010] Furthermore, the side of the second gear ring is provided with a first annular groove, in which a bearing rotatably connected to the second rotating disk is provided. The inner circumference of the second gear ring is also provided with a first empty tooth segment, which is alternately connected to the second gear segment. The second gear ring is supported by a bearing inside to enable smooth rotation of the second gear ring relative to the second rotating disk. The first gear segment on the outer circumference is continuously engaged with the second drive gear to achieve stable power input. The alternating meshing design of the second gear segment and the first empty tooth segment on the inner circumference enables intermittent transmission of the gear set, accurately controlling the circumferential displacement rhythm of the second roller assembly, and achieving regular overlapping weaving of the reverse steel wire and the forward steel wire.

[0011] Furthermore, the gear set includes a second transmission gear and a third transmission gear. The second transmission gear is meshed with the second gear segment and the third transmission gear, and the third transmission gear is meshed with the third gear segment. When the second transmission gear disengages from the second gear segment, the arc-shaped slider moves to the end position of the arc-shaped slide rail. The second gear segment is meshed with the second transmission gear, and the second transmission gear is meshed with the third transmission gear. Finally, the meshing transmission of the third transmission gear and the third gear segment drives the arc-shaped slider to move, so that the second gear ring and the arc-shaped slider maintain the same rotation direction. When the second transmission gear disengages and enters the first empty tooth segment, the arc-shaped slider stops moving and stops at the end of the slide rail, realizing intermittent displacement control of the arc-shaped slider, ensuring that the second roller assembly can pause at a specific position, so that the reverse steel wire can be accurately embedded in the forward steel wire layer to form a mechanical interlocking node.

[0012] Furthermore, it also includes an adjustment component, wherein the first rotating disk is provided with a radial sliding groove, and the second rotating disk and the third rotating disk are both provided with a radial avoidance groove, the projection of the avoidance groove on the first rotating disk coincides with the sliding groove, a first slider is provided in the sliding groove, the first roller assembly is connected to the first slider, and the adjustment component is used to drive the first slider to reciprocate in the sliding groove and the avoidance groove. The adjustment component drives the first slider to reciprocate in the radial sliding groove and the avoidance groove that passes through the upper and lower parts, driving the first roller assembly to achieve radial position adjustment, realizing dynamic adjustment of the radial spacing of the forward-winding steel wire, and forming an optimized three-dimensional mesh structure through overlapping weaving with the reverse steel wire, thereby improving the dimensional stability of the pipe and avoiding axial slippage.

[0013] Furthermore, the adjustment assembly includes a third gear ring, a slider-crank mechanism, and a second slider connected to the first slider. The second slider is connected to the slider-crank mechanism, and the third gear ring engages with the second drive gear and drives the slider-crank mechanism. The third gear ring is driven to rotate by the second drive gear, and the slider-crank mechanism converts its rotational motion into linear motion, driving the second slider and the connected first slider to reciprocate within the sliding groove. This achieves automatic radial adjustment of the first roller assembly, ensuring periodic and stable overlap of the forward wire winding and the reverse wire winding, making the weaving process of the wire mesh skeleton more stable and reliable, and improving the structural consistency and mechanical properties of the product.

[0014] Furthermore, the crank slider mechanism includes a fourth transmission gear, a first connecting rod, a second connecting rod, and a rotating shaft. The outer circumference of the third gear ring is provided with a fourth gear segment that meshes with the second drive gear, and the inner circumference is provided with a fifth gear segment and a second idle tooth segment that are alternately connected. The fourth transmission gear is fixed to the rotating shaft and meshes with the fifth gear segment. One end of the first connecting rod is rotationally connected to the rotating shaft, and the other end is connected to the second connecting rod, and the second connecting rod is connected to the second slider. When the third gear ring rotates, the fifth gear segment on its inner circumference intermittently meshes with the fourth transmission gear, driving the rotating shaft and the first connecting rod to swing. This is converted into linear reciprocating motion of the second slider via the second connecting rod, achieving accurate control of the periodic radial displacement of the first roller assembly, giving the woven wire mesh skeleton a uniform and stable three-dimensional interlocking structure, significantly improving the axial anti-slip ability and circumferential pressure bearing performance of the pipe.

[0015] Furthermore, the number of teeth on the fourth transmission gear is twice that of the fifth gear segment. By controlling the number of teeth on the fourth transmission gear to be twice that of the fourth gear segment, the fourth transmission gear rotates exactly half a turn from the start to the end of engagement with the fourth gear segment, thereby driving the first roller assembly to move exactly from one end of the sliding end to the other end, ensuring the stability of the wire winding effect.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the counter-rotating first and second winding assemblies, the device can simultaneously perform forward and reverse wire winding. Adjacent forward and reverse rotating wires restrain each other at the overlapping point, effectively preventing the wires from slipping along the axial direction of the pipe when subjected to axial force, significantly improving the uniformity and structural stability of the wire mesh skeleton grid; 2. The overall structure of the device is compact. Only one winding device and mechanical transmission are needed to complete the weaving of the wire mesh, which reduces the floor space and production costs. 3. The design of the empty tooth segments on the second gear ring and the third gear ring realizes intermittent meshing control, ensuring the precise control of the circumferential motion of the second roller assembly and the radial adjustment motion of the first roller assembly, thus achieving stable and uniform weaving.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0021] Example 1 This embodiment is the first embodiment of the automatic weaving device for the wire mesh pipe skeleton, which includes a first winding assembly 100, a second winding assembly 200, a transmission assembly 300, a drive assembly 400 and a frame 500. The frame 500 is provided with a through hole, and the first winding assembly 100 and the second winding assembly 200 are both rotatably connected to the frame 500. The through hole, the first winding assembly 100 and the second winding assembly 200 are coaxially arranged; the transmission assembly 300 and the drive assembly 400 are both fixed on the frame 500, and the transmission assembly 300 is connected between the first winding assembly 100, the second winding assembly 200 and the drive assembly 400. The first winding assembly 100 and the second winding assembly 200 rotate in opposite directions.

[0022] like Figure 1 As shown, the automatic weaving device for the wire mesh pipe skeleton in this embodiment is powered by the driving component 400, and the transmission component 300 transmits the power to the first winding component 100 and the second winding component 200, so that the coaxially arranged first winding component 100 and the second winding component 200 maintain opposite rotation directions, thereby simultaneously performing forward winding and reverse winding on the surface of the pipe passing through the through hole. Only one device is needed to independently weave overlapping wire mesh pipe skeletons, reducing the space occupied volume and production costs. At the same time, adjacent forward and reverse rotating steel wires restrain each other at the overlapping points, effectively preventing the steel wire from slipping along the axial direction of the pipe when subjected to axial force, and significantly improving the uniformity and structural stability of the wire mesh skeleton grid.

[0023] The transmission assembly 300 in this embodiment includes a transmission shaft 310, a transmission belt 320, a pulley 330, a first driving gear 340, a second driving gear 350, and a first transmission gear 360. The transmission shaft 310 rotatably passes through the frame 500. One end of the transmission shaft 310 is fixed with a pulley 330 and a first driving gear 340, and the other end is fixed with a second driving gear 350. The transmission belt 320 connects the pulley 330 and the driving assembly 400. The first driving gear 340 is meshed with the first transmission gear 360. The first transmission gear 360 is meshed with the first winding assembly 100, and the second driving gear 350 is meshed with the second winding assembly 200. Figure 2 As shown, the drive assembly 400 drives the pulley 330 via the transmission belt 320, thereby rotating the transmission shaft 310 fixedly connected to the pulley 330 within the frame 500, driving the first drive gear 340 and the second drive gear 350, respectively disposed at opposite ends of the transmission shaft 310, to rotate. The first drive gear 340 meshes with the first transmission gear 360, which in turn drives the first winding assembly 100 to rotate via the first transmission gear 360. The second drive gear 350 directly meshes with the second winding assembly 200, thereby maintaining opposite rotational directions between the first winding assembly 100 and the second winding assembly 200. This completes forward and reverse winding on the surface of the pipe, causing the wires to overlap. In this embodiment, the rotational speed of the second winding assembly 200 is twice that of the first winding assembly 100.

[0024] like Figure 3 、 Figure 4 As shown, the first winding assembly 100 in this embodiment includes a first rotating disk 110, a second rotating disk 120, a third rotating disk 130, a first winding disk group 140 and a first roller assembly 150. The second rotating disk 120 and the third rotating disk 130 are fixed on the first rotating disk 110. The first rotating disk 110 is provided with a first gear ring 111 that engages with the first driving gear 340. The first winding disk group 140 is fixed on the second rotating disk 120, and the first roller assembly 150 is arranged on the third rotating disk 130. The steel wire is wound on the first winding disc group 140 and passes through the first roller assembly 150 to reach the surface of the pipe. The first rotating disc 110 is engaged with the first driving gear 340 through the first gear ring 111. At the same time, the second and third rotating discs 130 are fixed to the first rotating disc 110, and the first winding disc group 140 is set on the second rotating disc 120, and the first roller assembly 150 is set on the third rotating disc 130, forming a coaxially linked layered structure. The guiding function of the first roller assembly 150 is used to ensure the accurate winding position of the steel wire, so that the forwardly wound steel wire can be stably rotated and transported under the drive of the first gear ring 111.

[0025] The second winding assembly 200 in this embodiment includes a second gear ring 210, a gear set 220, a second winding disc set 230, a second roller assembly 240, an arcuate slide rail 250, and an arcuate slider 260 slidably connected to the arcuate slide rail 250. The outer circumference of the second gear ring 210 is provided with a first gear segment 211 meshing with the second driving gear 350, and the inner circumference is provided with a second gear segment 212 meshing with the gear set 220. The second gear ring 210 is rotatably connected to the second rotating disk 120; the arcuate slider 260 is provided with a third gear segment 261 meshing with the gear set 220, and a circumferential annular groove 121 is provided between the second rotating disk 120 and the third rotating disk 130. The arcuate slide rail 250 is arranged in the annular groove 121 and is fixed to the first rotating disk 110; the second winding disc set 230 is fixed on the second gear ring 210, and the second roller assembly 240 is fixed on the arcuate slider 260. Figure 5 、 Figure 7 As shown, the second drive gear 350 meshes with the first gear segment 211, thereby driving the second gear ring 210 to rotate and drive the second winding disc assembly 230, cooperating with the guiding function of the second roller assembly 240 to complete the reverse wire winding. At the same time, the gear group 220 meshes with the second gear segment 212 inside the second gear ring 210 and the third gear segment 261 on the arc-shaped slider 260, allowing the arc-shaped slider 260 to slide periodically along the arc-shaped slide rail 250 fixed to the first rotating disk 110, driving the second roller assembly 240 to produce circumferential displacement. Through the coordinated action of multiple sets of gear transmission and the slide rail mechanism, the reversely wound steel wire is synchronously periodically offset circumferentially during rotation, thereby forming a mechanically interlocked overlapping structure with the forwardly wound steel wire, effectively preventing axial slippage of the steel wire and improving the uniformity and overall structural strength of the skeleton grid.

[0026] like Figure 5 、 Figure 7 As shown, in this embodiment, 8 arc-shaped sliders 260 and arc-shaped slide rails 250 are evenly arranged along the center of the circular groove 121, and a threaded mounting hole is set in the center of the main body of the arc-shaped slider 260. The second roller assembly 240 is fixedly mounted on the arc-shaped slider 260 through the threaded mounting hole.

[0027] The working principle of this embodiment is as follows: the drive assembly 400 drives the drive shaft 310 to rotate through the transmission belt 320, so that the first drive gear 340 and the second drive gear 350 rotate synchronously; the first drive gear 340 drives the first winding assembly 100 to rotate forward through the first transmission gear 360, and the steel wire is output through the first winding disc group 140 and guided by the first roller assembly 150, forming a forward spiral winding on the surface of the pipe; at the same time, the second drive gear 350 drives the second gear ring 210 to rotate in the opposite direction, driving the second winding disc group 230 to output the reverse steel wire, and through the meshing transmission of the gear group 220 and the arc-shaped slider 260, the second roller assembly 240 slides periodically along the arc-shaped slide rail 250, generating regular circumferential displacement, so that the reverse steel wire and the forward steel wire form a precisely staggered mechanical interlocking structure.

[0028] Example 2 This embodiment is the second embodiment of the automatic weaving device for the wire mesh tube skeleton. This embodiment is similar to the first embodiment, except that Figure 8 As shown, the second gear ring 210 has a first annular groove 213 on its side. A bearing rotatably connected to the second rotating disk 120 is located in the first annular groove 213. The inner circumference of the second gear ring 210 also has a first hollow tooth segment 214, which is alternately connected to the second gear segment 212. The second gear ring 210 is supported by a bearing to ensure smooth rotation relative to the second rotating disk 120. The first gear segment 211 on the outer circumference is continuously engaged with the second drive gear 350 to achieve stable power input. The alternating engagement of the second gear segment 212 and the first hollow tooth segment 214 on the inner circumference creates intermittent transmission for the gear set 220, precisely controlling the circumferential displacement rhythm of the second roller assembly 240 and achieving regular overlapping weaving of the reverse and forward steel wires.

[0029] In this embodiment, the second gear segments 212 are divided into eight segments, each with a central angle of 30°. On the inner circumference of the second gear ring 210, the second gear segments 212 are alternately connected to the first idle tooth segments 214. In this embodiment, the overall transmission ratio between the second gear ring 210 and the arcuate slider 260 is 2 / 3. This means that after the second gear segment 212 rotates 30°, the arcuate slider 260 rotates 45°, and the first tooth of the second gear segment 212 is aligned with the centerline of the arcuate slider 260.

[0030] like Figure 5As shown, the gear set 220 in this embodiment includes a second transmission gear 221 and a third transmission gear 222. The second transmission gear 221 meshes with the second gear segment 212 and the third transmission gear 222, and the third transmission gear 222 meshes with the third gear segment 261. When the second transmission gear 221 disengages from the second gear segment 212, the arcuate slider 260 moves to the end position of the arcuate slide rail 250. The second gear segment 212 meshes with the second transmission gear 221, which in turn meshes with the third transmission gear 222. Ultimately, the meshing transmission between the third transmission gear 222 and the third gear segment 261 drives the arcuate slider 260 to move, thereby ensuring that the second gear ring 210 and the arcuate slider 260 maintain the same rotational direction. When the second transmission gear 221 disengages and enters the first empty tooth segment 214, the arcuate slider 260 stops moving and rests at the end of the slide rail, achieving intermittent displacement control of the arcuate slider 260. This ensures that the second roller assembly 240 can pause at a specific position, allowing the reverse wire to accurately embed into the forward wire layer to form a mechanical interlocking node. In this embodiment, the gear set 220 is mounted on the second rotating disk 120, and eight gear sets are evenly distributed around the center of the second rotating disk 120, each meshing with eight arcuate sliders 260.

[0031] The working principle of this embodiment is as follows: the driving assembly 400 drives the first winding assembly 100 to rotate forward through the transmission system, and at the same time, the second driving gear 350 drives the second gear ring 210 to rotate in the opposite direction; the second gear ring 210 is supported by the bearing to achieve smooth rotation, and the second gear segments 212 and the first empty tooth segments 214 alternately arranged on its inner circumference cause the gear set 220 to produce intermittent meshing transmission; when the second gear segment 212 is meshed with the second transmission gear 221, the power is transmitted to the third gear segment 261 of the arc-shaped slider 260 through the third transmission gear 222, driving the arc-shaped slider 260 to move synchronously along the slide rail; when the second transmission gear 221 enters the first empty tooth segment 214, the arc-shaped slider 260 stops precisely at the end position of the slide rail, and at this time, the first tooth of the second gear segment 212 is aligned with the center line of the arc-shaped slider 260.

[0032] Example 3 This embodiment is the third embodiment of the automatic weaving device for the wire mesh tube skeleton. This embodiment is similar to the first embodiment, except that it further includes an adjustment assembly 600. The first rotating disk 110 is provided with a radial sliding groove 112, and the second rotating disk 120 and the third rotating disk 130 are both provided with a radial avoidance groove 122. The projection of the avoidance groove 122 on the first rotating disk 110 coincides with the sliding groove 112. A first slider 113 is provided in the sliding groove 112. The first roller assembly 150 is connected to the first slider 113. The adjustment assembly 600 is used to drive the first slider 113 to reciprocate in the sliding groove 112 and the avoidance groove 122. The adjustment assembly 600 drives the first slider 113 to reciprocate in the radial sliding groove 112 and the avoidance groove 122 that runs through the top and bottom, driving the first roller assembly 150 to achieve radial position adjustment, thereby achieving dynamic adjustment of the radial spacing of the forward-winding steel wires. By overlapping and weaving with the reverse-winding steel wires, an optimized three-dimensional mesh structure is formed, improving the dimensional stability of the pipe and preventing axial slippage.

[0033] like Figure 6 As shown, the adjustment assembly 600 in this embodiment includes a third gear ring 610, a slider crank mechanism 620, and a second slider 630 connected to the first slider 113. The second slider 630 is connected to the slider crank mechanism 620. The third gear ring 610 engages with the second drive gear 350 and drives the slider crank mechanism 620 to move. The third gear ring 610 is driven to rotate by the second drive gear 350, and its own rotational motion is converted into linear motion through the slider crank mechanism 620, driving the second slider 630 and the first slider 113 connected thereto to move back and forth within the sliding groove 112. This achieves automatic radial adjustment of the first roller assembly 150, ensures that the forward steel wire winding and the reverse steel wire periodically overlap stably, makes the weaving process of the wire mesh skeleton more stable and reliable, and improves the structural consistency and mechanical properties of the product.

[0034] like Figure 9 As shown, in this embodiment, a second annular groove 614 is provided on the side of the third gear ring 610. A bearing rotatably connected to the first rotating disk 110 is disposed in the second annular groove 614. A connecting ring 615 is also provided between the third gear ring 610 and the second gear ring 210. The bearing supports the third gear ring 610 to achieve smooth relative rotation with the first rotating disk 110. The connecting ring 615 maintains synchronous linkage with the second gear ring 210, reducing rotational friction loss and ensuring smooth movement of the third gear ring 610 when driving the slider-crank mechanism 620.

[0035] The crank slider mechanism 620 in this embodiment includes a fourth transmission gear 621, a first connecting rod 622, a second connecting rod 623 and a rotating shaft. The outer circumference of the third gear ring 610 is provided with a fourth gear segment 611 meshing with the second drive gear 350, and the inner circumference is provided with a fifth gear segment 612 and a second empty tooth segment 613 alternately connected. The fourth transmission gear 621 is fixed on the rotating shaft and meshes with the fifth gear segment 612. One end of the first connecting rod 622 is rotatably connected to the rotating shaft, and the other end is connected to the second connecting rod 623. The second connecting rod 623 is connected to the second slider 630. As the third gear ring 610 rotates, the fifth gear segment 612 on its inner circumference intermittently engages the fourth transmission gear 621, driving the rotating shaft and first connecting rod 622 to oscillate. This is converted into linear reciprocating motion by the second connecting rod 623 for the second slider 630. This accurately controls the periodic radial displacement of the first roller assembly 150, resulting in a uniform and stable three-dimensional interlocking structure for the woven wire mesh skeleton, significantly improving the pipe's axial anti-slip capability and circumferential pressure-bearing performance. In this embodiment, the fifth gear segment 612 is divided into eight segments, each occupying a 15° central angle. On the inner circumference of the third gear segment 261, the fifth gear segments 612 and the third gear segments 261 are alternately connected.

[0036] In this embodiment, the fourth transmission gear 621 has twice the number of teeth of the fifth gear segment 612. By controlling the number of teeth of the fourth transmission gear 621 to be twice the number of teeth of the fourth gear segment 611, the fourth transmission gear 621 rotates exactly half a turn from the start to the end of engagement with the fourth gear segment 611, thereby driving the first roller assembly 150 to move exactly from one end of the sliding end to the other end, ensuring the stability of the wire winding effect.

[0037] In this embodiment, both the sliding groove 112 and the avoidance groove 122 are linear, and eight avoidance grooves 122 are evenly distributed along the center of the circular groove 121. The avoidance grooves 122 intersect with the circular groove 121. When the arc-shaped slider 260 moves to a position that coincides with the arc-shaped slide rail 250, the avoidance groove 122 on the second rotating disk 120 communicates with the avoidance groove 122 on the third rotating disk 130, allowing the first roller assembly 150 to complete stable radial movement therein. After the first roller assembly 150 moves to the other end of the avoidance groove 122, the second gear segment 212 disengages from the first idle tooth segment 214 and enters into engagement with the second gear segment 212, thereby causing the arc-shaped slider 260 to continue to rotate circumferentially, and this cycle repeats.

[0038] The operating principle of this embodiment is as follows: After the drive system is activated, the second drive gear 350 simultaneously drives the second gear ring 210 and the third gear ring 610 to rotate. The third gear ring 610 rotates smoothly thanks to bearing support, and the fifth gear segment 612 on its inner circumference intermittently engages the fourth transmission gear 621. When the fifth gear segment 612 engages, the fourth transmission gear 621 rotates half a revolution, driving the first roller assembly 150 through a connecting rod mechanism to complete a complete radial reciprocating motion. Subsequently, the second gear ring 210 drives the arcuate slider 260 to complete a circumferential displacement. When the second gear segment 212 is engaged, the arcuate slider 260 begins to move, and the first roller assembly 150 stops at the end of the sliding groove 112 and the avoidance groove 122. When the second gear segment 212 is disengaged and enters the first idle tooth segment 214, the arcuate slider 260 stops moving, and the first roller assembly 150 begins to move to the end of the sliding groove 112 and the avoidance groove 122.
