Description

Technical Field

[0001] This technical solution relates to the field of wire mesh welding equipment technology, specifically a wire mesh welding machine and its control method. Background Technology

[0002] In the process of oil and gas drilling and production, screen pipes are usually used for sand control to prevent sand from being produced in oil and gas wells, which could damage casing and equipment and reduce production.

[0003] For example, Chinese patent CN202110256197.5 discloses a sand-control screen pipe and its application, and Chinese patent CN200620012375.0 discloses a multi-layer stainless steel metal mesh sand-control screen pipe. These screen pipes generally include an inner central pipe (also called an inner sheath or base pipe) and a mesh cloth (including an inner drainage mesh and a variable precision composite sand-blocking layer, or a metal mesh sand-control screen sleeve) wrapped around the outside of the central pipe.

[0004] However, there are still some shortcomings in the existing screen tube production process: the stacking, feeding, and cutting of the mesh fabric need to be done manually, and the cut mesh fabric also needs to be manually wound onto the central tube before being welded onto the central tube by a welding device. This results in high labor costs and low welding quality and efficiency, which affects the production schedule. Summary of the Invention

A control method for a wire mesh welding machine includes the following steps: Step S1: By adjusting the slide to move upward on the guide rod, the first roller and the second roller are moved away from each other to open the conveyor roller group; the multi-layer wire mesh in the storage mechanism is aligned and stacked, and the front end of the wire mesh passes through the first conveyor roller group until it reaches the second conveyor roller group; the position of the limiting block is adjusted on the pad so that the limiting block abuts against both sides of the wire mesh; the slide is adjusted to move downward on the guide rod, the first roller and the second roller are moved closer to each other to close the conveyor roller group.

[0016] Step S2: The conveyor roller mechanism transports the front end of the mesh fabric to the cutting mechanism; the conveyor roller mechanism extends the front end of the mesh fabric out of the cutting mechanism, and the cutting mechanism cuts off the front end of the mesh fabric, so that the front ends of the multiple layers of mesh fabric are aligned.

[0017] Step S3: The traction slide moves toward the cutting mechanism, then the traction gripper clamps the front end of the mesh fabric, and the traction slide moves away from the cutting mechanism to pull out the mesh fabric; during the process of the traction slide pulling out the mesh fabric, the conveying roller mechanism transports the mesh fabric to the cutting mechanism, and the spot welding mechanism performs spot welding on the mesh fabric at set intervals; at the same time, during the process of the traction slide pulling out the mesh fabric, the support mechanism opens and supports the lower end of the mesh fabric;

[0018] Step S4: After the traction slide pulls the net to the set length, the clamping mechanism clamps the rear half of the net, the cutting mechanism cuts the net, and the traction slide moves away from the cutting mechanism, so that the rear end of the net moves to the clamping mechanism; then the first transport component clamps the front end of the net, and the second transport component clamps the rear end of the net; the traction gripper releases the net and moves away from the net.

[0019] Step S5: The loading and unloading mechanism loads the central tube onto the supporting rotating mechanism. The welding beam moves above the central tube. The pusher plate of the pusher assembly descends. The drive assembly drives the pusher plate to abut against one end of the central tube and drives the central tube to move towards the gripper chuck. The gripper chuck holds the other end of the central tube. The pusher plate rises and leaves the central tube. The inner support rod is inserted into the central tube. Step S5 can be executed simultaneously with steps S1-S4.

[0020] Step S6: Transport component one and transport component two move the mesh towards the central tube, so that the side end of the mesh crosses the vertical plane where the center line of the central tube is located; the clamping mechanism clamps the end of the mesh onto the central tube; the third electrode of welding component one moves to the clearance area for welding, and at the same time the inner support rod moves, so that the fourth electrode corresponds to the third electrode to achieve welding; transport component one and transport component two release the two ends of the mesh and move to the initial position;

[0021] Step S7: After one side of the mesh is welded to the central tube, the drive component thirteen drives the chuck to rotate at a set angle, so that the mesh is wound around the central tube and the other side of the mesh is placed between the third electrode and the fourth electrode. Then the third electrode of the welding component one moves to the clearance area for welding.

[0022] Step S8: After the mesh is welded onto the central tube, the welding beam drives welding component one away from the upper end of the central tube, the inner support rod of welding component two away from the central tube, the flip plate of the clamping mechanism is lifted, the chuck releases the central tube, and the lifting component lifts the central tube from the support component; the loading and unloading mechanism unloads the central tube with the welded mesh.

[0023] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0024] 1. This technical solution uses a feeding device to stack, feed, and cut multiple layers of mesh fabric. Then, the cut mesh fabric is transported to the welding device by a feeding device. Finally, the welding device welds the mesh fabric to the central tube, thus realizing the mechanization of the production process and improving production efficiency and quality.

[0025] 2. The feeding device of this technical solution transports the mesh fabric in the storage mechanism to the cutting mechanism for cutting through the conveying roller mechanism, eliminating the need for manual stacking and feeding of the mesh fabric;

[0026] 3. This technical solution uses a limiting mechanism to align the sides of the multi-layer mesh fabric, avoiding misalignment between the multi-layer mesh fabrics that would affect production quality and ensuring a high yield rate.

[0027] 4. This technical solution uses a spot welding mechanism to weld the multi-layered aligned mesh together, preventing the mesh from separating and misaligning during subsequent transportation, ensuring the alignment of the mesh after welding to the central tube, and improving product quality.

[0028] 5. This technical solution is designed with a traction mechanism to take out the cut mesh fabric and transport it to the next work station under the operation of the conveying mechanism, thereby realizing the transportation of the mesh fabric without the need for manual transportation, thus improving production efficiency; at the same time, the support mechanism prevents the mesh fabric from being too long and causing the middle of the mesh fabric to dent, thereby ensuring the quality of the mesh fabric after welding.

[0029] 6. The loading and unloading mechanism designed in this technical solution is used for loading and unloading the central tube. The pressing mechanism presses one end of the mesh fabric onto the central tube at the upper end of the supporting rotating mechanism. The welding mechanism welds one end of the mesh fabric to the central tube. Then, the supporting rotating mechanism drives the central tube to rotate so that the mesh fabric is wrapped around the central tube. Finally, the welding mechanism welds the other end of the mesh fabric to the central tube. There is no need to manually wind the mesh fabric, which improves production efficiency and production quality. Attached Figure Description

The driving end of the adjusting element 235 is connected to the slide block 234, which is used to drive the slide block 234 to slide up and down on the guide rod 233. By driving the slide block 234 to slide on the guide rod 233 through the adjusting element 235, the slide block 234 drives the second roller 232 to move up and down, thereby adjusting the distance between the second roller 232 and the first roller 231. After the distance between the second roller 232 and the first roller 231 is increased by the adjusting element 235, it is easier for the end of the mesh fabric 100 to pass through. After the mesh fabric 100 passes through, the distance between the second roller 232 and the first roller 231 is decreased by the adjusting element 235, thereby clamping the mesh fabric 100 to achieve transportation.

[0054] The drive assembly includes: a drive element 251, which is a motor or rotary cylinder, mounted on the frame 1; a sprocket and chain assembly 252 (including two sprockets and a chain connecting the two sprockets, the two sprockets being respectively connected to the end of the first roller 231 and the drive end of the drive element 251), which is respectively connected to the drive end of the drive element 251 and the end of the first roller 231 of one of the sets of conveying rollers 23; the ends of two adjacent first rollers 231 are connected by a sprocket and chain assembly 253 (including two sprockets and a chain); when the drive element 251 drives one of the first rollers 231 to rotate through the sprocket and chain assembly 252, the first roller 231 is driven by the sprocket and chain assembly 252. The second group 253 drives the adjacent first roller 231 to rotate, thereby enabling all the conveying roller groups 23 to work and transport the mesh fabric 100; or, the drive assembly one includes: a plurality of drive components 251, which are motors or rotary cylinders, corresponding to a plurality of first rollers 231; a plurality of sprocket and chain groups 252, which are respectively connected to the drive end of the corresponding drive component 251 and the end of the corresponding first roller 231; one drive component 251 and one sprocket and chain group 252 drive the corresponding conveying roller group 23 to work, and each conveying roller group 23 is driven by its corresponding drive component 251 and sprocket and chain group 252.

[0055] Combination Figures 2-4The feeding device 2 also includes a limiting mechanism, which is installed on the frame 1 and is used to limit the mesh fabric 100 in the conveyor roller mechanism 22 to prevent misalignment of the mesh fabric 100 after multiple layers are stacked during transportation. The limiting mechanism includes several limiting blocks 261, which are installed on both sides of the pad 24 of the conveyor roller mechanism 22 and are used to movably abut against the sides of the mesh fabric 100 located on the upper end of the pad 24, thereby ensuring that the left and right edges of the mesh fabric 100 after multiple layers are stacked are aligned during transportation to prevent misalignment. The pad 24 has a strip hole 241, and the limiting blocks 261 are fixed by fasteners (screws or bolts). In this technical solution, a connecting block is provided at the lower end of the pad 24 to connect with the fixing component 1. The limiting block 261 and the connecting block are clamped on the upper and lower end faces of the pad 24, thereby fixing the position of the limiting block 261. By adjusting the position of the fixing component 1 in the strip hole 241, the position of the limiting block 261 installed on the pad 24 is adjusted, thereby adjusting the distance between the limiting blocks 261 at both ends of the pad 24. This ensures that when feeding mesh fabrics 100 of different widths, the limiting blocks 261 can abut against both sides of the mesh fabric, thereby ensuring that the edges of the multi-layered mesh fabrics 100 can be aligned and avoiding misalignment.

[0056] like Figure 4 As shown, the feeding device 2 also includes: a spot welding mechanism 27, which is mounted on the frame 1 and used to spot weld the multi-layer mesh 100 in the conveying roller mechanism 22, thereby avoiding misalignment of the mesh edges; the spot welding mechanism 27 includes: a bracket 271, which is mounted on the frame 1 and located at the side end of the pad 24 of the conveying roller mechanism 22; a first electrode, which is mounted on the bracket 271 and used to support the lower end of the mesh 100 located at the lowest end; a welding torch 273, which is slidably mounted on the bracket 271 (a cylinder is provided at the upper end of the bracket 271, and the driving end of the cylinder is connected to the welding torch 273), and the welding torch 273 can move toward or away from the first electrode; a second electrode, which is mounted on The welding torch 273 is used to press the upper mesh 100 against the lower mesh 100 to weld the multiple meshes 100 together. The pad 24 of the conveying roller mechanism 22 is provided with a clearance opening 242. The side edge of the mesh 100 is movably placed at the upper end of the clearance opening 242. The second electrode is located above the clearance opening 242 and extends movably into the clearance opening 242. The first electrode is located below the clearance opening 242 or inside the clearance opening 242. The first and second electrodes are used to weld the mesh 100 located at the clearance opening 242. The specific structure of the spot welding mechanism 27 can be found in Chinese Patent CN202210324741.X, and will not be described in detail here.

[0057] Combination Figure 5 and Figure 6The cutting mechanism 3 includes: a support frame 31, which is mounted on the frame 1 and located beside the discharge end of the conveying roller mechanism 22; a guide rail 32, which is vertically mounted on the support frame 31; a blade 33, which is slidably mounted on the guide rail 32 via a slider, and the blade 33 is connected to a mounting plate, which is slidably connected to the guide rail 32 via the slider; a crossbeam 34, whose two ends are respectively connected to the two ends of the blade 33 via a connecting plate 341; and a second blade 35, which is slidably mounted on the guide rail 32 via a slider and located between the crossbeam 34 and the blade. Between blade 33 and blade 35, a cutting zone 30 is formed. Blade 35 is connected to mounting plate 2, which is slidably connected to guide rail 32 via slider 2. Drive component 36, which is a cylinder or linear motor, is mounted on crossbeam 34, and its drive end is movably connected to blade 35. It is used to drive blade 35 to move closer to or away from blade 33, thereby cutting the mesh 100 located in the cutting zone 30. When the drive end of drive component 36 drives blade 35 to move toward blade 33, drive component 36 will exert force on crossbeam 34. The reaction force causes the crossbeam 34 to move away from the second blade 35, which in turn drives the first blade 33 to move closer to the second blade 35, thus bringing the second blade 35 and the first blade 33 closer together and cutting the mesh 100. The limiting member 311, mounted on the support frame 31, movably abuts against the lower end of the second blade 35, limiting its sliding on the guide rail 32. After the lower end of the second blade 35 abuts against the limiting member 311, the second blade 35 is in its initial position. Alternatively, the cutting mechanism 3 includes: a support frame 31. The first blade 33 is mounted on the frame 1 and located beside the discharge end of the conveying roller mechanism 22; the second blade 35 is slidably mounted on the support frame 31 via the first slider; the third blade 35 is slidably mounted on the support frame 31 via the second slider, and a cutting zone 30 is formed between the second blade 35 and the first blade 33; the fourth drive component 36 is a cylinder or a linear motor, which is mounted on the support frame 31, and the drive end of the second drive component 36 is movably connected to the second blade 35, for driving the second blade 35 to move closer to or away from the first blade 33, thereby cutting the mesh 100 located in the cutting zone 30.

[0058] Combination Figure 5 and Figure 6 The frame 1 is equipped with a buffer 37, and the upper end of the buffer 37 is fitted with an elastic element 371 (spring, disc spring or rubber block). The elastic element 371 is used to move and abut against the lower end of the second blade 35, thereby limiting the movement of the second blade 35 on the first guide rail 32, preventing the second blade 35 from colliding with the limiting element 311 due to its excessive weight when returning to the initial position, and reducing noise and wear.

[0059] like Figure 6The support frame 31 is equipped with a driving component 38, which is a cylinder or a linear motor. The driving end of the driving component 38 is connected to a pressure bar 381, which is located above the pad 24 at the discharge end of the conveying roller mechanism 22. The driving component 38 drives the pressure bar 381 to move, so that the pressure bar 381 moves towards the upper end of the pad 24, thereby pressing the mesh fabric 100 onto the pad 24, ensuring that the mesh fabric 100 will not be displaced on the pad 24 when the cutting mechanism 3 cuts the mesh fabric 100.

[0060] Combination Figures 2-4 The storage mechanism 21 includes: several material racks 211, which are installed on the frame 1 and located beside the feeding end of the conveying roller mechanism 22 for storing the mesh fabric 100; a second guide rod 212, which is installed on the frame 1 and located beside the feeding end of the conveying roller mechanism 22 for movably abutting the end face of the mesh fabric 100; several second limit blocks 213, which are installed on the second guide rod 212, and two limit blocks 213 respectively movably abut the two ends of the mesh fabric 100 to ensure the accuracy of the feeding position of the mesh fabric 100; the material rack 211 includes a storage rack, a storage rod and a motor for driving the storage rod to rotate, the middle part of the storage rod is inserted into the mesh fabric roll, and the two ends of the storage rod are rotatably connected to the storage rack, and the mesh fabric 100 is fed to the first set of conveying rollers 23 by driving the storage rod to rotate.

[0061] Combination Figure 1 and Figure 7 The feeding device 4 includes: a traction mechanism 41, which is slidably mounted on the frame 1 for clamping the mesh fabric 100 at the discharge end of the conveying roller mechanism 22; a clamping mechanism 5, which is mounted on the frame 1 between the traction mechanism 41 and the conveying roller mechanism 22 for clamping the mesh fabric 100; several support mechanisms 6, which are mounted on the frame 1 and movably positioned between the traction mechanism 41 and the clamping mechanism 5 for supporting the lower end of the mesh fabric 100 pulled out by the traction mechanism 41, preventing the mesh fabric 100 from being too long and causing the middle part to sag downwards; and a conveying mechanism, which is mounted on the frame 1 for conveying the cut mesh fabric 100 to the welding device 8; and then combined with Figure 9 The traction mechanism 41 includes: a traction slide 42, which is slidably mounted on the frame 1 via a slide rail slider (refer to Chinese Patent CN202222838629.6); and a second drive assembly 43, which is movably connected to the frame 1 and the traction slide 42 and is used to drive the traction slide 42 to approach or move away from the discharge end of the conveying roller mechanism 22. The second drive assembly 43 is a transmission connection between a motor and a gear rack, which is prior art. The specific structure of the second drive assembly 43 can be found in Chinese Patent CN202121454289.6, and will not be described in detail here.

[0062] The traction gripper 44 (a pneumatic or electric gripper) is slidably mounted on the traction slide table 42 via a slide rail slider or guide rod, and is used to clamp the end of the mesh fabric 100. The drive component nineteen 45 (a cylinder or linear motor) is mounted on the traction slide table 42, and the drive end of the drive component nineteen 45 is connected to the traction gripper 44, and is used to drive the traction gripper 44 to slide on the traction slide table 42. After the drive component two 43 brings the traction slide table 42 close to the discharge end of the conveying roller mechanism 22, and the traction gripper 44 clamps the end of the mesh fabric 100, the drive component two 43 drives the traction slide table 42 to move on the frame 1, so that the traction slide table 42 moves away from the conveying roller mechanism 22, thereby pulling out the mesh fabric 100.

[0063] Combination Figure 7 , Figure 13 and Figure 15 The support mechanism 6 includes: a drive component 61 (a cylinder or linear motor) mounted on the frame 1; a swing arm 62, the rear end of which is hinged to the frame 1, and the middle part of the swing arm 62 is hinged to the drive end of the drive component 61, the drive component 61 being used to drive the swing arm 62 to rotate on the frame 1; a support plate 63 slidably disposed on the swing arm 62, for supporting the lower end of the mesh 100; and a drive component 64 (a cylinder or linear motor) mounted on the swing arm 62, the drive end of the drive component 64 being movably connected to the support plate 63, for driving the support plate 63 to move on the swing arm 62. During the process of the traction mechanism 41 pulling the mesh 100 away from the feeding device 2, the swing arm 62 rotates and the support plate 63 extends, thereby supporting the lower end of the pulled mesh 100 and preventing the mesh 100 from being pulled too long and causing the middle part to dent.

[0064] like Figure 15 The support mechanism 6 also includes a support platform 65, which is mounted on the frame 1 and located beside the swing arm 62, for supporting the mesh fabric 100 transported by the conveying mechanism, thereby ensuring the flatness of the mesh fabric 100 and preventing the middle part of the mesh fabric 100 from sinking downward.

[0065] Combination Figure 10 and Figure 12The clamping mechanism 5 includes: a second support frame 51, which is mounted on the frame 1; two clamping components 52, which are distributed vertically on the second support frame 51, and a clamping area 58 is formed between the two clamping components 52 for clamping the mesh fabric 100; when the traction mechanism 41 pulls the mesh fabric 100, the mesh fabric 100 will first extend from the clamping area 58 and be clamped by the traction mechanism 41; the clamping component 52 includes: a sixth drive element 53 (a cylinder or linear motor), which is mounted on the second support frame 51; a clamping roller 54, the end of which is rotatably connected to the drive end of the sixth drive element 53; and a seventh drive element 55 (a cylinder or linear motor). The machine is mounted on the support frame 51; the rotation limit block 56 is mounted on the drive end of the drive component 55 and the rotation limit block 56 moves against the clamping roller 54 to limit the rotation of the clamping roller 54; when the drive component 53 drives the corresponding clamping roller 54 to move, the two clamping rollers 54 move closer to each other to clamp the mesh fabric 100 in the clamping area 58. When the cutting mechanism 3 cuts the mesh fabric 100, the clamping mechanism 5 can prevent the mesh fabric from being displaced under the action of the blade, ensuring that the length of the mesh fabric 100 pulled out is fixed, thereby ensuring that the cutting length of the mesh fabric 100 meets the set value.

[0066] like Figure 12 The clamping assembly 52 also includes a clamping plate 57, which is installed on the driving end of the driving component 6 53 and is located next to the clamping roller 54. When the two clamping rollers 54 approach each other, the two clamping plates 57 also approach each other and abut against the upper and lower ends of the mesh fabric 100 respectively, thereby ensuring that the mesh fabric 100 will not be displaced.

The drive assembly 75 connects the support frame 72 and the sliding frame 74, and drives the sliding frame 74 to slide on the support frame 72, so that the sliding frame 74 moves closer to or away from the welding device 8. The drive assembly 75 is a transmission connection between a motor and a gear rack, which is existing technology. The specific structure of the drive assembly 75 can be found in Chinese Patent CN202121454289.6, which will not be described in detail here. At least one gripper assembly 76 is installed on the sliding frame 74 and is used to grip the front end of the mesh fabric 100. This design provides several gripper assemblies 76 arranged along the length of the sliding frame 74. The gripper assembly 76 includes: a drive element 761 (a cylinder, a linear motor, or an electric push rod) installed on the sliding frame 74; and a transport gripper 762 (i.e., a pneumatic gripper) installed on the drive end of the drive element 761 and used to grip the mesh fabric 100.

The drive component 5 773 is a transmission device between the motor and the gear rack. The connection is a prior art. The specific structure of the drive component 773 can be found in Chinese patent CN202121454289.6, and will not be described in detail here. At least one transport gripper 774 (a pneumatic gripper) is mounted on the sliding frame 772 and is used to hold the mesh fabric 100. This technical solution is provided with several transport grippers 774 distributed along the length of the sliding frame 772 to ensure stable clamping with the end of the mesh fabric 100 and to prevent the mesh fabric 100 from curling.

[0069] Combination Figures 10-12 The support frame 2 51 is equipped with a driving component 9 78 (which is a cylinder, an electric push rod, or a linear motor). The driving end of the driving component 9 78 is connected to a top block 781. The top block 781 is located next to the clamping assembly 52 and is used to movably abut against the lower end of the mesh fabric 100. When the driving component 9 78 drives the top block 781 to move toward the mesh fabric 100, the top block 781 abuts against the lower end of the mesh fabric 100 and causes the rear end of the mesh fabric 100 to elastically deform away from the top block 781, so that the end of the mesh fabric 100 can be placed in the transport gripper 2 774, so that the transport gripper 2 774 can hold the mesh fabric 100. When the traction mechanism 41 pulls the mesh fabric 100, the mesh fabric 100 moves below the transport gripper 2 774.

[0070] A sliding frame 3 66 and a driving component 11 67 (a cylinder or linear motor) are slidably mounted on the frame 1. A support mechanism 6 is mounted on the sliding frame 3 66. The driving end of the driving component 11 67 is connected to the sliding frame 3 66 and is used to drive the sliding frame 3 66 to slide on the frame 1, thereby adjusting the height of the support mechanism 6 and ensuring that the support mechanism 6 can be stably supported at the lower end of the mesh 100.

The outer side of the rear end of the gripper chuck 823 is provided with teeth, which mesh with the gear, thereby enabling the drive component 13 824 to drive the gripper chuck 823 to rotate. When the drive component 12 822 drives the sliding seat 821 to approach the support assembly 811, the gripper chuck 823 clamps the end of the central tube 200. The drive component 13 824 drives the gripper chuck 823 to rotate, so that the central tube 200 rotates on the support assembly 811, thereby enabling the mesh fabric 100 to be wound on the outer wall of the central tube 200.

[0073] A mounting base 825 is provided on the upper end of the sliding base 821. The mounting base 825 is slidably connected to the sliding base 821 via a drive assembly 8.

The pusher plate 962 slides on the welding beam 91 and is mounted on the drive end of the drive component 17 961. When the drive component 17 961 drives the pusher plate 962 to move toward the center tube 200, the drive component 6 94, or a cylinder or an electric push rod drives the pusher component 96 to move on the welding beam 91, and the pusher plate 962 abuts against the rear end of the center tube 200, thereby pushing the center tube 200 toward the gripper chuck 823 of the rotating component 82, so that the gripper chuck 823 clamps the center tube 200.

[0079] like Figure 13 and Figure 19 The pressing mechanism 84 includes: a flap 841, the rear end of which is hinged to the frame 1; a drive member 842 (a cylinder or a linear motor) mounted on the frame 1, with the drive end of the drive member 842 hinged to the flap 841, for driving the front end of the flap 841 to move toward or away from the support assembly 811; a plurality of rotating wheels 843 distributed along the length of the flap 841 at the edge of the flap 841, with the rotating wheels 843 hinged to the front end of the flap 841, for moving to abut against the mesh 100 and pressing the mesh 100 against the central tube 200 at the upper end of the support assembly 811; a clearance area 844 is provided between adjacent rotating wheels 843, and the welding mechanism 9 welds the mesh 100 to the central tube 200 through the clearance area 844.

[0080] A control method for a wire mesh welding machine includes the following steps: Step S1: Adjusting the slide block 234 to move upward on the guide rod 233, so that the first roller 231 and the second roller 232 move away from each other to open the conveyor roller group 23; aligning and stacking the multi-layer wire mesh 100 in the storage mechanism 21, so that the front end of the wire mesh 100 passes through the first conveyor roller group 23 until it reaches the second conveyor roller group 23; adjusting the position of the limiting block 261 on the pad 24, so that the limiting block 261 abuts against both sides of the wire mesh 100; adjusting the slide block 234 to move downward on the guide rod 233, so that the first roller 231 and the second roller 232 move closer to each other to close the conveyor roller group 23;

[0081] Step S2: The conveyor roller mechanism 22 transports the front end of the mesh fabric 100 to the cutting mechanism 3; the conveyor roller mechanism 22 extends the front end of the mesh fabric 100 out of the cutting mechanism 3, and the cutting mechanism 3 cuts off the front end of the mesh fabric 100, so that the front ends of the multi-layer mesh fabric 100 are aligned; Steps S1 and S2 are only executed at the beginning of the mesh fabric (during the first feeding), and the subsequent steps S3 to S8 are completed by the machine. Then, after the machine has used up all the mesh fabric 100, steps S1 and S2 are executed again.

[0082] Step S3: The traction slide 42 moves toward the cutting mechanism 3, and then the traction gripper 44 clamps the front end of the mesh fabric 100. The traction slide 42 then moves away from the cutting mechanism 3, thereby pulling out the mesh fabric 100. During the process of the traction slide 42 pulling out the mesh fabric 100, the conveying roller mechanism 22 transports the mesh fabric 100 to the cutting mechanism 3 for feeding. The spot welding mechanism 27 performs spot welding on the mesh fabric 100 at set intervals. At the same time, during the process of the traction slide 42 pulling out the mesh fabric 100, the support mechanism 6 opens and supports the lower end of the mesh fabric 100.

[0083] Step S4: After the traction slide 42 pulls the mesh fabric 100 to a set length, the clamping mechanism 5 clamps the rear half of the mesh fabric 100, the cutting mechanism 3 cuts the mesh fabric 100, and the traction slide 42 moves again away from the cutting mechanism 3, so that the rear end of the mesh fabric 100 moves to the clamping mechanism 5; then the first transport component 71 clamps the front end of the mesh fabric 100, and the second transport component 77 clamps the rear end of the mesh fabric 100; the traction gripper 44 releases the mesh fabric 100 and moves away from the mesh fabric 100.

[0084] Step S5: The loading and unloading mechanism loads the central tube 200 onto the supporting rotating mechanism 81. The welding beam 91 moves above the central tube 200. The pusher plate 962 of the pusher assembly 96 descends. The drive assembly 94 drives the pusher plate 962 to abut against one end of the central tube 200 and drives the central tube 200 to move toward the gripper chuck 823. The gripper chuck 823 clamps the other end of the central tube 200. The pusher plate 962 rises and leaves the central tube 200. The inner support rod 952 is inserted into the central tube 200. Step S5 can be executed simultaneously with steps S1-S4. That is, when steps S1-S4 are executed, step S5 can be executed synchronously. Of course, step S5 can also be executed after steps S1-S4 are completed.

[0085] Step S6: Conveying component 1 71 and conveying component 2 77 move the mesh 100 toward the central tube 200, so that the side end of the mesh 100 crosses the vertical plane where the center line of the central tube 200 is located; the pressing mechanism 84 presses the end of the mesh 100 onto the central tube 200; the third electrode 932 of welding component 1 93 moves to the clearance area 844 for welding, and at the same time the inner support rod 952 moves with welding component 1 93, so that the fourth electrode 953 corresponds to the third electrode 932 and welds; the conveying component 1 71 and conveying component 2 77 release the two ends of the mesh 100 and move to the initial position; after step S6 is completed, the machine returns to and re-executes step S3 until the raw material of the mesh 100 in the storage mechanism 21 is used up, and then step S1 is re-executed;

[0086] Step S7: After one side of the mesh 100 is welded to the central tube 200, the drive component 13 824 drives the gripper chuck 823 to rotate at a set angle, so that the mesh 100 is wound around the central tube 200, and the other side of the mesh 100 is placed between the third electrode 932 and the fourth electrode 953. Then the third electrode 932 of the welding component 1 93 moves to the clearance area 844 to perform welding, thereby realizing the winding and welding of the mesh 100 to the central tube 200.

[0087] Step S8: After the mesh 100 is welded onto the central tube 200, the welding beam 91 drives the welding component 1 93 away from the upper end of the central tube 200, the inner support rod 952 of the welding component 2 95 leaves the central tube 200, the flip plate 841 of the clamping mechanism 84 is lifted, the gripper chuck 823 releases the central tube 200, and the lifting component 83 lifts the central tube 200 from the support component 811; the loading and unloading mechanism unloads the central tube 200 with the welded mesh 100.
