Description

Technical Field

[0001] This invention belongs to the technical field of shelving mesh welding device and production method, and particularly relates to a shelving mesh welding device and a method for preparing shelving mesh using the device. Background Technology

[0002] The unfolded shelving mesh panel consists of corrugated wires and supporting ribs at the bottom of the corrugated wires. Side ribs welded to the corrugated wires are located on both sides, and end ribs welded to the supporting ribs are located at both ends of the corrugated wires. Currently, the production of shelving mesh panels mainly uses manual welding: first, the straightened wires are bent in a corrugated mold; then, the supporting ribs and side ribs are placed on top of the corrugated wires; finally, the end ribs are placed on top of the supporting ribs and side ribs, and then welded with a welding gun. This method has the following drawbacks: First, manually winding the wires around the stakes and bending them into corrugated wires is labor-intensive and inefficient. During bending, the wires are prone to bending, and the welds are prone to cracking, resulting in poor connection strength. Second, uneven tension during winding causes unequal distances between adjacent corrugated wires, affecting the aesthetics of the shelving and making it easy for goods to fall out.

[0009] The second technical problem to be solved by the present invention is to provide a method for producing shelf mesh panels using the above-mentioned shelf mesh panel welding device.

[0010] To solve the above problems, the technical solution adopted by the present invention for preparing the shelf mesh using the above-mentioned shelf mesh welding device is as follows:

[0011] The method includes the following steps:

[0012] The first step is to weld the end reinforcement.

[0013] The straightened trailing wire is inserted between two opposite welding heads of the welding mechanism. The horizontal wire storage and feeding mechanism feeds the horizontal wire to the welding head position above the trailing wire. The welding mechanism then welds the two horizontal wires onto the trailing wire in sequence.

[0014] The second step is to prepare the wavy yarn.

[0015] first step

[0016] The filament is straightened by a straightening mechanism;

[0017] Step (2): Clamp the end of the filament with clamps.

[0018] After the filament is passed around the right side of the first right bend post and the second right bend post, it is inserted into the clamp and the clamp clamps the filament.

[0019] Step (3): Move the frame backward along the first slide rail, while the left bending column moves to the right.

[0020] The first servo motor is activated, causing the first gear to rotate on the first rack track. The moving frame moves along the first slide rail to the rear of the fixed frame. The second rack track above the first gear, along with the first right bending column and the first right bending column fixed on the second rack track, move backward relative to the moving frame. The speed at which the first right bending column and the first right bending column move backward relative to the fixed frame is twice the speed at which the moving frame moves backward relative to the fixed frame. As the moving frame moves backward, the left bending column and the left bending column on the moving frame move downward, causing the top of the left bending column to be horizontal. The surface is lower than the horizontal plane where the lower end of the filament is located. The second servo motor drives the left bending column to move to the right. When the left bending column reaches the right side of the filament, the left bending column is pushed up, so that the horizontal plane where the top of the left bending column is located is higher than the horizontal plane where the lower end of the filament is located. At this time, the distance between the leftmost tangent point of the left bending column and the filament and the rightmost tangent point of the second right bending column and the filament is equal to the filament length between the center positions of two adjacent bends of the wavy filament. The distance between the leftmost tangent point of the left bending column and the filament and the rightmost tangent point of the first right bending column and the filament is equal to the filament length between the center positions of two adjacent bends of the wavy filament.

[0021] Step (4): Move the frame forward along the first slide rail, while the left bending column moves to the left to complete the wavy wire bending.

[0022] The first servo motor is activated, causing the first gear to rotate on the first rack track. The moving frame moves forward along the first slide rail towards the fixed frame. The second rack track above the first gear, along with the first right bending column and the first right bending column fixed to the second rack track, move forward relative to the moving frame. The forward speed of the first right bending column and the first right bending column relative to the fixed frame is twice the forward speed of the moving frame relative to the fixed frame. The left bending column and the left bending column on the moving frame move forward with the moving frame. While moving forward, the left bending column pulls the filament to bend to the left. During the movement, the trajectory of the first right bending column moving forward and the trajectory of the left bending column moving forward and to the right satisfy the following conditions: at any position during the movement, the distance between the leftmost point of tangency between the left bending column and the filament and the rightmost point of tangency between the second right bending column and the filament is always equal; the distance between the rightmost point of tangency between the first right bending column and the filament and the leftmost point of tangency between the left bending column and the filament is always equal; the filament is bent into two opposing "U"-shaped bends with their ends connected.

[0023] Step (5): Send the bent, wavy filament forward.

[0024] The upper comb plate is pressed down, causing the bent wavy wire to enter the upper comb groove of the upper comb plate. The lower comb plate moves downward, causing the bent wavy wire to disengage from the lower comb groove. The upper comb plate drives the bent filament forward by the length of two "U" shaped filaments. At this time, the 90-degree bend of the filament just passes around the second right bend post from the right side.

[0025] Step (six): Reset the upper comb plate.

[0026] The lower comb plate moves upward, allowing the bent wavy filaments to enter the lower comb groove. The upper comb plate moves upward, and the filaments move out of the upper comb groove. The upper comb plate moves backward, resetting the length of the distance between two "U"-shaped filaments.

[0027] Step (7): Continue bending the thin wires.

[0028] Repeat step (two) to step (six) until the length of the wavy silk reaches the required length;

[0029] Step (8): Cut the wavy wire.

[0030] The aligning cylinder drives the aligning plate to move to the right, and the aligning plate pushes the corrugated wire to the right, so that the right end of the corrugated wire hits the side of the cutting limit baffle, and the cutting mechanism cuts the corrugated wire that meets the length requirements.

[0031] The third step is to feed the cut wavy yarn forward.

[0032] The top rod of the clamping cylinder presses down, and the gripper clamps the two end ribs at the front end of the corrugated wire. The forward and backward servo motor drives the clamping frame to move forward. When the clamping frame moves forward, the two end ribs at the front end of the corrugated wire are sent to the welding head below the drag rib and the side stop rib. The welding mechanism welds the drag rib, the side stop rib and the two end ribs at the front end of the corrugated wire together. The top rod of the clamping cylinder resets, the gripper releases the end ribs, and the forward and backward servo motor rotates in the opposite direction, driving the gripper to reset backward.

[0033] The fourth step is to continue feeding the corrugated wire forward and welding it to the drag bar and side retaining bar.

[0034] The top rod of the clamping cylinder continues to press down, and the gripper clamps the two unwelded end ribs at the front end of the corrugated wire. As the clamping frame moves forward, the two end ribs at the front end of the corrugated wire are sent to the welding head below the drag rib and the side baffle rib. The welding mechanism welds the drag rib, the side baffle rib and the two end ribs at the front end of the corrugated wire together. The top rod of the clamping cylinder resets, the gripper releases the end ribs and resets backward, and the mesh pulling mechanism pulls the mesh forward. The corrugated wire is repeatedly sent forward and welded with the drag rib and the side baffle rib until all the corrugated wires are welded with the drag rib and the side baffle rib.

[0035] Step 5: Weld the two end ribs at the back of the shelf and the two end ribs at the front of the adjacent mesh panels.

[0036] The front mesh pulling mechanism pulls the mesh sheet, and the horizontal wire storage and feeding mechanism feeds the four end ribs to the welding head position above the drag rib in sequence. The welding mechanism then welds the four end ribs to the top of the drag rib in sequence.

[0037] Step 6: Cut the side bracing between two adjacent shelving unit panels.

[0038] As the net is pulled forward, the push rod at the lower end of the side baffle cutting cylinder presses down, and the two end presser feet on both sides press the side baffles at both ends together. The side baffle cutter cuts the side baffles between two adjacent shelf nets.

[0039] Step 7: Cut the reinforcing bars between two adjacent shelving unit panels.

[0040] When the end of the shelving mesh passes the drag bar cutter on the drag bar cutting frame, the push rod of the drag bar cutting cylinder drives the drag bar cutter to press down and cut the drag bar connecting the adjacent mesh panels.

[0041] Step 8: Continue with the steps above until completion.

[0042] Repeat steps two through seven until the process is complete.

[0043] As a further improvement to the above method,

[0044] In step (iv), the moving frame moves forward along the first slide rail, while the left bending column moves to the left. After completing the bending of the corrugated wire, the corrugated wire shaping step is performed first, followed by step (v), which involves feeding the bent corrugated wire forward. The corrugated wire shaping step includes:

[0045] The first shaping cylinder drives the inverted "U"-shaped first shaping fork downwards. The inner sides of the two sides of the first shaping fork move downwards along the outer sides of the two bent filaments, bringing the bent filaments closer to the center to prevent them from spreading out to the sides. The second shaping cylinder drives the second shaping fork to insert between the two adjacent bent filaments, prying the bent filaments apart to the sides to prevent them from moving closer to the center. After shaping, the first shaping cylinder drives the first shaping fork, and the second shaping cylinder drives the second shaping fork to quickly lift up.

[0046] Compared with the prior art, the storage rack mesh welding device and the method for preparing storage rack mesh provided by the present invention have the following advantages: Firstly, since it includes a corrugated wire bending mechanism, a corrugated wire feeding mechanism, a warp wire conveying mechanism, a cross wire storage and feeding mechanism, a welding mechanism, a mesh pulling mechanism, a side rib cutting mechanism, and a drag rib cutting mechanism, the corrugated wire bending mechanism includes a fixed frame and a movable frame. A first slide rail in the front-rear direction is provided on the fixed frame, and a slide groove that engages with the first slide rail is provided on the movable frame. A first rack and pinion track is provided on the fixed frame on the side of the first slide rail, and a first servo motor is provided on the movable frame. A first gear that matches the first rack and pinion track is provided on the power shaft of the first servo motor. A second rack rail matching the first gear is provided on the movable frame above the first gear. A first right-bending column frame is provided on the second rack rail, and a first right-bending column is provided on the first right-bending column frame. A transverse slide rail is provided in front of the movable frame, and a left-bending column frame that can move left and right along the transverse slide rail is provided on the transverse slide rail. A left-bending column lifting mechanism is provided on the left-bending column frame, and a left-bending column is provided on top of the left-bending column lifting mechanism. The left-bending column frame is connected to the movable frame via a second servo motor. A second right-bending column is provided near the rear of the fixed frame, and a clamp is provided on the left side of the second right-bending column. Two parallel lower comb teeth in the front-back direction are provided on the fixed frame. The plate has an upward-opening lower comb tooth groove on the lower comb tooth plate. The lower comb tooth plate is connected to the fixed frame via a lower comb tooth plate lifting mechanism. An upper comb tooth plate frame is provided above the lower comb tooth plate. Two parallel upper comb tooth plates that can move back and forth along the upper comb tooth plate frame are provided on the upper comb tooth plate frame. The upper comb tooth plate has an upward-opening upper comb tooth groove. The upper comb tooth plate frame is connected to the fixed frame via an upper comb tooth plate frame lifting mechanism. A corrugated wire cutting mechanism is provided on the left side of the left upper comb tooth plate. A cutting limit baffle is provided on the fixed frame to the right of the second right bending column. A aligning cylinder is provided to the left of the cutting mechanism, and an aligning plate is provided to the right of the aligning cylinder. The corrugated wire feeding mechanism includes a clamping frame and a positioning... A clamping cylinder is mounted on a clamping frame, with its push rod connected to a gripper. A wire feeding track is provided on the fixed frame, allowing the clamping frame to move back and forth along the wire feeding track. A forward / backward servo motor is provided between the clamping frame and the fixed frame. The horizontal wire storage and feeding mechanism includes a storage hopper and a horizontal wire feeding mechanism. The mesh pulling mechanism includes a mesh pulling frame and a mesh pulling servo motor. A mesh pulling trolley is mounted on the mesh pulling frame. The side rib cutting mechanism is mounted on the mesh pulling trolley and includes a side rib cutting frame. A side rib cutting cylinder is mounted on the side rib cutting frame. Two end pressure feet are provided on the push rod at the lower end of the side rib cutting cylinder, and a side rib cutter is provided between the two end pressure feet.The drag bar cutting mechanism is located at the front end of the mesh frame. The drag bar cutting mechanism includes a drag bar cutting frame body, on which a drag bar cutting cylinder with a drag bar cutter at its lower end is installed. The straightened drag bar tip is inserted between two opposing welding heads of the welding mechanism. The horizontal wire storage and feeding mechanism feeds the horizontal wire to the welding head position above the drag bar. The welding mechanism sequentially welds two horizontal wires above the drag bar. Then, a corrugated wire is prepared. The top rod of the clamping cylinder presses down, and the jaws clamp the two end ribs at the very front of the corrugated wire. As the clamping frame moves forward, the two end ribs at the very front of the corrugated wire are fed to the welding head below the drag bar and side guard ribs. The welding mechanism welds the drag bar, side guard ribs, and the two end ribs at the front of the corrugated wire together. The top rod of the clamping cylinder resets, the jaws release the end ribs, and return to their original position. The top rod of the clamping cylinder continues to press down, and the jaws clamp the two unwelded end ribs at the front of the corrugated wire. As the clamping frame moves forward, the two end ribs at the very front of the corrugated wire are fed to the welding head below the drag rib and side guard rib. The welding mechanism welds the drag rib, side guard rib, and the two end ribs at the front of the corrugated wire together. The top rod of the clamping cylinder resets, the jaws release the end ribs, and reset backward. The mesh pulling mechanism pulls the mesh forward, repeatedly feeding the corrugated wire forward and welding it with the drag rib and side guard rib until all the corrugated wires are welded to the drag rib and side guard rib. The mesh pulling mechanism pulls the mesh forward, and the horizontal wire storage and feeding mechanism feeds the four end ribs sequentially to the welding head position above the drag rib. The welding mechanism welds the four end ribs sequentially above the drag rib. Simultaneously with pulling the mesh forward, the top rod at the lower end of the side guard rib cutting cylinder presses down, and the two end ribs located on both sides... The end presser feet press the side retaining ribs at both ends firmly, and the side retaining rib cutter cuts the side retaining ribs between two adjacent shelving mesh panels. When the end of the shelving mesh panel passes the dragging rib cutter on the dragging rib cutting frame, the push rod of the dragging rib cutting cylinder drives the dragging rib cutter downward, cutting the dragging ribs connecting the adjacent mesh panels. Continue the above steps until completion. In this way, the shelving mesh panel is completed on the entire production line, with good welding quality and uniform wavy wire arrangement. Secondly, since the shelving rib cutting track is set on the mesh pulling trolley, and a track groove matching the side retaining rib cutting track is set below the side retaining rib cutting frame, the two side retaining rib cutting frames are adjusted according to the different lengths of the mesh panels. The track position makes it more convenient to use; thirdly, because a first shaping cylinder is set on the fixed frame above the second right bending column, and a trapezoidal first shaping block (wider at the top and narrower at the bottom) is set on the top rod below the first shaping cylinder, when the left bending column is at the leftmost position, a second shaping cylinder is set on the fixed frame above the left bending column, and a second shaping block is set on the top rod below the second shaping cylinder. A notch (wider at the bottom and narrower at the top) is set below the second shaping block. The bent filament is easily deformed under its own tension, and is reshaped by the first and second shaping blocks, making the bent wavy wire less prone to deformation during forward movement.

A notch 65, which is wider at the bottom and narrower at the top, is installed below the second shaping block 64. The bent filament is easily deformed under the tension of the filament itself. It is reshaped by the first shaping block and the second shaping block, so that the bent wavy filament is not easily deformed during the forward movement.

[0069] A method for producing corrugated wire using the above-mentioned shelving mesh welding device includes the following steps:

[0070] The first step is to weld the end reinforcement.

[0071] The straightened trailing rod 2 is inserted between the two opposite welding heads of the welding mechanism 9. The horizontal wire storage and feeding mechanism 8 feeds the horizontal wire to the welding head position above the trailing rod. The welding mechanism 9 welds the two horizontal wires on the top of the trailing rod in sequence.

[0072] The second step is to prepare the wavy yarn.

[0073] first step

[0074] The filament is straightened by a straightening mechanism;

[0075] Step (2): Clamp the end of the filament with clamps.

[0076] After the filament is passed around the right side of the first right bending post 22 and the second right bending post 29, it is inserted into the clamp 30, and the clamp 30 clamps the filament tightly.

[0077] Step (3): The movable frame 14 moves backward along the first slide rail 15, while the left bending column 27 moves to the right.

[0078] The first servo motor 18 is activated, causing the first gear 19 to rotate on the first rack track 17. The moving frame 14 moves along the first slide rail 15 behind the fixed frame 13. The second rack track 20 above the first gear 19, and the first right bending column 21 and first right bending column 22 fixed on the second rack track 20, move backward relative to the moving frame 14. The speed at which the first right bending column 21 and first right bending column 22 move backward relative to the fixed frame 14 is twice the speed at which the moving frame 14 moves backward relative to the fixed frame 13. As the moving frame 14 moves backward, the left bending column 25 and left bending column 27 on the moving frame 14 move downward. The horizontal plane at the top of the left bending column 27 is lower than the horizontal plane at the bottom of the filament. The second servo motor 28 drives the left bending column 27 to move to the right. When the left bending column 27 reaches the right side of the filament, the left bending column 27 is pushed up, so that the horizontal plane at the top of the left bending column 27 is higher than the horizontal plane at the bottom of the filament. At this time, the distance between the leftmost tangent point of the left bending column 27 and the filament and the rightmost tangent point of the second right bending column 29 and the filament is equal to the length of the filament between the center positions of two adjacent bends of the wavy filament. The distance between the leftmost tangent point of the left bending column 27 and the filament and the rightmost tangent point of the first right bending column 22 and the filament is equal to the length of the filament between the center positions of two adjacent bends of the wavy filament.

[0079] Step (4): Move the frame forward along the first slide rail, while the left bending column moves to the left to complete the wavy wire bending.

[0080] When the first servo motor 18 is activated, the first gear 19 rotates, causing it to rotate on the first rack track 17. The moving frame 14 moves forward along the first slide rail 15 towards the fixed frame 13. The second rack track 20 above the first gear 19, and the first right bending column 21 and the first right bending column 22 fixed on the second rack track 20, move forward relative to the moving frame 14. The forward movement speed of the first right bending column 21 and the first right bending column 22 relative to the fixed frame 13 is twice the forward movement speed of the moving frame relative to the fixed frame. The left bending column 25 and the left... As the moving frame 14 moves forward, the left bending column 27 pulls the filament to bend to the left. During the movement, the trajectory of the first right bending column 22 moving forward and the trajectory of the left bending column 27 moving forward and to the right satisfy the following conditions: at any position during the movement, the distance between the leftmost point of tangency between the left bending column 27 and the filament and the rightmost point of tangency between the second right bending column 29 and the filament is always equal; the distance between the rightmost point of tangency between the first right bending column 22 and the filament and the leftmost point of tangency between the left bending column 27 and the filament is always equal; the filament is bent into two opposing "U"-shaped bends with their ends connected.

[0081] Step (5): Send the bent, wavy filament forward.

[0082] The upper comb plate 35 is pressed down, causing the bent wavy filament to enter the upper comb groove 36 of the upper comb plate 35. The lower comb plate 31 moves downward, causing the bent wavy filament to disengage from the lower comb groove 32. The upper comb plate 35 drives the bent filament to move forward by the length of two "U" shaped filaments. At this time, the 90-degree bend of the filament just passes around the second right bend post 29 from the right side of the second right bend post.

[0083] Step (six): Reset the upper comb plate.

[0084] The lower comb plate 31 is pushed up, so that the bent wavy wire enters the lower comb groove 32. The upper comb plate 35 moves up, and the filament moves out from the upper comb groove 36 of the upper comb plate 35. The upper comb plate 35 moves backward and the length of the distance between the two "U" shaped filaments is reset.

[0085] Step (7): Continue bending the thin wires.

[0086] Repeat step (two) to step (six) until the length of the wavy silk reaches the required length;

[0087] Step (8): Cut the wavy wire.

[0088] The aligning cylinder 40 drives the aligning plate 41 to move to the right. The aligning plate 41 pushes the corrugated wire to the right, so that the right end of the corrugated wire hits the side of the cutting limit baffle 39. The corrugated wire cutting mechanism 38 cuts the corrugated wire with the required length.

[0089] The third step is to feed the cut wavy yarn forward.

[0090] The top rod of the clamping cylinder 43 is pressed down, and the gripper 44 clamps the two end ribs at the front end of the corrugated wire. The forward and backward servo motor 46 drives the clamping frame 42 to move forward. When the clamping frame 42 moves forward, the two end ribs at the front end of the corrugated wire are sent to the welding head below the drag rib and the side baffle rib. The welding mechanism 9 welds the drag rib 2, the side baffle rib 3 and the two end ribs 4 at the front end of the corrugated wire 1 together. The top rod of the clamping cylinder 43 is reset, the gripper 44 releases the end ribs, and the forward and backward servo motor 46 rotates in the opposite direction, driving the gripper 44 to reset backward.

[0091] The fourth step is to continue feeding the corrugated wire forward and welding it to the drag bar and side retaining bar.

[0092] The top rod of the clamping cylinder 43 continues to press down, and the jaws 44 clamp the two unwelded end ribs at the front end of the corrugated wire. As the clamping frame moves forward, the two end ribs at the front end of the corrugated wire are sent to the welding head below the drag rib and the side baffle rib. The welding mechanism 9 welds the drag rib, the side baffle rib and the two end ribs at the front end of the corrugated wire together. The top rod of the clamping cylinder returns to its original position, the jaws release the end ribs and return to their original position. The mesh pulling mechanism pulls the mesh forward and repeats the process of sending the corrugated wire forward and welding it with the drag rib and the side baffle rib until all the corrugated wires are welded with the drag rib and the side baffle rib.

[0093] Step 5: Weld the two end ribs at the back of the shelf and the two end ribs at the front of the adjacent mesh panels.

[0094] The mesh pulling mechanism 10 pulls the mesh sheet in front, and the horizontal wire storage and feeding mechanism 8 feeds the four end ribs to the welding head position above the drag rib in sequence. The welding mechanism 9 welds the four end ribs to the drag rib 2 in sequence.

[0095] Step 6: Cut the side bracing between two adjacent shelving unit panels.

[0096] As the net is pulled forward, the top rod at the lower end of the side baffle cutting cylinder 53 is pressed down, and the two end pressure feet 54 on both sides press the side baffles 3 at both ends, and the side baffle cutter cuts the side baffles 3 between the two adjacent shelf nets.

[0097] Step 7: Cut the reinforcing bars between two adjacent shelving unit panels.

[0098] When the end of the shelving mesh passes the drag bar cutter 57 on the drag bar cutting frame 53, the push rod of the drag bar cutting cylinder 58 drives the drag bar cutter 57 to press down and cut the drag bar connecting the adjacent mesh.

[0099] Step 8: Continue with the steps above until completion.

[0100] Repeat steps two through seven until the process is complete.

After the filament is passed around the right side of the first right bend post and the second right bend post, it is inserted into the clamp and the clamp clamps the filament. Step (3): Move the frame backward along the first slide rail, while the left bending column moves to the right. The first servo motor is activated, causing the first gear to rotate on the first rack track. The moving frame moves along the first slide rail to the rear of the fixed frame. The second rack track above the first gear, along with the first right bending column and the first right bending column fixed on the second rack track, move backward relative to the moving frame. The speed at which the first right bending column and the first right bending column move backward relative to the fixed frame is twice the speed at which the moving frame moves backward relative to the fixed frame. As the moving frame moves backward, the left bending column and the left bending column on the moving frame move downward, causing the top of the left bending column to be horizontal. The surface is lower than the horizontal plane where the lower end of the filament is located. The second servo motor drives the left bending column to move to the right. When the left bending column reaches the right side of the filament, the left bending column is pushed up, so that the horizontal plane where the top of the left bending column is located is higher than the horizontal plane where the lower end of the filament is located. At this time, the distance between the leftmost tangent point of the left bending column and the filament and the rightmost tangent point of the second right bending column and the filament is equal to the filament length between the center positions of two adjacent bends of the wavy filament.

During the movement, the trajectory of the first right bending column moving forward and the trajectory of the left bending column moving forward and to the right satisfy the following conditions: at any position during the movement, the distance between the leftmost point of tangency between the left bending column and the filament and the rightmost point of tangency between the second right bending column and the filament is always equal; the distance between the rightmost point of tangency between the first right bending column and the filament and the leftmost point of tangency between the left bending column and the filament is always equal; the filament is bent into two opposing "U"-shaped bends with their ends connected. Step (5): Send the bent, wavy filament forward. The upper comb plate is pressed down, causing the bent wavy wire to enter the upper comb groove of the upper comb plate. The lower comb plate moves downward, causing the bent wavy wire to disengage from the lower comb groove. The upper comb plate drives the bent filament forward by the length of two "U" shaped filaments. At this time, the 90-degree bend of the filament just passes around the second right bend post from the right side. Step (six): Reset the upper comb plate. The lower comb plate moves upward, allowing the bent wavy filaments to enter the lower comb groove. The upper comb plate moves upward, and the filaments move out of the upper comb groove.

The top rod of the clamping cylinder resets, the gripper releases the end ribs, and the forward and backward servo motor rotates in the opposite direction, driving the gripper to reset backward. The fourth step is to continue feeding the corrugated wire forward and welding it to the drag bar and side retaining bar. The top rod of the clamping cylinder continues to press down, and the gripper clamps the two unwelded end ribs at the front end of the corrugated wire. As the clamping frame moves forward, the two end ribs at the front end of the corrugated wire are sent to the welding head below the drag rib and the side baffle rib.
