Description

Technical Field

[0001] This invention relates to the field of bath sponge production equipment, and more particularly to a bath sponge production equipment. Background Technology

[0002] Currently, the production of bath sponges mostly relies on manual processing. Workers need to sequentially perform operations such as pulling and stacking net bags, cutting net bags, making loops, tying net bags, and shaping the sponges. This process involves many repetitive actions of pulling, clamping, cutting, threading, tying, and pulling. Not only are there many steps and the labor intensity is high, but the net bags also need to be manually transferred and repositioned between each step, resulting in poor production continuity.

[0003] In addition, the mesh bags used for bath sponges are soft and easily deformable. During manual processing, the stacking amount of the mesh bags, the binding position, the tightness of the loops, and the pulling degree of the mesh bags are easily affected by the operator's skill level and operating conditions. This results in certain differences in the size, tightness, and fluffiness of different bath sponges, which is not conducive to the consistent production of products.

[0004] Therefore, it is necessary to provide a bath ball production equipment that enables the net bag to complete the stacking and cutting of the pull straps, the preparation of the loop rope, the threading and binding, and the shaping of the flower pattern in sequence on the equipment, and to connect the various processing steps continuously, so as to reduce manual intervention and improve the continuity and stability of the bath ball production process. Summary of the Invention

[0005] The present invention provides a bath bomb production equipment to solve the related technical problems in the background art.

[0006] The technical solution provided by this invention is as follows: A bath ball production equipment, comprising: a frame, a turntable assembly, multiple material loading assemblies, a belt cutting mechanism, a rope welding mechanism, a threading and binding mechanism, and a flower-pulling mechanism.

[0007] Compared with the prior art, the beneficial effects of the present invention are: (1) The bath flower ball production equipment of the present invention, by setting multiple material-carrying components on the turntable along the circumference, and sequentially setting the pull-belt cutting mechanism, the threading and binding mechanism and the flower-pinching mechanism along the rotation path of the material-carrying components, and simultaneously setting the loop welding mechanism and the threading and binding mechanism accordingly, so that the material-carrying components can rotate with the turntable at indexing, and sequentially complete the stacking and cutting of the net bag pull-belt, the preparation and supply of loop rope, the threading and binding, the flower-pinching and shaping and the finished product unloading, thereby integrating multiple processing steps in the bath flower ball production process into the same equipment, reducing manual transfer, positioning and repetitive operations, and improving the continuity and processing efficiency of bath flower ball production.

[0008] (2) The bath ball production equipment of the present invention, by setting the loop rope welding mechanism and the threading and binding mechanism in a corresponding manner, and placing the loop rope receiving position of the threading and binding mechanism below the loop rope output position of the loop rope welding mechanism, can directly convey the closed loop rope made by the loop rope welding mechanism to the threading and binding mechanism; at the same time, through the cooperation of the first threading rod, the second threading rod, the turning component and the tensioning component, the closed loop rope can be unfolded, cross-wound and tightened in the middle of the net bag section on the upper and lower sides, thereby realizing the continuous connection between the closed loop rope preparation and the net bag binding process.

[0009] (3) In the bath flower ball production equipment of the present invention, the flower-pulling mechanism converts the rotational motion of the driving component into the compound motion of the flower-pulling claw through the cooperation of the transmission rod, follower, track groove, slider and slide bar, so that the flower-pulling claw can pass over the top of the material loading component to clamp the net bag according to the preset trajectory and pull the net bag to the side where the flower-pulling mechanism is located; the left flower-pulling component and the right flower-pulling component repeatedly clamp, pull and release the net bags on both sides of the binding position, so that the compressed and stacked net bags gradually unfold to form fluffy bath flower balls, and the flower-pulling trajectory is stable and has good repeatability.

Detailed Implementation

[0012] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0013] This embodiment provides a bath ball production equipment, including: a frame 1, a turntable assembly 2, multiple material loading assemblies 3, a pull-belt cutting mechanism 4, a loop rope welding mechanism 5, a threading and binding mechanism 6, a flower-pinching mechanism 7, a first lifting mechanism 8, and a second lifting mechanism 9; wherein, the pull-belt cutting mechanism 4, the threading and binding mechanism 6, and the flower-pinching mechanism 7 are arranged sequentially along the rotation path of the material loading assembly 3, and the loop rope welding mechanism 5 is arranged correspondingly to the threading and binding mechanism 6, and is used to prepare the closed-loop loop rope required for threading and binding.

[0014] The turntable assembly 2 includes: a hollow rotary table 22 disposed at the bottom of the frame 1, and a turntable 21 connected to the rotating end of the hollow rotary table 22 and located on the frame 1; multiple material-carrying components 3 are arranged at intervals along the circumference of the turntable 21 and can rotate synchronously with the turntable 21; the hollow rotary table 22 can drive the turntable 21 to perform indexing rotation, so that each material-carrying component 3 passes through the tape cutting station, the wire binding station and the twisting station in sequence, and stops at the corresponding station for processing by the corresponding mechanism.

[0015] The turntable 21 has a central clearance opening in the middle, and the hollow rotary table 22 has a hollow area in the middle. A flange 23 is provided in the hollow area of ​​the hollow rotary table 22. The flange 23 is fixedly connected to the frame 1, and the upper part of the flange 23 is connected to the lower base plate 24 located above the hollow rotary table 22. The turntable 21 can rotate relative to the flange 23 and the lower base plate 24. Therefore, during the indexing rotation of the turntable 21, the flange 23 and the lower base plate 24 can remain fixed, thereby providing a fixed installation base for some of the actuators of the wire binding mechanism 6.

[0016] Each material loading assembly 3 includes: two upright rods 31 spaced apart on the turntable 21, and a pressing member 32 slidably disposed on the two upright rods 31; the two upright rods 31 extend vertically, and the continuous mesh bag can be sleeved and compressed and stacked on the outside of the two upright rods 31 after being conveyed downward by the pull belt cutting mechanism 4; the pressing member 32 can slide up and down along the two upright rods 31, thereby lifting and compressing the mesh bag segment from below during the threading and binding process, and pushing the bath ball out from below after the bath ball is formed.

[0017] Each material loading component 3 on the turntable 21 is provided with a lifting through hole 211, which is located below the corresponding pressing component 32; a first lifting mechanism 8 is provided below the station where the threading and binding mechanism 6 is located, and a second lifting mechanism 9 is provided below the station where the twisting mechanism 7 is located.

[0018] The first lifting mechanism 8 includes: a first lifting drive 81, and a first lifting member 82 connected to the lifting end of the first lifting drive 81; when the material loading assembly 3 rotates to the threading and binding station, its corresponding lifting through hole 211 is located between the first lifting member 82 and the lower pressing member 32. The first lifting drive 81 can drive the first lifting member 82 to pass through the lifting through hole 211 and push the lower pressing member 32 from below.

[0019] Specifically, the first lifting drive component 81 includes: a first lifting mechanism mounting plate 811 connected to the bottom of the frame 1, a first lifting mechanism lead screw 812 rotatably connected to the first lifting mechanism mounting plate 811, a first lifting mechanism lead screw nut 813 connected to the first lifting mechanism lead screw 812, and a first lifting mechanism drive motor 814 drivenly connected to the first lifting mechanism lead screw 812; a first lifting component mounting plate 821 is connected to the first lifting mechanism lead screw nut 813, and a first lifting component 82 is connected to the first lifting component mounting plate 821; as the first lifting mechanism drive motor 814 rotates, the first lifting component mounting plate 821 and the first lifting component 82 are driven to move vertically through the first lifting mechanism lead screw 812 and the first lifting mechanism lead screw nut 813.

[0020] The second lifting mechanism 9 includes: a second lifting drive 91, and a second lifting member 92 connected to the lifting end of the second lifting drive 91; when the material loading assembly 3 rotates to the twisting station, its corresponding lifting through hole 211 is located between the second lifting member 92 and the lower pressing member 32, and the second lifting drive 91 can drive the second lifting member 92 to pass through the lifting through hole 211 and push the lower pressing member 32 from below.

[0021] Specifically, the second lifting drive component 91 is connected to the bottom of the frame 1 through the second lifting mechanism mounting plate 911; a lifting component bushing 912 is provided in the second lifting mechanism mounting plate 911, and the second lifting drive component 91 is a motor-driven lead screw module; the second lifting component 92 is connected to the moving end of the module through the second lifting component mounting plate 921, and the second lifting component 92 passes through the lifting component bushing 912.

[0022] The belt cutting mechanism 4 includes: a mesh bag feeding assembly 41, a lifting assembly 42, a transverse linear motion module 43, two oppositely arranged belt rollers 44, a guide sleeve 45, a cutting assembly 46, a rotary drive component 47, a mesh bag clamping assembly 48, and a yarn pull rod assembly 49.

[0023] The lifting assembly 42 includes: a belt cutting mechanism bracket 420 vertically mounted on the frame 1, a belt lifting linear module 421 vertically mounted on the belt cutting mechanism bracket 420, and a lifting mounting plate 422 connected to the moving end of the belt lifting linear module 421; the belt lifting linear module 421 can drive the lifting mounting plate 422 to reciprocate vertically, thereby driving the transverse linear motion module 43, the two belt rollers 44 and the cutting assembly 46 mounted on the lifting mounting plate 422 to lift synchronously.

[0024] Specifically, the traction belt lifting linear module 421 adopts an electric lead screw linear module set in the vertical direction. The moving slide of the traction belt lifting linear module 421 is fixedly connected to the lifting mounting plate 422. When the drive motor drives the lead screw to rotate in the forward or reverse direction, the moving slide drives the lifting mounting plate 422 to move back and forth in the vertical direction.

[0025] The transverse linear motion module 43 is mounted on the lifting mounting plate 422 and is a bidirectional linear motion module with two synchronously opposite moving ends. In this embodiment, the transverse linear motion module 43 adopts a bidirectional lead screw linear module. The bidirectional lead screw has two sections of threads with opposite directions of rotation. The two moving ends are respectively connected to the corresponding thread sections for transmission, so that the two moving ends synchronously approach or move away from each other under the drive of the same drive source.

[0026] The two moving ends of the transverse linear motion module 43 are respectively connected to a belt adapter plate 431. Each belt adapter plate 431 is connected to a belt pulley assembly connecting plate 432. Two belt pull rollers 44 are rotatably connected to the corresponding belt pulley assembly connecting plate 432 and are arranged opposite to each other on both sides of the guide sleeve 45 and the material loading assembly 3. When the transverse linear motion module 43 drives the two moving ends to approach each other, the two belt pull rollers 44 can clamp the guide sleeve 45 and the continuous net bag sleeved outside the guide sleeve 45 from opposite sides. When the two moving ends move away from each other, the two belt pull rollers 44 can reduce the clamping force on the guide sleeve 45 and the net bag, or withdraw from the outside of the two uprights 31.

[0027] The belt pulley assembly connecting plate 432 is spaced apart from the transverse linear motion module 43 by the belt pull adapter plate 431, so that the two belt pull rollers 44 and the transverse linear motion module 43 respectively form transverse through clearance gaps 433; the two clearance gaps 433 correspond to each other and together form a space for the cutting component 46 to move laterally, so that the first blade 461 can pass laterally under the two belt pull rollers 44 without interfering with the transverse linear motion module 43.

[0028] Each pull belt roller 44 is connected to a rotary drive component 47. The rotary drive component 47 is connected to the corresponding pull belt roller assembly connecting plate 432 and is connected to the corresponding pull belt roller 44 in a transmission connection. The rotary drive component 47 is a servo motor. The two pull belt rollers 44 rotate in opposite directions. When the two pull belt rollers 44 approach the mesh bag from opposite sides, the two pull belt rollers 44 use the friction between themselves and the mesh bag to jointly convey the mesh bag downward.

[0029] Both pull rollers 44 have inwardly concave arc-shaped rolling surfaces, which allows the pull rollers 44 to fit well with the guide sleeve 45 and the mesh bag sleeved on the outside of the two uprights 31, and to make the mesh bag receive relatively balanced rolling and conveying on both sides.

[0030] The guide sleeve 45 is positioned above the material carrier 3 located at the belt cutting station and can be fitted onto the top of the two uprights 31. The guide sleeve 45 is an integral U-shaped frame structure, including: a U-shaped frame 451 and a gathering guide portion 452 formed on the upper part of the U-shaped frame 451.

[0031] The upper parts of both sides of the U-shaped frame 451 are inclined inward to form a closing guide part 452, so that the guide sleeve 45 forms an outer contour that is narrower at the top and wider at the bottom. When the continuous tubular mesh bag is put into the upper part of the guide sleeve 45, it can gradually unfold along the smooth outer surface of the closing guide part 452 and be put into the outside of the U-shaped frame 451, reducing the possibility of the mesh bag being caught by sharp corners or steps during the insertion process.

[0032] The lower width of the guide sleeve 45 and its internal area are adapted to the top of the upright rod 31. When the guide sleeve 45 descends, the top of the upright rod 31 is inserted into the bottom of the guide sleeve 45, so that the guide sleeve 45 is fitted onto the top of the upright rod 31. After the guide sleeve 45 and the upright rod 31 are fitted together, they form a continuous mesh bag conveying path in the vertical direction, so that the mesh bag fitted outside the guide sleeve 45 can smoothly transition downward to the outside of the upright rod 31.

[0033] Two pull rollers 44 can clamp the guide sleeve 45 with the continuous mesh bag on it from opposite sides; at this time, the continuous mesh bag is located between the pull rollers 44 and the guide sleeve 45, and the two pull rollers 44 press the outside of the guide sleeve 45 with the continuous mesh bag, so that the guide sleeve 45 and the free end of the continuous mesh bag can be driven to rise and fall synchronously under the drive of the lifting component 42.

[0034] The cutting assembly 46 is connected to the lifting mounting plate 422 and includes: a first blade 461, a second blade 462, a cutting transverse drive 463, and an insulating blade holder 464; the cutting transverse drive 463 is arranged horizontally on the lifting mounting plate 422, the insulating blade holder 464 is connected to the moving end of the cutting transverse drive 463, and the first blade 461 is arranged on the insulating blade holder 464.

[0035] In one possible implementation, the cutting transverse drive 463 is a rodless cylinder-type linear slide arranged in the horizontal direction. The cutting transverse drive 463 includes: a transverse cylinder connected to the lifting mounting plate 422, and a movable slide capable of reciprocating along the transverse cylinder, an insulated blade holder 464 connected to the movable slide, and a first blade 461 connected to the insulated blade holder 464. In this embodiment, a rodless cylinder-type linear slide of model CY3RG20-300 can be used, with the rodless cylinder driving the movable slide, the insulated blade holder 464, and the first blade 461 to reciprocate in the horizontal direction.

[0036] The first blade 461 is initially located below one of the belt rollers 44; the second blade 462 is located at the bottom of the belt roller assembly connecting plate 432 corresponding to the other belt roller 44, below the belt roller 44; the first blade 461 and the second blade 462 are arranged with their cutting edges facing each other; during cutting, the cutting lateral drive 463 drives the first blade 461 to move laterally along the clearance gap 433 and move closer to the second blade 462, and the continuous mesh bag is cut through the cooperation of the first blade 461 and the second blade 462.

[0037] The lifting mounting plate 422 is also equipped with a mesh bag clamping assembly 48; the mesh bag clamping assembly 48 is located below the belt roller 44 and includes: a clamping telescopic cylinder 481 and a mesh bag pressing member 482 connected to the telescopic end of the clamping telescopic cylinder 481; when the clamping telescopic cylinder 481 extends, the mesh bag pressing member 482 can approach the material loading assembly 3 located at the belt cutting station and press the mesh bag sleeved on the outside of the two uprights 31 and close to the cutting position onto the material loading assembly 3; when the clamping telescopic cylinder 481 retracts, the mesh bag pressing member 482 releases the pressing of the mesh bag.

[0038] A yarn belt lever assembly 49 is also provided at the tape cutting station; the yarn belt lever assembly 49 includes: a lever mounting plate 490 connected to the lower base plate 24, a lever drive 492 connected to the lever mounting plate 490, and a yarn belt lever 491 connected to the lever drive 492; the lever drive 492 can drive the yarn belt lever 491 to rotate between the two uprights 31, pressing down the mesh bags stacked outside the two uprights 31 from above the mesh bag segment, so that the cut mesh bag segment is further concentrated downward; after pressing, the lever drive 492 drives the yarn belt lever 491 to reverse and reset, exiting the rotation path of the material loading assembly 3.

[0039] In this embodiment, the lever drive 492 adopts an existing pneumatic rotary table. The fixed end of the pneumatic rotary table is connected to the lever mounting plate 490, and its rotation output end is connected to the yarn lever 491. By rotating the rotation output end back and forth between two angular positions, the yarn lever 491 is driven to switch between the pressing position and the avoidance position.

[0040] The mesh bag feeding assembly 41 includes: a feeding wheel 411, a first transition wheel 412, a follower wheel 413, and a second transition wheel 414; the continuous cylindrical mesh bag is drawn out from the upstream material roll or storage position, guided by each wheel body, and then conveyed to the guide sleeve 45, and guided by the gathering guide part 452 and then sleeved on the outside of the guide sleeve 45.

[0041] Before the tape cutting process, the free end of the continuous cylindrical mesh bag is pre-fitted onto the outside of the guide sleeve 45. The transverse linear motion module 43 drives the two tape rollers 44 to move inward synchronously, so that the two tape rollers 44 clamp the guide sleeve 45 with the mesh bag on both sides. The guide sleeve 45 and the free end of the mesh bag are thus kept in the waiting position above the tape cutting station.

[0042] After the empty material loading assembly 3 rotates with the turntable 21 to the belt cutting station, the lifting assembly 42 drives the lifting mounting plate 422 to move downward. The two belt rollers 44 clamp the guide sleeve 45 and the mesh bag outside the guide sleeve 45 and descend synchronously, so that the guide sleeve 45 is fitted on the top of the two uprights 31.

[0043] After the guide sleeve 45 is in place, the lateral linear motion module 43 drives the two pull belt rollers 44 to move outward a small distance synchronously to reduce the clamping force of the two pull belt rollers 44 on the guide sleeve 45, while keeping the two pull belt rollers 44 in contact with the net bag. Subsequently, the two rotary drive components 47 drive the corresponding pull belt rollers 44 to rotate, conveying the net bag outside the guide sleeve 45 downward along the guide sleeve 45, so that the net bag passes the connection position between the guide sleeve 45 and the two uprights 31 and is gradually fitted onto the outside of the two uprights 31.

[0044] After the free end of the net bag is transferred to the outside of the two uprights 31, the lifting assembly 42 continues to adjust the height of the two pull rollers 44 so that the two pull rollers 44 reach the pull position outside the two uprights 31; the two pull rollers 44 continue to rotate, conveying the continuous net bags downward along the extension direction of the uprights 31; as subsequent net bags are continuously fed in, the net bags are gradually compressed and stacked along the axial direction of the two uprights 31, thereby forming the net bag stacking section required to make the bath flower ball.

[0045] Once the mesh bag reaches the predetermined conveying length, the two pull belt rollers 44 stop rotating, and the lateral linear motion module 43 drives the two pull belt rollers 44 to move outward synchronously. Subsequently, the lifting assembly 42 drives the lifting mounting plate 422 to move upward, so that the two pull belt rollers 44 move back to the outside of the guide sleeve 45. The lateral linear motion module 43 then drives the two pull belt rollers 44 to move inward synchronously again, so that the two pull belt rollers 44 re-clamp the guide sleeve 45 and the continuous mesh bag outside it.

[0046] The lifting assembly 42 continues to drive the lifting mounting plate 422 to rise, causing the two pull rollers 44 to drive the continuous net bag and guide sleeve 45 to rise synchronously. As a result, the guide sleeve 45 gradually separates from the top of the two uprights 31, and a cutting space is formed between the bottom of the guide sleeve 45 and the top of the uprights 31.

[0047] After the guide sleeve 45 disengages from the upright rod 31, the clamping telescopic cylinder 481 drives the net bag holding member 482 to approach the two upright rods 31 and hold the net bag on the outside of the upright rods 31 near the cutting position; then, the cutting transverse drive member 463 drives the insulating knife holder 464 and the first blade 461 to move horizontally. The first blade 461 passes laterally through the cutting space between the guide sleeve 45 and the upright rod 31 along the clearance gap 433 and moves toward the second blade 462.

[0048] The first blade 461 and the second blade 462 cooperate to cut the continuous net bag located between the guide sleeve 45 and the two uprights 31. After the cutting is completed, the stacked section of the net bag located outside the two uprights 31 is separated from the upstream continuous net bag, while the new free end formed after the upstream continuous net bag is cut is still sleeved outside the guide sleeve 45 and continues to be held by the two pull rollers 44.

[0049] The cutting transverse drive 463 then drives the first blade 461 out of the cutting area and resets, and the mesh bag clamping assembly 48 releases its pressure on the mesh bag segment; the lever drive 492 drives the yarn lever 491 to rotate in the area between the two uprights 31, pressing the stacked mesh bag segment from above downwards, so that the loose mesh bags located on the upper part of the uprights 31 after cutting are concentrated downwards; after the yarn lever 491 completes the pressing, it resets in the opposite direction, and the material loading assembly 3 can then carry the formed mesh bag segment to the subsequent threading and binding station with the turntable 21; the guide sleeve 45 and the new free end of the upstream continuous mesh bag remain above the pull belt cutting station, waiting for the next empty material loading assembly 3 to enter for the next pull belt cutting cycle.

[0050] The rope welding mechanism 5 is connected to the frame 1 via a welding mechanism bracket. The welding mechanism bracket includes: a first welding mechanism bracket plate 501 disposed above the frame 1, a second welding mechanism bracket plate 502 connected above the first welding mechanism bracket plate 501, and a plurality of welding mechanism support rods 503 for connecting the first welding mechanism bracket plate 501 and the second welding mechanism bracket plate 502.

[0051] The rope welding mechanism 5 includes: a moving component 51, a rope clamping jaw 52, ​​a first rotating jaw 53, a second rotating jaw 54, a shearing component 55, a welding fixture 56, an ultrasonic welding head 57, and a material dropping hole 58.

[0052] The moving component 51 includes: a welding moving linear module 511 and a welding guide slide rail assembly 512 arranged side by side on the first welding mechanism support plate 501, and a moving mounting plate 513 connected to the welding moving linear module 511 and the welding guide slide rail assembly 512; the welding moving linear module 511 extends along the arrangement direction of the shearing component 55 and the first rotating jaw 53, and is used to drive the moving mounting plate 513 to reciprocate between the shearing component 55 and the first rotating jaw 53; the welding guide slide rail assembly 512 is used to guide and provide auxiliary support for the moving mounting plate 513.

[0053] In one possible implementation, the welding moving linear module 511 is an electric lead screw linear module, which includes a drive motor, a lead screw extending along the moving direction of the moving component 51, and a moving slide connected to the lead screw. The moving mounting plate 513 is connected to the moving slide. When the drive motor rotates in the forward or reverse direction, it drives the moving mounting plate 513 to reciprocate along the welding guide slide rail assembly 512 through the lead screw. Thus, the moving stroke and stop position of the moving mounting plate 513 can be set as needed to meet the requirements of pulling ropes of different lengths and switching positions between different workstations.

[0054] A pull rope lateral movement assembly 521 is provided on the movable mounting plate 513. The pull rope lateral movement assembly 521 includes: a pull rope lateral movement telescopic cylinder 5211 connected to the movable mounting plate 513 and a first mounting plate 5212 connected to the pull rope lateral movement telescopic cylinder 5211. The pull rope gripper 52 is provided on the first mounting plate 5212. The extension and retraction direction of the pull rope lateral movement telescopic cylinder 5211 intersects with the movement direction of the movable assembly 51. Therefore, the pull rope gripper 52 can move a long distance between the shearing assembly 55 and the first rotating gripper 53 with the movable mounting plate 513, and can also be adjusted laterally by the pull rope lateral movement telescopic cylinder 5211.

[0055] The second rotating gripper 54 is mounted on the movable mounting plate 513 via the second gripper lateral moving assembly 541; the moving direction of the second gripper lateral moving assembly 541 intersects with the moving direction of the moving assembly 51, so that the second rotating gripper 54 can move closer to or further away from the continuous rope in a lateral direction.

[0056] The first rotating gripper 53 is mounted on the first welding mechanism support plate 501 via the first gripper lateral movement assembly 531. The first gripper lateral movement assembly 531 is connected to the first rotating gripper 53 via the gripper adapter plate 532 and can drive the first rotating gripper 53 to move laterally closer to or further away from the continuous rope and the welding station. The rope clamp 52 adopts a parallel opening and closing pneumatic clamp. The two clamping parts are driven to move closer or further apart by the clamping cylinder to clamp or release the continuous rope. The first rotating clamp 53 and the second rotating clamp 54 adopt a rotating pneumatic clamp with clamping and rotating functions. The clamping part is used to clamp the corresponding rope end, and the rotating part is used to drive the clamping part and the clamped rope end to rotate to change the spatial orientation of the rope end.

[0057] The first gripper lateral movement assembly 531 and the second gripper lateral movement assembly 541 are equipped with a slide cylinder. The cylinder body of the first gripper lateral movement assembly 531 is fixed on the first welding mechanism support plate 501, and its moving slide is connected to the first rotating gripper 53 through the gripper adapter plate 532. The cylinder body of the second gripper lateral movement assembly 541 is fixed on the movable mounting plate 513, and its moving slide is connected to the second rotating gripper 54. When the corresponding slide cylinder extends or retracts, it drives the first rotating gripper 53 and the second rotating gripper 54 to move laterally between the rope clamping position and the avoidance position, respectively.

[0058] The shearing assembly 55 includes: a slide base plate 551, a silicone hose 552, a slide fixing plate 553, a shearing lifting drive 554, and a pneumatic shear 555; the silicone hose 552 forms a conveying channel for the continuous rope to pass through, the continuous rope passes through the inside of the silicone hose 552 and extends out from its rope output end; the silicone hose 552 can provide certain guidance and constraint for the flexible rope so that the output position of the rope remains relatively stable.

[0059] The pneumatic shears 555 are located on the rope output end of the silicone hose 552 and are connected to the slide table fixing plate 553 via the shearing lifting drive 554. When the rope needs to be cut, the shearing lifting drive 554 drives the pneumatic shears 555 to move to the cutting position corresponding to the rope. After the cutting is completed, the pneumatic shears 555 can be withdrawn from the corresponding area to provide clearance for the subsequent movement of the rope and the gripper.

[0060] The shearing lifting drive 554 adopts a slide cylinder arranged in the vertical direction. The cylinder body of the slide cylinder is connected to the slide fixed plate 553, and its moving slide is connected to the pneumatic scissors 555. When the moving slide extends, it drives the pneumatic scissors 555 into the shearing position. When the moving slide retracts, it drives the pneumatic scissors 555 out of the shearing position.

[0061] The welding fixture 56 includes: a welding support 561, a lifting block 562, a pusher plate 563, a lifting drive 564, a pusher drive 565, a welding support plate 566, two adjusting blocks 567, and a welding transverse drive 568. The welding transverse drive 568 is connected to the first mounting plate 5212, and the welding support plate 566 is connected to the moving end of the welding transverse drive 568. The welding transverse drive 568 can drive the welding support plate 566 and other components set on the welding support plate 566 to enter or exit the welding station formed between the first rotating jaw 53 and the second rotating jaw 54.

[0062] Two adjusting blocks 567 are spaced apart on the welding support plate 566, and a lifting block 562 is raised and lowered between the two adjusting blocks 567. The upper part of the lifting block 562 forms a welding support part 561 for supporting the two ends of the rope to be welded. In the welding state, the lifting block 562 is in the lowered position, and the welding support part 561 is lower than the upper surface of the two adjusting blocks 567, so that the lifting block 562 and the two adjusting blocks 567 on both sides together form a groove-shaped welding area. The first rotating jaw 53 and the second rotating jaw 54 can respectively transfer the two ends of the rope to be welded into the groove-shaped welding area and make the two ends of the rope to be welded overlap on the welding support part 561.

[0063] After the two ends of the rope to be welded are positioned, the ultrasonic welding head 57 moves downward and presses the two ends of the rope to be welded onto the welding support part 561 of the lifting block 562. The two ends of the rope to be welded are connected into one piece by ultrasonic welding, thereby forming a closed loop rope.

[0064] The lifting end of the lifting drive component 564 is connected to the lifting block 562; after the welding is completed and the ultrasonic welding head 57 is reset upward, the lifting drive component 564 drives the lifting block 562 to move upward, so that the upper surface of the lifting block 562 rises to be basically flush with the upper surface of the two adjusting blocks 567, thereby pushing the closed loop rope upward from the grooved welding area; at this time, the upper surface of the lifting block 562 and the upper surface of the two adjusting blocks 567 together form a pushing support surface for the movement of the closed loop rope.

[0065] The pusher drive 565 is connected to the welding support plate 566, and the telescopic end of the pusher drive 565 is connected to the pusher plate 563. When the lifting block 562 rises to the position, the pusher drive 565 drives the pusher plate 563 to move along the upper surface of the lifting block 562 and the two adjusting blocks 567, thereby pushing the closed loop rope out from the welding fixture 56 and causing the closed loop rope to be output downward through the drop hole 58.

[0066] In one possible implementation, the lifting drive 564 is a vertically arranged telescopic cylinder, with its cylinder body located below the welding support plate 566. The end of its piston rod is connected to the lifting block 562 to drive the lifting block 562 to reciprocate between the descending welding position and the ascending pushing position. The pushing drive 565 is a telescopic cylinder arranged horizontally along the pushing direction, with its piston rod end connected to the pushing plate 563 to drive the pushing plate 563 to reciprocate along the upper surface of the lifting block 562 and the two adjusting blocks 567. The welding transverse drive 568 is a horizontally arranged slide cylinder, with its fixed end connected to the first mounting plate 5212 and its moving end connected to the welding support plate 566 to drive the welding fixture 56 as a whole into or out of the welding position between the first rotating jaw 53 and the second rotating jaw 54.

[0067] The ultrasonic welding head 57 is located above the welding fixture 56. Specifically, a welding mounting bracket 571 is provided on the second welding mechanism support plate 502. Two guide shafts 572 are provided on the welding mounting bracket 571 in the vertical direction. The bottom of the two guide shafts 572 passes through the second welding mechanism support plate 502 and is connected to the welding mounting plate 573. The ultrasonic welding head 57 is set on the welding mounting plate 573. The two guide shafts 572 are used to limit the vertical movement direction of the welding mounting plate 573 and the ultrasonic welding head 57 to reduce the lateral displacement generated during the lifting and lowering of the ultrasonic welding head 57.

[0068] A welding lifting drive component 574 is connected between the second welding mechanism support plate 502 and the welding mounting bracket 571. The welding lifting drive component 574 cooperates with the lifting structure formed by the welding mounting bracket 571, the guide shaft 572 and the welding mounting plate 573, so that the welding mounting plate 573 and the ultrasonic welding head 57 can be raised and lowered in the vertical direction. During welding, the ultrasonic welding head 57 moves downward to the position of the welding fixture 56 and presses and ultrasonically welds the two ends of the rope to be welded. After welding is completed, the ultrasonic welding head 57 returns to its original position, providing clearance for the subsequent actions of the rotating gripper and the welding fixture 56.

[0069] The welding lifting drive component 574 adopts a vertically arranged telescopic cylinder, the fixed end of which is connected to the second welding mechanism support plate 502, and the piston rod end is connected to the welding mounting bracket 571. The welding mounting bracket 571 is connected to the welding mounting plate 573 through the guide shaft 572, so that the telescopic cylinder maintains vertical guidance when driving the welding mounting plate 573 and the ultrasonic welding head 57 to rise and fall.

[0070] When the rope welding mechanism 5 is working, the continuous rope first extends from the rope output end of the silicone hose 552; in the initial state, the moving component 51 is located on the side of the shearing component 55, and the rope lateral movement component 521 moves to bring the rope clamp 52 close to the continuous rope; after the rope clamp 52 clamps the free end of the continuous rope, the welding moving linear module 511 drives the moving mounting plate 513 to move along the welding guide slide rail component 512 to the side of the first rotating clamp 53, so that the rope clamp 52 pulls out the continuous rope of a preset length.

[0071] When the moving component 51 moves to the area where the first rotating jaw 53 is located, the pull rope jaw 52 pulls the free end of the continuous rope it is holding across the clamping position of the first rotating jaw 53. The first jaw lateral movement component 531 drives the first rotating jaw 53 to move towards the position of the rope, so that the rope enters the clamping range of the first rotating jaw 53. The first rotating jaw 53 closes and clamps the rope. At this time, the free end of the rope is still located outside the first rotating jaw 53, so that a section of rope is left between the first rotating jaw 53 and the free end of the rope for subsequent lap welding.

[0072] After the first rotating jaw 53 completes clamping, the pull rope jaw 52 releases the continuous rope, allowing the first rotating jaw 53 to take over the corresponding rope end; subsequently, the pull rope lateral movement component 521 drives the pull rope jaw 52 to retract laterally, and the moving component 51 drives the pull rope jaw 52 and the second rotating jaw 54 to return to the side where the shearing component 55 is located.

[0073] After the moving component 51 returns, the second gripper lateral movement component 541 drives the second rotating gripper 54 to approach and clamp the continuous rope, so that a rope segment for subsequent lap welding is also left between the second rotating gripper 54 and the cutting position of the cutting component 55; after the second rotating gripper 54 is in place, the cutting lifting drive component 554 drives the pneumatic shears 555 to enter the cutting position, and the pneumatic shears 555 cuts the continuous rope, thereby obtaining an independent rope segment with a preset length, one end of which is clamped by the first rotating gripper 53 and the other end of which is clamped by the second rotating gripper 54; since the two sides of the rope are constrained by the first rotating gripper 53 and the second rotating gripper 54 respectively before the rope is cut, the two rope ends are not in a completely free state.

[0074] After the cutting is completed, the moving component 51 moves again to the side where the first rotating jaw 53 is located. The second rotating jaw 54, along with the moving component 51, moves the second rope end it holds closer to the first rope end held by the first rotating jaw 53, so that the flexible rope segment between the two rope ends naturally bends to form a loop.

[0075] After the moving component 51 moves to the predetermined position, the welding transverse drive component 568 drives the welding fixture 56 to enter the welding position between the first rotating jaw 53 and the second rotating jaw 54; the first rotating jaw 53 and the second rotating jaw 54 respectively drive the two rope ends to change direction, thereby transferring the parts to be welded at the two rope ends to the groove-shaped welding area formed by the lifting block 562 and the two adjusting blocks 567, and making the two rope ends to be welded overlap on the welding support part 561.

[0076] After the two rope ends are positioned, the ultrasonic welding head 57 moves downward and presses against the two rope ends to be welded located on the welding support 561. The two rope ends are connected into one piece by ultrasonic welding, thereby forming a closed loop rope from the independent rope segments.

[0077] After welding is completed, the ultrasonic welding head 57 returns to its original position, the first rotating gripper 53 and the second rotating gripper 54 release the closed loop rope and exit backward through the corresponding transverse component; the lifting drive 564 drives the lifting block 562 to move upward, and the upper surface of the lifting block 562 is flush with the upper surface of the adjusting block 567; then, the pushing drive 565 drives the pushing plate 563 to move, pushing the closed loop rope out of the welding fixture 56, and the closed loop rope is output downward through the discharge hole 58.

[0078] In this embodiment, the loop receiving position of the threading and binding mechanism 6 is located below the material drop hole 58. Specifically, the threading assembly 60 is located below the first welding mechanism support plate 501. During the loop forming process of the loop welding mechanism 5, the threading assembly 60 can move to the bottom of the loop welding mechanism 5, so that the first threading rod 61 and the second threading rod 62 are inserted between the formed loop rope segments. After the loop rope is welded and released by the welding fixture 56, the closed loop rope can be sleeved on the first threading rod 61 and the second threading rod 62 for subsequent threading and binding.

[0079] The threading and binding mechanism 6 includes: a threading assembly 60, an upper pressing assembly 64, a winding assembly 65, a tensioning assembly 66, a threading rod lifting assembly 67, a second threading rod lifting assembly 68, and a winding lifting assembly 69.

[0080] The rope threading assembly 60 is located below the first welding mechanism support plate 501 and includes: a first rope threading rod 61, a second rope threading rod 62, a second rope threading rod transverse movement cylinder 621, a stop block 622, and a rope threading moving assembly 63; the rope threading rod lifting assembly 67 is connected to the moving end of the rope threading moving assembly 63, and the first rope threading rod 61 is connected to the lifting end of the rope threading rod lifting assembly 67; the second rope threading rod lifting assembly 68 is also located at the lifting end of the rope threading rod lifting assembly 67, the second rope threading rod transverse movement cylinder 621 and the stop block 622 are both located at the moving end of the second rope threading rod lifting assembly 68, the second rope threading rod 62 is connected to the telescopic end of the second rope threading rod transverse movement cylinder 621, and the second rope threading rod 62 can extend or retract relative to the stop block 622 along its own extension direction.

[0081] Therefore, when the rope-threading moving component 63 is activated, it can drive the rope-threading rod lifting component 67, the first rope-threading rod 61, the second rope-threading rod lifting component 68, the second rope-threading rod lateral movement cylinder 621, the stop block 622, and the second rope-threading rod 62 as a whole to move closer to or further away from the material-carrying component 3; when the rope-threading rod lifting component 67 is activated, it can drive the first rope-threading rod 61, the second rope-threading rod 62, the second rope-threading rod lateral movement cylinder 621, the stop block 622, and the second rope-threading rod lifting component 68 to rise and fall as a whole; when the second rope-threading rod lifting component 68 is activated, it can drive the second rope-threading rod lateral movement cylinder 621, the stop block 622, and the second rope-threading rod 62 to rise and fall relative to the first rope-threading rod 61; when the second rope-threading rod lateral movement cylinder 621 is activated, it can drive the second rope-threading rod 62 to extend or retract relative to the stop block 622 along its own extension direction.

[0082] In this embodiment, the rope-threading moving component 63 is an electric lead screw linear module; Specifically, the rope-threading rod lifting assembly 67 includes: a module base plate 671 connected to the moving end of the rope-threading moving assembly 63, four rope-threading guide rods 672 connected to the module base plate 671, an L-shaped rope-threading rod lifting bracket 673 slidably connected to the rope-threading guide rods 672, and a rope-threading rod lifting drive component 674 connected between the module base plate 671 and the rope-threading rod lifting bracket 673.

The second rope-threading rod lifting assembly 68 is connected to the surface of the vertical plate of the rope-threading rod lifting bracket 673. The second rope-threading rod transverse cylinder 621 and the stop block 622 are disposed at the moving end of the second rope-threading rod lifting assembly 68. The second rope-threading rod 62 is below the first rope-threading rod 61 and is connected to the telescopic end of the second rope-threading rod transverse cylinder 621. The extended end of the second rope-threading rod 62 can extend or retract relative to the stop block 622.

[0084] In this embodiment, the rope-threading rod lifting drive 674 adopts a vertically arranged telescopic cylinder. Its fixed end is connected to the module base plate 671, and its telescopic end is connected to the rope-threading rod lifting bracket 673. When the telescopic end of the rope-threading rod lifting drive 674 moves, it drives the first rope-threading rod 61, the second rope-threading rod lifting assembly 68, the second rope-threading rod transverse cylinder 621, the stop block 622, and the second rope-threading rod 62 to move as a whole.

[0085] In this embodiment, the second rope-threading rod lifting assembly 68 is a rodless cylinder. The second rope-threading rod transverse cylinder 621 and the stop block 622 are connected to its moving slide to drive the second rope-threading rod transverse cylinder 621, the stop block 622 and the second rope-threading rod 62 to rise and fall independently relative to the first rope-threading rod 61.

[0086] In this embodiment, the second rope-threading rod transverse movement cylinder 621 is arranged along the extension direction of the second rope-threading rod 62, and its telescopic end is connected to the second rope-threading rod 62; the stop block 622 is connected to the front end of the second rope-threading rod transverse movement cylinder 621, located on the movement path of the second rope-threading rod 62, and movably sleeved on the outside of the second rope-threading rod 62; when the second rope-threading rod transverse movement cylinder 621 is in the extended state, the extended end of the second rope-threading rod 62 extends outward of the stop block 622 to carry the second rope segment; when the second rope-threading rod transverse movement cylinder 621 retracts, the second rope-threading rod 62 retracts relative to the stop block 622, the stop block 622 blocks the second rope segment, causing the second rope segment to detach from the extended end of the second rope-threading rod 62.

[0087] The first rope-threading rod 61 is provided with a first limiting part 611, a second limiting part 612 and a third limiting part 613 at intervals along its extension direction. The three limiting parts respectively receive the corresponding rope segments of the closed loop rope during the binding process.

[0088] The upper pressing assembly 64, the tensioning assembly 66, and the flipping and lifting assembly 69 are disposed on the lower base plate 24; the upper top plate 26 is connected to the lower base plate 24 by equal height columns 25; the upper pressing assembly 64 includes: an upper pressing member 641 and a pressing drive member 642 connected to the upper pressing member 641; the pressing drive member 642 is used to drive the upper pressing member 641 to move between the pressing position and the avoidance position; when the upper pressing member 641 is in the pressing position, it corresponds vertically to the material loading assembly 3 located at the wire binding station; when the upper pressing member 641 is in the avoidance position, it is disengaged from the rotation path of the material loading assembly 3 and the two uprights 31, so that the material loading assembly 3 can rotate with the turntable 21.

[0089] The pressing drive 642 adopts a telescopic cylinder arranged in the vertical direction, with its fixed end set on the upper top plate 26 and its moving end connected to the upper pressing component 641.

[0090] When the material-carrying assembly 3 carrying the mesh bag segment enters the threading and binding station, the pressing drive 642 drives the upper pressing component 641 into the pressing position, and the first lifting drive 81 drives the first lifting component 82 to move upward. The first lifting component 82 passes through the corresponding lifting through hole 211 and pushes the lower pressing component 32 upward, so that the lower pressing component 32 moves upward along the two uprights 31, thereby pressing the mesh bag segment stacked outside the two uprights 31 between the lower pressing component 32 and the upper pressing component 641, so that a relatively concentrated binding area is formed in the middle of the mesh bag segment. After binding is completed, the pressing drive 642 drives the upper pressing component 641 to move upward to the avoidance position.

[0091] The flipping and lifting assembly 69 is vertically mounted on the lever mounting plate 490 on the lower base plate 24, and the flipping assembly 65 is connected to the moving end of the flipping and lifting assembly 69. The flipping and lifting assembly 69 can drive the flipping assembly 65 to rise and fall vertically, so that the flipping assembly 65 can move between the lower position where the second rope rod 62 is located and the upper position where the first rope rod 61 is located.

[0092] The flipping and lifting assembly 69 adopts an electric screw slide, the fixed end of which is installed on the lever mounting plate 490. Its movable slide is connected to the flipping assembly 65 to drive the pull hook 651, the pull hook drive assembly 652, the sleeve 653 and the sleeve drive component 654 to lift as a whole.

[0093] The winding assembly 65 includes: a hook 651, a hook drive assembly 652, a sleeve 653, and a sleeve drive component 654; the hook drive assembly 652 is connected to the moving end of the winding lifting assembly 69, the hook 651 is connected to the moving end of the hook drive assembly 652, the sleeve drive component 654 is connected below the hook 651, and the sleeve 653 is connected to the telescopic end of the sleeve drive component 654; the hook drive assembly 652 is arranged laterally and is used to drive the hook 651, the sleeve drive component 654, and the sleeve 653 to move relative to the rope threading assembly 60, so that the hook 651, the sleeve drive component 654, and the sleeve 653 move as a whole relative to the rope threading assembly 60, causing the hook 651, the sleeve drive component 653, and the sleeve 653 to move. The tube drive 654 and the sleeve 653 as a whole can approach or move away from the first rope rod 61 and the second rope rod 62; the sleeve 653 moves relative to the hook opening of the hook 651 under the drive of the sleeve drive 654; in this embodiment, the hook opening of the hook 651 is at the front end of the hook 651 and is a downwardly arranged semi-circular groove; when the sleeve 653 avoids the hook opening of the hook 651, the looped rope can enter or leave the hook 651; when the sleeve 653 moves to the hook opening position, it can form a closure on the hook opening of the hook 651 to restrict the hooked rope segment from detaching from the hook 651.

[0094] The hook drive assembly 652 uses an electric screw module arranged along the direction of the hook 651 near or away from the rope threading assembly 60, with the hook 651 connected to its moving end; the flipping and lifting assembly 69 provides vertical movement, and the hook drive assembly 652 provides lateral movement. The two movements cooperate to enable the hook 651 to complete the hooking action; the sleeve drive component 654 uses a small-stroke telescopic cylinder that moves in the same direction as the sleeve 653. Its telescopic end is connected to the sleeve 653 to drive the sleeve 653 to reciprocate between the open position where the hook opening of the hook 651 is exposed and the closed position where the hook opening of the hook 651 is closed.

[0095] The tensioning assembly 66 includes a tensioning gripper 661 located above the first rope threading rod 61, and a tensioning drive member 662 connected to the tensioning gripper 661. The tensioning gripper 661 can clamp the looped rope according to the binding action, and the tensioning drive member 662 can drive the tensioning gripper 661 to rise and fall, so as to cooperate with the rope threading moving assembly 63 to drive the overall lateral movement of the first rope threading rod 61 and the second rope threading rod 62 to complete the looping and final tightening.

[0096] The tensioning drive 662 is a cylinder arranged in a vertical direction. Its moving end is connected to the tensioning gripper 661 to drive the tensioning gripper 661 to move up and down between the rope-taking position near the first rope-threading rod 61 and the tensioning position away from the first rope-threading rod 61. The tensioning gripper 661 is a parallel opening and closing pneumatic gripper, which has its own clamping cylinder for controlling the opening and closing of the two clamping parts to complete the clamping and releasing of the looped rope. The tensioning drive 662 is used to drive the entire tensioning gripper 661 to move up and down.

[0097] After the loop rope is fitted onto the first rope-threading rod 61, the portion of the closed loop rope located on the side of the first rope-threading rod 61 and limited by the first limiting part 611 is called the first rope segment, and the portion of the closed loop rope that mates with the second rope-threading rod 62 is called the second rope segment; the first rope segment and the second rope segment are different parts of the same closed loop rope.

[0098] After the loop rope is received by the first limiting part 611, the second rope-threading rod lifting assembly 68 drives the second rope-threading rod lateral movement cylinder 621, the stop block 622 and the second rope-threading rod 62 in the extended state to move downward relative to the first rope-threading rod 61. The second rope-threading rod 62 drives the second rope segment downward, so that the closed loop rope is stretched and unfolded in the vertical direction between the first rope-threading rod 61 and the second rope-threading rod 62. At this time, the first rope segment is limited by the first limiting part 611 of the first rope-threading rod 61, and the second rope segment is supported by the second rope-threading rod 62.

[0099] The rope-threading moving component 63 then drives the first rope-threading rod 61 and the second rope-threading rod 62 to move toward the material-carrying component 3 located at the rope-threading and binding station. The upper pressing component 641 and the lower pressing component 32 are respectively provided with rope-threading clearance parts 321 corresponding to the area of ​​the net bag to be bound. The first rope-threading rod 61 and the second rope-threading rod 62 pass through the rope-threading clearance parts 321 of the upper pressing component 641 and the lower pressing component 32, respectively, and pass through the upper and lower sides of the pressed net bag segment. The first rope-threading rod 61 carries the first rope segment through the upper side of the pressed net bag segment, and the second rope-threading rod 62 carries the second rope segment through the lower side of the pressed net bag segment, so that the closed loop rope is located on the upper and lower sides of the net bag segment respectively.

[0100] Subsequently, the flipping and lifting assembly 69 drives the flipping assembly 65 to move downwards as a whole, so that the hook 651 is above the second rope rod 62; the sleeve drive 654 causes the sleeve 653 to avoid the hook opening of the hook 651, and the hook drive assembly 652 drives the hook 651 to extend towards the second rope rod 62, so that the hook opening of the hook 651 moves to the rope connection position on the second rope rod 62 and corresponding to the second rope segment.

[0101] After the hook 651 extends to its position, the second rope-threading rod lateral movement cylinder 621 drives the second rope-threading rod 62 to retract along its own extension direction. During the retraction of the second rope-threading rod 62, the second rope segment is blocked by the stop block 622, and the second rope-threading rod 62 continues to retract until the second rope segment disengages from the end of the second rope-threading rod 62 and springs upward into the hook opening of the hook 651 under its own tension. After the hook 651 hooks the second rope segment, the sleeve drive component 654 drives the sleeve 653 to move to the hook opening of the hook 651, thereby restricting the second rope segment from detaching. Subsequently, the second rope-threading rod lifting assembly 68 drives the second rope-threading rod lateral movement cylinder 621 to retract along its own extension direction. 21. The stop block 622 and the second rope rod 62 in the retracted state move upward and retract; the hook drive assembly 652 drives the hook 651 and the sleeve 653 to retract synchronously, and the turning lifting assembly 69 then drives the turning assembly 65 to move upward as a whole. The hook 651 carries the second rope segment from the height of the second rope rod 62 to above the first rope rod 61; when it moves above the first rope rod 61, the hook drive assembly 652 drives the hook 651 and the sleeve 653 to extend synchronously, so that the second rope segment passes around the first rope segment located at the first limiting part 611 and transfers the second rope segment to the position of the second limiting part 612.

[0102] The sleeve drive component 654 drives the sleeve 653 to retract and avoid the hook opening of the hook 651, causing the second rope segment to fall downward into the second limiting part 612. The hook drive component 652 drives the hook 651 and the sleeve 653 to exit.

[0103] Next, the tensioning drive 662 drives the tensioning gripper 661 to move downwards, and the tensioning gripper 661 clamps the first rope segment located at the first limiting part 611 and keeps it stationary; the rope threading rod lifting assembly 67 drives the first rope threading rod 61 and the second rope threading rod lifting assembly 68 to move downwards as a whole; with the tensioning gripper 661 restricting the position of the first rope segment, the rope threading moving assembly 63 continues to drive the first rope threading rod 61 and the second rope threading rod 62 to move forward as a whole; since the first rope segment is restricted by the tensioning gripper 661, and the first rope threading rod 61 continues to move forward, the first rope segment passes around the second rope segment located at the second limiting part 612 and moves to the position corresponding to the third limiting part 613; subsequently, the tensioning gripper 661 releases the first rope segment, so that the first rope segment enters the third limiting part 613.

[0104] After the first rope segment enters the third limiting part 613, the rope-threading moving component 63 drives the first rope-threading rod 61 and the second rope-threading rod 62 to move backward as a whole, so that the second rope segment located in the second limiting part 612 moves to the tensioning claw 661, and the tensioning claw 661 clamps the second rope segment in the second limiting part 612.

[0105] Subsequently, the tensioning drive 662 drives the tensioning claw 661 to pull the second rope segment upward. At the same time, the rope threading moving component 63 continues to drive the first rope threading rod 61 and the second rope threading rod 62 to move backward as a whole, so that the first rope threading rod 61 gradually exits the closed loop rope. As the tensioning claw 661 continues to pull the second rope segment upward, the cross-wrap that has been formed between the first rope segment and the second rope segment gradually tightens and forms a knot in the middle of the net bag segment, thereby completing the binding of the closed loop rope to the net bag segment.

[0106] After binding is completed, the clamping claw 661 releases the second rope segment and resets, the hook 651 and the winding assembly 65 reset, the second rope threading rod transverse movement cylinder 621 drives the second rope threading rod 62 to extend and reset, the rope threading moving assembly 63 drives the first rope threading rod 61 and the second rope threading rod 62 to exit the rotation path of the material loading assembly 3; the first lifting drive 81 drives the first lifting member 82 to descend, and the lower pressing member 32 descends along the two uprights 31; the pressing drive 642 drives the upper pressing member 641 to move to the avoidance position; after each execution component exits, the material loading assembly 3 can continue to rotate with the turntable 21 to the twisting station.

[0107] The twisting mechanism 7 includes a left twisting component 71 and a right twisting component 72, which are spaced apart on the same side of the working area where the material carrier component 3 is located. The left twisting component 71 and the right twisting component 72 are respectively arranged corresponding to the mesh bag parts on both sides of the binding position in the middle of the material carrier component 3.

[0108] Both the left and right twill assembly 71 and the right twill assembly 72 include: a support base 73, a drive component 74, a twill mounting plate 75, a sliding component 76, a track plate 77, a follower component 78, and a twill gripper 79.

[0109] The twill mounting plate 75 is disposed on the support base 73; the sliding component 76 includes: a linear guide rail 762 connected to the twill mounting plate 75 and a slider 761 slidably connected to the linear guide rail 762; the slider 761 can reciprocate relative to the twill mounting plate 75 along the extension direction of the linear guide rail 762.

[0110] The slider 761 is provided with a slide rail 763 perpendicular to the extension direction of the linear guide rail 762. A slide rod 764 is slidably connected in the slide rail 763, so that the slide rod 764 can reciprocate relative to the slider 761 in a direction perpendicular to the linear guide rail 762. Therefore, the slide rod 764 can move along the linear guide rail 762 with the slider 761, and can also move relative to the slider 761 along the slide rail 763, thus forming two mutually perpendicular linear motion degrees of freedom.

[0111] The track plate 77 is connected to the twill mounting plate 75, and the track plate 77 has a track groove 771; one end of the slide rod 764 is connected to a follower 78, which is slidably connected in the track groove 771; the other end of the slide rod 764 is connected to a twill clamp 79; the movement of the follower 78 along the track groove 771 can be transmitted to the twill clamp 79 through the slide rod 764, so that the twill clamp 79 moves according to the track defined by the track groove 771.

[0112] In this embodiment, the track groove 771 is a continuously extending curved groove with an overall U-shape, including: a first extension segment 7711 and a second extension segment 7712 arranged at intervals, and a transition segment 7713 connecting the first extension segment 7711 and the second extension segment 7712. The ends of the first extension segment 7711 and the second extension segment 7712 away from the transition segment 7713 respectively form closed ends. The follower 78 is slidably disposed in the track groove 771 and can move along the first extension segment 7711, the transition segment 7713 and the second extension segment 7712.

[0113] The drive member 74 is connected to the knitting mounting plate 75. The output shaft of the drive member 74 passes through the knitting mounting plate 75 and the track plate 77 and is connected to one end of the transmission rod 765. The other end of the transmission rod 765 is provided with a limiting strip hole 766. The follower member 78 has a part that extends out of the track groove 771. The limiting strip hole 766 is sleeved on the part of the follower member 78 located outside the track groove 771.

[0114] In this embodiment, the driving component 74 is a servo motor, and a speed reduction mechanism can be provided between the driving component 74 and the transmission rod 765. The driving component 74 rotates in the forward or reverse direction within a predetermined angle range, causing the transmission rod 765 to drive the follower 78 to reciprocate along the track groove 771. The speed reduction mechanism can reduce the rotational speed of the transmission rod 765 and increase the output torque, so that the compound motion of the flower-picking claw 79 is more stable.

[0115] When the drive member 74 drives the transmission rod 765 to rotate, the transmission rod 765 drives the follower 78 to move through the limiting strip hole 766. Since the follower 78 is simultaneously guided and restricted by the track groove 771, the follower 78 moves according to the shape of the track groove 771. When the follower 78 moves within the first extension section 7711, the transition section 7713 and the second extension section 7712, the position of the picking claw 79 is changed by the cooperation of the slide rod 764 and the slider 761, so that the picking claw 79 can smoothly switch between the stroke of extending towards the net bag and the pull-back stroke after clamping the net bag.

[0116] When the follower 78 moves along the track groove 771, its displacement in one direction can drive the slider 761 to slide along the linear guide rail 762, and its displacement in another direction perpendicular to the above direction can drive the slide rod 764 to slide relative to the slider 761 along the slide rail 763, thereby converting the rotational motion output by the drive member 74 into a compound linear motion of the slider 761 and the slide rod 764 in mutually perpendicular directions.

[0117] Since the claw 79 is connected to the end of the slide bar 764 away from the follower 78, the slider 761, slide bar 764, follower 78, track groove 771 and transmission rod 765 cooperate with each other to drive the claw 79 to move along a preset composite motion trajectory.

[0118] The pneumatic gripper 79 is a parallel opening and closing type. When the pneumatic gripper 79 moves to the position of the net bag, it grips part of the net bag. After pulling back, the pneumatic gripper 79 releases the net bag, thus cooperating with the composite motion trajectory formed by the drive component 74 to complete the approach, gripping, pulling back and releasing actions.

[0119] After the tied net bag segment rotates to the twisting station with the material carrier 3, the left twisting component 71 and the right twisting component 72 are both located on the same side of the material carrier 3 and correspond to the net bag parts on both sides of the middle binding position. The drive components 74 of the left twisting component 71 and the right twisting component 72 drive the corresponding transmission rods 765 to rotate. The transmission rods 765 drive the follower 78 to move along the corresponding track groove 771, and drive the twisting claw 79 to move according to the preset trajectory through the slider 761 and the slide rod 764. This causes the twisting claw 79 to move from the side of the material carrier 3 close to the twisting mechanism 7, across the top of the material carrier 3, and towards the side of the material carrier 3 away from the twisting mechanism 7, so as to approach the net bag part to be clamped.

[0120] After the pinching claw 79 moves to the clamping position, it clamps the net bag. The pinching claw 79 clamps the part of the net bag located on the side of the material loading assembly 3 away from the pinching mechanism 7. As the transmission rod 765 continues to move, the follower 78, guided by the track groove 771, drives the pinching claw 79 into the pull-back stroke, moving from the top of the material loading assembly 3 towards the pinching mechanism 7, thereby pulling the clamped part of the net bag towards the side where the pinching mechanism 7 is located. After the pinching claw 79 completes one pull, it releases the net bag. The drive component 74 reverses the drive and moves again to the clamping position according to the preset trajectory.

[0121] The left and right flower-pinching components 71 and 72 repeat the clamping, pulling and releasing actions on the net bags on both sides of the central binding position, so that the net bags that were originally tied and stacked outside the two uprights 31 gradually loosen and unfold around the central binding position, thus forming a fluffy bath flower ball.

[0122] After the flower-pulling process is completed, the flower-pulling claws 79 of the left flower-pulling component 71 and the right flower-pulling component 72 retract from the area above the flower ball and the material-carrying component 3 and reset, so as to provide clearance for the upward push of the flower ball.

[0123] Simultaneously with the twisting action, the second lifting drive 91 drives the second lifting member 92 to move upward, so that the second lifting member 92 passes through the lifting through hole 211 corresponding to the current material loading component 3, and pushes the lower pressing member 32 from below; the lower pressing member 32 continues to move upward along the two uprights 31, so that the tied net bag gradually moves upward, so as to facilitate the twisting action of the left twisting component 71 and the right twisting component 72; after the twisting is completed, the bath flower ball continues to be lifted upward until the bath flower ball passes over the top of the two uprights 31 and detaches from the material loading component 3, completing the unloading of the bath flower ball.

[0124] Because the left twisting assembly 71 and the right twisting assembly 72 twist from the opposite side toward the side closer to the twisting mechanism 7, the entire flower ball fluffs up toward the twisting mechanism 7 and falls toward the twisting mechanism 7 after detaching from the upright bar 31. In one embodiment, a drop plate 70 is provided between the left twisting assembly 71 and the right twisting assembly 72. After detaching from the upright bar 31, the flower ball rolls down from the drop plate 70.

[0125] After the bath ball detaches, the second lifting drive 91 drives the second lifting component 92 to descend, and the lower pressing component 32 descends and resets along the two uprights 31; the empty material loading component 3 then continues to rotate with the turntable 21 and re-enters the belt cutting station.

[0126] When the equipment is running continuously, multiple material-carrying components 3 can be in different processing positions. The material-carrying component 3 located at the belt cutting position completes the rolling down, compression stacking and cutting of continuous net bags. The rope welding mechanism 5 can simultaneously prepare closed-loop ropes. The material-carrying component 3 located at the threading and binding position completes the pressing of net bag segments, rope unfolding, threading, turning and tightening binding. The material-carrying component 3 located at the flower-pulling position completes the repeated clamping and pulling of the bound net bag segments, unfolding and shaping, and the ejection and unloading of the flower balls.

[0127] After each station completes its current processing action and the corresponding moving parts exit the rotation path of the material carrier 3, the hollow rotary table 22 drives the turntable 21 to perform one indexing rotation, so that the material carrier 3 that has completed the tape cutting enters the threading and binding station, the material carrier 3 that has completed the threading and binding enters the flower-pinching station, and the material carrier 3 that has completed the bath ball unloading re-enters the tape cutting station. This cycle continues, thereby continuously completing the automated production of bath balls.
