DETAILED DESCRIPTION

[0043] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0044] As shown in Figures 1 to 13 , a woven bag packing machine of the present application comprises a rack 1, the rack 1 is provided with a packing table 11, the upper side of the packing table 11 is provided with an extrusion plate 12 and a driving member 13 for driving the extrusion plate 12 to move up and down reciprocally, the driving member 13 can be provided as a hydraulic cylinder. The opposite sides of the packing table 11 and the extrusion plate 12 are each provided with a plurality of rope slots 100 for the rope 14 to pass through, the plurality of rope slots 100 on the packing table 11 and the plurality of rope slots 100 on the extrusion plate 12 are provided one by one in correspondence, the plurality of rope slots 100 are provided in intervals along the length direction of the rack 1, each of the plurality of rope slots 100 is provided along the width direction of the rack 1, and both ends are open.

[0045] In this embodiment, for the convenience of understanding, the length direction of the rack 1 is defined as the left-right direction, and the width direction of the rack 1 is defined as the front-rear direction.

[0046] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , specifically, in use, the rope 14 for bundling the woven bags is placed in the rope slot 100 on the packing table 11, then a layer of packing layer is laid on the packing table 11, and a pile of woven bags of a certain number is placed on the packing layer, finally a layer of packing layer is also laid on the top of the woven bags, then the driving member 13 is started to drive the extrusion plate 12 to move downward, the woven bags on the packing table 11 are extruded, after extrusion, one end of the rope 14 is passed through the rope slot 100 on the extrusion plate 12 and connected and tied with the other end of the rope 14, and the packing of the woven bags is completed.

[0047] Referring to Figure 4 , Figure 5 , Figure 6 , Figure 7The frame 1 is further provided with a plurality of rope guiding mechanisms corresponding to the plurality of rope setting grooves 100. Each rope guiding mechanism comprises a rope setting frame 21, a sliding block 22 slidingly arranged in the rope setting groove 100, and a driving assembly for driving the sliding block 22 to move along the length direction of the rope setting groove 100. The rope setting frame 21 is mounted on the packing table 11, the sliding block 22 is mounted on the extrusion plate 12, the rope setting frame 21 is arranged at one end of the rope setting groove 100, and the lower end of the sliding block 22 is provided with a rope hooking rod 221. One end of the rope 14 is a traction end, and the other end is a free end, and the free end can be introduced and passed through the traction end. The driving assembly comprises a moving block 23, a screw rod 24, a screw rod driving mechanism, a self-locking structure and a reset structure. The screw rod 24 is rotationally arranged in the rope setting groove 100 on the extrusion plate 12, and the screw rod 24 is arranged along the length direction of the rope setting groove 100. The moving block 23 is threadedly connected with the screw rod 24, and the sliding block 22 is axially slidably connected with the screw rod 24. The screw rod driving mechanism is used for driving the screw rod 24 to rotate. The self-locking structure is used for connecting the moving block 23 and the sliding block 22. When the two are connected, the sliding block 22 can move synchronously with the moving block 23. When the connection between the two is disconnected, the sliding block 22 can move relative to the moving block 23. The reset structure is used for driving the sliding block 22 to move along the axial direction of the screw rod 24 after the connection between the sliding block 22 and the moving block 23 is disconnected.

[0048] Referring to Figure 8 , Figure 9 , Figure 10 , Figure 11, specifically, first, the rope 14 for bundling the woven bags is placed in the rope placing groove 100 on the packing table 11, and the pulling end of the rope 14 is hung on the rope placing frame 21, then the lower packing layer, the woven bag and the upper packing layer are placed on the packing table 11 in turn, and then the driving member 13 is started to drive the pressing plate 12 to move downward to press the woven bags on the packing table 11. In the process of downward movement of the pressing plate 12, the screw rod 24 can be driven to rotate by the screw rod driving mechanism, so that the moving block 23 threadedly matched with the screw rod 24 moves along the axial direction of the screw rod 24, and the moving block 23 can move from the front end of the rack 1 to the rear end of the rack 1. In this process, the sliding block 22 is connected with the moving block 23 under the action of the self-locking structure, so that the sliding block 22 can move synchronously with the moving block 23 until the sliding block 22 and the moving block 23 move to the rear end of the rack 1. After the woven bags are pressed, the pressing plate 12 stops moving downward, and the connection between the sliding block 22 and the moving block 23 is disconnected at this time, so that the sliding block 22 can move along the axial direction of the screw rod 24 under the action of the reset structure, and the sliding block 22 moves from the rear end of the rack 1 to the front end of the rack 1. Since the height of the rope hooking rod 221 at the lower end of the sliding block 22 corresponds to the height of the pulling end of the rope 14 on the rope placing frame 21 when the pressing plate 12 stops moving downward, the rope hooking rod 221 at the lower end of the sliding block 22 can be inserted into the pulling end of the rope 14 during the movement of the sliding block 22 along the axial direction of the screw rod 24, and the pulling end of the rope 14 can move synchronously with the movement of the sliding block 22, so that the pulling end of the rope 14 can pass through the rope placing groove 100 on the pressing plate 12 and move to the front end of the rack 1. At this time, the worker can introduce the free end of the rope 14 through the pulling end of the rope 14 to bundle the pressed woven bags, without manually threading the rope into the rope placing groove 100 on the pressing plate 12, saving time and effort and improving the packing efficiency.

[0049] Referring to Figure 12 In some embodiments, the lower end of the sliding block 22 is fixedly provided with a mounting rod 222, one end of the rope hooking rod 221 is rotationally connected with the lower end of the mounting rod 222 through a torsion spring, and the other end of the rope hooking rod 221 gradually inclines upward away from the mounting rod 222.

[0050] Specifically, as Figure 1 , Figure 6 , Figure 7 , Figure 12As shown, in the normal state, the hooking rod 221 is kept in an upwardly inclined state by the force of the torsion spring I, so that the traction end of the rope 14 will be at the connection between the hooking rod 221 and the mounting rod 222 during the movement of the slider 22 and the traction end of the rope 14, and will not fall off during the movement, so as to ensure the stability during the threading process. In addition, when the woven bag is bundled by tightening the rope 14, in order to avoid the gap between the rope 14 and the woven bag, the rope 14 needs to be rotated by a certain angle and then tightened and fixed. In this embodiment, after the free end of the rope 14 is introduced and passes through the traction end of the rope 14, the free end of the rope 14 is pulled, which first causes the traction end of the rope 14 to move a certain distance under the force of the rear end of the rack 1. At this time, the free end of the rope 14 is continuously pulled, which causes the traction end of the rope 14 to move downward and gradually close to the woven bag. In this process, the hooking rod 221 rotates, so that the hooking rod 221 is in a downwardly inclined state, and the torsion spring I is twisted to store energy, until the traction end of the rope 14 falls off the hooking rod 221. At this time, the torsion spring I releases the stored energy and drives the hooking rod 221 to return to an upwardly inclined state. Then, the free end of the rope 14 is continuously pulled, so that the rope 14 can be tightened and fixed on the woven bag, so that the rope 14 can be tightened on the woven bag without manual rotation of the rope 14 during the tightening process, so that the woven bag can be better packed.

[0051] In some embodiments, the screw rod driving mechanism includes a chain wheel and chain structure, a rack 31 and a gear 32. The chain wheel and chain structure includes a plurality of chain wheels 33 rotatably arranged on the extrusion plate 12, and a chain 34 in meshing connection with the plurality of chain wheels 33. The plurality of chain wheels 33 are respectively connected with the plurality of screw rods 24. The rack 31 is fixedly arranged on the rack 1 along the height direction of the rack 1. The gear 32 is coaxially arranged with one of the chain wheels 33. The gear 32 and the rack 31 can be in meshing connection. The screw rod 24 is arranged along the length direction of the rope slot 100 and has an outer end penetrating out of the extrusion plate 12. The chain wheel 33 is installed on the outer end of the screw rod 24.

[0052] Specifically, as Figures 4 to 7As shown, the starting drive member 13 drives the extrusion plate 12 to move downward, and simultaneously drives the gear 32 to move synchronously. Through the meshing transmission between the gear 32 and the rack 31, the gear 32 is driven to rotate, and the sprocket 33 coaxially arranged with the gear 32 is driven to rotate. At this time, under the meshing transmission between the chain 34 and the sprocket 33, the plurality of sprockets 33 are driven to rotate, and the screw rod 24 corresponding to the sprocket 33 is driven to rotate. At this time, through the threaded transmission between the screw rod 24 and the moving block 23, the moving block 23 is driven to move along the axial direction of the screw rod 24 to the rear end of the rack 1, and under the action of the self-locking structure, the sliding block 22 is driven to move synchronously with the moving block 23. Until the sliding block 22 and the moving block 23 move to the rear end of the rack 1, at this time, the gear 32 and the rack 31 are disengaged, so that when the extrusion plate 12 continues to move downward, the gear 32 no longer rotates, that is, the sliding block 22 and the moving block 23 stop moving at the rear end of the rack 1.

[0053] Referring to Figure 12 , Figure 13 In some embodiments, the moving block 23 is longitudinally slidably provided with a movable rod 41, and a spring (not shown in the figure) connected with the movable rod 41 is arranged in the moving block 23, and the spring is used to drive the movable rod 41 to move downward. The self-locking structure includes a one-way tooth plate one 42 arranged on the movable rod 41, and a one-way tooth plate two 43 capable of cooperating with the one-way tooth plate one 42. The one-way tooth plate one 42 is arranged on the side of the movable rod 41 close to the sliding block 22, and the side of the sliding block 22 close to the moving block 23 is provided with a groove 223 for the one-way tooth plate one 42 to extend into. The one-way tooth plate two 43 is fixedly arranged in the groove 223, and the lower end of the movable rod 41 is connected with a contact rod 44. When the moving block 23 moves downward, the lower end of the contact rod 44 can contact the rope holder 21, and the contact rod 44 moves upward relative to the moving block 23.[A2]

[0054] Specifically, as Figures 5 to 13As shown, when the moving block 23 gradually approaches the slider 22, it will drive the movable rod 41, which is slidably disposed in the moving block 23, to approach the slider 22 simultaneously. This allows the one-way toothed plate 42 to extend into the groove 223 on the slider 22, and the one-way toothed plate 42 to cooperate with the one-way toothed plate 43 in the groove 223. At this time, the slider 22 and the moving block 23 can move synchronously. When slider 22 and moving block 23 move synchronously to the rear end of frame 1, extrusion plate 12 continues to move downward, driving slider 22, moving block 23, and movable rod 41 to continue moving downward. This causes contact rod 44 at the lower end of movable rod 41 to continue approaching rope holder 21 until the lower end of contact rod 44 contacts rope holder 21. At this time, as extrusion plate 12 continues to move downward, contact rod 44 and movable rod 41 move upward relative to moving block 23. Simultaneously, movable rod 41 compresses the spring connected to it, driving one-way toothed plate 42 to move upward synchronously, causing one-way toothed plate 42 to disengage from one-way toothed plate 43, breaking the connection between slider 22 and moving block 23. At this time, slider 22 can move towards the front end of frame 1 along the axis of screw 24 under the action of reset structure, and drive the traction end of rope 14 to move synchronously through the rope hook rod 221 at the lower end of slider 22, until slider 22 moves to the front end of frame 1, completing the rope threading process of rope 14.

[0055] After the woven bags are packed, the driving component 13 moves the extrusion plate 12 upward, causing the gear 32 to re-mesh with the rack 31. Under this meshing transmission, the gear 32 reverses direction, causing the screw 24 to reverse as well. This, in turn, moves the moving block 23 along the axial direction of the screw 24 towards the slider 22, until the one-way toothed plate 42 re-enters the groove 223 on the slider 22. This allows the one-way toothed plate 42 and the other one-way toothed plate 43 to re-engage, enabling the slider 22 and the moving block 23 to move synchronously for the next rope threading operation.

[0056] In some embodiments, the reset structure includes a winch 5, which is located on the frame 1 at one end away from the rope holder 21. The winch 5 includes a drum 51 and a plurality of pull ropes 52. The drum 51 is rotatably connected to the frame 1 via a torsion spring 2. One end of the pull rope 52 is connected to the drum 51, and the other end passes through the corresponding rope holder groove 100 on the extrusion plate 12 and is connected to the slider 22 in the rope holder groove 100.

[0057] Specifically, such as Figure 1 , Figure 2 , Figure 8As shown, during the process of slider 22 moving from the front end of frame 1 to the rear end of frame 1 along the axial direction of screw 24, the pull rope 52 drives drum 51 to rotate to unwind the line, and causes torsion spring 2 to twist and store energy. After one-way toothed plate 42 moves upward and disengages from one-way toothed plate 43, torsion spring 2 releases its stored energy, driving drum 51 to reverse and rewind the line. At this time, the pull rope 52 can pull slider 22 to move along the axial direction of screw 24 towards the front end of frame 1, and during this process, the traction end of rope 14 moves synchronously through hook rod 221, automatically completing the rope threading process of rope 14.

[0058] Reference Figure 8 , Figure 9 In some embodiments, the frame 1 is provided with a fixing frame 15 for mounting the rope holder 21. The fixing frame 15 is mounted on the packing table 11, and a groove 151 is formed along its height direction on the fixing frame 15. The rope holder 21 is slidably connected to the fixing frame 15 through the groove 151, allowing the rope holder 21 to slide up and down. Furthermore, to improve the stability of the fit between the rope holder 21 and the fixing frame 15, a fixing bolt can be provided on the side of the fixing frame 15. The end of the fixing bolt extends through the fixing frame 15 into the groove 151. After adjusting the position of the rope holder 21, the fixing bolt is rotated so that its end abuts against the side of the rope holder 21 to fix the rope holder 21.

[0059] Specifically, such as Figure 1 , Figure 6 , Figure 8 , Figure 9 As shown, when compressing different numbers of woven bags, the height of the woven bags after compression is inconsistent, which will cause the compression plate 12 to need to descend to different heights. To ensure that the height of the hook rod 221 corresponds to the height of the traction end of the rope 14 on the rope holder 21 when the compression plate 12 stops descending, the rope holder 21 can be slid up and down along the slide groove 151 provided on the fixed frame 15 before packing different numbers of woven bags. The height of the rope holder 21 can be adjusted so that when the compression plate 12 finishes compressing the woven bags, the height of the hook rod 221 is exactly the same as the height of the traction end of the rope 14 on the rope holder 21. This allows the hook rod 221 to be inserted into the traction end of the rope 14 when the slider 22 moves towards the front end of the frame 1, and drives the traction end of the rope 14 to move synchronously to complete the rope threading process of the rope 14.

[0060] like Figure 6 , Figure 8 , Figure 11As shown, the rope holder 21 includes a sliding plate 211 slidably disposed in the sliding groove 151, and a rope holder 212 disposed on the sliding plate 211. The rope holder 212 is disposed on the side of the sliding plate 211 near the rope groove 100, and the end of the rope holder 212 away from the sliding plate 211 gradually tilts upward toward the rope groove 100. Before placing the woven bag on the packing table 11, the rope 14 is placed in the rope groove 100 on the packing table 11, and the pulling end of the rope 14 is hung on the rope holder 212. At the same time, the free end of the rope 14 protrudes out of the rope groove 100. Since the end of the rope holder 212 near the rope groove 100 tilts upward, if the rope 14 is compressed during the placement of the woven bag and the compression of the woven bag, the pulling end of the rope 14 will not fall off the rope holder 212. Instead, the free end of the rope 14 gradually moves into the rope groove 100 to adapt to the shape of the woven bag.

[0061] The implementation principle of the present invention is as follows: First, the height of the extrusion plate 12 is adjusted according to the number of woven bags to be packaged, so that when the extrusion plate 12 is lowered to the limit position, the height of the hook rod 221 corresponds to the height of the traction end of the rope 14 on the rope frame 21.

[0062] Then, place the rope 14 into the rope groove 100 on the packing table 11, and place the pulling end of the rope 14 on the rope rack 21. Then, place the woven bag on the packing table 11.

[0063] Then, the drive unit 13 drives the extrusion plate 12 to move downwards to extrude the woven bag. During this process, the slider 22 and the moving block 23 move synchronously within the rope groove 100 in the extrusion plate 12. When the extrusion plate 12 finishes extruding the woven bag, the slider 22 and the moving block 23 move through the rope groove 100 to the other end of the rope groove 100, that is, from the front end of the frame 1 to the rear end of the frame 1. During the movement of the slider 22 and the moving block 23, the slider 22 drives the drum 51 to rotate through the pull rope 52. In addition, the end of the hook rope rod 221 is inserted into the traction end of the rope 14 as the extrusion plate 12 moves.

[0064] When the extrusion plate 12 moves downward to its limit position, the slider 22 separates from the moving block 23. The torsion spring 2 drives the drum 51 to rotate in the opposite direction to reset. At the same time, the slider 22 moves in the opposite direction through the pull rope 52. The slider 22 drives the traction end of the rope 14 to move to the front end of the frame 1 through the hook rope rod 221. Then the free end of the rope 14 is passed through the traction end and tightened. The rope 14 is under force and drives the hook rope rod 221 to rotate until the rope 14 is separated from the hook rope rod 221. The rope 14 is then tightened and fixed on the woven bag.

[0065] By setting slider 22, moving block 23, and roller 51, the traction end of rope 14 is guided when packing woven bags so that the traction end of rope 14 passes through rope groove 100 to pack the woven bags, thereby improving the packing efficiency of woven bags.

[0066] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
