Description

Technical Field

[0001] This invention relates to the field of warp knitting machine technology, and more particularly to an unwinding and stacking device. Background Technology

[0002] After the warp knitting machine completes the weaving of the fabric, the continuously output fabric needs to be collected and sorted. Existing equipment usually uses rollers to pull and wind the fabric, or uses a separate reciprocating mechanism to lay the fabric flat on a support platform. When using rollers for collection, the fabric tends to form large rolls, which is not convenient for subsequent fixed-length cutting and layered transfer. When using the reciprocating laying method, the traction mechanism and the reciprocating mechanism usually have separate drive sources and require separate speed control. If the two operate out of sync, it can easily cause fabric accumulation, pulling, or uneven stacking spacing.

[0003] In addition, the existing flat-laying equipment's guiding mechanism often continuously clamps the fabric during the reversing process, which can easily pull the already stacked fabric layers, causing the fabric to shift, wrinkle, or become unevenly stacked at the ends; some equipment also requires manual adjustment or pressing of the fabric at both ends of the reciprocating stroke, resulting in a low degree of automation. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an unwinding and stacking device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The unwinding and stacking device includes a support platform, a reciprocating transmission unit, a stacking platform, a pressing assembly, a reciprocating screw frame, a reciprocating stacking assembly, and a take-up roller assembly. The take-up roller assembly is rotatably mounted on the top of the support platform, the stacking platform is located below the take-up roller assembly, the pressing assembly is longitudinally symmetrically arranged on both sides of the stacking platform, and the reciprocating screw frame is laterally arranged on both sides of the stacking platform. The reciprocating transmission unit includes a housing and a transmission assembly disposed therein, the transmission assembly connecting the take-up roller assembly and the reciprocating screw of the reciprocating screw frame. The reciprocating stacking assembly includes a screw slide frame that reciprocates with the screw slide block, a pair of guide rollers disposed between the two screw slide frames, and synchronous adjustment plates disposed on the two screw slide frames respectively. The roller limit frame cooperates with the synchronous adjustment plates to make the guide rollers approach each other during the reciprocating movement and form a gap for clamping the fabric, so as to flatten the fabric during the reciprocating movement and move away from each other when the guide rollers move to the two ends of the reciprocating stroke. At the same time, the screw slide frame is linked with the pressing assembly so that the fabric end on the corresponding side is pressed after the guide roller leaves the end of the reciprocating stroke and is released when the guide roller reaches the end of the reciprocating stroke, so as to reciprocate and flatten the fabric output by the take-up roller assembly onto the stacking table.

[0006] Furthermore, in a preferred configuration, the take-up roller assembly includes a pair of take-up rollers, with both ends of the pair of take-up rollers rotatably mounted on the top of two side support platforms via bearing support seats. Each take-up roller has a sprocket at one end, and a sprocket motor assembly is mounted on the support platform. The sprocket motor assembly is connected to the two sprockets via chains to drive the two take-up rollers to rotate in opposite directions.

[0007] Furthermore, in a preferred configuration, the transmission assembly includes a worm, a worm wheel, a first transmission shaft, a first bevel gear, a second bevel gear, and a second transmission shaft. The worm is longitudinally rotatably disposed within the housing and is connected to one of the take-up rollers. The worm wheel is rotatably disposed at the top of the first transmission shaft and meshes with the worm. The first transmission shaft is vertically connected to the bottom of the worm wheel. The first bevel gear is fixed to the bottom of the first transmission shaft. The second bevel gear is fixed to the horizontally disposed second transmission shaft and meshes with the first bevel gear. The second transmission shaft is fixedly connected to a reciprocating lead screw.

[0008] Furthermore, in a preferred configuration, the reciprocating lead screw frame includes a reciprocating lead screw, a slide guide rail, and a lead screw slide. The slide guide rail is symmetrically arranged laterally on both sides of the stacking platform. The slide guide rail is arranged parallel to the reciprocating lead screw. The lead screw slide is driven and slidably mounted on the slide guide rail with the reciprocating lead screw. The lead screw slide mounting plate is fixedly mounted on the lead screw slide to drive the lead screw slide frame to reciprocate along the reciprocating lead screw frame.

[0009] Furthermore, in a preferred configuration, one bottom side of the lead screw sliding frame is connected to the lead screw slide seat via a lead screw slide seat mounting plate, and a slide rail is provided laterally on the other side; two openings are symmetrically and vertically formed on the lead screw sliding frame, and a second slide rod is symmetrically and vertically arranged on the outer side of the two openings; a third slide rod is vertically arranged in the middle of one side of the lead screw slide frame located on the lead screw slide seat mounting plate, and a second spring is sleeved on the third slide rod; connecting rods are symmetrically and rotatably arranged on both sides of the lead screw sliding frame located on the slide rail, and a first roller is rotatably arranged at the end of each connecting rod away from the lead screw sliding frame.

[0010] In addition, a preferred structure is that two sliders are symmetrically slidably arranged on the slide rail, each slider is provided with a bearing seat, and a guide roller is rotatably arranged between the corresponding bearing seats on the two sides of the lead screw sliding frame via a rotating shaft; a second roller is rotatably arranged on the side of each slider away from the guide roller, the second roller passes through the corresponding opening and cooperates with the synchronous adjustment plate.

[0011] Furthermore, in a preferred configuration, roller limiting grooves are obliquely arranged on both sides of the synchronous adjustment plate, and the second roller is rolled within the corresponding roller limiting groove; a first slider is arranged at the top center of one side of the synchronous adjustment plate, and the first slider is vertically slidably arranged on the third slide rod, with a second spring abutting between the first slider and the lead screw sliding frame; second sliders are symmetrically arranged at the bottom of both ends of the synchronous adjustment plate, and the second sliders are slidably arranged on the second slide rod, with a third roller rotatably arranged on the side of the synchronous adjustment plate away from the first slider.

[0012] In addition, a preferred structure is that the roller limiting frame includes multiple support plates and roller limiting slide rails. The multiple support plates are spaced apart on one side along the length direction of the reciprocating screw frame. The roller limiting slide rails are fixed on the multiple support plates. The roller limiting slide rails include a pressure roller part and release parts located at both ends of the pressure roller part. The third roller is tumbling within the roller limiting slide rail. The pressure roller is used to press against the third roller, causing the synchronous adjustment plate to overcome the elastic force of the second spring and generate displacement. The roller limiting slide groove and the second roller drive the two guide rollers to move closer to each other. The release part is used to release the pressure on the third roller, causing the second spring to drive the synchronous adjustment plate to reset and move the two guide rollers away from each other.

[0013] Furthermore, in a preferred configuration, the pressing assembly includes a pressing plate and lifting frames disposed at both ends of the pressing plate. The pressing plate includes a pressing plate, a side sliding bracket, and a roller limiting plate. The side sliding bracket is disposed at both ends of the pressing plate, and the roller limiting plate is connected to the side sliding bracket. The lifting frame includes a first sliding rod and a first spring sleeved on the first sliding rod, and the side sliding bracket is slidably disposed on the first sliding rod. When the lead screw slide frame moves to the end of the reciprocating stroke, the first roller presses against the roller limiting plate, causing the pressing plate to rise and release the fabric. When the lead screw slide frame leaves the end of the reciprocating stroke, the first roller separates from the roller limiting plate, and the first spring pushes the pressing plate down and presses the fabric.

[0014] The beneficial effects of this invention are as follows: This invention simultaneously drives the fabric conveying and transmission components through the take-up roller assembly, and the transmission component drives the reciprocating screw frame to work, so that the fabric conveying speed and the reciprocating movement of the reciprocating stacking component are mechanically synchronized; the roller limit frame is linked with the synchronous adjustment plate, so that the guide roller lightly clamps and flattens the fabric during the movement and automatically separates it at the end of the stroke; at the same time, the screw sliding frame drives the pressing component to release the fabric when the guide roller changes direction, and then presses the fabric again after leaving the end. The above mechanisms work together to complete traction, flattening, release, pressing and reversing stacking, reducing independent driving and manual handling, so that the fabric can be continuously and neatly stacked on the stacking table.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figure 1-19 The unwinding and stacking device includes a support platform 01, a reciprocating transmission unit 02, a stacking platform 03, a pressing assembly 04, a reciprocating screw frame 05, a reciprocating stacking assembly 06, and a take-up roller assembly 1. The take-up roller assembly 1 is rotatably mounted on top of the support platform 01, and the stacking platform 03 is positioned below the take-up roller assembly 1, used to receive and stack the fabric produced by the warp knitting machine. The pressing assembly 04 is longitudinally symmetrically arranged on both sides of the stacking platform 03, used to press or release the ends of the fabric stacked on the stacking platform 03. The reciprocating screw frame 05 is laterally arranged on both sides of the stacking platform 03, and the reciprocating stacking assembly 06 is installed between the two reciprocating screw frames 05 to reciprocate above the stacking platform 03.

[0019] The take-up roller assembly 1 includes a pair of take-up rollers 11, which are rotatably mounted on the top of the two side support platforms 01 via bearing support seats 13. Each take-up roller 11 has a sprocket 12 fixedly mounted at one end. A sprocket motor assembly 011 is mounted on the support platform 01, and the sprocket motor assembly 011 is connected to the two sprockets 12 via corresponding chains.

[0020] When the sprocket motor assembly 011 is working, it drives two sprockets 12 to rotate via a chain, causing the two take-up rollers 11 to rotate in opposite directions. The fabric produced by the warp knitting machine passes between the two take-up rollers 11, and the two take-up rollers 11, through their opposite rotation, jointly pull the fabric, continuously conveying it to the stacking table 03 located below them. The sprocket motor assembly 011 uses a conventional chain drive drive component consisting of a motor, sprockets, and chain, and its specific model and transmission ratio can be selected according to the fabric conveying speed.

[0021] The reciprocating transmission unit 02 includes a housing 021 and a transmission assembly 2 disposed inside the housing 021. The housing 021 is used to install and protect the transmission assembly 2. One end of the transmission assembly 2 is connected to one of the take-up rollers 11, and the other end is connected to the reciprocating screw 051 of the reciprocating screw frame 05, so that the take-up roller assembly 1 can synchronously drive the reciprocating lamination assembly 06 to reciprocate while conveying the fabric.

[0022] Specifically, the transmission assembly 2 includes a worm 21, a worm gear 22, a first transmission shaft 23, a first bevel gear 24, a second bevel gear 25, and a second transmission shaft 26. The worm 21 is longitudinally rotatably disposed inside the housing 021 and is connected to one of the take-up rollers 11, so that when the take-up roller 11 rotates, it can synchronously drive the worm 21 to rotate.

[0023] The worm gear 22 is vertically rotatable within the housing 021 and meshes with the worm 21. The first drive shaft 23 is vertically connected to the bottom of the worm gear 22, and the first bevel gear 24 is fixedly mounted on the bottom of the first drive shaft 23. The second drive shaft 26 is horizontally positioned at the lower part of the housing 021, and the second bevel gear 25 is fixedly mounted on the second drive shaft 26 and meshes with the first bevel gear 24.

[0024] When the worm 21 rotates with the take-up roller 11, the worm 21 drives the worm wheel 22 and the first drive shaft 23 to rotate through meshing with the worm wheel 22. The first drive shaft 23 drives the first bevel gear 24 to rotate, and the first bevel gear 24 drives the second drive shaft 26 to rotate laterally through meshing with the second bevel gear 25. The second drive shaft 26 is fixedly connected to the reciprocating screw 051, thereby transmitting the rotational power of the take-up roller assembly 1 to the reciprocating screw frame 05, so that the fabric conveying process and the reciprocating flat laying process of the fabric are linked.

[0025] The reciprocating screw holder 05 includes a reciprocating screw 051, a slide guide rail 052, and a screw slide 053. The two reciprocating screw holders 05 are symmetrically arranged laterally on both sides of the stacking platform 03. The slide guide rail 052 is parallel to the reciprocating screw 051. The screw slide 053 is in transmission cooperation with the reciprocating screw 051 and is slidably arranged on the slide guide rail 052.

[0026] When the reciprocating lead screw 051 rotates, it drives the lead screw slide 053 to move along the slide guide rail 052 via the reciprocating helical trajectory on the lead screw 051. When the lead screw slide 053 moves to one end of the reciprocating lead screw 051, the lead screw slide 053 automatically changes its direction of movement along the reciprocating helical trajectory, so that while the reciprocating lead screw 051 continues to rotate, the lead screw slide 053 continuously reciprocates along the slide guide rail 052.

[0027] A screw slide mounting plate 45 is fixedly installed on the screw slide 053, and one bottom side of the screw sliding frame 4 is mounted on the screw slide 053 via the screw slide mounting plate 45. Therefore, when the screw slide 053 moves along the slide guide rail 052, it can drive the screw sliding frame 4 to move synchronously via the screw slide mounting plate 45.

[0028] The reciprocating lamination assembly 06 includes a screw slide frame 4 disposed on two reciprocating screw frames 05, a pair of guide rollers 5 disposed between the two screw slide frames 4, and a synchronous adjustment plate 6 disposed on the screw slide frame 4. The two screw slide frames 4 are interconnected by the pair of guide rollers 5, so that the two screw slide frames 4 can move synchronously along the corresponding reciprocating screw frames 05.

[0029] A slide rail 42 is laterally arranged on the side of the lead screw sliding frame 4 away from the lead screw slide mounting plate 45. Two sliders 53 are symmetrically slidably arranged on the slide rail 42, and each slider 53 is provided with a bearing seat 52. A guide roller 5 is arranged between the corresponding bearing seats 52 on the two sides of the lead screw sliding frame 4. The two ends of the guide roller 5 are rotatably mounted in the corresponding bearing seats 52 through the rotating shaft 51, so that the guide roller 5 can rotate freely relative to the bearing seat 52.

[0030] The two sliders 53 can move closer or further apart along the slide rail 42, thereby causing the two guide rollers 5 to move closer or further apart. When the two guide rollers 5 move closer together, a gap is formed between them for slightly clamping the fabric. This clamping force is used to limit wrinkles and shifts in the fabric during the laying process, but does not forcibly pull the fabric away from the take-up roller assembly 1, and the fabric continues to be fed downwards by the take-up roller assembly 1.

[0031] Each slider 53 has a second roller 54 rotatably mounted on the side away from the guide roller 5. Two openings 41 are symmetrically opened through the screw slide frame 4, and the second roller 54 passes through the corresponding opening 41 and rolls in cooperation with the synchronous adjustment plate 6 located on the other side of the screw slide frame 4.

[0032] The synchronous adjustment plate 6 has roller limiting grooves 61 inclinedly arranged on both sides. The two roller limiting grooves 61 are symmetrically arranged about the middle of the synchronous adjustment plate 6, and the two second rollers 54 are respectively rolled in the corresponding roller limiting grooves 61. When the synchronous adjustment plate 6 moves vertically, the inclined roller limiting grooves 61 can drive the sliders 53 on both sides to move synchronously in opposite directions along the slide rail 42 through the second rollers 54, so that the two guide rollers 5 move closer or further away synchronously.

[0033] A third slide rod 47 is vertically arranged in the middle of one side of the lead screw slide mounting plate 45, and a first slider 63 is arranged in the top middle of the synchronous adjustment plate 6 near the third slide rod 47. The first slider 63 is vertically slidably arranged on the third slide rod 47. A second spring 48 is sleeved on the third slide rod 47, and the second spring 48 abuts between the first slider 63 and the lead screw slide frame 4, and is used to apply a reset force to the synchronous adjustment plate 6.

[0034] Symmetrically arranged vertically on the outer sides of the two openings 41 are second slide rods 46. Symmetrically arranged on the bottom of both ends of the synchronous adjustment plate 6, on the same side as the first slide rod 63, are second slide blocks 64. The two second slide blocks 64 are slidably mounted on their respective second slide rods 46. The first slide rod 63 cooperates with the third slide rod 47, and the two second slide blocks 64 cooperate with the two second slide rods 46, together restricting the movement direction of the synchronous adjustment plate 6, so that the synchronous adjustment plate 6 can stably rise and fall relative to the lead screw sliding frame 4.

[0035] A third roller 62 is rotatably mounted on the side of the synchronous adjustment plate 6 away from the first slider 63. A roller limiting frame 3 is mounted on one side of the reciprocating screw frame 05. The roller limiting frame 3 includes multiple support plates 31 and roller limiting slide rails 32. The multiple support plates 31 are spaced apart along the length of the reciprocating screw frame 05, and the roller limiting slide rails 32 are fixedly mounted on the multiple support plates 31.

[0036] The roller limiting slide rail 32 includes a pressure roller portion 321 located in the middle and release portions 322 located at both ends of the pressure roller portion 321. The third roller 62 rolls within the roller limiting slide rail 32 and moves synchronously with the lead screw sliding frame 4 along the reciprocating lead screw frame 05.

[0037] When the lead screw sliding frame 4 is in the middle region of the reciprocating stroke, the third roller 62 is pressed by the pressure roller part 321, causing the synchronous adjusting plate 6 to overcome the elastic force of the second spring 48 and move along the third slide rod 47 and the second slide rod 46. During the movement of the synchronous adjusting plate 6, the two inclined roller limiting grooves 61 respectively push the two second rollers 54, causing the two sliders 53 to move closer to each other along the slide rail 42, thereby driving the two guide rollers 5 to move closer to each other and slightly clamp the fabric.

[0038] At this time, the two guide rollers 5 move laterally above the stacking platform 03 along with the lead screw sliding frame 4. While slightly clamping the fabric, the two guide rollers 5 can rotate around their respective pivots 51, thereby guiding and flattening the continuously falling fabric, so that the fabric is laid flat on the stacking platform 03 in the direction of movement of the guide rollers 5.

[0039] When the lead screw slide 4 moves to one end of the reciprocating stroke, the third roller 62 moves from the pressure roller part 321 into the corresponding release part 322. The release part 322 releases the pressure on the third roller 62, the second spring 48 releases its elastic potential energy and pushes the first slider 63 to reset along the third slide rod 47, so that the synchronous adjustment plate 6 resets synchronously.

[0040] When the synchronous adjustment plate 6 is reset, the two roller limit grooves 61 drive the two sliders 53 to move away from each other along the slide rail 42 through the two second rollers 54, so that the two guide rollers 5 separate from each other and no longer hold the fabric. The two guide rollers 5 release the fabric at the end of the reciprocating stroke, which can prevent the guide rollers 5 from pulling the fabric that has been laid flat on the stacking table 03 when they change direction.

[0041] The pressing assembly 04 includes a pressing plate 041 and lifting frames 042 disposed at both ends of the pressing plate 041. The pressing plate 041 includes a pressing board 0411, a side sliding bracket 0412, and a roller limiting plate 0413. The pressing plate 0411 is horizontally disposed above the end of the stacking table 03, and a side sliding bracket 0412 is disposed at each end of the pressing plate 0411. A roller limiting plate 0413 is connected to each side sliding bracket 0412.

[0042] The lifting frame 042 includes a first slide rod 0421 and a first spring 0422 sleeved on the first slide rod 0421. The side sliding bracket 0412 is vertically slidably disposed on the first slide rod 0421. The first spring 0422 is used to apply a downward elastic force to the side sliding bracket 0412 and the pressing plate 0411, so that the pressing plate 0411 can press the end of the fabric when it is not subjected to external force.

[0043] The lead screw slide frame 4 is symmetrically and rotatably equipped with connecting rods 43 on both sides of the slide rail 42. Each connecting rod 43 has a first roller 44 rotatably mounted at the end away from the lead screw slide frame 4. The first roller 44 moves synchronously with the lead screw slide frame 4 along the reciprocating lead screw frame 05.

[0044] When the lead screw sliding frame 4 approaches the end of the reciprocating stroke, the first roller 44 contacts the roller limiting pressure plate 0413 of the corresponding pressing assembly 04. As the lead screw sliding frame 4 continues to move towards the end, the first roller 44 lifts the roller limiting pressure plate 0413, and the roller limiting pressure plate 0413 drives the pressing plate 0411 to rise along the first slide rod 0421 through the side sliding bracket 0412, while compressing the first spring 0422, so that the pressing plate 0411 separates from the fabric and releases the end of the fabric.

[0045] When the lead screw sliding frame 4 reaches the end of the reciprocating stroke, the two guide rollers 5 move away from each other under the action of the release part 322 and the second spring 48, while the pressure plate 0411 rises under the pushing action of the first roller 44. Thus, the guide rollers 5 and the pressure assembly 04 can release the fabric synchronously at the end of the reciprocating stroke, allowing the fabric to naturally turn and form a new stacked layer.

[0046] When the lead screw slide 053 reverses direction along the reciprocating lead screw 051, the lead screw slide bracket 4 begins to move to the other end. The first roller 44 gradually separates from the roller limiting pressure plate 0413, and the first spring 0422 releases its elastic potential energy, pushing the side sliding bracket 0412 and the fabric pressing plate 0411 downward, so that the fabric pressing plate 0411 presses down on the end of the fabric again.

[0047] Meanwhile, the third roller 62 re-enters the pressure roller section 321 from the release section 322. The pressure roller section 321 applies pressure to the third roller 62, causing the synchronous adjustment plate 6 to shift again and drive the two guide rollers 5 to move closer to each other. The two guide rollers 5 lightly clamp the fabric again and move with the screw sliding frame 4 to the other end of the stacking table 03, flattening the subsequently falling fabric in the opposite direction.

[0048] In this embodiment, when the device is working, the fabric produced by the warp knitting machine is first passed between the two take-up rollers 11, and the end of the fabric enters between the two guide rollers 5 and falls onto the stacking table 03. The sprocket motor unit 011 is started, and the two take-up rollers 11 rotate in opposite directions and continuously convey the fabric downward.

[0049] The unwinding process refers to the continuous release and conveying of the fabric continuously output by the warp knitting machine to the stacking table 03 by the take-up roller assembly 1.

[0050] One of the take-up rollers 11 synchronously drives the worm gear 21 to rotate. The worm gear 21 drives the reciprocating lead screw 051 to rotate in sequence through the worm wheel 22, the first drive shaft 23, the first bevel gear 24, the second bevel gear 25, and the second drive shaft 26. The reciprocating lead screw 051 drives the lead screw slide 053, the lead screw slide mounting plate 45, the lead screw sliding frame 4, and the guide roller 5 to move back and forth above the stacking platform 03.

[0051] As the guide roller 5 moves from one end of the stacking platform 03 to the other, the pressure roller 321 brings the two guide rollers 5 closer together through the third roller 62 and the synchronous adjustment plate 6. The two guide rollers 5 slightly clamp and flatten the fabric. At the same time, the pressure plate 0411 located at the starting end of the movement presses down on the end of the already stacked fabric under the action of the first spring 0422 to prevent the fabric from shifting as it moves with the guide roller 5.

[0052] When the guide roller 5 moves to the other end, the release part 322 cooperates with the second spring 48 to move the two guide rollers 5 away from each other and release the fabric; at the same time, the first roller 44 pushes up the corresponding roller limiting pressure plate 0413, causing the corresponding pressure plate 0411 to rise and release the fabric. After the fabric forms a turn at this end, the screw slide 053 changes its direction of movement, and the guide roller 5 begins to move in the opposite direction.

[0053] After the guide roller 5 leaves the end, the first roller 44 separates from the roller limiting plate 0413, and the corresponding pressing plate 0411 descends again to press the end of the fabric; the third roller 62 re-enters the pressing roller section 321, causing the two guide rollers 5 to come closer together again and slightly clamp the fabric. The guide roller 5 then flattens the fabric in the opposite direction.

[0054] By repeating the above process, the fabric continuously output by the warp knitting machine can be laid flat layer by layer on the stacking table 03 in opposite directions, forming a neat stacked fabric structure. After the predetermined number of layers or the predetermined length of fabric are stacked, the sprocket motor unit 011 can be stopped, and the stacked fabric can then be further cut and transferred.

[0055] In this invention, the take-up roller assembly 1 simultaneously drives the fabric conveying and transmission assembly 2, and the transmission assembly 2 drives the reciprocating screw frame 05 to work, so that the fabric conveying speed and the reciprocating movement of the reciprocating stacking assembly 06 are mechanically synchronized; the roller limit frame 3 is linked with the synchronous adjustment plate 6, so that the guide roller 5 lightly clamps and flattens the fabric during the movement and automatically separates at the end of the stroke; at the same time, the screw sliding frame 4 drives the pressing assembly 04 to release the fabric when the guide roller 5 changes direction, and presses the fabric again after leaving the end. The above mechanisms work together to complete traction, flattening, release, pressing and reversing stacking, reducing independent driving and manual handling, so that the fabric can be continuously and neatly stacked on the stacking table 03.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
