Description

Technical Field

[0001] This invention relates to the field of strip flattening, handling, and automatic winding technology, and particularly to a flattening, conveying, and winding device for stretching and shaping. Background Technology

[0002] In the manufacturing process of textile fabrics, stretching and setting are usually required to eliminate internal stress generated in the early stages of processing, stabilize the fabric width, and maintain a smooth fabric surface. Existing stretching and setting flattening conveyor and winding devices generally consist of a frame, a feed conveyor roller group, a tension control mechanism, and a rear-end power winding mechanism. The conventional assembly line operation logic is as follows: using the rotation of the winding shaft as the traction force, the fabric is guided sequentially through various stages of rigid conveyor rollers or passive guide rollers, ultimately continuously winding the wide-width fabric into a standard roll for subsequent storage and transportation.

[0003] However, in actual textile finishing processes, after the fabric is set by the tenter frame, it usually falls into a scattered and disordered pile into the temporary storage area. Subsequently, the next equipment needs to extract the fabric from the pile, guide it through the conveyor rollers, and finally wind it onto the take-up rollers. During this process, the fabric between the pile and the first conveyor roller is in a completely relaxed and tension-free state. To prevent the fabric from entering the take-up stage in a disordered state, current production processes usually require workers to apply an axial tensile force towards the outside of the fabric edge through their hands in the suspended transition area before the fabric enters the conveyor rollers, on both sides of the inlet. This keeps the fabric edge in a controlled lateral constraint state, thus manually straightening the fabric and preventing wrinkles during subsequent take-up. However, manual force is difficult to maintain evenly and consistently, affecting the consistency of the take-up operation. Summary of the Invention

[0004] This invention provides a flattening conveying and winding device for stretching and shaping, which solves the problem of loose undulations in the fabric before entering the conveying rollers due to lack of tension constraint. The fabric is straightened by continuously applying lateral stretching constraint on both sides manually, but the manual force is difficult to maintain evenly and affects the consistency of the winding operation.

[0005] The present invention adopts the following technical solution: a flattening conveyor and take-up device for stretching and shaping. It includes a take-up frame with guide rollers for supporting and guiding the fabric; The take-up assembly, located on one side of the take-up frame, is used to take up the fabric. Two flattening and expanding components are symmetrically arranged on both sides of the take-up frame. They include a clamping unit that moves back and forth toward both sides of the fabric, and a guide unit that is correspondingly arranged outside the clamping unit. The clamping unit has a movable clamping end for clamping from both sides of the fabric. The guide unit abuts and cooperates with the movable clamping end to form a constraint. When the clamping unit is displaced, it guides the movable clamping end to continuously perform a cyclic action of closing to grip the fabric, pulling it laterally to the outside, and releasing the force. A limiting component, fixedly mounted on the flattening and expanding component, is used to limit the fabric passing through the touch clamp unit to restrict its vertical movement.

[0006] Furthermore, the flattening and expanding assembly also includes an installation unit, a reset unit, a linear movement module, and a horizontal drive unit. The installation unit is fixed on the winding frame, and the linear movement module is set on the bottom surface of the installation unit to adjust the lateral spacing between the two flattening and expanding assemblies on both sides of the fabric. The movable clamping end includes a C-shaped contact clip and two movable clamping plates. The C-shaped contact clip is slidably mounted on the mounting unit, and the two movable clamping plates are respectively movably mounted through the horizontal end of the C-shaped contact clip. The reset unit is connected between the C-shaped contact clip and the mounting unit, and the horizontal drive unit is mounted on the mounting unit and abuts against the C-shaped contact clip to push the C-shaped contact clip to move horizontally back and forth.

[0007] Furthermore, the touch clamp unit also includes a guide rod, a contact frame, a support spring, and universal balls. Each movable clamp plate is fixed with a guide rod, which is movably installed through the horizontal end of the C-shaped touch clamp. The contact frame is fixed to one end of the guide rod. The support spring is sleeved on the guide rod and its two ends are respectively connected between the outer surface of the C-shaped touch clamp and the contact frame. It is used to provide the opening elastic force of the two movable clamp plates by default, keeping the movable clamp plates in default fit against the inner wall of the upper and lower horizontal ends of the C-shaped touch clamp. Several universal balls are provided and movably embedded on the side of the two movable clamp plates that are close to each other. They are used to contact the fabric and allow the fabric to pass through when it is stretched.

[0008] Furthermore, the flattening and expanding assembly also includes a triggering unit, which includes a horizontal slot box, a sliding block, and a triggering rod. The horizontal slot box is horizontally arranged and parallel to and perpendicular to the contact frame. The sliding block is slidably arranged on the horizontal slot box, and the triggering rod is vertically fixed on the sliding block. The trigger rod consists of nested inner and outer sleeve rods connected by a connecting spring to facilitate relative axial sliding in the vertical direction. The guide unit is used to press the trigger rod in the vertical direction to drive the contact frame down through the trigger rod and close the movable clamp.

[0009] Furthermore, the guide unit includes a track plate, the number of which corresponds to the number of movable clamps and is fixed to the mounting unit by a bracket. The track plate has a first groove and a second groove that are connected. In the default state, the trigger rod is at the starting position at one end of the first groove. The bottom of the first groove has a gradually rising slope. The end of the first groove has a horizontal section with a horizontal bottom and a groove width that matches the diameter of the trigger rod. This section is used to keep the two movable clamps closed and clamping the side of the fabric when the trigger rod moves to the horizontal section. The second groove is connected to the end of the horizontal section and is used to allow the trigger rod to slide in when the C-shaped contact clamp moves outward to stretch the fabric.

[0010] Furthermore, the track plate is also provided with a third slide groove, which is connected to one end of the second slide groove. A first step is provided at the junction of the first slide groove and the second slide groove, which is used to guide the trigger rod to slide into the second slide groove in one direction by utilizing the height difference of the first step. The second slide groove has a holding section with a horizontal bottom near the end that communicates with the first slide groove. This section is used to maintain the clamping state of the movable clamping plate on the edge of the fabric when the trigger rod slides along the holding section. The bottom of the third slide groove is inclined downwards. This is used to gradually reduce the pressing pressure on the movable clamping plate by lowering the height of the bottom of the third slide groove when the trigger rod slides along the third slide groove, so that the movable clamping plate can be reset and the fabric can be released.

[0011] Furthermore, one end of the third slide groove is connected to the first slide groove, which is used to guide the trigger rod back to the initial low point position at the starting end of the first slide groove. The connection between the third slide groove and the first slide groove has a second step, which is used to make the trigger rod slide only unidirectionally along the first slide groove when it is initially subjected to force in the next action cycle by utilizing the height difference of the second step. When the trigger rod slides into the second slide groove and the third slide groove in sequence, the upper end of the trigger rod simultaneously slides relative to the horizontal slot box with the help of the sliding block, which is used to provide lateral displacement compensation.

[0012] Furthermore, the installation unit includes an installation frame, an installation shell, a sliding base, and a slide rail. The installation frame is disposed on the side of the winding assembly frame, the installation shell is fixed to the side of the installation frame, the sliding base is disposed inside the installation shell, the slide rail is fixed on the sliding base, and the C-shaped contact clip is slidably disposed on the slide rail. The horizontal drive unit includes a mounting base, a drive motor, and an eccentric cam. The mounting base is fixed to the side of the sliding base, the drive motor is vertically fixed to the bottom surface of the mounting base, and the eccentric cam is fixed to the output end of the drive motor and is always in contact with the side of the C-shaped contact clip, used to push the C-shaped contact clip to move horizontally back to its reset position. The reset unit includes four shaft pins and two tension springs. Two pins are fixed on both sides of the C-shaped contact clip, and two other pins are fixed on the upper surface of the sliding base. Two tension springs are symmetrically arranged on both sides of the C-shaped contact clip, and the two ends of each tension spring are respectively connected between a pin on the side of the corresponding C-shaped contact clip and a pin on the upper surface of the sliding base, which is used to provide a balanced reset force after the C-shaped contact clip is pushed by the eccentric cam.

[0013] Furthermore, the linear motion module includes a concave seat, a lead screw, a load-bearing slider, and a servo motor. The concave seat is fixed to the mounting shell by a bracket, the lead screw is mounted on the concave seat by a bearing, the load-bearing slider is drivenly connected to the lead screw and connected to the bottom surface of the sliding base, and the servo motor is fixed to one end of the concave seat and drivenly connected to the lead screw.

[0014] Furthermore, the limiting component includes two mounting side frames and two constraint rollers. The two mounting side frames are symmetrical and fixed to the sides of the corresponding mounting shells. The two constraint rollers are horizontally arranged between the two mounting side frames and are arranged parallel to each other vertically, so as to allow the fabric to pass between the two constraint rollers to limit the up-and-down floating of the fabric due to winding.

[0015] The technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects: A flattening conveying and winding device for stretching and shaping is disclosed. This invention symmetrically arranges flattening and expanding components on both sides of the winding frame. Utilizing the contact constraint cooperation between the clamping unit and the guiding unit, as the clamping unit moves back and forth toward both sides of the fabric, it guides the movable clamping end to continuously and automatically close and grasp the fabric, stretch it laterally to the outside, and release the force in a cyclical action. This structure effectively replaces the traditional operation in existing processes that relies on manual hands to apply a lateral stretching force to the edge of the fabric in the suspended area. This not only reduces labor intensity but also applies a uniform, lasting, and consistent lateral flattening force to the fabric in a relaxed state through mechanized regular cyclic stretching, automatically straightening the fabric and effectively eliminating curls and wrinkles before entering the winding stage. At the same time, the limiting components fixed on the flattening and expanding components implement upper and lower limit constraints on the fabric passing through the clamping unit, forcibly restricting the fabric from floating up and down during the transfer process, ensuring that the fabric is supported and guided by the guide roller group with extremely high flatness and stability, and finally completed by the winding and winding components, which improves the consistency of the fabric winding operation and the continuity of the overall production.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-8 As shown, this embodiment provides a flattening conveying and winding device for stretching and shaping, including a winding frame 2 with guide rollers 23 for supporting and guiding the fabric; a winding assembly 3, disposed on one side of the winding frame 2, for winding and winding the fabric; two flattening and expanding assemblies 4, symmetrically disposed on both sides of the winding frame 2, including a clamping unit 44 that reciprocates toward both sides of the fabric, and a guide unit 48 correspondingly disposed outside the clamping unit 44. The clamping unit 44 has a movable clamping end for clamping from both sides of the fabric edge, and the guide unit 48 abuts and cooperates with the movable clamping end to form a constraint, for guiding the movable clamping end to continuously perform a cyclic action of closing and gripping the fabric, stretching it laterally to the outside, and releasing the force when the clamping unit 44 is displaced; and a limiting assembly 5, fixedly disposed on the flattening and expanding assembly 4, for limiting the fabric passing through the clamping unit 44 to restrict its vertical floating.

[0022] The working principle of this device is as follows: When the fabric is conveyed forward, the flattening and expanding components 4 symmetrically arranged on both sides, through the transmission cooperation between the clamping unit 44 and the guiding unit 48, cause the movable clamping end to move horizontally back and forth. When moving outward, it closes and grabs the edge of the fabric and pulls it outward laterally to expand it. When returning, it releases the force and releases the fabric. This cyclic action eliminates the curling or wrinkles of the fabric. The flattened fabric passes through the limiting component 5 and is rigidly limited and constrained in the vertical direction by the limiting component 5, which inhibits the fabric from floating up and down under the high tension of subsequent winding. This ensures that the fabric is conveyed smoothly in a flattened and straightened state. Finally, the fabric is supported and guided by the guide roller group 23 and enters the winding component 3 for power winding into a roll.

[0023] To achieve the guiding support and load-bearing capacity of the fabric, refer to Figures 1-2 As shown, the winding frame 2 includes a support frame 21 and a control box 22. The control box 22 is fixed on one side of the outer wall of the support frame 21 and is used to house electrical control components and drive the movement of the whole machine. The guide roller group 23 is horizontally assembled on the support frame 21 and is used to support and guide the fabric running at multiple points.

[0024] To achieve dynamic winding and recovery of the rolled fabric, continue to refer to... Figures 1-2 As shown, the winding assembly 3 includes a winding base 31 and a limiting frame 32. The winding base 31 is located on one side of the support frame 21, and two limiting frames 32 are symmetrically arranged and both are located on the winding base 31. During the winding operation, the winding shaft is mounted between the two limiting frames 32. An external drive source drives the winding shaft to rotate, applying a constant longitudinal pulling force to the fabric, and continuously winding and collecting the straightened fabric.

[0025] To achieve the installation of the flattening and expansion component 4, refer to... Figures 4-6As shown, the installation unit includes an installation frame 41, an installation shell 42, a sliding base 43, and a slide rail 446. The installation frame 41 is located on the side of the support frame 21 of the winding assembly frame 2, and two are symmetrically arranged. The installation shell 42 is fixed to the side of the corresponding installation frame 41, and its interior forms a shell with a protective and accommodating space. The sliding base 43 is located inside the installation shell 42, and its upper surface is fixed with a slide rail 446 in the horizontal direction. The C-shaped contact clip 441 of the contact clip unit 44 is slidably assembled on the slide rail 446 by a slider. The C-shaped contact clip 441 is adapted to slide along the linear direction of the slide rail 446 on the sliding base 43.

[0026] To adjust the lateral spacing between the two flattening and expanding components 4 to accommodate different fabric widths, continue referring to... Figures 4-6 As shown, the linear motion module 46 includes a concave seat 461, a lead screw 462, a bearing slider 463, and a servo motor 464. The concave seat 461 is fixed on the mounting shell 42 by a bracket. The lead screw 462 is mounted on the concave seat 461 by a bearing. The bearing slider 463 is drivenly connected to the lead screw 462 and connected to the bottom surface of the sliding base 43. The servo motor 464 is fixed to one end of the concave seat 461 and drivenly connected to the lead screw 462.

[0027] When processing fabrics of different widths, the servo motor 464 is started to rotate by the control box 22 and the lead screw 462 is rotated to drive the carrying slider 463 to make horizontal linear displacement, and drive the sliding base 43 and the entire component on it to move synchronously inward or outward along the horizontal, adjusting and locking the overall lateral spacing between the two flattening and expanding components 4.

[0028] To drive the C-shaped contact clip 441 to perform high-frequency horizontal reciprocating linear displacement to flatten it, refer to Figures 6-7 As shown, the horizontal drive unit 47 includes a mounting base 471, a drive motor 472, and an eccentric cam 473. The mounting base 471 is fixed to the side of the sliding base 43, the drive motor 472 is vertically fixed to the bottom surface of the mounting base 471, and the eccentric cam 473 is fixed to the output end of the drive motor 472 and is always in contact with the side of the C-shaped contact clip 441. The reset unit includes four pins 447 and two tension springs 448. Two pins 447 are fixed on both sides of the C-shaped contact clip 441, and the other two pins 447 are fixed on the upper surface of the sliding base 43. The two tension springs 448 are symmetrically arranged on both sides of the C-shaped contact clip 441, and the two ends of each tension spring 448 are respectively connected between a pin 447 on the side of the corresponding C-shaped contact clip 441 and a pin 447 on the upper surface of the sliding base 43.

[0029] During the reciprocating linear displacement stroke, the drive motor 472 maintains a constant speed rotation and drives the eccentric cam 473 to rotate accordingly. When the large diameter flange profile of the eccentric cam 473 rotates to abut against the side of the C-shaped contact clip 441, it pushes the C-shaped contact clip 441 to overcome the tension of the tension spring 448 and move it outward along the slide rail 446. At this time, the two tension springs 448 are stretched and store elastic potential energy. When the eccentric cam 473 rotates to the small diameter surface, the two tension springs 448 release the elastic potential energy and pull back the C-shaped contact clip 441 so that it slides inward along the slide rail 446 to reset, thereby forming a continuous reciprocating linear motion.

[0030] To achieve the clamping and flattening of the fabric edges during the reciprocating movement, continue referring to... Figures 6-7 As shown, the movable clamping end includes a C-shaped contact clamp 441 and two movable clamping plates 442. The two movable clamping plates 442 are respectively movably disposed through the horizontal end of the C-shaped contact clamp 441. The contact clamping unit 44 also includes a guide rod, a contact frame 443, a support spring 444 and several universal balls 445. Each movable clamping plate 442 is fixed with a guide rod, which is movably disposed through the horizontal end of the C-shaped contact clamp 441. The contact frame 443 is fixed to one end of the guide rod. The support spring 444 is sleeved on the guide rod and its two ends are respectively connected between the outer surface of the C-shaped contact clamp 441 and the contact frame 443. Several universal balls 445 are movably embedded on the side of the two movable clamping plates 442 that are close to each other.

[0031] During the clamping and fabric translation process, the support spring 444 continuously stretches the contact frame 443 under the default state of no external force, thereby keeping the two movable clamping plates 442 away from each other through the guide rod. Even if the movable clamping plates 442 are in the default open state, they are pressed against the inner walls of the upper and lower horizontal ends of the C-shaped contact clamp 441 to maintain the feeding gap. When the two movable clamping plates 442 are closed by external downward pressure, the two sets of universal balls 445 clamp the fabric surface and use the lateral clamping friction they provide to expand the fabric edge outward when displacing outward. At the same time, the universal balls 445 use the characteristic of free rolling without direction to allow the clamped fabric to smoothly slide forward under the longitudinal winding pull, eliminating longitudinal movement friction.

[0032] To provide vertical elastic cushioning during the downward transmission process, refer to Figures 4 to 7 As shown, the trigger unit 45 includes a horizontal slot box 451, a sliding block 452, and a trigger rod 453. The horizontal slot box 451 is horizontally arranged and perpendicular to the contact frame 443. The sliding block 452 is slidably arranged on the horizontal slot box 451. The trigger rod 453 is vertically fixed on the sliding block 452. The trigger rod 453 is composed of nested inner and outer sleeve rods, which are connected by a connecting spring (not shown in the figure).

[0033] During the compression deformation and elastic recovery stroke, when the trigger rod 453 is pressed vertically downward by the guide unit 48, the inner and outer sleeve rods overcome the resistance of the connecting spring to generate axial relative contraction and sliding. After the external force is removed, they automatically recover and extend by relying on the reverse elastic restoring force of the connecting spring. Thus, the trigger rod 453 maintains the elastic extension and contraction stroke in the vertical direction during the horizontal reciprocating motion, so as to flexibly transmit the compression driving force in the vertical direction.

[0034] To provide constraint guidance for the trigger lever 453 to control the two movable clamps 442 to move closer or further apart, refer to Figures 7-8 As shown, the guide unit 48 includes a track plate 481. The number of track plates 481 is set according to the number of movable clamps 442 and is fixed on the mounting unit by a bracket. The track plate 481 has a first slide groove 482, a second slide groove 484 and a third slide groove 485 that are connected end to end and sequentially connected.

[0035] The first chute 482 has a gradually rising slope at its bottom, and its end has a horizontal section with a horizontal bottom and a width that matches the diameter of the trigger rod 453. The second chute 484 is connected to the end of this horizontal section. A first step 483 is provided at the junction of the first chute 482 and the second chute 484. The second chute 484 has a holding section with a horizontal bottom near the end that is connected to the first chute 482. The third chute 485 is connected to the end of the second chute 484. Its bottom is inclined downwards. The end of the third chute 485 is connected to the beginning of the first chute 482, and there is a second step (not shown in the figure) at the connection between the two.

[0036] As the horizontal drive unit 47 drives the C-shaped contact clip 441 to move horizontally toward the side of the fabric, the trigger rod 453 slides along the gradually rising bottom of the first slide groove 482 and is gradually pressed downward by the bottom of the groove. The trigger rod 453 moves downward and presses down on the contact frame 443, overcoming the resistance of the support spring 444 and causing the two movable clamping plates 442 to move closer to each other. When it moves to the end of the first slide groove 482, the trigger rod 453 slides into the horizontal section and is limited to the downward pressing position to keep the two movable clamping plates 442 closed together and clamping the side of the fabric. Next, the C-shaped contact clamp 441 begins to move outward in the opposite direction. The trigger rod 453 crosses the first step 483 and falls into the holding section at the beginning of the second slide groove 484. When the trigger rod 453 slides in the holding section, since the bottom of the groove is flat, the trigger rod 453 maintains a constant downward displacement to maintain the clamping state of the movable clamp plate 442 on the edge of the fabric. It also expands and stretches as the entire mechanism moves outward. When the lateral expansion reaches the outermost stretch limit endpoint, the trigger rod 453 slides into the third slide groove 485 and slides along the downwardly inclined bottom of the groove. By gradually reducing the vertical pressing force on the movable clamp plate 442 by the gradual decrease in the height of the bottom of the groove, the movable clamp plate 442 automatically opens and resets under the drive of the support spring 444 and releases the fabric to complete the unloading. Finally, the trigger rod 453 of the return motion slides to the end of the third slide 485 and returns to the initial low point position of the first slide 482. Utilizing the height difference of the second step at the connection between the two slides, the trigger rod 453 can only slide unidirectionally along the first slide 482 when entering the next action cycle. During this process, the upper end of the trigger rod 453 slides relative to the horizontal slot box 451 with the help of the sliding block 452 to provide lateral displacement compensation, ensuring that the trigger rod 453 adapts to the lateral position span change of the slide trajectory.

[0037] To eliminate fabric bouncing caused by winding tension, refer to Figures 3-4 As shown, the limiting component 5 includes two mounting side frames 51 and two constraint rollers 52. The two mounting side frames 51 are symmetrical and respectively fixed to the side of the mounting shell 42 of the corresponding flattening and expanding component 4. The two constraint rollers 52 are horizontally arranged between the two mounting side frames 51 and are arranged vertically parallel. During the limiting and anti-floating process, the forward-moving fabric passes horizontally through the straight gap reserved between the two constraint rollers 52. The two constraint rollers 52 are used to limit the up-and-down jumping of the fabric caused by the subsequent winding tension, so that the fabric is output in a stable posture.

[0038] To achieve automatic fabric unloading and stacking through reciprocating folding and stacking at the fabric infeed end, refer to... Figures 1-2 As shown, a swing assembly 1 is provided on one side of the winding frame 2. The swing assembly 1 includes a fixed frame 11, a top crossbeam 12, a drive cylinder 13, a swing arm 14, and a swing guide roller 15. The top crossbeam 12 is located on the top of the fixed frame 11, and a clearance groove for the swing arm 14 to swing is provided on the top crossbeam 12. Two drive cylinders 13 are symmetrically arranged, and one end of each is hinged to the top crossbeam 12. The swing arm 14 is vertically rotatably mounted on the top crossbeam 12 and connected to the drive cylinder 13. Two swing guide rollers 15 are arranged vertically, and both are movably mounted between the two swing arms 14.

[0039] During the fabric stacking and palletizing operation, two drive cylinders 13 reciprocate by extending and retracting, pushing and pulling two swing arms 14 around their pivot points on the top beam 12 to perform reciprocating fan-shaped swaying motions in the clearance groove, thereby causing the fabric sandwiched between the two swing guide rollers 15 to swing synchronously, completing the folding and stacking of the fabric below.

[0040] The specific workflow is as follows: During processing, the fabric to be processed is passed sequentially between the spread guide roller 15 of the spread assembly 1, the constraint roller 52 of the restriction assembly 5, the guide roller group 23, and the two movable clamps 442 in the flattening and spreading assembly 4 that are in the default open state, and finally fixedly connected to the take-up shaft of the take-up assembly 3 to complete the initial preparation.

[0041] When the fabric after stretching and setting is conveyed to the next stage, it passes between the two constraint rollers 52 of the limiting component 5. The straight gap reserved between the two rollers limits the up-and-down jumping of the fabric caused by the subsequent high tension, ensuring that the fabric is output in a relatively stable state.

[0042] During the subsequent continuous forward conveying of the fabric, the drive motor 472 of the horizontal drive unit 47 drives the eccentric cam 473 to rotate. In conjunction with the tension spring 448 of the reset unit, the C-shaped contact clamp 441 is periodically pushed and pulled to perform high-frequency horizontal reciprocating linear displacement along the slide rail 446. In a single reciprocating cycle, the trigger rod 453 first slides along the ramp section of the first slide groove 482. Its downward transmission and pressing down on the contact frame 443 cause the movable clamping plate 442 to close. The universal ball 445 clamps the edge of the fabric from the upper and lower sides. Then, the trigger rod 453 crosses the first step 483 and falls into the holding section of the second slide groove 484. While maintaining a constant clamping force, it moves laterally outward with the C-shaped contact clamp 441, expanding and stretching the edge of the fabric outward. During this process, the non-directional rolling characteristics of the omnidirectional ball 445 allow the fabric to overcome resistance and move forward smoothly. When the lateral expansion reaches the outer limit point, the C-shaped contact clamp 441 is pulled inward by the tension spring 448, and the trigger rod 453 slides into the downward section of the third slide groove 485. The pressing pressure is gradually released, and the movable clamp 442 opens to relieve the force and release the fabric under the action of the support spring 444. The trigger rod 453 finally slides back to the starting end of the first slide groove 482, closing the single flattening cycle. This action is continuously performed as the fabric is conveyed, eliminating fabric curling and wrinkles.

[0043] Subsequently, the flat fabric, supported and guided by multiple points by the guide roller group 23, enters the take-up assembly 3. The take-up shaft is driven by an external drive source to continuously wind and take up the fabric under constant tension. At the same time, for the fabric dropping process at the feeding end, the two drive cylinders 13 in the swing assembly 1 alternately extend and retract under the control of the air circuit, pushing and pulling the two swing arms 14 to reciprocate in a fan-shaped swing in the relief groove, causing the fabric passing between the swing guide rollers 15 to swing back and forth synchronously, thereby realizing the automated folding and stacking of the fabric, and completing the automated flattening, conveying and taking up of the fabric.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
