Abstract
Description
Technical Field
[0001] This application relates to the field of fabric processing technology, and in particular to a fabric folding and winding device. Background Technology
[0002] In the industrial production process of fabrics, folding and rolling are key processes that connect production, storage and transportation. The purpose of folding and rolling is to effectively avoid stretching deformation, contamination and burr wear during fabric turnover to ensure product quality. Rolling operations reduce fabric volume, reduce storage space occupancy, and avoid wrinkles during transportation to optimize storage and transportation efficiency. At the same time, it allows end users such as garment factories and home textile companies to directly obtain neat fabrics to reduce pre-processing time and thus improve the user experience.
[0003] In related technologies, fabric folding and winding mainly consists of a winding mechanism and a folding mechanism. The winding mechanism generates a continuous traction force on the fabric, allowing the fabric to be fed towards the folding mechanism at a constant speed. The core component of the folding mechanism is an isosceles triangular support. The vertex of the support faces the fabric feeding direction, and the two waist surfaces are symmetrically inclined. After the fabric contacts the waist surfaces of the support under the traction force, it will naturally fold towards the central axis of the fabric length along the inclined angle of the waist surfaces, forming a V-shaped initial crease. Subsequently, the fabric after the V-shaped fold is rolled by the winding mechanism to complete the crease shaping and winding, finally forming a regular double-layer or multi-layer folded structure.
[0004] However, this solution has certain limitations in terms of adaptability. When dealing with fabrics with irregular edges, the fit between the fabric edge and the waist of the support is uneven, which can lead to irregularities such as wrinkles and stacking on the fabric end face after folding. Such irregular folded end faces can easily cause the roll to loosen after winding, affecting transportation and the user's experience. Utility Model Content
[0005] To address the aforementioned problems, this application provides a fabric folding and winding device.
[0006] The fabric folding and winding device provided in this application adopts the following technical solution: A fabric folding and winding device includes a frame, a folding mechanism and a winding mechanism mounted on the frame, and at least one edge-gathering auxiliary component. The horizontal height of the input end of the folding mechanism is lower than the folding point height. The edge-gathering auxiliary component includes a support unit and a guide for guiding the fabric edge. The guide extends above the folded surface formed by the folding mechanism folding the fabric, and the horizontal height of the input end of the guide is lower than the horizontal height of the output end.
[0007] By adopting the above technical solution, the horizontal height of the input end of the guide is lower than the horizontal height of the output end, and the guide extends to the top of the folding surface formed by the folding mechanism. This can guide the irregular parts of the fabric edge into the folding surface and fold them into the fabric, reducing the problem of folded end face wrinkles and stacking, improving the regularity of the folding end face, thereby reducing the probability of the roll loosening after winding and ensuring the stability of the roll during transportation.
[0008] Preferably, the support unit includes a base frame, a first support rod, a second support rod, and a connecting rod. The height of the first support rod is lower than the height of the second support rod. The first support rod is disposed at the output end of the guide member. The two ends of the connecting rod are respectively fixedly connected to the first support rod and the second support rod. The two ends of the guide member are respectively fixedly connected to the two ends of the connecting rod.
[0009] By adopting the above technical solution, the height of the first support rod is lower than that of the second support rod, and the first support rod is correspondingly set at the output end of the guide, while the second support rod corresponds to the input end of the guide. The two ends of the connecting rod are fixedly connected to the first support rod and the second support rod, respectively, and the guide is fixed to both ends of the connecting rod. This structure allows the guide to naturally form an inclined state with a low input end and a high output end. When the fabric enters the folding process, the edge of the fabric is naturally lifted by the folding mechanism. The inclined guide can guide the irregular part of the fabric edge to move along a path from low to high. Under the inclined guidance of the guide, the irregular part of the fabric edge can transition from a low position to a high position and enter the folded surface formed by the folding mechanism, ensuring that the irregular part of the surface edge is stably stored inside the fabric.
[0010] Preferably, the guide includes a first extension rod, a second extension rod, and a guide rod. The length of the first extension rod is less than the length of the second extension rod. One end of the first extension rod is fixedly connected to the end of the connecting rod near the first support rod. One end of the second extension rod is fixedly connected to the end of the connecting rod near the second support rod. The two ends of the guide rod are respectively fixedly connected to the ends of the first extension rod and the second extension rod away from the connecting rod.
[0011] By adopting the above technical solution, one end of the first extension rod is fixed to the end of the connecting rod near the first support rod, and one end of the second extension rod is fixed to the end of the connecting rod near the second support rod. The length of the first extension rod is shorter than that of the second extension rod. When the two ends of the guide rod are respectively connected to the ends of the two extension rods away from the connecting rod, this length difference causes the guide rod to naturally form an inclined extension state with the side closer to the second extension rod being closer to the folding surface and the side closer to the first extension rod being relatively outward. That is, the length direction of the guide rod extends gradually into the folding surface along with the first and second extension rods. When the fabric enters the folding process and gradually moves towards the center of the fabric, the guide rod, which is in an inward extending state, can continuously conform to the irregular movement trajectory of the fabric edge, guiding the irregular part of the fabric edge to gradually transition from the outside of the fabric to the inside of the folding surface along the direction of the guide rod extending into the folding surface, ensuring that the irregular part of the fabric edge is completely included in the folding range.
[0012] Preferably, the folding mechanism includes a first folding component and a second folding component, both of which are mounted on the frame. After the fabric passes through the guide member and is guided by the guide, it enters the first folding component and the second folding component in sequence for folding.
[0013] By adopting the above technical solution, the fabric is first guided and collected by the guide component to complete the irregular edge part, which has a preliminary foundation for regularity. Then it enters the first folding component. The first folding component can first fold the fabric and complete the first edge folding of the fabric according to the preset trajectory. Then the fabric enters the second folding component. On the basis of the first folding, the second folding component further folds the fabric a second time, first solving the problem of irregular edge, and then gradually improving the overall shape through two folds, so that the fabric finally forms a flat and regular folded shape.
[0014] Preferably, the first folding assembly includes a folding auxiliary component and two folding rods. Both the two folding rods and the folding auxiliary component are mounted on the frame. The two folding rods intersect to form an intersection point. The folding auxiliary component is disposed below the intersection point and is close to the guide component.
[0015] By adopting the above technical solution, two folding rods are installed on the frame and intersect to form an intersection point. A folding auxiliary component is positioned below the intersection point and close to the guide component. When the fabric enters the first folding assembly after being guided by the guide component, the folding auxiliary component first applies a stable downward pressure to the fabric, holding it along a preset path to ensure uniform overall fabric tension and provide a stable foundation for subsequent precise folding. Simultaneously, the folding auxiliary component contacts both ends of the fabric, forming initial folding points. Subsequently, under traction, the fabric moves towards the lower end where the two folding rods intersect. Further, the fabric... The two ends of the fabric continuously abut against the edge of the folding rod. Under the combined action of the abutment force and traction, the two ends of the fabric naturally fold inward along the initial fold point to form a triangular fold surface, completing the first neat fold of the fabric. In addition, the height and slope of the guide are preset in the corresponding positions according to this folding process. From the folding auxiliary to press the fabric and stabilize the tension, to the two ends of the fabric contacting the folding rod to form a fold point, and then to the edge of the fabric folding inward along the fold point when it moves to the lower end of the cross, the guide is always adapted to this process to ensure that the remaining edge of the fabric after being processed by the guide can smoothly connect to the first folding action.
[0016] Preferably, the folding auxiliary component includes a support frame and a pressure roller. One end of the support frame is fixedly connected to the machine frame, and the other end of the support frame is fixedly connected to the pressure roller. The side of the pressure roller away from the support frame and both ends of the pressure roller abut against the fabric. The length of the pressure roller is less than the length of the fabric.
[0017] By adopting the above technical solution, one end of the support frame is fixed to the machine frame, which can provide stable support for the pressure roller and ensure that the pressure roller is always in the preset position that adapts to the folding of the fabric. The side of the pressure roller away from the support frame directly abuts the fabric. On the one hand, it can form appropriate pressure on the fabric passing by and effectively control the fabric tension. On the other hand, the length of the pressure roller is less than the length of the fabric. The two ends of the pressure roller abut with the fabric to form the initial folding point. Then, the fabric moves towards the lower end of the intersection of the two folding rods under the traction. During this process, the edges of the two ends of the fabric continue to abut with the edges of the folding rods. Under the combined action of the abutment force and the traction, the edges of the two ends of the fabric naturally fold inward according to the initial folding point to form a triangular folding surface, completing the first regular folding of the fabric.
[0018] Preferably, the first folding assembly further includes a first auxiliary displacement unit, which is disposed at both ends of the two folding rods. The first auxiliary displacement unit includes a support rod and a sliding block, wherein the sliding block is slidably disposed on the support rod, and both ends of the two folding rods are connected to the sliding block.
[0019] By adopting the above technical solution, the sliding block is slidably set on the frame, and the two ends of the two folding rods are connected to the sliding block. When the sliding block slides along the frame, it can drive the two ends of the folding rods to move synchronously, thereby flexibly adjusting the intersection angle of the two folding rods. This can specifically adapt to the length of the irregular part of the fabric edge. When the irregular part of the fabric edge is long, the intersection angle of the folding rods can be increased by sliding, which can directly widen the range of the formed triangular folding surface, reserving more sufficient space for the longer irregular edge. At the same time, the edge-gathering auxiliary component will move synchronously to the corresponding position with the adjustment of the folding rod angle, ensuring that the guide is always accurately aligned with the enlarged folding surface. At this time, when the guide guides the longer irregular edge part, because the folding surface space is more spacious, the irregular part of the fabric can be more smoothly adjusted into the folding surface along the guide path.
[0020] Preferably, the first auxiliary displacement unit further includes a driving member, which is disposed on the support rod and drives the sliding block to slide on the support rod.
[0021] By adopting the above technical solution, the driving component acts directly on the sliding block, which can drive the sliding block to slide stably along the bearing rod. The sliding block is connected to both ends of the two folding rods. The sliding of the sliding block will synchronously drive the two ends of the folding rods to move, thereby quickly adjusting the intersection angle of the two folding rods.
[0022] Preferably, the second folding assembly includes a folding guide bracket and two folding rollers, the two folding rollers being arranged in parallel and mounted on the frame, and the fabric being pulled between the two folding rollers by the folding guide bracket for folding.
[0023] By adopting the above technical solution, after the fabric is folded for the first time by the first folding component, most of the irregular edges have been contained. However, due to the fluctuation of fabric tension, some irregular edges may still have a slight risk of being exposed. At this time, the folding guide bracket will pull the fabric after the first fold along a preset trajectory, so that the fabric will form a stable folding trend again before entering the folding roller, ensuring that the edges of the fabric converge toward the center after the first fold. Subsequently, the fabric is pulled between two parallel folding rollers. The two folding rollers form a clamping force through relative rotation, firmly clamping the fabric after the first fold and completing the second fold. During the clamping process, the slightly exposed irregular edges can be completely pressed into the folding surface, further improving the tightness and regularity of the fabric fold.
[0024] Preferably, the winding mechanism includes a tension roller, a winding roller, and a plurality of finishing rollers. The tension roller, each of the finishing rollers, and the winding roller are all mounted on the frame, and the tension roller is located at the lower end of the two folding rollers.
[0025] By adopting the above technical solution, after the fabric is folded twice by the second folding component, it first enters the tension roller set at the lower end of the folding roller. The tension roller can adjust the tension of the fabric in real time to ensure that the fabric after the second folding is in a flat and stable state before entering the subsequent stages. Then the fabric passes through several sorting rollers in sequence. The sorting rollers can further correct the minor wrinkles that may be generated during the transmission of the fabric and calibrate the fabric shape to the optimal winding state. Finally, it is conveyed to the winding roller. Based on the stable fabric state, the winding roller can tightly and evenly wind the fabric into a roll.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The horizontal height of the input end of the folding mechanism is lower than the height of the folding point. The horizontal height of the input end of the guide in the edge-gathering auxiliary component is lower than the output end. The guide extends to the top of the folding surface formed by the folding mechanism. The guide can accurately guide the irregular parts of the fabric edge into the folding surface and fold them into the fabric. This effectively reduces the problem of folded end face stacking, significantly improves the regularity of the folding end face, and reduces the probability of the roll loosening after winding. This provides a reliable guarantee for the stability of the roll during transportation and fully realizes the goal of regularization and stabilization of fabric folding and winding. 2. When the fabric enters the folding process, the edge of the fabric is naturally lifted by the folding mechanism. The inclined guide can guide the irregular part of the fabric edge to move along the path from low to high. With the help of the raised edge of the fabric, these irregular parts can smoothly transition from the low position to the high position and finally enter the folding surface formed by the folding mechanism, ensuring that the irregular part of the fabric edge is stably stored inside the fabric. 3. One end of the first extension rod is fixed to the end of the connecting rod near the first support rod, and one end of the second extension rod is fixed to the end of the connecting rod near the second support rod. The length of the first extension rod is shorter than that of the second extension rod. When the two ends of the guide rod are connected to the ends of the first and second extension rods away from the connecting rod, this length difference causes the guide rod to naturally form an inclined extension state. The side closer to the second extension rod is closer to the folding surface, and the side closer to the first extension rod is relatively outward. The length direction of the guide rod gradually extends inward toward the folding surface. When the fabric enters the folding process and moves toward the center, the guide rod, which is in an inward extending state, can continuously conform to the movement trajectory of the fabric edge, guiding the irregular parts of the edge to gradually transition from the outside of the fabric to the inside of the folding surface along the direction of the guide rod extending inward toward the folding surface, ensuring that these irregular parts are completely included in the folding range.

[0036] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0037] This application discloses a fabric folding and winding device. (Refer to...) Figure 1 and Figure 2A fabric folding and rolling device is used in the field of agricultural production. With the development of agricultural modernization, the demand for agricultural coverings is increasing. Agricultural fabrics and mulch films play an important role in agricultural planting, such as maintaining soil moisture and inhibiting weed growth. By splicing fabrics to form large-size coverings, the needs of large-area agricultural coverings can be better met. This is of great significance for improving agricultural production efficiency and protecting the crop growth environment. In this embodiment, the waist ropes at both ends of the fabric are stored. The waist ropes are a key structure to ensure the stable use of the covering and improve the agricultural application effect. Agricultural coverings need to be laid in the field for a long time. The waist ropes can firmly tie the two ends of the covering to the ground anchor points, effectively resisting natural external forces such as strong winds and rainstorms, reducing the covering from being blown over, curled at the edges or shifted as a whole, and ensuring continuous coverage and protection of crop roots and soil.
[0038] Reference Figure 3 Furthermore, this embodiment includes a frame 1, a folding mechanism and a winding mechanism mounted on the frame 1, and two edge-gathering auxiliary components 4. The two edge-gathering auxiliary components 4 are located at both ends of the fabric. The horizontal height of the input end of the folding mechanism is lower than the height of the folding point. Each edge-gathering auxiliary component 4 includes a guide 41 and a support unit 42. The guide 41 is fixedly connected to the support unit 42, and the guide 41 extends above the folding surface formed by the folding mechanism folding the fabric. The horizontal height of the input end of the guide 41 is lower than the horizontal height of the output end. This design can specifically guide the waist ropes at both ends of the agricultural covering fabric to the inside of the folding surface, so that the waist ropes are stored inside the fabric. This makes the overall folding of the fabric more regular and reduces irregular phenomena such as wrinkles and bulges on the folded end of the fabric after final folding due to the waist ropes not being stored inside the fabric. This reduces the probability of the roll becoming loose after winding, improves transportation stability and the user's experience in subsequent unfolding and use.
[0039] Specifically, the support unit 42 includes a base frame 421, a first support rod 422, a second support rod 423, and a connecting rod 424. The base frame 421 provides stable support for the entire support unit 42. The first support rod 422 and the second support rod 423 are the main support components, both of which are square column-shaped rods. The height of the first support rod 422 is lower than the height of the second support rod 423. The first support rod 422 is correspondingly set at the output end of the guide member 41, and the second support rod 423 is correspondingly set at the input end of the guide member 41. The two ends of the connecting rod 424 are fixedly connected to the first support rod 422 and the second support rod 423 respectively, thus constructing a stable support frame.
[0040] Furthermore, the guide member 41 includes a first extension rod 411, a second extension rod 412, and a guide rod 413. The length of the first extension rod 411 is less than the length of the second extension rod 412. One end of the first extension rod 411 is fixedly connected to the end of the connecting rod 424 near the first support rod 422. One end of the second extension rod 412 is fixedly connected to the end of the connecting rod 424 near the second support rod 423. The two ends of the guide rod 413 are respectively fixedly connected to the ends of the first extension rod 411 and the second extension rod 412 away from the connecting rod 424.
[0041] This explains that, based on the height difference between the first support rod 422 and the second support rod 423, and the layout of the first support rod 422 and the second support rod 423 corresponding to the output and input ends of the guide member 41 respectively, and with the fixed connection between the connecting rod 424 and the guide member 41, the guide member 41 naturally forms an inclined state with the input end of the guide member 41 being low and the output end being high. At the same time, since the length of the first extension rod 411 is shorter than that of the second extension rod 412, when the guide rod 413 connects the ends of the first extension rod 411 and the second extension rod 412 away from the connecting rod 424, the guide rod 413 will exhibit an inclined extension state with the side closer to the second extension rod 412 being closer to the folding surface and the side closer to the first extension rod 411 being relatively outward. Moreover, while the guide rod 413 is inclined, the whole extends from low to high and gradually into the folding surface according to the difference in the length of the extension rod, which is just right to meet the guiding needs of the waist rope.
[0042] Furthermore, when the agricultural covering fabric enters the folding process, the waist cords at both ends of the fabric move together with the main body of the fabric, and the edges of the fabric, along with the waist cords, are naturally lifted by the folding mechanism and folded towards the center of the fabric. At this time, because the edges of the fabric are naturally lifted by the folding mechanism, the guide 41, which is in an inclined extension state, will conform to the movement trajectory of the waist cord, guiding the waist cord to move along a path from low to high, so that the waist cord smoothly transitions from a low position to a high position. At the same time, as the edges of the fabric fold towards the center of the fabric, with the help of the guide rod 413 extending into the folding surface, the waist cord is continuously guided from the outside of the fabric to the inside of the folding surface, ensuring that the irregular part of the fabric edge, the waist cord, is completely included in the folding range and finally stably stored inside the fabric, reducing the exposure of the waist cord during subsequent rolling or use, which could lead to loosening of the roll or inconvenience in unfolding.
[0043] Furthermore, the folding mechanism includes a first folding component and a second folding component 3. Both the first folding component and the second folding component 3 are mounted on the frame 1. After the fabric is guided by the guide 41, it enters the first folding component and the second folding component 3 in sequence for folding.
[0044] Reference Figure 4Specifically, the first folding assembly includes a folding auxiliary component 21 and two folding rods 22. Both the two folding rods 22 and the folding auxiliary component 21 are mounted on the frame 1. The two folding rods 22 intersect to form an intersection point. The folding auxiliary component 21 is located below the intersection point and is close to the guide component 41. The folding auxiliary component 21 includes a support frame 211 and a pressure roller 212. One end of the support frame 211 is fixedly connected to the frame 1, and the other end of the support frame 211 is fixedly connected to the pressure roller 212. The side of the pressure roller 212 away from the support frame 211 abuts against the fabric.
[0045] This explains that the two folding rods 22 are installed on the frame 1 and intersect to form an intersection point. The folding auxiliary component 21 is set below the intersection point and close to the guide component 41. The height and slope of the guide component 41 are preset to the corresponding positions according to the folding process to ensure smooth connection between the fabric edge guidance and the first fold. Since the length of the pressure roller 212 is less than the length of the fabric, when the fabric passes through the folding auxiliary component 21, the two ends of the pressure roller 212 abut against the fabric to form the initial fold point. At the same time, the side of the pressure roller 212 away from the support frame 211 provides appropriate pressure to control the fabric tension. After the fabric completes the edge guidance through the guide component 41, the folding auxiliary component 21 presses the fabric down stably to ensure uniform overall tension. Then, under the traction, the fabric moves towards the lower end of the intersection of the folding rods 22. The two ends of the fabric continue to abut against the edges of the folding rods 22. Under the combined action of the abutment force and traction, the fabric folds inward at the initial fold point to form a triangular fold surface, completing the first regular edge fold of the fabric.
[0046] Reference Figure 5 and Figure 6 Meanwhile, the first folding assembly also includes a first auxiliary displacement unit, which is disposed at both ends of the two folding rods 22. The first auxiliary displacement unit includes a support rod 231, a sliding block 232, and a driving component 233. The sliding block 232 is provided with a plug hole 2321, which is plugged into the two folding rods 22. A slide rail 2335 is fixedly disposed on the support rod 231. The driving component 233 includes a handwheel 2331, a screw 2332, a sliding seat 2333, and a connecting block 2334. The handwheel 2331 is coaxially fixed with the screw 2332. The screw 2332 is threadedly engaged with the connecting block 2334. The connecting block 2334 is fixedly disposed on the sliding seat 2333. The sliding block 232 and the connecting block 2334 are fixedly connected. The sliding seat 2333 is slidably disposed on the slide rail 2335.
[0047] This explains that when the handwheel 2331 is rotated, the screw 2332, which is coaxially fixed with the handwheel 2331, rotates synchronously. Since the screw 2332 and the connecting block 2334 have a threaded fit structure, the rotational motion of the screw 2332 can be converted into the linear displacement of the connecting block 2334. The connecting block 2334 is fixedly connected to the sliding seat 2333 on one hand and to the sliding block 232 on the other. Therefore, the displacement of the connecting block 2334 will synchronously drive the sliding seat 2333 to slide stably along the slide rail 2335 on the bearing rod 231, and at the same time drive the sliding block 232 to slide along the frame 1. Since the first auxiliary displacement unit is correspondingly set at both ends of the two folding rods 22, and the sliding block 232 is plugged into the folding rod 22 through the insertion hole 2321, the sliding of the sliding block 232 will form a push-pull force on the end of the folding rod 22, and finally realize the flexible adjustment of the intersection angle of the two folding rods 22.
[0048] Furthermore, the flexible adjustment of the intersection angle of the two folding rods 22 can be specifically adapted to the length of the irregular part of the fabric edge. When the irregular part of the fabric edge is long, the intersection angle of the folding rods 22 can be increased by sliding, which can directly widen the range of the triangular folding surface and reserve more sufficient space for the longer irregular edge. At the same time, the edge-gathering auxiliary component 4 will move synchronously to the corresponding position as the angle of the folding rods 22 is adjusted, ensuring that the guide 41 is always accurately aligned with the enlarged folding surface. At this time, when the guide 41 guides the longer irregular edge, the irregular part of the fabric can be more smoothly adjusted into the folding surface along the guide path because the folding surface space is more spacious.
[0049] Reference Figure 7 Furthermore, the second folding assembly 3 includes a folding guide bracket 31 and two folding rollers 32. The folding guide bracket 31 is mounted on the frame 1 and is an isosceles triangular bracket. The base of the isosceles triangular bracket is fixed to the top of the frame 1 and is located at the upper end of the intersection of the two folding rods 22. The two folding rollers 32 are arranged in parallel and are rotatably supported on the frame 1. The vertex of the isosceles triangular bracket is located above the two folding rollers 32 and between the two folding rollers 32.
[0050] This explains that after the fabric is folded for the first time, when the fabric is pulled to the folding guide bracket 31, the base of the isosceles triangle bracket first provides stable support for the fabric. Since the width of the isosceles triangle bracket gradually decreases from the base to the vertex, the fabric will naturally and evenly gather towards the middle along the hypotenuses on both sides of the isosceles triangle bracket as it moves forward with the conveyor. At the same time, the vertex of the isosceles triangle bracket is located above the two parallel folding rollers 32 and directly opposite the channel between the two folding rollers 32. This layout can accurately guide the gathered fabric to smoothly enter the channel between the two folding rollers 32 when it reaches directly below the vertex. Finally, through the synchronous clamping action of the two folding rollers 32, the second folding of the fabric is stably completed.
[0051] Furthermore, after the fabric is folded for the first time by the first folding component, although most of the irregular edges have been contained, some irregular edges may still be slightly exposed due to fluctuations in fabric tension. At this time, the folding guide bracket 31 pulls the fabric after the first fold along a preset trajectory, so that the fabric forms a stable folding trend again before entering the folding roller 32, ensuring that the edges of the fabric converge toward the center after the first fold. Subsequently, the fabric is pulled between two parallel folding rollers 32. The two folding rollers 32 form a clamping force through relative rotation, firmly clamping the fabric after the first fold and completing the second fold. During the clamping process, the slightly exposed irregular edges can be completely pressed into the folding surface, further improving the tightness and regularity of the fabric fold.
[0052] On the other hand, the winding mechanism includes a tension roller 5, a winding roller 6, and several finishing rollers 7. The tension roller 5, each finishing roller 7, and the winding roller 6 are all mounted on the frame 1. The several finishing rollers 7 are mounted between the tension roller 5 and the winding roller 6. The tension roller 5 is mounted at the lower end of the two folding rollers 32.
[0053] Reference Figure 8 Meanwhile, the winding mechanism also includes a second auxiliary displacement unit 8, which includes a vertical plate 81, a bearing seat 82, and a drive cylinder 83. There are two vertical plates 81 and two bearing seats 82. The two vertical plates 81 and two bearing seats 82 are located at both ends of the tension roller 5. The upper and lower ends of the vertical plate 81 are fixedly connected to the frame 1. The vertical plate 81 is provided with a sliding groove 811. The two ends of the tension roller 5 are rotatably supported on the bearing seats 82. The bearing seats 82 are slidably located in the sliding groove 811. The drive cylinder 83 is fixedly connected to the bearing seat 82. The piston rod of the drive cylinder 83 is fixed on the frame 1.
[0054] This explains that after the fabric is folded twice, the winding process begins. First, it passes through the tension roller 5. When the piston rod of the drive cylinder 83 extends and retracts, it directly drives the bearing seat 82, which is fixed to it, to slide stably along the sliding groove 811 of the vertical plate 81. Since the two ends of the tension roller 5 are supported by the bearing seat 82 due to rotation, the sliding of the bearing seat 82 will synchronously drive the tension roller 5 to move. When the fabric tension is too low, the drive cylinder 83 drives the tension roller 5 to move away from the finishing roller 7. When the fabric tension is too high, the drive cylinder 83 drives the tension roller 5 to move closer to the finishing roller 7.
[0055] Furthermore, the tension roller 5 ensures that the fabric after the second folding is in a flat and stable state before entering the subsequent stages. The fabric then passes through several finishing rollers 7 in sequence. The finishing rollers 7 can further correct the minor wrinkles that may be generated during the transmission of the fabric and calibrate the fabric shape to the optimal winding state. Finally, it is conveyed to the winding roller 6. Based on the stable fabric state, the winding roller 6 can tightly and evenly wind the fabric into a roll.
[0056] The implementation principle of the fabric folding and winding device in this application embodiment is as follows: After the agricultural mulch fabric enters the device, it first contacts the edge-gathering auxiliary component 4. In the support unit 42, the base frame 421 provides stable support. The first support rod 422 corresponds to the output end of the guide 41 and is relatively low in height. The second support rod 423 corresponds to the input end of the guide 41 and is relatively high in height. The first support rod 422 and the second support rod 423 jointly construct the support frame through the connecting rod 424. At the same time, the first extension rod 411 of the guide 41 is shorter and the second extension rod 412 is longer. Due to the height difference between the first support rod 422 and the second support rod 423, as well as the length difference between the first extension rod 411 and the second extension rod 412, the guide 41 naturally forms an inclined state. The guide rod 413 extends into the folding surface that the folding mechanism will form. The waist ropes at both ends of the fabric move together with the main body of the fabric. The inclined guide 41 conforms to the movement trajectory of the waist ropes, guiding the waist ropes to smoothly transition along a path from low to high, while continuously guiding the waist ropes from the outside of the fabric to the inside of the folding surface.
[0057] The fabric, guided by the waist cord, enters the first folding assembly. One end of the support frame 211 of the folding auxiliary component 21 is fixed to the machine frame 1, and the other end is fixed to the pressure roller 212. The side of the pressure roller 212 away from the support frame 211 abuts against the fabric, forming initial folding points with both ends of the fabric and controlling the fabric tension. Subsequently, under the traction, the fabric moves further through the two intersecting folding rods 22, with the edges of both ends of the fabric continuously abutting against the edges of the folding rods 22. Under the combined action of the abutment force and traction, the fabric folds inward at the initial folding points to form a triangular folded surface. If the irregular part of the fabric edge, the waist cord, is... Depending on the length, the handwheel 2331 of the first auxiliary displacement unit can be rotated. The handwheel 2331 drives the coaxially fixed screw 2332 to rotate. The screw 2332 and the connecting block 2334 are threaded together, so that the connecting block 2334 drives the sliding seat 2333 to slide along the slide rail 2335 on the bearing rod 231. At the same time, the connecting block 2334 drives the sliding block 232 to move. The sliding block 232 is inserted into the folding rod 22, thereby adjusting the intersection angle of the two folding rods 22. When facing a long waist rope, the intersection angle of the folding rods 22 can be increased to widen the accommodation space of the triangular folding surface. At the same time, the edge-gathering auxiliary component 4 moves synchronously.
[0058] After the initial fold, the fabric is drawn to the second folding assembly 3. The bottom edge of the folding guide bracket 31 is fixed to the top of the frame 1 and located at the upper end of the intersection of the folding rods 22. The fabric first contacts the bottom edge of the folding guide bracket 31, which provides stable support. As the width of the folding guide bracket 31 gradually decreases from the bottom edge to the apex, the fabric naturally and evenly gathers towards the center along the inclined surfaces on both sides of the bracket during the conveying process. When the fabric moves to the apex of the folding guide bracket 31, the apex is above the two parallel folding rollers 32 and directly opposite the channel between the two rollers. Guided by the apex, the fabric smoothly enters between the two rollers 32. The folding rollers 32 generate clamping force through relative rotation, firmly clamping the fabric and completing the second fold. At the same time, the waistband portion that may have been slightly exposed after the first fold is completely pressed into the folded surface, further improving the tightness and regularity of the fabric fold.
[0059] After being folded twice, the fabric enters the winding mechanism, first passing through the tension roller 5. The two vertical plates 81 of the second auxiliary displacement unit 8 are fixed to the frame 1 at their upper and lower ends. The vertical plates 81 have sliding grooves 811, and bearing seats 82 are slidably positioned within these grooves. The tension roller 5's two ends rotate and are supported on the bearing seats 82. The drive cylinder 83 is fixed to the bearing seats 82, and its piston rod is fixed to the frame 1. When the fabric tension is low, the piston rod of the drive cylinder 83 extends, causing the bearing seats 82 to move along the sliding grooves 811, thereby moving the tension roller 5 away from the finishing roller 7, increasing its tension. The fabric is stretched to increase tension. When the fabric tension is too high, the piston rod of the drive cylinder 83 shortens, causing the bearing seat 82 and tension roller 5 to move closer to the finishing roller 7, shortening the fabric stretch to reduce tension and ensuring stable fabric tension. Subsequently, the fabric passes through several finishing rollers 7 in sequence. The finishing rollers 7 correct the minor wrinkles generated by the fabric during the transmission process and calibrate the fabric shape to the optimal state for winding. After tension adjustment and wrinkle correction, the fabric is conveyed to the winding roller 6. The winding roller 6 tightly and evenly winds the fabric into a roll, thus completing the entire fabric folding and winding operation.
[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
