Abstract
Description
Technical Field
[0001] This utility model relates to the field of sling technology, and in particular to a four-roller sling winding device. Background Technology
[0002] Early processes relied on manual adjustment of tension and guidance, which resulted in loose rolls, edge misalignment, and difficulty in adapting to high-speed production. In mass production scenarios in textiles and packaging, manual intervention led to limited production capacity. A new four-roller sling winding device achieves dynamic tension balance and precise control of the winding path through a multi-roller collaborative mechanism. Compared with traditional processes, it can match high-speed production lines, significantly improves the flatness and density of the rolls, and its modular design is compatible with multiple product specifications, shortens changeover time, and adapts to the needs of flexible production. In the field of high-strength industrial strip materials, it provides technical assurance for quality stability.
[0003] A search revealed Chinese patent publication number CN220519669U, which discloses a braided tape winding device. The device includes a base, with a winding assembly and a pulling assembly respectively disposed on the upper surface of the base. The winding assembly includes a winding frame fixedly mounted on the upper surface of the base, and a winding shaft rotatably connected to the surface of the winding frame. The winding shaft has a rectangular vertical cross-section, and a winding core sleeve is fitted onto the surface of the winding shaft. A pressing assembly is disposed on the surface of the winding frame. This braided tape winding device fixes one end of the braided tape to the surface of the winding core sleeve. A winding motor drives the winding shaft to rotate, thereby rotating the winding core sleeve to wind the braided tape. Simultaneously, the pressing assembly uses a first hydraulic rod to extend and compress a support spring, driving the extension... As the retractor moves downward, the clamping roller contacts and presses against the braided strip wound on the surface of the take-up core sleeve, thereby reducing the gap inside the braided strip and the volume of the braided strip roll after winding, thus facilitating logistics and transportation. However, in actual use, the tension of the active roller in early equipment required manual adjustment and could not be dynamically adapted in real time according to the elasticity and thickness of the sling. Elastic materials would slip due to insufficient pressure between the rollers, while thick materials would be excessively stretched and deformed. The guide roller path adjustment relied on mechanical limiters, which made it difficult to accurately match the curvature of strips of different thicknesses, resulting in uneven edge stacking. In addition, there was a lack of multi-station synchronous winding capability, which required frequent shutdowns to change models when dealing with multi-specification production. In small-batch, multi-variety scenarios, there was significant waste of production capacity, which restricted the equipment's adaptability to flexible production and the process of intelligent upgrading. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a four-roller sling winding device, which aims to improve the problem that early equipment could not dynamically adapt to the elasticity and thickness of the sling in real time, making it difficult to accurately match the curvature of strips of different thicknesses, resulting in uneven edge stacking, which restricted the equipment's adaptability to flexible production and the process of intelligent upgrading.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a four-roller sling winding device, comprising a carrier box, wherein a spacing adjustment mechanism is provided on the front and rear sides of the top of the carrier box, the spacing adjustment mechanism being used to adjust the stretch of the sling, a connecting plate is fixedly connected to the left side of the carrier box, a winding adjustment mechanism is fixedly connected to the left side of the connecting plate, the winding adjustment mechanism being used to adjust the winding of the sling, a straightening mechanism is provided on the top left side of the carrier box, a limit mechanism is provided at the top left end of the carrier box, and a connecting mechanism is provided on the left side of the connecting plate; The spacing adjustment mechanism includes two mounting baffles. The bottoms of the two mounting baffles are fixedly connected to the front and rear sides of the top of the carrier box. A carrier plate is fixedly connected to the opposite side of the two mounting baffles. A motor is fixedly connected to the top of the two carrier plates. A lead screw is fixedly connected to the output end of the two motors. A mounting block is fixedly connected to the outside of the two lead screws. The same drive roller is fixedly connected between adjacent mounting blocks. A driven roller is fixedly connected to the outside of the drive roller. A guide component is provided on the right side of the spacing adjustment mechanism.
[0006] Through the above technical solution: two mounting baffles are firmly installed on the top of the carrier box as support components, providing rigid support for subsequent components. The carrier plate extends laterally to the outside of the mounting baffles. The motor is connected to the lead screw, which efficiently converts the rotational motion of the motor into linear motion. During adjustment, the motor drives the lead screw to rotate, causing the mounting block to slide along the lead screw axis. Since the two mounting blocks jointly fix the drive roller, the synchronous adjustment of the roller spacing is achieved. The driven roller is coaxially fixed with the drive roller and always remains parallel when the spacing changes, ensuring that the sling is subjected to uniform force when passing through the roller gap, and can quickly respond to the needs of slings of different thicknesses and elasticities.
[0007] As a further description of the above technical solution: The winding adjustment mechanism includes a mounting box. The right side of the mounting box is located on the left side of the connecting plate. Two drive rollers are rotatably connected to the front and rear sides of the mounting box. Limiting take-up rollers are fixedly connected between adjacent drive rollers. Rotating take-up rollers are fixedly connected to the middle of the drive rollers. Knobs are fixedly connected to the opposite sides of the drive rollers. Adjusting rollers are fixedly connected to the four corners of the bottom of the mounting box. A motor is fixedly connected to the top of the mounting box.
[0008] The above technical solution utilizes a mounting box as the main frame, with its right side fixedly connected to a connecting plate to form a stable structure. Two active rollers are installed on each of the front and rear sides, rotating flexibly via bearing seats. The spacing between adjacent rollers is defined by a limiting take-up roller, ensuring that multiple slings are wound independently without tangling. A rotating take-up roller in the middle of the active roller is fixed via a key connection and rotates synchronously with the active roller to achieve tight winding. Once the roll is full, the operator can quickly disassemble the rotating take-up roller and the limiting take-up roller by rotating the knob on the outside of the active roller. The bottom adjusting roller supports angle adjustment, eliminating the need for anchor bolts and significantly reducing debugging time. The multi-active roller independent drive mode allows for the simultaneous winding of various sling specifications, adapting to flexible production needs. Motor 3 on the top of the mounting box provides power to the winding adjustment mechanism.
[0009] As a further description of the above technical solution: The guiding assembly includes two limiting blocks. The left sides of the two limiting blocks are fixedly connected to the right ends of the two lead screws. A first guiding roller is rotatably connected between adjacent limiting blocks, and a second guiding roller is rotatably connected between adjacent bearing boxes on the right side.
[0010] Through the above technical solution: the limiting block in the guide component is fixed to the right end of the lead screw, and the guide roller cooperates with another guide roller that is fixedly installed to form a stable guide channel, ensuring that the sling is conveyed along the preset path, and the feeding angle can be kept stable even if the roller spacing is adjusted.
[0011] As a further description of the above technical solution: The straightening mechanism includes multiple rotating rollers, the front and rear ends of which are rotatably connected between two adjacent support boxes. A second motor is fixedly connected to the front left end of the front support box, and the output end of the second motor is fixedly connected to the front end of the left rotating roller.
[0012] Through the above technical solution: the straightening mechanism uses a motor as a power source, and drives the other rollers to operate synchronously through the left rotating roller to form a relay transmission chain, which disperses the transmission tension, avoids damage to the belt, and can adjust the motor speed according to the material and thickness of the sling to accurately match the winding speed.
[0013] As a further description of the above technical solution: The limiting mechanism includes a bearing rod, the front and rear ends of which are fixedly connected between two adjacent bearing boxes. Multiple limiting sliders are fixedly connected to the outside of the bearing rod, and limiting baffles are fixedly connected to the outside of each of the multiple limiting sliders.
[0014] Through the above technical solution: the bearing rod in the limiting mechanism spans the bearing box, and the fixed limiting slider and limiting baffle form a three-dimensional protection, which can adapt to different bandwidths and correct belt offset, prevent slippage and stacking, and effectively improve the reliability of the winding device and the quality of the finished product.
[0015] As a further description of the above technical solution: A guide recess is fixedly connected to the top left side of the connecting plate, and the same guide rod is fixedly connected to adjacent members on the right side of the connecting plate.
[0016] The above technical solution involves a guide plate and a guide rod forming a combined guide structure. The guide rod first positions the sling, allowing the sling to pass through the guide plate channel at a fixed angle and be precisely guided into the winding adjustment mechanism. This avoids bending or deviation during transmission and improves the stability of the winding start.
[0017] As a further description of the above technical solution: The connecting mechanism includes a grooved plate, the left end of which is fixedly connected to the bottom right side of the mounting box. Rubber connecting posts are fixedly connected to both the left and right ends of the bottom right side of the mounting box, and a protrusion plate is fixedly connected to the left side of the connecting plate.
[0018] The above technical solution uses a tenon-and-mortise joint between a grooved plate and a protruding plate in the connection mechanism, combined with the elastic buffer of the rubber connecting column, to ensure a stable connection between the mounting box and the connecting plate, absorb vibration, reduce wear, facilitate quick disassembly and assembly, and adjust the position and angle of the mounting box when switching between multiple specifications.
[0019] As a further description of the above technical solution: An electrostatic eliminator is fixedly connected to the front side of the carrier box, and a sensor is fixedly connected to the front side of the inside of the carrier box.
[0020] The above technical solution integrates an electrostatic elimination device into the carrier box, which eliminates static electricity on the surface of the sling in real time through internal sensors. This prevents dust from being attracted by static electricity, thus ensuring stable and efficient winding, and improving product qualification rate and production intelligence.
[0021] This utility model has the following beneficial effects: 1. In this utility model, the motor drives the screw to move the mounting block, thereby realizing the automatic adjustment of the distance between the drive roller and the driven roller, improving the adaptability to slings with different elasticity and thickness. It can dynamically adjust the roller distance according to material characteristics or sensor feedback, reducing the stretching breakage of the belt or the loosening of the roll, and ensuring that the tension of the drive roller can be automatically adjusted to effectively adapt to slings with different elasticity and thickness, thus promoting the equipment's adaptability to flexible production and intelligent upgrading process.
[0022] 2. In this utility model, by cooperating with multiple active rollers, limiting take-up rollers, and rotating take-up rollers, four-roller synchronous winding is achieved while taking into account flexibility, adapting to the flexible production needs of small batches and multiple varieties. After the roll is full, the take-up rollers can be quickly and manually disassembled by a knob. The bottom adjustment rollers support multi-angle adjustment, adapting to different production line layouts and improving installation convenience, ensuring winding efficiency while taking into account practicality and economy.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 , Figure 2 and Figure 4The present invention provides an embodiment of a sling four-roller winding device, comprising a carrier box 1, a spacing adjustment mechanism 2 provided on the front and rear sides of the top of the carrier box 1, the spacing adjustment mechanism 2 being used to adjust the stretch of the sling, a connecting plate 3 fixedly connected to the left side of the carrier box 1, a winding adjustment mechanism 4 fixedly connected to the left side of the connecting plate 3, the winding adjustment mechanism 4 being used to adjust the winding of the sling, a straightening mechanism 9 on the top left side of the carrier box 1 being used to provide power, a limit mechanism 5 provided at the top left end of the carrier box 1 being used to limit the conveying of the sling, and a connecting mechanism 8 on the left side of the connecting plate 3 being used to connect the two side mechanisms; The spacing adjustment mechanism 2 includes two mounting baffles 201. The bottom of the two mounting baffles 201 is fixedly connected to the front and rear sides of the top of the carrier box 1. The opposite sides of the two mounting baffles 201 are fixedly connected to the carrier plate 202. The top of the two carrier plates 202 is fixedly connected to the motor 203. The output end of the two motors 203 is fixedly connected to the lead screw 204. The outside of the two lead screws 204 is fixedly connected to the mounting block 205. The same drive roller 206 is fixedly connected between the adjacent mounting blocks 205. The driven roller 207 is fixedly connected to the outside of the drive roller 206. The motor 203 drives the lead screw 204 to move the mounting block 205, thereby realizing the automatic adjustment of the spacing between the drive roller 206 and the driven roller 207. A guide component 208 is provided on the right side of the spacing adjustment mechanism 2. Specifically, two mounting baffles 201 are securely mounted on the top of the carrier box 1 as supporting components, providing a rigid support foundation for subsequent components. The carrier plate 202 extends laterally to the outside of the mounting baffles 201. The mounted motor 203 is tightly connected to the lead screw 204 through a coupling, efficiently converting the rotational motion of the motor into linear motion. When adjustment is required, the motor 203 drives the lead screw 204 to rotate, causing the mounting block 205 to slide smoothly along the axis of the lead screw 204. Since the two mounting blocks 205 jointly fix the drive roller 206, the synchronous adjustment of the roller spacing is achieved. The driven roller 207 is coaxially fixed with the drive roller 206 and always remains parallel when the spacing changes, ensuring that the sling is subjected to uniform force when passing through the roller gap. It can quickly respond to the needs of slings of different thicknesses and elasticities, further improving the stability of the winding process and the flatness of the finished roll. It effectively solves the problems of poor adaptability and tension loss control of traditional fixed-spacing winding devices, and significantly improves the production efficiency and product quality of the equipment.
[0027] Reference Figure 1 , Figure 2 and Figure 3The winding adjustment mechanism 4 includes a mounting box 401. The right side of the mounting box 401 is located on the left side of the connecting plate 3. Two active rollers 402 are rotatably connected to the front and rear sides of the mounting box 401. Limiting take-up rollers 403 are fixedly connected between adjacent active rollers 402. Rotating take-up rollers 404 are fixedly connected to the middle of the active rollers 402. Knobs 405 are fixedly connected to the opposite sides of the active rollers 402. After winding, the take-up rollers can be manually and quickly removed by using the knobs 405. Adjusting rollers 406 are fixedly connected to the four corners at the bottom of the mounting box 401 to support multi-angle adjustment and improve installation convenience. A motor 407 is fixedly connected to the top of the mounting box 401. Specifically, the mounting box 401 serves as the main frame, and is fixedly connected to the connecting plate 3 on the right side to form a stable mechanical connection structure. Two active rollers 402 are set on each of the front and rear sides, which can rotate flexibly through bearing seats. The adjacent spacing is precisely defined by the limiting take-up roller 403 to ensure that multiple slings maintain an independent path during the winding process and avoid mutual entanglement. The rotating take-up roller 404 in the middle of the active roller 402 is fixed by a key connection and rotates synchronously with the active roller 402 to achieve tight winding of the slings. When the roll reaches the preset diameter, the operator can quickly disassemble the rotating take-up roller 404 or the limiting take-up roller 403 by rotating the knob 405 on the outside of the active roller 402. The bottom adjusting roller 406 can adjust the angle of the production line. No additional anchor bolts are required during installation, which shortens the debugging time. In addition, the independent drive mode of multiple active rollers 402 supports the simultaneous winding of multiple different specifications of slings, which is suitable for flexible production needs. The motor 407 on the top of the mounting box 401 provides power to the winding adjustment mechanism 4.
[0028] Reference Figure 1 , Figure 2 and Figure 4 The guide assembly 208 includes two limiting blocks 2081. The left sides of both limiting blocks 2081 are fixedly connected to the right ends of two lead screws 204. A guide roller 1 2082 is rotatably connected between adjacent limiting blocks 2081. A guide roller 2083 is rotatably connected between adjacent bearing boxes 1 on the right side. The sling is guided between the guide roller 1 2082 and the guide roller 2 2083. The straightening mechanism 9 includes multiple rotating rollers 901. The front and rear ends of the multiple rotating rollers 901 are rotatably connected between adjacent bearing boxes 1. The front bearing... A motor 902 is fixedly connected to the front left end of the carrier box 1. The output end of the motor 902 is fixedly connected to the front end of the left rotating roller 901. The left rotating roller 901 is driven by the motor 902 to drive the other rotating rollers 901 to move the sling. The limiting mechanism 5 includes a bearing rod 501. The front and rear ends of the bearing rod 501 are fixedly connected between the two adjacent carrier boxes 1. Multiple limiting sliders 502 are fixedly connected to the outside of the bearing rod 501. Limiting baffles 503 are fixedly connected to the outside of the multiple limiting sliders 502 to limit the sling from deviating or even falling off. Specifically, the two limiting blocks 2081 in the guide assembly 208 are fixed to the right end of the lead screw 204. The first guide roller 2082, along with the fixedly installed second guide roller 2083, forms a guide channel to ensure that the conveyor belt is always smoothly conveyed along the preset path. Even when the distance between the drive roller 206 and the driven roller 207 is adjusted, a stable feeding angle can be maintained. The straightening mechanism 9 is powered by the second motor 902, which drives the other rollers 901 to operate synchronously through the left rotating roller 901, forming a continuous transmission chain. This disperses the tension during the conveyor belt transmission process, avoiding damage to the belt due to excessive force at a single point. The transmission speed can be precisely matched by adjusting the speed of motor 902 according to the different materials and thicknesses of the slings, ensuring a stable winding rhythm. The limiting mechanism 5 provides safety protection for the sling transmission. The bearing rod 501 spans between the two bearing boxes 1. Multiple fixed limiting sliders 502 and limiting baffles 503 form a three-dimensional protective structure. The limiting baffles 503 are adapted to slings of different widths and limit the belt deviation in real time during transmission. When the sling deviates slightly, the baffle corrects the trajectory in time through physical contact, preventing the belt from slipping or stacking, thus improving the reliability of the sling winding device and the quality of the finished product.
[0029] Reference Figure 1 , Figure 2 and Figure 4 A guide concave plate 7 is fixedly connected to the top left side of the connecting plate 3. The same guide rod 10 is fixedly connected between adjacent sections on the right side of the connecting plate 3. The sling is guided through the guide rod 10 and passes through the guide concave plate 7 to enter the winding adjustment mechanism 4. The connecting mechanism 8 includes a groove plate 801. The left end of the groove plate 801 is fixedly connected to the bottom right side of the mounting box 401. Rubber connecting posts 802 are fixedly connected to both the left and right ends of the bottom right side of the mounting box 401. A protrusion plate 803 is fixedly connected to the left side of the connecting plate 3. An electrostatic elimination device 6 is fixedly connected to the front side of the bearing box 1. A sensor 11 is fixedly connected to the front inside the bearing box 1. Specifically, the guide concave plate 7 and the guide rod 10 form a combined guide structure. The guide rod 10 first positions the sling, allowing it to pass through the channel of the guide concave plate 7 at a fixed angle and be precisely guided into the winding adjustment mechanism 4. This effectively prevents the sling from bending or shifting during transmission, improving stability at the beginning of winding. The connecting mechanism 8 uses a tenon-and-mortise joint between the grooved plate 801 and the protruding plate 803, combined with the elastic buffer of the rubber connecting column 802. This ensures a stable connection between the mounting box 401 and the connecting plate 3, absorbs vibrations during equipment operation, and reduces component wear. It is not only easy to quickly disassemble and assemble, but also allows for flexible adjustment of the position and angle of the mounting box 401 when switching between multiple specifications. The static elimination device 6 integrated in the bearing box 1 can eliminate static electricity on the surface of the sling in real time through the internal sensor 11, preventing dust from being attracted by static electricity and affecting product quality. This ensures that the entire winding process is stable and efficient, effectively improving product qualification rate and production intelligence level.
[0030] Working Principle: The sling first passes through the combined guide structure consisting of guide rod 10 and guide concave plate 7, completing initial positioning and angle calibration to ensure the sling enters the device in a stable posture. The sling then passes through guide assembly 208, composed of guide roller 1 2082 and guide roller 2083. This assembly is linked with the spacing adjustment mechanism 2 to maintain a stable conveying path for the sling. Motor 1 203 drives screw 204 to rotate, causing mounting block 205 to slide horizontally, thereby synchronously adjusting the spacing between drive roller 206 and driven roller 207. When slings of different thicknesses or elasticities are detected, the system automatically adjusts the roller spacing: increasing the spacing when thick slings pass to avoid compression deformation, and decreasing the spacing when elastic slings pass to maintain sufficient friction and prevent slippage. During this process, driven roller 207 and drive roller 206 remain parallel to ensure uniform force on the sling and maintain constant tension. Straightening mechanism 9 uses motor 2 902 as its power source, driving the other rotating rollers 901 through the left rotating roller 901. The continuous operation forms a relay-type transmission chain, which not only disperses the tension of the sling transmission, but also allows for flexible adjustment of the motor speed according to the sling material and thickness, precisely matching the winding speed. At the same time, the limiting baffle 503 in the limiting mechanism 5 restricts the position of the sling. If any deviation occurs, the trajectory can be corrected through physical contact to prevent the sling from slipping or piling up. After entering the winding adjustment mechanism 4, the active roller 402 drives the rotating take-up roller 404 to rotate under the drive of the motor 407, realizing the winding of the sling. The limiting take-up roller 403 ensures that multiple slings are wound independently, avoiding mutual interference. When the roll reaches the preset diameter, the operator can quickly disassemble the rotating take-up roller 404 or the limiting take-up roller 403 by using the knob 405 to complete the roll change. The bottom adjusting roller 406 supports multi-angle adjustment, which is convenient for equipment installation, debugging and production line adaptation. The static elimination device 6 on the carrier box 1 continuously eliminates static electricity on the surface of the sling, avoiding the impact of static electricity on product quality due to the adsorption of impurities, and achieving high efficiency, precision and stability in the sling winding process.
