Description

Technical Field

[0001] This utility model relates to the field of winding devices, and in particular to a fabric tensioning and winding device. Background Technology

[0002] In the existing coil processing technology system, the complete process of coil production covers multiple precision links, from raw material pretreatment, multi-layer lamination, precision coating to the final product slitting and winding. Among them, the winding process is a key node connecting the end of production and the output of finished products. Its operating efficiency and equipment stability not only directly determine the output of finished products per unit time, but also profoundly affect the overall efficiency of the entire production line and the stability of product quality.

[0003] In existing technologies, common winding machines typically employ a single support roller design. This necessitates the replacement of the winding roller after each winding cycle. This replacement requires a series of tedious operations, resulting in prolonged machine downtime each time the winding roller is changed. During this downtime, the winding machine cannot perform any winding operations, and other related processes on the production line must also be suspended, causing interruptions in the entire production process. This not only wastes a significant amount of production time, preventing the equipment from operating continuously and efficiently and reducing equipment utilization, but also increases overall production costs due to the continuous incurrence of labor costs and equipment depreciation during downtime. Therefore, an improved fabric tensioning and winding device is needed to solve these problems. Utility Model Content

[0004] To overcome the problem that the single support roller design makes the replacement process cumbersome, time-consuming, and labor-intensive in actual use, which seriously affects the entire production process.

[0005] The technical solution of this utility model is as follows: a fabric tensioning and winding device, including a device body, a tensioning component disposed on the device body, a first motor fixedly connected to the device body, a first gear fixedly connected to the output end of the first motor, a second gear meshing with the first gear, a rotating bracket rotatably connected to the device body, a first support roller rotatably connected to the rotating bracket, a limiting component disposed on the device body, a driving component disposed on the device body, and an adjusting component disposed on the driving component. The rotating bracket is rotatably connected to the device body. When the first motor is working, it drives the first gear to rotate. When the first gear rotates, it adjusts the rotation of the rotating bracket by cooperating with the second gear.

[0006] Preferably, the main body of the device has a limiting groove at the relative position of the rotating bracket, and the rotating bracket is rotatably connected to the rotating groove.

[0007] Preferably, the drive assembly includes a first connecting seat fixedly connected to the main body of the device, a first electric push rod fixedly connected to the first connecting seat, a sliding seat slidably connected to the first connecting seat, a second motor fixedly connected to the sliding seat, a rotating shaft fixedly connected to the output end of the second motor, and a connecting bushing fixedly connected to the first support roller. The rotating shaft is movably connected to the connecting bushing, and the sliding seat is fixedly connected to one end of the first electric push rod. The first electric push rod drives the sliding seat and the second motor to move. When the rotating shaft is in contact with the connecting bushing, the second motor drives the first support roller to rotate.

[0008] Preferably, the connecting bushing has a groove, and the rotating shaft is movably connected to the groove.

[0009] Preferably, the limiting component includes a fixed ring fixedly connected to the rotating bracket, a limiting block fixedly connected to the main body of the device, and the limiting block surrounding both sides of the fixed ring.

[0010] Preferably, the adjusting assembly includes a first fixed bracket fixedly connected to a first connecting seat, a first threaded rod threadedly connected to the first fixed bracket, a first knob fixedly connected to the first threaded rod, a first sliding rod slidably connected to the first fixed bracket, a first limiting block fixedly connected to one end of the first sliding rod, a second fixed bracket fixedly connected to a rotating bracket, a second threaded rod threadedly connected to the second fixed bracket, a second knob fixedly connected to one end of the second threaded rod, a second sliding rod slidably connected to the second fixed bracket, a second limiting block fixedly connected to one end of the second sliding rod, the end of the first threaded rod away from the first knob being rotatably connected to the first limiting block, and the end of the second threaded rod away from the second knob being rotatably connected to the second limiting block. Rotation of the first knob adjusts the rotation of the first threaded rod, which in turn moves the first limiting block and the first sliding rod. Rotation of the second knob adjusts the rotation of the second threaded rod, which in turn moves the second limiting block and the second sliding rod.

[0011] Preferably, both the first and second limiting blocks have connecting grooves, the first threaded rod is rotatably connected to the groove of the first limiting block, and the second threaded rod is rotatably connected to the second limiting block.

[0012] Preferably, the tensioning assembly includes a third threaded rod rotatably connected to the main body of the device, a third knob fixedly connected to one end of the third threaded rod, a sliding block threadedly connected to the third threaded rod, a third sliding rod slidably connected to the sliding block, a first fixing block fixedly connected to one end of the third sliding rod, a first spring fixedly connected between the sliding block and the first fixing block, a connecting rod fixedly connected to the first fixing block, and a tensioning roller rotatably connected to the connecting rod. The sliding block is slidably connected to the main body of the device. Rotating the third knob drives the third threaded rod to rotate, and rotating the third threaded rod adjusts the movement of the sliding block.

[0013] The beneficial effects of this utility model are:

[0014] 1. This alternating operation mode can ensure the continuity of the weaving and winding process. While the first support roller of the second group is preparing to continue the winding work, the material roller on the first support roller of the first group can be disassembled and replaced at the same time, which shortens the equipment downtime caused by the replacement of material roller, significantly increases the amount of weaving and winding per unit time, and improves the overall production efficiency.

[0015] 2. During winding, the first spring provides a pushing force to the first fixed block, pushing the connecting rod and tensioning roller to tighten the fabric. This ensures that the fabric maintains a suitable tension throughout the winding process, effectively reducing wrinkles and looseness after winding. It also ensures the flatness and tightness of the fabric on the roller after winding. Furthermore, the buffering effect of the first spring reduces the impact on the fabric caused by sudden tension fluctuations during winding, protecting the structural integrity of the fabric and improving the quality of the wound product.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 - Figure 6 This utility model provides an embodiment of a fabric tensioning and winding device, comprising a device body 1, a tensioning component disposed on the device body 1, a first motor 21 fixedly connected to the device body 1, a first gear 22 fixedly connected to the output end of the first motor 21, a second gear 23 meshing with the first gear 22, a rotating bracket 24 rotatably connected to the device body 1, a first support roller 210 rotatably connected to the rotating bracket 24, a limiting component disposed on the device body 1, a driving component disposed on the device body 1, and an adjusting component disposed on the driving component. The rotating bracket 24 is rotatably connected to the device body 1. When the first motor 21 is working, it drives the first gear 22 to rotate. When the first gear 22 rotates, it adjusts the rotating bracket 24 to flip by cooperating with the second gear 23. When the fabric tensioning and winding device is working, the first motor 21 is driven by the driving component to rotate the first gear 22. The support roller 210 and the connected take-up roller rotate to perform the take-up operation. During the take-up operation, the fabric is tightened by the tensioning component to prevent it from becoming too loose. After the first set of first support rollers 210 completes the take-up operation, the drive component is restricted by the adjustment limit component, and the drive component is disengaged from the first support roller 210. At this time, the first motor 21 drives the first gear 22 to rotate. By cooperating with the second gear 23, the rotating bracket 24 is adjusted to rotate on the rotating groove of the device body 1, which drives the two sets of first support rollers 210 to rotate. When the rotating bracket 24 rotates, the rotation of the rotating bracket 24 is restricted by the limit component. After the rotation, the other set of first support rollers 210 replaces the first support roller 210 that has completed the take-up operation. At this time, the second set of first support rollers 210 can be opened simultaneously to prepare for the continued take-up operation and to disassemble and replace the material rollers on the first set of first support rollers 210.

[0025] Please see Figure 1 - Figure 5In this embodiment, the main body 1 of the device has a limiting groove at the relative position of the rotating bracket 24. The rotating bracket 24 is rotatably connected to the groove, and the groove plays a precise limiting role in the rotation trajectory of the rotating bracket 24, which can effectively prevent the rotating bracket 24 from shifting laterally or shaking during the flipping process, so that the rotating bracket 24 always rotates smoothly along the preset trajectory. The driving component includes a first connecting seat 26 fixedly connected to the main body 1 of the device, a first electric push rod 27 fixedly connected to the first connecting seat 26, and a sliding rod 27 slidably connected to the first connecting seat 26. The sliding seat 28, the second motor 29 fixedly connected to the sliding seat 28, the rotating shaft 212 fixedly connected to the output end of the second motor 29, the first support roller 210 rotatably connected to the rotating bracket 24, and the connecting bushing 211 fixedly connected to the first support roller 210, the rotating shaft 212 being movably connected to the connecting bushing 211, the sliding seat 28 being fixedly connected to one end of the first electric push rod 27, the first electric push rod 27 working to push the sliding seat 28 and the second motor 29 to move, the rotating shaft 212 being in contact with the connecting bushing 211, the second electric push rod 27 working to push the sliding seat 28 and the second motor 29 to move, the second electric push rod 27 working to push the sliding seat 28 and the second motor 29 to move, the rotating shaft 212 being in contact with the connecting bushing 211, the second electric push rod 212 being in contact with the second motor 29 to move the sliding seat 28 and ... The working mechanism 29 drives the first support roller 210 to rotate. The first electric push rod 27 controls the movement distance of the sliding seat 28 and the second motor 29, realizing the engagement or disengagement of the rotating shaft 212 and the connecting sleeve 211, and controlling the start and stop of the first support roller 210. The guiding and limiting effect of the sliding seat 28 on the first connecting seat 26 ensures the smoothness of the movement of the second motor 29, avoiding poor docking between the rotating shaft 212 and the connecting sleeve 211 due to movement deviation. The connecting sleeve 211 has a groove, and the rotating shaft 212 is movably connected to the groove. The groove design ensures that when the connecting sleeve 211 is connected to the rotating shaft 212, the power of the second motor 29 can be transmitted to the first support roller 210, ensuring that the first support roller 210 winds up the fabric. The limiting component includes a fixing ring 214 fixedly connected to the rotating bracket 24, and a limiting block 213 fixedly connected to the main body 1 of the device. The limiting block 213 surrounds both sides of the fixing ring 214. By limiting both sides of the fixing ring 214, the limiting block 213 can precisely control the maximum rotation angle of the rotating bracket 24, effectively preventing the rotating bracket 24 from over-rotating.The adjustment assembly includes a first fixed bracket 215 fixedly connected to the first connecting seat 26, a first threaded rod 216 threadedly connected to the first fixed bracket 215, a first knob 217 fixedly connected to the first threaded rod 216, a first sliding rod 218 slidably connected to the first fixed bracket 215, a first limiting block 219 fixedly connected to one end of the first sliding rod 218, a second fixed bracket 220 fixedly connected to the rotating bracket 24, a second threaded rod 221 threadedly connected to the second fixed bracket 220, a second knob 222 fixedly connected to one end of the second threaded rod 221, a second sliding rod 223 slidably connected to the second fixed bracket 220, a second limiting block 224 fixedly connected to one end of the second sliding rod 223, and the end of the first threaded rod 216 away from the first knob 217 rotatably connected to the first limiting block 219. The end furthest from the second knob 222 is rotatably connected to the second limiting block 224. Rotating the first knob 217 adjusts the rotation of the first threaded rod 216, which in turn moves the first limiting block 219 and the first sliding rod 218. Rotating the second knob 222 adjusts the rotation of the second threaded rod 221, which in turn moves the second limiting block 224 and the second sliding rod 223. Rotating the knobs to rotate the threaded rods allows for adjustment of the limiting block position. The first sliding rod 218 and the second sliding rod 223 guide the movement of the first limiting block 219 and the second limiting block 224, respectively, preventing rotation or displacement of the limiting blocks during movement. The self-locking characteristic of the threaded connection ensures that the limiting blocks remain stably in the preset position after adjustment, preventing displacement due to device vibration and improving the reliability of the adjustment assembly.

[0026] Preferably, both the first limiting block 219 and the second limiting block 224 are provided with connecting slots. The first threaded rod 216 is rotatably connected to the slot of the first limiting block 219, and the second threaded rod 221 is rotatably connected to the second limiting block 224. The slots prevent the two threaded rods from driving the connected limiting blocks to rotate synchronously when they rotate, and can only push the connected limiting blocks to move linearly, thus avoiding the limiting failure caused by the rotation of the two limiting blocks.

[0027] Please see Figure 1 , Figure 6In this embodiment, the tensioning assembly includes a third threaded rod 31 rotatably connected to the device body 1, a third knob 32 fixedly connected to one end of the third threaded rod 31, a sliding block 33 threadedly connected to the third threaded rod 31, a third sliding rod 34 slidably connected to the sliding block 33, a first fixing block 35 fixedly connected to one end of the third sliding rod 34, a first spring 36 fixedly connected between the sliding block 33 and the first fixing block 35, a connecting rod 37 fixedly connected to the first fixing block 35, and a tensioning roller 38 rotatably connected to the connecting rod 37. The sliding block 33 is slidably connected to the device body 1. The rotation of the third knob 32 drives the third threaded rod 31 to rotate, and the third threaded rod 34... 1. Rotating the adjusting sliding block 33 moves the fabric. The cooperation between the third knob 32 and the third threaded rod 31 can precisely adjust the position of the sliding block 33, thereby changing the contact position between the tensioning roller 38 and the fabric, adapting to the tensioning requirements of fabrics of different widths. The elasticity of the first spring 36 enables the tensioning roller 38 to automatically adjust the pressure according to the tension changes of the fabric, avoiding breakage or loosening caused by sudden changes in fabric tension, and ensuring that the tension of the fabric is always uniform during the winding process. The third sliding rod 34 guides the movement of the first fixed block 35, ensuring that the tensioning roller 38 remains horizontal during the pressure adjustment process, avoiding uneven force on the fabric due to tilting, and further improving the flatness of the fabric winding.

[0028] When the fabric tensioning and winding device is in operation, before winding, the third threaded rod 31 is rotated by the third knob 32, which drives the sliding block 33 to move on the main body 1 of the device. Then, the tensioning roller 38 is adjusted in position by the third sliding rod 34, the first fixed block 35, and the connecting rod 37. After the fabric is passed between multiple sets of tensioning rollers 38 and fixed to the winding roller on the first support roller 210, the sliding seat 28 is pushed to slide on the first connecting seat 26 by the first electric push rod 27, which drives the second motor 29 to move, so that the rotating shaft 212 is in contact with the groove on the connecting sleeve 211 of the first support roller 210 to start the winding work. During winding, the rotating shaft 212 is driven to rotate by the second motor 29, and the first support roller 210 and the connected winding roller are driven to rotate by the connecting sleeve 211 to perform the winding work. During the winding process, the first spring 36 pushes the first fixed block 35 to push the connecting rod 37 and the tensioning roller 38.

[0029] After the first set of first support rollers 210 completes the winding operation, the first knob 217 rotates, causing the first threaded rod 216 to rotate. The rotation of the first threaded rod 216 causes the first sliding rod 218 and the first limiting block 219 to move. After the first limiting block 219 engages with the rotating shaft 212, it restricts the rotation of the rotating shaft 212. Then, the second knob 222 rotates, causing the second threaded rod 221 to rotate. The rotation of the second threaded rod 221 causes the second sliding rod 223 and the second limiting block 224 to move. The second limiting block 224 engages with the connecting bushing 211, thus restricting the rotation of the connecting bushing 211. The rotation is restricted, and then the first electric push rod 27 pulls the sliding seat 28 and the second motor 29 to move, so that the rotating shaft 212 is separated from the connecting sleeve 211 of the first support roller 210. At this time, the first motor 21 works to drive the first gear 22 to rotate. The first gear 22 meshes with the second gear 23, which drives the rotating bracket 24 to flip on the rotating groove of the main body 1 of the device, thereby driving the two sets of first support rollers 210 to flip. During the flipping process of the rotating bracket 24, the fixing ring 214 of the limiting component moves with the rotating bracket 24. The limiting block 213 controls the flipping range of the rotating bracket 24 by limiting the fixing ring 214.

[0030] After the rotating bracket 24 is rotated into position, another set of first support rollers 210 replaces the first support rollers 210 that have completed winding. At this time, the first electric push rod 27 pushes the sliding seat 28 and the second motor 29 to move again, so that the rotating shaft 212 fits into the groove on the connecting sleeve 211 of the first support roller 210, ready to continue the winding work. At the same time, the material rollers on the first set of first support rollers 210 can be disassembled and replaced simultaneously.

[0031] Through the above steps, this alternating operation mode can ensure the continuity of the weaving and winding process. While the second set of first support rollers 210 is preparing to continue winding, the material rollers on the first set of first support rollers 210 can be disassembled and replaced simultaneously to solve the problem that the replacement process of a single support roller design is cumbersome, time-consuming and labor-intensive in actual use, which seriously affects the entire production process.
