Description

Technical Field

[0001] This utility model relates to the technical field of fabric roll storage devices, specifically to a fabric roll storage device for a double-sided circular knitting machine. Background Technology

[0002] Fabric roll storage devices for double-sided circular knitting machines are typically used to efficiently collect and organize the fabric generated during the production process. During knitting, fabric is continuously output from the circular knitting machine. The fabric roll storage device ensures that the fabric is neatly rolled up, preventing it from becoming scattered or knotted. By winding the fabric into a compact roll, it saves storage space and facilitates subsequent storage and transportation. The fabric roll storage device ensures that the fabric is neatly wound, avoids waste, improves production efficiency, and prepares the fabric for subsequent processing. Chinese Patent Publication No. CN220812841U discloses a fabric winding and storage device for a double-sided circular knitting machine, including two symmetrically arranged support frames. The inner side of each support frame has a guide groove, and a winding roller is centrally located on the opposite side of the two support frames. A drive motor is fixedly connected to the outer side of one of the support frames, and a threaded cylinder is fixedly connected to the outer side of the other support frame. A handwheel is located on the outer side of the threaded cylinder. A pair of adjusting blocks are located on the opposite side of the drive motor and the threaded cylinder. This fabric winding and storage device for a double-sided circular knitting machine enables quick installation and removal of the winding roller, solving the problems of inconvenient repositioning and use of the winding roller structure, improving the fabric winding efficiency, and achieving rapid fabric fixation. This solves the problem of loosening and falling off due to unstable fabric connections, and improves the stability of the fabric winding and storage device. The aforementioned patent mentions that one end of the fabric is placed inside the inner groove, and then the sliding bar is moved to reset, so that the sealing cover engages with the winding roller, fixing the position of one end of the fabric. However, due to the flexibility of the fabric, when the sliding bar is driven to reset, one side of the fabric end will be squeezed and pulled against one end of the sliding bar first. At this time, the fabric end is subjected to uneven force, making the fabric prone to deformation and wrinkles. This makes it easy to generate uneven pressure when the fabric is wound up, resulting in indentations in local areas and uneven stacking during winding. Therefore, we propose a fabric winding and storage device for a double-sided circular knitting machine. Utility Model Content

[0003] To address the aforementioned issues, a fabric roll-up storage device for a double-sided circular knitting machine is provided. This device applies uniform pressure to one side of the fabric via a fabric roll-up positioning mechanism. This uniform pressure effectively prevents uneven pulling or compression of the fabric ends, reducing fabric deformation and wrinkles. It solves the technical problem that when the fabric roll-up storage device limits one side of the fabric, wrinkles easily occur, leading to uneven pressure during roll-up, resulting in indentations in localized areas and uneven roll-up accumulation.

[0004] To address the existing technical problems, this utility model provides a fabric winding and storage device for a double-sided circular knitting machine, including a support frame, a motor mounted on one side of the support frame, a winding rod mounted on the support frame, placement grooves on both sides of the support frame near the winding rod, and ball bearings movably embedded on the side of the winding rod near the placement groove; a fabric winding positioning mechanism is provided on the winding rod to restrict one side of the fabric to the winding rod during the fabric winding process; and a transmission mechanism is provided on one end of the motor and the winding rod to transmit the motor power to the winding rod.

[0005] Preferably, the fabric roll positioning mechanism includes a first extrusion rod, a second extrusion rod, a first gear, and a second gear; the first extrusion rod is movably mounted on the take-up rod; the second extrusion rod is also movably mounted on the take-up rod; the first gear is movably mounted on the take-up rod and is connected to both ends of the first extrusion rod; the second gear is movably mounted on the take-up rod and is connected to both ends of the second extrusion rod.

[0006] Preferably, the fabric positioning mechanism further includes a transmission component, a handwheel, and a displacement mechanism; the transmission component is disposed at one end of the take-up rod, and is used to drive the first extrusion rod and the second extrusion rod to rotate in opposite directions; the handwheel is movably disposed on the take-up rod, and the handwheel is connected to the working end of one side of the transmission component; the displacement mechanism is disposed on the take-up rod and the handwheel, and is used to push the first toothed plate to engage with the second toothed plate, preventing the handwheel from rotating arbitrarily under the action of external force.

[0007] Preferably, the transmission assembly includes a first synchronous pulley and a second synchronous pulley; the first synchronous pulley is movably mounted on the winding rod and is connected to a first gear; the second synchronous pulley is also movably mounted on the winding rod and is connected to a second gear, which is connected to a handwheel.

[0008] Preferably, the displacement mechanism includes a threaded groove, a sleeve, a first toothed plate, and a second toothed plate; the threaded groove is opened on the outside of the handwheel; the sleeve is sleeved on the handwheel and threadedly connected to the threaded groove; the first toothed plate is rotatably mounted on the sleeve; the second toothed plate is mated with the first toothed plate and connected to the winding rod.

[0009] Preferably, the displacement mechanism further includes a guide mechanism, which assists the first toothed plate in linear movement. The guide mechanism includes a slider and a groove. The slider is connected to the first toothed plate. The groove is located on the side of the handwheel near the slider and is used to cooperate with the slider in linear movement.

[0010] Preferably, the transmission mechanism includes a receiving slot, a connecting pipe, and a docking block; the receiving slot is located at the end of the winding rod away from the transmission component; the connecting pipe is slidably connected to the receiving slot; the docking block is connected to the connecting pipe and is connected to the output end of the motor.

[0011] Preferably, the transmission mechanism further includes a limiting mechanism for confining the connecting tube and the mating block together. The limiting mechanism includes a threaded tube and a bolt; the threaded tube is connected to the inside of the connecting tube. The bolt is threadedly connected to the threaded tube through a sliding receiving groove.

[0012] The advantages of this utility model compared to the prior art are: 1. By applying uniform pressure to one side of the fabric through the fabric positioning mechanism, the uniform pressure can effectively avoid uneven pulling or compression of the fabric end, making it easier for the fabric to adhere evenly to the take-up bar. Local indentations are less likely to occur, reducing fabric deformation and wrinkles. This solves the technical problem that wrinkles are easily caused when the fabric is limited on one side by the fabric take-up device, which leads to uneven pressure during fabric take-up, resulting in indentations in local areas and uneven stacking during take-up.

[0013] 2. The displacement mechanism can stably restrain the fabric and the winding rod together, preventing the fabric from being irregularly packed due to loosening or displacement during the winding process. This improves the stability and accuracy of the fabric winding process and solves the technical problems caused by the fabric being loose or displaced during winding, resulting in irregular fabric packing, low winding accuracy, inconsistent fabric shape after winding, and affecting subsequent use.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1-2 As shown, a fabric winding and storage device for a double-sided circular knitting machine includes a support 1, a motor 11 on one side of the support 1, a winding rod 12 on the support 1, and placement grooves 2 on both sides of the support 1 near the winding rod 12. A ball bearing 21 is movably embedded on the side of the winding rod 12 near the placement groove 2. A fabric winding positioning mechanism is provided on the winding rod 12 to restrict one side of the fabric to the winding rod 12 during the fabric winding process. A transmission mechanism is provided on one end of the motor 11 and the winding rod 12 to transmit power from the motor 11 to the winding rod 12.

[0025] Specifically, during the operation of the fabric winding and storage device, both ends of the winding rod 12 are placed inside the mounting groove 2. The ball bearings 21 embedded in the mounting groove 2 reduce the coefficient of friction between the winding rod 12 and the mounting groove 2. Subsequently, the output end of the motor 11 is connected to one end of the winding rod 12 through a transmission mechanism. If the motor 11 is started, the power of the motor 11 can be transmitted through the transmission mechanism to drive the winding rod 12 to rotate.

[0026] After the motor 11 is connected to the take-up bar 12, place one end of the fabric in the upper through groove of the take-up bar 12. Use the fabric positioning mechanism to limit and fix that end of the fabric, so that the fabric and the take-up bar 12 are constrained. At this time, start the motor 11 again, and the take-up bar 12 will rotate to neatly collect the fabric on its outer surface.

[0027] See Figures 1-3 , Figure 6 and Figure 8 As shown, the fabric winding positioning mechanism includes a first pressing rod 22, a second pressing rod 221, a first gear 23, and a second gear 24. The first pressing rod 22 is movably mounted on the take-up rod 12. The second pressing rod 221 is also movably mounted on the take-up rod 12. The first gear 23 is movably mounted on the take-up rod 12 and is connected to both ends of the first pressing rod 22. The second gear 24 is movably mounted on the take-up rod 12 and is connected to both ends of the second pressing rod 221. The fabric winding positioning mechanism also includes a transmission assembly, a handwheel 25, and a displacement mechanism. The transmission assembly is located at one end of the take-up rod 12 and is used to drive the first pressing rod 22 and the second pressing rod 221. The extrusion rod 221 rotates in the opposite direction; the handwheel 25 is movably mounted on the take-up rod 12 and is connected to the working end of the transmission assembly; a displacement mechanism is mounted on the take-up rod 12 and the handwheel 25, and the displacement mechanism is used to push the first toothed plate 210 to engage with the second toothed plate 211 to prevent the handwheel 25 from rotating arbitrarily under the action of external force; the transmission assembly includes a first synchronous wheel 26 and a second synchronous wheel 27; the first synchronous wheel 26 is movably mounted on the take-up rod 12 and is connected to the first gear 23; the second synchronous wheel 27 is also movably mounted on the take-up rod 12 and is connected to the second gear 24, which is connected to the handwheel 25.

[0028] Specifically, deformable rubber pads are connected to the outer sides of the first extrusion rod 22 and the second extrusion rod 221, and the two rubber pads are in a state of mutual compression. The first gear 23 and the second gear 24 form a meshing transmission, and the first synchronous pulley 26 and the second synchronous pulley 27 also form a meshing transmission relationship.

[0029] When one end of the fabric is placed in the upper slot of the take-up bar 12, the fabric is simultaneously positioned between the first extrusion bar 22 and the second extrusion bar 221. Rotating the handwheel 25 causes the second synchronous wheel 27 to rotate. Based on the meshing transmission characteristics of the first synchronous wheel 26 and the second synchronous wheel 27, the first synchronous wheel 26 rotates accordingly. The rotation of the first synchronous wheel 26 further drives the first gear 23 to rotate. Through the meshing transmission between the first gear 23 and the second gear 24, the second gear 24 is driven to rotate, thereby driving the first extrusion bar 22 and the second extrusion bar 221 to rotate in opposite directions.

[0030] Because the deformable rubber pads connected to the outer sides of the first extrusion rod 22 and the second extrusion rod 221 press against each other, during the counter-rotation of the first extrusion rod 22 and the second extrusion rod 221, extrusion pressure can be applied to the fabric between them, achieving synchronous pulling of the fabric and firmly clamping one end of the fabric between the first extrusion rod 22 and the second extrusion rod 221. This ensures that the first extrusion rod 22 and the second extrusion rod 221 can apply uniform pressure to the fabric, effectively avoiding local damage or wrinkles to the fabric caused by uneven pressure distribution, and making it easier for the fabric to adhere evenly to the winding rod 12 when the fabric winding and storage device is in operation. After the fabric is clamped, the displacement mechanism is used to limit the handwheel 25 to prevent the first extrusion rod 22 and the second extrusion rod 221 from loosening or shifting.

[0031] See Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the displacement mechanism includes a threaded groove 28, a sleeve 29, a first toothed plate 210, and a second toothed plate 211. The threaded groove 28 is located on the outside of the handwheel 25. The sleeve 29 is fitted onto the handwheel 25 and is threadedly connected to the threaded groove 28. The first toothed plate 210 is rotatably mounted on the sleeve 29. The second toothed plate 211 is mated with the first toothed plate 210 and is connected to the winding rod 12. The displacement mechanism also includes a guide mechanism, which assists the first toothed plate in linear movement. The guide mechanism includes a slider 212 and a groove 213. The slider 212 is connected to the first toothed plate 210. The groove 213 is located on the side of the handwheel 25 near the slider 212 and is used to cooperate with the slider 212 in linear movement.

[0032] Specifically, the slider 212 and the groove 213 are designed to be compatible.

[0033] After the first extrusion rod 22 and the second extrusion rod 221 complete the limiting operation on the fabric, the rotating sleeve 29, due to the threaded connection between the sleeve 29 and the threaded groove 28, allows the sleeve 29 to undergo linear displacement along the slide groove 213. During this displacement, the sleeve 29 drives the first toothed plate 210 to move closer to the second toothed plate 211. Simultaneously, as the first toothed plate 210 moves, the slider 212 connected to the first toothed plate 210 slides along the slide groove 213. Based on the matching relationship between the slider 212 and the slide groove 213, the rotation of the first toothed plate 210 is effectively restricted, providing guiding assistance for the linear movement of the first toothed plate 210. Finally, the first toothed plate 210 and the second toothed plate 211 are docked and form a constraint, thereby restricting the rotation of the handwheel 25. This ensures that the first extrusion rod 22 and the second extrusion rod 221 maintain a stable limiting state on the fabric, keeping the fabric stably bound to the winding rod 12, thus making it easy for the fabric winding and storage device to stably store the fabric.

[0034] See Figures 1-3 , Figure 5 and Figure 7 As shown, the transmission mechanism includes a receiving groove 214, a connecting pipe 215, and a docking block 216. The receiving groove 214 is located at the end of the winding rod 12 away from the transmission assembly. The connecting pipe 215 is slidably connected to the receiving groove 214. The docking block 216 is connected to the connecting pipe 215 and is connected to the output end of the motor 11. The transmission mechanism also includes a limiting mechanism for restricting the connecting pipe 215 and the docking block 216 together. The limiting mechanism includes a threaded tube 217 and a bolt 218. The threaded tube 217 is connected to the inner side of the connecting pipe 215. The bolt 218 is threadedly connected to the threaded tube 217 and can slide through the receiving groove 214.

[0035] Specifically, the inner side of the storage slot 214 and the outer side of the connecting pipe 215 are fitted together, and the cross-section of the storage slot 214 is rectangular. The inner side of the connecting pipe 215 and the outer side of the connecting block 216 are also fitted together, and the cross-section of the connecting block 216 is also rectangular.

[0036] After the take-up rod 12 is constrained with the fabric, the connecting pipe 215 is pulled to slide along the inner side of the storage groove 214. Based on the fit between the inner side of the storage groove 214 and the outer side of the connecting pipe 215, and the rectangular cross-sectional characteristics of the storage groove 214, the connecting pipe 215 has good stability during movement, effectively suppressing shaking, thereby ensuring that it can accurately and stably connect with the docking block 216. After the connecting pipe 215 and the docking block 216 are connected, a bolt 218 and a threaded tube 217 are used for threaded connection. The threaded engagement of the two achieves a tight constraint, making the connecting pipe 215 firmly fixed to the outer side of the docking block 216.

[0037] At this time, motor 11 is started, and the output of motor 11 drives the docking block 216 to rotate. Due to the fit between the inner side of the docking tube 215 and the outer side of the docking block 216, and the rectangular cross-section design of the docking block 216, the docking block 216 can effectively transmit the rotational motion to the docking tube 215. Then, the docking tube 215 drives the take-up rod 12 to rotate through the storage groove 214. During this process, the ball bearing 21 plays a drag-reducing role, reducing the frictional resistance between the take-up rod 12 and the bracket 1, ensuring that the take-up rod 12 completes the fabric take-up operation smoothly and efficiently.

[0038] Working Principle: During the operation of the fabric winding and storage device, the winding rod 12 is first placed in the placement slot 2, and then the fabric is placed between the first extrusion rod 22 and the second extrusion rod 221. By rotating the handwheel 25, the first extrusion rod 22 and the second extrusion rod 221 are driven to perform extrusion and limiting operations on the fabric. After the fabric is limited, the sleeve is rotated to make the first toothed plate 210 and the second toothed plate 211 align, preventing relative loosening between the first extrusion rod 22 and the second extrusion rod 221, and ensuring a stable constraint relationship between the fabric and the winding rod 12. Then, the connecting pipe 215 is pulled to align with the connecting block 216, and the connecting pipe 215 is fixed to the outside of the connecting block 216 by the threaded connection of the bolt 218 and the threaded connection of the screw tube 217. After starting the motor 11, the power of the motor 11 is transmitted through the connecting block 216 and the connecting pipe 215, stably driving the winding rod 12 to rotate, realizing the stable winding operation of the fabric by the fabric winding and storage device.

[0039] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
