[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] Example 1, as Figures 1 to 5 As shown, the present invention provides a fabric winding device, including a frame 1, an mounting plate 2 fixedly mounted on the frame 1, a lifting assembly below the mounting plate 2, and a lifting plate 3 above the mounting plate 2. The driving end of the lifting assembly passes through the mounting plate 2 and is connected to the lifting plate 3, and is used to drive the lifting plate 3 to move up and down.

[0032] The upper surface of the lifting plate 3 is equipped with a first ball screw slide 4 and a second ball screw slide 5 on the left and right sides respectively. The left spline shaft 7 is rotatably connected above the first ball screw slide 4 through the left support bearing seat 6. The right spline shaft 8 is rotatably connected above the second ball screw slide 5 through the right support bearing seat 19. The right end of the left spline shaft 7 and the left end of the right spline shaft 8 are respectively connected to the two ends of the central shaft 9 through couplings. The left spline shaft 7, the right spline shaft 8 and the central shaft 9 are coaxially arranged. The driven gear 10 is installed in the middle of the central shaft 9. The upper surface of the lifting plate 3 is fixedly installed with a rotary motor 11. The drive end of the rotary motor 11 is equipped with a drive gear 12. The driven gear 10 and the drive gear 12 are connected by a synchronous belt drive.

[0033] A left pulley mounting bracket 14 is slidably connected above the first ball screw slide table 4 via a first screw slider 13. A left rotating shaft 15 is installed in the left pulley mounting bracket 14, and the right end of the left rotating shaft 15 extends out of the left pulley mounting bracket 14. The left rotating shaft 15 and the left spline shaft 7 are connected by a first synchronous belt pulley assembly. A right pulley mounting bracket 17 is slidably connected above the second ball screw slide table 5 via a second screw slider 16. A right rotating shaft 18 is installed in the right pulley mounting bracket 17, and the left end of the right rotating shaft 18 extends out of the right pulley mounting bracket 17 and corresponds to the right end of the left rotating shaft 15. The right rotating shaft 18 and the right spline shaft 8 are connected by a second synchronous belt pulley assembly.

[0034] A worktable 20 is installed above the frame 1. The worktable 20 is located above the left spline shaft 7 and the right spline shaft 8, and below the left rotating shaft 15 and the right rotating shaft 18. A storage box 21 is provided above the worktable 20.

[0035] Working principle:

[0036] Before winding, each roll is placed in the storage box 21, and the fabric to be wound is laid on the corresponding position above the workbench 20. According to the width of the fabric, the first ball screw slide 4 and the second ball screw slide 5 are controlled to drive the left pulley mounting frame 14 and the right pulley mounting frame 17 to move respectively. This allows the distance between the left pulley mounting frame 14 and the right pulley mounting frame 17 to be adjusted, thereby adjusting the relative distance between the left end of the right rotating shaft 18 and the right end of the left rotating shaft 15, so as to adapt to the winding of products of different specifications.

[0037] During winding, a contouring tool head matching the reel is first installed on the right end of the left rotating shaft 15 and the left end of the right rotating shaft 18. Then, a reel is taken out from the storage box 21 and the two ends of the reel are aligned with the right end of the left rotating shaft 15 and the left end of the right rotating shaft 18, respectively. Then, the first ball screw slide 4 and the second ball screw slide 5 are controlled to drive the left pulley mounting frame 14 and the right pulley mounting frame 17 to move, so that the reel can be clamped and fixed by the contouring tool head on the right end of the left rotating shaft 15 and the contouring tool head on the left end of the right rotating shaft 18. The drive end of the control motor 11 drives the driven gear 10 to rotate at a certain angle, thereby driving the drive gear 12 and the central shaft 9 to rotate synchronously through the transmission action of the synchronous belt. Since the two ends of the central shaft 9 are coaxially connected to the left spline shaft 7 and the right spline shaft 8 through couplings, the left spline shaft 7 and the right spline shaft 8 can be driven to rotate synchronously. Since the left spline shaft 7 is connected to the left rotating shaft 15 through the first synchronous belt pulley assembly, and the right spline shaft 8 is connected to the right rotating shaft 18 through the second synchronous belt pulley assembly, the left rotating shaft 15 and the right rotating shaft 18 can be driven to rotate synchronously. In turn, the reel between the left rotating shaft 15 and the right rotating shaft 18 can be driven to rotate at a certain angle, so that the adhesive strip on the surface of the reel faces directly downward. At this point, the anti-adhesive layer on the surface of the adhesive strip can be manually peeled off, and then the lifting assembly can be controlled to move the entire lifting plate 3 downward, thereby moving the left rotating shaft 15, the right rotating shaft 18, and the middle winding shaft downward. This allows the adhesive strip on the surface of the winding shaft to adhere to the fabric product on the surface of the workbench, thus effectively ensuring that the fabric product can be flatly adhered to the surface of the winding shaft when the winding begins.

[0038] Next, the lifting assembly is controlled to move the entire lifting plate 3 upward to a suitable position. Then, the adhesion between the product and the roll can be manually tightened to further ensure the flatness and stability of the adhesion between the product end and the roll. Then, the rotating motor 11 is controlled to operate, thereby driving the central shaft 9 to rotate through the transmission connection between the driven gear 10 and the driving gear 12. This, in turn, drives the left splined shaft 7 and the right splined shaft 8 at both ends of the central shaft 9 to rotate synchronously. Through the transmission connection of the first and second synchronous pulley assemblies, the left rotating shaft 15 and the right rotating shaft 18 can be driven to rotate synchronously, thereby driving the roll between the left and right rotating shafts to rotate, thus achieving automatic product winding.

[0039] After winding is completed, the first ball screw slide 4 and the second ball screw slide 5 can be controlled to drive the left pulley mounting bracket 14 and the right pulley mounting bracket 17 to their initial positions respectively, so that the roll can be separated from the left rotating shaft 15 and the right rotating shaft 18. Then the wound product can be taken out from the frame 1.

[0040] In Embodiment 2, as a further preferred embodiment of Embodiment 1, the lifting assembly includes a mounting frame 22, a lifting frame 23, and a lifting screw motor 24. The mounting frame 22 is fixedly mounted on the lower surface of the mounting plate 2. The lifting screw motor 24 is mounted below the mounting frame 22. The drive end of the lifting screw motor 24 is connected to the lower end of the lifting ball screw 25 via a coupling. The lifting ball screw 25 is rotatably connected to the mounting frame 22 via a bearing. The lifting frame 23 is fixedly mounted on the lower surface of the lifting plate 3. A through hole is provided on the surface of the mounting plate 2. The lifting frame 23 passes through the through hole and moves up and down along the through hole. A screw nut 39 is embedded in the lower surface of the lifting frame 23. The upper end of the lifting ball screw 25 passes through the screw nut 39 and is threadedly connected to the screw nut 39.

[0041] Therefore, when it is necessary to control the lifting assembly to drive the entire lifting plate 3 to move up and down, the lifting screw motor 24 can be controlled to operate, thereby driving the lifting ball screw 25 to rotate through the drive end of the lifting screw motor 24. Since the screw nut 39 and the lifting ball screw 25 are connected by threads, the screw nut 39 can be driven to move up and down along the axial direction of the lifting ball screw 25, thereby driving the lifting frame 23 to move up and down along the through hole, and then driving the entire lifting plate 3 to move up and down.

[0042] In addition, in this embodiment, a sensor bracket can be installed on the upper surface of the mounting plate 2, and proximity switches can be installed at corresponding positions above and below the sensor bracket. A sensing plate can be installed on the side of the lifting plate 3 so that the sensing plate corresponds to the sensing end of the proximity switch. Thus, the proximity switch can be connected to the controller, and the lifting screw motor 24 can be controlled by the controller to control the range of vertical movement of the lifting plate 3.

[0043] In Example 3, as a further preferred embodiment of Example 2, multiple guide posts 37 are vertically fixedly installed on the lower surface of the lifting frame 23, and multiple guide sleeves 38 are fixedly embedded in the surface of the mounting plate 2. Each guide post 37 corresponds to a guide sleeve 38, and each guide post 37 passes through and is movably connected to its corresponding guide sleeve 38. By setting multiple guide posts 37 and allowing each guide post 37 to move up and down within the guide sleeve 38, when controlling the entire lifting plate 3 to move up and down, the lifting plate 3 can be guided and controlled through each guide post 37. This effectively avoids the problem of offset when the lifting plate 3 moves up and down, thereby ensuring the accuracy and stability of the entire device.

[0044] Example 4, as a further preferred embodiment of Example 1, the first ball screw slide 4 includes a first ball screw 41, a first screw motor 42, and two parallel first slide rails 43. The two ends of the first ball screw 41 are rotatably connected to the lower end of the left support bearing seat 6 through bearings. One end of the first ball screw 41 passes through the left support bearing seat 6 and is connected to the drive end of the first screw motor 42 through a coupling. The two ends of the lower surface of the first screw slider 13 are slidably connected to the first slide rails 43. The middle of the lower surface of the first screw slider 13 is threadedly connected to the first ball screw 41 through a screw nut.

[0045] The second ball screw slide 5 includes a second ball screw 51, a second screw motor 52, and two parallel second slide rails 53. The two ends of the second ball screw 51 are rotatably connected to the lower end of the right support bearing seat 19 through bearings. One end of the second ball screw 51 passes through the right support bearing seat 19 and is connected to the drive end of the second screw motor 52 through a coupling. The two ends of the lower surface of the second screw slider 16 are slidably connected to the second slide rails 53. The middle of the lower surface of the second screw slider 16 is threadedly connected to the second ball screw 51 through a screw nut.

[0046] When it is necessary to control the left pulley mounting bracket 14 to move in the left and right directions, the first lead screw motor 42 can be operated to drive the first ball screw 41 to rotate. This allows the lead screw nut in the middle of the lower surface of the first lead screw slider 13 to connect with the first ball screw 41 via a threaded connection, thereby moving the first lead screw slider 13 along the axial direction of the first ball screw 41, and subsequently moving the left pulley mounting bracket 14 in the left and right directions. When it is necessary to control the right pulley mounting bracket 17 to move in the left and right directions, the second lead screw motor 52 can be operated to drive the second ball screw 51 to rotate. This allows the lead screw nut in the middle of the lower surface of the second lead screw slider 16 to connect with the second ball screw 51 via a threaded connection, thereby moving the second lead screw slider 16 along the axial direction of the second ball screw 51, and subsequently moving the right pulley mounting bracket 17 in the left and right directions.

[0047] In Example 5, as a further preferred embodiment of Example 1, two central bearing seats 26 are fixedly installed on the upper surface of the lifting plate 3. The central shaft 9 is rotatably connected to the two central bearing seats 26 via bearings, and the driven gear 10 is located between the two central bearing seats 26. Through the joint support of the two central bearing seats 26, the stability of the central shaft 9 during rotation is effectively guaranteed.

[0048] In Embodiment Six, as a further preferred embodiment of Embodiment One, the first synchronous belt pulley assembly includes a first bushing 27 and a first driven tooth 28. The first bushing 27 is slidably but non-rotatably mounted on the outer surface of the left spline shaft 7. Specifically, in this embodiment, a strip groove can be provided axially on the surface of the left spline shaft 7, and a spline is provided on the inner wall of the first bushing 27. Thus, the sliding connection of the spline in the strip groove can achieve the slidable but non-rotatable assembly effect between the first bushing 27 and the left spline shaft 7. The left and right ends of the first bushing 27 are movably connected to the two side walls of the left pulley mounting bracket 14 through the bushing. A first driving tooth 29 is fixedly mounted on the outer surface of the first bushing 27, and the first driven tooth 28 is fixedly mounted on the outer surface of the left rotating shaft 15. The first driven tooth 28 and the first driving tooth 29 are connected by a first synchronous belt 30.

[0049] The second synchronous belt pulley assembly includes a second bushing 31 and a second driven tooth 32. The second bushing 31 is slidably but non-rotatably mounted on the outer surface of the right spline shaft 8. Specifically, in this embodiment, a strip groove can be provided axially on the surface of the right spline shaft 8, and a spline is provided on the inner wall of the second bushing 31. Thus, the sliding connection of the spline in the strip groove can achieve the slidable but non-rotatable assembly effect between the second bushing 31 and the right spline shaft 8. The left and right ends of the second bushing 31 are movably connected to the two side walls of the right pulley mounting bracket 17 through the bushing. A second driving tooth 33 is fixedly mounted on the outer surface of the second bushing 31, and the second driven tooth 32 is fixedly mounted on the outer surface of the right rotating shaft 18. The second driven tooth 32 and the second driving tooth 33 are connected by a second synchronous belt 34.

[0050] When the rotating motor 11 is operated to drive the left spline shaft 7 and the right spline shaft 8 to rotate synchronously via the central shaft 9, the left spline shaft 7 drives the first bushing 27 on its surface to rotate. Then, utilizing the transmission connection between the first driving tooth 29 and the first driven tooth 28 on the outer surface of the first bushing 27 through the first synchronous belt 30, the first driven tooth 28 rotates synchronously, thereby driving the left rotating shaft 15 to rotate synchronously. Similarly, the right spline shaft 8 drives the second bushing 31 on its surface to rotate. Utilizing the transmission connection between the second driving tooth 33 and the second driven tooth 32 on the outer surface of the second bushing 31 through the second synchronous belt 34, the second driven tooth 32 rotates synchronously, thereby driving the right rotating shaft 18 to rotate synchronously.

[0051] Furthermore, since the left and right ends of the first bushing 27 are movably connected to the side walls of the left pulley mounting bracket 14 via bushings, the position of the first bushing 27 within the left pulley mounting bracket 14 can be limited by the bushings, while also allowing the left spline shaft 7 to slide and rotate with the left pulley mounting bracket 14. Similarly, since the left and right ends of the second bushing 31 are movably connected to the side walls of the right pulley mounting bracket 17 via bushings, the position of the second bushing 31 within the right pulley mounting bracket 17 can be limited by the bushings, while also allowing the right spline shaft 8 to slide and rotate with the right pulley mounting bracket 17.

[0052] In Example 7, as a further preferred embodiment of Example 6, a first clamping wheel 35 is rotatably mounted within the left pulley mounting bracket 14 via a mounting shaft. The first clamping wheel 35 presses against the outer surface of the first synchronous belt 30. Similarly, a second clamping wheel 36 is rotatably mounted within the right pulley mounting bracket 17 via a mounting shaft. The second clamping wheel 36 presses against the outer surface of the second synchronous belt 34. The first clamping wheel 35 achieves a clamping effect on the first synchronous belt 30, ensuring stable tension. Likewise, the second clamping wheel 36 achieves a clamping effect on the second synchronous belt 34, ensuring stable tension.

[0053] Example 8, as a further preferred embodiment of Example 1, the storage frame 21 includes a square frame 211, which is fixedly installed on the frame 1. A V-shaped hopper 212 is installed in the middle of the square frame 211. A baffle 213 is installed on the upper surface of the workbench 20. A telescopic cylinder 214 is installed on the rear side of the upper surface of the workbench 20. The telescopic shaft of the telescopic cylinder 214 corresponds to the front and rear of the baffle 213. The discharge port of the V-shaped hopper 212 is located between the telescopic cylinder 214 and the baffle 213.

[0054] Therefore, during operation, multiple reels can be horizontally placed in the V-shaped hopper 212. The lowest reel can fall onto the worktable 20 through the opening at the bottom of the V-shaped hopper 212 and be blocked by the baffle 213. When a reel needs to be retrieved, the telescopic shaft of the telescopic cylinder 214 can be extended, pushing the reel at the bottom opening of the V-shaped hopper 212 past the baffle 213 for direct retrieval. Afterward, when the telescopic shaft of the telescopic cylinder 214 retracts, the lowest reel in the V-shaped hopper 212 will fall back onto the worktable 20 through the opening at the bottom of the V-shaped hopper 212 and be blocked by the baffle 213. This process is repeated to achieve rapid retrieval of the reels. In this embodiment, a door can be provided at the rear of the frame 1 for adding reels to the V-shaped hopper 212.

[0055] In Example 9, as a further preferred embodiment of Example 1, a rubber pad 201 is installed on the upper surface of the workbench 20. The rubber pad 201 corresponds vertically to the left rotating shaft 15 and the right rotating shaft 18. A hopper 203 is provided below the front side of the workbench 20. Thus, when the roll moves downwards under the action of the lifting assembly to adhere to the fabric, the rubber pad 201 effectively cushions the adhesion between the roll and the product. The hopper 203 can be used to store the fabric to be rolled up.

[0056] Example 10, a further preferred embodiment of Example 1, includes a limiting plate 202 installed on the left side of the upper surface of the workbench 20. The limiting plate 202 is positioned along the front-to-back direction of the workbench 20, and a locking pin is installed on its surface. Multiple locking holes are evenly distributed along the left-to-right direction on the upper surface of the workbench 20. The limiting plate 202 is connected and fixed by the locking pins engaging with the locking holes. The limiting plate 202 restricts the position of the fabric product on the workbench, ensuring rapid product positioning. Furthermore, for products of different specifications, the position of the limiting plate 202 along the left-to-right direction of the workbench 20 can be adjusted to accommodate the positioning requirements of different product specifications. Once the limiting plate 202 is adjusted to the appropriate position, the locking pins engaging with the locking holes lock and fix the limiting plate 202 in place.

[0057] In this invention, a controller can also be installed on the side of the frame 1, and the signal output terminal of the controller can be connected to the signal input terminals of the rotary motor 11, the lifting screw motor 24, the first screw motor 42, the second screw motor 52, and the telescopic cylinder 214, respectively. Thus, the control chip within the controller can drive and control the rotary motor 11, the lifting screw motor 24, the first screw motor 42, the second screw motor 52, and the telescopic cylinder 214 to achieve automated control. Furthermore, by connecting the signal output terminal of the proximity switch to the signal input terminal of the controller, when the proximity switch detects the sensing plate on the side of the lifting plate 3, it transmits a signal to the controller. The controller then processes and analyzes the signal to stop the lifting screw motor 24, thereby controlling the range of vertical movement of the lifting plate 3.
