Technical Field

[0001] This invention relates to the field of textile equipment, and more particularly to a textile fabric winding mechanism. Background Technology

[0002] Textile materials are the raw materials for making clothing products. In the production process of textile materials, the winding and guiding operation is an essential processing procedure. In the current winding process of textile materials, due to the relatively soft texture of textile materials, guide rollers are usually used to guide the textile materials during the winding process.

[0060] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0061] like Figure 1 As shown, an embodiment of the present invention provides a textile fabric winding mechanism, wherein the winding assembly includes:

[0062] The first adjustment unit 100 is used to guide the textile fabric. The first adjustment unit 100 includes a first roller 120 and a second roller 130 that are tangent to each other, and a first drive assembly 140 for driving the first roller 120 and the second roller 130 to rotate.

[0063] The winding unit 400 is used to wind up the fabric. When winding up the fabric, the fabric passes between the first roller 120 and the second roller 130 and is wound around the winding unit 400.

[0064] The detection unit 200 is used to detect the degree of fabric offset, and the detection unit 200 is located between the first adjustment unit 100 and the winding unit 400;

[0065] The correction unit 500 is used to push the first adjustment unit 100 to move along the axis of the first roller 120 to correct the fabric;

[0066] The control unit controls the first adjustment unit 100 to move in the opposite direction to the fabric offset direction based on the detection result detected by the detection unit 200.

[0067] In this embodiment, when the fabric is wound up, the fabric passes between the first roller 120 and the second roller 130. Since the first roller 120 and the second roller 130 are tangent to each other, the first roller 120 and the second roller 130 can clamp the fabric when they rotate. The first roller 120 and the second roller 130 rotate in opposite directions. When the control unit detects the fabric offset between the first adjustment unit 100 and the winding unit 400 through the detection unit 200, the control unit controls the correction unit 500 to push the first adjustment unit 100 to move in the opposite direction of the fabric offset to correct the fabric wrapped around the winding unit 400, and prevent the fabric wrapped around the winding unit 400 from offsetting and causing the fabric to fold on the winding unit 400.

[0068] In this embodiment, the first adjustment unit 100 further includes a guide bracket 110, which is U-shaped and has hollow interiors at both ends to accommodate the first drive assembly 140. The first roller 120 and the second roller 130 are rotatably connected to the guide bracket 110 via bushings.

[0069] In some examples, the guide bracket 110 is welded from steel plates;

[0070] like Figure 3As shown, the first drive assembly 140 includes a first gear 141 fixedly connected to the second roller 130, a second gear 142 fixedly connected to the first roller 120, and a drive motor 143 fixedly connected to the guide bracket 110. The first gear 141 meshes with the second gear 142, and the drive motor 143 drives the first gear 141 to rotate. In this embodiment, a worm gear is fixedly connected to the output shaft of the drive motor 143, and a worm wheel is fixedly connected to the first gear 141. The worm gear meshes with the worm wheel, and the worm gear is rotatably connected to the guide bracket 110 via a shaft seat. Inside the bracket 110, when the drive motor 143 is energized and rotates, the drive motor 143 drives the second roller 130 to rotate through the worm gear and worm wheel structure. The second roller 130 drives the first roller 120 to rotate through the first gear 141 and the second gear 142, so that the first roller 120 and the second roller 130 rotate in opposite directions. During the rotation of the first roller 120 and the second roller 130, the fabric passes through the first roller 120 and the second roller 130. The linear velocity of the fabric is the same as the linear velocity of the point on the surface of the first roller 120.

[0071] As a preferred embodiment of this example, Figure 2 As shown, the first roller 120 is also provided with two spiral protrusions with opposite directions of rotation. The connection point of the two spiral protrusions is located in the center of the first roller 120. When the first roller 120 rotates, the spiral protrusions on the first roller 120 spread the fabric to both sides to prevent the fabric from folding.

[0072] As a preferred embodiment of this example, Figure 2 and Figure 3 As shown, the correction unit 500 includes:

[0073] A guide rail 510 is provided at the bottom of the first adjustment unit 100, and the first adjustment unit 100 is slidably connected to the guide rail 510.

[0074] Telescopic component 520, the output shaft of which is fixedly connected to the first adjustment unit 100 to push the first adjustment unit 100 to slide on the guide rail 510;

[0075] In this embodiment, the guide rail 510 is provided with two sets of I-shaped guide rail structures, the bottom of the first adjustment unit 100 is provided with a T-shaped slide groove, the guide bracket 110 slides on the guide rail 510, the telescopic component 520 is a hydraulic telescopic cylinder, and the telescopic shaft of the telescopic component 520 is fixedly connected to the end of the guide bracket 110 through a flange connection structure; when it is necessary to adjust the position of the first adjustment unit 100, hydraulic oil is introduced into the telescopic component 520 or hydraulic oil is extracted from the telescopic component 520 to move the output shaft of the telescopic component 520, thereby pushing the first adjustment unit 100 to slide on the guide rail 510, and the axis of the telescopic component 520 is parallel to the axis of the guide rail 510;

[0076] The control device of the telescopic component 520 is electrically connected to the control unit. For example, when the telescopic component 520 is a hydraulic telescopic cylinder, the control valve of the hydraulic telescopic cylinder is electrically connected to the control unit via a wire network.

[0077] As a preferred embodiment of this example, two telescopic components 520 are provided, and the telescopic components 520 are located at both ends of the first adjustment unit 100 to push the first adjustment unit 100 to move on the guide rail 510. When the first adjustment unit 100 slides on the guide rail 510, the guide rail 510 located at both ends of the first adjustment unit 100 is in a contracted and extended working state, respectively.

[0078] As a preferred embodiment of this example, Figure 4 and Figure 5 As shown, the detection unit 200 includes:

[0079] A light emitter 230 and a light receiver 240 are provided on the upper and lower sides of the fabric. The light emitter 230 and the light receiver 240 are mounted on the detection frame 220 and are used to detect fabric offset.

[0080] The second drive unit 250 is used to drive the light emitter 230 and the light receiver 240 to move in a straight line. The detection frame 220 is mounted on the second drive unit 250. When the light receiver 240 does not receive the light from the light emitter 230, the second drive unit 250 drives the detection frame 220 to move away from the fabric until the light receiver 240 receives the light from the light emitter 230 again.

[0081] A position detection unit 260 is provided on the second drive unit 250 to measure the position of the detection frame 220 on the second drive unit 250 in order to detect the degree of fabric offset.

[0082] In this embodiment, during fabric winding, the detection unit 200 is arranged on both sides of the fabric. The second drive unit 250 controls the movement direction of the light emitter 230 and the light receiver 240 to be perpendicular to the movement direction of the fabric. The positions of the light emitter 230 and the light receiver 240 on the second drive unit 250 are adjusted so that the light emitter 230 and the light receiver 240 are located at the edge of the fabric. When the fabric shifts, the fabric blocks the light emitted by the light emitter 230 in the shift direction. At this time, the second drive unit 250, located in the opposite direction of the shift direction, controls the light emitter 230 and the light receiver 240 to move in the shift direction until the light emitter 230 and the light receiver 240 in the opposite direction of the shift direction are blocked by the fabric. The position detection unit 260, located in the opposite direction of the shift direction, measures the displacement of the light emitter 230 and the light receiver 240 at this time. The control unit collects the displacement of the position detection unit 260 at this time. After measuring the displacement, the control unit pushes the first adjustment unit 100 to move in the opposite direction of the offset direction by the correction unit 500, which is the same distance as the measured displacement. At this time, the fabric is corrected. For example, when the fabric shifts to the left, the light emitted by the light emitter 230 on the left is blocked by the fabric. At this time, the second drive unit 250 on the right pushes the light emitter 230 and the light receiver 240 to the left. The light emitter 230 on the right is just blocked by the fabric, that is, the light receiver 240 on the right cannot receive the light emitted by the light emitter 230. At this moment, the position detection unit 260 on the right measures the displacement of the light emitter 230 and the light receiver 240 and sends it to the control unit. The control unit controls the output shaft of the telescopic component 520 on the left to extend and the output shaft of the telescopic component 520 on the right to retract, so that the first adjustment unit 100 moves to the right by the same distance as the displacement of the light emitter 230 and the light receiver 240. At this time, the fabric is corrected.

[0083] In this embodiment, when the drive unit 250 drives the detection frame 220 to move, it controls the movement of the detection frame 220 by receiving a signal from the control unit.

[0084] In this embodiment, the adjustment method for the light emitter 230 and the light receiver 240 is as follows: the second driving unit 250 drives the light emitter 230 and the light receiver 240 to move closer to the fabric until the fabric is located between the light emitter 230 and the light receiver 240. Then, the light emitter 230 and the light receiver 240 are controlled to move away from the fabric until the light receiver 240 just receives the light from the light emitter 230. The movement of the light emitter 230 and the light receiver 240 is stopped. At this time, the light emitter 230 and the light receiver 240 are located at the edge of the fabric.

[0085] In a preferred embodiment of this invention, the second drive unit 250 is a lead screw drive mechanism. The light emitter 230 and the light receiver 240 are mounted on the second drive unit 250 via a detection frame 220. The detection frame 220 is F-shaped, with the light emitter 230 and the light receiver 240 respectively mounted on the two horizontal ends of the F-shape. The vertical end of the F-shape is mounted on the second drive unit 250. The second drive unit 250 drives the detection frame 220 to move, thereby moving the light emitter 230 and the light receiver 240.

[0086] In this embodiment, as Figure 5 As shown, the detection unit 200 includes a base 210, and the second drive unit 250 includes a first motor 251, a lead screw 252, and a guide rod 253. The first motor 251 is fixed to the base 210 by screws, the lead screw 252 is rotatably connected to the base 210 by a bearing structure, and the output shaft of the lead screw 252 is fixedly connected to the output shaft of the first motor 251 by a coupling. The guide rod 253 is fixedly connected to the base 210 by a bearing structure. The detection frame 220 is fixedly connected to a lead screw nut 254 and a linear bearing 255 by welding. The guide rod 253 is threaded to the lead screw 252, and the linear bearing 255 is slidably connected to the guide rod 253. When the first motor 251 is energized and rotates, the first motor 251 drives the lead screw 252 to rotate, thereby driving the detection frame 220 to slide on the guide rod 253, thereby driving the detection frame 220 to move in a straight line.

[0087] As a preferred embodiment of this example, Figure 5 and Figure 6As shown, the position detection unit 260 includes a first resistance bar 261 and a second resistance bar 262 arranged in parallel, a conductive block 263 in contact with the first resistance bar 261 and the second resistance bar 262, and a resistance testing circuit. The resistance testing circuit is electrically connected to the first resistance bar 261 and the second resistance bar 262 to test the resistance connected to the resistance testing circuit. The conductive block 263 is fixedly connected to the detection frame 220 to move with the detection frame 220. The first resistance bar 261 and the second resistance bar 262 are parallel to the moving trajectory of the detection frame 220. When the detection frame 220 moves the conductive block 263, the conductive block 263 slides on the first resistance bar 261 and the second resistance bar 262, thereby changing the resistance value of the first resistance bar 261 and the second resistance bar 262 connected to the resistance testing circuit, thereby detecting the moving distance of the detection frame 220 based on the change in resistance value.

[0088] Preferred, such as Figure 7 As shown, the conductive block 263 is U-shaped, and its two ends are in contact with the first resistor strip 261 and the second resistor strip 262. The position detection unit 260 also includes a limiting box 264 and a compression spring 265 disposed within the limiting box 264. The limiting box 264 is a cylindrical structure with an opening at one end. A limiting cover 266 is fixedly connected to the opening of the limiting box 264 to close the opening. The end of the conductive block 263 passes through the conductive block 263 and is slidably connected to it. Inside, the two ends of the compression spring 265 abut against the limiting cover 266 and the conductive block 263 respectively to compress the conductive block 263 into contact with the first resistance strip 261 and the second resistance strip 262. The limiting box 264 is fixedly connected to the detection frame 220 by screws. In this embodiment, the setting of the limiting box 264 and the compression spring 265 ensures that the conductive block 263 is always in contact with the first resistance strip 261 and the second resistance strip 262, thereby preventing poor contact after the conductive block 263 wears down.

[0089] As a preferred embodiment of this example, Figure 8 and Figure 9As shown, the take-up unit 400 includes a take-up base 410, a take-up arm 420 hinged to the take-up base 410, a third drive unit 450 fixedly connected to the take-up base 410, and a telescopic support 430 with its two ends respectively hinged to the take-up arm 420 and the take-up base 410. A roller frame 440 is rotatably connected to one end of the take-up arm 420 away from the take-up base 410. The take-up base 410, take-up arm 420, telescopic support 430, and roller frame 440 together form a roller support to support the take-up roller 460. Two sets of roller supports are provided, located at both ends of the take-up roller 460. The roller frame 440 is used to fix the take-up roller 460. 0. The third drive unit 450 is provided, and the third drive unit 450 is mounted on one of the take-up seats 410. The third drive unit 450 is connected to the roller frame 440 to drive the roller frame 440 to rotate. The output shaft of the telescopic support 430 is hinged to the take-up arm 420. The end of the telescopic support 430 away from the take-up arm 420 is hinged to the take-up seat 410. The take-up seat 410, the take-up arm 420 and the telescopic support 430 form a triangular structure. The telescopic support 430 is used to drive the take-up arm 420 to rotate on the take-up seat 410 to load and unload the take-up roller 460.

[0090] In this embodiment, the telescopic support 430 is controlled to retract on the take-up roller 460, causing the end of the take-up arm 420 away from the take-up seat 410 to rotate toward the ground. When the take-up arm 420 descends to the required height, the retraction of the telescopic support 430 is stopped, and the end of the take-up roller 460 is fixed to the roller frame 440. Then, the telescopic support 430 is controlled to extend, and after the telescopic support 430 reaches the preset height, one end of the fabric is fixedly connected to the take-up roller 460 to start taking up the fabric.

[0091] In this embodiment, as Figure 10As shown, the take-up base 410 is an L-shaped block. One end of the take-up arm 420 is hinged to the short end of the take-up base 410 via a bearing. The third drive unit 450 includes a second motor 451 and a first pulley 452. The second motor 451 is fixedly connected to the short end of the third drive unit 450 by screws. The output shaft of the second motor 451 passes through the rotating shaft of the take-up arm 420 and is fixedly connected to the first pulley 452. A bearing is provided between the rotating shaft of the take-up arm 420 and the output shaft of the second motor 451. The two ends of the telescopic support 430 are connected to the take-up base 410 and the take-up arm 420 via pins. The roller frame 440 includes a fixed part 441 and a movable part 442. The fixed part 441 is rotatably connected to the take-up arm 420 away from the take-up base 410. The fixed part 441 is fixedly connected to a second pulley 453. The first pulley 452 and the second pulley 453 are connected by a belt 454. The fixed part 441 is provided with a first fixing groove 443. The movable part 442 has a tile-shaped structure and a second fixing groove 444. When the movable part 442 is installed on the fixed part 441, the first fixing groove 443 and the second fixing groove 444 form a regular polygonal hole. The two ends of the take-up roller 460 are regular polygonal prism structures. When the take-up roller 460 is installed on the roller frame 440, the first fixing groove 443 and the second fixing groove 444 clamp the take-up roller 460 to fix the take-up roller 460. In some examples, the fixed part 441 and the movable part 442 are fixedly connected by bolts.

[0092] like Figure 10 As shown, the take-up arm 420 is a rod-shaped structure. A first rotating shaft 421 is provided at one end of the take-up arm 420 connected to the take-up base 410. The first rotating shaft 421 is rotatably connected inside the take-up base 410. A bracket mounting hole 422 is provided at the end of the take-up arm 420 away from the take-up base 410. The roller frame 440 is rotatably connected to the bracket mounting hole 422. A second rotating shaft 423 is provided between the first rotating shaft 421 and the bracket mounting hole 422. The second rotating shaft 423 is used to connect the telescopic support 430.

[0093] In some examples, the first pulley 452 and the second pulley 453 are both belt pulleys, and the belt 454 is a V-belt.

[0094] As a further embodiment of the present invention, a second adjustment unit 300 is also provided between the detection unit 200 and the winding unit 400. The structure of the second adjustment unit 300 is the same as that of the first adjustment unit 100. It is used to prevent the fabric from shifting and causing wrinkles on the winding unit 400. When the fabric shifts, it will first shift on the first adjustment unit 100. When the shifted area is transmitted to the second adjustment unit 300, the detection unit 200 will detect the fabric shift. At this time, the correction unit 500 will immediately correct the fabric shift. The shifted part is corrected before it is transmitted to the winding unit 400, thereby preventing wrinkles from forming on the winding unit 400.
