Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically a fabric winding machine for garment production. Background Technology

[0002] A fabric winding machine is a mechanical device used to neatly wind continuously produced fabrics or other flexible materials into rolls. It is widely used in the textile, printing and dyeing, and packaging industries.

[0003] For example, Chinese patent CN206437672U discloses a fabric winding machine. The key technical features include a frame and a winding roller. The frame is provided with an infeed section, which includes a support plate and upper rollers on both sides of the support plate. The axis of the rollers is parallel to the feeding direction of the support plate, and the rollers on both sides rotate outward from the support plate. A soft wool sleeve is fitted on the roller, and the bottom of the soft wool sleeve abuts against the support plate. The rollers provide an outward force to both sides of the fabric, making it less prone to wrinkles when the fabric is wound up.

[0004] During operation, existing fabric winding machines often experience lateral displacement and edge wrinkles due to mechanical vibration or uneven traction, which affects the neatness of winding and reduces the pass rate. In addition, upstream tension fluctuations can cause fine wrinkles, further damaging the fabric quality. Summary of the Invention

[0005] The purpose of this utility model is to provide a fabric winding machine for garment production, so as to solve the problems in the above-mentioned background technology where lateral displacement and edge wrinkles occur due to mechanical vibration or uneven traction, which affect the winding neatness and reduce the pass rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric winding machine for garment production, comprising a first support and a second support, wherein the first support and the second support are connected to each other to form a base; An adjustment structure is installed on the top of the first bracket. The adjustment structure includes a transport roller and a splined shaft installed on the top of the first bracket. Both the transport roller and the splined shaft are installed on the top of the first bracket through bearing seats. An adjustment roller is slidably connected to the outside of the splined shaft. A fixed frame is fixedly connected to the top of the first bracket. The fixed frame is located between the transport roller and the adjustment roller. Equally spaced laser emitters are fixedly connected to the bottom of the inner side of the fixed frame. Equally spaced laser receivers corresponding to the laser emitters are fixedly connected to the top of the inner side of the fixed frame.

[0007] Preferably, the length direction of the transport roller, spline shaft, adjusting roller, and fixed frame, as well as the sliding direction of the adjusting roller, are all perpendicular to the movement direction of the fabric, and an adjusting plate is installed at the bottom of the first bracket.

[0008] Preferably, both ends of the adjusting plate are rotatably connected to the outer sides of both ends of the adjusting roller, and a telescopic rod is fixedly connected to the bottom of the first bracket, with the telescopic end of the telescopic rod connected to the adjusting plate.

[0009] Preferably, a support frame is fixedly connected to the top of the connection between the first bracket and the second bracket, and an adjusting rod is slidably connected inside the support frame, with the adjusting rod being arranged parallel to the support frame.

[0010] Preferably, pressure rollers are rotatably connected to both ends of the bottom of the adjusting rod, and an adjusting screw is threadedly connected to the middle of the support frame, with the lower end of the adjusting screw rotatably connected to the middle of the adjusting rod.

[0011] Preferably, the top of the second bracket has two parallel winding rollers rotatably connected via bearing seats. One end of each winding roller is fixedly connected to a driven gear. The bottom of the second bracket is rotatably connected to a driving gear driven by a motor, and the driving gear meshes with the two driven gears.

[0012] Preferably, a sliding rod is fixedly connected in the middle of the second bracket, and two symmetrically distributed limiting plates are slidably connected to the outside of the sliding rod. The limiting plates are located between the two take-up rollers, and a reverse screw is rotatably connected to the bottom of the second bracket through a bearing seat. The reverse screw is threaded to the lower end of the two limiting plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This fabric winding machine for garment production detects the fabric position through a laser emitter and receiver array within a fixed frame, generates a deviation signal, and drives a telescopic rod to rotate an adjusting plate. This causes the adjusting roller to slide along the spline shaft, changing the fabric wrap angle. This allows for dynamic adjustment of the lateral position during fabric transport, avoiding delays caused by manual intervention and improving correction efficiency and accuracy.

[0014] The sliding connection structure between the spline shaft and the adjusting roller ensures no circumferential displacement. When the adjusting roller moves based on the correction signal, the key design of the spline shaft restricts its rotational freedom, allowing the adjusting roller to translate only in the sliding direction. This prevents the fabric from being deformed or damaged due to torsion during the correction process, thus maintaining the flatness and mechanical stability of the fabric.

[0015] The adjusting rod is driven to move vertically by rotating the adjusting screw connected to the internal thread of the support frame. This drives the pressure roller at the bottom to apply precise pressure to the fabric, achieving flexible pressing of the fabric. It can be finely adjusted for different tension fluctuations to eliminate minor wrinkles caused by upstream pressure. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example 1: Please refer to Figure 1 - Figure 4 The present invention provides the following technical solution: like Figure 1 As shown, a fabric winding machine for garment production includes a first support 1 and a second support 2, which are connected to each other to form a base; Figure 2 and Figure 3 As shown, an adjustment structure is installed on the top of the first support 1. The adjustment structure includes a transport roller 3 and a splined shaft 4 installed on the top of the first support 1. Both the transport roller 3 and the splined shaft 4 are installed on the top of the first support 1 through bearing seats. An adjustment roller 5 is slidably connected to the outside of the splined shaft 4. A fixed frame 8 is fixedly connected to the top of the first support 1. The fixed frame 8 is located between the transport roller 3 and the adjustment roller 5. Laser emitters 9 are fixedly connected at equal intervals to the bottom of the inner side of the fixed frame 8. Laser receivers corresponding to the laser emitters 9 are fixedly connected at equal intervals to the top of the inner side of the fixed frame 8.

[0020] like Figure 4As shown, the length direction of the transport roller 3, spline shaft 4, adjusting roller 5, and fixed frame 8, as well as the sliding direction of the adjusting roller 5, are all perpendicular to the direction of fabric movement. An adjusting plate 6 is installed at the bottom of the first bracket 1. Both ends of the adjusting plate 6 are rotatably connected to the outer sides of both ends of the adjusting roller 5. A telescopic rod 7 is fixedly connected to the bottom of the first bracket 1, and the telescopic end of the telescopic rod 7 is connected to the adjusting plate 6.

[0021] The transport roller 3 is fixed to the top of the first bracket 1 by bearing seats at both ends. Its rotation is driven by an external transmission mechanism to pull the fabric at a constant speed. At this time, the fabric is in a taut state and moves forward horizontally, with its width direction parallel to the roller axis.

[0022] The laser emitters 9, which are equidistantly arranged on the bottom inner side of the fixed frame 8, emit light beams upwards. The corresponding laser receivers at the top receive the light signals in real time. When the fabric shifts laterally or wrinkles at the edge, part of the light beam is blocked, causing the receiver signal strength to decrease. For example, moving the fabric to the left will block the left-side light beam. This signal change generates a position deviation signal through the control circuit.

[0023] The detection signal immediately drives the adjustment system: the telescopic rod 7 moves according to the direction of the deviation. When it deviates to the left, its telescopic end retracts, causing the adjustment plate 6 to rotate counterclockwise. Since the two ends of the adjustment plate 6 are rotatably connected to the journal of the adjustment roller 5, the adjustment roller 5 slides to the left along the spline shaft 4. At this time, the fabric forms a larger wrap angle on the left side of the adjustment roller 5, generating a lateral force to the right to correct the deviation. This adjustment process continues until the laser signal returns to normal, realizing closed-loop control. The keyed structure of the spline shaft 4 ensures that there is no circumferential displacement when the adjustment roller 5 moves, avoiding twisting and deformation of the fabric.

[0024] Example 2: Based on Example 1, please refer to... Figure 4 - Figure 6 The following structure was also disclosed: like Figure 4 and Figure 5 As shown, a support frame 10 is fixedly connected to the top of the connection between the first bracket 1 and the second bracket 2. An adjusting rod 11 is slidably connected inside the support frame 10. The adjusting rod 11 is set parallel to the support frame 10. Pressure rollers 13 are rotatably connected to both ends of the bottom of the adjusting rod 11. An adjusting screw 12 is threadedly connected to the middle of the support frame 10. The lower end of the adjusting screw 12 is rotatably connected to the middle of the adjusting rod 11.

[0025] like Figure 5 and Figure 6As shown, the top of the second bracket 2 is rotatably connected to two parallel winding rollers 14 via bearing seats. One end of the winding roller 14 is fixedly connected to a driven gear 15. The bottom of the second bracket 2 is rotatably connected to a driving gear 16 driven by a motor, which meshes with the two driven gears 15. A slide rod is fixedly connected in the middle of the second bracket 2. Two symmetrically distributed limiting plates 18 are slidably connected to the outside of the slide rod. The limiting plates 18 are located between the two winding rollers 14. The bottom of the second bracket 2 is rotatably connected to a reverse screw 17 via bearing seats. The reverse screw 17 is threaded to the lower end of the two limiting plates 18.

[0026] When the corrected fabric enters the support frame 10 area, the pressure roller 13 at the bottom of the adjusting rod 11 applies vertical pressure to the fabric. Rotating the adjusting screw 12 can change the vertical position of the adjusting rod 11 in the support frame 10: when rotated clockwise, the screw 12 pushes the adjusting rod 11 down, increasing the pressing force of the pressure roller 13 and eliminating the fine wrinkles caused by upstream tension fluctuations.

[0027] The motor drives the drive gear 16 to rotate the two driven gears 15 in the same direction, causing the two take-up rollers 14 to rotate in the same direction at the same speed. During the fabric winding process, the paper tube is placed between the two take-up rollers 14, and the limiting plate 18 physically constrains the two ends of the paper tube. When the lead screw 17 rotates, the two limiting plates 18 move synchronously towards or away from each other along the slide bar to adapt to different widths of fabric and position the paper tube of the fabric being wound in the middle of the two take-up rollers 14.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
