Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile equipment, in particular to a winding device and winding method for a cloth pre-shrinking machine. BACKGROUND

[0002] In the field of textile processing, after the cloth pre-shrinking treatment, the cloth needs to be regularly wound by a winding device for subsequent storage, transportation and deep processing. The performance of the winding device directly affects the quality of the cloth product and the production efficiency. At present, the winding devices matched with the existing cloth pre-shrinking machines generally have the following technical defects, which are difficult to meet the production requirements of high quality and high efficiency: The feeding guide structure of the existing winding device is mostly fixedly arranged, and the installation position of the guide roller is not adjustable, which can only adapt to cloth of a single specification (width and thickness). When processing different types of cloth, the fixed conveying path is easy to cause unreasonable extrusion or stretching between the cloth and the guide roller, and even the cloth may be jammed or deviated, which not only affects the conveying stability, but also may cause damage to the surface of the cloth.

[0003] Most of the cloth swinging mechanisms adopt a single driving structure, and the swinging track precision is low, and the cloth swinging mechanism cannot form precise cooperation with the winding action. At the same time, most of the cloth swinging mechanisms do not integrate a targeted tension adjusting and cloth flattening structure, so that the cloth is easy to have uneven tension and wrinkle accumulation during the winding process, and the cloth is unevenly distributed on the winding roller, which is easy to form irregularly wound roll of "single-thick and single-thin", and the roll needs to be additionally arranged when it is used later, which increases the processing cost.

[0004] The driving assembly and the winding roller of the existing winding device are mostly rigidly connected, and when the winding roller has a slight position deviation or needs to be replaced, the entire driving structure needs to be disassembled, which is complicated to operate and seriously affects the production continuity. In addition, the structure design of the winding trolley is unreasonable, the moving flexibility is poor, the transfer efficiency of the wound roll after winding is low, and the overall production efficiency is further restricted.

[0005] The support frame of part of the winding device is simply designed and does not have a reasonable reinforcing and positioning structure, which is easy to vibrate during long-term high-speed operation, which not only aggravates the wear of the components, but also may cause the deviation of the cloth conveying track, affecting the winding precision. At the same time, the connection reliability of the frame and each functional component is poor, and problems such as looseness and abnormal noise are easy to occur, increasing the equipment maintenance cost.

One end of the tension center rod 241 extends out of the outer side wall of the swing arm plate 231 and is fixedly connected to the first driven gear 2453. The gear belt 2454 is sleeved on the outside of the first drive gear 2452 and the first driven gear 2453.

[0035] Specifically, the output shaft of potentiometer 2451 drives the drive gear to rotate, which in turn drives the driven gear fixed to the end of tension center rod 241 to rotate synchronously via gear belt 2454. This drives tension center rod 241 and the connected tension swing arm plate 243 and tension roller 242 to achieve precise angle adjustment. At the same time, potentiometer 2451 can provide real-time feedback on the rotation angle of tension center rod 241, forming a closed-loop control of the position of tension roller 242. This transmission structure has a stable transmission ratio and precise response, and can adaptively adjust the posture of tension roller 242 according to changes in fabric tension, further improving the accuracy and timeliness of fabric tension control. This avoids problems such as stretching deformation, loosening and deviation of the fabric due to tension imbalance, ensuring the stability of fabric conveying and winding.

[0036] Specifically, please refer to Figure 7 , 8 As shown, in one embodiment of the present invention, the opening roller assembly 25 includes an opening roller 251, a pre-reduction speed reducer 252, and a pre-reduction drive motor 253. The opening roller 251 is rotatably mounted on the swing arm plate 231 via a second bearing seat 2511. The pre-reduction speed reducer 252 is mounted on the outer side wall of the swing arm plate 231 via a speed reducer fixing plate 2521 and a speed reducer fixing rod 2522. The input shaft of the pre-reduction speed reducer 252 is connected to the output shaft of the pre-reduction drive motor 253, and the output shaft of the pre-reduction speed reducer 252 is connected to the rotating shaft of the opening roller 251.

[0037] The pre-shrinking speed reducer 252 is securely installed on the outer wall of the swing arm plate 231 by the speed reducer fixing plate 2521 and the speed reducer fixing rod 2522, ensuring the stability and rigidity of power transmission. The pre-shrinking drive motor 253 drives the opening roller 251 to rotate after being reduced and increased in torque by the speed reducer. It can apply uniform and controllable opening tension to the passing fabric, effectively eliminating the transverse wrinkles generated by the fabric during washing and conveying. At the same time, the opening roller 251 swings synchronously with the swing arm plate 231, which can adapt to the posture of the fabric under different tension conditions, further improving the flatness and stretching effect of the fabric, and laying a good foundation for subsequent high-precision winding.

[0038] Specifically, please refer to Figure 9 As shown, in one embodiment of the present invention, the bottom of the trolley connecting frame 31 is provided with casters, and the two ends of the winding roller 32 are rotatably supported on the top of the trolley connecting frame 31 by bearings.

[0039] In this embodiment, the bottom of the trolley connecting frame 31 of the winding trolley 3 is equipped with casters. The winding roller 32 is supported at both ends by bearings on the top of the trolley connecting frame 31. This design allows the winding trolley 3 to move flexibly through the casters, making it easy to adjust the winding position according to the fabric winding requirements and adapt to the winding operation of different specifications of fabric. At the same time, the rotation support of the bearings ensures the smooth rotation of the winding roller 32, reduces frictional resistance during the winding process, and avoids problems such as stretching, wrinkling or irregular winding of the fabric due to the roller's poor rotation. This improves the convenience and quality of the fabric winding operation.

[0040] Specifically, please refer to Figure 10 As shown, in one embodiment of the present invention, the telescopic universal joint 41 includes a universal joint head 413 and a first connecting joint head 411 and a second connecting joint head 412 connected to both ends of the universal joint head 413. The first connecting joint head 411 is adapted to be connected to the rotating sleeve of the take-up drum 32, and the second connecting joint head 412 is adapted to be fixedly connected to the output shaft of the rotary reducer 42.

[0041] In this embodiment, the telescopic universal joint 41 adopts a telescopic linkage structure with a universal joint head 413 and splined connecting joints at both ends. The first extended spline shaft 4111 of the first connecting joint head 411 is adapted to the rotating sleeve of the winding drum 32, and the first hollow spline bushing 4121 of the second connecting joint head 412 is fixed to the output shaft of the rotary reducer 42. Combined with the telescopic cooperation of the sliding rod 4131 and the sliding sleeve 4132 built into the universal joint head 413, it can ensure the stability and continuity of the power transmission from the rotary reducer 42 to the winding drum 32, and can also accommodate the displacement deviation caused by the position adjustment of the winding carriage 3. At the same time, the structure of the first spring 41121 and the first sleeve 41122 in the first clamp head 4112 and the structure of the second spring 41221 and the second sleeve 41222 in the first hollow clamp head 4122 can buffer the impact during the power transmission process, avoid the fabric winding tension fluctuation caused by transmission vibration, and further improve the accuracy and reliability of the winding operation.

[0042] Please see Figure 11 As shown, another embodiment of the present invention also provides a winding method based on the above-described fabric pre-shrinking machine winding device, the winding method comprising the following steps: S1: Path adaptation By adjusting the side linkage structure 131 of the front frame 1 of the flat-width washing machine, the rotating rod component 132 is driven to move in tandem, and the conveying path of the fabric is adjusted in conjunction with the horizontal rotating roller assembly 12. S2: Tension Adjustment The fabric passes through the adjusting roller assembly 13 and the horizontal rotating roller assembly 12 in sequence and enters the fabric spreading mechanism 2. The tension roller assembly 24 adjusts the fabric tension in real time through the cooperation of the tension swing arm plate 243 and the second proximity switch 244. S3: Open layout The pre-shrink drive motor 253 drives the opening roller 251 to rotate and flatten the fabric. The first drive cylinder 211 drives the swing core assembly 21 to drive the swing arm assembly 23 to swing back and forth, so that the fabric is evenly distributed on the take-up roller 32. S4: Synchronous winding The rotary reducer 42 drives the take-up roller 32 to rotate through the telescopic universal joint 41, which is synchronized with the swing speed of the fabric swaying mechanism 2 to complete the fabric take-up.

[0043] The fabric pre-shrinking machine winding method in this embodiment of the invention operates through a four-step progressive process: path adaptation, tension control, fabric spreading, and synchronous winding. First, the fabric conveying path is adjusted by the linkage between the side connecting rod structure and the rotating rod component to ensure stable fabric conveying posture. Then, the fabric tension is controlled in real time by the cooperation of the tension roller assembly 24 and the second proximity switch 244 to prevent the fabric from becoming loose or stretched. Subsequently, the active flattening of the spreading roller 251 and the reciprocating swing of the swing arm assembly 23 are used to eliminate fabric wrinkles and achieve uniform distribution of the fabric on the winding drum. Finally, the power is transmitted through the telescopic universal joint 41 to precisely synchronize the rotation speed of the winding drum 32 with the swing speed of the swing arm, realizing full automation and high-precision control of the fabric from conveying to winding, effectively improving the quality and efficiency of fabric winding and reducing fabric loss during the winding process.

Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this invention.
