[0001] This utility model relates to the field of nonwoven fabric processing equipment, and in particular to a nonwoven fabric winding device for nonwoven fabric processing. Background Technology

[0002] In the field of nonwoven fabric processing, the winding device is one of the core pieces of equipment in the production line, and its performance directly affects the winding quality and production efficiency of the nonwoven fabric. However, during the winding process, traditional nonwoven fabric winding devices are prone to uneven fabric tension or design defects in the guiding mechanism, resulting in uneven edges and loose winding due to wrinkles. Furthermore, they cannot adapt to the dynamic adjustment needs of nonwoven fabrics of different thicknesses.

[0003] Therefore, there is an urgent need for a nonwoven fabric winding device that can smooth out the feed end of the nonwoven fabric during the winding process. Utility Model Content

[0004] Therefore, to address the aforementioned problems, this utility model proposes a nonwoven fabric winding device for nonwoven fabric processing. It solves the technical problem of uneven edges and loose winding of the nonwoven fabric caused by wrinkles during the winding process.

Detailed Implementation

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] refer to Figure 1 - Figure 5 This embodiment provides a nonwoven fabric winding device for nonwoven fabric processing, the structure of which includes the following technical solution: a machine body 1, a winding roller 2 installed inside the machine body 1, a feeding roller 3 for conveying nonwoven fabric, and a flattening component 4 installed in front of the winding end of the winding roller 2. The flattening component 4 includes drive frames 41 installed on both sides of the inner wall of the machine body 1, a working frame 42 is provided between the two drive frames 41, fixed seats 43 are symmetrically installed on the upper surface of the drive frames 41, and an adjusting rod 44 is installed between the left and right fixed seats 43. The two ends of the adjusting rod 44 are fitted with positioning parts 45 with a clearance fit. The positioning parts 45 are located on the upper surface of the working frame 42. A rectangular groove is opened in the middle of the working frame 42. At least two sets of flattening rollers 46 rotating in opposite directions to the outside are installed inside the rectangular groove. In this embodiment, two sets of flattening rollers 46 rotating in opposite directions to the outside are used. The specific installation can be adjusted according to the actual situation.

[0022] The drive frame 41 is equipped with a drive motor, which is connected to the worm gear 462.

[0023] It should be noted that the drive motor installed inside the drive frame 41 is a conventional component in this field. A single-phase asynchronous motor of model 5IK120RGN-CF can be selected, which can provide stable and sufficient power to the worm gear. The worm gear and gear are conventional mechanical transmission components, made of 45 steel, which has been hardened to improve its hardness and wear resistance, ensuring the stability and reliability of the transmission. As long as the drive motor, worm gear and gear can achieve the above-mentioned desired effect, other models can be replaced according to the actual working conditions.

[0024] Two sets of smoothing rollers 46 are each provided with at least three rollers and are arranged at equal intervals. The surface of the smoothing rollers 46 is provided with threaded texture, which is used to flatten the non-woven fabric in contact with them when rotating. One end of the smoothing rollers 46 is connected to the worm gear 462 in the drive frame 41 through the gear 461, and the other end is installed on the inner wall of the working frame 42 through the movable support. There are two worm gears 462 in total, which are connected to the gear 461 of each set of smoothing rollers 46 respectively. Each worm gear 462 is connected to the drive frame 41 on both sides respectively.

[0025] According to the above component settings, when the nonwoven fabric enters the flattening assembly 4, the drive motor drives the worm gear 462 to rotate. The worm gear 462 drives the flattening roller 46 to rotate through the gear 461. In conjunction with the thread pattern on the surface of the flattening roller 46, the multiple flattening rollers 46 arranged at equal intervals flatten the nonwoven fabric from different positions and angles, thereby eliminating the wrinkles on the surface of the nonwoven fabric and allowing the nonwoven fabric to enter the winding roller 2 in a flat state for winding.

[0026] It should be noted that when the smoothing roller 46 comes into contact with the nonwoven fabric, the smoothing roller 46 rotates. Utilizing the threaded texture on the surface of the smoothing roller 46, the smoothing roller 46 uses friction to flatten the nonwoven fabric to both sides.

[0027] The flattening operation of the smoothing roller 46 and the nonwoven fabric can also be achieved by setting a camera on it to capture images and identify whether the nonwoven fabric is wrinkled. When wrinkles are detected on the surface of the nonwoven fabric, the smoothing roller 46 is controlled to rotate to flatten the surface of the nonwoven fabric. After the surface of the nonwoven fabric is flattened, the smoothing roller 46 is controlled to stop rotating.

[0028] The adjusting rod 44 has multiple positioning holes 441 on its surface for fixing the positioning component 45. The positioning component 45 includes a right-angle plate 451 and a movable and detachable pad 452 inside the right-angle plate 451. The pad 452 is made of rubber and has a cotton layer on its outer surface. A movable block 453 that is in contact with the adjusting rod 44 is installed on the upper surface of the right-angle plate 451. A through hole is opened on the upper surface of the movable block 453, and a positioning rod 454 is inserted through the through hole. The end of the positioning rod 454 passes through the through hole and extends into the positioning hole 441. A spring ring 455 connected to the upper surface of the movable block 453 is fitted on the outer surface of the positioning rod 454.

[0029] In practical use, when winding nonwoven fabrics of different widths, the position of the right-angle plate 451 is adjusted to allow the right-angle plate 451 and the padding layer 452 to move to a suitable position according to the width of the nonwoven fabric, thus pressing the edges of the nonwoven fabric together. The overall installation height, pressure force, or clearance of the nonwoven fabric can be adjusted according to actual operation. The positioning component 45 is mainly used to assist in the positioning and movement of the two edges of the nonwoven fabric. By adjusting the positioning hole 441 on the surface of the adjusting rod 44, the positioning rod 454 and the spring ring 455 are pulled upward, separating the positioning rod 454 from the movable block 453 and the positioning hole 441. Then, the positioning rod 454, the right-angle plate 451, and the movable block 453 move to a suitable position, thereby enabling the right-angle plate 451 and the padding layer 452 to play a role in auxiliary fixing the edges of the nonwoven fabric.

[0030] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
