There are four conveying rollers 108, and every two are arranged in parallel at a relatively equidistant distance. After the staff installs the winding roller 3, one end of the non-woven fabric scraps passes through the top of the guide frame 107, so that the non-woven fabric scraps are between the two pairs of conveying rollers 108, and the non-woven fabric scraps are One end of the material is limited at the outer ring of the winding roller 3, and the servo motor 2 and the lead screw slide 106 are turned on, so that the servo motor 2 drives the winding roller 3 to rotate and wind up the non-woven fabric scraps, and drives the non-woven fabric scraps to pass through the guide frame 107 and guide between the conveying rollers 108 for limited guidance. At the same time, the lead screw slide 106 drives the guide frame 107 to slide repeatedly left and right on the inside of the slide rail 105 through the slider, so that the non-woven fabric scraps are evenly wound and processed on the outside of the winding roller 3, which can avoid the non-woven fabric scraps from being wound up due to disorder, and it is inconvenient to remove the non-woven fabric corners from the winding roller 3, thereby improving the effect of uniform winding processing of the non-woven fabric corners.

[0028] Reference Figure 1 , 2 , 4, 5, further, the pressing and anti-loosening mechanism is composed of a groove 302, a slide groove C303, a limit card slot 304, an adjustment pressure plate 305, a damping telescopic rod B306, a pressure plate 307 and a limit card frame B308;

[0029] The outer ring of the winding roller 3 is embedded with a groove 302, and the inner wall of the groove 302 is embedded with a slide groove C303. An adjusting pressure plate 305 is provided on the inner side of the slide groove C303 close to the groove 302 through a sliding block. Damping telescopic rods B306 are fixedly installed on both sides below the adjusting pressure plate 305, and a spring is provided on the outer side of the damping telescopic rod B306. A pressure plate 307 is fixedly installed between the ends of the damping telescopic rod B306, and the lower surface of the pressure plate 307 and the lower surface of the inner wall of the groove 302 are both wavy.

When the staff passes the non-woven fabric corners from above the guide frame 107 so that the non-woven fabric corners are between the two pairs of conveying rollers 108, the staff pushes the limit bracket B308 rotates through the bearing, rotates from the inside of the limit slot 304 to release the adjusting pressure plate 305, pushes the adjusting pressure plate 305 upward, and places one end of the non-woven fabric scrap under the pressure plate 307, pushes the adjusting pressure plate 305 downward to slide laterally inside the slide groove C303 through the slider, so that the pressure plate 307 squeezes and contacts the upper surface of the non-woven fabric scrap, and fits and contacts with the lower surface of the wavy inner wall of the groove 302, while clamping the non-woven fabric scrap, squeezing the damping telescopic rod B306 and the outer spring to contract, driving After the limit bracket B308 slides into the limit slot 304 and is rotated to completely fit the inside of the limit slot 304, the contracted damping telescopic rod B306 and the outer spring generate a reverse thrust on the pressure plate 307. After the non-woven fabric scraps are stably pressed and fixed, when the staff turns on the servo motor 2 to drive the winding roller 3 to collect and process the non-woven fabric scraps, the loosening of the non-woven fabric scraps on the outer circle of the winding roller 3 can be avoided, which makes it inconvenient to wind them up, thereby improving the effect of stabilizing the pressing and preventing loosening of the non-woven fabric scraps during winding.

[0030] Reference Figure 2 Furthermore, the electric telescopic rod 101, the screw guide rail 106 and the servo motor 2 are all electrically connected to the battery through the control panel of the winding frame 1.

[0031] Embodiment 2:

The pressure plate 305 slides laterally inside the slide groove C303 through the slider, so that the pressure plate 307 is squeezed and contacts the upper surface of the non-woven fabric scraps, and fits and contacts with the lower surface of the wavy inner wall of the groove 302, while limiting and clamping the non-woven fabric scraps, the damping telescopic rod B306 and the outer spring are squeezed to contract, driving the limit bracket B308 to slide into the limit bracket groove 304, and after rotating the limit bracket B308 half a circle, the adjustment pressure plate 305 is released, so that the damping telescopic rod B306 and the outer spring drive the adjustment pressure plate 305 to rebound upward a small distance, so that the limit bracket B308 completely slides into the inner side of the limit bracket groove 304 and fits more firmly. After the limit is limited, the contracted damping telescopic rod B306 and the outer spring generate a reverse thrust on the pressure plate 307, and the non-woven fabric scraps are stably pressed and fixed. Compared with the first embodiment, the stable limiting effect is better.

[0033] Working principle: First, when the staff needs to collect and process the scraps after cutting the cloth, the staff moves the winding frame 1 to the work site through the universal wheel 103, and controls the electric telescopic rod 101 to lower the support plate 102 to contact the ground to support the winding frame 1. Then, the staff places the winding roller 3 to be used between the mounting bracket A201 and the mounting bracket B202, and pushes the two limit brackets A204 on the side of the mounting bracket A201 to drive the damping telescopic rod A205 and the outer spring to contract, and then places one end of the winding roller 3 between the limit brackets A204, and after releasing the limit bracket A204, the damping telescopic rod A205 and the outer spring pop out the limit bracket A204 and slide into the relative limit The staff then pushes the support frame B1091 to slide on the top of the slide slot A109 through the slider, so that the mounting bracket B202 is close to the other end of the winding roller 3, and the other end of the winding roller 3 is limitedly installed on the side of the mounting bracket B202 in the same way. If the staff needs to replace the winding roller 3 of other specifications, the support frame B1091 is pushed to slide in the opposite direction on the inside of the slide slot A109 through the slider, and the limiting bracket A204 is squeezed to slide out of the limiting slot 301 through the damping telescopic rod A205 and the outer spring to release the winding roller 3. The disassembly of the winding roller 3 is completed, and the required winding roller 3 is installed. Then, the staff will After the fabric corner passes through the top of the guide frame 107 and the non-woven fabric scraps are between the two pairs of conveying rollers 108, the staff pushes the limit bracket B308 to rotate through the bearing, rotates from the inside of the limit bracket 304 to release the adjusting pressure plate 305, pushes the adjusting pressure plate 305 upward, and places one end of the non-woven fabric scraps under the pressure plate 307, and then pushes the adjusting pressure plate 305 downward to slide laterally inside the slide groove C303 through the slider, so that the pressure plate 307 squeezes and contacts the upper surface of the non-woven fabric scraps, and fits and contacts with the lower surface of the wavy inner wall of the groove 302, while limiting and clamping the non-woven fabric scraps, squeezes the damping telescopic rod B306 and the outer spring to contract, driving the limit bracket B3 08 slides into the limit slot 304, and after the limit bracket B308 is rotated to completely fit the limit slot 304, the contracted damping telescopic rod B306 and the outer spring generate a reverse thrust on the pressure plate 307, and the non-woven fabric scraps are stably pressed and fixed. Finally, the staff turns on the servo motor 2 and the screw slide 106, so that the servo motor 2 drives the winding roller 3 to rotate and wind the non-woven fabric scraps, and drives the non-woven fabric scraps to pass through the guide frame 107 and limit the guide between the conveying rollers 108. At the same time, the screw slide 106 drives the guide frame 107 to slide repeatedly left and right on the inside of the slide rail 105 through the slider, so that the non-woven fabric scraps are evenly wound up and processed on the outside of the winding roller 3.
