[0026] 1. This utility model utilizes a rotary motor, a winding frame, a worm gear, a worm wheel, a screw, and a clamping plate. The operator passes the fabric through the winding frame, then rotates the worm gear via a handwheel. The worm gear meshes with the worm wheel, driving the screw to rotate. The rotating screw converts the rotational motion into linear motion of the clamping plate, causing it to displace and press one end of the fabric down. The rotary motor then drives the winding frame to rotate, winding longer pieces of fabric into a cylindrical shape. This reduces the need for a large main body of the device due to longer fabric, thus reducing the space occupied by the device. After cutting, the operator reverses the handwheel to reverse the worm gear, worm wheel, and screw, freeing the clamping plate from pressing down on one end of the fabric. The cut fabric can then be directly pulled out from outside the winding frame for unloading. This reduces space requirements and eliminates the need for multiple folds of longer fabric, saving time and effort.

The present invention features a sliding sleeve with a very smooth surface, which reduces the friction between the fabric and the winding frame, making it easier for workers to pull out the fabric and complete the unloading process; and avoids the phenomenon that the fabric is difficult to remove due to a large contact area between it and the winding frame.

[0028] 3. This utility model, through the setting of a first grounding wire, a through-hole conductive slip ring, and a second grounding wire, uses a stainless steel support for the sliding sleeve, which has a smooth surface and low resistance. Therefore, the first grounding wire, the through-hole conductive slip ring, and the second grounding wire discharge the static electricity accumulated on the surface of the sliding sleeve into the ground, avoiding the phenomenon that the fabric is difficult to pull out for feeding due to static electricity adhering to the surface of the sliding sleeve; reducing the resistance of static electricity to feeding.
