[0031] The controller can be used to start motor 27 to drive threaded rod 28 to rotate, so that the movable plate 4 moves along the guide rod 3, and the overall position of the cloth clamping device is adjusted. After moving to the specified position, the user passes the cloth to be rolled up between clamping roller 2 17 and clamping roller 15, and fixes it on the cloth stretching machine. At this time, the user can start motor 16 through the controller to drive threaded rod 10 to rotate, and drive the movable plate 11 to move along the track of the limit rod 9, so that the upper and lower positions of the two clamping rollers can be adjusted to the specified positions. At this time, the user starts the cloth stretching machine for winding. During the process, the user can also adjust the positions of the cloth clamping device and the clamping rollers to meet different winding requirements.

[0032] Embodiment 2: A synchronous cleaning assembly is provided at the bottom of the support plate 5, and the synchronous cleaning assembly includes a movable plate 11, the movable plate 11 is threadedly connected to the threaded rod 10, and the threaded rod 10 penetrates the movable plate 11 and extends into the bottom of the movable plate 11, both sides of the bottom of the movable plate 11 are fixedly connected with spring dampers 12, the bottom of the spring damper 12 is fixedly connected with a fixed block 13, a fixed shaft 16 is fixedly connected between two adjacent fixed blocks 13, and a clamping roller 2 17 is slidably connected to the outer wall of the fixed shaft 16, a rotating shaft 14 is rotatably connected between two adjacent fixed blocks 13, and the rotating shaft 14 penetrates the fixed block 13 and extends to the outside of the fixed block 13, The outer wall of the fixed block 13 is fixedly connected to a clamping roller 15, and both ends of the rotating shaft 14 are fixedly connected to protrusions 19.

The user starts the motor 27 through the controller to drive the threaded rod 28 to rotate, so that the movable plate 4 moves along the guide rod 3, and the overall position of the cloth clamping device is adjusted. After moving to the specified position, the user passes the cloth to be rolled up between the clamping roller 2 17 and the clamping roller 15, and fixes it on the cloth stretching machine. At this time, the user can start the motor 16 through the controller to drive the threaded rod 10 to rotate, and drive the movable plate 11 to move along the track of the limit rod 9, so that the upper and lower positions of the two clamping rollers can be adjusted to the specified positions. At this time, the user starts the cloth stretching machine. During the winding process, the user can also adjust the positions of the cloth clamping device and the clamping roller to adapt to different winding requirements. At the same time, during the winding process, the thickness of the output and input ends will change as the cloth is continuously transmitted, and the overall tension of the cloth will change during the process. At this time, the spring damper 12 will expand or contract to match the change in cloth tension, further avoiding damage to the cloth. At the same time, the rotation of the clamping roller 15 will drive the rotating shaft 14 and the protrusions 19 at both ends of the rotating shaft 14 to rotate. Due to the shape characteristics of the protrusion 19, the protruding part will continuously touch the air cylinder 20 during rotation, and the air cylinder 20 will blow out air through the air pipe 21 to clean the outer skin of the cloth.
