Detailed ways

Below in conjunction with accompanying drawing and embodiment, the utility model is further described:

Embodiment 1: Referring to FIG. 1, a cloth winding device includes a frame 1, a winding shaft 2 arranged on the frame 1, and a driving motor 3. The output shaft of the driving motor is connected to the One end of the reeling shaft is connected, the frame is also provided with a pushing mechanism, and the pushing mechanism is arranged on the right side of the reeling shaft;

The pushing mechanism includes an upper pressing roller 5, a lower pressing roller 6, a rotating shaft 7 and a motor 8. The frame is provided with two sets of vertical slide rails 9, and two sets of vertical slide rails are respectively provided with a slide rail. Slide block 10, both ends of the upper pressure roller and the lower pressure roller are respectively rotatably mounted on two sets of the sliders, and the upper pressure roller is arranged above the left side of the lower pressure roller;

Both ends of the rotating shaft are rotatably mounted on the frame below the vertical slide rails on both sides, and the output shaft of the motor is connected with the middle of the rotating shaft through a belt;

Two ends of the rotating shaft are respectively provided with a cam 11 , each group of the cams is disposed directly below the corresponding sliding block, and the outer edge surface of the cam abuts against the bottom surface corresponding to the sliding block.

In this embodiment, in actual use, the cloth passes between the upper pressing roller and the lower pressing roller, and is then wound onto the winding shaft. During the winding process of the reeling shaft, the motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the cams on both sides to rotate, so that the cam can be used to push the slider up, that is, the upper pressure roller and the lower pressure roller move upward, and the convex part of the cam When it goes down, under its own weight, the upper pressure roller and the lower pressure roller move downward, so that the upper pressure roller and the lower pressure roller can move up and down, so that when moving downward, the fabric is pulled, that is, the fabric at the rewinding shaft will be pulled. Tighten, so that when the reel is rewinding, the cloth roll is more compact, and when moving upward, the fabric can be relaxed, which can ensure the normal rewinding of the reel and prevent the fabric from being stretched during the rewinding process. , In this way, in the process of fabric winding, one loosening and one tightening ensures the winding quality, the same length, the diameter of the fabric roll is smaller, and the subsequent transportation takes up less space and the cost is lower.
