The two second limiting grooves 22 are respectively connected end to end with the first limiting groove 21 and the third limiting groove 23. The two sliding posts 31 on the vertical plate 20 are respectively slidably installed inside the two folding grooves;

[0040] Furthermore, the indicator light 15 can work when the cloth is pressed and wrinkles are removed adaptively, so as to remind the staff that there is a problem with the cloth rolling when wrinkles appear, so that the staff can check the effect of automatic wrinkle removal in time.

[0041] Please see attached Figure 1 -Attached Figure 3 In a preferred embodiment, the winding limiting assembly includes: a first side plate 2, two first side plates 2, both of which are mounted on the top of the bottom plate 1, a winding roller 3 is rotatably mounted between the two first side plates 2, a first motor 4 is mounted on the corresponding side of the corresponding first side plate 2, and the output shaft of the first motor 4 is mounted at the center of the end surface of the winding roller 3, and two second side plates 17 are also vertically symmetrically fixedly mounted on the top of the bottom plate 1, and two limiting rollers 16 are horizontally rotatably mounted between the two second side plates 17;

[0042] Specifically, the winding paper drum for winding the cloth is fixedly sleeved on the winding roller 3, and then the end of the cloth is installed on the winding paper drum, and the cloth is passed through two limiting rollers 16 in sequence to limit the cloth to be wound.

[0043] Please see attached Figure 1 -Attached Figure 3 In a preferred embodiment, the driving assembly includes: a round roller 11, two round rollers 11, the two round rollers 11 are respectively arranged at the two ends of the conveyor belt 5, the two round rollers 11 are vertically fixedly installed at the bottom center of each round roller 11, the two ends of each rotating rod 6 are rotatably installed on the top of the bottom plate 1, the bottom of the bottom plate 1 is installed with a second motor 7, and the output shaft of the second motor 7 is installed at the bottom center of the corresponding rotating rod 6;

[0044] Furthermore, the first motor 4 is used to drive the winding roller 3 to rotate and wind up the cloth, and the second motor 7 is used to drive the conveyor belt 5 to rotate to prevent and remove wrinkles on the wound cloth.

[0045] The working principle of the present invention is as follows: first, the winding paper drum for winding the fabric is fixedly sleeved on the winding roller 3, and then the end of the fabric is installed on the winding paper drum, and the fabric passes through two limiting rollers 16 in sequence to limit the fabric to be wound, and then the first motor 4 is started to drive the winding roller 3 and the winding paper drum to rotate, so as to realize the winding of the fabric;

[0046] When the second motor 7 is started synchronously during winding, the second motor 7 drives the corresponding rotating rod 6 to rotate, the rotating rod 6 drives the round roller 11 to rotate, the round roller 11 drives the conveyor belt 5 to rotate, the conveyor belt 5 drives the telescopic rod 25 to rotate, the telescopic rod 25 drives the vertical plate 20 to rotate, the vertical plate 20 drives the slider 27, the second spring rod 29, the pressing plate 14, the first copper plate 18 and the second copper plate 19 to rotate, when the two pressing plates 14 on the conveyor belt 5 rotate to the two sides of the cloth, due to the arrangement of the strip plate 13 and the slope 24 thereon, the contact between the pressing plate 14 and the slope 24 will cause the two pressing plates 14 to move closer to each other and clamp the cloth and cause the first spring rod 28 to generate tension. It should be noted that the second motor 7 is a variable speed motor, so that the speed of the conveyor belt 5 rotation is consistent with the speed of cloth winding, so that the corresponding two pressing plates 14 clamp the cloth and move with the cloth, ensuring that the two sides of the cloth will not be wound during winding, thereby affecting the winding effect;

[0047] After the corresponding two pressing plates 14 clamp the fabric, due to the arrangement of the second limiting groove 22 and the third limiting groove 23, when the vertical plate 20 passes through the second limiting groove 22 and moves to the third limiting groove 23, the sliding column 31 will move toward the direction close to the conveyor belt 5, and the movement of the sliding column 31 drives the vertical plate 20, the sliding block 27 and the fixed end of the second spring rod 29 to move toward the direction close to the conveyor belt 5 and causes the second spring rod 29 to generate tension;

[0048] If the cloth is wrinkled at this time, the tension generated by the second spring rod 29 will cause the corresponding two pressing plates 14 to drive the clamped cloth to move together, so as to eliminate the wrinkles of the cloth. It should be noted that when the pressing plate 14 moves, it will drive the second copper plate 19 to move, and further the second copper plate 19 will contact the first copper plate 18 and make the indicator light 15 work, so as to remind the staff that the cloth winding needs to be checked in time;

[0049] If the cloth has no wrinkles, the second spring rod 29 is arranged so that the corresponding two pressing plates 14 for clamping the cloth will not move, and the cloth will not be forcibly pulled to deform, thereby further realizing adaptive wrinkle removal of the cloth.

[0050] When the pressing plate 14 and the strip plate 13 are not in contact, the pulling force generated by the first spring rod 28 will make the two pressing plates 14 move away from each other, and the cloth will no longer be clamped, which facilitates the cloth winding effect of the winding paper roller. In summary, the cloth can be wound continuously and stably by reciprocating in sequence, thereby improving the cloth winding effect of the device.

[0051] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
