The part of the right vertical guide column 207 located between the second limit plate 113 and the right bearing seat 205 is sleeved with a right compression spring 208.

[0055] Through the coordinated design of the first left strip guide hole 104, the second left strip guide hole 107, the left bearing seat 201, the left bearing 202, the left vertical guide column 203 and the left compression spring 204, as well as the first right strip guide hole 112, the second right strip guide hole 115, the right bearing seat 205, the right bearing 206, the right vertical guide column 207 and the right compression spring 208, on the one hand, it ensures that the left flattening roller 103 and the right flattening roller 111 can move upward to provide sufficient space for replacing different small flattening rollers 102 and large flattening rollers 110; on the other hand, it ensures that the small flattening roller 102 and the left flattening roller 103, as well as the large flattening roller 110 and the right flattening roller 111 are in a rolling and fitting state.

[0056] like Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, the driving structure 300 includes a driving motor 301, and the driving motor 301 is arranged on the upper surface of the non-woven fabric sizing platform 100, and a driving wheel 302 is provided on the output shaft of the driving motor 301;

[0057] The end of the left second rotating shaft 211 on the same side as the driving motor 301 extends out of the left support frame 101 and is sleeved with a left driving wheel 303. The driving wheel 302 is connected to the left driving wheel 303 via a left driving wheel belt 304.

[0058] The end of the left second rotating shaft 211 on the same side as the driving motor 301 extends out of the right supporting frame 109 and is sleeved with a right driving wheel 305 . The driving wheel 302 is connected to the right driving wheel 305 via a right driving wheel belt 306 .

[0059] The design of the driving structure 300 ensures synchronous operation of the small smoothing roller 102 and the large smoothing roller 110 .

[0060] Working principle:

[0061] A left support frame 101 is provided on the left side of the non-woven fabric arranging platform 100 , a right support frame 109 is provided on the right side of the non-woven fabric arranging platform 100 , and a winding frame can be provided on the right side of the right support frame 109 for winding the non-woven fabric.

[0062] The non-woven fabric passes between the small flattening roller 102 and the left flattening roller 103, and between the large flattening roller 110 and the right flattening roller 111. The small flattening roller 102 and the right flattening roller 111 flatten the non-woven fabric downwards, and the power of the drive motor 301 of the drive structure 300 is turned on. The drive motor 301 can drive the active wheel 302 to rotate, and drive the left drive wheel 303 and the right drive wheel 305 at the same speed respectively, to ensure that the rotation speed of the small flattening roller 102 and the large flattening roller 110 is consistent. There is a difference in the radius of the small flattening roller 102 and the large flattening roller 110, which results in the small flattening roller 102 and the large flattening roller 110 driving the non-woven fabric to move at an inconsistent speed, thereby producing a pulling effect on the non-woven fabric. While pulling, the left flattening roller 103 and the right flattening roller 111 respectively flatten the non-woven fabric downwards, so that the pulling and flattening functions on the non-woven fabric exist at the same time, thereby enhancing the pulling and flattening effect.

[0063] Because the actual sizes of non-woven fabrics are different and the parts that need to be pulled and flattened vary in size, the first automatic telescopic cylinder 122 and the second automatic telescopic cylinder 127 can be adjusted to change the distance between the left support frame 101 and the right support frame 109. This can adjust the situation where the actual size of the non-woven fabric and the part that needs to be pulled and flattened is very small and it is impossible to span between the left support frame 101 and the right support frame 109 to pull and flatten it.

[0064] Because the actual degree of wrinkles of non-woven fabrics is different, the required pulling and flattening strength is also different. Through the design of the small flattening roller replacement port 108 and the large flattening roller replacement port 116, different small flattening roller replacement ports 108 and large flattening roller replacement ports 116 can be replaced. When the pulling and flattening strength requirement is high, a small flattening roller 102 with a smaller diameter is selected according to the actual situation, and a large flattening roller 110 with a larger diameter is selected to cooperate. When the pulling and flattening strength requirement is low, a small flattening roller 102 with a slightly larger diameter is selected according to the actual situation, and a large flattening roller 110 with a slightly smaller diameter is selected to cooperate (at this time, it is required to ensure that the diameter value of the small flattening roller 102 is still smaller than the diameter value of the large flattening roller 110).

[0065] In addition, through the coordinated design of the first left strip guide hole 104, the second left strip guide hole 107, the first right strip guide hole 112, the second right strip guide hole 115 and the adjustment assembly 200 (mainly the left bearing seat 201, the left bearing 202, the left vertical guide column 203, the left compression spring 204, the right bearing seat 205, the right bearing 206, the right vertical guide column 207 and the right compression spring 208), on the one hand, it ensures that the left flattening roller 103 and the right flattening roller 111 can move upward to provide sufficient space for replacing different small flattening rollers 102 and large flattening rollers 110; on the other hand, it ensures that the small flattening roller 102 and the left flattening roller 103, and the large flattening roller 110 and the right flattening roller 111 are in a rolling and fitting state.

[0066] During operation, the driving motor 301 is started to drive the driving wheel 302 to rotate, and at the same time, the left driving wheel 303 and the right driving wheel 305 are driven to rotate synchronously (at the same speed) through the left driving wheel belt 304 and the right driving wheel belt 306 respectively.

[0067] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application.
