In the invention, when the fabric is transferred on the tensioning roller assembly, if the tensioning force of the fabric is too large, the fabric can extrude the guide plate to compress the first spring, thereby playing a role in relieving the tensioning force; if the tension force is continuously increased, the fabric slides to the lower end of the guide plate due to the inclined arrangement of the guide plate, so that the fabric extrudes the movable plate to drive the movable plate to move towards the annular positioning plate, and the second spring is in a compressed state; when the tension of the fabric is reduced, the pressure of the fabric on the moving plate is reduced, the second spring extends, and the moving plate drives the fabric to move in the direction towards the annular baffle plate so as to improve the tension; if the tension is still small and the pressure of the fabric on the first spring is not enough, the first spring extends upwards to drive the fabric to move upwards, so that the tension of the guide plate on the fabric is increased; in the above, the first spring and the second spring are in dynamic balance, and both may be compressed or extended simultaneously to reach a balanced state; when the tension of the fabric is too large, the fabric and the tension tend to be in a compressed state so as to reduce the tension in fabric transmission; when the tension of the fabric is too small, the fabric and the tension tend to extend out, so that the tension in fabric transmission is increased. To sum up, tensioning roller subassembly can be from adjusting the tensile force in the fabric transmission slowly, avoids because the too big surface fabric that leads to of tensile force damages, also can avoid simultaneously because the poor problem of surface fabric rolling effect that the tensile force undersize leads to.

In the invention, the cross-shaped bulge at the end part of the winding roller 3 is inserted into the cross-shaped groove of the fastener 13 in a matching manner, so that the winding roller is quickly mounted and dismounted, and the replacement efficiency of the winding roller is improved. Baffle 14, fastener 13 and through-hole 11 all are located same vertical plane towards the terminal surface of clamping component 6, are convenient for fix a position the side of surface fabric, improve the rolling quality.

In an alternative embodiment, the tension roller assembly 8 includes a tension roller rotating shaft 81, an annular baffle 82, a guide plate 84, a first spring 85, a moving plate 87, a second spring 88 and an annular positioning plate 83;

the annular baffle 82 and the annular positioning plate 83 are respectively arranged at two ends of the tension roller rotating shaft 81; the tension roller rotating shaft 81 is connected with a power device;

a plurality of guide plates 84 are annularly and uniformly distributed by taking the axis of the tension roller rotating shaft 81 as a reference, and strip-shaped spaces 86 are arranged between the adjacent guide plates 84; each guide plate 84 is connected with a plurality of first springs 85, wherein the bottom of each first spring 85 is connected with the tension roller rotating shaft 81, and the top of each first spring 85 is connected with the bottom of each guide plate 84; the guide plate 84 is obliquely arranged, and has a higher end facing the annular baffle 82 and a lower end facing the annular positioning plate 83;

the end surface of the moving plate 87 facing the annular positioning plate 83 is connected with one end of a second spring 88, and the other end of the second spring 88 is arranged on the annular positioning plate 83; the moving plate 87 slides in the bar-shaped space 86.

The end face of the annular baffle 82 is in non-pressure contact with the end faces of the plurality of guide plates 84.

In the invention, when the fabric is transferred on the tensioning roller assembly 8, if the tensioning force of the fabric is too large, the fabric extrudes the guide plate 84 to compress the first spring 85, thereby playing a role in relieving the tensioning force; if the tension force is continuously increased, the fabric slides towards the lower end of the guide plate 84 due to the inclined arrangement of the guide plate 84, so that the fabric extrudes the moving plate 87 to drive the moving plate 87 to move towards the annular positioning plate 83, and at the moment, the second spring 88 is in a compressed state;

when the tension of the fabric is reduced, the pressure of the fabric on the moving plate 87 is reduced, the second spring 88 extends, and the moving plate 87 drives the fabric to move in the direction towards the annular baffle 82 so as to improve the tension; if the tension is still small and the pressure of the fabric on the first spring 85 is not enough, the first spring 85 extends upwards to drive the fabric to move upwards, so that the tension of the guide plate 84 on the fabric is increased;

in the above, the first spring 85 and the second spring 88 are in dynamic balance, and both may be compressed or extended simultaneously to reach a balanced state; when the tension of the fabric is too large, the fabric and the tension tend to be in a compressed state so as to reduce the tension in fabric transmission; when the tension of the fabric is too small, the fabric and the tension tend to extend out, so that the tension in fabric transmission is increased.

In conclusion, the tensioning roller assembly 8 can automatically adjust the tensioning force in the fabric transmission process, so that the fabric damage caused by too large tensioning force can be avoided, and the problem of poor fabric winding effect caused by too small tensioning force can be avoided.

In an alternative embodiment, the plurality of first springs 85 corresponding to each of the guide plates 84 are equally spaced to ensure the stress balance of the guide plates 84 and to ensure the best support effect of the first springs 85 on the guide plates 84.
