After the cloth is fed, it is guided by the guide roller 2, and then enters between the tension roller 6 and the auxiliary roller 7, and at the same time, pressure is applied to the sides of the tension roller 6 and the auxiliary roller 7. During this period, the pressure at the tension roller 6 is transmitted to the pressure sensor 9 through the connecting plate 5, and the tension of the cloth at the tension roller 6 is constantly detected by the pressure sensor 9; the tension of the cloth at the tension roller 6 is judged by comparing with a reasonable value set in advance.

[0020] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0021] Working principle: When in use, the cloth is fed through an external feeding mechanism, and the control center 10 performs servo control on the feeding speed of the external feeding mechanism. After the cloth is fed, it is guided by the guide roller 2, and then enters between the tension roller 6 and the auxiliary roller 7. At the same time, pressure is applied to the sides of the tension roller 6 and the auxiliary roller 7. During this period, the pressure at the tension roller 6 is transmitted to the pressure sensor 9 through the connecting plate 5, and the tension of the cloth at the tension roller 6 is detected at all times through the pressure sensor 9.

[0022] The pressure sensor 9 sends the pressure signal to the control center 10. The control center 10 determines the tension of the cloth at the tension roller 6 by comparing it with a reasonable value set in advance. When the tension is small, the control center 10 controls the external feeding mechanism to slow down the feeding speed and stop when the tension increases to the set value. When the tension is large, the control center 10 controls the external feeding mechanism to speed up the feeding speed and stop when the tension decreases to the set value, thereby achieving constant control of the cloth tension and preventing deviation.
