It should be noted that, in the embodiment of the present application, the first roller 420 and the second roller 430 may not be provided, and the first roller 420 and the second roller 430 are provided to facilitate conveying the fabric.

The two coating rollers 221 include one driving roller 221a and one driven roller 221b therein, and the coating mechanism 200 includes a driving member configured to drive each driving roller 221a to rotate, the driving roller 221a being capable of rotating the driven roller 221b in the opposite direction to the driving roller 221a by the driving member or the driving roller 221a being capable of rotating the driven roller 221b in the opposite direction to the driving roller 221a by the fabric. The drive roller 221a is rotatably supported by the first support portion 211, and the driven roller 221b is rotatably supported by the second support portion 212.

In another possible embodiment, when the fabric is rolled by the rolling mechanism 600, the fabric is conveyed forward, the fabric passes through between the driving roller 221a and the driven roller 221b, friction is generated between the fabric and both the driving roller 221a and the driven roller 221b, and the fabric can drive the driven roller 221b and the driving roller 221a to rotate in opposite directions.

When the piston rod moves axially, the second supporting part 212 in transmission connection with the piston rod moves close to or away from the first supporting part 211, so that the distance between the driving roller 221a and the driven roller 221b is adjusted, fabrics with different thicknesses can be coated, and the coating thickness can be adjusted.

As an alternative embodiment, the second adjusting assembly 230 may also be driven by air pressure, that is, the hydraulic cylinder is replaced by a pneumatic cylinder, and the piston rod is driven to move axially by injecting air into the pneumatic cylinder, which is similar to the principle of the hydraulic cylinder and will not be described herein again.

The pressure sensor 222 transmits the detected pressure signal to the controller 223, and the controller 223 receives the pressure signal and determines whether the pressure is appropriate, and then controls the control assembly of the second adjustment assembly 230 to inject hydraulic fluid into the hydraulic cylinder or gas into the hydraulic cylinder. It is thereby possible to achieve the approaching or separating of the second support portion 212 with respect to the first support portion 211, thereby adjusting the interval between the drive roller 221a and the driven roller 221b to adjust the pressing force between the drive roller 221a and the driven roller 221 b.
