Referring again to fig. 1, the cloth guide mechanism 200 further includes a bending roll 209, and the bending roll 209 is further away from the first cloth guide roll 203 than the first opening roll 202 along the cloth guide direction. During fabric guiding, the fabric 800 passes through the bending roll 209 and then passes through the first expander roll 202.

It is understood that the cloth guide mechanism 200 further includes a plurality of transfer rollers 210, and the plurality of transfer rollers 210 are rotatably coupled to the frame 201 for transferring the cloth 800.

In a specific example, in the liquid ammonia processing apparatus shown in fig. 1, there are 4 tension frames 900, and the tensions of the 4 tension frames are sequentially controlled to be 180N to 250N, 35N to 45N, and 160N to 200N in the cloth guiding direction. Alternatively, the tensions of the 4 tension brackets are sequentially controlled to 200N, 40N, and 180N.

In yet another embodiment of the present invention, a method of guiding a cloth is provided. The cloth guiding method adopts the cloth guiding mechanism 200, and comprises the following steps:

sequentially enabling the cloth 800 to pass through a first opening roller 202, a first cloth guide roller 203, a second cloth guide roller 204 and a second opening roller 205; the cloth 800 is driven to move by the first cloth guide roller 203 and the second cloth guide roller 204, and simultaneously the first scutching roller 203 and the first cloth guide roller 203 are driven to synchronously rotate, and the second scutching roller 205 and the second cloth guide roller 204 are driven to synchronously rotate.

Further, while the cloth 800 is sequentially passed through the first opening roll 202, the first cloth guide roller 203, the second cloth guide roller 204, and the second opening roll 205, different surfaces of the cloth 800 are controlled to be in contact with the first opening roll 202 and the second opening roll 205, respectively. When the cloth guide mechanism 200 is used for guiding cloth, different surfaces of the cloth 800 are controlled to be in contact with the first open width roller 202 and the second open width roller 205 respectively, so that the different surfaces of the cloth 800 can be opened, and the flatness of the different surfaces of the cloth 800 is improved.

In a specific example, when the cloth 800 passes through the first opening roll 202, the first cloth guide roll 203, the second cloth guide roll 204 and the second opening roll 205 in sequence, the cloth 800 is controlled to be positioned on the same side of the first cloth guide roll 203 at the cloth outlet end of the first opening roll 202 and the cloth inlet end of the first cloth guide roll 203. This makes it possible to obtain a rotation direction of the first opening roll 202 opposite to the cloth guide direction, to make the contact between the first opening roll 202 and the cloth 800 more sufficient, and to further improve the flatness of the surface of the cloth 800 in contact with the first opening roll 202.

In another specific example, when the cloth 800 is sequentially passed through the first opening roll 202, the first cloth guide roller 203, the second cloth guide roller 204, and the second opening roll 205, the cloth 800 is controlled to be positioned on a different side of the second opening roll 205 at the cloth outlet end of the second cloth guide roller 204 and the cloth inlet end of the second opening roll 205. This allows the second expander roll 205 to rotate in the direction opposite to the cloth guide direction, and allows the second expander roll 205 to contact the cloth 800 more sufficiently, thereby further improving the flatness of the surface of the cloth 800 contacting the second expander roll 205.

Referring again to fig. 1-8, yet another embodiment of the present invention provides a liquid ammonia processing apparatus 100. The liquid ammonia processing device 100 includes a liquid ammonia reaction chamber 300 and a cloth guide mechanism 200, and the cloth guide mechanism 200 is located in the liquid ammonia reaction chamber 300. When the cloth 800 is treated with liquid ammonia, the cloth 800 becomes soft, and wrinkles are more likely to occur on the surface of the cloth 800. When the liquid ammonia processing equipment 100 is adopted to carry out liquid ammonia treatment on the cloth 800, the problem that the cloth 800 becomes soft and wrinkles caused can be effectively solved, and the flatness of the cloth 800 is improved.
