[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. Example 1

[0021] like Figure 1 As shown, a cloth guide roller for dyeing and finishing process includes a roller body 1, and annular gaskets 2 are symmetrically sleeved on both ends of the roller body 1. The gaskets 2 are elastic, and the outer diameter A of the gaskets 2 is larger than the outer diameter B of the roller body 1. Example 2

[0022] like Figure 2 and Figure 3 As shown, a straight roller washing machine comprises a washing tank 10, in which a plurality of upper cloth guide rollers 20 and a plurality of lower cloth guide rollers 30 are installed, wherein the upper cloth guide roller 20 comprises an upper cloth guide roller body 201, and an annular upper cloth guide roller gasket 202 is symmetrically sleeved on both ends of the roller body 201, and the difference between the outer diameter of the upper cloth guide roller gasket 202 and the outer diameter of the upper cloth guide roller body 201 is twice the thickness of the fabric; the upper cloth guide roller 20 The lower cloth guide rollers 30 are arranged alternately up and down in the washing tank 10, each of the upper cloth guide rollers 20 is placed in parallel on the two lower cloth guide rollers 30 adjacent to the lower part of the upper cloth guide roller 20, the gasket 202 is in contact with the lower cloth guide roller 30, and a cloth passing gap 40 is formed between the upper cloth guide roller 20 and the lower cloth guide roller 30 below the upper cloth guide roller 20; each lower cloth guide roller 30 is an active roller, and each upper cloth guide roller 20 is a passive roller.

[0023] In the straight roller washing machine implemented in Example 2, the fabric is sequentially passed through each of the upper cloth guide rollers, each of the lower cloth guide rollers and the cloth passing gap. The fabric attached to the surface of the lower cloth guide roller runs faster than the fabric attached to the upper cloth guide roller. The tension of the fabric tends to decrease as it moves, which is suitable for processes that require fabric shrinkage. Example 3

[0024] like Figure 4 and Figure 5 As shown, a straight roller washing machine is different from Example 2 in that the lower cloth guide roller 30 is the cloth guide roller for the dyeing and finishing process described in the first purpose of the utility model, and the upper and lower cloth guide rollers 30 include a lower cloth guide roller body 301, and both ends of the lower cloth guide roller body 301 are symmetrically sleeved with annular lower cloth guide roller gaskets 302, and the difference between the outer diameter of the lower cloth guide roller gasket 302 and the outer diameter of the lower cloth guide roller body 301 is twice the thickness of the fabric; the lower cloth guide roller gasket 302 is in contact with the upper cloth guide roller 20 above the gasket 302, and a cloth passing gap 40 is formed between the upper cloth guide roller 20 and the lower cloth guide roller 30 below the upper cloth guide roller 20.

[0025] In the straight roller washing machine implemented in Example 3, the fabric is sequentially passed through each of the upper cloth guide rollers, each of the lower cloth guide rollers and the cloth passing gap. The fabric attached to the surface of the upper cloth guide roller runs faster than the fabric attached to the lower cloth guide roller. The tension of the fabric tends to increase as it moves, which is suitable for processes that require the fabric to be stretched. Example 4

[0026] like Figure 6 and Figure 7 As shown, a straight roller washing machine is different from Example 2 and Example 3 in that the upper cloth guide roller 20 and the lower cloth guide roller 30 are both cloth guide rollers for the dyeing and finishing process as described in the first purpose of the utility model, the upper cloth guide roller gasket 202 is in contact with the lower cloth guide roller gasket 302 below the upper cloth guide roller 20, and a cloth passing gap 40 is formed between the upper cloth guide roller 20 and the lower cloth guide roller 30 below the upper cloth guide roller 20.

[0027] In the straight roller washing machine implemented in Example 4, the fabric is sequentially passed through each of the upper fabric guide rollers, each of the lower fabric guide rollers and the fabric passing gap, and will not be pressed against the gasket, and will not form an indentation on the sensitive fabric surface.

[0028] The gasket described in the utility model can be made of rubber or synthetic rubber material; the difference between the outer diameter of the gasket and the outer diameter of the roller body is set according to production needs, usually about twice the thickness of the fabric, the larger the difference, the larger the spacing between the upper and lower cloth guide rollers during use, but compared with the spacing of the traditional ordinary tight-type flat washing machine, the spacing has been greatly reduced; the difference is less than twice the thickness of the fabric, the smaller the running tension of the fabric, but it may form an indentation on sensitive fabrics; the gasket described in the utility model is sleeved on the roller body when in use, and when not in use, if the cloth guide roller has a roller shaft, it can be sleeved on the roller shaft, if the cloth guide roller does not have a roller shaft, it can be placed inside the roller body to achieve storage of the gasket.

[0029] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
