[0001] The invention belongs to the technical field of dyeing and finishing processes, and in particular relates to a cloth guiding device and a gas-liquid cloth dyeing machine comprising the cloth guiding device. Background Art

[0002] The gas-liquid dyeing machine mainly uses a circulating airflow to pull the fabric to make a periodic circulation motion. The circulating dye liquid is exchanged with the dyed fabric through a combination of dye liquid flow nozzles. The dyeing process of the dye on the fabric is completed through a certain periodic cycle exchange. In the prior art, the cloth lifting roller is one of the main power sources for the gas-liquid dyeing machine to pull the fabric into circulation. The pulling force of the cloth lifting roller on the fabric is too large, which is easy to cause the following problems: 1. It is easy to reach the elastic limit of the fabric, making the fabric unable to recover; 2. The fabric is shrinking under the strong pulling force, causing wrinkles in the fabric. Not only that, the relative sliding of the fabric on the roller surface of the cloth lifting roller will cause scratches on the fabric. In addition, since the cloth lifting roller is a rotating mechanical structure, it affects the sealing of the gas-liquid dyeing machine, and when the running speeds of the fabric and the cloth lifting roller are inconsistent, the cloth blockage is difficult to clear. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a cloth guiding device, the purpose of which is to solve the technical problem that in the prior art, the cloth lifting roller is one of the main power sources for the air-liquid dyeing machine to pull the fabric into circulation, the cloth lifting roller has too much pulling force on the fabric, which easily causes the fabric to be damaged such as wrinkles, and the relative sliding of the fabric on the roller surface of the cloth lifting roller will cause scratches on the fabric; in addition, since the cloth lifting roller is a rotating mechanical structure, it affects the sealing of the air-liquid dyeing machine, and when the running speeds of the fabric and the cloth lifting roller are inconsistent, the cloth blockage is difficult to clear.

[0012] Figure 2 It is a schematic diagram of the structure of the gas-liquid dyeing machine in Example 2. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following is a detailed description of the present invention in conjunction with the accompanying drawings. Figure 1-2 , the present invention is further described in detail.

[0014] Example 1

[0015] The fabric guiding device provided in this embodiment has the following specific solutions:

[0016] like Figure 1As shown, the fabric guiding device 1 comprises a first liquid flow nozzle 11, a first curved pipe 12, a second liquid flow nozzle 13, a second curved pipe 14, a third liquid flow nozzle 15 and a wind nozzle 16. The first liquid flow nozzle 11, the first curved pipe 12, the second liquid flow nozzle 13, the second curved pipe 14, the third liquid flow nozzle 15 and the wind nozzle 16 are connected in sequence and are distributed in an S shape. The fabric passes through the first liquid flow nozzle 11, the first curved pipe 12, the second liquid flow nozzle 13, the second curved pipe 14, the third liquid flow nozzle 15 and the wind nozzle 16 in sequence and then enters the next mechanism. The fabric does not need a fabric lifting roller. Multiple potential forces are provided by multiple nozzles to achieve low tension fabric guiding, thereby avoiding damage to the fabric when the fabric lifting roller is used as the main power source. Among them, the spray direction of the first liquid flow nozzle 11 is aimed at the first elbow 12, the spray direction of the second liquid flow nozzle 13 is aimed at the second elbow 14, and the spray direction of the third liquid flow nozzle 15 is aimed at the wind nozzle 16, and the angle between the inclination angle of the first liquid flow nozzle 11 and the vertical line is -8 to 16 degrees. When the first liquid flow nozzle 11 is in the fabric operation, the first liquid flow nozzle 11, the second liquid flow nozzle 13, the third liquid flow nozzle 15 and the wind nozzle 16 provide power to ensure the feasibility of low-tension cloth transportation. In particular, the third liquid flow nozzle 15 and the wind nozzle 16 are jointly sleeved with a nozzle shell, so that the atomization effect is optimized. The first elbow 12 and the second elbow 14 not only take into account the required length of the working stroke, but also reduce the overall height of the cloth guiding mechanism, saving installation space, and at the same time, the second elbow 14 realizes the impregnation of the fabric and improves the dyeing efficiency.

[0017] The specific structures of the first liquid flow nozzle 11, the second liquid flow nozzle 13, and the third liquid flow nozzle 15 in this embodiment are all prior art and have been disclosed in the patent - an anti-rotation nozzle for a dyeing machine (CN207347767U), which will not be repeated here.

[0018] Example 2

[0019] like Figure 2 As shown, this embodiment provides an air-liquid cloth dyeing machine, comprising a cylinder 2, a cloth storage tank 3 built in the cylinder 2, and a cloth guiding device 1 in Embodiment 1, wherein the cloth guiding device 1 is built in the cylinder 2 and fixedly arranged above the cloth storage tank 3. In this embodiment, the cloth outlet of the cloth storage tank 3 is aligned with the first liquid flow nozzle 11, and the air nozzle 16 is movably connected with the swing cloth bucket 4, and the cloth outlet of the swing cloth bucket 4 is aligned with the cloth drop opening of the cloth storage tank 3.

[0020] In this embodiment, during a single cycle of the fabric, the first liquid flow nozzle 11, the second liquid flow nozzle 13, the third liquid flow nozzle 15 and the wind nozzle 16 provide multiple forces to guide the fabric. The dye liquid sprayed by the first liquid flow nozzle 11 and the second liquid flow nozzle 13 penetrates and dyes the fabric. In addition, the fabric is dyed in the second curved pipe 14, and then the fabric is exchanged with the atomized dye liquid through the combination of the third liquid flow nozzle 15 and the wind nozzle 16, and finally passes through the swing bucket 4 and falls into the fabric storage tank 3 in an orderly manner, thereby completing a cycle. According to the dyeing process requirements, the required number of cycles is completed to achieve uniform dyeing of the fabric.

[0021] In this embodiment, the device for swinging the cloth bucket 4 to achieve swinging has been disclosed in the patent - Cloth drop point adjustment device for gas-liquid dyeing machine (CN211227681U), which will not be repeated here.

[0022] This embodiment also provides an application of the air-liquid dyeing machine, based on the above-mentioned air-liquid dyeing machine, including pre-treatment and overflow dyeing treatment of the fabric, when the fabric needs to be pre-treated, open the first liquid flow nozzle 11, the third liquid flow nozzle 15 and the air nozzle 16. The pre-treatment is used to expand the fabric fibers, and wash and scour the fabric.

[0023] When overflow dyeing is required for the fabric, the first liquid flow nozzle 11, the second liquid flow nozzle 13 and the third liquid flow nozzle 15 are opened. Overflow dyeing is performed by spraying the first liquid flow nozzle, the second liquid flow nozzle and the third liquid flow nozzle, and the running speed of the fabric is controlled to control the soaking time of the fabric in the fabric guide mechanism, and also the dyeing effect thereof.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
