In addition, the traditional dyeing machine uses the force of water flow as the power for the fabric running, the normal movement of the fabric must depend on the water flow, and once the water flow exists, the moisture content of the fabric after dyeing and finishing is higher due to the water absorption of the fabric. In addition, because the traditional dyeing machine uses larger water flow to impact the fabric, the fabric is dyed in a rope-shaped mode, and the fabric is wrapped by the water flow to advance, so that the fabric is easy to crease, and finally, the problem of uneven fabric dyeing is caused.

The air flow or gas-liquid dyeing machine takes the air flow as the power for the fabric to run, and the water flow is only used as the dyeing medium, so the air flow or gas-liquid dyeing machine can enable the fabric to normally move in the dyeing machine only by using the air flow under the action of no water flow, and the air flow can be used for effectively and mechanically finishing the fabric. However, the fabric still contacts with liquid in the dyeing and finishing process, and if the fabric is not treated, the problems of crease generation, uneven dyeing and the like of the fabric still occur.

With reference to fig. 8-10, the cloth swinging hopper includes a cloth swinging pipe 8, a connecting seat 9, a shaft sleeve 91 and a supporting seat 92, wherein the shaft sleeve 91 is disposed on the upper portion of the connecting seat 9, and the supporting seat 92 is disposed on the lower portion of the connecting seat 9; an upper mounting part 81 is arranged at the upper end of the cloth swinging pipe 8, a supporting shaft 82 is arranged below the upper mounting part 81, and the supporting shaft 82 and the upper mounting part 81 are coaxially arranged; the upper mounting part 81 is arranged in the shaft sleeve 91, and the supporting shaft 82 is arranged in the supporting seat 92; the cloth swinging pipe 8 comprises an inlet pipe section 83, a guide pipe section 84 and an outlet pipe section 85, and the inlet pipe section 83, the guide pipe section 84 and the outlet pipe section 85 are connected in sequence; the distance between the two side walls 85a of the outlet pipe section 85 in the horizontal direction gradually increases along the moving direction of the fabric. The inlet pipe section 83 is arranged obliquely downward along the moving direction of the fabric, the outlet pipe section 85 is arranged transversely or obliquely downward, and the guide pipe section 84 gradually changes the moving direction of the fabric from the oblique downward to the transverse or oblique downward. In order to facilitate the connection with other parts of the dyeing machine, a flange 93 is arranged at the top end of the connecting base 9. Preferably, the distance between the top and bottom walls 85b of the outlet pipe section 85 decreases gradually in the direction of movement of the fabric. The shape of the outlet pipe section 85 is gradually changed from a round pipe into a flat shape along the moving direction of the fabric, on one hand, the shape is matched with the fabric with the overall variable cross section, and simultaneously, the direction of the fluid in the pipeline can be changed, so that the fabric is extended in the weft direction, and the fabric is further extended in the outlet pipe section 85.

The support base 92 is composed of a support base housing 921 and a support base shaft core 922, and the support base shaft core 922 is rotatably sleeved in the support base housing 921.

In the dyeing and finishing process, the air current sprayed from the nozzle 86 of the swinging cloth hopper impacts the fabric forward, and because the distance between the pipe walls at two sides of the outlet pipe section 85 in the horizontal direction is gradually increased along the moving direction of the fabric, the fabric can be unfolded towards two sides under the action of the wind power in the swinging cloth pipe 8 and moves in a scattering manner. Because the finishing unit 5 is located the corresponding position that the swinging hopper spout 86 faces, therefore the fabric can strike on the tooth pipe row 51 of finishing unit 5, realize the effect of "patting", tooth pipe 511 surface is smooth, and the fabric can freely change the motion state on tooth pipe 511 to avoid the fabric to receive external force extrusion for a long time and produce the problem of crease, simultaneously because the fabric is in irregular motion state always, can fully exchange with the dye liquor omnidirectionally, consequently can avoid producing the uneven problem of dyeing. In addition, because the tooth pipe is a circular arc surface, the tooth pipe can beat the fabric and also can rub the fabric, and the fabric is softer and more fluffy after beating and rubbing. Moreover, repeated impact and beating of the fabric and the tooth row tubes can effectively release the internal stress of the fabric, so that the fabric generates a pre-shrinking effect.

The airflow collating device of the dyeing machine further comprises an adjusting unit 7, the adjusting unit 7 comprising a gear box 71 and a transmission rod, the gear box 71 being located outside the cylinder 1, the gear box 71 being connected to the transmission rod, the transmission rod being connected to the connecting shaft 62, the gear box 71 having internally a transmission gear which controls the rotary movement of the gear box 72.

Through practice, the rotatable angle range of the connecting shaft 62 is 0-60 degrees, so that a better finishing effect can be realized.

Because the gear tube row 51 is fixed on the connecting shaft 62, the connecting shaft 62 can rotate at multiple angles under the control of the adjusting handle 73, so that when the raw material is replaced by the fabric with different thicknesses, different fabric finishing effects can be controlled by adjusting the angle of the gear tube row 51. Meanwhile, when washing water, the airflow pushes the fabric to impact the tooth tube row 51 of the finishing unit 5, so that the fabric can be fully contacted with the washing water, and sewage can flow away quickly, thereby improving the cleaning efficiency during washing water.

The tooth pipe 511 has a bend, and a sharp projection formed by the bend is directed toward the inner wall of the cylinder 1, and the bend prevents the tooth pipe 511 from interfering with the inside of the cylinder 1 within an angular range in which the finishing function can be exerted. The projection of the plane formed by the row of toothed tubes 51 in the horizontal direction covers the swinging hopper spout 86 of the dying machine, so that the fabric ejected from the swinging hopper spout 86 can fall completely onto the row of toothed tubes 51. The toothed pipe 511 is cylindrical, the tail end of the toothed pipe 511 is semi-spherical, the diameter of the toothed pipe 511 is equal to that of the tail end of the toothed pipe 511, and the cylindrical and semi-spherical shapes can better protect the fabric and prevent the fabric surface from being damaged because the surface of the toothed pipe 511 is smooth. The number of the gear tube rows 51 is equal to that of the swinging hopper nozzles 86 of the dyeing machine, and each gear tube row 51 correspondingly finishes the fabric sprayed out from each swinging hopper nozzle 86.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
