[0002] Traditional intermittent fabric jet, gas-liquid (airflow) dyeing machines mostly use cloth-lifting rollers and nozzles (dye solution or airflow) as power to pull the fabric for circulation. Some machines also eliminate cloth-lifting rollers and only rely on nozzles to pull the fabric for circulation, but the pulling force is always diagonally backward or horizontally backward. When the existing gas-liquid jet dyeing machines lift the fabric, the tension generated by the fabric is too large due to the long constraint path during the operation of the fabric, and the friction with the metal wall causes scratches, making it difficult to lift the fabric and causing scratches on the fabric surface.

The structure, proportion, size, etc. illustrated in the drawings of this specification are only used to match the content disclosed in the specification, so that people familiar with this technology can understand and read, and are not used to limit the limiting conditions that can be implemented in the utility model, so they have no technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect that can be produced by the utility model and the purpose that can be achieved, should still fall within the scope of the technical content disclosed in the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of narration, and are not used to limit the scope that can be implemented. The change or adjustment of its relative relationship should also be regarded as the scope that can be implemented in the utility model without substantially changing the technical content.

[0023] Example 1, please refer to Figures 1 to 3 , a gas-liquid jet dyeing machine, a main cylinder 1 of the gas-liquid jet dyeing machine is provided with an inclined chute 2, the inclined chute 2 is located below the outlet of the cloth guide pipe 406, and a U-shaped cloth storage trough 3 is also provided in the main cylinder 1. The U-shaped cloth storage trough and the inclined chute 2 can increase the cloth capacity in combination. A gas-liquid combination nozzle device 4 is vertically arranged above the main cylinder 1. The fabric is sucked in by the gas-liquid combination nozzle, sprayed out through the swing of the guide bend pipe and falls into the inclined chute 2 that slides downward obliquely, and then falls into the U-shaped cloth storage trough. A certain volume of fabric is stacked in these two cloth storage troughs in an orderly manner. The two ends of the fabric are connected to form a fabric ring for continuous circulation, and the fabric cycle is controlled by the fabric speed and the length of the fabric ring. The main cylinder 1 is connected with conventional components such as a heat exchanger, a main pump and a fan. The dyeing principle is the same as that of the prior art and will not be repeated here.

[0024] Gas-liquid combination nozzle device 4 comprises housing 401. Housing 401 below is provided with dye liquid atomizing nozzle 402, and multiple dye liquid atomizing nozzles 402 are connected on annular tube 403 by threaded joint, and preferred dye liquid atomizing nozzle 402 quantity is 3-10. The angle between dye liquid atomizing nozzle 402 and vertical direction is 0-90 °. Dye liquid atomizing nozzle 402 below has lower cloth guide ring 404, lower cloth guide ring 404 and annular tube 403 are connected on flange seat 405, flange seat 405 is installed on housing 401 below, and upper cloth guide ring 408 is pressed on housing 401 by flange seat 405. Fabric enters nozzle interior from lower guide ring, and multiple dye liquid atomizing nozzles 402 on fabric circumference dye fabric simultaneously, and atomized dye liquid and fabric exchange area are large, and permeability is strong, and completes the uniform dyeing process of dye.

[0025] A cloth guide tube 406 is provided above the housing 401, an air flow nozzle 407 is provided below the cloth guide tube 406, an upper cloth guide ring 408 located inside the air flow nozzle 407 is provided at the lower entrance of the housing 401, and the air flow nozzle 407 sprays air flow in a vertical direction, thereby pulling the fabric to move along the upper cloth guide ring 408 in a vertical direction and pass through the cloth guide tube 406. The upper cloth guide ring 408 has a trumpet-shaped opening below and a straight line above. The air flow sprayed by the air flow nozzle 407 passes through the outer side of the upper cloth guide ring 408 to form a vertical upward air flow, and the air flow nozzle 407 is a Laval nozzle. The high-speed airflow generated by the airflow nozzle 407 moves vertically upward under the guidance of the upper cloth guide ring 408, generating a vertical upward traction force on the fabric, so that the fabric can circulate in the main cylinder 1. During the traction process, it is mainly affected by gravity, and the friction and restraint force generated by other components are small, ensuring the fabric circulation cycle. At the same time, the fabric can be expanded and creases can be eliminated. While the fabric is being pulled by the airflow, it exchanges with the dye liquid through the dye liquid atomizing nozzle 402, completing the process of dyeing the fabric with dye. The lower cloth guide ring 404 and the upper cloth guide tube 406 are both made of polytetrafluoroethylene.

[0026] The fabric guide tube 406 is connected to the swing mechanism, which includes a swing arm 409 and a rotating pair 410 driven by the swing arm 409. The rotating pair 410 is connected to the fabric guide tube 406 and drives the fabric guide tube 406 to rotate back and forth. The rotating pair 410 is composed of conventional components such as a bearing, a bearing seat and a sealing ring. The upper end of the fabric guide tube 406 is bent, and the lower end of the fabric guide tube 406 is vertically set. The maximum bending angle of the upper end of the fabric guide tube 406 relative to the vertical direction is 90°. The swing mechanism swings completely left and right electrically, so that the fabric falls into the inclined fabric storage groove in the form of a swing. The bending of the rear end of the fabric guide tube 406 can control the direction in which the fabric is thrown out.

[0027] The dye atomizing nozzle 402, the air flow nozzle 407 and the fabric guiding elbow are arranged in sequence in space to form a three-in-one structure, so that the fabric is subject to a smaller constraint path during operation, the influence of tension is reduced, and the friction between the fabric and the metal wall is reduced.

[0028] The housing 401 is connected with an air duct 411, which is connected to the airflow nozzle 407. The air duct 411 is used for the airflow nozzle 407 to generate a high-speed jet airflow, and is arranged in the main cylinder 1, integrated with the inner cavity of the gas-liquid combined nozzle jacket, and can also be separated and connected through a branch pipe.

[0029] Embodiment 2, the gas-liquid jet dyeing machine can also be a tubular gas-liquid jet dyeing machine. Its principle is the same as that of embodiment 1, and will not be repeated here.

[0030] Different from the prior art, the gas-liquid combined nozzle device and the gas-liquid jet dyeing machine of the utility model use vertical airflow to pull the fabric into circular motion, adopt a single circulating power source, reduce the restraining force on the fabric, avoid fabric abrasion, and improve the dyeing effect.

[0031] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
