Description

Flow guiding device for fabric dyeing machine with nozzle

Technical field

The invention relates to a flow guiding device with a nozzle, which is an improvement of a swinging device of a dyeing machine, and belongs to the technical field of printing and dyeing equipment.

Background technique

The ordinary high-temperature liquid dyeing machine includes a nozzle and a storage tank, and the like, so that the fabric circulates in the dyeing machine in a continuous loop shape. The fabric falls into the storage tank after passing through the nozzle, and the length of the fabric treated by the dyeing machine is generally longer than that of the storage tank, so that the fabric generally forms a stacked form in the storage tank. The accumulated fabric is squeezed and pushed by the weight of the fabric in the storage tank, and sent to the dyeing nozzle at one end of the storage tank until the fabric is sprayed by the dyeing nozzle device, and then returned to the storage. The other end of the cloth trough forms a pile and begins another cycle. However, the fabric does not undergo systematic accumulation during the process of dropping into the storage tank, and the space of the storage tank is often not used efficiently. Therefore, later models added a one-way swing device to increase the efficiency of fabric accumulation in the storage tank.

The sling in the dyeing machine is generally located at the exit of the duct, and swings back and forth continuously during the dyeing process. The fabric passes through a full-spray nozzle and then into the guide tube. When the fabric is discharged from the guide tube, it will fall onto the moving part of the swing bucket due to the suction of the center of gravity, and will be moved in the same manner, and will swing left and right before falling to the storage tank. Through this special walking mode, the fabric is continuously dropped to the right and left on the storage tank, and a layer of regular stacking is formed in an orderly manner, so that the fabric walks more smoothly during the dyeing process. The stacked cloth is then again sucked into the guide tube in the next cycle and dyed again. However, the above system has some hidden dangers. Although the turbulent bucket helps the fabric to accumulate on average, when the woven fabric is tight and heavy, the regular and repeated movement of the turret often makes the fabric repeat in the storage tank, and its repeatability even makes each segment naturally crease. The location remains the same. Due to the location of the crease The efficiency of the dyed liquid will be different from that of the unfolded position. When the position of the crease of the fabric is not relaxed during the operation, the position will be replaced or replaced, and the position will leave permanent or stain marks that cannot be removed. In general, to break through the repeated regular movements in the dyeing machine, a feasible method is to cooperate with the turbulent flow generated by the dyeing cycle to interfere with the repeated action on the machine. The disadvantage of this method is that it is necessary to increase the spray volume of the dye liquor, so that the dyeing machine bath increases the energy consumption and the discharge problem. In order to further improve the above technology, the present invention has been specifically proposed.

Summary of the invention

The purpose of the application of the present invention is to make up for the deficiencies of the prior art. In the dyeing of fabrics, a flow guiding device with a nozzle is used to break the creases on the fabric and the flat fabric by using a high flow rate water flow, and the fabric can be The circulation inside the dyeing machine is smoother and avoids entanglement of the fabric. The cloth discharging device used in the application of the present invention will replace the original swinging bucket, and the entire guiding cloth tube can swing to the left and right, thereby causing the effect of the one-way swinging bucket, thereby replacing the conventional swinging bucket.

Further, the spraying direction of the second nozzle is sprayed obliquely upward of the downstream of the guide tube, and the inclined surface of the deflector faces the second nozzle.

Further, the second nozzle is composed of a single nozzle or a plurality of nozzle combinations.

As shown in FIG. 1-2, the flow guiding device for a fabric dyeing machine with a nozzle according to the application of the present invention has a guide tube 1 , and the two ends of the guide tube 1 are an inlet 11 and an outlet 12, and the inlet 11 and the cloth are provided. The rolls are connected and the fabric is driven by a cloth roll to a set of first nozzles 21 which are unidirectionally sprayed by one side, the set of nozzles being primarily used for dyeing and providing for moving fabric movement. The fabric which becomes heavier due to the increased water content will pass through a curved section 13 to a horizontal pipe which is provided with a trough-shaped guide groove 3 and a second nozzle 22 and a deflector 14 at the bottom. A groove 15 is disposed between the second nozzle 22 and the deflector 14. This combination reflects the dye solution sprayed from the second nozzle 14 to cause the dye solution to flow from the lateral direction to the longitudinal direction toward the bottom of the fabric. The high flow turbulence of the sapphire diversion trough 3 forms a turbulent flow of three points of convergence, which acts as a cloth and shovel for the fabric, thereby reducing the chance of creases on the fabric and allowing the fabric to be dyed. The cycle inside the machine is smoother. Then, the fabric will be discharged at the outlet 12 of the guide tube that oscillates left and right, and is continuously dropped to the right and left on the storage tank, and a layer of regular stacking is formed in order to make full use of the storage space in the dyeing machine. . The stacked fabrics are pushed to the other side of the dyeing machine by the U-shaped storage trough at the bottom of the dyeing machine due to their own weight. Finally, the fabric will be rolled up again by the cloth drum and a dyeing cycle will be carried out. ring.

In the application of the present invention, the dyeing liquid of the first nozzle 21 is mainly ejected from one side in one direction to prevent the fabric from being restrained from being scattered; however, the nozzle gap is not completely sealed to avoid an influence on the dyeing effect. The flow guiding device provided in the horizontal pipe section of the curved section 13 has a second nozzle 22, a baffle 14 and a sapphire diversion channel 3, the baffle 14 is disposed downstream of the second nozzle 22, and the second nozzle 22 The ejected high-flow dyeing liquid is incident on the deflector 14, the angle of the baffle 14 is designed to reflect a large amount of water, and the reflected water is combined with the water generated by the palm-shaped diversion groove 3 to form a turbulent flow. The area where the turbulence is the largest is called the unfolding area, where the fabric is blown up and made into a cloth and a shovel. The premise requires a large amount of water to make a turbulent flow, achieving an ideal tumbling and shovel. Cloth effect.
