Description

Flow guiding device with overflow nozzle

Technical field

The utility model relates to a flow guiding device with an overflow nozzle, which is an improvement of a swinging device for a liquid dyeing fluffing machine, and belongs to the technical field of printing and dyeing fabric 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 an endless 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, the latter models have added a one-way swing device, which increases the efficiency of the accumulation of fabric 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 will first pass through a full-spray nozzle and then enter the guide tube. When the fabric is discharged from the guide tube, it will fall to the moving part of the swing bucket due to the suction of the center of gravity, and be driven to move in the same way. Swing left and right before falling to the storage slot. Through this special walking mode, the fabric is continuously dropped on the storage tank, and a layer of regular lamination is formed in order to make the fabric walk more smoothly during the dyeing process. Then, the stacked cloth will be sucked into the guide tube again in the next cycle and dyed again.

However, the above system has some hidden dangers. Although the swinging bucket helps the fabric to accumulate on average, when the fabric weaving structure is tight and heavy, the regular and repeated movement of the swinging bucket often makes the fabric repeat in the storage tank, and the repetition is repeated. Sex even keeps the crease position naturally formed in each segment unchanged. Since the efficiency of accepting the dye solution at the crease position is different from that of the non-folding position, when the position of the crease of the fabric is not relaxed, displaced or replaced during operation, the position will leave a permanent mark that cannot be removed or Dye marks. 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 amount of dyeing liquid, so that the dyeing machine bath increases the energy consumption and emissions. The existing spray technology on the dyeing machine with some designs can significantly improve the problem of fabric dyeing marks, but when applied to fabrics that require a soft texture, such as a terry cloth dyeing machine, it is not ideal to maintain the softness of the dyed fabric. degree.

technical problem

The purpose of the utility model is to make up for the insufficiency of the existing fabric dyeing technology to effectively maintain the fluffy soft texture of the dyed fabric, and to provide a flow guiding device with an overflow nozzle when the fabric is dyed.

Technical solution

The flow guiding device mainly comprises two parts: the first part is a special nozzle which uses a non-omnidirectional (asymmetric) jet dyeing liquid in the outer diameter of the swinging section (the curved section is curved). The fabric is pushed into the swing pipe; the second part is to install a series of low-pressure spray holes at the bend diameter in the curved section of the swing bucket to spray the dye liquor on the fabric at a low pressure. This can more effectively break the creases on the fabric and the flattened fabric, avoiding excessive squeezing of the fabric by the high-pressure dyeing liquid and entanglement and loss of fluffy soft texture. The use of low-pressure showers can provide a more uniform and gentle dyeing solution. On the fabric, it also reduces water consumption and makes the fabric circulate more smoothly in the dyeing machine.

Specifically, the flow guiding device with the overflow nozzle according to the present invention includes a swinging bucket, and a semi-ring nozzle is arranged on the curved section of the swinging bucket, in the curved curved section of the swinging bucket. A plurality of low pressure spraying holes are provided at the position of the curved diameter surface.

Further, the semi-ring nozzle is a conical nozzle comprising two inner and outer rings, and one half of the annular gap between the inner ring and the outer ring (ie, 180° circumference) is closed, and the remaining half of the circumferential annular gap is The special semi-ring nozzle is a pipe for applying the dyeing liquid to the fabric in the first stage, and the overall size is not limited, and the size of the annular gap is not limited.

Further, the position of the closed section of the annular gap corresponds to the inner diameter of the curved section of the swing bucket, and the annular gap position of the open section corresponds to the outer diameter of the curved section of the swing bucket. Such nozzle design has three important advantages, including: 1. Since the jet dyeing liquid is only ejected from the outer diameter position of the swinging section of the swinging bucket, the inner diameter of the curved curved section of the swinging bucket does not apply the spraying pressure to the fabric, thus avoiding The fabric is excessively squeezed to lose the soft texture; 2. The inner and outer bends form an asymmetrical jet, which produces a complex thrust on the fabric, which acts as a flap and a shovel to avoid creases in the fabric; Since only the low-pressure jet dyeing liquid is only passed through the half annular gap that is opened, the water consumption can be further reduced.

Further, the inner diameter of the curved section of the swinging bucket is provided with a plurality of low-pressure spraying holes, which can play two important functions, including: 1. Applying the dyeing liquid to the fabric in the second stage in a lower pressure spraying manner; The lower pressure spray pattern creates a gentle thrust on the surface of the fabric, propelling the fabric within the swing, while also avoiding the fabric being over-squeezed and losing its fluffy softness.

Further, the low-pressure spray holes have a shape of a circle and an elongated shape, and the size and shape are not limited.

Further, the cross section is an arc shape and a swing bucket having a curved section, and the curvature is not limited, and the curvature, the number and the position of the curved section are not limited.

Further, the flow guiding device with the overflow nozzle further comprises a rotating shaft disposed at the bottom of the swinging bucket, and the rotating shaft is connected to the swinging bucket through the connecting block.

Further, the rotating shaft is driven to rotate by the driving device, and then the swinging block is driven to swing by the connecting block to the left and right, and the type thereof is not limited.

Beneficial effect

The flow guiding device with the overflow nozzle of the utility model can maintain the soft texture of the fabric, reduce the occurrence of creases on the fabric, make the dyeing of the fabric more uniform, and can avoid the entanglement of the fabric, save investment time and manpower to fabric The entanglement of a large number of resources, reducing the cost of expenditure, especially suitable for endless continuous rope loop fabric dyeing machine to deal with fabrics requiring high soft texture, such as terry cloth.

Embodiments of the invention

The technical solutions described in the present invention are described below in conjunction with FIGS. 1-3 and the embodiments.

As shown in Fig. 1-3, the present invention is a flow guiding device for a dyeing machine 1 with a special nozzle. First, the fabric is driven by the dyeing machine 1, passes through the guide tube 3, enters the outer diameter 6 of the swinging section of the swinging bucket 2, and the inner diameter 7 of the swinging section, and the semicircular nozzle 5 is provided on the outer diameter 6 of the swinging section of the swinging bucket. The semi-annular nozzle 5 is mainly used for applying the dyeing liquid and pushing the fabric forward. At this time, the external water inlet sprays the low-pressure dyeing liquid on the fabric through a row of low-pressure spraying holes 8 provided in the curved diameter 7 of the swinging section of the swinging bucket.

The technical scheme of the utility model combines the semi-ring nozzle 5 and the spray shower to supply the dye liquor and drive the fabric to move in the swing bucket 2, and the design can avoid the fabric being excessively squeezed and losing the fluffy soft texture and reducing the fabric. Creases appear on the fabric to make the dyeing of the fabric more uniform and to avoid entanglement of the fabric. The fabric which becomes heavier due to the increased water content will go to the straight section 9 of the swing bucket via the outer diameter 6 of the swinging section and the inner diameter 7 of the swinging section. Then, the fabric will be discharged at the swing outlet 10 of the left and right swings, and will be 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 swing of the swing bucket 2 needs to be realized by the rotary shaft 11 which can swing left and right, and the connection of the swing bucket 2 and the rotary shaft 11 is realized by the joint block 12. The stacked cloth is pushed to the other side of the dyeing machine by the U-shaped storage slot at the bottom of the dyeing machine due to its own weight. Finally, the endless continuous loop fabric is rolled up by the fabric roll and a dyeing cycle is repeated.

In the present invention, the semi-annular nozzle 5 is mainly responsible for spraying and pushing the fabric forward. The dye liquor is sprayed onto the fabric at a lower pressure through a row of low pressure spray holes 8 provided in the inner diameter 7 of the curved section. Since the half annular slit opened by the half ring nozzle 5 is located at the outer diameter 6 of the curved portion, the spray liquid will blow the fabric from the position of the outer diameter 6 of the curved portion to the inner diameter of the curved portion 7, and the result is in the half ring. An asymmetrical driving force is formed in the ring of the nozzle 5. It relies on the combination of the asymmetric nozzle driving force and the low-pressure shower driving force to prevent the fabric from being excessively squeezed and losing the soft texture, which can prevent the fabric from being restrained and not scattered, and can reduce the fabric entanglement and affect the dyeing effect. .

It should be understood that the above description including the drawings is not intended to limit the technical solution. In fact, any improvement of the technical solution by the same or similar principle, including the size, shape, and material change of the structure, And replacement of functionally similar components are within the technical solution claimed by the present invention.
