As shown in fig. 1-10, the high-efficiency textile dyeing device comprises a first cloth conveying roller 1, a dyeing tank 3, a second cloth conveying roller 2, a dryer 4 and a winder 5 which are sequentially arranged along the conveying direction of cloth 0. The first cloth conveying roller 1 and the second cloth conveying roller 2 adopt conventional cloth conveying rollers, generally comprise an upper roller and a lower roller, and the upper roller and the lower roller are used for clamping and conveying the cloth 0 together to maintain enough tension of the cloth. The dyeing tank 3 is used for dyeing the cloth 0, the most conventional dyeing tank 3 is a square tank body, dye is injected into the tank body, and the cloth 0 passes through the dyeing tank 3 to be dip-dyed. The dryer 4 is used for drying the cloth 0, the conventional dryer 4 is a box, and a heating plate, a heating sheet and the like are arranged in the box. The winder 5 is used for winding the dried cloth 0, and various winding devices sold in the market can be adopted as the winder 5.

One of the differences of the present invention compared to conventional dyeing systems is that: as shown in fig. 2 to 4, the dyeing tank 3 is U-shaped, and the upper parts of both sides are respectively provided with a cloth inlet 6 and a cloth outlet 7. The U-shaped dyeing tank 3 can be used for completely submerging the cloth 0 under the condition of containing less dyes, the used dyes are less at each time, the dyes are saved, and the economy is better. In order to guide the advancing direction of the cloth 0, the dyeing tank 3 is provided with a cloth inlet guide roller 8 at a cloth inlet 6 and a cloth outlet guide roller 9 at a cloth outlet 7. Two corner parts in the dyeing tank 3 are respectively provided with a first in-tank guide roller 10 and a second in-tank guide roller 11.

The middle section of the bottom of the dyeing tank 3 is provided with an installation chamber 12, and a dyeing acceleration mechanism is arranged in the installation chamber 12 and used for accelerating dyeing and improving dyeing quality. The dyeing accelerating mechanism has a specific structure that, as shown in fig. 3 and 4, the dyeing accelerating mechanism comprises two end discs 13 which are parallel to each other, two groups of contact rods are arranged between the two end discs 13, and the two groups of contact rods are symmetrically distributed on the left side and the right side of the axis connecting line of the two end discs 13. Each set of contact rods comprises an upper contact rod 14 and a lower contact rod 15, the two ends of the upper contact rod 14 and the lower contact rod 15 are respectively connected with the two end discs 13, and the upper contact rod 14 and the lower contact rod 15 can be directly welded on the end discs 13 under normal conditions. Cloth 0 is worn out by a cloth outlet 7 by advancing cloth mouth 6 and getting into in the dyebath 3 and passing through in proper order between last contact arm 14 and the lower contact arm 15 of entering cloth deflector roll 8, first inslot deflector roll 10, two sets of contact arms, second inslot deflector roll 11 and play cloth deflector roll 9 back. The dyeing accelerating mechanism can swing back and forth along the axes of the two end discs 13 under the driving of the driving component, so that the upper contact rod 14 and the lower contact rod 15 can alternately pull the cloth 0.

After the arrangement, when the cloth feeding device is operated, the first cloth feeding roller 1 and the second cloth feeding roller 2 are actively operated to clamp and feed the cloth 0, and the cloth 0 is fed and kept to have enough tension. The cloth feeding guide roller 8, the cloth discharging guide roller 9, the first in-groove guide roller 10 and the second in-groove guide roller 11 mainly play a role in guiding the cloth 0 to convey the cloth along a U-shaped path. After the dye is injected into the dyeing bath 3, the cloth 0 is dip-dyed while being conveyed. Compared with the traditional dye vat, the dyeing tank 3 is internally provided with the dyeing accelerating mechanism, and the end disc 13 of the dyeing accelerating mechanism moves along with the end disc 13 in the process of back-and-forth rotation, namely clockwise and anticlockwise staggered rotation as shown in figure 3, so that the cloth 0 is straightened, pulled and shaken up and down. Because cloth 0 itself possesses certain elasticity, such mode can impel the fibre gap switching of cloth 0 to play the effect of pump suction dyestuff, make the dyestuff even, quick infiltration to cloth 0 inside. Meanwhile, certain impact force can be generated between the cloth 0 and the dye in the up-and-down fluctuation process, the combination of the cloth 0 and the dye is rapidly promoted, and the dye is enabled to fully soak the cloth 0. Therefore, compared with the traditional dye vat, the dyeing tank 3 has higher dyeing efficiency and better dyeing effect.

Regarding the driving problem of the reciprocating swing of the dyeing accelerating mechanism, the invention can adopt the method that the end part of the end disc 13 is provided with a connecting shaft, the connecting shaft extends out of the mounting chamber 12 and is connected with a stepping motor, and the end disc 13 is driven to rotate back and forth through the positive and negative rotation of the stepping motor. However, the stepper motor is expensive and the maintenance cost is high. To this end, the present invention preferably provides that, as shown in fig. 4, a short pin 16 is provided on an outward facing plate surface of one of the end plates 13, and the short pin 16 is mounted on an inner side wall of the mounting chamber 12 through a bearing. And a connecting shaft 17 is arranged on the outward disc surface of the other end disc 13, and the connecting shaft 17 extends out of the mounting chamber 12 and is connected with a driving assembly.

Of course, it is also possible to replace the guide sleeve 21 with a member that performs the same function, such as a guide groove.

The transmission rod 20 is matched with the guide sleeve 21 and is arranged in the guide sleeve 21 in a penetrating mode. The upper end of the transmission rod 20 is hinged with the lower end of the connecting rod 19, and the lower end of the transmission rod 20 is provided with a bolt 22. The upper end of the connecting rod 19 is hinged with the disc surface of the rotary disc 18 close to the edge, and the rotary disc 18 is driven by a dyeing motor fixedly arranged on the outer side wall of the mounting chamber 12. A side swing rod 23 is fixedly arranged on one side of the connecting shaft 17, the side swing rod 23 extends along the radial direction of the connecting shaft 17, and a strip-shaped hole 24 is formed in the side swing rod 23 along the length direction. The bolt 22 on the transmission rod 20 is matched with the strip-shaped hole 24 and penetrates through the strip-shaped hole 24. In order to improve the stability of the movement of the inserted pin 22 in the strip-shaped hole 24, it is preferable that an inverted U-shaped connecting clip 25 is fixedly disposed at the lower end of the transmission rod 20, the inserted pin 22 is disposed between two side edges of the connecting clip 25, and the connecting clip 25 is clipped outside the side swing link 23.

After the driving component is adopted, the upper contact rod 14 and the lower contact rod 15 of the dyeing accelerating mechanism can be driven to rotate and swing around a connecting line of the centers of the end discs 13 by a dyeing motor, so that the cloth 0 is repeatedly stretched and fluctuated in the dyeing tank 3. The specific operation of the drive assembly can be seen in fig. 5-7.

Since the elasticity of the fabric is different, that is, the fabric 0 has different elasticity, the upper contact rod 14 and the lower contact rod 15 have different limits of travel for stretching the fabric 0 when contacting the fabric 0. Thus, if the power transmission of the drive assembly to the upper and lower contact bars is completely rigid, it may either result in malfunction of the dyeing motor or cause damage to the cloth 0. For this purpose, as shown in fig. 8, the transmission rod 20 of the drive assembly according to the invention is preferably formed by an upper sleeve section 26 and a lower plug section 27. A vertical square hole 28 is arranged in the sleeve section 26, and the square hole 28 extends upwards from the lower end face of the sleeve section 26. The upper end face of the insertion section 27 is provided with a square rod 29 matched with the square hole 28, and the square rod 29 penetrates through the square hole 28. The square rod 29 is further sleeved with a spiral spring 30, the upper end of the spiral spring 30 is connected with the lower end face of the sleeve section 26, and the lower end of the spiral spring 30 is fixedly connected with the upper end face of the plug-in section 27. With such a configuration, the length of the transmission rod 20 has a certain buffering margin, and can be extended or shortened, and the stress between the cloth 0 and the upper contact rod 14 and the lower contact rod 15 has a certain buffering range in the process of contacting the cloth. Thereby preventing the phenomenon that the dyeing motor or the cloth 0 is damaged.

The rubber sleeve and the rotatable stainless steel core shaft can further buffer the stress of the cloth 0, and the risk of damaging the cloth 0 is reduced on the premise of ensuring the dyeing quality. In order to prevent the cloth 0 from directly contacting with the convex parts of the inner walls of the dyeing tank 3 at the two sides of the installation chamber 12, as shown in fig. 3, the inner walls of the top surface and the bottom surface of the dyeing tank 3 at the two sides of the installation chamber 12 are provided with limit rollers 31, and the cloth 0 is positioned between the limit rollers 31 at the top surface and the bottom surface of the installation chamber 12. In addition, in order to further improve the dyeing speed, a plurality of ultrasonic transducers 32 are uniformly arranged in the dyeing tank 3, the ultrasonic transducers 32 are connected with an ultrasonic generator, and the ultrasonic generator drives the ultrasonic transducers 32 to emit ultrasonic waves so as to promote the combination of the dye and the cloth 0.
