[0002] Dyeing and finishing is a comprehensive process for scouring, dyeing, printing and finishing of textile materials such as fibers, yarns and fabrics. In order to smoothly carry out the dyeing, printing and finishing processes, the textile materials must first be scourged to remove impurities. Dyeing is a process in which natural dyes or synthetic dyes react physically and chemically with textile fibers to color them.

[0003] At present, when dyeing fabrics, the fabrics are usually placed directly into the dyeing liquid for immersion dyeing. During the immersion dyeing process, there is no measure to press the fabrics, so that the dyeing liquid cannot fully and quickly penetrate into the fabrics, resulting in slow dyeing efficiency and uneven dyeing. Secondly, the dye in the dyeing and finishing equipment is stationary during the dyeing process, and the pigment in the dye is prone to precipitation, resulting in uneven contact between the fabric and the dye, reducing the dyeing efficiency of the grey cloth, and also reducing the dyeing and finishing quality of the fabric.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a flat width dyeing and finishing device, referring to Figure 1 , including a dyeing tank 1 and a drying device for fixing the color of the fabric, and also including a plurality of guide rollers 2 that are rotatably connected, the plurality of guide rollers 2 are horizontally arranged and parallel to each other, and the fabric is dyed in the dyeing tank 1 under the action of the tail traction device and the plurality of guide rollers 2 and then enters the drying device for fixing the color.

[0023] Reference Figure 1 A stirring drum 3 is rotatably connected to the dyeing tank 1 through a rotating shaft, and the stirring drum 3 is parallel to the guide roller 2. A stirring motor is fixed on the dyeing tank 1, and the output shaft of the stirring motor is coaxially fixed on the rotating shaft of the stirring drum 3 and drives the stirring drum 3 to rotate. A plurality of stirring blades 4 are fixed to the outer wall of the stirring drum 3, and the stirring blades 4 extend along the length direction of the stirring drum 3. The stirring blades 4 are evenly distributed along the circumference of the stirring drum 3. The side walls of the stirring blades 4 are located on the circumference coaxial with the stirring drum 3, and a stirring groove 5 is formed between two adjacent stirring blades 4 and the outer wall of the stirring drum 3. The opening of the stirring groove 5 gradually becomes smaller along the side close to the axis of the stirring drum 3, and the stirring groove 5 is an arc-shaped inclined structure along the circumference of the stirring drum 3. Several stirring grooves 5 have the same shape and are inclined in a straight direction. An abutting roller 6 parallel to the stirring drum 3 is rotatably connected to the dyeing tank 1, and the abutting roller 6 abuts on the side walls of the adjacent stirring blades 4, which has a certain beating and squeezing effect on the fabric.

[0024] Reference Figure 1 and Figure 2The abutting roller 6 includes an abutting shaft 7 rotatably connected to the dyeing tank 1 and an abutting cylinder 8 sleeved outside the abutting shaft 7. A plurality of abutting springs 9 are fixed to the outer wall of the abutting shaft 7. The abutting springs 9 are evenly distributed outside the abutting shaft 7, and the length direction of the abutting springs 9 is arranged along the radial direction of the abutting shaft 7. One end of the abutting spring 9 is fixed to the abutting shaft 7, and the other end is fixed to the inner wall of the abutting cylinder 8. The setting of the abutting roller 6 structure, on the one hand, plays a certain role in adjusting the tightness of the fabric, and on the other hand, meets the needs of fabrics of different thicknesses, ensuring that the outer wall of the abutting cylinder 8 is always in abutment with the side wall of the adjacent stirring blade 4.

[0025] Reference Figure 1 and Figure 2 A vertical partition 10 is fixed in the dyeing pool 1. The partition 10 divides the dyeing pool 1 into a dyeing chamber and a circulation chamber. The circulation chamber is located between the dyeing chamber and the drying device. The abutting roller 6 and the stirring drum 3 are parallel to the partition 10 and located in the dyeing chamber. The stirring blade 4 is partially located above the liquid surface. The stirring tank 5 is closed at both ends. The partition 10 is provided with a circulation tank 11 that passes through the partition 10. The side walls of the two adjacent stirring blades 4 abut against the upper and lower end surfaces of the opening of the circulation tank 11 and are used to close the circulation tank 11. The side walls of the stirring blades 4 have the same shape and structure as the upper and lower inner walls of the circulation tank 11 and abut against each other, which plays a certain sealing role. During the rotation of the stirring drum 3, when one of the stirring tanks 5 opens to the circulation chamber, the two adjacent stirring blades 4 abut against the upper and lower inner walls of the circulation tank 11, ensuring that only the dye liquid in the stirring tank 5 can move toward the circulation chamber.

[0026] Reference Figure 1 A baffle 12 parallel to the partition 10 is fixed in the dyeing chamber, and a squeezing roller 13 abutting against the side wall of the stirring blade 4 is fixed on the lower surface of the baffle 12. Part of the squeezing roller 13 is located below the liquid surface, and the part of the squeezing roller 13 and the stirring blade 4 used for squeezing the fabric is located above the liquid surface. The squeezing roller 13 and the stirring blade 4 work together to squeeze out excess moisture in the fabric. The length of the squeezing roller 13 and the baffle 12 is not less than the width of the fabric, so as to reduce the adsorption of impurities such as fibers suspended on the liquid surface onto the fabric.

[0027] Reference Figure 1 , Figure 2 and Figure 3A plurality of receiving grooves 14 corresponding to the stirring tank 5 are provided in the stirring drum 3, and a plurality of through holes 15 for connecting the stirring tank 5 and the receiving groove 14 are provided on the receiving groove 14. A cover plate 30 is slidably connected to the stirring drum 3 at the bottom of the stirring tank 5, and the cover plate 30 moves axially along the stirring drum 3. A plurality of connecting holes 16 corresponding to the through holes 15 are provided on the cover plate 30. When the through holes 15 are aligned with the connecting holes 16, the dye enters the receiving groove 14 along the connecting holes 16 and the through holes 15. A flushing device for controlling the sliding of the cover plate 30 and cleaning the hair scraps in the stirring tank 5 into the circulation chamber is provided on the stirring drum 3. The cover plate 30 slides, and the dye enters the receiving groove 14. Then, the dye in the receiving groove 14 is used to clean the stirring tank 5, so that the impurities adsorbed on the inner wall of the stirring tank 5 are flushed into the circulation chamber.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The side wall of the stirring blade 4 is provided with a sliding groove 17 along its length direction, and the receiving groove 14 is provided with a penetrating circulation hole 18 along the axial direction of the stirring drum 3. When the stirring drum 3 is rotating, the dye enters the stirring tank 5, and enters the receiving tank 14 along the through hole 15 and the connecting hole 16, and the excess dye flows back to the dyeing chamber along the circulation hole 18. Since impurities such as fiber dander float on the dyeing liquid, part of the dye in the stirring tank 5 drives impurities such as dander into the circulation chamber during the rotation process, and the dye in the circulation chamber flows back to the dyeing chamber after being filtered.

[0029] Reference Figures 1 to 4 The flushing device includes a sliding block 19 fixed to the side wall of the cover plate 30, the sliding block 19 is located in the sliding groove 17 and slides axially along the mixing drum 3 in the sliding groove 17, a sliding spring 20 is fixed in the sliding groove 17, one end of the sliding spring 20 is fixed to the inner wall of the sliding groove 17, and the other end of the sliding spring 20 is fixed to the sliding block 19 and aligns the through hole 15 with the connecting hole 16, one end of the cover plate 30 protrudes outside the mixing blade 4 and the mixing drum 3, and a driving block is fixed to the inner wall of the dyeing chamber close to the partition 10, and the driving block moves along the mixing drum 3. The thickness of the mixing drum 3 gradually increases in the rotating direction. When the mixing drum 3 rotates, the end of the cover plate 30 contacts the driving block and slides relative to the driving block. During the sliding process, the cover plate 30 is pushed to move, so that the through hole 15 and the connecting hole 16 are staggered until they are completely staggered. At this time, the dye liquid cannot continue to enter the storage tank 14, and part of the dye liquid mixed with impurities such as fibers is left in the mixing tank 5, which makes it easier for the dye liquid in the mixing tank 5 to drive the impurities into the circulation chamber, and the excess dye liquid flows back to the dyeing chamber along the circulation hole 18.

The flushing mechanism includes a switch plate 23 slidably connected in the switch groove 22. When the switch groove 22 rotates from the highest point to the lower point, the switch plate 23 slides in the switch groove 22 under the action of gravity and closes the opening of the flushing groove 21. The stirring drum 3 and the stirring blade 4 are provided with interconnected connecting grooves 26, and the connecting groove 26 connects the flushing groove 21 and the stirring tank 5. The flushing mechanism also includes a flushing component that uses the dye solution in the flushing groove 21 to clean the impurities on the inner wall of the stirring tank 5.

Under the action of the extrusion spring, one end of the extrusion column 25 protrudes outside the mixing drum 3, and an extrusion block is fixed on the inner wall of the dyeing chamber near the partition 10. The thickness of the extrusion block gradually increases along the rotation direction of the mixing drum 3. During the rotation of the mixing drum 3, the end of the extrusion column 25 gradually abuts against the extrusion block and slides on the extrusion block. Under the action of the extrusion block, the extrusion column 25 is pushed to move, and the pressure in the extrusion groove 24 and the scouring groove 21 increases, pushing the dye in the extrusion groove 24 along the connecting groove 26 to flush the impurities on the inner wall of the mixing tank 5, and flushing the impurities into the circulation chamber.

[0032] Reference Figure 1 and Figure 2 The drying device includes a vertically arranged drying box 27, the upper and lower ends of the drying box 27 are opened, the upper end of the drying box 27 is a feeding port, and the lower end is a discharging port.

[0034] The implementation principle of the embodiment of the present application is as follows: the fabric is dyed in the dyeing tank 1. During the dyeing process, the abutment roller 6 and the stirring blade 4 rotate, which are used to stir the dye solution on the one hand and beat the fabric on the other hand to facilitate the dyeing of the fabric and improve the quality of dyeing. During the rotation of the stirring drum 3, suspended impurities enter the stirring tank 5, and excess dye solution flows back into the dyeing chamber. Part of the dye solution drives the impurities into the circulation chamber to avoid adsorption on the fabric.
