[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. When soaking the fabric, control the electric telescopic rod to work, so that the mobile guide rollers can stretch the top of the fabric to both sides, so that the two sides of the fabric are stressed and the middle of the fabric is stretched. The fabric can be spread out to avoid uneven dyeing caused by folding of the fabric during soaking and dyeing. Stretching the fabric can reduce wrinkles and creases during the dyeing process. Wrinkles and creases may affect the penetration and distribution of dyes, resulting in uneven dyeing or spots. Stretching the fabric can ensure that the dye can evenly cover the entire fabric surface;

[0018] 2. By setting up a movable guide roller to open the top of the fabric, the gaps between the fibers of the fabric can be enlarged. During soaking, the dye is more likely to fully contact the fabric, and the soaking and dyeing of the fabric is more efficient. The fabric can be more fully exposed to the dye, and the dye can penetrate into all parts of the fabric more evenly, reducing the phenomenon of uneven dyeing, which helps to obtain a more consistent and beautiful dyeing effect;

[0019] 3. Drive the electric telescopic rod to make the dye sucked in the liquid absorption bag spray out through the water spray pipe, so that the dye is sprayed to the top of the stretched fabric, which speeds up the flow of the dye. By accelerating the impact of the dye on the fabric, the time for the dye to contact and penetrate the fabric can be shortened, thereby improving the dyeing efficiency. This is especially important for production lines that need to complete dyeing tasks quickly, which helps to reduce production cycles and increase output;

[0020] 4. After the fabric is stretched, its fiber structure becomes looser. At this time, accelerating the impact of the dye can more effectively promote the dye to penetrate into the fabric, which can not only increase the depth of dyeing, but also make the fabric color more uniform and full;

[0021] 5. Accelerating the flow rate of the dye to impact the fabric can help reduce uneven dyeing. When the dye impacts the fabric at a faster speed, it can more effectively cover various parts of the fabric surface, thereby reducing the appearance of color differences and color spots.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-4The present invention provides a technical solution: a mobile guide mechanism for a dyeing immersion tank, including a dyeing immersion tank 1 and a guide component 3. Mobile guide rollers 2 are arranged on the left and right sides of the dyeing immersion tank 1.

[0034] Wherein, the guide component 3 comprises:

[0035] A fixed frame 301 is fixedly connected to the middle of the top of the dyeing immersion tank 1, and auxiliary guide rollers 302 are arranged on the left and right sides of the fixed frame 301. A fixed cross plate 303 is fixedly connected to the middle of the top of the fixed frame 301, and the front and rear sides of the bottom of the fixed cross plate 303 are fixedly connected to a fixed guide box 304. A connecting frame 305 is fixedly connected to the bottom of the fixed guide box 304, and a guide roller frame 306 is rotatably connected to the inner side of the connecting frame 305. When the fabric passes through the bottom of the guide roller frame 306, the guide roller frame 306 can guide and support the fabric.

[0036] When the fabric needs to be immersed and dyed, the fabric is passed through the movable guide roller 2 and the auxiliary guide roller 302 in turn and connected to the external winding device. At this time, the top of the fabric passes through the guide roller frame 306 on the bottom connecting frame 305 of the fixed guide box 304, which can support the fabric and guide the moving direction of the fabric. By setting up the fixed frame 301, it can be avoided that large pieces of dye particles precipitated at the bottom directly contact the fabric and cause the color of the dye to be different, thereby ensuring the safety of the fabric during immersion dyeing.

The electric telescopic rod 401 can drive the lifting plate 402 to rise and fall in the fixed guide box 304 when working.

[0039] It also includes a liquid spraying assembly 5, which is composed of a supporting connecting plate 501, a liquid suction bag 502, a water spraying pipe 503, a water suction pipe 504, and a movable squeezing plate 505.

[0040] The supporting connecting plate 501 is fixedly connected to the side of the fixed guide box 304 away from the inner wall of the dyeing immersion tank 1, the liquid absorption bag 502 is fixedly connected to the top of the supporting connecting plate 501, the water spray pipe 503 is fixedly connected to the bottom of the liquid absorption bag 502, the water absorption pipe 504 is fixedly connected to the bottom of the left and right sides of the liquid absorption bag 502, and the movable squeezing plate 505 is fixedly connected to the inner side of the lifting plate 402. The liquid absorption bag 502 can absorb the dye in the dyeing immersion tank 1 through the water absorption pipe 504.

[0041] Rectangular slide grooves are provided on the front and back of the fixed guide box 304, and the telescopic cylinder 403 and the movable extrusion plate 505 are slidably connected to the rectangular slide grooves. When the lifting plate 402 is lifted or lowered, it can drive the telescopic cylinder 403 and the movable extrusion plate 505 to lift or lower.

[0042] Rotating wheels are provided on the left and right sides of the sliding storage plate 408, and guide grooves corresponding to the rotating wheels are provided on the front and rear sides of the lifting storage rack 406. The sliding storage plate 408 is slidably connected to the guide grooves in the lifting storage rack 406 through the rotating wheels. A limiting groove for accommodating the movement of the sliding storage plate 408 is provided at the bottom of the lifting storage rack 406. The sliding storage plate 408 is slidably connected to the inner side of the limiting groove. The sliding storage plate 408 can be lifted and lowered in the lifting storage rack 406, and the moving guide roller 409 is synchronously controlled to perform lifting and lowering operations.

[0043] The telescopic end of the electric telescopic rod 401 passes through the fixed horizontal plate 303 and the top of the fixed guide box 304 and extends into the fixed guide box 304 to be fixedly connected to the top of the lifting plate 402. The electric telescopic rod 401 can drive the lifting plate 402 to perform lifting work when working.

[0044] The bottom of the water spray pipe 503 passes through the supporting connecting plate 501 and extends to the bottom of the supporting connecting plate 501. A one-way valve 1 is arranged in the water spray pipe 503, and a one-way valve 2 is arranged in the water suction pipe 504. The input end of the one-way valve 1 is the top, and the input end of the one-way valve 2 is the side away from the liquid absorption capsule 502. The liquid absorption capsule 502 can absorb the dye in the dyeing immersion pool 1 into the liquid absorption capsule 502 through the water suction pipe 504, and spray the dye through the water spray pipe 503 at the bottom of the liquid absorption capsule 502.

[0045] When the fabric is soaked, the electric telescopic rod 401 is controlled to work, so that the electric telescopic rod 401 pushes the lifting plate 402 to descend when working. At this time, when the lifting plate 402 moves downward, the telescopic cylinder 403 drives the rotating block 404 to descend, so that the telescopic cylinder 403 is stretched, and at the same time, the rotating block 404 rotates in the rotating connecting frame 407, and at the same time, the rotating connecting frame 407 is forced to push the sliding storage plate 408. At this time, the guide pulley on the sliding storage plate 408 slides in the lifting storage frame 406, and at the same time, the sliding storage plate 408 moves downward inside the lifting storage frame 406, so that the moving guide roller 40 9 moves downward, at this time, the movable guide roller 409 contacts the top of the fabric, and as the movable guide roller 409 continues to move downward, the top of the fabric is squeezed downward, so that the movable guide roller 409 stretches the top of the fabric to both sides, so that the two sides of the fabric are stressed and the middle of the fabric is stretched, so that the fabric can be spread out to avoid folding of the fabric during soaking and dyeing to produce uneven dyeing. Stretching the fabric can reduce wrinkles and creases during the dyeing process. Wrinkles and creases may affect the penetration and distribution of the dye, resulting in uneven dyeing or spots. Stretching the fabric can ensure that the dye can evenly cover the entire fabric surface.

[0046] By setting up the movable guide roller 409 to open the top of the fabric, the gaps between the fibers of the fabric can be enlarged. During soaking, the dye is more likely to fully contact the fabric, and the soaking and dyeing of the fabric is more efficient. The stretched fabric can be more fully exposed to the dye, and the dye can penetrate into all parts of the fabric more evenly, reducing the phenomenon of uneven dyeing, which helps to obtain a more consistent and beautiful dyeing effect.

[0047] When the electric telescopic rod 401 controls the lifting plate 402 and the movable squeezing plate 505 to descend, the movable squeezing plate 505 descends to squeeze the top of the liquid absorption bag 502, so that the dye absorbed in the liquid absorption bag 502 is sprayed out through the water spray pipe 503, and the dye is sprayed to the top of the stretched fabric, thereby accelerating the flow speed of the dye. By accelerating the impact of the dye on the fabric, the time for the dye to contact and penetrate the fabric can be shortened, thereby improving the dyeing efficiency. This is particularly important for production lines that need to complete dyeing tasks quickly, which helps to reduce production cycles and increase output.
