[0025] A handle 8 is fixed to the top surface of the box cover 2, which makes it easy to lift the box cover 2, thereby providing convenience for loading and unloading the box cover 2. Feed holes 9 are provided on the left and right sides of the dyeing box 1, and the feed holes 9 are connected to the top surface of the dyeing box 1.

[0026] See also Figures 1 to 4 The mounting mechanism 3 includes two rectangular bins 301 fixed opposite to the box cover 2, and a rotating rod 302 is rotatably connected between the inner walls on the left and right sides of the rectangular bin 301. Two tooth grooves 303 are provided on the front and rear sides of the dyeing box 1. A gear 304 that is conducive to the meshing of the tooth grooves 303 is fixed on the outer peripheral wall of the rotating rod 302. A driving component 7 for driving the rotating rod 302 to rotate is provided on the rectangular bin 301. When in use, the fabric is passed through the left feed hole 9 and the fabric is passed through the right feed hole 9. At this time, the lower surface of the fabric contacts the upper surface of multiple support rollers 6. The box cover 2 is further placed on the top of the dyeing box 1, and the two The opposite sides of the rectangular bin 301 are respectively slidably connected to the front and rear sides of the dyeing box 1. At this time, the gear 304 slides into the tooth groove 303 and meshes with it, thereby playing a certain guiding and limiting role for the box cover 2. The driving component 7 further controls the rotating rod 302 to drive the gear 304 to rotate, thereby driving the box cover 2 to move downward. When the box cover 2 moves downward, the support plate 4 will drive the lower pressure roller 5 to insert into the dyeing box 1. The bottom surfaces of multiple lower pressure rollers 5 contact the upper surface of the fabric, and then cooperate with the support roller 6 to make the fabric distributed in the dyeing box 1 in a zigzag wave shape, so that the fabric can be better immersed in the dye for dyeing.

[0027] The dyeing box 1 is disposed between the two rectangular bins 301 and the two are slidably connected. Two movable holes 305 for the gears 304 to pass through are provided on one side of the rectangular bin 301 facing the dyeing box 1 .

When the box cover 2 moves downward, the support plate 4 drives the lower pressure roller 5 to insert into the inside of the dyeing box 1. The bottom surfaces of the multiple lower pressure rollers 5 contact the upper surface of the fabric, and then cooperate with the support rollers 6 to make the fabric distributed in the dyeing box 1 in a sawtooth wave shape, so that the fabric can be better immersed in the dye for dyeing;

[0033] (2) When it is necessary to control the up and down adjustment of the box cover 2, the worm 705 is rotated, the worm 705 drives the worm wheel 701 to rotate, the worm wheel 701 drives the rotating rod 302 to rotate, and the rotating rod 302 can drive the gear 304 to rotate and then drive the box cover 2 to move up and down. After adjustment, the height position of the box cover 2 can be maintained by the self-locking between the worm 705 and the worm wheel 701. When it is necessary to remove the box cover 2 or to move the box cover 2 up and down significantly, the screw 706 can be rotated, the screw 706 drives the U-shaped plate 704 to cooperate with the guide block 703 and the guide groove 702 to move downward, and then drives the worm 705 to move downward inside the adjustment hole 707, so that the worm 705 is no longer engaged with the worm wheel 701. At this time, the rotating rod 302 loses the self-locking characteristics of the worm wheel 701 and the worm 705, and can directly drive the box cover 2 to move up and down through the handle 8, further facilitating the operation of the device.
