[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The interception groove 42 on the movable plate 41 is precisely matched with the interception push plate 12 on the dye vat body 1. When the sealing cover 11 is rotated to open or close, the interception push plate 12 moves accordingly and cooperates with the interception groove 42. When the staff opens the sealing cover 11, the movable plate 41 moves downward to the opening of the dye vat body 1 due to the lack of the obstruction of the interception push plate 12, which is convenient for the staff to operate;

[0018] The cloth discharging roller 410 is mounted on the bearing plate 43, and its height is adapted to the internal structure of the dyeing vat body 1. After the cloth is dyed, the cloth can be pulled out of the dyeing vat smoothly and at a uniform speed, avoiding the problem of inconsistent dyeing depth caused by uneven cloth discharging speed;

[0019] 2. The mobile bearing assembly 4 is connected to the fixed base assembly 2 through the mobile frame 31, wherein the slide bar 34 and the slide rod 35 of the mobile frame 31 are slidably connected to the moving block 44, so that the bearing plate 43 and the cloth discharge roller 410 thereon and other components can be flexibly moved in the horizontal direction;

[0020] The positioning pin 38 on the buffer bottom plate 36 cooperates with the fixing hole 45 of the moving block 44 to fix the moving bearing assembly 4. After the sealing cover 11 is opened, the movable plate 41 slides on the surface of the moving frame 31 through the moving block 44. When sliding to the lower end of the moving frame 31, the staff can insert the positioning pin 38 into the fixing hole 45 to stabilize the entire moving bearing assembly 4 at the set position, thereby preventing the position of the cloth from being offset due to equipment vibration or other external factors during the printing and dyeing process, thereby ensuring the consistency and stability of the printing and dyeing effect;

[0021] 3. The sponge squeezing plate 67 in the squeezing assembly 6 is driven by the double-headed output motor 63 to squeeze the cloth on the cloth output roller 410 through the linkage of the threaded rod 64, the slider 65 and the connecting arm 66. The double-headed output motor 63 can accurately control the output torque and speed, so that the threaded rod 64 rotates smoothly, thereby driving the slider 65 to move up and down along the surface of the movable stand 62. The connecting arm 66 converts this linear motion into a vertical squeezing motion of the sponge squeezing plate 67, which can adjust the squeezing force of the cloth. During the squeezing process, regardless of whether the thickness of the cloth is uniform, it can ensure that a relatively consistent squeezing force is applied to each part of the cloth, so that the dye in the cloth is more evenly distributed, effectively avoiding the problem of dyeing color difference caused by uneven squeezing, and improving the qualified rate and quality stability of printing and dyeing products;

[0022] 4. In the fixed base assembly 2, the mounting groove 24 of the base platform 21 provides an accurate mounting position for the fixing frame 22. The dye vat body 1 is mounted on the base platform 21 through the fixing frame 22. This mounting method is simple, intuitive and easy to operate. During the equipment installation process, the installer only needs to place the fixing frame 22 along the mounting groove 24 and perform simple fixing to complete the preliminary installation of the dye vat body 1, which greatly shortens the installation time. At the same time, the positioning cylinder 23 is connected to the fixing frame 22. After the installation is completed, the positioning cylinder 23 can be used to fine-tune the positions of the fixing frame 22 and the dye vat body 1 to ensure the accuracy of the installation position of the dye vat body 1, facilitate the subsequent connection and debugging work with other components, and enable the entire equipment to be quickly put into use;

[0023] The guide balancing assembly 5 plays a key role in the stable operation of the equipment. During the operation of the equipment, especially when the load-bearing plate 43 and its upper components move, the tooth column 53 slides in the sleeve 52, and through the engagement with the gear 56 and the coordinated action of the balance frame 54 and the balance rod 55, the center of gravity and force conditions of the load-bearing plate 43 can be adjusted in real time. When the equipment is subject to external interference or the internal components move unbalancedly, the guide balancing assembly 5 can keep the load-bearing plate 43 level and stable, preventing the equipment from tilting, getting stuck or even being damaged due to the shift of the center of gravity.

[0055] The working principle and use process of the present invention are as follows: the movable plate 41 and the carrying plate 43 in the movable carrying assembly 4 constitute the main carrying part of the cloth, and the cloth discharging roller 410 is used to place the cloth to be dyed or receive the dyed cloth. The staff can open the sealing cover 11, and the sealing cover 11 drives the interception push plate 12 to move during the movement. At this time, the interception push plate 12 leaves the interception groove 42, so that the movable plate 41 moves downward and drives the cloth discharging roller 410 to move to the outlet of the dyeing tank. At this time, the movable block 44 squeezes the interception block 310, and the staff can insert the positioning pin shaft 38 into the fixing hole 45 to adjust the movable plate 41. The movable plate 41 is fixed. When the cloth needs to be sent out of the dye vat, the push cylinder 47 can drive the movable plate 41 to move along the slide rail 48 (sliding is achieved through the slide block 49), so that the movable plate 41 is close to the dye vat body 1. The frame assembly 3 provides a stable moving track and positioning support for the mobile bearing assembly 4. The baffle 1 32 and baffle 2 33 at both ends of the mobile frame 31 and the slide bar 34 and slide rod 35 on the surface form a sliding connection structure with the moving block 44 of the mobile bearing assembly 4. During the movement, the slide bar 34 provides horizontal guidance, and the slide rod 35 ensures vertical stability, so that the mobile The bearing assembly 4 can be smoothly moved above the dye vat and accurately positioned. The squeezing assembly 6 is used to squeeze the cloth after dyeing to remove excess dye. When the double-head output motor 63 is working, it drives the threaded rod 64 to rotate. Since the threaded rod 64 is threadedly connected with the slider 65 and the slider 65 is in contact with the surface of the mobile stand 62, the slider 65 can only move up and down along the mobile stand 62. The movement of the slider 65 is converted into a vertical squeezing movement of the sponge squeezing plate 67 through the connecting arm 66, thereby applying squeezing force to the cloth on the cloth output roller 410. By controlling the output parameters of the double-head output motor 63, the cloth output roller 410 is pressed against the cloth output roller 411. The number can accurately adjust the extrusion force to achieve effective extrusion of fabrics of different materials and thicknesses. The guide balance component 5 mainly ensures the stability of the equipment during operation. The tooth column 53 slides in the sleeve 52. When the load-bearing plate 43 and its upper components are subjected to uneven force or the center of gravity is shifted due to fabric movement or other factors, the tooth column 53 and the gear 56 engage with each other through the groove 57 on the surface of the sleeve 52, driving the balance rod 55 to rotate on the balance frame 54, thereby adjusting the posture of the entire load-bearing plate 43 to keep it balanced and stable, avoiding the impact of printing and dyeing quality or damage to the equipment due to shaking or tilting of the equipment.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
