[0002] In the field of denim dyeing process, progressive dyeing can give denim unique and richly textured color effects, which are deeply loved by consumers. At present, there are various ways in practice for the progressive dyeing of denim, and the common one is to dye the denim after it is made into clothes. Among them, the dip dyeing method is an important means to realize the progressive dyeing of clothes, and its principle is to control the time of different positions of clothes immersed in dye to achieve the effect of gradient color. In specific operation, it usually needs to be immersed for several times, for example, the clothes are first immersed in the dye, and then the clothes are controlled to fall a certain distance each time, and the time of each falling is accurately controlled, so as to realize the ideal gradient color. However, the existing dip dyeing method and related equipment for denim clothes dyeing have many shortcomings. The traditional dip dyeing equipment lacks precision in controlling the immersion depth and time of clothes, and it is difficult to realize fine control of the progressive dyeing effect, resulting in uneven final dyeing effect. Moreover, the existing equipment is not integrated with a dehydration function, and the dyed clothes need to be transferred to a dehydration device for processing, which not only increases the complexity of the process flow, but also easily damages the dyed clothes during the transfer process, affecting product quality.

When it is necessary to control the falling of the jeans clothing, the pushing assembly one pulls the sliding sleeve, drives the abutting peg to move, and then drives the abutting rod one and the abutting rod two, so that the tooth block two is aligned with the tooth block one to form a complete gear, the driving motor drives the driving gear to rotate, drives the driving disc one to rotate through the abutting tooth ring one, and controls the whole control device to descend along the abutting rack. When reaching the specified position, the pushing assembly one is reversely operated to separate the tooth block two from the tooth block one. At the same time, the tooth block three of the driving disc two is abutted with the abutting rack.

The device innovatively integrates dyeing and dehydration functions. In the process of driving mechanism driving the falling of clothes for dyeing, the fixed plate will extrude the extrusion rod, so that the extrusion rod drives the butt joint to fall and butt with the clamping plate 1 and the clamping plate 2. When the driving mechanism falls to the lowest position and starts to move up for dyeing, the extrusion rod gradually approaches the clothes. At this time, the second pushing assembly pushes the clamping plate 1 and the clamping plate 2, drives the sliding frame and the butt joint to move to the clothes and clamps the clothes. With the clothes moving up, the extrusion rod extrudes and dehydrates the clothes. This design avoids the complicated process of transferring the dyed clothes to the dehydration device, not only simplifies the process, but also reduces the risk of damaging the dyed clothes during the transfer process, and improves the product quality. 3. The structural design of the device fully considers the diversified dyeing needs of different styles, sizes and materials of jeans clothes. For example, the hanging rods are arranged transversely and elastic member 1 is arranged between the hanging blocks, which can adapt to the hanging of clothes of different sizes. The sliding frame in the positioning mechanism is connected by spring 1, the clamping plate 1 and the clamping plate 2 can slide in the mounting groove of the sliding frame, and the movement thereof is controlled by the second pushing assembly, so that the clamping position and force of the clothes can be flexibly adjusted according to the specific conditions of the clothes. The different tooth block combinations of the driving disc 1 and the driving disc 2 and the cooperation mode with the butt teeth can accurately control the dyeing process according to the different requirements of different materials for dyeing depth and time, so as to meet the diversified dyeing needs.

[0034] When the control device 2 drives the finished garment to fall to the specified position, and then the pushing assembly one 2235 pushes the sliding sleeve 2233 to move, and the abutting bolt 2234 pulls the abutting rod one 2244 and the abutting rod two 2256 respectively through the sliding sleeve 2233, when the abutting rod one 2244 is pulled, the tooth block two 2243 and the tooth block one 2242 are separated, and when the abutting rod two 2256 is pulled, the pressing block 2255 moves, the pressing of the extrusion surface one 2253 is reduced, and then the elastic member two 2254 pushes the tooth block three 2252 to extend the fixed disc two 2251, at this time, the driving motor 2232 drives the driving disc one 224 and the driving disc two 225 to rotate synchronously through the driving gear 2231, and the rotation direction of the driving disc one 224 and the driving disc two 225 is opposite, when the tooth block one 2242 in the driving disc one 224 engages with the abutting rack 112, the tooth block three 2252 in the driving disc two 225 does not engage with the abutting rack 112, because the number of abutting teeth on the surface of the tooth block one 2242 is more than that of the tooth block three 2252, so when the tooth block one 2242 engages with the abutting rack 112, the driving mechanism 22 will descend a certain distance, then the tooth block three 2252 will engage with the abutting rack 112 to drive the driving mechanism 22 to move upward a small distance, the upward moving distance of the tooth block three 2252 is less than the downward moving distance, through this cycle of falling process, the uniformity of the gradual dyeing of the finished garment can be greatly improved.

[0035] In the process of falling of the driving mechanism 22, the pressing rod 217 will be pressed through the fixed plate 221, and the pressing rod 217 will drive the butt joint 218 to fall through the pressing, and the butt joint 218 will be opposite to the clamping plate one 214 and the clamping plate two 215 in the process of falling, and the clamping head 2182 in the butt joint 218 will be pressed into the sliding block 2181 when the clamping tooth is opposite to the clamping head 2182, and the clamping tooth will clamp the butt joint 218 after the pressing rod 217 loses the downward pressure, so that the butt joint 218 cannot be pulled back to the original position by the spring three 219, and after the driving mechanism 22 falls to the lowest position for dyeing, the driving motor 2232 drives the driving gear 2231 to rotate reversely, so that the control device 2 is moved upward again for dyeing, and because the pressing rod 217 is limited and cannot move upward, the pressing rod 217 will gradually approach the clothes, and after the pressing rod 217 approaches the clothes, the pushing assembly two 216 will push the clamping plate one 214 and the clamping plate two 215 respectively, and the sliding frame 211 and the butt joint 218 are driven to move to the clothes by the clamping plate one 214 and the clamping plate two 215, and the clothes are clamped by the movement of the butt joint 218, and the clothes are pressed and dewatered by the pressing rod 217 when the clothes move upward, and after the driving mechanism 22 drives the clothes to move to the highest position, the pushing assembly two 216 pulls the clamping plate one 214 and the clamping plate two 215 respectively, and the clamping plate one 214 and the clamping plate two 215 are separated from the sliding frame 211 by pulling, and then the spring three 219 pulls the butt joint 218 to reset the pressing rod 217.
