[0001] The utility model relates to the technical field of polyester fabric dyeing and finishing, in particular to a polyester fabric low-water dyeing and finishing device. Background Art

[0002] The dyeing and finishing process is to use dyeing and finishing technology to perfectly reproduce our favorite colors and patterns on the blank, so as to make the fabric more artistic. This process mainly includes four processing steps: refining, dyeing, printing and finishing of raw silk and fabrics.

[0003] During the dyeing and finishing process, polyester fabric needs to be dyed before printing. Some existing dyeing and finishing devices dye the polyester fabric by transporting the polyester fabric to a dyeing tank for immersion. However, this dyeing method will absorb a large amount of water after the polyester fabric is dyed, resulting in a large amount of water waste when the fabric enters the subsequent process for drying. It is relatively inconvenient to use. For this reason, we propose a polyester fabric low-water dyeing and finishing device to solve or improve the above problems. Utility Model Content

[0018] See also Figure 1-4, including a dyeing bin 1, a supporting foot 2 is fixed at the bottom of the dyeing bin 1, and a plurality of supporting feet 2 are symmetrically fixed at the bottom of the dyeing bin 1, and the plurality of supporting feet 2 are used to support the main body of the device and ensure the stability of the device during operation, and a drain pipe is fixed at the bottom of the dyeing bin 1 to facilitate the discharge of the liquid inside the dyeing bin 1, and an upper pressing roller 9 is rotatably installed on the inner surface of the dyeing bin 1 through a rotating shaft, and two groups of the upper pressing roller 9 are symmetrically installed on the inner surface of the dyeing bin 1, and a lower pressing roller 20 is rotatably installed on the inner surface of the dyeing bin 1 through a rotating shaft, and two groups of the lower pressing roller 20 are symmetrically installed on the inner surface of the dyeing bin 1, and the lower pressing roller 20 is located on one side of the bottom of the upper pressing roller 9, and the surface of the lower pressing roller 20 is parallel to the upper pressing roller 9. The spacing between the surfaces of the rollers 9 is relatively small, and a support frame 11 is fixed on the top of the dyeing bin 1. The inner surface of the dyeing bin 1 is rotatably installed with a support roller 10 through a rotating shaft. The support roller 10 is located on the bottom side of the support frame 11. Two groups of support rollers 10 are symmetrically installed on the inner surface of the dyeing bin 1, and a slide groove 14 is opened on the top of the support frame 11. The drive motor 3 is fixed to the surface of the dyeing bin 1, and the bidirectional threaded rod 8 is rotatably installed on the inner surface of the dyeing bin 1 through a bearing. The output shaft of the drive motor 3 passes through the inner surface of the dyeing bin 1 and the top end is fixed to one end of the rotating shaft of the bidirectional threaded rod 8. The drive motor 3 can drive the bidirectional threaded rod 8 fixed at the top of the output shaft to rotate. Two groups of threads in opposite directions are symmetrically installed on the inner surface of the dyeing chamber 1, and two ends of the two-way threaded rod 8 are provided with two groups of threads in opposite directions. The first toothed belt wheel 4 is fixed to the top of one end of one group of two-way threaded rods 8, and the second toothed belt wheel 6 is fixed to the top of one end of the other group of two-way threaded rods 8. The synchronous toothed belt 5 is sleeved on the surface of the first toothed belt wheel 4 and the second toothed belt wheel 6 and is meshed with the first toothed belt wheel 4 and the second toothed belt wheel 6. When the driving motor 3 drives the other group of two-way threaded rods 8 to rotate, it will drive the fixed second toothed belt wheel 6 to rotate, and when the second toothed belt wheel 6 rotates, it will drive the meshed synchronous toothed belt 5 to rotate, and when the synchronous toothed belt 5 rotates, it will drive the meshed connected The first toothed belt pulley 4 rotates, and when the first toothed belt pulley 4 rotates, it will drive a fixed set of bidirectional threaded rods 8 to rotate. The blocking baffle 7 is slidably installed inside the dyeing bin 1. Two sets of bidirectional threaded rods 8 pass through the inside of the blocking baffle 7 and are threadedly connected to the blocking baffle 7. When the bidirectional threaded rod 8 rotates, it will drive the threaded blocking baffle 7 to move. There are two sets of blocking baffles 7 symmetrically and slidably installed inside the dyeing bin 1 and located at both ends of the bidirectional threaded rods 8. The surface of the blocking baffle 7 is provided with grooves for the upper pressure roller 9, the lower pressure roller 20 and the supporting roller 10 to pass through. The dyeing component is arranged inside the slide 14, and several groups of dyeing components are arranged inside the slide 14.

[0019] The dyeing component includes a slider 12 slidably installed in a slide groove 14, a rack 13 fixed on the surface of the slide groove 14, two groups of racks 13 are symmetrically fixed on the surface of the slide groove 14, a connecting rod 16 inserted in the slider 12, and a plurality of groups of connecting rods 16 are symmetrically inserted in the slider 12. One end of the top of the connecting rod 16 passes through the top of the slider 12, and a limit block 18 is fixed to the bottom of the connecting rod 16. The limit block 18 is located in the slider 12, and a slot for the limit block 18 to move is opened in the slider 12. One end of the limit block 18 passes through the surface of the slider 12 and is meshed with the rack 13. Because the limit block 18 is located inside the slider 12, when the limit block 18 is meshed with the rack 13, the limit block 18 can limit the position of the slider 12 through the rack 13, so that the position of the slider 12 is relatively fixed. When the connecting rod 16 moves, it will drive the fixed limit block 18 to move. When the limit block 18 moves to a certain position, it will be disengaged from the meshing connection with the rack 13. At this time, the limit block 18 no longer limits the position of the slider 12. The spring 17 is sleeved on the surface of the connecting rod 16. One end of the spring 17 contacts the surface of the limit block 18, and the other end contacts the inner surface of the slider 12. When the limit block 18 moves, The spring 17 will be squeezed to deform the spring 17. When there is no external force interference, the spring 17 will push the limit block 18 to move. The number of limit blocks 18 and springs 17 is the same as the number of connecting rods 16. The connecting block 15 is fixed to the top of the connecting rod 16. The connecting block 15 is fixed to the top of several groups of connecting rods 16 at the same time. When the connecting block 15 moves, it will drive several groups of fixed connecting rods 16 to move. The fan-shaped spray head 19 is fixed to the bottom of the slider 12. The top of the slider 12 is fixed with a liquid inlet pipe. The internal space of the liquid inlet pipe is connected to the internal space of the fan-shaped spray head 19. When it is necessary to spray polyester fabrics of relatively small size During shower dyeing, the connecting block 15 can be pulled to make the connecting block 15 drive the connecting rod 16 to move. When the connecting rod 16 moves, it will drive the fixed limit block 18 to move, so that the limit block 18 is disengaged from the meshing connection with the rack 13. At this time, the movable slider 12 can drive the slider 12 to move the fixed fan-shaped spray head 19, so as to adjust the spray position, thereby improving the adaptability of the dyeing component to polyester fabrics of different sizes. After the adjustment is completed, the connecting block 15 can be released to make the spring 17 push the limit block 18 to move and re-engage the limit block 18 with the rack 13, thereby completing the adjustment of the position of the slider 12, which is relatively convenient to use.

[0020] Working principle: when the polyester fabric needs to be dyed during the dyeing and finishing operation, the polyester fabric is passed through a group of upper pressing rollers 9 and lower pressing rollers 20, and the polyester fabric is squeezed by the upper pressing rollers 9 and the lower pressing rollers 20, so that the polyester fabric passes through the top of the two groups of support rollers 10 relatively flatly. At this time, the pressurized dyeing liquid is transported from the liquid inlet at the top of the slider 12 to the inside of the fan-shaped spray head 19 through a pipeline, so that the dyeing liquid can be sprayed from the bottom side of the fan-shaped spray head 19, thereby spraying and dyeing the polyester fabric on the top side of the support roller 10 on the bottom side of the support frame 11. Compared with the immersion method, spraying can control the amount of dyeing liquid used, thereby avoiding the polyester fabric from absorbing too much water, and avoiding the problem of a large amount of water resources being wasted when the polyester fabric enters the subsequent process for drying after absorbing too much water. It is relatively convenient to use. At this time, the polyester fabric after spraying and dyeing is passed from another group of upper pressing rollers 9 and lower pressing rollers 20. The upper pressing roller 9 and the lower pressing roller 20 can squeeze the polyester fabric by passing between the roller 9 and the lower pressing roller 20, thereby squeezing the excess dyeing liquid inside the polyester fabric and making it flow into the inside of the dyeing chamber 1, which is convenient for recycling and reuse, further reducing the waste of water resources. At the same time, when the polyester fabric to be dyed is small in size, a group of bidirectional threaded rods 8 can be driven to rotate by the driving motor 3, and a group of bidirectional threaded rods 8 can drive another group of bidirectional threaded rods 8 to rotate through the second toothed belt pulley 6, the synchronous toothed belt 5 and the first toothed belt pulley 4, so that the two groups of blocking baffles 7 are driven to move toward each other through the bidirectional threaded rods 8, thereby adjusting the passing width between the two groups of blocking baffles 7, so that the blocking baffle 7 can limit the position of the polyester fabric to avoid its deviation. At the same time, the blocking baffle 7 can reduce or prevent the waste of dyeing liquid caused by splashing the dyeing liquid to the outside of the polyester fabric during spraying, thereby further reducing the waste of water resources.
