[0002] Dyeing is one of the common processing methods for fabrics. Dyeing can give fabrics different colors and improve the aesthetic value of fabrics. The current conventional dyeing method is usually to set up a container, pour the prepared dye into the container, and then immerse the fabric in the container. After soaking and stirring, the fabric is taken out of the container, and then the fabric is sent for drying, color fixing and other steps. However, in the dyeing process, the dye water level in the container needs to reach a certain height, that is, a large amount of dye is required at one time, and the preparation of the dye is troublesome. In addition, when dyeing some fabrics with lower weaving density, the amount of dye absorbed by the fabric per unit area is limited. However, in order to ensure the color of the fabric after dyeing, the concentration of the dye needs to be guaranteed, which is easy to cause waste of dye.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

The dyeing module includes a shell 14 located above the frame 1, a liquid inlet 6 is provided on the side wall of the shell 14, a booster pump 7 connected to the liquid inlet 6 is provided on the shell 14, and a plurality of nozzles 8 are fixedly connected to the bottom surface of the shell 14, the booster pump 7 is connected to the nozzle 8, and the nozzle 8 corresponds to the through hole 5.

[0030] Specifically, four supporting legs are integrally formed at the bottom end of the frame 1, and a circulation device for recycling the dye solution is arranged on one side of the frame 1. The liquid outlet 3 and the liquid inlet 6 are respectively connected to the input end and the output end of the circulation device through pipes. The liquid outlet 3 and the liquid inlet 6 are located on the same side of the frame 1, so that the liquid inlet 6 and the liquid outlet 3 are conveniently connected to the circulation device. Support rails are integrally formed on both sides of the top surface of the frame 1. The shell 14 is located on the top surface of the support rails. A gap for the cloth to pass through is formed between the bottom surface of the shell 14 and the top surface of the frame 1. The support plate 4 is embedded in the top surface of the frame 1. The top surface of the support plate 4 is flush with the top surface of the frame 1, the cross-sections of the through hole 5 and the nozzle 8 are both square, the booster pump 7 pressurizes the dye liquid entering the shell 14 to ensure that the dye liquid flowing out of the nozzle 8 can smoothly penetrate the cloth, thereby ensuring the dyeing effect of the cloth, the dye liquid penetrating the cloth falls from the through hole 5, flows out from the liquid outlet 3, and is re-filled into the liquid inlet 6 after treatment, so that the dye liquid is recycled, thereby improving the utilization rate of the dye liquid, and the dye liquid can completely penetrate the cloth below the nozzle 8 by means of pressurization, thereby reducing the amount of dye liquid prepared and used, thereby avoiding the waste of dye liquid.

[0031] like Figure 3 , Figure 4 As shown, a plurality of nozzles 8 are arranged at intervals along the width direction and the length direction of the frame 1, respectively. A sleeve 9 is sleeved on the nozzle 8. The sleeve 9 covers the through hole 5 on the vertical projection plane. The length of the sleeve 9 is greater than the distance from the nozzle 8 to the support plate 4. Specifically, in this embodiment, along the length direction of the frame 1, the nozzles 8 are divided into four groups, each group includes a plurality of nozzles 8 arrayed along the width direction of the frame 1, the number of the first group, the second group, and the third group of nozzles 8 are four, and the number of the fourth group of nozzles 8 is three. On the vertical projection plane, with the width direction of the frame 1 as the X-axis, the inner cavity projection of the first group of nozzles 8 and the inner cavity projection of the second group of nozzles 8 are completely misaligned on the X-axis, and the inner cavity projection of the third group of nozzles 8 and the inner cavity projection of the fourth group of nozzles 8 are completely misaligned on the X-axis. They are completely misaligned on the X-axis, and the inner cavity projection of any nozzle 8 in the third group and the inner cavity projection of the corresponding nozzle 8 in the second group partially overlap on the X-axis.

The nozzles 8 are dispersed, and some of the nozzles 8 are made to spray dye during dyeing, so as to achieve local dyeing of the cloth. The inner wall of the sleeve 9 fits the outer wall of the nozzle 8, and a cylinder for driving the sleeve 9 is fixedly connected in the shell 14. The sleeve 9 descends under the push of the cylinder. When the nozzle 8 sprays dye, the sleeve 9 prevents the dye from splashing, thereby ensuring the accuracy of local dyeing of the cloth and avoiding the effect of the cloth after dyeing from being inconsistent with the expected pattern.

[0032] like Figure 1 , Figure 3As shown, a filter bucket 10 is provided in the through hole 5, and the top of the filter bucket 10 is embedded in the top surface of the support plate 4, and the bottom end of the filter bucket 10 is located in the recovery chamber 2. A receiving bucket 11 is provided in the recovery chamber 2, and the inner cavity width of the receiving bucket 11 gradually decreases from top to bottom. The receiving bucket 11 is detachably connected to the frame 1, and a flow channel 12 is provided on the inner bottom surface of the receiving bucket 11, and the flow channel 12 is connected to the liquid outlet 3. Specifically, the filter bucket 10 is a rectangular parallelepiped with an open top, and the filter bucket 10 is composed of a stainless steel wire filter mesh. The top of the filter bucket 10 is fixedly connected to a limiting frame, and the limiting frame is embedded in the top surface of the support plate 4. The top surface of the limiting frame is flush with the top surface of the support plate 4, and the limiting frame is used to limit the filter bucket 10 from falling, thereby improving the connection strength between the filter bucket 10 and the support plate 4, and the dye liquid falling from the through hole 5 passes through The filter hopper 10 intercepts the debris that is washed off the cloth by the dye solution, reduces the debris that falls into the receiving hopper 11, and prevents the debris from accumulating in the flow channel 12 and the liquid outlet 3, thereby reducing the maintenance and cleaning frequency of the dyeing equipment. The cross-section of the combination of the inner cavity of the receiving hopper 11 and the flow channel 12 is trapezoidal, and the receiving hopper 11 is slidably connected in the recovery chamber 2. An opening is provided on the side of the frame 1 away from the liquid outlet 3, and the cross-sectional area of ​​the opening is larger than the cross-sectional area of ​​the receiving hopper 11. A cover plate is detachably connected to the side wall of the frame 1 by bolts, and the cover plate covers the opening. When the recovery chamber 2 needs to be cleaned, the cover plate is removed, the receiving hopper 11 is taken out of the recovery chamber 2, and the receiving hopper 11 is cleaned outside the frame 1, thereby improving the efficiency of cleaning and maintaining the dyeing equipment.

[0033] like Figure 1 , Figure 3 , Figure 4 As shown, a light board 13 is inlaid on the top surface of the rack 1, and the light board 13 is located on one side of the shell 14. Specifically, a guide groove is opened on the top surface of the supporting guide rail, and a stopper is integrally formed on the top surface of the supporting guide rail. The guide groove starts from one end of the supporting guide rail and ends at the stopper. A slider is integrally formed on the bottom surface of the shell 14, and the slider is slidably connected in the guide groove. The shell 14 and the stopper are detachably connected by bolts. When it is necessary to clean and maintain the shell 14 and the support plate 4, the pipeline connected to the surface of the shell 14 is removed, and the shell 14 is slid along the length direction of the rack 1 to disassemble the shell 14 and expose the support plate 4, which further improves the efficiency of cleaning and maintaining the dyeing equipment. The light board 13 is located on the side of the stopper away from the guide groove. The cloth passes over the rack 1 in the direction from the shell 14 to the light board 13. When the dyed cloth passes over the light board 13, the light of the light board 13 is convenient for checking the dyeing effect of the cloth.

[0034] Embodiment 2: A control process of a cloth dyeing device, applied to the above-mentioned cloth dyeing device, comprises the following steps:

[0035] S1, laying the cloth on the top surface of the frame 1, and the cloth moves forward;

[0036] S2, the cloth stops moving forward, the sleeve 9 descends, and the cloth is pressed on the support plate 4;

[0037] S3, the dye liquid pressurized by the booster pump 7 flows out from the nozzle 8, and the dye liquid penetrates into the through hole 5 from the fabric;

[0038] S4, the dye liquid falls onto the receiving hopper 11 after passing through the filter hopper 10, then flows into the flow channel 12 along the receiving hopper 11, and finally flows out from the liquid outlet 3;

[0039] S5, sleeve 9 is lifted and the fabric moves forward;

[0040] S6. Repeat S2 to S5.

[0041] In S4, the dye liquid flowing out of the liquid outlet 3 is processed and then re-injected into the liquid inlet 6. A control system is provided in the shell 14. In S3, the control system inputs signals to each independent nozzle 8 in a preset sequence, wherein when the signal received by the nozzle 8 is true, the nozzle 8 is opened, and when the signal received by the nozzle 8 is false, the nozzle 8 is closed.

[0042] Specifically, before the cloth enters the lower part of the shell 14, the part of the cloth to be dyed is first treated with a bulking agent. In this embodiment, ST-2 bulking agent is used to make the yarn in this part of the cloth more fluffy, which is convenient for the dye liquid to penetrate the yarn, ensure the dyeing effect of the cloth, and improve the color fastness after dyeing. Because the weaving density of the cloth itself is relatively low, the dye liquid and the bulking agent can easily penetrate the cloth. In S2, all sleeves 9 are lowered, and valves are provided between any nozzle 8 and the booster pump 7. In S3, according to the preset pattern, the control system opens the corresponding valve to spray the dye in the corresponding nozzle 8. Liquid is used to partially dye the cloth, enriching the pattern content that the dyeing equipment can process. In S5, while the nozzle 8 is lifted, the cloth moves forward and enters the next cycle from S2 to S5, and in the next S2, when the cloth stops, the distance the cloth moves forward is equal to the width of the nozzle 8. In the repeated cycle, as the cloth moves forward, the nozzle 8 forms a complete pattern on the cloth. The dye liquid is initially filtered when it falls from the filter bucket 10. The dye liquid that first flows out of the liquid outlet 3 flows into the liquid inlet 6 again after secondary filtration, water removal, and verification to ensure the dye content in the dye liquid.

[0043] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
