[0014] The beneficial effects of the present invention are as follows: 1. The present invention is provided with a filter component. During dyeing, the water pump is started by controlling the PLC. When the water pump is started, the dye liquid in the No. 1 working box is sucked away through the connection of the first connecting pipe, the second connecting pipe and the liquid inlet pipe, and is discharged into the filter cavity through the connection of the third connecting pipe and the liquid outlet pipe. After being filtered through the filter screen, the dye liquid is discharged back into the No. 1 working box from the liquid outlet hole for use.

[0015] 2. The present invention scrapes impurities on the surface of the filter screen by a scraper, and drives the water wheel blades to rotate when the dye liquid enters the third connecting pipe and flows. The rotation of the water wheel blades drives the rotation of the first rotating shaft. When the first rotating shaft rotates, it drives the reciprocating screw to rotate through the pulley group.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, in an embodiment of the present invention, a dyeing device for washable RFID fabric tags includes a first working box 1, a second working box 2, and a guide roller 3. The guide roller 3 is installed inside the first working box 1, and multiple guide rollers are provided. The second working box 2 is provided on one side of the first working box 1. A filter assembly is provided inside the first working box 1. The filter assembly includes a water pump 4 disposed inside the No. 1 working box 1. The input and output ends of the water pump 4 are respectively connected to a first connecting pipe 5 and a third connecting pipe 8. The end of the first connecting pipe 5 away from the water pump 4 is fixedly connected to a second connecting pipe 6. A liquid inlet pipe 7 is installed on one side of the second connecting pipe 6. A liquid outlet pipe 9 is installed at one end of the third connecting pipe 8 away from the water pump 4, and a filter chamber 12 is provided below the liquid outlet pipe 9. The filter chamber 12 is opened inside the No. 1 working box 1, and a filter screen 11 is installed inside the filter chamber 12. Liquid outlet holes 13 are evenly provided on one side of the bottom of the filter chamber 12.

[0021] Existing: CN208965235U discloses an overflow dyeing machine intelligent dyeing equipment, which discloses the No. 1 working box 1 and No. 2 working box 2 proposed in this application document. This technical means will not be described in detail here; The inner cavities of the first connecting tube 5, the second connecting tube 6 and the liquid inlet tube 7 are connected, and the inner cavities of the third connecting tube 8 and the liquid outlet tube 9 are connected; During dyeing, the water pump 4 is started by controlling the PLC. When the water pump 4 is started, the dye liquid in the No. 1 working box 1 is sucked away through the connection of the first connecting pipe 5, the second connecting pipe 6 and the liquid inlet pipe 7, and is discharged into the filter cavity 12 through the connection of the third connecting pipe 8 and the liquid outlet pipe 9. After being filtered through the filter screen 11, it is discharged back into the No. 1 working box 1 from the liquid outlet 13 for use, and the dye liquid is circulated and filtered to reduce impurities such as fiber debris or agglomerated dyes adhering to the material surface or clogging the internal pores of the material, thereby ensuring the subsequent preparation effect of the RFID fabric tag.

[0022] like Figures 1 to 7 As shown, a plurality of liquid inlet pipes 7 are evenly arranged, and each liquid inlet pipe 7 is fixedly connected to the second connecting pipe 6 .

[0023] The liquid inlet pipe 7 is evenly arranged in the dye liquid up and down, and can absorb dye liquid at different heights to prevent the uneven distribution of impurities in the dye liquid due to temperature, concentration gradient or uneven stirring during the dyeing process. The liquid inlet pipes 7 at different heights can extract each layer of dye liquid at the same time, avoiding local impurity accumulation and improving the overall filtration efficiency.

[0024] like Figure 4 and Figure 5 As shown, a plurality of liquid outlet pipes 9 are evenly arranged, and each liquid outlet pipe 9 is fixedly connected to the third connecting pipe 8 .

[0025] A single liquid outlet pipe 9 may cause the dye solution to flow through a certain area of the filter screen 11, resulting in local clogging of the filter material or excessive filtration load; The plurality of liquid outlet pipes 9 can disperse the dye liquid flow rate, increase the contact area between the dye liquid and the filter screen 11 , reduce the risk of clogging of the filter screen 11 , and thus extend the service life of the filter screen 11 .

[0026] like Figure 4 and Figure 5 As shown, a drain pipe 10 is fixedly installed at the bottom end of each liquid outlet pipe 9.

[0027] The enlarging flow tube 10 is configured in a trumpet shape, and through the gradually expanding cross-section design, the sudden change in the flow velocity of the dye solution can be reduced, turbulence and eddy currents can be reduced, and the fluid flow can be made smoother.

[0028] like Figure 4 and Figure 5 As shown, a scraper 19 is slidably installed on the top of the filter 11, and a movable plate 18 is fixedly connected to the top of the scraper 19. The inner wall of the movable plate 18 is threadedly connected to a reciprocating screw rod 17. One end of the reciprocating screw rod 17 is connected to the first rotating shaft 15 through a pulley set 16. A water wheel blade 14 is fixedly installed on one end of the first rotating shaft 15, and the water wheel blade 14 is arranged inside the third connecting pipe 8.

[0029] When the dye liquor flows into the third connecting pipe 8, the water wheel blades 14 are driven to rotate. The rotation of the water wheel blades 14 drives the rotation of the first rotating shaft 15. When the first rotating shaft 15 rotates, the reciprocating screw 17 is driven to rotate through the pulley set 16. The rotation of the reciprocating screw 17 drives the movable plate 18 to move back and forth. The movement of the movable plate 18 drives the scraper 19 to slide back and forth on the top of the filter screen 11, pushing the impurities on the top of the filter screen 11 to the two sides of the filter screen 11, preventing impurities in the dye liquor (such as fiber debris and dye particles) from accumulating on the surface of the filter screen 11 to form a filter cake layer, hindering the subsequent dye liquor from passing through, resulting in a decrease in the filtration rate. The scraper 19 reciprocates to scrape off the impurities on the surface of the filter screen 11, and can peel off the filter cake layer in real time, restore the permeability of the filter screen 11, reduce the risk of clogging, and thus improve the filtration efficiency and stability.

[0030] like Figure 4 and Figure 5 As shown, slag collecting boxes 20 are provided on both sides of the filter screen 11 , and the two slag collecting boxes 20 are both slidably installed inside the No. 1 working box 1 .

[0031] The impurities scraped off by the scraper 19 are collected by the slag collecting box 20 for subsequent unified processing.

[0032] like Figure 5 As shown, one side of the slag collecting box 20 is provided with through holes 21 , and the through holes 21 are evenly distributed.

[0033] The dye liquid with impurities remaining in the slag collecting box 20 is filtered out through the through hole 21, thereby reducing the waste of dye liquid.

[0034] like Figure 5 、 Figure 6 and Figure 7 As shown, each entrainment tube 10 is fixedly connected by a second rotating shaft 24, one end of the second rotating shaft 24 is fixedly mounted with a second gear 23, one side of the second gear 23 is meshedly connected with a first gear 22, and the first gear 22 is fixedly mounted on one end of the reciprocating screw rod 17.

[0035] The liquid outlet pipe 9 is configured as a flexible pipe; When the reciprocating screw 17 rotates, it drives the first gear 22 to rotate, the rotation of the first gear 22 drives the rotation of the second gear 23, the rotation of the second gear 23 drives the rotation of the second rotating shaft 24, and the rotation of the second rotating shaft 24 drives the rotation of the enclosed flow tube 10, so that the dye liquid is discharged at multiple positions above the filter screen 11, so that the dye liquid forms a dynamic flow on the surface of the filter screen 11, avoiding local excessively high or low concentrations, promoting uniform distribution of impurities, reducing local overload of the filter screen 11, and helping to improve the stability of the filtration system.

[0036] like Figure 7 As shown, the inner wall diameter of the second gear 23 is ten N times the inner wall diameter of the first gear 22 , and N is a positive integer.

[0037] By means of the gear ratio of the first gear 22 and the second gear 23, the rotation speed of the second gear 23 is reduced, so that the liquid outlet pipe 9 and the drain pipe 10 rotate at a slow speed, making the movement smoother and improving the operating environment.

[0038] like Figure 5 and Figure 7 As shown, the second rotating shaft 24 is rotatably mounted on the inner wall of the No. 1 working box 1 , and a coil spring 25 is mounted on the outer wall of the second rotating shaft 24 .

[0039] The first gear 22 is configured as a sector gear; When the outer wall tooth block of the first gear 22 meshes with the second gear 23, the second gear 23 is driven to rotate. The rotation of the second gear 23 drives the rotation of the second rotating shaft 24. The rotation of the second rotating shaft 24 causes the coil spring 25 to deform and store elastic potential energy. When the outer wall tooth block of the first gear 22 is separated from the second gear 23, the coil spring 25 releases the elastic potential energy to reset, thereby causing the drain pipe 10 to swing back and forth, evenly distributing the dye liquid on the top of the filter screen 11; A rotation damper is installed on the outer wall of the second rotating shaft 24 to reduce the rotation speed when the coil spring 25 releases the elastic potential energy to reverse and reset the second rotating shaft 24, so that the liquid outlet pipe 9 swings back and forth at a slow speed.

[0040] Working principle and usage process: Before dyeing, first put the prepared dye solution into the No. 1 working box 1 and stir it through the mixing structure; Then the fiber / yarn-like material is mounted on the outer wall of several guide rollers 3, and one section of it is immersed in the dye solution, and finally the continuous dyeing is carried out by the rotation of the receiving roller; During dyeing, the water pump 4 is started by the PLC control. When the water pump 4 is started, the dye liquid in the No. 1 working box 1 is sucked away through the connection of the first connecting pipe 5, the second connecting pipe 6 and the liquid inlet pipe 7, and is connected through the third connecting pipe 8, the liquid outlet pipe 9 and the drain pipe 10. The dye liquid is discharged from the drain pipe 10 into the filter chamber 12 and filtered through the filter screen 11. When the dye enters the third connecting pipe 8 and flows, the water wheel blades 14 are driven to rotate. The rotation of the water wheel blades 14 drives the rotation of the first rotating shaft 15. When the first rotating shaft 15 rotates, it drives the reciprocating screw 17 to rotate through the pulley group 16. The rotation of the reciprocating screw 17 drives the movable plate 18 to move back and forth. The movement of the movable plate 18 drives the scraper 19 to slide back and forth on the top of the filter screen 11, pushing the impurities on the top of the filter screen 11 to the two sides of the filter screen 11 and into the slag collecting box 20 for collection. The dye in the impurities is filtered out into the filter chamber 12 through the through hole 21; When the reciprocating screw 17 rotates, it drives the first gear 22 to rotate. When the outer wall tooth block of the first gear 22 engages with the second gear 23, it drives the second gear 23 to rotate. The rotation of the second gear 23 drives the rotation of the second rotating shaft 24. The rotation of the second rotating shaft 24 drives the enclosed flow tube 10 to rotate. At the same time, the coil spring 25 deforms to store elastic potential energy. When the outer wall tooth block of the first gear 22 is separated from the second gear 23, the coil spring 25 releases the elastic potential energy to reset, thereby causing the drain pipe 10 to swing back and forth, evenly distributing the dye liquid on the top of the filter screen 11; The dye liquor filtered by the filter screen 11 is discharged from the liquid outlet 13 back into the No. 1 working box 1 for use, so as to achieve the effect of circulating filtration; After dyeing, the antenna is embedded in the fabric by sewing, heat pressing or bonding to avoid the influence of dyeing on the antenna.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
