Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0037] Embodiment 1:

[0038] Referring to Figures 1 - 5 , a dye grinding device for textile fabrics includes a grinding assembly, a water cooling assembly and a scraping and vibrating assembly;

[0039] The grinding assembly is used to grind and crush the dye. The grinding assembly includes a grinding box 1 and two grinding rollers 5 rotatably connected inside the grinding box 1;

[0040] One side of the grinding box 1 is fixedly connected with a first fixing box 8, and the other side of the grinding box 1 is fixedly connected with a second fixing box 23;

[0041] The water cooling assembly is used to cool the grinding rollers 5 to prevent damage to the dye. The water cooling assembly is composed of a liquid cooling unit and a piston unit. The liquid cooling unit includes two sealing rings 10 fixedly connected to both sides of the grinding rollers 5;

[0042] The scraping and vibrating assembly is used to scrape off the large particle dyes filtered down and intermittently vibrate and shed the adhered dyes. The scraping and vibrating assembly includes four electric telescopic rods 27 fixedly connected inside the grinding box 1;

[0043] One side of the grinding box 1 and inside the first fixing box 8 are rotatably connected with two first gears 6 respectively fixedly connected between the two grinding rollers 5. One side of the grinding box 1 close to the two first gears 6 is rotatably connected with a second gear 7. The outside of the first fixing box 8 is fixedly connected with a first motor 9, and the driving end of the first motor 9 is fixedly connected with the second gear 7;

[0044] In this embodiment, when the first motor 9 is started, the first motor 9 drives the second gear 7 to rotate at a high speed. The second gear 7 meshes with the two first gears 6, thereby driving the two first gears 6 to rotate synchronously, so that the two grinding rollers 5 rotate relatively. The dye to be ground is poured into the grinding box 1 from the feed port 4 at the top. The dye is uniformly and continuously extruded and ground between the two grinding rollers 5. Since the rotation speed of the grinding rollers 5 is stable, in the actual production scenario of large-scale textile printing and dyeing factories, hundreds of kilograms of dye can be processed per hour. Compared with traditional grinding equipment, the production cycle is greatly shortened, the production efficiency is improved, and significant economic benefits are brought to the enterprise.

[0045] Embodiment 2:

[0046] Referring to Figures 3 - 6, compared with the first embodiment, in this embodiment, water inlets 11 are rotatably connected inside two of the sealing rings 10, and water outlets 12 are rotatably connected inside the other two sealing rings 10. A liquid cooling pipe 13 is fixedly connected between the water inlets 11 and the water outlets 12, and the pipe wall of the liquid cooling pipe 13 is closely attached to the inner wall of the grinding roller 5.

[0047] The piston unit includes a first bevel gear 14 fixedly connected to one side of the second gear 7. Inside the first fixed box 8 and on one side of the grinding box 1, a first fixing plate 15 is fixedly connected. A first reciprocating lead screw 16 is rotatably connected to the first fixing plate 15. A second bevel gear 17 is fixedly connected to one side of the first reciprocating lead screw 16 close to the first bevel gear 14. A first lead screw nut 18 is threadedly sleeved on the first reciprocating lead screw 16. A push rod 19 is fixedly connected to the first lead screw nut 18. A first water tank 20 is fixedly connected inside the first fixed box 8. A piston 21 fixedly connected to the push rod 19 is arranged inside the first water tank 20. A water inlet pipe 22 is fixedly connected to one side of the first water tank 20. The water inlet pipe 22 is rotatably connected between the two water inlets 11 respectively. A second water tank 24 is fixedly arranged inside the second fixed box 23. The first water tank 20 and the second water tank 24 are connected and communicated through a return pipe 25. A water outlet pipe 26 is fixedly connected to one side of the second water tank 24. The water outlet pipe 26 is rotatably connected between the two water outlets 12 respectively.

[0048] In this embodiment, when the first motor 9 drives the second gear 7 to rotate, the first bevel gear 14 rotates synchronously. Through meshing with the second bevel gear 17, the power is transmitted to the first reciprocating lead screw 16. When the first reciprocating lead screw 16 rotates, the first lead screw nut 18 makes a reciprocating linear motion in the axial direction, driving the push rod 19 and the piston 21 to make a reciprocating motion inside the first water tank 20. When the piston 21 moves to the right, a negative pressure is formed inside the first water tank 20, and the coolant is sucked from the external water source through the water inlet pipe 22. When the piston 21 moves to the left, pressure is applied to the coolant inside the water tank, and the coolant is pressed into the water inlet 11 through the water inlet pipe 22. The coolant enters the liquid cooling pipe 13 through the water inlet 11, absorbs the heat generated by the high-speed operation of the grinding roller 5 when flowing through the inner wall of the grinding roller 5, then flows out through the water outlet 12, enters the second water tank 24 through the water outlet pipe 26, and then flows back to the first water tank 20 through the return pipe 25, realizing the automatic circulation of the coolant.

[0049] Furthermore, this design does not require additional power equipment such as a circulation pump, which not only reduces the equipment cost but also reduces energy consumption. At the same time, the stable coolant circulation can always control the temperature of the grinding roller 5 within an appropriate range, effectively preventing the chemical properties of the dye from changing due to high temperature, ensuring the quality characteristics such as the color and stability of the dye, and providing high-quality dye raw materials for the subsequent textile dyeing process.

[0050] Embodiment Three:

[0051] Reference Figures 7 - 14 Figures 7 - 14 , compared with the first embodiment and the second embodiment, in this embodiment, the tops of two adjacent electric telescopic rods 27 are fixedly connected with a first cross beam 28, and the tops of the other two adjacent electric telescopic rods 27 are fixedly connected with a second cross beam 29. A filter screen 30 is fixedly connected between the first cross beam 28 and the second cross beam 29. A second motor 31 is fixedly connected inside the first cross beam 28. The driving end of the first motor 31 is fixedly connected with a second reciprocating lead screw 32 that is rotatably connected to the first cross beam 28. A second lead screw nut 33 is threadedly sleeved on the second reciprocating lead screw 32. The top of the second lead screw nut 33 is fixedly connected with a cleaning scraper 34 through a support column that slides on the first cross beam 28.

[0052] Two fixing blocks 35 are fixedly connected to one side of the cleaning scraper 34. A fixing rod 36 is fixedly connected between the two fixing blocks 35. A striking plate 37 is rotatably connected between the two fixing blocks 35 and sleeved on the outer side of the fixing rod 36. A torsion spring 38 is fixedly connected between the inner wall of the striking plate 37 and the fixing rod 36. The inside of one fixing block 35 is rotatably connected through a one-way bearing 39 with a third gear 41 that is fixedly connected to the striking plate 37. A fourth gear 41 is rotatably connected to one side of the cleaning scraper 34 close to the third gear 39. A fifth gear 42 that is fixedly connected to the fourth gear 41 is rotatably connected to one side of the cleaning scraper 34 close to the second cross beam 29. A number of fixed toothed plates 43 are fixedly connected to the top of the second cross beam 29.

[0053] In this embodiment, the ground dye will pass through the filter screen 30 for filtration, and the large-particle dye will remain on the filter screen. In order to prevent the filter screen 30 from being blocked and ensure the smoothness of filtration, the scraping and vibrating assembly starts to work. The second motor 31 is started. The second motor 31 is fixed inside the first cross beam 28, and its driving end is fixedly connected with the second reciprocating lead screw 32. The second reciprocating lead screw 32 is rotatably connected inside the first cross beam 28. A second lead screw nut 33 is threadedly sleeved on the second reciprocating lead screw 32. The top of the second lead screw nut 33 is fixedly connected with a cleaning scraper 34 through a support column that slides on the first cross beam 28. When the second motor 31 drives the second reciprocating lead screw 32 to rotate, the second lead screw nut 33 will make a reciprocating linear motion on the second reciprocating lead screw 32, thereby driving the cleaning scraper 34 to make a reciprocating motion on the filter screen 30 and scraping the large-particle dye on the filter screen towards the storage boxes 44 on both sides of the grinding box 1.

[0054] Further, during the movement of the cleaning squeegee 34, the fifth gear 42 rotatably connected to the side of the cleaning squeegee 34 close to the second cross beam 29 will engage with a plurality of fixed toothed plates 43 fixedly connected to the top of the second cross beam 29. The fifth gear 42 is fixedly connected to the fourth gear 41, and the fourth gear 41 meshes with the third gear 40 rotatably connected inside a fixed block 35 through a one-way bearing 39. The third gear 40 is fixedly connected to the knocking plate 37. The knocking plate 37 is rotatably connected between two fixed blocks 35 and sleeved outside the fixed rod 36. A torsion spring 38 is fixedly connected between the inner wall of the knocking plate 37 and the fixed rod 36.

[0055] When the fifth gear 42 rotates in engagement with the fixed toothed plate 43, it will drive the fourth gear 41 and the third gear 40 to rotate, causing the knocking plate 37 to rotate against the elastic force of the torsion spring 38. When the fifth gear 42 disengages from the fixed toothed plate 43, the knocking plate 37 quickly rebounds under the action of the torsion spring 38 to slap and vibrate the filter net 30, shaking off the dyes adhering to the filter net. This combined scraping and vibrating impurity cleaning method can effectively prevent the filter net 30 from being blocked, ensure the smoothness of filtration, and improve the overall operating efficiency and stability of the device.

[0056] In addition, during the actual operation process, the staff only needs to regularly clean the storage box 44, which greatly simplifies the impurity treatment process, reduces the time and labor costs for equipment maintenance, maintains the long-term continuous and stable operation of the device, and effectively improves the automation degree and production efficiency of the entire production process.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes, should be covered by the protection scope of the present invention.
