Technical Field

[0001] This invention relates to the field of textile fabric technology, and in particular to a dye grinding device for textile fabrics. Background Technology

[0002] Dyes are a class of organic compounds that can give other substances bright and fast colors. Since the pigments used now are all artificially synthesized, they are also called synthetic dyes. Dyes are mostly used for dyeing textile fabrics, and grinding equipment is needed to grind the dyes during the dyeing process.

A filter screen is fixedly connected between the first and second crossbeams. A second motor is fixedly connected inside the first crossbeam. A second reciprocating screw, rotatably connected to the first crossbeam, is fixedly connected to the drive end of the first motor. A second screw nut is threaded onto the second reciprocating screw. A cleaning scraper is fixedly connected to the top of the second screw nut via a support column sliding on the first crossbeam. A cleaning scraper is fixedly connected to one side of the cleaning scraper. Two fixed blocks are fixedly connected to a fixed rod. A striking plate is rotatably connected between the two fixed blocks and sleeved on the outside of the fixed rod.

[0017] The present invention has the following beneficial effects:

[0018] 1. By setting up a grinding assembly, the first motor drives the second gear, which in turn drives the two first gears connected to the grinding rollers, realizing the relative rotation of the two grinding rollers. This enables efficient grinding and pulverization of dyes. This gear transmission structure is stable and has high power transmission efficiency, ensuring the continuity and efficiency of the grinding process and greatly improving production efficiency.

[0019] 2. By setting up a liquid cooling component, the liquid cooling pipe is closely attached to the inner wall of the grinding roller. The circulation of coolant is achieved by using the inlet and outlet in conjunction with the sealing ring. This effectively cools the grinding roller, preventing damage to the dye caused by the high temperature generated during grinding and ensuring the quality of the dye. The piston unit, through components such as the first bevel gear and the first reciprocating screw, converts part of the power of the first motor into the reciprocating motion of the piston in the first water tank, realizing the automatic circulation of coolant. No additional power equipment is required, which is energy-saving, environmentally friendly, and ensures the stable operation of the water cooling system.

[0020] 3. By setting up a scraping and vibration assembly, the coordinated operation of components such as the electric telescopic rod, crossbeam, reciprocating screw, cleaning scraper, and striking plate effectively cleans large particles of dye that have been filtered out. During the movement of the cleaning scraper, the meshing of the fifth gear with the fixed toothed plate drives the fourth and third gears to rotate, causing the striking plate to intermittently vibrate the filter screen under the action of the torsion spring, shaking off the dye adhering to the filter screen. This cleaning method that combines scraping and vibration can effectively prevent the filter screen from clogging, ensure the smoothness of filtration, and improve the overall operating efficiency and stability of the device.

Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Example 1:

[0038] Reference Figures 1-5 A dye grinding device for textile fabrics includes a grinding component, a water cooling component, and a scraping and vibration component.

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

[0040] A first fixing box 8 is fixedly connected to one side of the grinding box 1, and a second fixing box 23 is fixedly connected to the other side of the grinding box 1.

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

[0042] The scraping and vibration assembly is used to scrape off large particles of dye that have been filtered out and to intermittently shake off the adhering dye. The scraping and vibration assembly includes four electric telescopic rods 27 that are fixedly connected inside the grinding box 1.

[0043] Two first gears 6 are rotatably connected to one side of the grinding box 1 and inside the first fixed box 8, respectively fixed to the two grinding rollers 5. A second gear 7 is rotatably connected to the side of the grinding box 1 near the two first gears 6. A first motor 9 is fixedly connected to the outside of the first fixed box 8. The drive end of the first motor 9 is fixedly connected to the second gear 7.

[0044] In this embodiment, the first motor 9 is started, driving the second gear 7 to rotate at high speed. The second gear 7 meshes with the two first gears 6, thereby driving the two first gears 6 to rotate synchronously, causing the two grinding rollers 5 to rotate relative to each other. The dye to be ground is poured into the feed port 4 at the top of the grinding box 1. The dye is subjected to uniform and continuous compression and grinding between the two grinding rollers 5. Because the rotation speed of the grinding rollers 5 is stable, in the actual production scenario of a large-scale textile printing and dyeing plant, 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] Example 2:

[0046] Reference Figures 3-6Compared to Embodiment 1, in this embodiment, two of the sealing rings 10 are rotatably connected to water inlets 11, and the other two sealing rings 10 are rotatably connected to water outlets 12. A liquid cooling pipe 13 is fixedly connected between the water inlets 11 and the water outlets 12, and the wall of the liquid cooling pipe 13 is in close contact with 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. A first fixed plate 15 is fixedly connected inside the first fixed box 8 and to one side of the grinding box 1. A first reciprocating screw 16 is rotatably connected to the first fixed plate 15. A second bevel gear 17 is fixedly connected to the side of the first reciprocating screw 16 closest to the first bevel gear 14. A first screw nut 18 is threaded onto the first reciprocating screw 16. A push rod 19 is fixedly connected to the first screw nut 18. The interior of the first fixed box 8 is fixed... A first water tank 20 is connected, and a piston 21 fixedly connected to a push rod 19 is installed inside the first water tank 20. A water inlet pipe 22 is fixedly connected to one side of the first water tank 20, and the water inlet pipe 22 is rotatably connected to two water inlets 11 respectively. A second water tank 24 is fixedly installed inside the second fixed box 23. The first water tank 20 and the second water tank 24 are connected through a return pipe 25. A water outlet pipe 26 is fixedly connected to one side of the second water tank 24, and the water outlet pipe 26 is rotatably connected to 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, it transmits power to the first reciprocating screw 16. When the first reciprocating screw 16 rotates, the first screw nut 18 performs reciprocating linear motion in the axial direction, driving the push rod 19 and piston 21 to perform reciprocating motion in the first water tank 20. When the piston 21 moves to the right, a negative pressure is formed in the first water tank 20, and coolant is drawn from the external water source through the water inlet pipe 22. When the piston 21 moves to the left, it applies pressure to the coolant in the water tank, forcing the coolant 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 it flows through the inner wall of the grinding roller 5, and 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 coolant.

[0049] Furthermore, this design eliminates the need for additional power equipment such as circulation pumps, reducing both equipment costs and energy consumption. At the same time, the stable circulation of coolant keeps the temperature of the grinding roller 5 within a suitable range, effectively preventing changes in the chemical properties of the dye due to high temperatures. This ensures the quality characteristics of the dye, such as color and stability, providing high-quality dye raw materials for subsequent textile dyeing processes.

[0050] Example 3:

[0051] Reference Figures 7-14 Compared to Embodiment 1 and Embodiment 2, in this embodiment, the tops of two adjacent electric telescopic rods 27 are fixedly connected to a first crossbeam 28, and the tops of the other two adjacent electric telescopic rods 27 are fixedly connected to a second crossbeam 29. A filter screen 30 is fixedly connected between the first crossbeam 28 and the second crossbeam 29. A second motor 31 is fixedly connected inside the first crossbeam 28. The drive end of the first motor 31 is fixedly connected to a second reciprocating screw 32 that is rotatably connected to the first crossbeam 28. A second screw nut 33 is threaded on the second reciprocating screw 32. A cleaning scraper 34 is fixedly connected to the top of the second screw nut 33 through a support column that slides on the first crossbeam 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 outside 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. A third gear 41, which is fixedly connected to the striking plate 37, is rotatably connected inside one of the fixing blocks 35 through a one-way bearing 39. A fourth gear 41 is rotatably connected inside the cleaning scraper 34 on the side near the third gear 39. A fifth gear 42, which is fixedly connected to the fourth gear 41, is rotatably connected on the side of the cleaning scraper 34 near the second crossbeam 29. Several fixing toothed plates 43 are fixedly connected to the top of the second crossbeam 29.

[0053] In this embodiment, the ground dye is filtered through the filter screen 30. Large dye particles remain on the filter screen. To prevent the filter screen 30 from clogging and ensure smooth filtration, the scraping and vibration assembly starts working, activating the second motor 31. The second motor 31 is fixed inside the first crossbeam 28, and its drive end is fixedly connected to the second reciprocating screw 32. The second reciprocating screw 32 is rotatably connected inside the first crossbeam 28. A second screw nut 33 is threaded onto the second reciprocating screw 32. The top of the second screw nut 33 is fixedly connected to a cleaning scraper 34 via a support column that slides on the first crossbeam 28. When the second motor 31 drives the second reciprocating screw 32 to rotate, the second screw nut 33 will reciprocate linearly on the second reciprocating screw 32, thereby driving the cleaning scraper 34 to reciprocate on the filter screen 30, scraping the large dye particles on the filter screen towards the storage boxes 44 on both sides of the grinding box 1.

[0054] Furthermore, during the movement of the cleaning scraper 34, the fifth gear 42, which is rotatably connected to the side of the cleaning scraper 34 near the second crossbeam 29, will mesh with several fixed toothed plates 43 fixedly connected to the top of the second crossbeam 29. The fifth gear 42 is fixedly connected to the fourth gear 41. The fourth gear 41 meshes with the third gear 40, which is rotatably connected to a fixed block 35 through a one-way bearing 39. The third gear 40 is fixedly connected to the striking plate 37. The striking plate 37 is rotatably connected between the two fixed blocks 35 and sleeved on the outside of the fixed rod 36. A torsion spring 38 is fixedly connected between the inner wall of the striking plate 37 and the fixed rod 36.

[0055] When the fifth gear 42 meshes with the fixed toothed plate 43 and rotates, it drives the fourth gear 41 and the third gear 40 to rotate, causing the striking 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 striking plate 37 rebounds rapidly under the action of the torsion spring 38, vibrating the filter screen 30 to shake off the dye adhering to the filter screen. This cleaning method of scraping and vibration can effectively prevent the filter screen 30 from clogging, ensure the smoothness of filtration, and improve the overall operating efficiency and stability of the device.

[0056] In addition, during actual operation, staff only need to clean the storage box 44 periodically, which greatly simplifies the impurity handling process, reduces equipment maintenance time and labor costs, maintains the continuous and stable operation of the device for a long time, and effectively improves the automation level and production efficiency of the entire production process.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
