Abstract
Description
Technical Field
[0001] This utility model belongs to the field of powder grinding technology, and specifically relates to a dye powder grinding machine. Background Technology
[0002] Clumping is a common problem with dyes during storage and transportation. The root cause lies in the inter-particle interactions within powdered dyes. When these interactions exceed the forces required to maintain dispersion, clumping occurs. Specifically, van der Waals forces and capillary forces between powder particles become very significant under certain conditions, while the forces of gravity and electrostatic repulsion that normally maintain particle dispersion weaken, making it impossible to keep the particles independently dispersed, thus leading to clumping.
[0003] The solution to the dye clumping problem should prioritize prevention, with treatment serving as a supplementary measure. In practice, we must pay particular attention to taking effective preventative measures to minimize dye clumping. However, if a small amount of dye inevitably clumps without affecting its performance or effectiveness, we can choose to grind and pulverize it to restore it to its original powdery state, ensuring continued usability. This method is simple and practical, significantly reducing waste and inconvenience caused by dye clumping.
[0004] Conventional grinding equipment typically uses a single-stage grinding head design without grading on the outer wall. A drawback of this design is that uneven material distribution can easily occur during the grinding process. This uneven distribution leads to some materials being over-ground while others fail to achieve the desired pulverization, resulting in significant differences in particle size after grinding. This not only reduces grinding efficiency but can also negatively impact dye performance.
[0005] In order to solve the problem of uneven material distribution during the material grinding process, this utility model aims to provide a powder grinding machine. Utility Model Content

The grinding head is divided into grinding section one, grinding section two and grinding section three from top to bottom. The distance between the outer wall of grinding section one and the inner wall of the grinding tank station is the largest.

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] A dye powder grinding mill includes a main unit 1 and a frame 2. The frame 2 is located at the top of the main unit 1, and a grinding head 3 is rotatably connected to the frame 2. A drive motor 4 is located at the top of the frame 2, and the top of the grinding head 3 is connected to the drive motor 4. The drive motor 4 drives the grinding head 3 to rotate and grind.
[0016] A grinding station 5 is located in the center of the main unit 1. The grinding station 5 has an inverted frustum shape, meaning its inner diameter gradually decreases from top to bottom, and the inclination angle of its inner wall is 50°. The grinding station 5 extends through the main unit 1, with its lower end opening at the bottom of the main unit 1. The dye powder ground by the grinding station 5 is discharged from the lower end opening of the grinding station 5. Several grinding teeth 14 are provided on the inner wall of the grinding station 5.
[0017] The grinding head 3 is conical, and its outer diameter gradually decreases from top to bottom. The grinding head 3 extends into the grinding tank station 5. The distance between the outer wall of the grinding head 3 and the inner wall of the grinding tank station 5 decreases sequentially from top to bottom. The grinding head 3 includes grinding section one 6, grinding section two 7, and grinding section three 8 connected sequentially from top to bottom. The inclination angle of the outer wall of grinding section two 7, grinding section one 6, and grinding section three 8 decreases sequentially. The inclination angle of the outer wall of grinding section one 6 is 60°, that of grinding section two 7 is 85°, and that of grinding section three 8 is 75°. Several grinding teeth 6 are provided on the outer walls of grinding sections one 6, two 7, and three 8.
[0018] A fourth grinding section 9, cylindrical in shape, is fixedly connected to the bottom of the third grinding section 8. A grinding seat 10 is located on the base of the main unit 1, with the fourth grinding section 9 positioned at its center. Both the outer and inner walls of the fourth grinding section 9 and the grinding seat 10 have rough grinding surfaces 11. A receiving hopper 12, inclined in design, is located at the bottom of the main unit 1 and is used to discharge powder. A guide cylinder 13 is located at the bottom of the grinding seat 10, guiding the powder into the receiving hopper 12 to prevent dust from being stirred up.
[0019] When using this device, the material is ground and pulverized in grinding section 6 and then reaches grinding section 7. Grinding section 7 connects grinding section 6 and grinding section 8, and also has its own grinding function. Grinding section 7 can trap larger material blocks and grind them. When the material blocks are ground to a specific particle size, they fall into grinding section 8. After two stages of screening and grinding in grinding sections 6 and 7, smaller and more uniform material blocks enter grinding section 8. The distance between the outer wall of grinding section 8 and the inner wall of the grinding tank station 5 gradually decreases from top to bottom, and the material blocks are further fined in grinding section 8. Finally, after being ground in grinding section 8, the material enters grinding section 9 for further grinding and is then discharged. The material passes through grinding sections 6, 7, 8, and 9 in sequence for screening and grinding. Only when the particle size of the material reaches a relatively uniform standard can it enter grinding section 9 for further grinding, thus ensuring more uniform grinding of the material.
