Abstract
Description
Technical Field
[0001] This invention relates to the field of grinding equipment technology, and in particular to a pigment grinding device for controlling the particle size of the finished product. Background Technology
[0002] Iron oxide pigments are pigments with good dispersibility, excellent lightfastness, and weather resistance. Iron oxide pigments mainly refer to four categories of coloring pigments based on iron oxides: iron oxide red, iron oxide yellow, iron oxide black, and iron oxide brown. Iron oxide red is the most prevalent (accounting for approximately 50% of iron oxide pigments). Mica iron oxide, used as an anti-rust pigment, and magnetic iron oxide, used as a magnetic recording material, also fall under the category of iron oxide pigments. Iron oxide is the second largest inorganic pigment after titanium dioxide, and the largest colored inorganic pigment overall, thus it is widely used in building materials, coatings, plastics, electronics, tobacco, pharmaceuticals, rubber, ceramics, inks, magnetic materials, papermaking, and other fields.
[0003] Currently, grinding is required in the production of iron oxide pigments. However, the grinding gap and grinding pressure cannot be adjusted during the grinding process, which makes it impossible to accurately control the particle size of the finished product when raw materials of different sizes and hardness are ground, thus affecting the final grinding quality. To address this issue, we provide a pigment grinding device that controls the particle size of the finished product. Summary of the Invention

[0017] The beneficial effects of this invention are: 1. By setting up a feeding drum and feeding baffle, chemical raw materials are added inside the feeding box. The chemical raw materials fall into the feeding drum through the feeding pipe. At this time, the drive motor is started. The drive motor rotates and drives the drive rod to rotate. The rotating drive rod drives the feeding drum to rotate. The rotation of the feeding drum drives the grinding roller to rotate. The rotation of the grinding roller can grind the chemical raw materials. The rotation of the feeding drum can make the chemical raw materials falling into the feeding drum evenly fall between the grinding roller and the grinding fixed roller through the feeding through hole. This can avoid raw material accumulation or local overload, ensure grinding uniformity, and realize continuous production, thereby improving efficiency.
[0018] 2. Through the set adjustment mechanism, the rotating feed drum drives the spur gear ring to rotate. The rotating spur gear ring drives the spur gear to rotate through meshing. The rotation of the spur gear drives the transmission rod to rotate inside the connecting plate. The rotation of the transmission rod drives the transmission turntable to rotate. The rotating transmission turntable drives the adjustment arc block to rotate. The rotation of the adjustment arc block drives the connecting rod to move linearly through the limiting effect of the set arc surface and the sliding box. The linear movement of the connecting rod drives the connecting plate to move linearly. The linear movement of the connecting plate can push the flipping arc plate to rotate around the flipping rod. Through the adjustment mechanism (such as spur gear ring, transmission turntable, etc.), the grinding gap or pressure can be dynamically adjusted to adapt to raw materials of different hardness and accurately control the particle size of the finished product. Then, when the connecting rod disengages from the adjustment arc block, the grinding diameter is increased so that the ground chemical raw materials can fall into the collection box through the feed trough for collection.
[0019] 3. Through the set gap filling mechanism, the flipping arc plate flipping motion drives the isolation soft plate to flip through the torque. The flipping isolation soft plate can seal the gap between the two flipping arc plates during the fine grinding process. The flipping arc plate and the isolation soft plate swing periodically under the action of the torsion spring, automatically cleaning up residual materials and reducing the frequency of downtime maintenance.
[0020] 4. Through the auxiliary mechanism, the rotating arc plate drives the arc-shaped toothed plate to rotate. The rotating arc-shaped toothed plate drives the transmission gear to rotate through meshing. The rotating transmission gear drives the connecting rack to move linearly inside the auxiliary mounting plate through meshing. The linear motion of the connecting rack drives the auxiliary rack to move linearly. The linear motion of the auxiliary rack drives the auxiliary gear to rotate through meshing. The rotation of the auxiliary gear drives the filling rod to rotate. The rotation of the filling rod drives the hinge to retract. The retraction of the hinge can lift the isolation soft plate, automatically compensating for the loosening or deformation of the soft plate caused by long-term friction or material impact, maintaining the airtightness of the grinding chamber and preventing powder leakage. At the same time, in the fine grinding stage (when the rotating arc plate flips inward), the lifted isolation soft plate forms a closed space, forcing the material to stay in the high-pressure grinding zone, preventing fine particles from being thrown out before they meet the standards, and ensuring sufficient grinding.

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0040] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.
[0041] In existing grinding devices, the raw materials fall in a piled-up state during the pigment grinding process. This results in a large amount of pigment material being ground in one position, requiring several rotations of the grinding rollers to evenly distribute it between the two grinding rollers, thus reducing the grinding efficiency of the pigment. Based on this problem, the following improvements are proposed: Reference Figures 1-15This invention provides a pigment grinding device for controlling the particle size of the finished product. The device includes a base 1, a feeding box 2 fixedly connected to the top of the base 1, a feeding trough 3 inside the feeding box 2, a collection box 4 fixedly connected to one side of the feeding box 2, a support column 5 fixedly connected to the top of the feeding box 2, a feeding box 6 fixedly connected to the top of the support column 5, a feeding pipe 7 fixedly connected to one side of the feeding box 6, a mounting frame 8 fixedly connected to the top of the collection box 4 near the support column 5, a feeding mechanism at the bottom of the mounting frame 8, and a connecting plate 9 fixedly connected to the inner side of the mounting frame 8. The bottom of the connecting plate 9 is provided with an adjustment mechanism and an auxiliary mechanism. The feeding mechanism includes a drive motor 10 fixedly connected to the top of the mounting frame 8 by a bolt assembly. The output end of the drive motor 10 is fixedly connected to a drive rod 11. The bottom end of the drive rod 11 is fixedly connected to a feeding drum 12. The inner side of the connecting plate 9 is fixedly connected to a grinding fixed roller 38. The bottom of the feeding drum 12 is fixedly connected to a grinding roller 37. The inner bottom wall of the feeding drum 12 is fixedly connected to a feeding baffle 13. The inner bottom wall of the feeding drum 12 near the feeding baffle 13 is provided with a feeding through hole. Chemical raw materials are added inside the feeding box 6. The chemical raw materials can fall into the unloading drum 12 through the feeding pipe 7. At this time, the drive motor 10 is started. The drive motor 10 rotates and drives the drive rod 11 to rotate. The rotating drive rod 11 drives the unloading drum 12 to rotate. The rotation of the unloading drum 12 drives the grinding roller 37 to rotate. The rotation of the grinding roller 37 can grind the chemical raw materials. The rotation of the unloading drum 12 can make the chemical raw materials falling into the unloading drum 12 evenly fall between the grinding roller 37 and the grinding fixed roller 38 through the unloading through hole. This can avoid the accumulation of raw materials or local overload, ensure the uniformity of grinding, and realize continuous production and improve efficiency.
[0042] During the implementation of the above solution, it was found that the grinding gap and grinding pressure could not be adjusted during the pigment grinding process. This resulted in the inability to accurately control the particle size of the finished product when grinding raw materials of different sizes and hardness, affecting the final grinding quality. Therefore, the following technical improvements were made: Reference Figures 4-6The adjustment mechanism includes a spur gear ring 14 fixedly connected to the outer wall of the feeding drum 12, and four spur gears 15 meshing with the outer wall of the spur gear ring 14 respectively. A transmission rod 16 is fixedly connected to the bottom of the spur gear 15. The bottom end of the transmission rod 16 extends through to the bottom of the connecting plate 9 and is fixedly connected to a transmission turntable 17. The transmission rod 16 is rotatably connected to the connecting plate 9. Four adjusting arc blocks 18 are fixedly connected to the outer wall of the transmission turntable 17. The adjustment mechanism also includes a fixed flipping block 23 fixedly connected to the bottom of the grinding fixed roller 38, and a flipping rod 24 extends through the inner side of the fixed flipping block 23 and is rotatably connected to the flipping rod 24. Next, both ends of the flipping rod 24 pass through the inner side of the flipping arc plate 22 and are fixedly connected to the flipping arc plate 22. A torsion spring 39 is provided on the outer wall of the flipping rod 24 between the fixed flipping block 23 and the flipping arc plate 22. An isolation soft plate 29 is installed between every two flipping arc plates 22. A connecting component is provided between the flipping arc plate 22 and the transmission turntable 17. A gap-filling component is provided between every two flipping arc plates 22. The connecting component includes a sliding box 21 fixedly connected to the top of the collection box 4. A connecting abutment plate 20 is slidably connected inside the sliding box 21. A connecting abutment rod 19 is fixedly connected to the outside of the connecting abutment plate 20. The rotating feed drum 12 drives the spur gear ring 14 to rotate. The rotating spur gear ring 14 drives the spur gear 15 to rotate through meshing. The rotation of the spur gear 15 drives the transmission rod 16 to rotate inside the connecting plate 9. The rotation of the transmission rod 16 drives the transmission turntable 17 to rotate. The rotating transmission turntable 17 drives the adjusting arc block 18 to rotate. The rotation of the adjusting arc block 18 drives the connecting rod 19 to move linearly through the limiting effect of the set arc surface and the sliding box 21. The linear movement of the connecting rod 19 drives the connecting plate 20 to move linearly. The linear movement of the connecting plate 20 can push the flipping arc plate 22 to rotate around the flipping rod 24. The grinding gap or pressure can be dynamically adjusted by the adjusting mechanism (such as the spur gear ring 14, the transmission turntable 17, etc.) to adapt to raw materials of different hardness and accurately control the particle size of the finished product. Then, when the connecting rod 19 is disengaged from the adjusting arc block 18, the grinding diameter is increased so that the ground chemical raw materials can fall into the collection box 4 through the feed trough 3 for collection.
[0043] During the implementation of the above solution, it was found that the turning gap between the two turning arc plates 22 during the pigment grinding process causes incompletely ground pigment raw materials to be trapped in the gap, affecting the normal operation of the machine. Therefore, the following technical improvements were made: Reference Figures 4-6 The missing component includes a sliding groove 25 disposed on one side of the flip arc plate 22, and a sliding plate 26 is slidably connected to the inner wall of the sliding groove 25. A missing rotating rod 27 passes through the top of one side of the sliding plate 26 and is rotatably connected to the missing rotating rod 27. Both ends of the missing rotating rod 27 pass through the hinge 28 and are rotatably connected to the hinge 28. An isolation soft plate 29 is fixedly connected between the two flip arc plates 22. The flipping arc plate 22 flips by torque, which drives the isolation soft plate 29 to flip. The flipping isolation soft plate 29 can seal the gap between the two flipping arc plates 22 during the fine grinding process. The flipping arc plate 22 and the isolation soft plate 29 swing periodically under the action of the torsion spring 39, automatically cleaning up residual materials and reducing the frequency of downtime maintenance.
[0044] During the implementation of the above solution, it was found that during the pigment grinding process, because the isolation plate 29 is made of flexible material, the pigment raw material being ground may break through the isolation plate 29 due to grinding pressure before it is completely ground, resulting in leakage and affecting the pigment processing accuracy. Therefore, the following technical improvements were made: Reference Figures 7-12 The auxiliary mechanism includes an auxiliary mounting plate 35 fixedly connected to the bottom of the flipping arc plate 22, and a connecting rack 33 slidably connected inside the auxiliary mounting plate 35. An auxiliary rack 34 is fixedly connected to one end of the connecting rack 33. The auxiliary mechanism also includes two auxiliary fixing plates 32 fixedly connected to the top of the auxiliary mounting plate 35, and a transmission gear 31 is rotatably connected between the two auxiliary fixing plates 32. The transmission gear 31 meshes with the connecting rack 33. A transmission gear 31 meshes with the transmission gear 31 and is fixedly connected to the inner side of the feeding box 2. The auxiliary mechanism also includes an auxiliary gear 36 fixedly connected to the bottom of one of the filling rotating rods 27. An auxiliary rack 34 is fixedly connected to one end of the connecting rack 33, and the auxiliary gear 36 meshes with the auxiliary rack 34. The rotating arc plate 22 drives the arc toothed plate 30 to rotate. The rotating arc toothed plate 30 drives the transmission gear 31 to rotate through meshing. The rotating transmission gear 31 drives the connecting rack 33 to move linearly inside the auxiliary mounting plate 35 through meshing. The linear movement of the connecting rack 33 drives the auxiliary rack 34 to move linearly. The linear movement of the auxiliary rack 34 drives the auxiliary gear 36 to rotate through meshing. The rotation of the auxiliary gear 36 drives the filling rod 27 to rotate. The rotation of the filling rod 27 drives the hinge 28 to retract. The retraction of the hinge 28 can lift the isolation soft plate 29, automatically compensating for the loosening or deformation of the soft plate caused by long-term friction or material impact, maintaining the airtightness of the grinding chamber and preventing powder leakage. At the same time, in the fine grinding stage (when the rotating arc plate flips inward), the lifted isolation soft plate 29 forms a closed space, forcing the material to stay in the high-pressure grinding zone, preventing fine particles from being thrown out before reaching the standard, and ensuring sufficient grinding.
[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
