Description

Technical Field

[0001] This utility model belongs to the technical field of mixing equipment, specifically relating to a raw material mixing device for a ceramic grinding wheel. Background Technology

[0002] In industrial production, materials need to be mixed evenly. Usually, a mixer is needed to mix various materials. In the current technology, the materials are mixed by a stirring shaft. However, when mixing small particles or powders, the stirring shaft will pass through the materials along its movement path without turning over the materials around the movement path. Therefore, the stirring shaft passes through small particles or powders but cannot fully turn over and mix all the materials. As a result, the mixing of small particles or powders is not sufficient.

[0003] Chinese utility model patent application number CN202520035471.X discloses a high-thickness grinding wheel mixing device, including a mixing box, a control panel fixedly installed on the front of the mixing box, a mounting frame fixedly installed on the top of the mixing box, a mounting plate provided at the bottom of the mounting frame, a limit slider provided on one side of the mounting plate, an adjustment frame fixedly installed at the bottom of the mounting plate, and a mixing mechanism provided on the adjustment frame. It continuously stirs and cuts the raw materials through the rotation of the stirring fork to achieve uniform mixing. However, since it only has a stirring fork, there is still a problem that the stirring fork passes through the material along its rotation trajectory during rotation, failing to ensure that all the material is fully turned over and mixed.

The second rotation drive mechanism has the same structure as the first rotation drive mechanism.

[0008] Preferably, the first rotation drive mechanism includes a motor, a synchronous pulley, a synchronous belt, and a reducer. One synchronous pulley is fixedly connected to the output end of the motor, and the other synchronous pulley is fixedly connected to the input end of the reducer. The synchronous belt is simultaneously wound around the outside of the two synchronous pulleys.

[0009] Preferably, a fixing frame is fixedly provided on the lower side of the upper cover, which is rotatably connected to the outside of the rotating shaft.

[0012] Preferably, the tilting unloading assembly includes a tilting drive assembly, a tilting shaft, and a tilting connecting arm. The tilting shaft is rotatably connected to the base and connected to the output end of the tilting drive assembly.

[0019] 3. The material cylinder is connected to the base through a tilting and unloading assembly. The tilting cylinder drives the material cylinder to tilt and unload the mixed material. At the same time, a guide plate is set on the side of the material cylinder near the unloading direction to unload the material, making the device more convenient to use.

[0020] 4. The top cover includes a fixed part and a flipping part. The flipping part is connected to the fixed part in a flip-up manner. When the material is being stirred, the flipping part can be flipped open to directly observe the mixing status of the material, or the material can be added at any time through the flipping part.

One end of the support arm is fixedly connected to the end of the rotating shaft, and the other end of the support arm is rotatably connected to the fixed frame. Under the action of the gravity of the pressure roller, the support arm can rotate around the fixed frame. The height of the pressure roller can be adjusted at any time according to the height of the material to ensure that the pressure roller presses on the material. Attached Figure Description

[0026] Figures 1-3 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-3 The present invention will be further described below.

[0027] like Figures 1-2 As shown, this utility model discloses a raw material mixing device for a ceramic grinding wheel, comprising a base 1, a material cylinder 19, an upper cover 10, and a mixing assembly. The material cylinder 19 is rotatably connected to the base 1 via a first rotation drive mechanism, and the material cylinder 19 itself also rotates. The upper cover 10 is movably connected to the base 1 and is flipped up above the material cylinder 19. The mixing assembly is mounted on the upper cover 10. When mixing materials, the upper cover 10 flips up and latches onto the upper side of the material cylinder 19. The mixing shaft 13 of the mixing assembly is located on the side of the upper cover 10 near the material cylinder 19. The mixing shaft 13 is rotatable, and its rotation direction is opposite to that of the material cylinder 19, enabling more thorough mixing. A pressure roller 16 is provided on one side of the mixing shaft 13, and the pressure roller 16 is rotatably connected to the lower side of the upper cover 10. The rotation axis of the pressure roller 16 is perpendicular to the rotation direction of the material cylinder 19. With the tangential direction set, when the material cylinder 19 rotates, the pressure roller 16 rolls and compacts the material. Then, in conjunction with the stirring component, the material is dispersed and mixed evenly. A fixing frame 14 is fixedly installed on the lower side of the upper cover 10, and a connecting shaft 34 is fixedly installed at the end of the fixing frame 14. The pressure roller 16 is rotatably connected to the outside of the rotating shaft 35. The connecting shaft 34 and the rotating shaft 35 are arranged parallel to each other.

One end of the support arm 15 is fixedly connected to the end of the rotating shaft 35, and the other end of the support arm 15 is rotatably connected to the connecting shaft 34, so that the support arm 15 can rotate around the connecting shaft 34. Under the action of gravity, the pressure roller 16 can rotate around the connecting shaft 34 at any time to adjust the height of the pressure roller 16. The height of the pressure roller 16 is adjusted at any time according to the height of the material to ensure that the pressure roller 16 presses on the material.

[0028] Both the top cover 10 and the mixing assembly are connected to the connecting plate 4. The connecting plate 4 drives the top cover 10 to close and open. Two upright plates 2 are fixedly installed on the base 1. The connecting plate 4 is rotatably connected to the upper end of the upright plates 2, and the top cover 10 is fixedly connected to the front end of the connecting plate 4. The top cover 10 is closed and opened by raising the front end of the connecting plate 4. Specifically, a top cover tilting cylinder 3 is provided on the lower side of the connecting plate 4. The lower end of the top cover tilting cylinder 3 is hinged to the base 1, and the upper end of the top cover tilting cylinder 3 is hinged to the connecting plate 4. When the output end of the top cover tilting cylinder 3 extends, it pushes the connecting plate 4 to rise, causing the connecting plate 4 to rotate around the connection point with the upright plates 2, thereby driving the lifting and lowering of the top cover 10 at the front end of the connecting plate 4, realizing the closing and opening of the top cover 10. During mixing, the top cover 10 is closed for mixing and blending. After mixing is completed, the top cover 10 is opened for easy unloading.

The output end of the second rotation drive mechanism passes through the connecting plate 4 and the upper cover 10 and is connected to the stirring frame 12. Multiple stirring shafts 13 are spaced apart on the stirring frame 12. The second rotation drive mechanism drives the stirring frame 12 to rotate, and the stirring shafts 13 stir the material in the material cylinder 19. The second rotation drive mechanism connected to the mixing frame 12 includes a mixing motor 6, a mixing synchronous pulley, a mixing synchronous belt 7, and a mixing reducer 9. The mixing motor 6 is fixedly mounted on the upper side of the connecting plate 4. A mixing drive wheel 5 is fixedly mounted on the output end of the mixing motor 6. A mixing driven wheel 8 is fixedly mounted on the input end of the mixing reducer 9. The mixing synchronous belt 7 is simultaneously wound around the outside of the mixing drive wheel 5 and the mixing driven wheel 8. The mixing frame 12 is connected to the output end of the mixing reducer 9. The mixing frame 12 is located at the center of the upper cover 10. A fixing frame 14 is provided on one side of the mixing frame 12. The fixing frame 14 is fixedly mounted on the upper cover 10. The two ends of the rotating shaft of the pressure roller 16 are fixedly connected to the fixing frame 14 through the support arm 15. The pressure roller 16 is rotatably connected to the rotating shaft. When the material cylinder 19 rotates, the pressure roller 16 rolls and presses on the material inside the material cylinder 19.

[0030] A fixing seat 17 is also installed on the lower side of the upper cover 10. A scraper 18 is fixedly installed on the fixing seat 17. When the upper cover 10 is fastened to the upper side of the material cylinder 19, the scraper 18 is located on the inner wall of the material cylinder 19. When the material cylinder 19 rotates, the scraper 18 scrapes off the material adhering to the inner wall of the material cylinder 19 and continues to mix it. In this embodiment, the upper cover 10 includes a fixing part and a flipping part 11. The stirring frame 12 and the pressure roller 16 are all located on the lower side of the fixing part. The flipping part 11 is rotatably connected to the fixing part. When the material is being stirred, the flipping part 11 can be flipped open to directly observe the mixing status of the material, or the material can be added at any time through the flipping part 11.

[0031] like Figure 3 As shown, the material cylinder 19 and its connected first rotation drive mechanism are mounted on the support plate 22. The material cylinder 19 is positioned above the support plate 22, and the first rotation drive mechanism is fixedly mounted on the lower side of the support plate 22. The output end of the first rotation drive mechanism passes through the support plate 22 and connects to the material cylinder 19. The first rotation drive mechanism connected to the material cylinder 19 includes a material cylinder motor 30, a material cylinder pulley 31, a material cylinder synchronous belt 32, and a material cylinder reducer 33. The material cylinder motor 30 is fixedly mounted on the lower side of the support plate 22, and the material cylinder 19 is positioned above the support plate 22. A material cylinder pulley 31 is fixedly installed at the output end of the material cylinder motor 30, and a material cylinder pulley 31 is fixedly installed at the input end of the material cylinder reducer 33. The material cylinder synchronous belt 32 is simultaneously wound around the outside of the two material cylinder pulleys 31. The material cylinder 19 is connected to the output end of the material cylinder reducer 33. The operation of the material cylinder motor 30 drives the material cylinder 19 to rotate. The rotation direction of the material cylinder 19 is opposite to the rotation direction of the stirring rack 12.

[0032] The support plate 22 is connected to the base 1 via a tilting and unloading assembly. After mixing, the material cylinder 19 is tilted and unloaded via the tilting and unloading assembly. The tilting and unloading assembly includes a tilting drive assembly, a tilting shaft 24, and a tilting connecting arm 23. Two columns 25 are fixedly installed on the base 1. The tilting shaft 24 is rotatably connected to the two columns 25 and is connected to the output end of the tilting drive assembly. The tilting drive assembly can drive the tilting shaft 24 to rotate. The support plate 22 is connected to the tilting shaft 24 via the tilting connecting arm 23. One end of the tilting connecting arm 23 is connected to... On the flipping shaft 24, the other end of the flipping connecting arm 23 is connected to the flipping mounting plate 29 on the support plate 22. The flipping shaft 24 rotates and pulls the support plate 22 to rotate around the flipping shaft 24, thereby realizing the tilting and dumping of the material cylinder 19. A guide plate 20 is fixedly provided on the side of the material cylinder 19 near the unloading direction. A guide plate mounting plate 28 is provided on the support plate 22. A fixing plate 21 is provided on one side of the guide plate 20.

One end of the connecting rod 27 is hinged to the output end of the material unloading flipping cylinder 26, and the other end of the connecting rod 27 is fixedly connected to the flipping shaft 24. The output end of the material unloading flipping cylinder 26 extends out, pushes the connecting rod 27 to make the flipping shaft 24 rotate, and then pulls the support plate 22 to realize the material unloading.

[0033] In use, the material to be mixed is added into the material cylinder 19. The output end of the top cover tilting cylinder 3 retracts and pulls the top cover 10 to fasten above the material cylinder 19. The stirring motor 6 rotates, causing the stirring frame 12 and each stirring shaft 13 to rotate and mix the material. At the same time, the material cylinder motor 30 also works, driving the material cylinder 19 to rotate. The rotation direction of the material cylinder 19 is opposite to the rotation direction of the stirring frame 12. When the material cylinder 19 rotates, the pressure roller 16 rolls and compacts the material. Then, in conjunction with the stirring shaft 13, the material is dispersed and mixed. The scraper 18 scrapes off the material adhering to the inner wall of the material cylinder 19 and mixes it together. This utility model achieves thorough mixing of small particles or powders through a simple structure, ensuring that small particles and powders can also be thoroughly mixed. After the material is mixed, the output shaft of the unloading tilting cylinder 26 extends and pushes the tilting shaft 24 to rotate. The tilting shaft 24 pulls the support plate 22 to discharge the material, which is then poured out from the top of the guide plate 20.
