[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model.

[0021] The utility model provides a technical solution: As Figures 1 to 5As shown in the figure, in this embodiment, a granulating device for alumina ceramic powder used in a new energy switch includes a granulating box 1. A granulating mechanism is arranged inside the granulating box 1. The bottom of the granulating box 1 is fixedly connected to a screening box 2. A screening mechanism is arranged inside the screening box 2. The bottom of the screening box 2 is fixedly connected to a collection box 3. The screening mechanism is composed of a screening plate 9 and a mounting plate 10. The mounting plate 10 is an arc-shaped plate. An installation groove 13 adapted to the mounting plate 10 is formed on the side wall of the screening box 2. A limiting mechanism acting on the mounting plate 10 is arranged on the outer wall of the screening box 2. A handle 11 is fixedly connected to the outer ring side wall of the mounting plate 10. A screening plate 9 is arranged on the inner ring side wall of the mounting plate 10. The screening plate 9 is slidably connected to the mounting plate 10 through a sliding component. A vibration mechanism acting on the screening plate 9 is arranged at the bottom of the screening plate 9. The granulating mechanism is composed of a high-pressure roller 7, a forming plate 8 and a cutting blade 14. The forming plate 8 is fixedly connected to the inner wall of the granulating box 1. A plurality of forming holes are formed on the forming plate 8. The middle part of the upper end of the forming plate 8 is rotatably connected to a rotating column 6. A plurality of high-pressure rollers 7 are rotatably connected to the outer surface of the rotating column 6. The plurality of high-pressure rollers 7 are arranged in a circular array. The upper end of the rotating column 6 is connected to a first driving mechanism. The middle part of the lower end of the forming plate 8 is rotatably connected to a rotating shaft 16. A plurality of cutting blades 14 are fixedly connected to the outer surface of the rotating shaft 16. The plurality of cutting blades 14 are arranged in a circular array. The bottom of the rotating shaft 16 is connected to a second driving mechanism.

[0022] Among them, the first driving mechanism is composed of a fixing plate 4 and a first motor 5. The fixing plate 4 is fixedly connected to the top end of the granulating box 1. The middle part of the upper end of the fixing plate 4 is fixedly connected to a first motor 5. The output shaft of the first motor 5 penetrates through the fixing plate 4 and is fixedly connected to the upper end of the rotating column 6.

[0023] The first motor 5 drives the rotating column 6 to rotate, thereby driving the high-pressure roller 7 on the outer wall of the rotating column 6 to rotate.

[0024] Among them, the second driving mechanism is composed of a connecting column 15 and a third motor 17. The four side walls of the third motor 17 are respectively fixedly connected to the inner wall of the granulating box 1 through the connecting column 15. The output shaft of the third motor 17 is fixedly connected to the bottom of the rotating shaft 16.

[0025] The third motor 17 drives the rotating shaft 16 to rotate, thereby driving the cutting blade 14 on the rotating shaft 16 to rotate.

[0026] Among them, the sliding component is composed of a slider 22 and a spring 23. Three sliders 22 are fixedly connected to the side wall of the screening plate 9. The three sliders 22 are respectively slidably installed in three chutes 24 opened on the inner ring side wall of the mounting plate 10. A spring 23 is fixedly connected between the top wall of the inner cavity of the chute 24 and the upper end of the slider 22. The vibration mechanism is composed of a second motor 12 and a cam 21. The cam 21 is located below the screening plate 9. The cam 21 is rotatably connected to the inner wall of the screening box 2. A second motor 12 is fixedly connected to the outer wall of the screening box 2. The output shaft of the second motor 12 is fixedly connected to the cam 21.

[0027] During use, start the second motor 12 to drive the cam 21 to rotate. When the convex position of the cam 21 contacts the screening plate 9, the screening plate 9 will be pushed upward. The slider 22 fixedly connected to the screening plate 9 will compress the spring 23. When the convex position of the cam 21 moves away from the screening plate 9, under the action of the spring 23 restoring its deformation, the screening plate 9 will quickly reset. As the cam 21 continues to rotate, the screening plate 9 will continuously vibrate up and down.

[0028] Among them, the limiting mechanism is composed of a limiting plate 18, a movable sleeve 19 and a clamping plate 20. Two movable sleeves 19 are fixedly connected to the outer wall of the screening box 2. The two movable sleeves 19 are symmetrically distributed on both sides above the installation groove 13. A limiting plate 18 is slidably inserted into the movable sleeve 19. A clamping plate 20 is fixedly connected to the upper side of the front end of the limiting plate 18.

[0029] After the mounting plate 10 is installed in the installation groove 13, move the limiting plate 18 downward so that the limiting plate 18 abuts against the outer wall of the mounting plate 10. Since the mounting plate 10 is an arc-shaped plate, the two limiting plates 18 can prevent the mounting plate 10 from moving to both sides and directly in front of the granulating box 1, and the inner wall of the installation groove 13 can prevent the mounting plate 10 from moving up and down and inside the granulating box 1, thereby completing the fixation of the mounting plate 10.

[0030] The utility model provides a granulating device for alumina ceramic powder used in a new energy switch, and the specific working principle is as follows:

[0031] During use, put the alumina ceramic raw material into the granulating box 1, start the first motor 5 to drive the rotating column 6 to rotate, thereby driving the high-pressure roller 7 on the outer wall of the rotating column 6 to rotate. The high-pressure roller 7 will extrude the alumina ceramic raw material into the forming holes on the forming plate 8, so that the alumina ceramic raw material extends out from the other side of the forming holes in a strip shape. At the same time, start the third motor 17 to drive the rotating shaft 16 to rotate, thereby driving the cutting blade 14 on the rotating shaft 16 to rotate. The cutting blade 14 will cut the extended strip-shaped alumina ceramic raw material, thereby cutting it into granular form. Then start the second motor 12 to drive the cam 21 to rotate. When the convex position of the cam 21 contacts the screening plate 9, it will push the screening plate 9 upward. The slider 22 fixedly connected to the screening plate 9 will compress the spring 23. When the convex position of the cam 21 moves away from the screening plate 9, under the action of the spring 23 restoring deformation, the screening plate 9 will quickly reset. As the cam 21 continues to rotate, the screening plate 9 will continuously vibrate up and down, thereby screening the formed particles. The particles with qualified sizes will fall into the collection box 3 for collection, and the unqualified particles will remain on the screening plate 9. Pull out the mounting plate 10 and the screening plate 9 to clean the unqualified particles.
