[0025] The present application embodiment discloses an automated grinding device. Figure 1-5 An automated grinding device comprises a casing 1, a grinding filter cartridge 2 is fixedly connected to the inner wall of the casing 1, a special-shaped turntable 3 is installed on the inner wall of the grinding filter cartridge 2, and striking blocks 4 are fixedly connected to multiple ends of the special-shaped turntable 3. A material guide plate 11 is symmetrically fixedly connected to the inner wall of the casing 1 below the special-shaped turntable 3. Two relatively rotating shafts 12 are installed on the inner wall of the casing 1 directly below the two material guide plates 11. A crushing roller 13 is fixedly connected to the outer walls of the two rotating shafts 12. One end of the two rotating shafts 12 passes through the casing 1 and is fixedly connected to a gear 14. The two gears 14 are meshed with each other. An actuator for driving the two crushing rollers 13 and the special-shaped turntable 3 to rotate is installed on the outer wall of the casing 1.

[0026] The actuator includes a driving wheel 15 rotatably connected to the outer wall of the casing 1 , and a driven wheel 16 rotatably connected to the outer wall of the casing 1 . A synchronous belt 17 is installed on the outer walls of the driving wheel 15 and the driven wheel 16 .

[0027] The outer wall of the casing 1 is fixedly mounted with a servo motor 5 via a fixing frame 6 , the output shaft of the servo motor 5 is fixedly connected to the driving wheel 15 , and its end penetrates the driving wheel 15 and the casing 1 and extends into the interior of the grinding filter cartridge 2 and is fixedly connected to the special-shaped turntable 3 .

[0028] One end of the rotating shaft 12 away from the gear 14 extends out of the housing 1 and is fixedly connected to the driven wheel 16 .

[0029] A feeding barrel 7 is fixedly connected to the outer wall of the casing 1 on one side away from the servo motor 5 . The feeding barrel 7 is communicated with the inner cavity of the special-shaped turntable 3 . A funnel 8 for feeding is arranged on the top outer wall of the feeding barrel 7 .

[0030] The inner wall of the feed barrel 7 is rotatably connected to a threaded conveying rod 9 , and a driving motor 10 is fixedly installed on the outer wall of one end of the feed barrel 7 away from the casing 1 , and the output shaft end of the driving motor 10 is fixedly connected to one end of the threaded conveying rod 9 .

[0031] A plurality of supporting legs 18 for supporting the casing 1 are fixedly connected to the outer walls of both sides of the casing 1 .

[0032] A discharge port 19 for discharging materials is fixedly connected to the bottom outer wall of the casing 1 , and the discharge port 19 is located directly below the two crushing rollers 13 .

[0033] The implementation principle of an automated grinding device in an embodiment of the present application is as follows: when in use, a large amount of material is added into the hopper 8 at one time, and then the driving motor 10 is started. The output shaft of the driving motor 10 drives the threaded conveying rod 9 to rotate, which can continuously and evenly convey the material inside the hopper 8. The material will be conveyed into the inner cavity of the special-shaped turntable 3 in the casing 1. At this time, the servo motor 5 is started by the actuator, and the output shaft of the servo motor 5 drives the driving wheel 15 to rotate, and then the driven wheel 16 is synchronously driven to rotate through the synchronous belt 17. When the driving wheel 15 rotates, the special-shaped turntable 3 is driven to rotate through the output end of the servo motor 5, and the special-shaped turntable 3 drives multiple striking blocks 4 to rotate at high speed, and when the driven wheel 16 rotates, it drives a rotating shaft 12 to rotate, and a rotating shaft When 12 rotates, the two gears 14 at the other end are meshed and transmitted, so that the two rotating shafts 12 rotate relatively. At this time, the rotating shaft 12 drives the two crushing rollers 13 to rotate relatively. When the material enters the inside of the casing 1, it will first drive multiple striking blocks 4 to strike and crush the larger particles of the tablet raw materials through the high-speed rotation of the special-shaped turntable 3, until the particles are smaller than the filter hole diameter of the grinding filter cylinder 2, and then fall on the two guide plates 11. The crushed materials are guided to the top of the two crushing rollers 13 through the two guide plates 11. At this time, the two crushing rollers 13 running relatively to each other perform secondary rolling and grinding on the materials, thereby realizing multi-stage grinding, ensuring the fine grinding of the materials and the uniformity of the particle size distribution. The materials after grinding are discharged through the discharge port 19.
