Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: Reference Figure 1-4The illustrated pharmaceutical grinding equipment includes a fixed frame 1, which supports and protects the internal structure, providing a stable mounting foundation for the entire equipment. A hot air blower 4 is installed on the outside of the fixed frame 1. The hot air blower 4 generates hot air to preheat the pharmaceuticals, ensuring they reach a suitable temperature before grinding, thus improving grinding efficiency and pharmaceutical quality. The output end of the hot air blower 4 is fixedly connected to an air inlet pipe 3. The air inlet pipe 3 is used to deliver the hot air generated by the hot air blower 4 into the fixed frame 1, ensuring that the hot air can accurately act on the medicine. One end of the air inlet pipe 3 passes through the fixed frame 1 to realize the input path of the hot air. A deflector rod 20 is rotatably connected to the inner wall of the fixed frame 1. The deflector rod 20 rotates inside the fixed frame 1, and its function is to drive the stirring rod 21 to move, thereby stirring the medicine. One end of the deflector rod 20 passes through the fixed frame 1, which is convenient for connecting to an external power source. Multiple stirring rods 21 are fixedly connected to the outer side of the deflector rod 20. The stirring rods 21 rotate with the deflector rod 20, which can fully stir the medicine, make the medicine evenly heated, and at the same time help the medicine to disperse better during the grinding process, which is beneficial to the grinding operation. One end of the deflector rod 20 is connected to an external servo motor as a power source. The servo motor can precisely control the speed and rotation angle of the deflector rod 20, ensuring the stability and adjustability of the stirring effect. A pair of arc-shaped plates 18 are fixedly connected to the inner wall of the fixed frame 1. The arc-shaped plates 18 guide and constrain the medicine, allowing it to be stirred and subsequently conveyed within a fixed area. One of the arc-shaped plates 18 has a slot 19 on its outer side, providing space for the sliding of a baffle 15. This slot, in conjunction with the conveying assembly, facilitates the conveying of the medicine. A conveying assembly is positioned between the pair of arc-shaped plates 18. The conveying assembly includes a baffle 15 positioned between the pair of arc-shaped plates 18. The baffle 15 is slidably connected to the slot 19 and can move within the slot 19. This movement controls the amount of medicine conveyed. A sliding plate 13 is fixedly connected to one end of the baffle 15, transmitting the movement of the baffle 15 and ensuring accurate movement under external power. A groove 10, adapted to the sliding plate 13, is provided on the outer side of the fixed frame 1. This groove provides a track for the movement of the sliding plate 13, ensuring its stability and accuracy. A gear 14 is fixedly connected to the outer side of the sliding plate 13. The gear 14 meshes with an external gear to transmit power and drive the sliding plate 13 to move. A motor 11 is fixedly connected to the outer side of the fixed frame 1. The motor 11 serves as a power source, providing power to the conveying assembly and driving the gear 12 to rotate. The output end of the motor 11 is fixedly connected to the gear 12, which meshes with the gear 14. Through gear transmission, the rotational motion of the motor 11 is converted into the linear motion of the sliding plate 13, which in turn drives the baffle 15 to move, thus realizing the conveying of medicine.

[0023] Example 2: Reference Figure 1-4Based on the same concept as Embodiment 1 above, this embodiment further proposes that the fixed frame 1 serves to support and fix other components, ensuring the structural stability of the entire grinding device. A pair of first grinding rollers 16 rotatably connected to its inner side are used for the initial grinding of the raw material entering from the feed pipe 2, initially crushing larger particles. One end of each pair of first grinding rollers 16 is fixedly connected to a transmission rod 5, which passes through the fixed frame 1 and transmits power to drive the first grinding rollers 16 to rotate. A pair of second grinding rollers 17 rotatably connected to the inner side of the fixed frame 1 perform secondary grinding of the raw material after the initial grinding by the first grinding rollers 16, further refining the raw material to achieve a finer particle size and reducing material jamming. One end of each pair of second grinding rollers 17 is fixedly connected to a rotating rod 7, which passes through the fixed frame 1 and also transmits power to drive the second grinding rollers 17 to rotate. The spacing between the first grinding rollers 16 is greater than the spacing between the second grinding rollers 17. This design allows the raw material to undergo preliminary coarse grinding first through the first grinding rollers 16 with a larger spacing, and then fine grinding through the second grinding rollers 17 with a smaller spacing, meeting the processing requirements of progressively refining the raw material. A pair of motors 6 are fixedly connected to the outside of the fixed frame 1, serving as a power source. Their output ends are fixedly connected to a pair of transmission rods 5, providing power for the rotation of the first grinding roller 16. The transmission rods 5 and the rotating rod 7 located directly below are connected by the same transmission track 8. The power transmitted from the motors 6 to the transmission rods 5 is synchronously transmitted to the rotating rod 7 through the transmission track 8, thereby driving the second grinding rollers 17 to rotate, ensuring that the first grinding rollers 16 and the second grinding rollers 17 can work together. The feed pipe 2 is fixedly connected to the top of the fixed frame 1, used to guide the raw material into the fixed frame 1, so that the raw material can smoothly reach the first grinding roller 16 for grinding. The bottom frame 9 is fixedly connected to the bottom of the fixed frame 1, serving to receive the ground raw material and guide the raw material out of the equipment for easy subsequent collection.

[0024] The working principle of this utility model is as follows: Raw materials are introduced into the fixed frame 1 through the feed pipe 2. The externally installed servo motor drives the deflection rod 20 and the stirring rod 21 to rotate. The hot air blower 4 is controlled to introduce hot air into the fixed frame 1 through the air inlet pipe 3 to dry the raw materials. After the raw materials are dried, the motor 11 drives the gear 12 to rotate. The gear 12 drives the sliding plate 13 and the baffle 15 to deflect into the empty groove 19. Under the action of gravity, the raw materials fall between a pair of first grinding rollers 16. The motor 6 is controlled to rotate. The motor 6, through the cooperation of the transmission rod 5 and the transmission track 8, makes the pair of first grinding rollers 16 and the pair of second grinding rollers 17 rotate. The raw materials crushed by the pair of first grinding rollers 16 will be ground again by the pair of second grinding rollers 17, realizing the step-by-step grinding of the raw materials. The ground raw materials slide out along the bottom frame 9.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
