[0021] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary, and are intended to explain the utility model, and cannot be understood as the limitation of the utility model.

[0022] Reference Figs. 1-3 It is an embodiment of a kind of drug coating device of the utility model,

[0023] The pan body of coating pan 1 is uniformly distributed with through hole 4 that passes through inside and outside of pan, and is provided with tablet spraying head 2 on one side outside coating pan 1;Coating pan 1 inside middle part is further provided with mounting pipe 7, and the end of mounting pipe 7 is provided with coating spraying head 8, and coating spraying head 8 is inclinedly arranged.

[0024] The through hole 4 of the device is smaller in diameter than the medicine tablet to be coated; when the coating pot 1 rotates, the tablet will move along the inner wall of the coating pot 1 due to the friction force, and when it reaches the appropriate height, it will fall due to gravity; when the coating nozzle 8 also sprays the coating solution to the tablet, the tablet will increase the friction with the inner wall of the coating pot 1 due to the sticky coating solution on the surface, and due to inertia, it will be thrown too high when the coating pot 1 rotates, which will cause the tablet to break when it falls and hits.

[0025] The device sets the pot body of the coating pot 1 to be hollow with a plurality of through holes 4, and sets a tablet nozzle 2 outside the coating pot 1; when the tablet nozzle 2 sprays high-speed airflow, the high-speed airflow will enter the coating pot 1 through the through holes 4, and at the same time, the high-speed airflow will act on the tablet to blow it away; that is, the height of the high-speed airflow is the height at which the tablet rises with the coating pot 1, and the height of the tablet rising with the coating pot 1 can be limited by the tablet nozzle 2, so that the tablet is not broken; the yield of tablet coating is improved.

[0026] The coating pot 1 is conical in shape, and a plurality of flow guide plate stirrers 3 are arranged in the coating pot 1.

[0027] The flow guide plate stirrer 3 of the device originally places the tablet to be thrown high, and more is to have the effect of turning over the tablet, which is convenient for the tablet to be evenly coated.

[0028] The through hole 4 includes a tapered hole 41 and a straight hole 42 that are in communication with each other, the small-diameter end of the tapered hole 41 is the same in diameter as the straight hole 42, the large-diameter end of the tapered hole 41 communicates with the external environment of the coating pot 1, and one end of the straight hole 42 communicates with the internal environment of the coating pot 1.

[0029] The purpose of the through hole 4 of the device being set as the tapered hole 41 and the straight hole 42 is that the large aperture of the tapered hole 41 faces the tablet nozzle 2, the airflow sprayed by the tablet nozzle 2 can receive more airflow area through the guidance of the tapered hole 41, and at the same time, the design of the tapered hole can further improve the flow rate of the airflow; the purpose of the straight hole 42 is to facilitate the output of high-speed airflow to the tablet; in this way, aerodynamics can be used to improve the speed of the airflow, which is more convenient for blowing away the tablet.

[0030] The tablet nozzle 2 shell is provided with a fixed plate 5, and the lower end of the fixed plate 5 is provided with a lifting cylinder 6.

[0031] In the device, the height of the tablet nozzle 2 can be controlled by the lifting cylinder 6, and controlling the height of the tablet nozzle 2 is equivalent to controlling the height of the tablet rising; it can be adjusted according to the mass and volume of the medicine tablet to be coated, so that the device has a more extensive application space.

[0032] The sealing door is hinged to the front end of the coating pan 1, and the mounting pipe 7 is fixedly connected with the sealing door.

[0033] When the coating pan 1 rotates, the sealing door needs to be closed; and the mounting pipe 7 is fixedly connected with the sealing door, which means that the coating spray head 8 can be taken out by opening the sealing door.

[0034] The above merely describes the specific embodiments of the present application, but the technical features of the present application are not limited to this. Any changes or modifications made by those skilled in the art within the scope of the present application are covered by the patent range of the present application.
