DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to Figures 1-4 The present application provides a technical solution: a granule coating machine, comprising a coating machine 1, a small mouth rotating drum 2 is rotatably installed in the coating machine 1, a first spiral plate 201 and a second spiral plate 202 are fixedly connected to the inner wall of the small mouth rotating drum 2, the second spiral plate 202 and the first spiral plate 201 are arranged in an annular array, a conveying pipe 3 is fixedly connected to the rear of the coating machine 1 through a support, the conveying pipe 3 passes through the rear of the small mouth rotating drum 2, a plurality of spraying pipes 301 are fixedly connected to the conveying pipe 3, a discharge port 203 is formed in the small mouth rotating drum 2 and is located close to the rear edge, a discharge inclined plate 6 is fixedly connected to the coating machine 1 and is located below the small mouth rotating drum 2, a vibration motor 601 is fixedly connected to the lower surface of the discharge inclined plate 6, a heating pipe 602 is embeddedly installed in the discharge inclined plate 6, and a baffle 7 is arranged above the discharge inclined plate 6.

[0023] In this embodiment, by placing the particles to be coated into the small mouth drum 2, connecting the drug supply device with the delivery pipe 3, using the drug supply device to deliver the liquid medicine to the delivery pipe 3, and then spraying it into the small mouth drum 2 using the spray pipe 301, the first spiral plate 201 and the second spiral plate 202 will rotate when the small mouth drum 2 rotates. The number ratio of the first spiral plate 201 to the second spiral plate 202 is 4:2, and the spiral directions are opposite. The first spiral plate 201 can drive the particles to move backward, and the second spiral plate 202 can drive the particles to move forward. Thus, the particles move four steps backward and two steps forward in the small mouth drum 2, which prolongs the rolling time of the particles in the small mouth drum 2 and enables the medicine to be fully wrapped on the surface of the particles. When the particles move to the position at the rear end of the small mouth drum 2, they will be discharged onto the discharge inclined plate 6 through the discharge port 203. Starting the heating pipe 602 can heat the discharge inclined plate 6 to dry and harden the medicine on the surface of the particles falling on the discharge inclined plate 6. Starting the vibration motor 601 can drive the discharge inclined plate 6 to vibrate, which helps the particles slide down along the discharge inclined plate 6. The baffle 7 is located above the discharge inclined plate 6, and a certain gap is left between the lower end of the baffle 7 and the discharge inclined plate 6, which can limit the particles from piling up and sliding down, so that the particles can be laid flat on the discharge inclined plate 6 and slide out, enabling the particles to contact the bottom of the discharge inclined plate 6 and avoid uniform drying of the liquid medicine.

[0024] In order to achieve the purpose of driving the small mouth drum 2 to rotate, the device adopts the following technical scheme: the coating machine 1 is fixedly connected with a feed hopper 101 on the front side, the small mouth drum 2 is fixedly connected with a connecting shaft pipe 204 at the rear, the connecting shaft pipe 204 is fixedly connected with a driven belt pulley 205, a drive motor 5 is arranged at the rear of the coating machine 1, the output end of the drive motor 5 is fixedly connected with a driving belt pulley 501, and the driving belt pulley 501 and the driven belt pulley 205 are linked through a transmission belt 502.

The driving belt pulley 501 and the driven belt pulley 205 are linked through the transmission belt 502. Thus, the rotation of the driving belt pulley 501 will drive the driven belt pulley 205 to rotate through the transmission belt 502. The rotation of the driven belt pulley 205 will drive the connecting shaft pipe 204 to rotate, thereby driving the small mouth drum 2 to rotate.
