[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0019] like Figure 1-Figure 3 As shown, this example provides a medicine powder feeding device, including: a support seat 100, a feeding mechanism 200, and a bearing mechanism 300.

[0020] The support seat 100 is installed on the tank body; the feeding mechanism 200 includes two support rings 201 which are respectively arranged on both sides of the support seat 100 and are symmetrically arranged. One end of the support ring 201 is located on the diameter of the support seat 100. A carrier frame 202 rotating along its central axis is provided between the support rings 201. A scraper 203 rotating around its own axis is provided on the carrier frame 202. A plurality of clamping plates 204 are provided on both sides of the scraper 203 in the vertical direction. The clamping plates 204 on both sides of the scraper 203 are symmetrically arranged and move toward each other, and are used to clamp the powder barrel. After the carrier frame 202 rotates 180 degrees, the scraper 203 is located directly above the mouth of the tank body, so that the powder in the powder barrel can fall smoothly into the tank body; the bearing mechanism 300 is installed below the support seat 100, including a support plate 301 moving in the vertical direction, which is used to carry the powder barrel to facilitate the clamping of the powder barrel by the clamping plate 204.

[0021] Specifically, an arc-shaped limiting groove 205 is provided on the side of the support ring 201 along its trajectory, and a connecting shaft 206 is passed through the limiting groove 205. One end of the connecting shaft 206 is connected to the carrier frame 202, and a connecting rod 207 is also sleeved on the connecting shaft 206. One end of the connecting rod 207 is sleeved on the first transmission shaft 208. The first transmission shaft 208 is rotatably installed on the cross plate 209, and one end is connected to the output end of the first power device. The cross plate 209 is installed on the support ring 201, and the axis of the first transmission shaft 208 is aligned with the limiting groove. The axis of 205 is coaxial. After the clamping plate 204 clamps the powder barrel, the first transmission shaft 208 can be driven to rotate by the first power device, and the connecting rod 207 starts to rotate around the axis of the first transmission shaft 208, so that the carrier 202 rotates synchronously, and then the powder barrel is turned over 180 degrees, and it is ensured that the powder barrel is directly above the tank body, so that all the powder can fall into the tank body, and in order to prevent the powder from falling outside the tank body during the turning of the powder barrel, a trumpet-shaped collecting port can be set at the upper end of the tank body.

[0022] Specifically, a through hole 210 is provided at the center of the carrier 202, and the scraper 203 is located in the through hole 210 and installed on the rotating shaft 211. A gear ring 212 is sleeved on the rotating shaft 211. The gear ring 212 is rotatably installed on the carrier 202 and meshes with the gear 213. The gear 213 is sleeved on the second transmission shaft 214. The second transmission shaft 214 is transmitted to the third transmission shaft 215 through a belt. The second transmission shaft 214 and the third transmission shaft 215 are both rotatably installed on the carrier 202, and one end of the third transmission shaft 215 is connected to the output end of the second power device. After the powder barrel is turned 180 degrees, the second transmission shaft 214 can be driven to rotate by the second power device. Driven by the belt and the meshing of the gear 213 and the gear ring 212, the scraper 203 will start to rotate around its own axis, thereby scraping the powder remaining on the inner wall of the powder barrel and ensuring that the remaining powder falls into the tank body.

[0023] Specifically, the cross-sections of the lower ends of the scraper 203 and the rotating shaft 211 are both triangular, so that the scraper 203 can enter the medicine powder barrel more smoothly when the medicine powder barrel moves upward.

[0024] Specifically, the clamping plate 204 is arc-shaped to ensure a closer contact with the outer wall of the powder barrel, and a support rod 216 is provided on the outside, one end of the support rod 216 is mounted on a movable plate 217, one end of the movable plate 217 is slidably fitted on the support frame 202, and the side is connected to the movable end of the horizontal linear mechanism, and the horizontal linear mechanism is mounted on the support frame 202. When the powder barrel needs to be clamped, the movable plates 217 are driven by the horizontal linear mechanism to move toward each other, thereby clamping the powder barrel.

[0025] Specifically, a clamping plate 218 is further provided at one end of the movable plate 217. The clamping plate 218 is arc-shaped and has an inner diameter smaller than the inner diameter of the clamping plate 204. The distance between the clamping plate 218 and the clamping plate 204 located at the top is equal to the thickness of the flange of the powder barrel. When the clamping plate 204 is used to clamp the powder barrel, the flange of the powder barrel is located between the clamping plate 218 and the clamping plate 204, thereby limiting the end of the powder barrel and preventing the powder barrel from slipping after following the support frame 202 to flip 180 degrees.

[0026] Specifically, both ends of the support plate 301 are connected to the moving end of the vertical lifting mechanism, and the vertical lifting mechanism is installed at the bottom of the support seat 100. A limiting ring 302 is provided on the top surface of the support plate 301 to limit the side of the powder barrel to prevent the powder barrel from slipping during the up and down movement.

[0027] Since the above are only preferred embodiments of the present invention and are not intended to limit the present invention, it is obvious that those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
