[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1: Reference Figure 1-Figure 4The automatic feeding device for dispensing Chinese herbal medicine slices shown in the figure includes an automatic dispensing cabinet 1, a hopper mechanism 2 and a feeding mechanism 3. The upper end of the automatic dispensing cabinet 1 is fixedly installed with a first slide rail 101, and a second slide rail 102 is slidably installed on the first slide rail 101. The hopper mechanism 2 is slidably installed on the second slide rail 102. The hopper mechanism 2 includes a transition bin 201 and a separation hopper 202. The separation hopper 202 is provided with a plurality of first troughs. The lower end of the separation hopper 202 is fixedly installed with a cylinder 217, and the cylinder 217 is provided with a plurality of material passing channels. , each of the feeding channels is communicated with the corresponding first trough, and a support plate support 219 and a plurality of support plates 218 are rotatably installed at the lower end of the cylinder 217. Each of the support plates 218 is arranged in the corresponding feeding channel. The rotation of the support plate support 219 can drive the support plates 218 to rotate one by one. A linkage shaft 212 is rotatably installed on the transition bin 201, and a linkage component is installed at one end of the linkage shaft 212. Bottom plates 205 are symmetrically rotatably installed on both sides of the bottom of the transition bin 201. The linkage shaft 212 can drive the two bottom plates 205 through the linkage component. 5 rotates synchronously in opposite directions. A ratchet assembly is installed at the other end of the linkage shaft 212. The linkage shaft 212 can drive the support plate support 219 to rotate in one direction through the ratchet assembly. When the present invention starts working, the feeding mechanism 3 can lift multiple materials at the same time and then transport them to the separation hopper 202. One of the support plates 218 is in a vertical downward state, and the corresponding medicinal materials fall into the transition bin 201. The hopper mechanism 2 is moved to the corresponding position by using the first slide rail 101 and the second slide rail 102. When the linkage shaft 212 drives the two bottom plates 205 to flip outward, The pallet support 219 does not rotate, and the discharge of one medicinal material is completed. Then, when the linkage shaft 212 drives the two bottom plates 205 to flip inward, the pallet support 219 rotates. When the bottom plate 205 is reset, the next pallet 218 flips to vertically downward, and the corresponding medicinal material falls into the transition bin 201. The above operation is repeated to complete the discharge of another medicinal material. Through the above structural setting, the hopper mechanism 2 can discharge multiple medicinal materials one by one, so that the present invention can continuously replenish multiple medicinal materials without the hopper mechanism 2 frequently returning to the loading point, simplifying the operating steps and improving the replenishment efficiency.

[0039] The upper end of the automatic dispensing cabinet 1 is provided with multiple feeding ports, and a dust cover 103 is installed in the feeding port. The dust cover 103 includes two flip plates, and the two flip plates are symmetrically mounted on the inner wall of the feeding port, and a torsion spring is fixedly installed between the lower end of the flip plate and the inner wall of the feeding port. When the hopper mechanism 2 discharges the material, the bottom plate 205 flips outward to push the two flip plates to flip into the feeding port. After the bottom plate 205 is reset, the flip plate is reset under the action of the torsion spring, so that the dust cover 103 can prevent dust and debris from entering the feeding port without affecting the feeding.

[0040] The difference between the embodiment 2 and the above embodiment is that Figure 5-Figure 7 As shown, the linkage assembly includes a rotating rod 209, a first linkage rod 207 and a second linkage rod 208, the middle part of the rotating rod 209 is fixedly connected to one end of the linkage shaft 212, one end of the first linkage rod 207 is rotatably connected to one end of the rotating rod 209, the other end of the first linkage rod 207 is rotatably connected to the middle part of one of the base plates 205, one end of the second linkage rod 208 is rotatably connected to the other end of the rotating rod 209, and the other end of the second linkage rod 208 is rotatably connected to the middle part of the other base plate 205. The linkage shaft 212 is rotated forward, and the linkage shaft 212 drives the rotating rod 209 to rotate forward. Through the transmission action of the first linkage rod 207 and the second linkage rod 208, the two base plates 205 are driven to flip outward. The linkage shaft 212 is rotated backward, and the two base plates 205 are driven to flip inward, which facilitates the control of the discharge of medicinal materials in the transition bin 201.

[0041] The ratchet assembly includes a dial 213, a pawl 214, a leaf spring 215 and an inner ratchet 216. The dial 213 is fixedly connected to the other end of the linkage shaft 212. The pawl 214 is rotatably mounted on the edge of the dial 213. The leaf spring 215 is fixedly mounted on the edge of the dial 213. One end of the leaf spring 215 contacts the pawl 214. The inner ratchet 216 is rotatably mounted on the inner wall of the transition bin 201. The inner ratchet 216 is coaxially arranged with the dial 213, and the inner ratchet 216 cooperates with the pawl 214. By controlling the setting direction of the pawl 214 and the inner ratchet 216, the inner ratchet 216 can be made not to rotate when the linkage shaft 212 rotates forward, and the inner ratchet 216 can rotate when the linkage shaft 212 rotates reversely.

[0042] A mounting bracket 210 is fixedly mounted on the outer wall of the transition bin 201 , and a first motor 211 is fixedly mounted on the mounting bracket 210 . The output end of the first motor 211 is fixedly connected to one end of a linkage shaft 212 , so that the linkage shaft 212 can be driven to rotate forward and reversely by the first motor 211 .

In the initial state, the gap The position corresponds to one of the support plates 218, and the medicinal materials in the first material trough corresponding to the support plate 218 directly fall into the transition bin 201. The rotation of the inner ratchet 216 can drive the support plate support 219 to rotate. By controlling the diameter ratio of the inner ratchet 216 and the toothed ring, the linkage shaft 212 drives the two bottom plates 205 to return from the maximum outward-turned state. At the same time, the notch of the fan ring just rotates to the position corresponding to the next support plate 218, and the next medicinal material falls into the transition bin 201. Continuous reciprocating driving of the linkage shaft 212 can achieve continuous feeding.

The material box 302 can be loaded with a variety of medicinal materials at one time, and a variety of medicinal materials can be discharged through different discharge channels.

[0045] The hopper mechanism 2 also includes a first feed pipe 203 and a second feed pipe 204. A cover plate 206 is fixedly installed on the upper end of the separation hopper 202. The first feed pipe 203 and the second feed pipe 204 are both fixedly installed on the upper end of the cover plate 206. A plurality of feed channels are provided in the first feed pipe 203 and the second feed pipe 204. Each feed channel is connected to the corresponding first feed trough. By adding medicinal materials into each feed channel, the medicinal materials can be added to the separation hopper 202.

[0046] The elevator 301 can drive the material box 302 to rise and fall. When the material box 302 rises to the highest point, the first feed pipe 203 is connected with the first discharge pipe 303, the second feed pipe 204 is connected with the second discharge pipe 304, and each of the feed channels is connected with the corresponding discharge channel. The elevator 301 is used to lift the medicinal materials, and the lifted medicinal materials are automatically transferred, which greatly improves the convenience of the loading process.

[0047] The first feeding pipe 203 and the second feeding pipe 204 both include a first vertical section and a first inclined section, the lower ends of the two first vertical sections are fixedly connected to the cover plate 206, and each first inclined section is fixedly installed at the upper end of the corresponding first vertical section; the first discharge pipe 303 and the second discharge pipe 304 both include a second vertical section and a second inclined section, the upper ends of the two second vertical sections are fixedly connected to the material box 302, and each second inclined section is fixedly installed at the lower end of the corresponding second vertical section. The arrangement of the first oblique section and the second inclined section ensures that the medicinal materials are fed into the first feeding pipe 203, the second feeding pipe 204, the first discharge pipe 303 and the second discharge pipe The tubes 304 can all be moved by gravity, the end faces of one end of the two first inclined sections are vertically arranged, the end faces of one end of the two second inclined sections are vertically arranged, and the end faces of one end of the two first inclined sections are respectively in the same plane with the end faces of one end of the two second inclined sections, ensuring that when the first discharge tube 303 and the second discharge tube 304 rise to a certain height, the end faces of one end of the two first inclined sections respectively coincide with the end faces of one end of the two second inclined sections, the first discharge tube 303 is connected to the first feeding tube 203, and the second discharge tube 304 is connected to the second feeding tube 204, and various medicinal materials can be transferred under the action of gravity.

[0048] Example 5 is different from the above embodiment in that one end of the two second inclined sections is equipped with a blocking assembly 305, and the blocking assembly 305 includes a blocking plate 3051 and a blocking plate frame 3052. The blocking plate 3051 is arranged to fit the end face of the second inclined section, and sliding protrusions 3053 are symmetrically fixedly installed on both sides of the blocking plate 3051. Slide grooves are symmetrically provided on both sides of the blocking plate frame 3052. Each of the sliding protrusions 3053 is arranged in a corresponding slide groove, and a guide rod 3054 is fixedly installed in the two slide grooves.

The bottom plate 205 acts on the dust cover 103, pushing the dust cover 103 open, and the medicinal materials enter the corresponding feeding port.

[0054] The first motor 211 is driven to drive the linkage shaft 212 to rotate in the opposite direction, and the linkage shaft 212 drives the rotating rod 209 to rotate in the opposite direction, driving the two bottom plates 205 to flip inward. While the linkage shaft 212 rotates in the opposite direction, it drives the dial 213 to rotate, and the pawl 214 acts on the inner ratchet 216 to drive it to rotate. The inner ratchet 216 drives the support plate support 219 to rotate, and the fan ring rotates and pushes the above-mentioned support plate 218 to flip upward. When the two bottom plates 205 are reset, the notch of the fan ring rotates to the next support plate 218, and the support plate 218 flips downward. The medicinal materials in the corresponding first trough fall into the transition bin 201 through the material transfer channel;

[0055] The hopper mechanism 2 is moved to the top of the corresponding feeding port through the cooperation of the first slide rail 101 and the second slide rail 102, and the above operation is repeated to feed the various medicinal materials one by one.
