DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-3 This application is described in further detail.

[0024] The present application embodiment discloses a Chinese medicine slice screening machine. Figure 1-3 A Chinese medicine slice screening machine comprises a bracket 1 fixed on a designated mounting surface, a plurality of auxiliary support components 4 are mounted on the bracket 1, a reinforcing ring 3 is supported by the auxiliary support components 4 for rolling support, a reinforcing ring 3 is installed on the upper side of the auxiliary support components 4 for rolling support, the reinforcing ring 3 is used to increase the overall strength of an outer cylinder 201 to prevent the outer cylinder 201 from being deformed by force, a same screening component 2 is installed on the inner side of a plurality of reinforcing rings 3, the screening component 2 comprises an outer cylinder 201 fixedly mounted on the inner side of a plurality of reinforcing rings 3, three coaxially distributed screening cylinders 202 are installed on the inner side of the outer cylinder 201, and the two adjacent screening cylinders 202 are arranged on the inner side of the outer cylinder 201. The outer cylinder 201 and the screening cylinder 202 are sleeved with each other, and the inner walls of the outer cylinder 201 and the screening cylinder 202 are both installed with a plurality of spiral material-pickup pieces 204. The spiral material-pickup pieces 204 can be used to flip and move the material when the outer cylinder 201 and the screening cylinder 202 rotate, thereby accelerating the screening of the material by the screening cylinder 202. A driving assembly 5 is installed on the outer side of one of the reinforcing rings 3 on the bracket 1. The driving assembly 5 includes a driving motor 501 installed on the bracket 1. The driving motor 501 is connected to the reinforcing ring 3 through a transmission component. The driving motor 501 drives the reinforcing ring 3 to drive the outer cylinder 201 to rotate, so that the screening cylinder 202 rotates to flip the material.

[0025] Reference Figure 1 The auxiliary support assembly 4 includes two support rollers 401 rotatably mounted on the bracket 1, and the two support rollers 401 are located below the reinforcement ring 3. Guide rollers 402 are installed on both sides of the reinforcement ring 3 on the bracket 1. The two support rollers 401 provide rolling support for the reinforcement ring 3, and the guide rollers 402 cooperate to limit the rotation of the reinforcement ring 3 to prevent the reinforcement ring 3 from slipping during the rotation.

[0026] Reference Figure 2 The transmission component includes a gear 502 installed at the output end of the driving motor 501. The reinforcing ring 3 is provided with a tooth groove adapted to the gear 502. The gear 502 is meshed with the tooth groove. The driving motor 501 drives the gear 502 to rotate, thereby driving the reinforcing ring 3 and the outer cylinder 201 to rotate, so that the screening cylinder 202 rotates.

[0027] Reference Figure 3 The spiral material-prying pieces 204 are of the same length as the screening cylinder 202 and are installed axially along the screening cylinder 202. The spiral material-prying pieces 204 are respectively distributed in an annular manner on the inner walls of the outer cylinder 201 and the screening cylinder 202, and the spiral directions of the two adjacent layers of spiral material-prying pieces 204 are opposite. When the outer cylinder 201 and the screening cylinder 202 rotate in the same direction, the spiral material-prying pieces 204 will flip the Chinese herbal medicine pieces to both sides along the spiral direction, thereby realizing that the movement directions of the two adjacent layers of materials are opposite, extending the screening path, and ensuring the screening effect.

[0028] Reference Figure 3 The sieve hole diameters of the three screening cylinders 202 decrease from the inside to the outside. A plurality of discharge ports 7 are installed at one end of the outermost screening cylinder 202 along the material moving direction. A plurality of discharge ports 8 are installed at both ends of the outer cylinder 201. The discharge ports 7 are radially aligned with the discharge ports 8 on the corresponding side. The screening cylinders 202 are used to perform multi-stage screening on the Chinese herbal medicines. The screened Chinese herbal medicines on the two inner screening cylinders 202 are discharged through the ports. The screened Chinese herbal medicines on the outermost screening cylinder 202 are discharged through the discharge port 7. The broken residues and small particle impurities on the outer cylinder 201 are discharged through the discharge port 8.

[0029] Reference Figure 2 Both ends of the outer cylinder 201 are connected with a plurality of connecting plates 203 by bolts, and a plurality of bolt holes are installed on the three screening cylinders 202. The inner threads of the bolt holes are installed with fastening bolts, and the ends of the fastening bolts pass through the connecting plates 203 and are slidably connected with the connecting plates 203.

[0030] Reference Figure 3 A feeding pipe 6 is installed on one side of the bracket 1, and the end of the feeding pipe 6 is located in the middle of the innermost screening cylinder 202. Chinese herbal medicines are added to the middle of the outer cylinder 201 through the feeding pipe 6, which facilitates the movement of the Chinese herbal medicines to both ends and ensures sufficient screening movement path.

[0031] The implementation principle of a Chinese medicine slice screening machine in the present application embodiment is:

[0032] The Chinese herbal medicine pieces to be screened are added into the screening machine through the feeding pipe 6. The Chinese herbal medicine pieces first fall into the innermost screening cylinder 202. At the same time, the driving motor 501 is started, and the gear 1 502 is driven to rotate by the driving motor 501, driving the reinforcing ring 3 and the outer cylinder 201 to rotate. Due to the installation of the spiral material-shifting piece 204, the Chinese herbal medicine pieces are shifted and moved in the spiral direction under the rotation of the screening cylinder 202, and are turned over at the same time, which speeds up the material screening. After the preliminary screening of the Chinese herbal medicine pieces, the pieces with larger particles continue to remain in the current The pieces of Chinese medicine are placed on the screening cylinder 202 of the first layer, while the pieces of medicine with smaller particles fall into the screening cylinder 202 of the next layer through the sieve holes. Under the action of the spiral material-pickling piece 204 of the next layer, the pieces of Chinese medicine move in the direction. Since the sieve holes of the three screening cylinders 202 decrease from the inside to the outside, multi-stage screening can be achieved to obtain pieces of medicine with different particle size ranges. After multi-stage screening, the pieces of medicine on the innermost screening cylinder 202 are finally discharged through the discharge port 7, and the pieces of medicine on the outermost screening cylinder 202 are discharged through another discharge port 7. The broken slag and small particle impurities on the outer cylinder 201 are discharged through the discharge port 8. When the screening is completed, the driving motor 501 is turned off to stop the operation of the screening machine. Then, the screening machine can be cleaned as necessary for the next use.
