Description

Technical Field

[0001] The utility model belongs to the field of screening equipment for traditional Chinese medicine decoction pieces processing, and specifically relates to a multi-stage screening device for traditional Chinese medicine decoction pieces processing. Background Technique

[0002] A screening device is a device used to separate solid materials. Its main function is to screen according to the size of the materials to achieve the purpose of classification, separation, or cleaning. These devices are widely used in various industrial and processing processes. Traditional Chinese medicine decoction pieces are drinks made from traditional Chinese herbs and usually have medicinal and health care functions. Through the formula and processing technology of traditional Chinese medicine materials, drinks with specific effects are made. During the processing, a screening device is needed to screen the raw materials of the herbs to make them uniform;

[0003] According to the Chinese patent application number: 202322679401.1, there is disclosed a multi-stage screening device for traditional Chinese medicine decoction pieces processing, which relates to the technical field of traditional Chinese medicine processing. It includes a housing and a screening mechanism arranged inside the housing. By setting a first motor to rotate and drive an eccentric turntable to rotate, since the connection between the first motor and the eccentric turntable is an eccentric connection, when the eccentric turntable rotates, it will continuously hit the vibration block and make the vibration block slide on the outer wall of the sliding column, and the spring will push the vibration block back, so a vibration structure is formed, and then it drives the large-hole sieve plate above to vibrate and screen. Then, when the smaller traditional Chinese medicine materials are screened down, the larger traditional Chinese medicine materials will be left at the top of the large-hole sieve plate. Then, the smaller traditional Chinese medicine materials will fall onto the small-hole sieve plate, and the smaller traditional Chinese medicine materials will be screened out, while the smaller traditional Chinese medicine materials will fall onto the small-hole sieve plate. Two-layer screening can screen the traditional Chinese medicine materials into three sizes: large, medium, and small;

[0004] The prior art effectively solves the problem that traditional screening devices are not very easy to separate traditional Chinese medicine into different volume sizes and need to be further subdivided, which is inconvenient for people to use. It has the advantage of being convenient to separate traditional Chinese medicine by volume size. However, when using this multi-stage screening device, multiple sets of driving devices are required for screening, so a large amount of energy consumption is needed to carry out the screening operation, thereby increasing the processing cost of traditional Chinese medicine decoction pieces.

[0022] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings. In the present disclosure, aspects of the present utility model are described with reference to the drawings, and many illustrative embodiments are shown in the drawings. The embodiments of the present disclosure do not have to define all aspects of the present utility model. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in the present utility model are not limited to any implementation manner. In addition, some aspects of the present utility model can be used alone, or in any suitable combination with other aspects of the present utility model.

[0023] Embodiment 1

[0024] As Figures 1-4 shown, this is the first embodiment of the present utility model. This embodiment provides a multi-stage screening device for processing traditional Chinese medicine decoction pieces, including a base 1. A screening assembly 2 is installed on the top of the base 1. The screening assembly 2 includes a first frame 201, a second frame 202, a third frame 203, a sieve mesh 204, a hopper 205, a discharge pipe 206, and a top cover 207. Sieve meshes 204 are installed in the inner cavities of the first frame 201, the second frame 202, and the third frame 203. The hopper 205 is installed at the bottom of the third frame 203, and the top cover 207 is installed on the top of the first frame 201. The screening assembly 2 is used for screening traditional Chinese medicine step by step. A vibration assembly 3 is installed between the base 1 and the hopper 205. The vibration assembly 3 includes a vibration motor 301 and a spring 302. The vibration assembly 3 is used to provide vibration energy. A cleaning assembly 5 is installed in the inner cavity of the screening assembly 2. The cleaning assembly 5 includes a main shaft 501, a push plate 502, and a brush plate 503. There are three groups of push plates 502 and brush plates 503, which are respectively installed in the inner cavities of the first frame 201, the second frame 202, and the third frame 203. A driving assembly 4 is installed on the top of the top cover 207. The driving assembly 4 includes a servo motor 401 and a reducer 402. The driving assembly 4 is used to provide power for the cleaning assembly 5.

[0025] As Figures 1-4 shown, a feed inlet is also provided on the top of the top cover 207 for adding traditional Chinese medicine materials to be screened. The vibration energy generated by the vibration motor 301 causes the screening assembly 2 to shake through the spring 302, so as to drive the traditional Chinese medicine materials for screening. Sieve meshes 204 with different mesh numbers are selected for the inner cavities of the first frame 201, the second frame 202, and the third frame 203, so as to perform step-by-step screening. The servo motor 401 and the reducer 402 cooperate to drive the main shaft 501 to rotate, so that the main shaft 501 drives the push plate 502 and the brush plate 503 to rotate along the surface of the sieve mesh 204. While the push plate 502 and the brush plate 503 are rotating, they can clean and push the traditional Chinese medicine materials on the surface of the sieve mesh 204, so that the materials larger than the mesh holes are discharged and recycled through the discharge pipe 206. The hopper 205 is used to collect the screened qualified materials and discharge them through the discharge valve at the bottom. Compared with the multi-stage screening device in the comparative case, it has the characteristics of small floor area and low energy consumption during use, thus effectively reducing the processing cost of traditional Chinese medicine decoction pieces.

[0026] Embodiment 2

[0027] Referring to Figures 1-3 , this is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0028] In this embodiment, the second frame 202 is installed at the bottom of the first frame 201, and the third frame 203 is installed at the bottom of the second frame 202. The first frame 201, the second frame 202, and the third frame 203 are all connected by bolt threads.

[0029] The number of discharge pipes 206 is three, and they are respectively installed on the surfaces of the first frame 201, the second frame 202, and the third frame 203.

[0030] The first frame 201 and the top cover 207 are connected by bolt threads, and the hopper 205 and the third frame 203 are connected by bolt threads.

[0031] The number of vibration motors 301 is two, and they are respectively fixed on both sides of the bottom of the hopper 205. Both ends of the spring 302 are fixedly connected to the hopper 205 and the base 1 respectively.

[0032] As Figures 1-3 shown, the vibration energy generated by the vibration motor 301 drives the screening assembly 2 to swing through the spring 302, so that the medicinal materials can quickly pass through the screen 204. The discharge pipe 206 is used to discharge and recycle the larger medicinal materials. The bolt connection between the first frame 201, the second frame 202, and the third frame 203 facilitates disassembly and maintenance. When the screen 204 is installed, the mesh number of the screen 204 gradually decreases from top to bottom.

[0033] Embodiment 3

[0034] Refer to Figure 1 、 3 and 4, which is the third embodiment of the present invention. This embodiment is based on the first two embodiments.

[0035] In this embodiment, the servo motor 401 and the reducer 402 are both fixed on the top of the top cover 207, and the output shaft of the servo motor 401 is drivingly connected to the input shaft of the reducer 402.

[0036] One end of the push plate 502 and the brush plate 503 are both fixedly connected to the main shaft 501. One end of the main shaft 501 penetrates to the outside of the top cover 207 and is drivingly connected to the output shaft of the reducer 402.

[0037] As Figure 1 、 3 and 4 shown, the output shaft of the servo motor 401 rotates to drive the main shaft 501 to rotate through the reducer 402. When the main shaft 501 rotates, it drives the push plate 502 and the brush plate 503 to rotate along the surface of the screen 204. When the push plate 502 rotates, it can push the larger medicinal materials through the discharge pipe 206 to the outside. The brush plate 503 can clean the medicinal materials blocked in the mesh holes, thereby preventing the mesh holes from being blocked and affecting the screening efficiency.

[0038] In use, first, the traditional Chinese medicine materials to be screened are added into the inner cavity of the first frame 201 through the feeding port on the surface of the top cover 207. The vibration energy generated by the vibration motor 301 drives the screening assembly 2 to swing through the spring 302, so that the materials can quickly pass through the screen 204. The materials sequentially enter the inner cavities of the second frame 202 and the third frame 203 and are screened through the screen 204. The qualified screened materials fall into the inner cavity of the hopper 205 for collection. The output shaft of the servo motor 401 rotates to drive the main shaft 501 to rotate through the speed reducer 402. When the main shaft 501 rotates, it drives the push plate 502 and the brush plate 503 to rotate along the surface of the screen 204. When the push plate 502 rotates, it can push the larger materials to the outside through the discharge pipe 206. The brush plate 503 can clean the materials blocked in the mesh holes, thereby preventing the mesh holes from being blocked and affecting the screening efficiency. Compared with the multi-stage screening device in the comparative case, it has the characteristics of small floor area and low energy consumption during use, thus effectively reducing the processing cost of traditional Chinese medicine decoction pieces.
