Description

Technical Field

[0001] The utility model belongs to the technical field of screening, relates to the preparation of traditional Chinese medicine, and is particularly related to a screening device for traditional Chinese medicine pieces. Background Art

[0002] Chinese herbal medicine slices are Chinese herbal medicines that have been processed according to the theory of traditional Chinese medicine and the processing methods of traditional Chinese medicine, and can be directly used in clinical Chinese medicine. The processing flow includes cleaning, cutting, roasting, screening, etc. When screening Chinese herbal medicine slices, it is necessary to place the Chinese herbal medicine slices on the screen, and filter out the broken materials by moving the screen back and forth or vibrating the screen, and classify the Chinese herbal medicine slices into different grades. During the screening process, because the shape of the Chinese herbal medicine slices is irregular, they may get stuck in the mesh of the screen, affecting the screening efficiency. Therefore, the screen needs to be cleaned regularly. The current cleaning method is mostly to remove the screen and clean it manually, which is labor-intensive and needs further improvement.

DETAILED DESCRIPTION

[0021] 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.

[0022] The present application embodiment provides a Chinese medicine decoction piece screening device, such as Figure 1-Figure 4 As shown, it includes a rectangular screening frame 1, a reciprocating mechanism 4, a baffle 5, a rotating mechanism 3, etc.

[0023] Specifically, a first slider 101 is provided in the middle of both sides of the rectangular screening frame 1, and a pair of first sliders 101 are respectively slidably connected in a pair of U-shaped slides 2, and a strip groove 201 is opened on the outer side of a U-shaped slide 2 along its length direction, and the first slider 101 on the same side as the strip groove 201 is connected to a connecting shaft, and the connecting shaft passes through the strip groove 201 and is connected to the rotating end of the rotating mechanism 3, and the rotating mechanism 3 is slidably connected to the U-shaped slide 2 through a first sliding sleeve 301, and the rectangular screening frame 1 A connecting buckle 102 is provided at one end of the rectangular screening frame 1; a reciprocating mechanism 4 is provided at one end of the rectangular screening frame 1, and a protrusion 401 is provided on the movable end of the reciprocating mechanism 4, the protrusion 401 is connected to the connecting buckle 102, and the moving direction of the movable end of the reciprocating mechanism 4 is parallel to the length direction of the U-shaped slide 2; a baffle 5 is provided between a pair of support rods 501, and the support rods 501 are provided above a pair of U-shaped slides 2. When the rotating mechanism 3 drives the rectangular screening frame 1 to rotate a preset angle, one end of the rectangular screening frame 1 abuts against the baffle 5.

[0024] During actual use, the Chinese herbal medicines are placed in the rectangular screening frame 1, and the reciprocating mechanism 4 is controlled to drive the rectangular screening frame 1 to move back and forth to perform screening. After the screening is completed, the rotating mechanism 3 is controlled to drive the rectangular screening frame 1 to rotate so that it collides with the baffle 5 multiple times to shake the material, and the Chinese herbal medicines stuck in the rectangular screening frame 1 are shaken out.

[0025] Specifically, the rotating mechanism 3 can be a rotating cylinder or a servo motor. Figure 1The reciprocating mechanism 4 includes a rotating disk 402, a driving motor 403, and a connecting rod 404. The rotating disk 402 is coaxially connected to the output shaft of the driving motor 403. A first rotating shaft 4021 is eccentrically arranged on the top surface of the rotating disk 402. One end of the connecting rod 404 is rotatably connected to the first rotating shaft 4021. The other end of the connecting rod 404 is rotatably connected to a second sliding sleeve 4042 through a second rotating shaft 4041. The protrusion 401 is arranged on the top of the second sliding sleeve 4042. The second sliding sleeve 4042 is slidably connected to a slide rail 405. The length direction of the slide rail 405 is parallel to the length direction of the U-shaped slide 2. The bottom of the slide rail 405 is fixed to a support plate 406. The support plate 406 is arranged at the bottom of the U-shaped slide 2. The driving motor 403 can be fixed below the support plate 406 so that its output shaft passes through the support plate 406 and is connected to the rotating disk 402. By controlling the driving motor 403 to drive the rotating disk 402 to rotate, one end of the connecting rod 404 can be moved along with the first rotating shaft 4021, and then the other end of the connecting rod 404 drives the second sliding sleeve 4042 and the rectangular screening frame 1 to perform reciprocating motion. Compared with reciprocating mechanisms 4 such as cylinders and screws, it drives the rectangular screening frame 1 to move back and forth faster and has a higher screening efficiency. Compared with cylinders, screws, etc., the driving motor 403 only needs to keep rotating in one direction, and there is no need to repeatedly change the driving direction.

[0026] Preferably, see Figure 3 , the ends of both sides of the rectangular screening frame 1 away from the reciprocating mechanism 4 are provided with second sliders 103 matching the U-shaped slide 2. When the movable end of the reciprocating mechanism 4 drives the rectangular screening frame 1 to be pushed out to the maximum distance, the second slider 103 is outside the U-shaped slide 2. When the second slider 103 is inside the U-shaped slide 2, it can cooperate with the first slider 101 to prevent the rectangular screening frame 1 from rotating and avoid stress on the connecting shaft.

[0027] Specifically, when the movable end of the reciprocating mechanism 4 drives the rectangular screening frame 1 to be pushed out to the maximum distance, the distance between the baffle plate 5 and one end of the rectangular screening frame 1 in the horizontal direction is greater than the distance between the baffle plate 5 and the other end of the rectangular screening frame 1 in the horizontal direction. That is, when one end of the rectangular screening frame 1 is rotated upward by more than 90 degrees, it abuts against the baffle plate 5, so that the Chinese herbal medicine pieces in the rectangular screening frame 1 can be poured out.

[0028] Preferably, see Figure 2 A transverse groove 5011 is provided at the top of the inner side of the support rod 501, and the two ends of the baffle 5 are respectively slidably connected in the two transverse grooves 5011. The end of the transverse groove 5011 away from the reciprocating mechanism 4 is connected to one end of a spring 5012, and the other end of the spring 5012 is connected to the baffle 5. When the rectangular screening frame 1 collides with the baffle 5, the spring 5012 can produce a buffering effect.

[0029] The above are only some of the embodiments listed in this application and are not intended to limit this application.
