Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine processing technology, and more specifically, it relates to a screening device for traditional Chinese medicine granules. Background Technology

[0002] A vibrating screen is a device specifically designed for screening materials. In the screening of Chinese medicine granules, a vibrating screen can accurately classify granules of different sizes to ensure that the Chinese medicine granules that meet the requirements are obtained. Existing vibrating screens are generally composed of a screen box, screen frame, screen mesh, vibrating motor and other parts.

[0003] Existing application number: CN202020079610.6, this utility model discloses a vibrating screen for traditional Chinese medicine, relating to the technical field of medicinal material processing. It includes a frame and a screening assembly mounted on the frame. The screening assembly includes a screen base and a driving component. The screen base is rotatably connected to the frame, and a screen parallel to its length is mounted on the screen base. The driving component includes multiple eccentric wheels, each with its lower surface rotatably connected to the upper surface of the frame. The upper surfaces of the multiple eccentric wheels are eccentrically fixedly connected to the lower surface of the screen base. When traditional Chinese medicine is placed on the screen, the rotation of the eccentric wheels causes the screen base to rotate eccentrically, thus screening the medicinal materials on the screen. Because the rotation of the eccentric wheels replaces the reciprocating motion of the first and second sliders, the range of screen movement is smaller, thus preventing the medicinal materials from falling off the screen and improving the screening effect.

[0004] Based on the above, the particle size distribution of Chinese medicine granules is uneven. If there are too many fine particles and the moisture content of the Chinese medicine granules is too high, they are easy to adhere to the mesh of the screen, resulting in poor material flow and blockage. The moist fine particles can also clump together, further aggravating the risk of blockage. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a screening device for Chinese herbal medicine granules. This device solves the problems of uneven particle size distribution in existing Chinese herbal medicine granules, excessive fine particles, and high humidity, which can cause the granules to adhere to the mesh of the screen, resulting in poor material flow and blockage. Furthermore, the damp fine particles can clump together, further exacerbating the risk of blockage.

[0006] The purpose and efficacy of this utility model's screening device for traditional Chinese medicine granules are achieved through the following specific technical means:

[0007] A screening device for traditional Chinese medicine granules, comprising a vibrating screen body;

[0008] Upper screen frame, which is disposed above the main body of the vibrating screen;

[0009] The lower discharge port is fixedly connected to the bottom of the vibrating screen body;

[0010] A transmission box, which is fixedly connected to the right side of the upper screen frame;

[0011] A drive motor is fixedly connected to the right side of the transmission box;

[0012] The connector is provided in two sets, with two connectors in each set. The two sets of connectors are distributed and fixedly connected to the front and rear sides of the upper screen frame.

[0013] The fixed guide rail is provided in two pieces, and the two fixed guide rails are respectively fixedly connected to the bottom of two sets of connecting parts;

[0014] A barrier plate, which is slidably connected to the right end of the upper screen frame;

[0015] An anti-blocking component is disposed inside the transmission box and two fixed guide rails;

[0016] A feed adjustment component is disposed inside the upper screen frame.

[0017] Furthermore, the anti-clogging component includes:

[0018] An active bevel gear is coaxially and fixedly connected to the end of the drive motor shaft;

[0019] A reciprocating lead screw, wherein two reciprocating lead screws are provided, and the reciprocating lead screw is rotatably connected to the inside of the front fixed guide rail;

[0020] The driven bevel gear is coaxially and fixedly connected to the right end of the reciprocating lead screw, and the driven bevel gear meshes with the driving bevel gear.

[0021] Furthermore, the anti-clogging component also includes:

[0022] The connecting slider is provided in two pieces, and the two connecting sliders are slidably connected inside two fixed guide rails respectively. The front connecting slider is threadedly connected to the reciprocating lead screw.

[0023] A connecting shaft is rotatably connected to the inner sides of two connecting sliders.

[0024] Furthermore, the anti-clogging component also includes:

[0025] The transmission gears are provided in two pieces, and the two transmission gears are coaxially fixedly connected to the front and rear ends of the connecting shaft respectively;

[0026] The transmission rack consists of two pieces, which are separately and fixedly connected to the lower part of the upper screen frame. The two transmission racks mesh with two transmission gears respectively.

[0027] Furthermore, the anti-clogging component also includes:

[0028] The roller brush consists of two parts, which are distributed and coaxially fixedly connected to the outside of the connecting shaft.

[0029] Furthermore, the feed adjustment assembly includes:

[0030] A connecting block, which is fixedly connected to the top front of the barrier plate;

[0031] A drive screw is rotatably connected to the top of the upper screen frame, and the drive screw is threadedly connected to the connecting block;

[0032] A knob is coaxially and fixedly connected to the top of the transmission screw.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] First, while the drive motor moves the connecting shaft left and right, it also drives the connecting shaft to rotate simultaneously through the gear and rack transmission mechanism. The connecting shaft then drives the two roller brushes to rotate, thereby cleaning the screen at the bottom of the upper screen frame. This prevents the screen mesh from becoming clogged for a long time, which could affect the screening of Chinese medicinal materials and ensure the screening efficiency of Chinese medicinal materials.

[0035] Secondly, by controlling the rotation of the transmission screw through the knob, the baffle plate can be moved up and down, thereby controlling the number of Chinese medicinal materials entering the bottom screen of the upper sieve frame at the same time. This prevents a large number of Chinese medicinal materials from rushing into the bottom screen of the upper sieve frame at the same time, causing the medicinal materials to fall out from the outlet on the left side of the upper sieve frame before being completely screened, thus giving the medicinal materials of different particle sizes and moisture levels sufficient screening time.

[0036] This invention enables a drive motor to move and rotate a connecting shaft via a gear and rack transmission mechanism, thereby driving a roller brush to clean the screen, preventing mesh blockage and ensuring the screening effect of Chinese medicine granules. At the same time, a knob controls the up and down movement of the baffle plate to control the number of Chinese medicine materials entering the screen at the same time, ensuring that the materials are fully screened and preventing them from falling off prematurely.
