Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine screening technology, and in particular to a raw material screening device for traditional Chinese medicine processing with a regulating function. Background Technology

[0002] Screening devices are tools used to separate materials. Screening uses a sieve to allow fine particles smaller than the sieve holes to pass through the sieve surface, while coarse particles larger than the sieve holes remain on the sieve surface, thus completing the process of separating coarse and fine materials. In the process of processing and producing traditional Chinese medicine, raw material screening is a key link to ensure the quality of medicinal materials. Chinese medicine raw materials (such as decoction pieces, granules, etc.) need to be screened to remove impurities and separate materials of different particle sizes in order to meet the requirements of subsequent processing, extraction and other processes.

[0003] Existing Chinese herbal medicine screening devices mostly use fixed parameters for shaking amplitude, which makes it difficult to adapt to the characteristics of diverse Chinese herbal medicine raw materials. For example, chrysanthemum and sophora flowers, which are brittle, are easily broken by excessive shaking, while ginseng and notoginseng, which are more viscous, require greater shaking amplitude for effective screening. Fixed amplitude cannot flexibly match different screening needs, often resulting in incomplete screening leading to impurity residue or excessive breakage leading to loss of effective components, which seriously affects the quality and efficacy of Chinese herbal medicine products. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when screening Chinese medicine, the shaking amplitude is mostly fixed parameters, which easily leads to incomplete screening or excessive shaking causing the medicinal materials to break, seriously affecting the quality and efficacy of Chinese medicine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A raw material screening device for processing traditional Chinese medicine with adjustable function includes a screening box, the screening box being provided with a convenient replacement mechanism inside;

[0007] The convenient replacement mechanism includes a screening box, on which symmetrically distributed sliding blocks are fixedly connected to the front and back sides. Sliding rods are slidably sleeved on the inner walls of the sliding blocks. The two ends of the two sliding rods are respectively fixedly connected to the inner walls of the two sides of the screening box. A through groove is opened on the inner bottom wall of the screening box, and a sieve plate is movably sleeved on the inner wall of the screening box.

[0008] A shaking adjustment mechanism is provided on one side of the screening box.

[0009] Preferably, the upper end of the screening box is provided with a feeding port, and the lower end of the screening box is fixedly connected to a collecting guide hopper.

[0010] Preferably, the front of the screening box is hinged to a sealed door, and the front of the sealed door is provided with an observation window.

[0011] Preferably, the shaking adjustment mechanism includes a drive rod, one end of which is fixedly connected to one side of the screening box, and the other end of which extends through to one side of the screening box and is fixedly connected to a drive block.

[0012] Preferably, the upper end of the drive block is provided with a drive groove, and the two sides of the screening box are fixedly connected with a pair of support blocks, one of which is fixedly mounted with a servo motor at its upper end.

[0013] Preferably, the output shaft of the servo motor is fixedly mounted with a rotating shaft via a coupling. A drive disk is fixedly sleeved on one end of the rotating shaft. A movable groove is opened at the upper end of the drive disk. A lead screw is rotatably connected to the rear inner wall of the movable groove via a bearing.

[0014] Preferably, one end of the lead screw extends through to the outside of the drive disc and is fixedly connected to an adjusting handle. A moving block is threadedly connected to the outside of the lead screw. The outside of the moving block is slidably connected to the inner wall of the moving groove. A lever is fixedly connected to the upper end of the moving block. The outside of the lever is slidably sleeved with the inner wall of the drive groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Example

[0027] like Figure 1-4As shown, this utility model provides a technical solution: a raw material screening device for processing traditional Chinese medicine with adjustable function, including a screening box 1. The screening box 1 serves as the main body of the device and integrates a feeding port 25, a collecting guide hopper 26, a sealing door 27, and an observation window 28. The feeding port 25 enables centralized feeding of raw materials to avoid spillage. A cover plate can be installed above the feeding port 25 to prevent dust from overflowing. Since this belongs to the prior art, it is not shown in the figure.

[0028] The collecting hopper 26 guides the undersize material to gather and collect, improving the material collection efficiency. The sealing door 27, together with the observation window 28, not only ensures the sealing of the screening operation, but also allows for real-time monitoring of the screening status, such as material accumulation and screen plate blockage, providing convenience for operation and maintenance.

[0029] The screening box 2 is the supporting unit of the screening plate 24. The sliding blocks 21 on its front and back are slidably connected with the sliding rod 22 in the screening box 1 to form a guide structure. When the screening box 2 shakes left and right, the sliding blocks 21 slide stably along the sliding rod 22 to ensure that the shaking trajectory is straight and without deviation, and to avoid wear of the screening plate 24 or uneven screening due to shaking deviation.

[0030] The through groove 23 on the bottom wall of the screening box 2 provides quick-release conditions for the sieve plate 24 to "move upward to detach and put directly in". When replacing the sieve plate 24, open the sealing door 27 and push the old sieve plate 24 upward from the bottom of the through groove 23 to release its sleeve constraint with the inner wall of the screening box 2.

[0031] The new sieve plate 24 is directly placed into the sieve box 2 and automatically locked in place by gravity and the connecting structure, without the need for additional fixing parts. This design is suitable for replacing sieve plates for various medicinal materials, such as pollen using fine sieve plates and rhizomes using coarse sieve plates, solving the problems of cumbersome screen replacement and long downtime in traditional devices.

[0032] The lead screw 38, moving block 310 and lever 311 in the drive disc 36 form an amplitude adjustment assembly.

[0033] Rotating the adjustment handle 39 causes the lead screw 38 to drive the moving block 310 to slide along the moving groove 37, changing the position of the lever 311 in the drive groove 32. When the lever 311 is close to the center of the rotating shaft 35, the force point of the drive groove 32 moves inward, and the shaking amplitude of the screening box 2 decreases. When the lever 311 is far away from the center of the rotating shaft 35, the force point moves outward, and the shaking amplitude increases.

[0034] The servo motor 34's speed is linked to the position of the lever 311. When the lever 311 moves inward, the motor speed is reduced synchronously through an external controller to avoid small-amplitude high-frequency shaking from aggravating material breakage. The controller is a mature existing technology, so it will not be described in detail. When the lever 311 moves outward, the motor speed increases synchronously, using large-amplitude high-frequency shaking to enhance screening efficiency, achieving coordinated adaptation of "amplitude and speed" to ensure the screening quality of different medicinal materials.

[0035] The working process of this utility model:

[0036] Step 1: When it is necessary to replace the sieve plate 24 to adapt to the new medicinal material, open the sealing door 27 on the front of the sieve box 1, push the old sieve plate 24 from the bottom of the through groove 23 upwards to make it break away from the sleeve constraint of the inner wall of the sieve box 2, take out the old sieve plate 24, clean the residual material, select the sieve plate 24 that is suitable for the new medicinal material, align the new sieve plate 24 with the top of the sieve box 2, and put it directly into the sieve box 2, ensuring that the sieve plate 24 and the sieve box 2 are stably matched.

[0037] Step 2: Set the amplitude according to the characteristics of the Chinese medicine to be screened. If chrysanthemum with a brittle texture is being screened, the amplitude should be adjusted to a small size to prevent breakage. If ginseng slices with strong viscosity are being screened, the amplitude should be adjusted to a large size to ensure thorough screening. Rotate the adjustment handle 39, and the lead screw 38 in the drive plate 36 will rotate accordingly. The moving block 310 on the lead screw 38 slides along the moving groove 37, which drives the lever 311 to move. The position of the lever 311 in the drive groove 32 changes, thereby changing the amplitude of the left and right reciprocating swaying of the screening box 2.

[0038] Step 3: Feed the Chinese herbal medicine raw materials into the feeding port 25 at the top of the screening box 1. The raw materials fall onto the sieve plate 24 inside the screening box 2. Start the servo motor 34. Under the action of the shaking adjustment mechanism, the screening box 2 shakes back and forth along the slide bar 22. The raw materials are subjected to vibration and gravity on the sieve plate 24. Materials that meet the sieve hole size pass through the sieve plate 24 and are collected by the collection guide hopper 26 at the bottom of the screening box 1. Materials that do not pass through the sieve remain on the sieve plate 24, completing the screening operation. The screening status can be viewed in real time through the observation window 28 on the front of the sealing door 27. After the screening operation is completed, open the sealing door 27 and take out the sieve plate 24 for deep cleaning.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
