Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine decoction piece screening technology, and more specifically, it relates to a traditional Chinese medicine decoction piece grading vibration screening device. Background Technology

[0002] Traditional Chinese medicine decoction pieces refer to finished products made from Chinese medicinal materials after specific processing such as cleaning, cutting, and processing under the guidance of traditional Chinese medicine theory. They can be directly used in TCM clinical prescriptions or the production of prepared Chinese medicines. In the production process of traditional Chinese medicine decoction pieces, grading and screening is one of the key processes, the purpose of which is to separate decoction pieces of different sizes and shapes according to specifications.

[0003] Currently, existing multi-stage vibration screening devices typically adopt a design mode of "independent drive for each screen layer". Each screen layer needs to be equipped with a separate vibration motor or exciter as a drive source. The setting of multiple drive sources significantly increases the equipment manufacturing and maintenance costs. Moreover, it is difficult to achieve precise synchronization of vibration parameters (such as frequency, amplitude, and phase) of different drive sources, resulting in an imbalance in the vibration state of each screen layer, which affects the grading accuracy of the same batch of medicinal slices.

[0004] To address the aforementioned issues, this application proposes a vibration screening device for grading traditional Chinese medicine decoction pieces. Utility Model Content

[0005] The purpose of this invention is to provide a vibration screening device for grading Chinese herbal medicine slices, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a vibration screening device for grading Chinese herbal medicine slices, including a screening box with a feeding hopper installed at the top, and further comprising:

[0008] Multiple screening mechanisms are evenly distributed longitudinally within the screening box. Each screening mechanism includes a guide plate and an inclined screen plate. The top surface of the guide plate is inclined, and the inclination direction is opposite to that of the screen plate.

[0009] Screening mechanism two is located below screening mechanism one. Screening mechanism two includes guide plate two and inclined screen plate two. The top surface of guide plate two is inclined and the inclination direction is the same as that of screen plate one.

[0010] Both screening mechanism one and screening mechanism two are provided with eccentric blocks below them, and the eccentric blocks are respectively connected to the rotating shaft one through a transmission mechanism.

[0011] The screening box is provided with multiple guide plates three on one side, and the guide plates three are fixedly connected to the screen plate one, the screen plate two and the guide plate two respectively.

[0012] Furthermore, the guide plate has a discharge port, and the discharge port has a lower end of the guide plate.

[0013] Furthermore, a fixing plate is fixedly provided on the bottom surface of the lower end of the screen plate and the top surface of the guide plate, and a fixing rod is fixedly provided on the top end of the higher end of the screen plate and the top surface of the guide plate.

[0014] Furthermore, a fixing rod is fixed between the lower end of the screen plate two and the top surface of the guide plate two, and a fixing plate two is fixed between the higher end of the screen plate two and the guide plate two.

[0015] Furthermore, the transmission mechanism includes a second rotating shaft fixedly connected to the eccentric block, and the second rotating shaft is rotatably installed inside the screening box. The second rotating shaft is fixedly connected to a first bevel gear through a connecting shaft, and the first bevel gear and the second bevel gear are meshed together. The second bevel gear is fixedly connected to the outer wall of the first rotating shaft. Both the first bevel gear and the second bevel gear are disposed inside the outer protective shell, and a motor for driving the first rotating shaft to rotate is provided above the outer protective shell.

[0016] Furthermore, a smoothing rod is fixedly provided at the bottom end of both the first guide plate and the second guide plate, and the smoothing rod passes through the bottom end of the fixed seat and is slidably connected to the fixed seat. The fixed seat is fixedly connected to the inner wall of the screening box, and a slider fixedly connected to the bottom end of the smoothing rod is slidably provided inside the fixed seat. A spring is fixedly provided between the top end of the slider and the fixed seat, and the spring is wound around the smoothing rod.

[0017] Furthermore, a discharge port is provided on one side wall of the screening box, and the discharge port is penetrated by a guide plate.

[0018] Furthermore, the mesh size of the first sieve plate arranged from top to bottom decreases sequentially, and the mesh size of the bottommost first sieve plate is larger than that of the second sieve plate.

[0019] This utility model has the following beneficial effects:

[0020] This invention uses a single rotating shaft to synchronously drive all eccentric blocks through the transmission mechanism, enabling each level of the screening mechanism to generate coordinated vibrations under the drive of a single driving source. This avoids the need to configure a separate driving source for each layer of screen, which simplifies the structure and ensures the synchronicity and stability of the screening actions of each layer, thereby improving screening efficiency and grading accuracy.

[0021] In this utility model, the top surface of the guide plate of the screening mechanism is inclined in the opposite direction to the inclination direction of the screen plate. Through the reverse inclined guide structure, the material can be guided to be more evenly dispersed on the surface of the lower screen plate during the screening process, thereby improving the screening efficiency of a single screening.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1 - Figure 4 As shown, this utility model is a vibration screening device for grading Chinese herbal medicine slices, including a screening box 1 with a feed hopper 101 installed at the top, and further including: multiple screening mechanisms 1 2, which are evenly distributed longitudinally in the screening box 1. Each screening mechanism 1 2 includes a guide plate 202 and an inclined screen plate 201. The top surface of the guide plate 202 is inclined, and the inclination direction is opposite to that of the screen plate 201. Screening mechanism 2 3 is located below the screening mechanisms 1 2, and the screening mechanism 2 3 includes... The screening box 1 includes a second guide plate 302 and an inclined screen plate 301. The top surface of the second guide plate 302 is inclined, and the inclination direction is the same as that of the first screen plate 201. An eccentric block 10 is provided below both the first screening mechanism 2 and the second screening mechanism 3, and the eccentric block 10 is connected to the first rotating shaft 7 through a transmission mechanism. A plurality of third guide plates 13 are provided on one side of the screening box 1, and the third guide plates 13 are fixedly connected to the first screen plate 201, the second screen plate 301 and the second guide plate 302 respectively.

[0033] This embodiment provides a vibratory screening device for grading Chinese herbal medicine slices. The feed hopper 101 is positioned above the higher end of the uppermost sieve plate 201. The slices are fed into the screening box 1 through the feed hopper 101. The slices pass through multiple screening mechanisms 2 from top to bottom, finally passing through screening mechanism 3. As the slices pass through screening mechanism 2, they fall onto the sieve plate 201, where it sieves the slices. Particles larger than the aperture of the sieve plate 201 are intercepted and roll down the sieve plate 201 onto the guide plate 3 13, where they fall into a collection box or onto a conveyor belt. Particles smaller than the aperture of the sieve plate 201 pass through the sieve plate 201 and fall onto the guide plate 202. The material plate 202 moves and falls onto the higher end of the adjacent screen plate 201 or screen plate 301. The medicinal slices falling onto screen plate 301 are screened by screen plate 301. Medicinal slices larger than the aperture size of screen plate 301 roll down along screen plate 301 to guide plate 3 13 and fall into the collection box or onto the conveyor belt. Medicinal slices smaller than the aperture size of screen plate 301 fall onto guide plate 302 and roll down along screen plate 301 to guide plate 3 13 and fall into the collection box or onto the conveyor belt. The rotation of motor 701 drives the eccentric block 10 to rotate through the transmission mechanism, causing screening mechanism 2 and screening mechanism 3 to vibrate periodically, providing power for screening.

[0034] Among them, the guide plate 1 202 has a discharge port 2021, and the discharge port 2021 has a lower end of the bottom surface of the guide plate 1 202. After the material on the guide plate 1 202 moves to the lower end, it falls through the discharge port 2021 to the higher end of the adjacent screen plate 1 201 or screen plate 2 301 below.

[0035] Among them, a fixing plate 204 is fixedly installed between the lower bottom surface of the screen plate 201 and the top surface of the guide plate 202, a fixing rod 203 is fixedly installed between the higher bottom surface of the screen plate 201 and the top surface of the guide plate 202, a fixing rod 303 is fixedly installed between the lower bottom surface of the screen plate 201 and the top surface of the guide plate 202, and a fixing plate 304 is fixedly installed between the higher end of the screen plate 201 and the guide plate 202. The fixing plate 204, the fixing rod 203, the fixing rod 303, and the fixing plate 304 are all set perpendicular to the horizontal plane.

[0036] The transmission mechanism includes a second rotating shaft 9 fixedly connected to the eccentric block 10. The second rotating shaft 9 is rotatably installed inside the screening box 1. The second rotating shaft 9 is fixedly connected to a first bevel gear 5 via a connecting shaft 501. The first bevel gear 5 and the second bevel gear 6 are meshed together. The second bevel gear 6 is fixedly connected to the outer wall of the first rotating shaft 7. Both the first bevel gear 5 and the second bevel gear 6 are located inside the outer casing 8. A motor 701 is provided above the outer casing 8 to drive the first rotating shaft 7 to rotate. The outer casing 8 is fixedly connected to the outer wall of the screening box 1. The motor 701 drives the first rotating shaft 7 to rotate, which in turn drives the first bevel gear 5 to rotate via the second bevel gear 6. Then, the connecting shaft 501 drives the second rotating shaft 9 to rotate, thereby causing the eccentric block 10 to drive the screening mechanism 2 and the second screening mechanism 3 to vibrate.

[0037] The bottom ends of both guide plate 1 202 and guide plate 2 302 are fixed with smooth rods 11, and the smooth rods 11 pass through the bottom end of the fixed seat 12 and are slidably connected to the fixed seat 12. The fixed seat 12 is fixed to the inner wall of the screening box 1, and a slider 1101 fixed to the bottom end of the smooth rod 11 is slidably provided in the fixed seat 12. A spring 1102 is fixed between the top end of the slider 1101 and the fixed seat 12, and the spring 1102 is wrapped around the smooth rod 11. The spring 1102 provides tension for screening mechanism 1 2 and screening mechanism 2 3. When the eccentric block 10 drives screening mechanism 1 2 and screening mechanism 2 3 to move vertically, the spring 1102 drives screening mechanism 1 2 and screening mechanism 2 3 to jump.

[0038] Among them, a discharge port 102 is provided on one side wall of the screening box 1, and the discharge port 102 is penetrated by the guide plate 3 13. The number of discharge ports 102 and guide plates 3 13 is the same.

[0039] Among them, the mesh size of the sieve plate 201 set from top to bottom decreases sequentially, and the mesh size of the bottom sieve plate 201 is larger than that of the sieve plate 301, so as to achieve precise separation of medicinal slices with different particle sizes.

[0040] It is understood that this utility model only requires one drive source to achieve synchronous and stable vibration of each level of screening mechanism. At the same time, the material guiding structure of the guide plate in the screening mechanism is inclined in the opposite direction to the screen plate, which can guide the material to be evenly dispersed on the surface of the screen plate.

[0041] A specific application of the operation process in this embodiment is as follows: The Chinese herbal medicine slices to be graded are fed into the screening box 1 from the feed hopper 101, falling onto the uppermost sieve plate 201. The motor 701 drives the rotating shaft 7 to rotate, which in turn drives the rotating shaft 9 and the eccentric block 10 to rotate via bevel gears 5 and 6, generating periodic vibration. Under the influence of this vibration, the slices on the sieve plate 201 are subjected to the following: finer materials smaller than the mesh size fall to the guide plate 202 and through the discharge port 2021 into the lower screening mechanism 2 or screening mechanism 3; coarser materials larger than the mesh size move along the inclined direction of the sieve plate 201 to the guide plate 13 and are finally discharged from the discharge port 102, completing the first-stage grading.

[0042] Fine material falling into the lower screening mechanism 2 continues to pass through the next layer of screen holes of screen plate 201 under vibration, and material that does not pass through continues to be transferred to the lower layer; if it reaches screening mechanism 3, it will be further screened through screen plate 301 to complete multi-level classification.
