[0024] This utility model embodiment provides a crushing device for the production of traditional Chinese medicine decoction pieces, such as... Figure 1-4 As shown, the crushing device for the production of traditional Chinese medicine decoction pieces includes: a crushing box 1; two crushing rollers 2, both of which are rotatably mounted on the crushing box 1 and mesh with each other; a feed hopper 3, which is fixedly mounted on the top of the crushing box 1; a guide plate 4, which is disposed in the crushing box 1 and located above the crushing rollers 2, and is used to evenly spread the materials required for the production of traditional Chinese medicine decoction pieces onto the crushing rollers 2; a sieve plate 5, which is slidably disposed in the crushing box 1, and allows qualified crushed materials to pass through; a vibrating sieve mechanism, which is disposed in the crushing box 1 and is used to vibrate and sieve the materials; an air sieve mechanism, which is disposed in the crushing box 1 and is used to air sieve the materials; and a guiding mechanism, which is disposed in the crushing box 1 and is used to drive the guide plate 4 to move back and forth.

[0025] In this embodiment, the crushing box 1 serves as the main structure of the entire crushing device, used to install and support other components. The crushing box 1 provides a robust and enclosed working environment, protecting the safety of operators while ensuring the stability and controllability of materials during the crushing process.

[0026] Two crushing rollers 2 are rotatably mounted on the crushing box 1 and mesh with each other to compress and crush the material. The meshing crushing rollers 2 can effectively crush the material into the required particle size, improving crushing efficiency and quality.

[0027] The feed hopper 3 is fixedly installed on the top of the crushing box 1 and is used to introduce materials into the crushing device. The feed hopper 3 simplifies the material feeding process and makes operation more convenient.

[0028] The guide plate 4 is installed in the crushing box 1, above the crushing roller 2, to evenly spread the material onto the crushing roller 2.

[0029] The sieve plate 5 is slidably disposed in the crushing chamber 1, allowing qualified crushed materials to pass through. The sieve plate 5 enables the screening of crushed materials, ensuring the quality of Chinese herbal medicine slices.

[0030] The vibrating screen mechanism is installed in the crushing box 1 and is used to vibrate and screen the material. Vibration promotes the flow of material on the screening plate 5 and improves the screening efficiency.

[0031] The air sieving mechanism is installed in the crushing chamber 1 and is used to sieve the materials. The air force blows the lighter materials that have passed the crushing to one side of the crushing chamber 1, which facilitates the sieving of the materials and further improves the quality of Chinese herbal medicine pieces.

[0032] A guiding mechanism is installed in the crushing box 1 to drive the guide plate 4 to move back and forth. The back and forth movement of the guide plate 4 achieves uniform distribution of material on the crushing roller 2, further reducing the jamming phenomenon of the crushing roller 2.

[0033] In a further preferred embodiment of this utility model, the vibrating screen mechanism includes two pairs of support grooves 6 opened on both sides of the crushing box 1. A support rod 7 is slidably installed in the support groove 6. The support rod 7 extends to one side outside the support groove 6 and is fixedly connected to the screening plate 5. A support spring 8 is sleeved on the support rod 7. The two ends of the support spring 8 are fixedly connected to the inner wall of the support groove 6 and the top enlarged side of the support rod 7, respectively. Two screening motors 9 are fixedly installed on the crushing box 1. Two cams 10 are fixedly installed on the output rod of the screening motor 9. The cams 10 are in contact with the bottom surface of the screening plate 5.

[0034] In this embodiment, support grooves 6 are formed on both sides of the crushing box 1 for sliding installation of support rods 7. The support grooves 6 provide a stable sliding track for the support rods 7, ensuring the stability and controllability of the screening plate 5 during vibration.

[0035] The support rod 7 is slidably installed in the support groove 6 and extends to one side outside the support groove 6 and is fixedly connected to the screening plate 5. As a bridge connecting the screening plate 5 and the crushing box 1, the support rod 7 not only supports the weight of the screening plate 5, but also transmits the vibration energy of the vibrating screen mechanism.

[0036] The support spring 8 is sleeved on the support rod 7, with its two ends fixedly connected to the inner wall of the support groove 6 and the top enlarged side of the support rod 7, respectively. The support spring 8 provides elastic support for the vibrating screen mechanism, allowing the screening plate 5 to produce an up-and-down bouncing effect during vibration, thereby improving screening efficiency.

[0038] Cam 10 contacts the bottom surface of the screening plate 5 and rotates along with the output rod of the screening motor 9. The rotational motion of cam 10 is converted into the up-and-down vibration of the screening plate 5, thereby achieving the screening of materials. This design not only improves screening efficiency but also ensures the uniformity and consistency of screening.

[0039] By introducing a vibrating screen mechanism, this invention further improves the screening efficiency and quality of materials by the crushing device. The coordinated use of the support groove 6, support rod 7, and support spring 8 ensures the stability and controllability of the screening plate 5 during vibration; while the introduction of the screening motor 9 and cam 10 provides a continuous and stable power source for the vibrating screen mechanism. This design not only improves the overall performance of the crushing device but also reduces the difficulty of operation.

[0040] In a further preferred embodiment of the present invention, the air screening mechanism includes an air chamber 11 opened on one side of the crushing box 1, two fans 12 are fixedly installed in the air chamber 11, and a plurality of air outlets 13 are opened on one side inner wall of the air chamber 11, the air outlets 13 being located between the crushing roller 2 and the screening plate 5.

[0041] In this embodiment, the air chamber 11 is located on one side of the crushing box 1 to accommodate and securely mount the fan 12. The air chamber 11 provides a stable working environment for the fan 12 while ensuring that the airflow is evenly directed towards the material.

This design not only improves screening efficiency but also ensures the uniformity and consistency of screening.

[0043] The air outlet 13 is located on one inner wall of the air chamber 11, between the crushing roller 2 and the screening plate 5. The air outlet 13 is a key channel for airflow to reach the material, ensuring that the airflow can accurately act on the material. At the same time, the position design of the air outlet 13 also takes into account the crushing and screening process of the material, so that the airflow can play a role after the material is crushed and before screening, further improving screening efficiency and quality.

[0044] By introducing an air-screening mechanism, this invention further improves the screening efficiency and quality of materials by the crushing device. The coordinated use of the air chamber 11, fan 12, and air outlet 13 ensures that the airflow is evenly directed towards the materials, achieving rapid and accurate screening. This design not only improves the overall performance of the crushing device but also reduces operational difficulty. Simultaneously, the synergistic effect of the air-screening mechanism and the vibrating screening mechanism makes the material screening by the crushing device more comprehensive and efficient, further ensuring the quality of the Chinese herbal medicine slices.

[0046] In this embodiment, a guide groove 14 is formed on one side of the crushing box 1 to accommodate and fix the guide rod 15. The guide groove 14 provides a stable working environment for the guiding mechanism, ensuring that the guide rod 15 and the guide block 16 can slide smoothly. This design helps to improve the stability and reliability of the guiding mechanism.

[0047] Guide rod 15 is fixedly installed in guide groove 14 to support and guide the sliding of guide block 16. As the core component of the guiding mechanism, guide rod 15 ensures that guide block 16 can slide smoothly along a predetermined trajectory. This design not only improves the accuracy of the guiding mechanism but also ensures that guide plate 4 can move back and forth accurately.

[0048] The guide block 16 is slidably mounted on the guide rod 15 and fixedly connected to one side of the guide plate 4 extending into the guide groove 14. The guide block 16 is a key component connecting the guide rod 15 and the guide plate 4, converting the sliding of the guide rod 15 into the reciprocating movement of the guide plate 4. This design not only simplifies the structure of the guiding mechanism but also improves its working efficiency.

[0049] A guide spring 17 is sleeved on the guide rod 15, with its two ends fixedly connected to the inner wall of the guide groove 14 and the guide block 16, respectively. The guide spring 17 provides elastic support for the guiding mechanism, enabling the guide block 16 to maintain a certain stability and buffering effect during sliding. This design not only improves the durability of the guiding mechanism but also ensures the smoothness and accuracy of the guide plate 4 during its back-and-forth movement. It also facilitates the reciprocating movement of the guide plate 4 by allowing it to spring back to its original position when not under external pressure.

[0050] By introducing a guiding mechanism, this invention further improves the crushing device's ability to uniformly distribute materials. The coordinated use of the guide groove 14, guide rod 15, guide block 16, and guide spring 17 ensures that the guide plate 4 can move accurately back and forth, achieving uniform distribution of materials on the crushing roller 2. This design not only improves crushing efficiency but also reduces jamming on the crushing roller 2, further ensuring the quality of Chinese herbal medicine slices. Simultaneously, the synergistic effect of the guiding mechanism with the vibrating screen mechanism and the air screen mechanism makes the crushing device's material processing more comprehensive and efficient.

[0051] In a further preferred embodiment of the present invention, a fixing rod 18 is fixedly installed on the inner wall of the crushing box 1, a toothed block 19 is rotatably installed on the fixing rod 18, and a rack 20 is fixedly installed on one side of the guide block 16, the rack 20 meshing with the toothed block 19.

[0052] In this embodiment, the fixing rod 18 is fixedly installed on the inner wall of the crushing chamber 1 to support and fix the toothed block 19. The fixing rod 18 provides a stable foundation, ensuring that the toothed block 19 can be firmly installed inside the crushing chamber 1. This design helps to improve the stability and reliability of the entire device.

[0053] The toothed block 19 is rotatably mounted on the fixed rod 18 and meshes with the rack 20 on one side of the guide block 16. This meshing relationship between the toothed block 19 and the rack 20 converts the rotational motion of the toothed block 19 into the linear sliding motion of the guide block 16. This design not only simplifies the transmission mechanism but also improves transmission efficiency. Furthermore, because the meshing of the toothed block 19 and the rack 20 is self-locking, the stability of the guide block 16 in a specific position can be ensured.

[0054] The rack 20 is fixedly mounted on one side of the guide block 16 and meshes with the toothed block 19. As a key component of the transmission mechanism, the rack 20 converts the rotational power of the toothed block 19 into the sliding motion of the guide block 16. This design not only improves transmission accuracy but also ensures that the guide block 16 can smoothly and accurately drive the guide plate 4 to move back and forth. At the same time, due to the meshing relationship between the rack 20 and the toothed block 19, precise control of the position of the guide block 16 can also be achieved.

[0055] By introducing a transmission mechanism consisting of a fixed rod 18, a toothed block 19, and a rack 20, this invention further improves the accuracy and stability of the crushing device in material processing. The meshing relationship between the toothed block 19 and the rack 20 not only simplifies the transmission mechanism but also improves transmission efficiency and precision. Simultaneously, due to the self-locking nature of this transmission mechanism, the stability of the guide block 16 in a specific position can be ensured, thereby further improving the overall performance and reliability of the crushing device.

The operation of the drive motor 21 provides stable and continuous power to drive the movement of subsequent components. This design not only improves the overall efficiency of the device but also ensures the continuity and stability of the movement.

[0058] The drive plate 22 is fixedly mounted on the output shaft of the drive motor 21 and rotates with the drive motor 21. As a key component connecting the drive motor 21 and subsequent components, the drive plate 22 can convert the rotational motion of the drive motor 21 into the specific motion of the subsequent components. This design simplifies the transmission mechanism and improves transmission efficiency.

[0059] The adjusting rod 23 is fixedly mounted on the drive plate 22 and swings as the drive plate 22 rotates. The swinging of the adjusting rod 23 allows it to contact and push the adjusting plate 24, thereby controlling the rotation angle and speed of the gear block 19. This design not only improves the flexibility of the transmission but also enables the entire device to be precisely adjusted according to actual needs.

[0060] The adjusting plate 24 is fixedly installed on one side of the toothed block 19 and is in contact with the adjusting rod 23. The adjusting plate 24 acts as a bridge connecting the toothed block 19 and the adjusting rod 23, and can convert the rotational motion of the toothed block 19 into the oscillation of the adjusting rod 23.

[0061] By introducing a transmission and adjustment mechanism consisting of a drive motor 21, a drive plate 22, an adjusting rod 23, and an adjusting plate 24, this invention further improves the flexibility and precision of the crushing device in material processing. The drive motor 21, as the power source, provides stable and continuous power to the entire transmission system. The combined use of the drive plate 22 and the adjusting rod 23 enables precise control of the rotation angle and speed of the toothed block 19, thereby allowing adjustment of the sliding position and speed of the guide block 16. This design not only improves the working efficiency of the crushing device but also allows the entire device to be precisely adjusted according to actual needs, further improving the quality of Chinese herbal medicine slices.

[0062] Meanwhile, the simple and compact structure of this transmission adjustment mechanism reduces operating difficulty and maintenance costs. Furthermore, the self-locking nature of the meshing between the toothed block 19 and the rack 20 ensures the stability of the guide block 16 in a specific position, thereby further improving the overall performance and reliability of the crushing device.

[0064] In this embodiment, the crushing motor 25 is fixedly mounted on the crushing box 1, and its output shaft is fixedly connected to the input shaft of any crushing roller 2. When the crushing motor 25 starts, it drives the crushing roller 2 connected to it to rotate.

[0065] The crushing motor 25 serves as the power source for the crushing roller 2, ensuring its stable and continuous rotation for effective material crushing. The power and speed of the crushing motor 25 can be adjusted according to actual needs, thereby achieving precise control over crushing efficiency and particle size.

[0066] An internal viewing window 26 is mounted on the crushing chamber 1, allowing operators to observe the internal crushing situation without opening the crushing chamber 1.

[0067] The internal viewing window 26 provides operators with an intuitive observation window, allowing them to monitor the material crushing status inside the crushing chamber 1 at any time, ensuring the smooth operation of the crushing process. By observing the crushing status through the internal viewing window 26, operators do not need to directly contact the crushing chamber 1 or the crushing roller 2, reducing safety risks during operation. Based on the crushing status observed through the internal viewing window 26, operators can adjust the power and speed of the crushing motor 25 in a timely manner, or replenish the material, thereby optimizing the crushing process and improving product quality.

[0068] In summary, compared with related technologies, the guide plate 4 can evenly spread the material onto the crushing roller 2 after it enters the crushing box 1, avoiding the accumulation of material in one place, which would cause greater resistance to the crushing roller 2 and lead to jamming.

[0069] The air sieve and vibrating sieve mechanisms can effectively separate qualified and unqualified crushed materials, thereby improving the processing efficiency of Chinese herbal medicine slices.

[0070] By providing stable and continuous power through the crushing motor 25, the device can precisely control the rotation speed of the crushing roller 2 and the material distribution in the crushing box 1, which significantly improves crushing efficiency and shortens the production cycle.

[0071] The internal viewing window 26 provides operators with an intuitive means of observation, enabling them to understand the material crushing situation inside the crushing box 1 at any time and make timely adjustments as needed, thereby ensuring the accuracy of the crushing process and the stability of product quality.
