Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical manufacturing technology, and in particular to an air separator for processing Chinese herbal medicine slices. Background Technology
[0002] In the modern processing of Chinese medicinal herbs, air separation is a crucial step in ensuring the purity of the herbs. It is widely used in scenarios such as impurity separation before processing, grading of herbs of different specifications, and cleaning of medicinal debris after processing. Whether it is root, stem, fruit, or flower and leaf herbs, after initial processing such as slicing and cutting, they often contain light impurities or substandard small particles such as mud, sand, debris, and hair. This air separator can accurately remove impurities through airflow separation, providing clean raw materials for subsequent processing and packaging, and meeting the needs of large-scale and standardized processing.
[0003] A search revealed that Chinese Publication No. CN221387502U discloses a horizontal air separator for processing Chinese herbal medicine slices with a protective structure, relating to the field of Chinese herbal medicine processing technology. The air separator includes a base plate, a support column mounted on the top of the base plate, an air separator chamber mounted on the top of the support column, a fan mounted on one side of the air separator chamber, a baffle mounted on one side of the air separator chamber, and a feeding chamber mounted on one side of the top of the air separator chamber. The feeding chamber contains a feeding mechanism, and a feeding port is mounted above the feeding chamber. By incorporating a feeding mechanism within the feeding chamber, and utilizing the interaction between the feeding plate, mounting cavity, servo motor, drive gear, transmission frame, limiting rod, and limiting sleeve of the feeding mechanism, intermittent feeding of Chinese herbal medicine slices can be achieved, resulting in better air separation performance and significantly improving the practicality of the air separator.
[0004] The patent description mentions that "by setting a feeding mechanism inside the feeding chamber, and utilizing the cooperation between the feeding plate, mounting cavity, servo motor, drive gear, transmission frame, limiting rod, and limiting sleeve of the feeding mechanism, intermittent feeding can be carried out when feeding Chinese herbal medicine pieces, making the air separator more effective in air separating Chinese herbal medicine pieces, thus improving the practicality of the air separator in use." The above content enables intermittent feeding, making the air separator more effective in air separating Chinese herbal medicine pieces. However, due to the significant differences in shape, size, and density of different varieties of herbal medicine pieces, the fixed baffle position cannot dynamically match the diverse sorting needs, resulting in a narrow range of applications and affecting the separation effect. In response to the above problems, an air separator for processing Chinese herbal medicine pieces is now proposed. Utility Model Content
[0005] The purpose of this invention is to provide an air separator for processing Chinese herbal medicine slices, which solves the problem of insufficient separation efficiency caused by the immobilization of air separators in some existing Chinese herbal medicine slice processing technologies.
[0006] To achieve the above objectives, this utility model provides an air separator for processing Chinese herbal medicine slices, including a sorting chamber. An airflow direction adjustment mechanism is provided outside the sorting chamber, and a blower is fixedly connected to the outside of the airflow direction adjustment mechanism. A feeding mechanism is provided at the top of the sorting chamber. An air separation channel adjustment mechanism is provided inside the sorting chamber, and a separation mechanism is provided at the top of the sorting chamber. The air separation channel adjustment mechanism includes a second support block, which is fixedly connected to both sides inside the sorting chamber. A second motor is fixedly connected inside the second support block, and a transmission rod is fixedly connected to the drive end of the second motor. A transmission connecting rod is rotatably connected to the outside of the transmission rod, and a transmission assembly is provided outside the transmission connecting rod. An arc-shaped groove is formed on the outside of the second support block, and a stop post is slidably connected to the outside of the arc-shaped groove.

[0021] 1. In this utility model, a flexible transmission is formed by the motor driving the transmission rod and the transmission connecting rod, enabling the sector plate to rotate stably around the limiting post. Then, the connecting block drives the baffle to slide smoothly along the arc groove. This mechanical structure design ensures the accuracy and stability of the baffle position adjustment.

The cylinder drives the transmission ring to move according to the characteristics of the medicinal slices, which in turn drives the sliding ball to slide flexibly. Then, the motion is accurately transmitted to the adjustment plate through the rotating connecting rod. The limit frame and the support block provide stable support for the transmission process, ensuring that the rotating connecting rod rotates without shaking. This allows the airflow to dynamically adjust its action mode according to the shape, size and density differences of the medicinal slices, avoiding the loss of effective medicinal slices due to excessive airflow. This improves the adaptability and separation efficiency of the equipment for different types of Chinese medicinal slices, and ensures the stability and accuracy of the air separation process.

[0031] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0032] Reference Figures 1 to 3This utility model provides an embodiment of an air separator for processing Chinese herbal medicine slices, including a sorting chamber 1. The sorting chamber 1 is the core space for separating Chinese herbal medicine slices from the airflow, providing a closed working environment for the air separation process. An airflow direction adjustment mechanism 5 is provided outside the sorting chamber 1. The airflow direction adjustment mechanism 5 is used to regulate the direction and diffusion range of the airflow entering the sorting chamber 1, so that the airflow adapts to the separation requirements of different slices. A blower 4 is fixedly connected to the outside of the airflow direction adjustment mechanism 5, and the blower 4 provides power for the air separation process. The power source generates a stable airflow and delivers it to the sorting chamber 1. The top of the sorting chamber 1 is equipped with a feeding mechanism 3, which enables uniform feeding of Chinese herbal medicine pieces and avoids material accumulation that affects the air separation effect. The interior of the sorting chamber 1 is equipped with an air separation channel adjustment mechanism 6, which adjusts the position of the baffle 62 to change the width and direction of the airflow channel in the sorting chamber 1 and optimizes the air separation path. The top of the sorting chamber 1 is equipped with a separation mechanism 2, which performs secondary separation on the airflow carrying impurities, collects impurities and purifies the air.
[0033] The air separation channel adjustment mechanism 6 includes a second support block 61, which provides installation support for the air separation channel adjustment mechanism 6 to ensure stable operation of the structure. The second support block 61 is externally fixedly connected to both sides of the inside of the sorting chamber 1. The second motor 63 is fixedly connected inside the second support block 61. The drive end of the second motor 63 is fixedly connected to a transmission rod 64. The second motor 63 is used to drive the transmission rod 64 to rotate to realize the adjustment action. The transmission rod 64 is externally rotatably connected to a transmission link 65. The transmission rod 64 transmits the power of the second motor 63 to the transmission link 65 to realize motion conversion. The transmission link 65 is externally provided with a transmission component 66. The transmission component 66 drives the baffle 62 to move through mechanical transmission to realize channel adjustment. The second support block 61 has an arc-shaped groove 67 on its outside. The baffle 62 is slidably connected to the outside of the arc-shaped groove 67. The arc-shaped groove 67 provides a sliding trajectory for the baffle 62 and restricts the movement direction of the baffle 62. The baffle 62 changes the airflow channel parameters by changing its position and guides the airflow direction.
[0034] The transmission assembly 66 includes a sector plate 662, which is internally slidably connected to the outside of the transmission link 65. A limit post 661 is rotatably connected to the inside of the sector plate 662. The transmission link 65 connects the transmission rod 64 and the sector plate 662, converting the rotational motion into the swing of the sector plate 662. The limit post 661 is externally fixedly connected to the outside of the support block 61. A connecting block 663 is externally fixedly connected to the outside of the sector plate 662. The connecting block 663 is externally fixedly connected to the outside of the stop post 62. The sector plate 662 rotates around the limit post 661 under the drive of the transmission link 65. The stop post 62 is driven to move through the connecting block 663. The limit post 661 provides a rotation fulcrum for the sector plate 662, ensuring its stable swing. The connecting block 663 connects the sector plate 662 and the stop post 62, transmitting motion to make the stop post 62 move synchronously.
[0035] Reference Figures 4 to 6 The airflow direction adjustment mechanism 5 includes a connection port 51, which is fixedly connected to the outside of the sorting chamber 1. The connection port 51 connects the blower 4 and the sorting chamber 1, providing a transmission channel for airflow. Multiple cylinders 52 are fixedly connected to the outside of the connection port 51. A transmission ring 58 is fixedly connected to the driving end of each cylinder 52. The cylinder 52 drives the transmission ring 58 to move, thereby adjusting the angle of the adjustment plate 57. A sliding ball 53 is slidably connected inside the transmission ring 58. The movement of the transmission ring 58 drives the sliding ball 53 to slide, converting the linear motion of the cylinder 52 into the rotational motion of the rotating connecting rod 55. The sliding ball 53 is fixedly connected to the outside of the rotating connecting rod 55. The internal sliding mechanism drives the rotating link 55 to rotate, thereby transmitting motion. An adjusting plate 57 is fixedly connected to the outside of the rotating link 55. The rotating link 55 connects the sliding ball 53 and the adjusting plate 57, transmitting the motion of the sliding ball 53 to the adjusting plate 57. A limit frame 56 is rotatably connected to the outside of the rotating link 55, providing rotational support for the rotating link 55 to ensure its stable rotation. A support block 54 is fixedly connected to the outside of the limit frame 56. The support block 54 is fixedly connected to the outside of the connection port 51, fixing the position of the limit frame 56 and providing an installation base for the airflow direction adjustment mechanism 5. The connection port 51 is fixedly connected to the external connection pipe of the blower 4.
[0036] The feeding mechanism 3 includes a feeding port 31, which is externally fixedly connected to the outside of the sorting chamber 1. A support frame 32 is fixedly connected inside the feeding port 31. The feeding port 31 is the inlet for Chinese herbal medicine pieces to enter the equipment and guide the material into the feeding tray 34. A motor 33 is fixedly connected inside the support frame 32. The support frame 32 fixes the position of the motor 33 and provides stable support for the feeding mechanism 3. The drive end of the motor 33 is fixedly connected to the feeding tray 34. The motor 33 drives the feeding tray 34 to rotate, so as to achieve uniform feeding. The feeding tray 34 evenly disperses the herbal medicine pieces and conveys them to the sorting chamber 1 by rotating.
[0037] The separation mechanism 2 includes an air inlet pipe 22, which is fixedly connected to the outside of the sorting chamber 1. A separation chamber 21 is fixedly connected to the outside of the air inlet pipe 22. The air inlet pipe 22 introduces the airflow carrying impurities in the sorting chamber 1 into the separation chamber 21. An air outlet 23 is fixedly connected to the top of the separation chamber 21. The air outlet 23 discharges the purified airflow to avoid dust pollution of the environment. The separation chamber 21 provides space for the secondary separation of impurities and airflow, and uses centrifugal force to separate impurities.
[0038] Working principle: The Chinese herbal medicine slices to be processed are fed into the feed port 31 and fall onto the feeding plate 34 driven by the motor 33. The support frame 32 is used to support the motor 33. As the feeding plate 34 rotates, the slices are evenly dispersed and fall continuously, laying the foundation for subsequent separation.
[0039] As the medicinal slices fall, the blower 4 starts working, and the generated airflow enters the sorting chamber 1 through the airflow direction adjustment mechanism 5. The airflow is transmitted through the connection port 51. At this time, the cylinder 52 drives the transmission ring 58 to move according to the characteristics of the medicinal slices, which drives the sliding ball 53 to slide in the transmission ring 58. The movement of the sliding ball 53 is transmitted to the adjustment plate 57 through the rotating connecting rod 55. The limit frame 56 and the support block 54 ensure that the rotating connecting rod 55 rotates stably. By changing the angle of the adjustment plate 57, the direction and diffusion range of the airflow entering the sorting chamber 1 are controlled, so that the airflow can adapt to the separation requirements of medicinal slices of different shapes.
[0040] When the airflow entering the sorting chamber 1 meets the falling medicinal slices, the motor 63 on the support block 61 drives the transmission rod 64 to rotate. The transmission rod 64 drives the transmission connecting rod 65 to slide in the middle of the sector plate 662, thereby pushing the sector plate 662 to rotate around the limiting post 661. The sector plate 662 drives the baffle post 62 to slide along the arc groove 67 through the connecting block 663, changing the position of the baffle post 62 in the sorting chamber 1, thereby adjusting the width and direction of the airflow channel, so that the medicinal slices of different densities form a layered movement under the action of the airflow.
[0041] Under the combined action of airflow and channel, the medicinal slices and impurities begin to separate. The qualified medicinal slices with higher density fall to the bottom of the sorting chamber 1 and are collected under the balance of gravity and airflow, while the impurities with lower density are carried upward by the airflow and enter the separation mechanism 2. The impurities enter the separation chamber 21 through the air inlet pipe 22 with the airflow, forming a rotating airflow in the chamber. The impurities are thrown against the chamber wall and fall down for collection under the action of centrifugal force. The purified airflow is discharged through the air outlet 23.
[0042] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
