Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine decoction piece processing technology, and specifically discloses a cleaning sieve tube device for processing traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces are prepared medicinal materials that have undergone cleaning, cutting, and processing to produce prescription drugs that can be directly used in TCM clinical practice. Their quality directly affects clinical efficacy. Cleaning is a crucial step in the processing of TCM decoction pieces. It requires the use of sieves to remove debris, dust, impurities, and non-compliant particles from the medicinal materials, ensuring the purity and medicinal safety of the decoction pieces. The sieve, with its highly efficient sieving capacity, is the core equipment in the cleaning process, and its performance directly determines the processing quality and production efficiency of TCM decoction pieces.

[0003] However, existing sieve cylinder devices for cleaning Chinese medicinal herbs have significant shortcomings in practical applications. Traditional sieve cylinders mostly adopt a horizontal structure, relying on the continuous rotation of the cylinder to achieve material sieving. However, after sieving, this structure requires manual labor using tools to remove the herbs from the sieve cylinder, which is not only labor-intensive and inefficient but also prone to secondary contamination due to manual or tool contact. Another common design is to tilt the sieve cylinder or install a spiral guide plate inside to facilitate the discharge of herbs. However, such devices tend to have poor sieving results because the material residence time inside the sieve cylinder is too short.

[0004] Therefore, a cleaning sieve device for processing Chinese herbal medicine slices is needed to solve the above problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-5 A cleaning sieve cylinder device for processing Chinese herbal medicine slices includes a mounting box 1 and a sieve cylinder 10. A fixing frame 2 is fixedly connected to the right side of the inner wall of the mounting box 1. First bearings 3 are fixedly connected through the front and rear sides of the fixing frame 2. Steering shafts 4 are fixedly connected inside the two first bearings 3. A steering block 5 with a cavity 6 is fixedly connected between the two steering shafts 4. A drive motor 7 is installed inside the cavity 6. The output end of the drive motor 7 extends to the outside of the steering block 5 and is fixedly connected to a turntable 8. A side plate 9 is fixedly connected to the left end of the turntable 8. The sieve cylinder 10 has multiple sieve holes 11 and is fixedly connected to the left end of the side plate 9. A self-locking drive mechanism is provided on the front side of the fixing frame 2.

[0026] A guide hopper 13 with a conical inner wall is fixedly connected to the left side of the screen cylinder 10. A sealing mechanism is provided on the left side of the guide hopper 13. The sealing mechanism includes a servo electric actuator 20 installed at the left end of the mounting box 1. A movable plate 22 is provided inside the mounting box 1. The output end of the servo electric actuator 20 extends into the interior of the mounting box 1 and is fixedly connected to the movable plate 22 with a pressure sensor 21. A sealing disc 23 is provided on the right side of the movable plate 22, which abuts against the left end of the guide hopper 13. A first controller is installed at the left end of the mounting box 1 and is electrically connected to the pressure sensor 21 and the servo electric actuator 20 respectively.

[0027] In this embodiment: In the initial state, the left opening of the screen cylinder 10 faces to the left, and the sealing plate 23 is separated from the left end of the guide hopper 13;

[0028] When it is necessary to add materials, the self-locking drive mechanism drives the front steering shaft 4 to rotate 90 degrees clockwise. The steering shaft 4 drives the steering block 5, turntable 8, side plate 9 and sieve cylinder 10 to rotate 90 degrees clockwise in sync, so that the left side opening of the sieve cylinder 10 faces upward. At this time, the sieve cylinder 10 is in a vertical state. The medicinal materials are poured into the sieve cylinder 10 through the conical opening of the guide hopper 13. Then the sieve cylinder 10 rotates back to a horizontal state counterclockwise around the steering shaft 4.

[0029] Then, the first controller controls the extension of the servo electric push rod 20, pushing the moving plate 22 to the right. The moving plate 22 drives the sealing plate 23 to move to the left end of the guide hopper 13 through the steel column 24. When the sealing plate 23 abuts against the left end of the guide hopper 13, the pressure sensor 21 detects the contact pressure and transmits the signal to the first controller. The first controller controls the servo electric push rod 20 to stop moving. The pressure threshold is preset in advance to avoid overpressure damage to the medicine or parts. The servo electric push rod 20 adopts a worm gear transmission structure and uses its self-locking characteristic to maintain the current position, thereby sealing the opening on the left side of the guide hopper 13 through the sealing plate 23 to prevent the material from spilling out.

[0030] When screening is to be performed, the second controller controls the drive motor 7 to start, and the output end drives the turntable 8, side plate 9 and screen cylinder 10 to rotate at high speed. The speed is set by the second controller. Fine impurities (debris, dust) fall into the bottom of the mounting box 1 through the screen hole 11, are discharged through the rectangular discharge frame 26, and are collected through the collection container. Qualified medicinal materials remain in the screen cylinder 10 until screening is completed. In this way, the problem of poor screening effect caused by short residence time of medicinal materials in the screen cylinder 10 is avoided.

[0031] When material discharge is required, the first controller controls the servo electric actuator 20 to retract, driving the sealing disc 23 to move to the left to its initial position and separate from the guide hopper 13. Through the self-locking drive mechanism, the drive sieve cylinder 10 rotates counterclockwise 90 degrees around the steering shaft 4, so that the left opening of the sieve cylinder 10 faces downward. At the same time, the qualified medicinal materials in the sieve cylinder 10 fall into the bottom of the installation box 1 through the guide hopper 13 under the action of gravity, and are discharged into the collection container through the rectangular discharge frame 26. In this way, the medicinal materials in the sieve cylinder 10 are automatically discharged after screening, without the need for manual digging or tool assistance, which significantly reduces labor intensity and improves production efficiency, while avoiding secondary pollution caused by manual contact.

[0032] As a technical optimization of this utility model, the self-locking drive mechanism includes a drive frame 16 fixedly connected to the front end of the fixed frame 2. A worm gear 17 is rotatably connected inside the drive frame 16. A worm wheel 18 is meshed with the outer wall of the worm gear 17. A transmission shaft is fixedly connected between the worm wheel 18 and the steering shaft 4 located on the front side. A servo motor 19 with an output end fixedly connected to the worm gear 17 is installed on the outer wall of the drive frame 16. A second controller electrically connected to the servo motor 19 and the drive motor 7 is installed on the right end of the mounting box 1.

[0033] In this embodiment: the second controller controls the servo motor 19 to drive the worm gear 17 to rotate. The worm gear 17 meshes with the worm wheel 18 for transmission, and drives the front steering shaft 4 to rotate 90 degrees clockwise through the transmission shaft. The worm gear 17 and worm wheel 18 transmission has a self-locking function to ensure that the screen cylinder 10 is stably positioned at any angle and to prevent the screen cylinder 10 from shifting due to material weight or vibration. The second controller installed on the right end of the mounting box 1 controls the rotation angle of the servo motor 19 according to the preset program, and controls the speed and rotation time of the drive motor 7 as needed.

[0034] As a technical optimization of this utility model, the inner wall of the screen cylinder 10 is fixedly connected with multiple lifting plates 12 arranged in a circular array. Multiple screen holes 11 with their centers on the same horizontal line form a group, and multiple groups of screen holes 11 are staggered with multiple lifting plates 12 respectively.

[0035] In this embodiment: when the sieve cylinder 10 rotates, the lifting plates 12 arranged in a circular array lift the medicinal materials from the bottom of the sieve cylinder 10 to the height of the cylinder wall. The materials fall due to centrifugal force and gravity, and collide with the sieve holes 11 multiple times, thereby improving the screening efficiency.

[0036] As a technical optimization of this utility model, a second bearing 25 is embedded in the left end of the sealing disc 23, and a steel column 24 is fixedly connected between the inner wall of the second bearing 25 and the right end of the moving plate 22.

[0037] In this embodiment: the left end of the sealing disc 23 is embedded in the second bearing 25, and the steel column 24 passes through the inner ring of the second bearing 25 and is fixed to the right end of the moving plate 22, so that the sealing disc 23 can rotate freely around the steel column 24. When the screen cylinder 10 rotates, the sealing disc 23 rotates synchronously with the screen cylinder 10 because it abuts against the guide hopper 13. The rolling friction of the second bearing 25 is much lower than the sliding friction, avoiding the rotational resistance caused by the rigid connection between the sealing disc 23 and the moving plate 22, and ensuring that the screen cylinder 10 rotates smoothly.

[0038] As a technical optimization of this utility model, the left end of the steering block 5 is fixedly connected to the mounting ring 14, and the inner wall of the mounting ring 14 is fixedly connected to the outer wall of the turntable 8.

[0039] In this embodiment: the mounting ring 14 is fixed to the left end of the steering block 5, and the third bearing 15 provides support to the turntable 8.

[0040] As a technical optimization of this utility model, the left end of the movable plate 22 is fixedly connected with a sliding rod that passes through the mounting box 1 and is slidably connected to the mounting box 1.

[0041] In this embodiment: the sliding rod fixed at the left end of the movable plate 22 passes through the left side wall of the mounting box 1 and is slidably connected to the preset sliding groove, which restricts the movable plate 22 to move only in the horizontal direction and improves the stability of movement.

[0042] As a technical optimization of this utility model, the lower end of the mounting box 1 is connected to a rectangular material discharge frame 26.

[0043] In this embodiment, the fine impurities falling through the sieve holes 11 fall directly into the bottom of the mounting box 1 and are discharged through the rectangular discharge frame 26 connected at the lower end.

[0044] The working principle and usage process of this utility model: In the initial state, the left opening of the screen cylinder 10 faces to the left, and the sealing plate 23 is separated from the left end of the guide hopper 13;

[0045] When feeding is required, the second controller controls the servo motor 19 to drive the worm gear 17 to rotate. The worm gear 17 meshes with the worm wheel 18 for transmission. Through the transmission shaft, it drives the front steering shaft 4 to rotate 90 degrees clockwise. The steering shaft 4 drives the steering block 5, turntable 8, side plate 9 and sieve cylinder 10 to rotate 90 degrees clockwise in sync, so that the left opening of the sieve cylinder 10 faces upward. At this time, the sieve cylinder 10 is in a vertical state. The medicinal materials are poured into the sieve cylinder 10 through the conical opening of the guide hopper 13. Then, the second controller controls the servo motor 19 to rotate in the opposite direction, driving the sieve cylinder 10 to rotate back to a horizontal state counterclockwise.

[0046] Then, the first controller controls the extension of the servo electric push rod 20, pushing the moving plate 22 to the right. The moving plate 22 drives the sealing plate 23 to move to the left end of the guide hopper 13 through the steel column 24. When the sealing plate 23 abuts against the left end of the guide hopper 13, the pressure sensor 21 detects the contact pressure and transmits the signal to the first controller. The first controller controls the servo electric push rod 20 to stop moving. The pressure threshold is preset in advance to avoid overpressure damage to the medicine or parts. The servo electric push rod 20 adopts a worm gear transmission structure and uses its self-locking characteristic to maintain the current position, thereby sealing the opening on the left side of the guide hopper 13 through the sealing plate 23 to prevent the material from spilling out.

[0047] When screening is to be performed, the second controller controls the drive motor 7 to start, and the output end drives the turntable 8, side plate 9 and screen cylinder 10 to rotate at high speed. The speed is set by the second controller. The lifting plate 12 on the inner wall of the screen cylinder 10 lifts the medicinal materials to a high position as it rotates. When the material falls due to gravity, it comes into full contact with the screen holes 11. Fine impurities (debris, dust) fall into the bottom of the installation box 1 through the screen holes 11, are discharged through the rectangular discharge frame 26, and are collected by the collection container. Qualified medicinal materials remain in the screen cylinder 10 until the screening is completed. In this way, the problem of poor screening effect caused by short residence time of medicinal materials in the screen cylinder 10 is avoided.

[0048] When material discharge is required, the first controller controls the servo electric actuator 20 to retract, driving the sealing disc 23 to move to the left to its initial position and separate from the guide hopper 13. The second controller controls the servo motor 19 to start again, driving the sieve cylinder 10 to rotate 90 degrees counterclockwise, so that the left opening of the sieve cylinder 10 faces downward. At the same time, the qualified medicinal materials in the sieve cylinder 10 fall into the bottom of the installation box 1 through the guide hopper 13 under the action of gravity, and are discharged into the collection container through the rectangular discharge frame 26. In this way, the medicinal materials in the sieve cylinder 10 are automatically discharged after screening, without the need for manual digging or tool assistance, which significantly reduces labor intensity and improves production efficiency, while avoiding secondary pollution caused by manual contact.
