[0002] Traditional Chinese medicine decoction pieces refer to medicines that are made under the guidance of traditional Chinese medicine theory through traditional processes such as cleaning, cutting, and processing. They have specific shapes, specifications, and processing standards and can be directly used in the clinical prescription of traditional Chinese medicine or in the production of prepared Chinese medicines. During the processing and transportation of decoction pieces, fine particles, dust, and other debris are easily generated due to physical actions such as friction and collision. If these debris are mixed into the finished product, it will seriously affect the quality of the product.
[0003] Currently, existing Chinese herbal medicine decoction piece packaging equipment only has basic packaging functions and lacks a screening device for debris.

A connecting pipe 9 connected to the top of the sieving box 10 is fixed on one side of the slice box 8. An inclined sieving plate 11 is provided inside the sieving box 10 for sieving slices. A lifting pipe 503 is set below the weighing hopper 5. A weighing sensor 6 is provided on the outer wall of the weighing hopper 5 and is installed in the mounting groove opened in the horizontal plate 601.
[0028] This embodiment provides an automatic weighing device for packaging Chinese herbal medicine slices. The conveyor 1 is used to transport the dispensing bottles 3. The top of the screening box 10 is connected to a feeding hopper. The slices are fed into the screening box 10 through the feeding hopper and screened by the screening plate 11. The debris falls through the mesh of the screening plate 11 (the mesh diameter of the screening plate is ≤3mm). The slices fall along the screening plate 11 into the connecting pipe 9 and enter the screening box 10 through the connecting pipe 9. The slices in the screening box 10 are sent to the weighing hopper 5. The weighing sensor 6 weighs the weighing hopper 5 and monitors the weight of the slices in the weighing hopper 5 in real time. The weighing hopper 5 can move vertically to adjust the final discharge height of the slices, adapting to dispensing bottles 3 of different heights.
[0029] The bottom end of the screening plate 11 is fixedly equipped with a vibration motor 17, the inner wall of the screening box 10 is fixedly equipped with a fixed shell 15, and a spring 14 is provided inside the fixed shell 15. A sliding plate 13 is provided above the spring 14, and a smoothing rod 12 is fixedly provided at the top end of the sliding plate 13. The smoothing rod 12 passes through the top end of the fixed shell 15 and is fixedly connected to the bottom surface of the screening plate 11. The vibration motor 17 drives the screening plate 11 to vibrate, thereby realizing the rapid screening of the medicinal slices. The smoothing rod 12 is set vertically, and the two ends of the spring 14 are fixedly connected to the smoothing rod 12 and the fixed shell 15 respectively.
[0030] The lower end of the screening plate 11 is fixed with a guide plate 1101, and the guide plate 1101 is located inside the connecting pipe 9. The guide plate 1101 is inclined and is used to guide the medicinal slices into the connecting pipe 9.
[0031] The conveyor 1 is equipped with a gantry frame 4 at its top. The horizontal plate 601 is fixedly connected to the inner wall of the gantry frame 4. The herbal medicine box 8 is fixedly connected to the top of the gantry frame 4 via a fixed column 802. The bottom of the herbal medicine box 8 is connected to a discharge pipe 801, which extends through the top of the gantry frame 4. An electromagnetic valve is installed on the discharge pipe 801 to control its opening and closing. The bottom of the discharge pipe 801 is located inside the weighing hopper 5. After the electromagnetic valve of the discharge pipe 801 is opened, the herbal medicine falls into the weighing hopper 5 through the discharge pipe 801. A controller is fixedly installed on one side of the gantry frame 4. The controller is used to preset the target weight value.
[0032] The bottom end of the weighing hopper 5 is connected to a discharge pipe 501, and a corrugated pipe 502 is connected between the discharge pipe 501 and the lifting pipe 503. An electromagnetic valve is installed on the discharge pipe 501, and the corrugated pipe 502 expands and contracts during the lifting process of the lifting pipe 503.
[0033] The discharge pipe 501 has a fixed plate 5011 fixed on its outer wall, and the fixed plate 5011 has an electric push rod 7 fixed on it. The output end of the electric push rod 7 is fixedly connected to the fixed plate 5031 fixed on the outer wall of the lifting pipe 503. The electric push rod 7 drives the fixed plate 5031 to move vertically, thereby realizing the lifting of the lifting pipe 503.
[0034] The screening box 10 has a through groove 1001 at the lower end of its outer wall. The through groove 1001 is slidably connected to the collection drawer 16, which is located below the screening plate 11. Debris passing through the holes of the screening plate 11 falls into the collection drawer 16, which is convenient for regular cleaning and prevents debris from accumulating in the screening box 10, thus ensuring the cleanliness of the inside of the screening box 10.
[0035] Understandably, this invention can remove debris from the medicinal slices and control the discharge height of the medicinal slices to prevent the discharge port from being too far from the dispensing bottle 3, which would cause the medicinal slices to spill out.
[0036] A specific application of the operation process of this embodiment is as follows: the medicinal slices are put into the medicinal slice box 8 through the feeding hopper, the vibration motor 17 is started, the sieve plate 11 vibrates, the medicinal slices fall onto the sieve plate 11, the qualified medicinal slices move to the lower end along the inclined direction of the sieve plate 11, fall into the connecting pipe 9 through the guide plate 1101, and then enter the medicinal slice box 8. The debris falls into the collection drawer 16 through the through hole of the sieve plate 11.
[0037] After the solenoid valve of discharge pipe 2 801 is opened, the medicinal slices enter the weighing hopper 5 through discharge pipe 2 801. The weight of the medicinal slices in the weighing hopper 5 is monitored in real time by the weighing sensor 6. When the preset value is reached, the solenoid valve of discharge pipe 2 801 is closed and the solenoid valve of discharge pipe 1 501 is opened. The medicinal slices enter the dispensing bottle 3 through discharge pipe 1 501, lifting pipe 503 and lifting pipe 503. The controller is used to control the opening and closing of discharge pipe 1 501 and discharge pipe 2 801.
[0038] Before opening the solenoid valve of the discharge pipe 501, the user needs to adjust the height of the lifting pipe 503 according to the height of the dispensing bottle 3. During adjustment, the electric push rod 7 is driven, and the electric push rod 7 drives the lifting pipe 503 to rise and fall through the fixing plate 5031.
