Description

Technical Field

[0001] The invention belongs to the technical field of quantitative subpackaging in the production of traditional Chinese medicine injections, and in particular relates to quantitative subpackaging equipment in the production of traditional Chinese medicine injections. Background Art

[0002] In the process of producing and packaging Chinese medicine injections, it is necessary to inject medicine into multiple medicine bottles at one time. During the injection process, it is difficult to ensure that the amount of medicine injected into each bottle is the same. In addition, during the packaging process of Chinese medicine injections, the discharge port is in direct contact with the medicine, and some medicine is likely to remain. If the discharge head is not detachable, these residual medicines are not easy to clean. Long-term accumulation will breed bacteria, affect the quality of the medicines, and may even cause cross-contamination between different batches of medicines, and it is not convenient to replace them when damaged.

[0003] According to the authorization publication number CN216584160U, a drug dispensing device for biopharmaceutical production is disclosed. The drug dispensing device is composed of a drug dispensing box 1, a liquid storage chamber 2 and a liquid return component. The drug liquid is first temporarily stored in a predetermined amount through the liquid storage chamber 2 of equal capacity, and the excess drug liquid is discharged through the liquid return component. Then, the drug liquid temporarily stored in the liquid storage chamber 2 is discharged into the drug bottle to be filled, thereby ensuring that the amount of drug liquid filled in each drug bottle is consistent. In actual use, the drug bottle is transported to the drug dispensing box by a conveyor belt structure. Directly below the box 1, the drive component 4 is then moved in the process, and then the second valve 11 is closed, and then the medicine liquid is transported to the medicine distribution box 1 through the liquid inlet pipe connection port 7, and it is ensured that the amount of medicine delivered is more than five times the filling amount of a single medicine bottle, and then the second valve 11 is opened, and then the excess medicine liquid is allowed to flow along the drainage groove 12, the return liquid hole 9, and the return liquid pipe 3 to the medicine liquid recovery box, and then the first valve 10 is opened, the gas supply equipment is started, and then the medicine liquid is completely pushed into the medicine bottle, and then the drive component 4 is returned to complete the filling operation.

[0004] The above patent realizes the function of quantitative medicine, but the quantitative volume of the medicine injection liquid cannot be adjusted, which is not convenient for controlling the capacity of the medicine injection liquid, and the discharge head is not convenient for disassembly and replacement when damaged, and it is not convenient for daily cleaning of the discharge port.

When the electric push rod drives the round rubber piston to push downward, the internal pressure of the medicine liquid temporary storage cylinder is greater than the external pressure. The medicine liquid is pushed out of the medicine liquid temporary storage cylinder under the action of the downward pushing pressure of the round rubber piston. A liquid level scale is provided on one side of the outer wall of the medicine liquid temporary storage cylinder to facilitate observation of the liquid level capacity, which is conducive to adjustable quantitative output of the medicine liquid. Further, a supporting groove matching the square shift block is provided on one side of the outer wall of the square shell by manually shifting the square shift block to slide toward one end of the spring. At the same time, the square shift block will also drive the abutting round rod to slide toward one end of the spring, and when the abutting round rod slides toward one end of the spring, it drives the spring to be compressed in the supporting sleeve, so that the square shift block drives the abutting round rod to disengage from the matching abutting square groove. A sealing rubber ring is provided on the outer wall of the top of the discharging abutting round tube to increase friction when abutting against the bottom of the inner cavity of the medicine liquid temporary storage cylinder, thereby improving the sealing performance.
