Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical weighing technology, and in particular to a feeding mechanism of a pharmaceutical weighing device. Background Technology

[0002] Pharmaceutical weighing devices are core equipment in the pharmaceutical industry. The performance of their dispensing mechanisms directly affects the accuracy and efficiency of drug dispensing. In the process of drug production, powdered and granular drugs need to be dispensed with high precision to meet strict pharmacopoeia standards. As a key execution unit of the weighing device, the dispensing mechanism undertakes the core function of controlling drug flow and ensuring accurate measurement. Its technical optimization is of great significance to improving the level of drug quality control.

[0003] Currently, the industry generally adopts gravity discharge or mechanical gate structure. Gravity discharge relies on the weight of the medicine to fall through the funnel-shaped channel, and the flow rate is controlled by manually adjusting the valve opening. Mechanical gate uses a rotating baffle or slider structure, and the opening and closing are achieved by the motor driving the baffle displacement. Some high-end equipment combines weighing sensor feedback and uses a stepper motor to fine-tune the gate opening, but the core feeding unit still relies on the principle of physical blocking to achieve flow interception.

[0004] However, the above technologies have the drawback of insufficient precision in drug flow control. Gravity feeding is easily affected by the particle size and humidity of the drug, resulting in flow rate fluctuations. When the mechanical gate is closed, it is easy for drug particles to get stuck, causing poor sealing, resulting in micro-leakage or air infiltration. Especially for hygroscopic drugs, the gap when the traditional gate is closed will introduce moisture, causing the drug to become damp and clump, which directly affects the stability of the drug's active ingredients. This problem is particularly prominent in high-precision weighing scenarios and has become a key bottleneck restricting drug quality. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a feeding mechanism for a drug weighing device, which aims to improve the problem of insufficient accuracy in drug flow control.

[0008] Furthermore, a medicine delivery box is fixedly connected inside the outer shell, the outlet of the medicine delivery box is fixedly connected to the inner wall of the feeding pipe, and a feeding hopper is fixedly connected to the upper surface of the outer shell, with the outlet of the feeding hopper located inside the medicine delivery box.

[0009] Furthermore, a spring is provided on the outer wall of the feed cover, and one end of the spring is fixedly connected to the outer wall of the feed tube.

[0010] Furthermore, a connecting seat is fixedly connected to the lower surface of the medicine delivery box, and a spring is provided inside the outer shell.

[0011] Furthermore, one end of the second spring is fixedly connected to the lower surface of the connecting seat, and the other end of the second spring is fixedly connected to the upper surface of the base.

[0014] Furthermore, a hydraulic cylinder is provided inside the outer shell, a waste box is slidably connected to the inner wall of the base, and a material distribution pipe outlet is provided above the waste box.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the feeding assembly drives the connecting block through a hydraulic rod, which in turn drives the connecting rod to rotate the feeding cover, thereby opening and closing the feeding tube. During operation, the hydraulic rod extends and retracts to control the rotation angle of the feeding cover, precisely adjusting the falling rate of the medicine to avoid overfeeding or underfeeding. A spring assists in the reset of the feeding cover, ensuring a tight seal when closed and preventing medicine leakage or moisture absorption. This design simplifies the feeding process, improves weighing accuracy and operational reliability, and is suitable for high-precision medicine dispensing environments.

[0017] 2. In this utility model, the medicine delivery box and the feed hopper work together. After the medicine is added from the feed hopper, it is temporarily stored in the medicine delivery box and then evenly conveyed to the discharge pipe through the outlet. During operation, the wide opening design of the feed hopper facilitates rapid medicine addition, and the smooth internal structure of the medicine delivery box guides the smooth flow of medicine and reduces the risk of blockage. This component optimizes the medicine supply process, improves the medicine addition efficiency and system stability, and is especially suitable for continuous weighing operations.

The outlet of the feed hopper 4 is located inside the medicine delivery box 7. A spring 13 is installed on the outer wall of the discharge cover 12. One end of the spring 13 is fixedly connected to the outer wall of the discharge pipe 8, which helps the cover to quickly reset and seal. A connecting seat 14 is fixedly connected to the lower surface of the medicine delivery box 7. A spring 2 15 is installed inside the outer shell 3 to absorb vibrations during equipment operation. One end of the spring 2 15 is fixedly connected to the lower surface of the connecting seat 14, and the other end of the spring 2 15 is fixedly connected to the upper surface of the base 1. A discharge hopper 16 is fixedly connected to the inner wall of the base 1 to guide the medicine to fall smoothly. The discharge pipe 8 is located below the discharge hopper 16. Inside, a material distribution pipe 17 is slidably connected to the inner wall of the base 1.
