Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and more particularly to a quantitative dispensing equipment for drug production. Background Technology

[0002] In the pharmaceutical manufacturing process, quantitative dispensing equipment is an essential key piece of equipment. It is mainly used to accurately dispense powdered, granular, or other forms of bulk drugs into preset fixed doses for subsequent packaging or formulation processing.

[0003] Existing quantitative dispensing equipment typically includes a hopper for storing materials and a dispensing mechanism located below the hopper. The materials in the hopper primarily rely on their own gravity to fall naturally down the hopper wall and enter the dispensing mechanism for quantitative dispensing.

[0004] However, many drug powders or granular materials have poor flowability or are easily affected by environmental humidity, static electricity, etc., causing them to clump, cake, or form "bridging" at the hopper outlet. When the material is blocked in the hopper, gravity alone cannot guarantee a stable and continuous downward flow. This results in the dispensing mechanism not obtaining sufficient and uniform material, directly causing inconsistent dosages, i.e., inaccurate quantification, and frequent production line interruptions, seriously affecting the efficiency and quality stability of drug production.

[0005] Therefore, this utility model proposes a quantitative dispensing device for drug production to overcome the shortcomings of the prior art. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a quantitative dispensing device for drug production, which aims to improve the problems of drug powder easily agglomerating, resulting in poor material feeding, and the cumbersome replacement of easily damaged parts of the feeding mechanism in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a quantitative dispensing equipment for drug production, comprising: a dispensing machine body, a feeding hopper, a feeding tray, a dispensing turntable; and a feeding auxiliary mechanism and a pushing mechanism.

[0008] The material feeding auxiliary mechanism includes a mounting plate, a motor support rod, a drive motor, a turntable, a transmission shaft, a transmission frame, and rubber striking heads.

The transmission shaft is fixedly connected to the turntable, the transmission frame is slidably connected to the transmission shaft, and the rubber striking heads are fixedly mounted on the transmission frame. The rubber striking heads are correspondingly positioned on the outer wall of the feeding hopper.

[0009] The feeding mechanism includes a cylinder support plate, an electric cylinder, a scraper, a chute, positioning blocks, a magnet block, a rubber pusher strip, and a positioning strip. The cylinder support plate is fixedly connected to the dispensing machine body, and the electric cylinder is fixedly mounted on the cylinder support plate. The output end of the electric cylinder is fixedly connected to the scraper. The scraper has the chute, and the scraper is reciprocally positioned above the feeding tray. The positioning blocks are fixedly connected inside the chute, and each positioning block has a magnet fixedly connected inside. The rubber pusher strip is slidably installed in the chute, and the positioning strip is fixedly connected inside the rubber pusher strip. The positioning strip has a magnet fixedly connected inside the positioning strip that attracts the magnet block.

[0010] Preferably, the material feeding auxiliary mechanism further includes a support block and a guide barrel. The support block is fixedly connected to the mounting plate, the guide barrel is fixedly connected to the support block, and the rubber striking head slides through the guide barrel.

[0011] Preferably, the bucket-shaped structure of the hopper has a downward converging tendency.

[0012] Preferably, the scraper is provided with symmetrical positioning blocks on both sides.

[0013] Preferably, the interior of the positioning block has a groove-shaped structure, and the magnet block is fixedly disposed inside the groove-shaped structure.

[0014] Preferably, the rubber pusher has a long strip structure, and the positioning strip is embedded inside the rubber pusher.

[0015] Preferably, the electric cylinder controls the reciprocating distance of the scraper by adjusting its own stroke.

[0016] Preferably, the upper surface of the dispensing turntable has multiple quantitative cavities.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting up a feeding auxiliary mechanism, which drives a rubber striking head to intermittently strike the outer wall of the feeding hopper via a drive motor, solves the problem in the prior art that materials such as drug powder are prone to clumping or bridging in the feeding hopper, resulting in poor feeding and affecting the continuity of dispensing. It achieves the effect of forcibly breaking up material clumps through vibration, ensuring smooth drug falling, and improving the stability of equipment operation and the accuracy of dispensing.

[0018] 2. This utility model solves the problems of cumbersome and time-consuming replacement process of rubber pushers as vulnerable parts in the prior art by setting a positioning block with a magnet on the scraper of the pushing mechanism and magnetically attracting it with the positioning strip inside the rubber pusher. It achieves the effect of quick disassembly and installation of rubber pushers, shortens equipment maintenance time, and improves equipment maintainability and production efficiency.
