Description

Technical Field

[0001] The present application belongs to the technical field of quantitative medicine dispensing, and relates to a quantitative medicine dispensing mechanism with adjustable volume. Background Art

[0002] In the production of industrial explosives and the preparation of military blasting equipment, precise quantitative filling technology is a core link in ensuring blasting effectiveness and operational safety. Traditional charge-dispensing processes generally have the following technical defects: Early mechanical charge-dispensing devices mostly used fixed-volume charge troughs, achieving quantitative measurement through a rigid metering cavity. This structure cannot adapt to the dynamic adjustment requirements of the charge quantity in different application scenarios. Although the spiral-propelled charge-dispensing mechanism achieves continuous feeding, it is prone to positioning offset and adjustment errors due to vibration during filling. In addition, frictional static electricity is easily generated between the screw and the cavity, resulting in explosive residue. Residues can easily cause cross-contamination during continuous operation and pose a risk of spontaneous combustion and explosion.

[0035] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0036] This embodiment discloses a quantitative medicine dispensing mechanism with adjustable volume, such as Figure 1-Figure 7 Shown, including:

[0039] The medicine dispensing assembly 4 is provided on the movable baffle 3. The medicine dispensing assembly 4 includes a metering plate 41 with a through medicine groove 42. A metering block 45 is slidably connected to the interior of the medicine groove 42. The metering block 45 is used to adjust the volume of the medicine groove 42.

[0040] The flow dividing assembly 5 is provided on the quantitative plate 41 and driven by the driving assembly 2. The flow dividing assembly 5 has an opening corresponding to the medicine groove 42. A triangular flow dividing device 51 is provided in the opening of the flow dividing assembly 5.

[0041] The feeding assembly 7 is compressed by a spring 162 , and the feeding assembly 7 includes a feed hopper 71 . The spring 162 is arranged inside the spring pressure plate 16 of the support assembly 1 .

[0042] It should be noted that by adjusting the position of the metering block 41 relative to the medicine trough 42, the drug capacity of the medicine trough 42 can be adjusted. After the drug is diverted from the inside of the feed hopper 71 through the diverter 51 of the diverter assembly 5, it falls into the medicine trough 42 of the metering plate 41, wherein the opening separated into two outlets by the diverter 51 corresponds one-to-one with the medicine trough 42 to ensure that the drug falls into the medicine trough 42, and then the driving assembly 2 pulls the diverter assembly 5 to move to scrape off excess drug. At this time, the movable baffle 3 can be driven by the driving assembly 2 to move so that the opening 31 of the movable baffle 3 is at the bottom of the medicine trough 42 to release the drug, so that the drug is quantitatively discharged through the drug outlet 141 in the amount set by the drug dispensing assembly 4, wherein the spring 162 can play the role of pressing the diverter assembly 5, the drug dispensing assembly 4 and the movable baffle 3 to ensure the accuracy of the drug capacity inside the medicine trough 42 when the drug is scraped off by the diverter assembly 5.

[0047] It should be noted that the slider 222 is slidably mounted on the outside of the second joint 221 through the slide groove 223. At the same time, the slider 222 is connected to the diversion component 5. Therefore, the diversion component 5 can move in the vertical direction relative to the second joint 221. At the same time, the second joint 221 can pull the diversion component 5 to move in the horizontal direction.

[0048] On this basis, when replacing a medicine dispensing component 4 of a different height, the diverter component 5, the movable pressure plate 6 and the feeding component 7 can adapt to the height of the medicine dispensing component 4 and adjust their positions under the action of the spring 162 to maintain the compressed state.
