Problems solved by technology

However, the existing designs are uniform, and can only be packaged for powders with general fluidity, relatively uniform apparent specific gravity, and relatively regular powder particles with low viscosity. For extremely good or poor fluidity, Powders with high viscosity or irregular particles cannot be repacked. Even if some can be barely repacked, the actual loading volume is not standard, which affects product quality.

Embodiment 1

[0026] The mechanism used to improve the accuracy of medicament dispensing, including belt drive 1, motor 2, electromagnetic clutch 3, support 4, connecting rod, feeding screw 5, stirring rod 6, hopper 10, feed inlet located above the hopper 10, A pipe connected to the hopper 10 and located below the hopper 10, a valve 8 located below the pipe, and a feeding nozzle 9, the valve 8 connecting the pipe and the feeding nozzle 9 together;

[0027] The belt transmission device 1 is connected to the motor 2, the electromagnetic clutch 3 is located below the belt transmission device 1, a support 4 is connected below the electromagnetic clutch 3, a stirring rod 6 is connected below the support 4, and the support 4 and the stirring rod 6 are arranged in the hopper 10. Inside, the electromagnetic clutch 3 and the support 4 are both sleeved on the outside of the connecting rod, the connecting rod is connected to the belt transmission device 1, and the feeding screw 5 is connected below the co...

Embodiment 2

[0030] Further, the stirring rod 6 includes a vertical part at the upper part and an S-shaped part at the lower part, and the vertical part is also provided with an arc-shaped strip. The vertical part of the stirring rod 6 is provided with an arc-shaped strip, which can accelerate the strength and speed of the loose powder, so that the powder is not easy to unite.

[0031] There are a plurality of the arc-shaped bars, and a plurality of the arc-shaped bars are arranged inwardly from top to bottom along the vertical part or a plurality of the arc-shaped bars are arranged from top to bottom along the vertical part Facing the inside-facing the outside alternately. In order to enhance the loosening effect of the powder that is loose and easy to unite, multiple arc strips can be used, and the parallel arrangement can also achieve the purpose. The arrangement from the bottom of the upper road to the inner side and the outer side can make the loose area Enlarge, play a better effect.

Abstract

The invention discloses a mechanism used for improving medicament subpackaging precision. Threads on a feeding screw rod are arranged to be variable for fluid with poor fluidity, so that the fluid flows more conveniently in the flow process. The fluid mass in the unit space is enlarged, in other words, the fluid density is increased. It can be ensured that the fluid with poor fluidity has sufficient subpackaging smoothness. The whole mechanism is integrally designed, and the whole production efficiency can be improved.

Description

Technical field [0001] The invention relates to the field of pharmaceutical machinery, in particular to a mechanism for improving the accuracy of dispensing medicine. Background technique [0002] In medicine, most of the powder injection products use powder dispensers to dispense powders and powders. The powder dispensers quantitatively dispense sterile powder drugs into sterilized and dried glass bottles and seal them with a rubber stopper. [0003] Powder dispensing machines can be divided into screw dispensing machines and air flow dispensing machines according to their structure. These two dispensing machines have their own characteristics and can be used flexibly according to actual conditions. [0004] The screw filling machine uses the intermittent rotation of the screw to fill the powder into the bottle to achieve the purpose of quantitative filling. The screw packing machine has the advantages of simple structure and small loss of raw materials. The screw filling machine ...
