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
The present invention relates to field of pharmaceutical machinery, particularly, relating to the mechanism for improving medicament precision.
Background technology
Pharmaceutically, produce powder pin series products and mostly adopt powder racking machine to carry out the packing of medicinal powder powder, powder racking machine is by aseptic powder medicine quantitative separating in the glass bottle through sterilizing-drying, and covers tightly plug sealing.
Powder racking machine can be divided into screw type sub packaging machine and screw filling machine by its structural shape, and these two kinds of each have their own features of racking machine, can apply in a flexible way according to actual conditions.
Screw type sub packaging machine utilizes the intermittent rotary of screw rod medicinal powder to be loaded in bottle the object reaching quantitative separating.It is simple that screw type sub packaging machine has structure, the advantages such as material loss is little.Screw type sub packaging machine mainly plays packing function, point loading screw in packing head can by medicinal powder pulvis by the opening of powder falling head bottom quantitative be added in glass bottle, therefore the architectural feature of screw type sub packaging machine has very large impact for packing medicinal powder.But existing design is all unified, can only general for flowing power, apparent gravity is more homogeneous, and the less powder of powder particle comparison rule viscosity carries out packing, for flowing power spy, the comparatively large or particle fitfull powder of the good or special difference of flowing power, viscosity can not carry out packing, even if what have can packing reluctantly, but actual loading amount is suddenly big or suddenly small nonstandard, affects product design.
For this problem, the present invention makes following improvement.
Summary of the invention
Technical matters to be solved by this invention is to provide the mechanism for improving medicament precision, the thread size of feed screw is arranged to the screw thread changed by this device, make fluid in flow process, more be convenient to flowing, increase the quality of unit space inner fluid, namely fluid density is added, the fluid making flowing power poor can ensure enough packing fluencies, also the shape of screw rod is arranged to combination that is conical and cylinder in addition and makes poor fluidity, hygroscopic property is strong, sticking powder, be unlikely to form granule and bonding phenomenon, and make its apparent gravity homogeneity reach maximization in extremely short moment, this is for poor fluidity, hygroscopic property is strong, the maxim that sticking powder reaches best packing density is very favorable, also just expand the comformability to powder simultaneously, it is pyramid type by screw design, it is stronger than the screw rod of prismatic to the various effects of powder, the apparent gravity of fluid is more homogeneous, its effect is better, more can realize loading amount precision.
