Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of automatic Weighing subpackage dress suitable for medicine weighing subpackage
Put.
Background technology
In pharmaceutical industry or hospital internal institute during preparation, finished product needs to carry out subpackage according to specification weight.For piece
Agent or capsule formulation are general all directly to carry out with package packing machine subpackage, but for Chinese crude drug in bulk or heavy dose of external powder
Agent, granulated solid disinfecting agent, then lack the weighing equipment of correlation.For pharmaceutical factory etc., special automatization can be bought and filled
Installing is standby, but for disinfectant subpackage in hospital internal preparation or institute, manually can only claim to come manual using weight
Subpackage, wastes time and energy.And Chinese crude drug material weight in bulk is different, variable density greatly, when mineral Chinese crude drug is weighed, medicine
Impact to the scale pan, can make the weight for weighing up more than actual weight, produce error, cause damage to patient.But if with regard to this
Compensation is adjusted, when the extremely light medicines such as Retinervus Luffae Fructuss are weighed, because the change of falling impacts amount, can occur reverse mistake again
Difference, it is difficult to ensure that the medicine of various quality, medicament can be weighed accurately.Especially, when this weighing be present in it is dynamic not between
During disconnected blanking, meausring apparatus is shown to the weight up to setting, when catching device is removed, some medicines is had again and is fallen into, and causes
Weight of the actual drug weight more than setting.
The content of the invention
The technical assignment of the present invention is for above the deficiencies in the prior art, there is provided one kind weigh fast and accurately medicine from
Dynamic packaging device of weighing.
The present invention solves the technical scheme of its technical problem：A kind of medicine automatic Weighing packaging device, it is characterised in that：
Include successively from front to back putting frame, claim dress assembly and feedback assembly, also including driving means；Described frame of putting inclines to the back lower place
Tiltedly, the rear end for putting frame is provided with the first pin；Described title dress assembly include in the middle of first crossbeam, first crossbeam downside with perpendicular to
The trunnion axis connection in first crossbeam direction, forms a lever construction；First crossbeam upper surface is respectively equipped with from front to back second gear
Bar and third gear bar, wherein the region between the second pin and third gear bar is located at the rear of trunnion axis；Under first crossbeam leading portion
Side is provided with the slide rail and rider for moving towards in front and back, and rider is mutually slidably connected with described slide rail, the described driving means of rider connection；
Described feedback assembly includes weighing device, the described driving means of weighing device connection.
Compared with prior art, the present invention has beneficial effect following prominent：
1st, automatic Weighing is time saving and energy saving；
2nd, automatic error compensation, it is accurate to weigh；
3rd, simple structure, is adapted to miniaturization manufacture production.
