A kind of fully-automatic capsule filling machine
[technical field]
What the present invention relates to is a kind of medicine packaging machinery, and what be specifically related to is a kind of improvement invention of fully-automatic capsule filling machine.
[background technology]
Fully-automatic capsule filling machine is a kind of medicine packaging machinery, a kind of with in powdery, graininess or the micropill, western drug is filled to the full-automatic stowage unit in the capsule, existing fully-automatic capsule filling machine comprises capsule subpackage turntable, drive mechanism, Programmable Logic Controller, described capsule subpackage turntable is provided with a plurality of stations, is respectively equipped with feeding device, medicated powder filling metering device, capsule tightening device, drawing mechanism, mold cleaning device at corresponding station.The capsule subpackage turntable of capsule filler can be realized intermittent running under the driving of drive mechanism, make be distributed in the packing turntable on, lower module carries out corresponding action under action of cam, finally finish the task of capsulae vacuus powder charge, existing capsule subpackage turntable, its upper module is fixed on the rotating disk, lower module is fixed on the guide pillar and not only does the oscilaltion reciprocating motion but also do parallel flexible reciprocating motion, be installed on like this on the case in the rotating disk outside and must have the elongated hole that can hold the guide pillar motion, because such elongated hole can't seal fully, cause medicated powder to enter the turntable inner chamber from guide pillar, form the pollution of turntable inner part, service life of a machine is reduced.The powder-scraper of existing capsule filler medicated powder filling metering device is not owing to be to adopt to inlay the into staircase structural model of dividing plate, gap between its top and the dividing plate bottom is the open type gap, so the bar passage communicates with the intra-annular chamber of Sheng powder, the filling bar is being done when working up and down, be easy to the medicated powder of spill-over in containing the powder ring is brought into the gap between powder-scraper and the dividing plate and entered lower module, thereby form medicated powder loading amount inaccurate in capsule.The mold cleaning device of capsule filler is positioned at last station of capsule filler packing turntable, the nib of module up and down that both will be in this station is cleaned out, so that next station (is initial station, the station of module nib about capsulae vacuus is sent into by feeding device) capsulae vacuus is admitted to module nib up and down smoothly, existing capsule filler mold cleaning device just includes only a suction powder box vacuum of being located at the upper module top and inhales the powder parts, the suction powder box is fixed on the workbench of capsule filler by the powder absorbing pipe of its lower end, be connected with the air draught interface, though this suction powder box can be absorbed the part interior residual medicated powder of module nib up and down, but can not absorb some may glue the residual medicated powder in jail relatively, cause capsulae vacuus can not finely enter up and down in the module nib, the capsular probability that goes up is reduced.The feeding device of existing capsule filler is located at initial station, generally only establishes a row, so its production capacity is lower.Existing capsule filler can not accurate counting to the quantity of finished capsule product.
[summary of the invention]
In view of the problem that present known technology exists, the technical problem to be solved in the present invention be to provide a kind of capsule subpackage turntable good airproof performance, medicated powder loading amount accurately, probability height on the capsule, production capacity is strong and fully-automatic capsule filling machine with capsule tally function.
For solving the problems of the technologies described above, the present invention takes following technical scheme to finish:
