Background technology
Along with the fast development of pharmaceutical sector, the demand of medicine constantly increases, and various pharmaceutical equipment arises at the historic moment, as batch mixer, tablet press machine, conveyer etc.Tablet is one of modal formulation of medicine, and tablet is the Formulation of suppressing after medicine and auxiliary material Homogeneous phase mixing.Because tablet tool has the following advantages: the first, transport, store and carry, apply all more convenient; The second, the dimensionally stable of product, dosage is accurate, and cost and price are all lower.Therefore, the range of application of tablet is also more and more extensive, is also necessary to the research of method for preparing tablet thereof and first relevant device.At present, tablet is prepared from by tablet press machine usually, and tablet press machine generally all comprises feed hopper and preforming device.
Same tablet press machine can be used for suppressing different tablets, tablet press machine has the drug residue of amount of powder shape at feed hopper inwall in the process of film-making, the powder medicine remained in order to avoid last compressing tablet causes the harmful effect of mixed medicine to compressing tablet next time, generally all will carry out cleaning to feed hopper after compression, the clean of feed hopper of existing tablet press machine comparatively bothers; Existing tablet press machine is inconvenient to the derivation operation of tablet after film-making.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of tablet press machine modified node method, to overcome the derivation operation inconvenience of existing tablet press machine to tablet, the clean comparatively troublesome problem of feed hopper.
The present invention's adopted technical scheme that solves the problem is: a kind of tablet press machine modified node method, comprise fixed mount, fixed mount upper end is provided with feed hopper, fixed mount is provided with mould, mould is provided with nib, lower punch die is provided with in nib, the lower end of lower punch die is hinged with lower punch die drive rod I, lower punch die drive rod II, the side of mould is provided with gathering-device, gathering-device is connected with mould by guide groove, guide groove and mould seamlessly transit, described fixed mount is provided with the upper trimming die coordinated with lower punch die, upper trimming die is equipped with upper trimming die drive rod, the bottom of feed hopper is provided with the conveying flexible pipe coordinated with mould, the feed end outer wall of described feed hopper is at least provided with 2 fixed blocks, the connecting rod II that connecting rod I and fixed block upper end that Slave Block is arranged by its one end are arranged is hinged, the other end of Slave Block is provided with shower nozzle, the water spray end of shower nozzle coordinates with the sidewall of feed hopper, shower nozzle is provided with water inlet pipe, water inlet pipe is provided with valve I, water inlet pipe is connected with air inlet lines, air inlet lines is provided with valve II, described water inlet pipe is provided with pressurizing valve between air inlet lines and shower nozzle, described valve I, valve II, pressurizing valve is controlled by the controller being arranged on feed hopper outer wall.Existing tablet press machine needs extra on mould, arrange the tablet that a thrust unit will make release mould after compression, troublesome poeration and be not easy to the derivation of tablet, existing feed arrangement is all generally adopt by feed end to the diminishing structure of discharge end internal diameter, when cleaning feed arrangement, because the bore of the discharge end of feed arrangement is less, be not easy to cleaning, cause in cleaning process, operate more troublesome problem, the driving of lower punch die drive rod I of the present invention, lower punch die drive rod II, upper trimming die drive rod all has controller I control, the height that lower punch die drive rod II stretches out, higher than lower punch die drive rod I, forms inclined-plane when making lower punch die protrude from nib, the laminating parallel with the sidewall of feed hopper of the initial state of Slave Block of the present invention, Slave Block can rotate, the folder of Slave Block and feed hopper inwall lower end is increased gradually, maximum angle is 90 °, the rotation of Slave Block drives the rotation of shower nozzle, operation principle of the present invention: the former medicine of powder enters in nib by feed hopper through conveying flexible pipe, the gauge tap controlling each input of powder stock is provided with in feed hopper, when the former medicine of powder enters in nib, powder compaction is become tablet by upper trimming die punch die cooperation under the driving of upper trimming die drive rod is rained, then upper trimming die drive rod drives upper trimming die homing, lower punch die drive rod I, lower punch die is ejected nib by lower punch die drive rod II again, lower punch die drive rod I stops extending, lower punch die drive rod II continues to extend, until tablet is ejected lower punch die by the inclined-plane making lower punch die be formed, the tablet ejected collects gathering-device by guide groove, because the end of guide groove and mould seamlessly transits, the tablet ejecting lower punch die can import in guide groove smoothly, improve the speed that tablet is derived, the present invention is by the hinged lower punch die drive rod I in the bottom of lower punch die, lower punch die drive rod II, and the height that under controlling, punch die drive rod II stretches out is higher than lower punch die drive rod I, the derivation that tablet is convenient on inclined-plane is formed when making lower punch die protrude from nib, guide groove and mould seamlessly transit, and improve the speed that tablet is derived, avoid tablet to be blocked in the end of mould, the cleaning process of feed hopper is: first control Open valve I by controller, pressurizing valve, rinse water is sprayed by shower nozzle after pressurization, the sidewall of feed hopper is cleaned, Slave Block is rotated in cleaning process, thus the angle that change shower nozzle coordinates with feed hopper inwall, the different parts of feed hopper inwall is cleaned, after washing, closed by controller and open valve I, Open valve II makes air carry out drying and processing by shower nozzle ejection to feed hopper inwall, keep the dried and clean of feed hopper inwall, the present invention cleans feed hopper inwall automatically, simple to operation, so, instant invention overcomes the derivation operation inconvenience of existing tablet press machine to tablet, the clean comparatively troublesome problem of feed hopper.
Further, feed hopper is fixed on fixed mount upper end by clamping device.Feed hopper can firmly be fixed on fixed mount by the setting of clamping device, improves the stability that feed hopper is installed.
Further, detachable being arranged on fixed mount of clamping device.Be convenient to change clamping device.
Further, the water inlet pipe between pressurizing valve and shower nozzle is set to straight tube.The resistance of straight tube is little compared with bend pipe, avoids pressure when reducing rinse water, air arrival shower nozzle to reduce, and then reduces the dynamics of cleaning.
Further, feed hopper adopts hard aluminium alloy to make.Hard aluminium alloy is prior art material, has the advantage that quality is light, hardness is large, reduces its quality while guaranteeing the hardness of feed hopper, is convenient to mobile.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by hinged lower punch die drive rod I, lower punch die drive rod II in the bottom of lower punch die, and the height that under controlling, punch die drive rod II stretches out is higher than lower punch die drive rod I, forms the derivation that tablet is convenient on inclined-plane when making lower punch die protrude from nib; Guide groove and mould seamlessly transit, and improve the speed that tablet is derived, avoid tablet to be blocked in the end of mould.
2, the present invention is by arranging rotating shower nozzle, and this nozzle connecting is connected to water inlet pipe and air inlet lines, realizes the automatic washing to feed hopper inwall and auto-drying, simple to operation, avoids the troublesome problem of feed hopper inner wall washing.
