Abstract
本发明关于一种高效包衣机的改进设计。本发明所涉的具有特殊结构滚筒的包衣机仍包括有主机、热风机、排风机及喷雾装置、主机包括机壳、包衣滚筒、搅拌器、电机、减变速机构、调速机构、传动链，喷雾装置中的喷枪置于包衣滚筒中，包衣滚筒圆周相对排风、热风口处设有直径大于1.5mm通风孔的网板，其特征在于包衣滚筒网板里侧固定设有孔径在0.4至1mm通风孔的内网板。具有上述滚筒结构特点的本发明仅在普通的包衣机基础上进行结构调整，就能包衣加工目前为止各种规格的药丸。特别是解决了小颗粒(直径小于1.0mm)的药丸包衣加工问题，扩大了普通包衣机的应用范围。
The invention relates to an improved design of a high-efficiency coating machine. The coating machine with the drum of special structure involved in the present invention still includes main engine, hot air blower, exhaust fan and spraying device, and main engine comprises casing, coating drum, agitator, motor, deceleration and variable speed mechanism, speed regulating mechanism, transmission Chain, the spray gun in the spray device is placed in the coating drum, the circumference of the coating drum is relatively exhausted, and the hot air outlet is provided with a mesh plate with a diameter greater than 1.5mm. It is characterized in that the inside of the coating drum mesh plate is fixed with Inner stencil with ventilation holes with a hole diameter of 0.4 to 1mm. The present invention with the above-mentioned drum structure features can coat and process pills of various specifications so far only by adjusting the structure on the basis of a common coating machine. In particular, it solves the problem of pellet coating processing of small particles (diameter less than 1.0 mm), and expands the application range of ordinary coating machines.
Description
Technical field: the present invention is about a kind of improvement design of high-efficiency coating machine.
Background technology: existing coating machine is made up of main frame, hot-air blower, exhaust blower, sprayer unit (system), main frame comprises casing, coating cylinder, agitator, subtracts compositions such as gear, speed adjusting gear and motor, its operation principle is done continuous complex track motion referring to shown in Figure 1 by the tablet sheet stamen of coating in the coating cylinder of coating main frame sealing.The coating medium by the peristaltic pump supercharging in the sprayer unit, by spray gun or dropper, automatically is sprayed at sheet stamen surface after batching.Meanwhile, under negative pressure state, by hot-air blower supply with through 100,000 grades filter and the hot blasts of heating from cylinder bottom take away by exhaust blower and after dedusting the clean hot-air of discharging make the coating medium that is sprayed at sheet stamen surface obtain fast, dry uniformly, thereby on sheet stamen surface firm, fine and close, smooth, the slick surface film of formation one deck fast.Its coating cylinder of the coating machine of this structure requires to be made to bear the rotational stiffness requirement by heavy wall sheet material relatively, the common ventilation aperture that is provided with, generally can only be more than φ 2mm, also promptly can only carry out the coating operation to tablet greater than φ 2mm, and the development of medicine at present towards slow release medicine and controlled release prescription to development, above-mentioned two medicines all are to manufacture with pilule about φ 1mm or small particles form, common both at home and abroad at present coating machine all can not carry out coating processing to above-mentioned short grained tablet, for solving granule coating problem, abroad process with a kind of boiling one-step palletizing coating machine system, adopt the gas shock tablet to make it to suspend simultaneously with directly the tablet spraying (spilling) of coating medium to suspending, yet this equipment mechanism complexity, operation is had relatively high expectations, cost of manufacture makes domestic pharmaceutical factory be difficult to bear far above the ordinary coating machine.
Summary of the invention: the present invention's purpose is only to improve the coating roller frame on common coating machine basis, makes it can process large and small granule medicament simultaneously.
The coating machine with special construction cylinder that the present invention is related still includes main frame, hot-air blower, exhaust blower and sprayer unit, main frame comprises casing, coating cylinder, agitator, motor, subtracts gear, speed adjusting gear, driving-chain, spray gun in the sprayer unit places the coating cylinder, the relative air draft of coating roll circumference, hot-air mouth place are provided with the web plate of diameter greater than the 1.5mm air vent, it is characterized in that coating cylinder web plate inboard is fixed with the interior web plate of aperture at 0.4mm to 1mm air vent.
The present invention with above-mentioned roller frame characteristics only carries out structural adjustment and just can process the pill of all size so far by coating on common coating machine basis.Particularly solve the pill coating processing problems of granule (diameter is less than 1mm), enlarged the range of application of ordinary coating machine.
Description of drawings: further illustrate the present invention below in conjunction with description of drawings, provide most preferred embodiment simultaneously:
Fig. 1 is a coating machine fundamental diagram of the present invention;
Fig. 2 is an embodiment of the invention structure cutaway view;
Fig. 3 is Fig. 2 A portion enlarged drawing.
Wherein: 1, exhaust duct; 2, warm-air pipe; 3, interior web plate; 4, coating cylinder web plate; 5, spray gun; 6, moving runner; 7, coating cylinder 8, casing; 9, agitator; 10, motor; 11, cleaning disc; 12, driving member; 13, drum door.
The specific embodiment:
As shown in the figure, the operation principle of coating machine as previously mentioned, motor 10 drives coating cylinder 7 by drive 6 and driving member 12 and rotates, the relative exhaust duct of coating cylinder 7 circumference 1 and 2 mouthfuls of places of warm-air pipe are provided with diameter generally greater than the web plate 4 of 1.5mm air vent, and coating cylinder web plate 4 inboards are fixed with the aperture at 0.4 to 1mm interior web plate 3, interior comparatively speaking web plate 3 processes for thin plate, comparatively ideal aperture is about 0.8mm, wherein, air vent on the interior web plate 3 preferably is set as tapered hole, its aperture big towards coating cylinder web plate 4, beneficial to blockage resisting like this, interior web plate 3 relative coating cylinder web plates 4 also are set as tubular, its limit, two ends is fixed on coating cylinder 7 not on the wallboard with air vent, and make interior web plate 3 have spacing and help ventilation operation with coating cylinder web plate, in the space that web plate 3 and coating cylinder 7 did not constitute with the wallboard of air vent in spray gun 5 in the sprayer unit still was in agitator 9, the pill medicament is after drum door 13 feeds intake, because coating processing at 0.8mm, also can be carried out to the particulate pill of 0.8mm diameter in interior web plate 3 air vent apertures.
