Abstract
The utility model discloses a screw feeder, in particular a screw feeder for producing a raw material medicine. The screw feeder comprises a right crushing shaft, a left crushing shaft, a right screw shaft and a left screw shaft which are fixed by a supporting bed plate, wherein a hopper, a delivery pipe and a motor are connected with a half coupling; one end of the delivery pipe is provided with an end cover which is connected with a flange A and a washer C; a feed connecting pipe is arranged at the tail end of the delivery pipe; and the screw feeder also comprises an iron frame for supporting. The screw feeder has the advantages of rational mechanism, high efficiency in working and suitability for producing the raw material medicine.
Description
Technical field
The utility model relates to a kind of screw feeder, refers in particular to a kind of production of raw medicine and uses screw feeder.
Background technology
The principle of work of screw feeder is: (1) for thicker material (average diameter of particles 90 μ m), common trapezoid spiral, pressure spiral, twice relaxed helix, three-way screw feeding bar can both be realized reinforced preferably.Wherein, pressure screw feeding bar flow is little than other several kinds of screw feeding bars, is easy to realize Small Flow Control (0.1-0.6g/min); (2),, make that blanking has intermittently, the not generation of blanking phenomenon owing to common trapezoid spiral, pressure helical feed power deficiency for thinner material (average diameter of particles 40 μ m).And twice relaxed helix, three-way screw feeding bar can be realized blanking preferably.The reinforced characteristic of twice reinforced bar of relaxed helix is superior to three-way screw feeding bar, and flow less (0.4-0.1g/min); (3) for the reinforced realization of the low discharge object particle of subparticle, mainly be the contradiction between carrying capacity and the friction drag.Reinforced bar parameters such as pitch, line number, helical pitch, spiral form, lead angle are all influential to reinforced characteristic.
The having relatively high expectations of used screw feeder in the existing production of raw medicine, but often there is the irrational phenomenon of project organization in the screw feeder that uses at present, causes its work efficiency not high, influences manufacturing schedule.
Summary of the invention
The utility model purpose is to provide a kind of production of raw medicine rational in infrastructure, efficient work to use screw feeder.
The technical scheme of the utility model is: comprise by supporting seat board fixing right crushing shaft, left crushing shaft, right-hand screw axle and left-hand screw axle; Hopper; Conveying pipeline, motor links to each other with half a coupler, is provided with the end cap that links to each other with flange A, packing ring C at an end of conveying pipeline; The end that is installed in conveying pipeline is taken in blanking, also comprises the brandreth that is used to support.
Wherein, above-mentioned crushing shaft links to each other with half a coupler through gear A, gear B, gear C and gear D with screw shaft, and rolling bearing units A and rolling bearing units B are installed between the gear, is provided with seal ring A, seal ring B, packing ring A and packing ring B in the junction.
Above-mentioned seal ring A and seal ring B are the rotary lip seal circles.
Described motor is a cycloid direct connection electromagnetic adjustable speed motor.
Described blanking adapter and conveying pipeline are installed in vertical direction.
The utility model mechanism is reasonable, and efficient work is suitable for the production of bulk drug.
