As preferably, described flow spiral flow guiding disc is provided with stair-stepping flow spiral deflector and spiral gas channel.
As preferably, before the gas spiral guide shell is located at coating container air intake.
As preferably, the shell of coating container is spheric container body.
As preferably, be provided with the centrifugal high pressure air-introduced machine at the end of induced draught system.
As preferably, in entering the pipeline of gas spiral guide shell, high efficiency particulate air filter is provided with aerator.
Compared with prior art, the beneficial effect that this utility model is brought is: this utility model makes improvements on the basis of tradition end spray coating machine, in the pipeline before entering the gas spiral guide shell aerator is installed, air is input in the gas spiral guide shell efficiently, gas passes through gas spiral deflector effect wherein, form spiral uprising gas, this gas enters in the coating container through the spiral stream guidance dish, from gas channel, discharge and form spiral jatharapanvartanasana air-flow, granule under this air-flow effect, piller, micropill, tablet fully effectively mixes with the coating material that rotary atomizer ejects, the effect of remaining dust air inducing air-flow in the centrifugal high pressure air-introduced machine is discharged, reach available ventilation, can make coating material and granule, piller, micropill, the mixing of tablet is full and uniform and energy is dry, has higher coating quality, gained surface coatings thing is even, bright and clean, can prepare sustained-release preparation and taste masking, painted.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Shown in Fig. 1-4, as a kind of embodiment of the present utility model, this coating machine comprises roughing efficiency air filter with dry air import and the medium effeciency filter 1 that connection successively communicates, dehumidifier 2, cold and hot air door 3, heater 4, high efficiency particulate air filter 5, gas spiral guide shell 7, coating container 8, filter chamber 9, induced draught system 10, transfusion and atomization system 13 and control system 12, end at induced draught system 10 is provided with centrifugal high pressure air-introduced machine 11, in order to the gas in the filter chamber 9 is extracted out through induced draught system 10, in entering the pipeline of gas spiral guide shell 7, high efficiency particulate air filter 5 is provided with aerator 6, in order to air is sent in the gas spiral guide shell 7.On the inwall of gas spiral guide shell 7, be provided with the gas spiral deflector 71 of elevating screw shape, the gas that passes through from high efficiency particulate air filter 5 can be changed into spiral helicine uprising gas enters in the coating container 8, the shell of described coating container 8 is spheric container body 83, in coating container 8, be provided with flow spiral flow guiding disc 82 and rotary atomizer 81, described flow spiral flow guiding disc 82 is conical through stack to be arranged, and rotary atomizer 81 stretches out conical top.
Specifically, the coating material of in infusing, packing in advance, in coating container 8, pack into granule, piller, micropill, tablet with container.Described flow spiral flow guiding disc 82 is provided with stair-stepping flow spiral deflector 802 and spiral gas channel 801, several flow spiral flow guiding disc 82 stacked arrangement become the pyramidal shape of ladder, the gas that rises from gas spiral guide shell 7 enters into coating container 8 by gas channel 801, because its stair-stepping structure makes gas form in coating container 8 and circles round.Gas channel 801 can satisfy passing through of most of air quantity, be arranged in the granule, piller, micropill, tablet of coating container 8 this moment owing to the acceleration of air-flow is risen, the rotation that rotary atomizer 81 does not stop, coating material is radial court to be sprayed all around, the effect of air blast makes granule, piller, micropill, tablet highly fully to contact with coating material, reach the purpose of coating, thereby overcome adhesion of granular material coating or the serious problem of crane span structure phenomenon.Owing in the coating process, low amounts of dust can occur, therefore, can effectively the dust in the coating container 8 be sucked in the filter chamber 9 at the induced draught system 10 terminal air-introduced machines 11 that are provided with, from the pipeline of induced draught system 10, discharge again after filtering, purifying.
