The specific embodiment:

Main body of the present utility model is with like product is identical at present, and it comprises pedestal and paint individuality equally, and the container individuality is realized running by motor.See Fig. 4,5, this is the container individuality 2 that the utility model is used for ccontaining Essential colour paint, and this container individuality 2 is provided with discharge equipment 3.This discharge equipment 3 comprise a valve 31 and with the driving mechanism 32 of valve 31 interlocks, promptly driving mechanism 32 drives valves 31, makes it container individual 2 and outlet 33 be connected or block.Its concrete structure is: valve 31 is a Steering valve, and its main body is cylindrical, is provided with two passages 311,312 in it.Wherein passage 312 is used for the cavity volume and outlet 33 of connection container individuality 2, promptly works as valve 31 and rotates to certain angle, and two ports of passage 312 are just in time aimed at the outlet of container individuality 2 and the outlet 33 of discharge equipment 3.Passage 311 is used for paint and refluxes.Driving mechanism 32 is a linkage, and the hinged valve 31 of one end, the other end are provided with the relay 34 by image detector 4 controls, and relay 34 is used to control driving mechanism 32 runnings.

Rotatable propeller 21 in the container individual 2 comprises motor and helical blade 210, and these helical blade 210 bottoms and motor drive helical blade 210 rotations by gear 211 transmissions by motor.When helical blade 210 rotations, it will produce certain propelling pressure downwards, make the Essential colour paint in the container individual 2 flow out.

The course of work of whole discharge equipment is: at first, the rotation under motor drives of the spiral push jack 210 in the container individual 2 is discharged the Essential colour paint in the container individual 2 simultaneously to outlet.Valve 31 has two duties: open or close.When valve 31 was in opening, the passage 312 in the valve 31 was communicated with the cavity of container individuality 2 with outlet 33, and Essential colour paint is flowed out by outlet 33 under propeller 21 promotes.When valve 31 was in closed condition, two ports of the passage 311 in the valve 31 all were communicated with the cavity of cavity volume individuality 2, and Essential colour paint is back to again by passage 311 in the cavity volume of container individuality 2 under propeller 21 promotes like this.

Relay 34 is used to control driving mechanism 32, by opening or closing of relay 34, comes by-pass valve control 31 to be in and opens or closing state.Relay 34 is then by image detector 4 its switches of control.

Propeller 21 in above-mentioned in the container individual 2 is to be used for the Essential colour paint in the container individual 2 is flowed out by outlet 33 downwards.Certainly also can adopt other modes, for example adopt the structure of piston push type.As long as when making pressure in the container individual 2 greater than outside atmospheric pressure, paint can flow out.So, can adopt pneumatic shuttle to make in the container individual 2 and keep certain air pressure.See Fig. 6, this is another embodiment of the present utility model, and it adopts pneumatic shuttle 6 to be used for the outflow of Essential colour paint; even in order to ensure Essential colour paint flow velocity; this pneumatic shuttle 6 is provided with barostat 61, with the controlled pressure size, keeps the at the uniform velocity outflow of Essential colour paint.

The image detector 4 that the utility model adopted is a on the market high precision image detector at present.Its pixel of every centimetre can reach 1024.Adopt this image detector 4 can improve accuracy of the present utility model greatly.See Fig. 7, this image detector 4 comprises a light emitted end 41 and a light source receiving terminal 42, and the outlet 33 of discharge equipment 3 is above position between light emitted end 41 and the receiving terminal 42.When image detector 4 starts, form the light net between light emitted end 41 and the light source receiving terminal 42, when being flowed out by outlet 33, paint will pass this light net.When paint passed this light net, the light net had a superimposed cross section with paint streamer 51 (or paint tear drop 52), and image detector 4 can the very accurate size of measuring this cross section.Below, with paint tear drop 52 is that example specifies its calculating principle: see Fig. 8 a, these paint tear drop 52 height are L, its any one cross section S can regard a circle as, if we are horizontally divided into the n section to this paint tear drop 52 like this, then can regard an approximate circle cylinder as for every section, every section height is respectively L1, L2, L3 ... Ln, every section cross section is respectively: S1, S2, S3 ... Sn, so we can obtain the approximate volumes of this paint tear drop 52, V=L1*S1+L2*S2+L3*S3+ ... + Ln*Sn.See Fig. 8 b, 8c, specifically in conjunction with the utility model, because the flow velocity of paint is changeless (we take measures the front, and the flow velocity that makes Essential colour paint is even), as long as we measure the area of cross-sectional sizes in different time sections, just can calculate the paint volume that passes the light net.And the width can measure in certain time paint and pass the light net by image detector 4 time, and this width can be regarded the diameter in its cross section as, so just can calculate the area in this cross section.Just feed back cross section face circle if set per t blanking time (t is enough little) image detector 4, paint tear drop 52 image detector 4 the time so and measured four area of section: s1, s2, s3, s4 altogether by the light net, time corresponding is: t1, t2, t3, t4, because the flow velocity of paint tear drop 52 is certain (being assumed to be v), then can calculate the volume V=s1*vt1+s2*vt2+s3*vt3+s4*vt4 of this tear drop 52, as long as interlude t is enough little, just can accurately calculate the size (volume of paint streamer 51 calculates identical) of flow of paint.By the calculating of control chip, after flow of paint reached predetermined numerical value, controller starting relay 34 drove driving mechanisms 32 runnings by relay 34, makes valve 31 close.
