Grain, and to be usually plurality of raw materials be mixed abrasive grains, the ratio of every part of raw material is also not quite similar.Such as：In sandblasting, very
Used many kinds of substance as abrasive material in long a period of time, it is known that inorganic abradant, as silicon carbide, aluminium oxide, silica, ceramics and
Bortz powder, still, in grinding, these inorganic abradants may be too strong with article contacts and be also possible to damage article sheet
Body, in contrast, oneself includes the synthetic resin abrasive material of polymer beads through suggested, they are soft with article contacts and are not easy
Damage article itself.
Secondly, currently, the charging of abrasive grains, which relies primarily on, first shakes feeding, again by weight sensor to material progress
It weighs, the control with realization to material inlet amount, a kind of abrasive grains mixing device as disclosed in CN206152756U, although

Process in, realize material quantitative, automatic, accurate sub-material addition be just particularly important, however, the prior art
In, raw material mostly uses extensive feed mode, it is difficult to accomplish accurately to weigh with accurate blanking, cannot accomplish weight feed and company
Continuous cycle weighs feed.In view of cost problem, the feed way that general small business's selection manually quantitatively weighs needs a large amount of
Manpower and materials operate, and labor intensity is big, due to discontinuous feed way, cannot meet the needs of product consecutive production,
Reduce product.The higher constant volume of a large amount of the degree of automation or quantitative batcher exists in the prior art, subtracts to a certain extent

Expects pipe piles with, and triggers infrared detecting device, simultaneously closes off the second motor-driven valve at once（6）With the first motor-driven valve（5）Complete first
Secondary constant volume opens simultaneously the third motor-driven valve of two expects pipes when nylon abrasive grain and alumina particle complete constant volume
（7）, nylon abrasive grain and alumina particle are discharged completely, close third motor-driven valve（7）, and the second motor-driven valve is opened, wait for the
One motor-driven valve（5）And the second material between motor-driven valve is when falling within above third motor-driven valve completely, then open the first motor-driven valve；
Seven, make grinding material of nylon abrasive grain and alumina particle in header（14）Place converges, and stirs evenly acquisition mixed material, and
Electric guard board is opened by PCL, makes to converge material and passes through batch mixer entrance（16）Into batch mixer（23）It is interior；
Eight, by spiral conveying blade（22）Mixed material is delivered to batch mixer outlet（25）；
Nine, mixed material is received, and the mass ratio of nylon abrasive grain and alumina particle is 1 in material:1；
Ten, repetitive cycling, continuous 10 constant volume mixed materials will be in each table by data record in attached drawing 3.
It is made as described below based on above-described embodiment and comparative example：
（1）The second motor-driven valve of the present invention（6）Neighbouring expects pipe diameter is less than the diameter of expects pipe near first and third motor-driven valve,
And the structure to narrow for arc, why by motor-driven valve（6）Neighbouring expects pipe is set as arc and becomes narrow structure, mainly considers
Granule materials will appear the phenomenon that " accumulation tip " when filling expects pipe, and cause practical filling effect existing not as good as expected
As, therefore by motor-driven valve（6）Neighbouring expects pipe is set as arc and becomes narrow structure, advantageously reduces because caused by filling is less than accidentally
Difference.
（2）Although being only used only in the present invention has the second motor-driven valve of excellent interception effect and third motor-driven valve can be real
Existing constant volume effect, this just seems that the first motor-driven valve is unimportant, however, the first motor-driven valve is actually indispensable, first is electronic
Valve can be effectively protected the second motor-driven valve from the extruding of particle and error caused by weighing, and enable the second motor-driven valve
Enough effective foldings, i.e. the first motor-driven valve functions only as interception function because of no constant volume effect, secondly for screw feeding
For device, wherein sealing off plate（21）And material baffle（24）Most important for the service life of conveying device, no sealing is small
It can be easy into Bearing inner, no baffle is crossed, particle can not effectively be assembled.
（3）Although being calibrated using standard pipe, when filling each time, the stack manner of particle inevitably can be by
Difference, therefore it is inevitable that error, which exists, as " people cannot step into same twice described in Ancient Greece man Heraclitus
River " is calibrated all each time it cannot be guaranteed that the particle stack manner each time in expects pipe is completely the same, and specific constant volume mode is such as
Attached drawing 2 shows, in addition by that can be obtained in the table of attached drawing 3, the final batch mixing of the present invention is complete as a result, i.e. nylon/batch mixing=50.20%
Beautiful close to theoretical value 50%, and the discrete fluctuation of the batch mixing proportioning of apparatus of the present invention is 0.004232, and device is extremely stable.
（4）When the shape of material is more regular, calibration effect is better, and device operation is more stable, such as 0.3 ~ 0.5mm
The average value of aluminium oxide is 50.18kg, deviation 0.311, and the average value of nylon is 50.599, and standard deviation is also larger
0.6746, i.e. stack manner is more difficult with standard pipe calibration, and actual mass differs bigger with theoretical value, and fluctuation is also brighter
It is aobvious.
（5）When boring particle size becomes larger, constant volume effect has not significant impact, but for irregular material,
The fluctuation of its constant volume effect is larger.
（6）The effect of comparative example can not be mentioned in the same breath with the present invention, and the operational stability of comparative example device is very poor.
More than, although having carried out illustrative explanation to the present invention by preferred embodiment, the present invention does not limit to
In this specific embodiment, change appropriate can be implemented in the scope for being recorded in protection scope of the present invention.
