Description
Technical field
The present invention relates to a kind of high efficiency, constant volume abrasive grains mixing device more particularly to a kind of constant volume mixing devices, and
Its hybrid technique.Background technology
As production and development and photoelectricity, the sensor and material technology of science and technology are showing improvement or progress day by day, handset touch panel is given birth in people
Application in work is gradually extensive.Touch screen, which states clearly in production process, has a procedure for grinding, and grinding is processed as fragile material
A kind of middle very important method, plays irreplaceable role.Handset touch panel glass grinding polishing is to out-of-flatness
Glass surface is processed, the more bright and clean surface with smooth;Either glassware blank is ground, with
Reach required shape, size requirement and lower surface roughness.Attrition process at present generally uses abrasive grains, and
Abrasive grains are usually that plurality of raw materials is mixed, and the ratio of every part of raw material is also not quite similar.Such as：In sandblasting, very long by one
Section the time in used many kinds of substance as abrasive material, it is known that inorganic abradant, such as silicon carbide, aluminium oxide, silica, ceramics and Buddha's warrior attendant
Mountain flour, still, in grinding, these inorganic abradants may be too strong with article contacts and be also possible to damage article itself, phase
Than under, oneself includes the synthetic resin abrasive material of polymer beads through suggested, their soft with article contacts and not easy damageds
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, to realize control to material inlet amount, a kind of high efficiency as disclosed in CN206152756U, constant volume abrasive grains are mixed
Device is expected, although the inlet amount of material can be intuitively learnt very much by increasing weight sensor before expects pipe, due to object
The continuous addition of material so that whole device has apparent vibrations（Particle declines the vibrations that will also result in weight sensor）, most
Cause the addition of inlet amount not accurate eventually.Theoretically, Weight sensor assembly is needed to be in plateau, it is more accurate to survey
Value.But it to make the discharge bucket on weighing sensor stop shaking completely, to wait for for a long time, so in reality
When being weighed using this weighing sensor, in order to improve weighing efficiency, as long as the severity that general discharge bucket does not shake, reads
Data.It is this attended school when shaking access according to the case where will certainly cause to weigh when error, and since general feeding is all
Batch weighing so the error that every batch of weighs adds up and can become larger, therefore, weighed by above-mentioned weighing sensor
Feed weight error is very big.In addition, the sensor is fragile, failure, influence to weigh.
As above-mentioned, abrasive grains are usually that plurality of raw materials is mixed, and the ratio of every part of raw material is also not quite similar, and different
The ratio of material generates apparent influence to sandblasting effect again, therefore quantitatively mixes different materials, i.e., in abrasive material hybrid particles
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
The light workload of operating personnel, but this kind of batch charger complicated integral structure, maintenance cost and maintenance cost are higher, at some
It is difficult to carry out in medium-sized and small enterprises, poor practicability.

It is made as described below based on above-described embodiment and comparative example：
（1）During our company manufactures similar mixing device, when using unidirectional spiral batch mixing conveyer, when batch mixing is a variety of
When, final batch mixing amount is excessive, and material conveying is caused often to deliver at full capacity, tends to occur the disconnected phenomenon of axis, therefore, the present invention changes
It is conveyed with bidirectional screw, double outlets receive material, and bearing load is small, efficient.
（2）The second motor-driven valve of the present invention（6）Neighbouring expects pipe diameter is less than expects pipe near first and third motor-driven valve
Diameter, 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
The phenomenon that will appear " accumulation tip " when filling expects pipe in view of granule materials, and cause practical filling effect not as good as pre-
The phenomenon that phase, therefore by motor-driven valve（6）Neighbouring expects pipe is set as arc and becomes narrow structure, advantageously reduces and draws because filling is less than
The error risen.
（3）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.
（4）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.
（5）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.
（6）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.
（7）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.
