Technical field
The present invention relates to the technical field of chemical industry automatic recipe maker, more particularly, to a kind of high low speed automatic blending
Device and distribution.
Background technology
Automatic recipe maker is a kind of essential equipment of the industries such as plastics, chemical industry, food, using very extensive.
In chemical products production process, due to different formulations variation relation, dosage of the same raw material in different formulations, has from several
Ten grams to tens kilograms of excursion.It is big straight in configuration and traditional automatic recipe maker its screw rod is commonly single size
Footpath screw rod, while meeting big dosage dispensing speed, can not but meet the proportioning accuracy of small dosage situation；And in configuration minor diameter
Screw rod, while meeting small dosage dispensing speed, can not but meet the proportioning accuracy of big dosage situation.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide the height that a kind of dispensing speed is fast, proportioning accuracy is high
Low speed automatic recipe maker and distribution.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of high low speed automatic recipe maker is provided, including electric control system and the confession that is connected respectively with electric control system
Expect mechanism, feed mechanism, metrological service, the feeding machanism, feed mechanism, metrological service's order coordinate；The feed mechanism
Including motor, transmission mechanism, agitating shaft, can according to the first dispensing screw rod of dosage and desired value difference automatic clutch and/or
Second dispensing screw rod, the input terminal of the transmission mechanism are connected with motor, output terminal and the first dispensing screw rod, the second dispensing spiral shell
Bar, stirring axis connection；The first dispensing screw rod is arranged in parallel with the second dispensing screw rod and opposite direction rotating, and described second matches somebody with somebody
Expect that the diameter of screw rod is more than the diameter of the first dispensing screw rod；The agitating shaft is equipped with the paddle for preventing that material is built bridge in feeding machanism
Leaf.
The high low speed automatic recipe maker of the present invention, using a power source motor, by the setting of transmission mechanism, at the same time
Realize driving agitating shaft, the first dispensing screw rod and the rotation of the second dispensing screw rod, the first dispensing screw rod is minor diameter screw rod, is realized
High accuracy charging, the second dispensing screw rod is major diameter screw rod, realizes quick dispensing；When the second dispensing screw rod engages, first matches somebody with somebody
Expect that screw rod, with identical rotating speed opposite direction rotating, realizes quick dispensing with the second dispensing screw rod；When the rotation of the second dispensing screw rod and the
When one dispensing screw rod is out of service, low speed dispensing is realized；When the second dispensing screw rod disconnects, the rotation of only the first dispensing screw rod, leads to
The rotating speed for overregulating the first dispensing screw rod realizes precision dispensing；Using a motor as power, compared to traditional design saving
Cost；In addition, the present invention has the screw rod of two kinds of sizes at the same time, the profile from tens grams to tens kilograms can be real
