Description
Technical field
The invention relates to a kind of multisection type prescription metering blanking automation system of mixing, refer in particular to and a kind ofly will comprise the main material of powder, grain, liquid and the equipment that scalability raw materials such as rubber mass and trace mineral supplement carry out weighing and automatic blanking to muller.
Background technology
The fast development of science and technology drives the diversification and the sophistication of people's lives, for the quality requirements of clothing, food, lodging and transportion--basic necessities of life amusement also constantly in the refinement changes persuing.Therefore also drive the industry to the attention that becomes of healing of quality and diversified product requirement.Industrial circle is the demand that meets market; For adding multiple adjustment material (like block rubber, blowing agent, auxiliary agent, stabilization agent etc.) in the processing procedure of product or intermediate raw material; Reach satisfying of functional characteristic; But the also relative requirement that makes process operations becomes more numerous and diverse and more accurate, and in addition stricter again process data management could be satisfied the demand in market.
And the generally metering platform scale design of the making board of palpus plurality of raw materials prescription; Aspect conventional architectures, mainly be to be provided with a main pound bucket, account for the main material of total composition larger proportion in order to metering; Other is provided with a plurality of little pound bucket and little pound buckets of liquid that account for the secondary material formula of the less ratio of total composition in order to metering; And have measuring element in each pound bucket, and, establish the middle bucket of raw material and the conveying worm pipeline of similar number according to raw material number number in the little pound bucket of the metering of filling a prescription top; Make in the middle of its each corresponding raw material of conveying worm pipeline bucket and establish, bucket is gone up according to raw materials requirement characteristic difference and is provided with the dust arrester that artificial cast hopper or tool are gone into material conveyer in the middle of each raw material again; And when start; Be to connect and establish material and manage in raw material and pour in the bucket force feed into to middle bucket by going into material conveyer; In the dust arrester Chalk-dust filtering is delivered to raw material in the middle bucket of raw material; And utilize artificial cast hopper to drop in the middle bucket; The raw material of heterogeneity ratio is carried one by one (also being provided with the pound bucket that the little pound bucket of liquid is established to the metering of liquid charging stock) respectively in each self-corresponding main pound bucket and little pound bucket via the conveying worm pipeline by bucket in the middle of the raw material again, and in main pound bucket and little pound bucket, utilized measuring element to make metering pound weight one by one, then again will the interior raw materials of a plurality of little pound buckets be delivered in the master pound barrel the shared composition ratio of this raw material; Be delivered to mixer via branch to valve and do last raw material composition stirring, be delivered to again and make board running processing.
And can know that by above-mentioned How It Works the setting of the metering platform scale of this plurality of raw materials prescription must occupy than large space and height (height in about the 2nd～three buildings); So factory building that the occupation of land amount is set is big; And it is dangerous big to feed intake with a dead lift during pan feeding, can produce the empty bag of a large amount of flying dust and raw material storehouse again, and owing to need in batches the multistage pan feeding to muller on the processing procedure; Also possibly go into wrong material, product is all scrapped because of human negligence.In addition; In the pan feeding of raw material and carry to possess and have into material conveyer, conveying worm pipeline or the like; So complicated pan feeding plant equipment has not met social requirement now; Also cause the waste of cost of investment, and the traditional work flow process causes the inconvenience in the job management near all needing stockpile placed.
