Multi-stage formula metering and feeding automatic mixing system

The invention relates to a multi-stage formula metering and feeding automatic mixing system, in particular to a method for weighing and automatically feeding the adjusting raw materials such as the main raw materials including the powder, the granule and the liquid, and the rubber additive and the trace additive to the mixing machine. The device is the first to invent the application.

According to the rapid development of science and technology, the diversification and refinement of people's lives are promoted, and the quality requirements for the food, clothing, housing and entertainment are constantly improving. Therefore, it also drives the industry to pay more attention to the quality and diversified product requirements. In order to meet the needs of the market, the industry will add a variety of adjustment materials (such as rubber blocks, foaming agents, additives, stabilizers, etc.) to the process of products or intermediate materials to meet the functional characteristics, but also To make the requirements of process operations more complicated and more precise, and to be more rigorous process data management, in order to meet the needs of the market.

In general, in the traditional architecture, a main pound bucket is used to measure the main raw material, which is a large proportion of the total composition, and a plurality of materials are used for metering. Smaller barrels and small liquid barrels with a smaller proportion of the secondary ingredients, and metering elements under each barrel, and above the formula metering small barrels, the same number of raw materials are set according to the number of raw materials. Middle bucket and spiral The conveyor pipeline is arranged such that each spiral conveyor pipeline is corresponding to a raw material intermediate bucket, and then a manual feeding hopper or a dust collector with a feeding conveyor is arranged on the intermediate barrel of each raw material according to different raw material demand characteristics; When the operation is started, the material feeding pipe is connected to the material feeding pipe, and the raw material is poured into the barrel and sent to the middle barrel. The dust is filtered by the dust collector to transport the raw material into the middle barrel of the raw material, and is put into the middle barrel by using a manual feeding hopper. Then, the raw material intermediate barrels are respectively transported into the corresponding main pound barrels and small pound barrels respectively through the screw conveyor pipelines (the liquid small barrels are also provided for the measurement of the liquid raw materials). In the main pound bucket and the small pound bucket, the proportion of the raw material in the main pound bucket and the small pound bucket is measured by the measuring component, and then the raw materials in the plurality of small pound buckets are transported into the main pound bucket. It is sent to the mixer through the split valve for the final material component to be stirred, and then sent to the production machine for processing.

According to the above-mentioned operation method, the setting of the metering scale of the plurality of raw material formulas requires a large space and a height (about the height of the second to third floors), so the setting of the factory covers a large amount, and when the materials are fed, Manual handling and feeding is dangerous, and a large amount of flying dust and raw material empty bag stacks will be generated. Because the process needs to be fed into the mixing machine in batches, it may also be mistaken due to human negligence, so that all products are scrapped. In addition, in the feeding and conveying of raw materials, there must be a feeding conveyor, a screw conveyor pipeline, etc. Such complicated feeding machinery equipment has not met the requirements of today's society, and also causes waste of investment costs, and the traditional operation process It is necessary to place the raw material piles nearby to cause inconvenience in operation management.
