New type of automatic batching loading system design

Abstract

Automatic batching system is one for all sorts of different types of materials (solid or liquid) for conveying and proportion, heating, mixing and finished product packaging of whole production process automation production line. Widely used in chemical industry, metallurgy, building materials, food industry, feed processing, etc.

This article mainly revolves the feed mills batching process is studied, including the composition of batching system, batching process, the loading system composition, the basic principle of electronic scale, etc., application of PLC (programmable Logic controller) technology, automatic batching loading system is designed and proposed mobile hopper said two-speed feeding type zero method weighing control scheme. Use of Siemens company's S7-200 programmable controller can be designed to meet the control requirements of automatic batching loading control system. And by S7-200 simulation software to verify the effectiveness of the system. Anticipated target of this design is to change the previous way of traditional ingredients system, enhances the working efficiency of the operation personnel, improving the batching accuracy of batching system, improve management level and production efficiency of industrial system, solve the problem of industrial ingredients loading, so as to realize the optimization of resource configuration, improve the industrial efficiency and economic benefits.

Dosing and loading process and precision, the author of this paper to focus on research, concluded that portable two-speed feeding hopper said type zero method weighing control scheme can meet the demand of feed mills in the ingredients.
