Design of an automatic weighing check system for small material feed

Small material is an important part in feed production, and it is one of the keys to guarantee product quality. Nowadays, small materials are putting into small batches artificially in many feed enterprises, and the small materials are weighing mannually before putting. In order to improve the automation of the weighing and putting process of small materials, this study designs an automatic weighing check system for small materials. The system is composed of Arduino electronic development platform equipped with weighing sensor, liquid crystal display module (LCD), and relay module. The results show that the relative error of the weighing check measure is less than 0.2%, and it demonstrates that the system has realized the precise control of the weighing check of small materials, which is beneficial to reduce the work intensity of workers, and improve the automation degree of the feed production industry.
