Abstract

As the demand for food diversification, personalization, automatic powder food machine applications more generally. Most of the current China-made equipment is to copy。
Simple import of imitation products, the automatic food machine for powder-depth study of key components, the basic principles, structure, movement, functional analysis, to provide a simple and reliable structure, convenient operation, high degree of automation with a wide range of food machines is necessary.
      Based on the analysis of powder food machine automatic food processes and the use of the requirements on the basis of the key components of the theoretical analysis, a practical, simple, reliable and versatile drive system, a single package for the bag to expand the size and output of long adjustable structure; for delivery of the film structure, the structure of closed traction, closed-end structure, such as cutting off key parts of the design principles, structural features, such as doing a more detailed study and design; This paper analyzes the law of the Kinematics , optimizing the structure and put forward feasible to meet the food process; a key component of a complete design method, designed to meet the market demand,Promoting innovation.
