Abstract
In this paper,its mainly about the detailed design, calculation, checking&selection of the Automatic toothpaste machine.First, it analyzes the Functional requirements of the Automatic toothpaste of small household appliances. It researched the System Structure and Function of the Automatic toothpaste machine,the way to select comachine.Understanding the working principle,Basic structure, System components&Function of the same type oponents&the Realization of the systerm . Final, design the special Automatic toothpaste machine
Automatic toothpaste machine is a simple product of mechatronics,it includes infrared technology,SCM technology,relay,motor technology and so on.Through the control of infrared sensors,trigger the motor’s working, then control the etrusion volume of the toothpaste through the trip of the motor.And this is the main technical route of the Domestic-automatic toothpaste machine.
The design mainly about structure desgin, assembly, material selection,control system design,selection of motor&the standard parts.In this paper,there have detailed explanations about the structure, assembly, parts map, and the control system circuit diagram& SCM procedures of the Automatic toothpaste machine.
