Firstly, one-way valve for sealing plastic bags automatic assembly machine demonstration program modules were obtained institutions preliminary two-dimensional schematic. Then the various agencies operating mechanism were analyzed to obtain more reliable and detailed data samples for the design provides a good theoretical basis. Then use Digital Prototyping technology initially established a one-way valve bag sealing three-dimensional model of automatic assembly machines, and key components of the finite element check and optimize the design. Finally finished with the power consumption monitoring, motor start-stop and brake parts detection control circuit design. The assembly machine novel structure, compact, functional, reliable, easy to operate, on aggregate, nesting, assembly and output functions in one-way valve in a plastic bag sealed automatic assembly machines in the field will have a wide range of applications prospects.
