Title    Structural Design and Control One-way Valve Bags Sealed Automatic Assembly Machines
Abstract
The subject completed a one-way valve bag sealing machine automatic assembly and structure of the overall program design, modular design concept, will feed into the module assembly machines and assembly modules, combined module frame body through a reliable and stable institutions. 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.
