ABSTRACT
This graduation design is the design of the variable speed packaged goods from plastic conveyor system.The first design on the conveyor belt system and dresser system made a simple description, and then analysis of goods from the plastic bags detailed calculation of variable speed transmission system, force analysis and selection principles, after a detailed calculation and stress analysis, on the basis of the design principle and selective principle to select the appropriate hardware to the overall design, and then to the chosen of the conveyor belt and checking calculation of main components of dresser, finally choose to control part of the system hardware to complete the goods since the plastic bags variable speed transmission design of the system design.Conveyor belt is mainly composed of the following several parts, belt, roller, shaft coupling and motor, frame, tension device, and lead back to the device, in the design of the plastic device, can choose center around cylindrical and square column.The graduation design combining mechanical aspects, control, complete the automatic production line of packaged goods from plastic conveyor system design.
Key words: conveying system;Packaged goods;Control system;Dresser
