The pasteboard supply is one of the bottlenecks for carton packaging machine. To meet the demand of pasteboard supply for carton packaging machine to achieve the production of 80 boxes per minute, this study provided a solution combined with vertical and horizontal conveying methods. The vertical conveying technology was relatively mature and widely applied. In order to improve the speed of horizontal conveying, we puts forward a resolution combined with the short-distance horizontal pasteboard conveying mechanism and the double roller conveying mechanism so as to analyze the working and structure principle of all assembly units. Meanwhile, the rationality and practicality of this resolution were discussed and the speedy conveying was also achieved.
