The work aims to solve the existing problems of the carton forming machine such as the decentralization of molding and sticking process, inability to adapt to the production of multi-size carton boxes, and low production efficiency. Based on the TRIZ theory and targeted analysis on the existing technical problems, the technical feature parameters were extracted, and the contradictory pairs were formed. The invention principles were achieved by querying the conflict matrix. After the invention principles available were screened and the innovative design was made, the invention principles were specialized to form the practical application scheme of shaping machinery for carton forming machine. The innovative design scheme of shaping machinery to complete the molding and sticking at the same station based on the organic coupling of molding module and glue-spraying component and able to quickly adjust the tooling to suit various specifications of carton boxes was obtained. The shaping machinery for carton forming machine designed herein not only achieves the centralization of molding and sticking process and simplifies the production process, but also meets the requirements of multi-size carton boxes and improve the equipment flexibility.
