Abstract With the unceasing progress of science and technology, packaging and printing industry is developing to the integration and intelligent, which mainly reflects the manufacturing automation of packaging and printing machinery。 The die cutting machine with a wide variety has an important role in this industry, and its automation degree is uneven。 Vertical die cutting machines are used frequently in China whose automation degree is much lower。 Three factors that low content of technology, strong labor intensity and unsafety are seriously detrimental to the development of Chinese packaging industry。

Via analyzing performance characteristics of vertical die cutting machine including its template operation track, feeding and unfeeding operating feature and its operation period, we gain the functional requirement of feeding and unfeeding device。 Based on consulting a large number of domestic and international research and reorganizing advantages and disadvantages of existing loading and unloading device, a new automatic loading and unloading device is designed in this paper, which can improve the work efficiency and labor condition of die cutting machine effectively。

Based on existing structures of automatic feeding and unfeeding device and the functional requirement of vertical die cutting machine and feeding and unfeeding device, there are several feasible plans in this paper。 Via comparing and analyzing, we choose the best plan in economy and carry on the detailed design。 According to the force analysis of typical operating position, the power of motor is worked out。 Then mainly design the drive part of automatic feeding and unfeeding device, including the drive part from motor to principal axis and the axis to the operating structures。 And this paper work out the paper feeding successively and the wide-angle rod of pendulum。

With the assistance of SOLIDWORKS Simulation, we can verify the feeding and unfeeding motion and its interference。 The analysis of control object and its control requirement is carried out in this paper and we can ascertain the control object and control signal。
