Machining system and method for secondary positioning and continuous rotary die cutting and punching of printed matter

Abstract

The invention provides a machining system for secondary positioning and continuous rotary die cutting and punching of a printed matter. The printed matter is a coiled material. The machining system atleast comprises a coiled material unwinding device, a guide roller device, a rotary die cutting and punching device, an air pressure waste clearing device and a coiled material winding device, wherein two or more phase synchronous correcting and positioning devices are arranged at the front end of the rotary die-cutting and punching device; the phase synchronous correcting and positioning devicescomprise phase executing devices, floating devices and phase tracing devices which are sequentially arranged in the advancing direction of the coiled material, and the phase corresponding to the mounting positions of the phase tracing devices coincides with the phase corresponding to the rotary die-cutting and punching device; and a synchronous control device is further arranged, and the synchronous control device is connected with the rotary die-cutting and punching device, the phase executing devices and the phase tracing devices correspondingly. According to the machining system, the printed matter is secondarily positioned through the phase synchronous correcting and positioning devices, the precision of rotary die cutting and punching can be ensured, the machining error of the machining system is small, and the machining efficiency of the machining system is high.

Description

technical field [0001] The invention provides a processing system and processing method for circular die-cutting and punching, in particular to a processing system for circular die-cutting and punching with continuous feeding and secondary positioning correction for printed matter, which belongs to printing machinery technology field. Background technique [0002] For the secondary processing of printed matter, since the printed matter has been printed with patterns and colors in advance, when further processing (die-cutting and punching) is required for the printed matter, there is a high requirement for die-cutting accuracy, if the error If it is too large, it is easy to cut off the printed part or leave a large blank, resulting in lower quality of printed matter. At present, the die-cutting and punching of printed matter is generally carried out by flat-bed intermittent die-cutting machines. Although the processing efficiency of flat-bed die-cutting machines is low, its ...

AI Technical Summary

Problems solved by technology

However, the current rotary die-cutting machine is not suitable for secondary processing of printed matter, only for primary processing of printed matter

This is because the existing rotary die-cutting machine has the defects of inaccurate positioning, inaccurate forming, and large die-cutting error (±0.2mm). Cutting and punching processing will result in cutting off the printed part or leaving a large blank, resulting in lower quality of printed matter

[0004] Therefore, there is an urgent need in this field to provide a circular pressing and circular processing system suitable for continuous processing of die-cutting and punching of secondary printed products, so as to solve the defects of poor positioning accuracy and large processing errors of existing rotary die-cutting machines
