Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment and relates to a cutting and trimming production line for thin notebooks. Background Art

[0002] A loose-leaf notebook is a commonly used stationery item, which consists of a cover, a loose-leaf binder (or coil), and inner core papers. The biggest difference from an ordinary notebook is that a loose-leaf notebook is more flexible in use. The pages inside the loose-leaf notebook can be freely disassembled, replaced, and combined, which is convenient for sorting.

[0003] The existing processing technology for the inner core of a loose-leaf notebook is as follows: The printed papers are cut into the size of the inner core by a paper cutter, then transferred to a punching machine for punching, then transferred to a chamfering device for chamfering the four top corners of the inner core, and finally bagged and packaged. In order to improve production efficiency, wide and long papers are first printed and punched, and then the long papers are slit. In order to ensure the quality of the finished inner core notebook, the four sides of the inner core notebook are trimmed while slitting.

[0004] At present, for the trimming processing of the inner core notebook, although there are some simple semi-automatic devices, the automation degree of such devices is low. Workers need to put the four sides of the inner core notebook into the trimming machine in turn for cutting and trimming processing, and then transfer it to the next process to complete chamfering and other work after trimming, resulting in a long turnover time of the inner core notebook between each process. This processing method has a low automation degree and low production efficiency. Summary of the Utility Model
