AI Technical Summary
The production speed of the existing loose-leaf production line does not match the front and rear channels, resulting in low production speed and low efficiency of the entire production line.
A thin-book cutting and diversion production line is designed, including front and rear-path production lines. The front-path production line includes paper feeding, printing, slitting, page counting and dividing devices. The rear-path production line includes edge trimming, flying, punching and rounding devices. The inner core book is alternately sent to two rear-path production lines through the diversion device to ensure that the speed of the front and rear production lines remains unchanged.
While ensuring that the front and rear production lines remain unchanged, the production speed and efficiency of the entire production line are significantly improved.

Description
Technical Field
[0001] The utility model belongs to the technical field of printing equipment and relates to a cutting and shunting 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 disassembled, replaced, and combined at will, 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 the inner core is transferred to a chamfering device for chamfering the four top corners of the inner core into rounded corners, and finally bagging packaging is carried out.
[0004] In order to improve production efficiency, wide and long papers are used to carry out printing work first, then the long papers are slit, cut into several notebooks, and then the subsequent trimming, punching, and chamfering processes are carried out one by one. Since this series of subsequent processes need to be carried out one by one, the production speed is relatively slow, while the front-end printing and slitting processes process multiple notebooks at a time, and the production speed is relatively fast, resulting in a mismatch between the production speeds of the front and back parts. Only the processing speed of the front end can be reduced, thus causing the problem of low production speed and low production efficiency of the entire production line. Summary of the Utility Model
