Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to an automatic bagging device for the inner core of a loose-leaf book. Background Art

[0002] A loose-leaf book is a commonly used stationery product, which consists of a cover, a binder, and inner core paper. The biggest difference from an ordinary notepad is that a loose-leaf book is more flexible to use, and the pages inside the loose-leaf book can be disassembled, replaced, and combined at will, making it easy to organize. In existing inner core production lines, the main step is to round the corners of the inner core paper stack. For example, a loose-leaf book inner core production line with Chinese patent publication number CN219564567U includes a paper feeding device, a printing device, a slitting device, a page counting device, a stacking conveying device, a punching device, a book dividing device, a book counting device, a transverse conveying device, a chamfering device, and a book collecting device, which are sequentially arranged along the conveying direction; when the counting stacking device has stacked 5 times, the 50 sheets of paper and a cover are stacked together and conveyed by the transverse conveyor. The device is transported forward, and the distance between two adjacent inner core books is quickly pulled apart, and they are sent to the rear chamfering mechanism and the front chamfering mechanism in turn for chamfering; the chamfering device includes a front chamfering mechanism and a rear chamfering mechanism, which are arranged at intervals along the transport direction, and are respectively used to process the two chamfers on the left side and the two chamfers on the right side of the inner core book, and the front chamfering mechanism and the rear chamfering mechanism each include two chamfering knives and a driving mechanism three for driving the chamfering knives to rise and fall, and the four chamfering knives correspond to the four top corners of the inner core book. After the production of the inner core of the loose-leaf book is completed, it is generally necessary to manually bag and package it before it can be shipped out of the factory. The main step of manual bagging is to open the bag mouth, and then the inner core of the loose-leaf book can be smoothly inserted. The manual bagging operation is time-consuming and labor-intensive, and the existing technology lacks the step of automatic bagging. Summary of the invention
