Technical Field
[0001] The utility model relates to the technical field of book production equipment, in particular to a device for rounding 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 left chamfers and the two right chamfers of the inner core book. 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. The four chamfering knives correspond to the four top corners of the inner core book. When the inner core paper stack is transported to the chamfering station, the inner core paper stack may be offset due to the inertia of the transport. If the inner core paper stack is not neatened, the quality of the inner core chamfering will be affected. Summary of the invention

[0019] The utility model will be further described below in conjunction with the accompanying drawings.
[0020] like Figure 1 , 2 As shown, a device for rounding the inner core of a loose-leaf book comprises a conveyor belt mechanism 2, a rounding mechanism 4, an aligning mechanism 3 for aligning the inner core 5 of the loose-leaf book in the longitudinal direction, and a transverse beating mechanism 1 for aligning the inner core 5 of the loose-leaf book in the transverse direction.
[0021] like Figure 3 As shown, the conveyor belt mechanism 2 includes a conveyor belt 22 and a plurality of conveying auxiliary components connected to the conveyor belt 22. The conveying auxiliary components include a positioning block 21, which is fixed on the conveyor belt 22 by clamping, and the positioning block 21 can adjust the position according to the size of the loose-leaf book core 5. Two adjacent conveying auxiliary components arranged in opposite directions on the conveyor belt 22 form a conveying station, and one conveying station conveys a loose-leaf book core 5; the positioning block 21 has a positioning plane 211, and the two positioning planes 211 of the two positioning blocks 21 of the same conveying station are arranged oppositely, and the loose-leaf book core 5 is arranged between the two positioning planes 211, and the loose-leaf book core 5 is constrained on both sides by two conveying auxiliary components, so that the conveying process is kept neat to the maximum extent.
[0022] like Figure 2 , 4As shown, the aligning mechanism 3 is arranged above the conveyor belt mechanism 2, and is used to push the loose-leaf book core 5 to the positioning plane 211 close to the rounding mechanism 4. The aligning mechanism 3 includes a paper aligner 31 arranged above the conveyor belt mechanism 2, a paper aligning cylinder 32 driving the paper aligner 31 to move forward and backward, a lifting cylinder driving the paper aligning cylinder 32 to move up and down, and a sensor sensing the loose-leaf book core 5; the paper aligning cylinder 32 and the sensor are installed on the bracket, and the lifting cylinders distributed on both sides of the conveyor belt mechanism 2 are connected to both ends of the bracket; when the sensor senses that the loose-leaf book core 5 reaches the rounding position, the conveyor belt mechanism 2 stops conveying, the lifting cylinder drives the paper aligner 31 to descend to a suitable height, and the paper aligning cylinder 32 drives the paper aligner 31 to slap the side of the loose-leaf book core 5 away from the rounding mechanism 4; after the aligning action is completed, the rounding mechanism 4 acts and rounds the two corners on the same side of the loose-leaf book core 5.
[0023] like Figure 1 As shown, before the loose-leaf book core 5 is aligned longitudinally, it needs to be aligned transversely by a transverse beating mechanism 1. The transverse beating mechanism 1 includes beating units arranged on both sides of the conveyor belt mechanism 2. The beating units include a beating plate and a driving assembly for driving the beating plate.
[0024] like Figure 1 , 2 As shown, the fillet cutting mechanism 4 includes mounting seats 41 arranged on both sides of the conveyor belt mechanism 2, a crossbeam 42 spanning above the conveyor belt mechanism 2, a cutter assembly 45 and a paper pressing assembly 46. The two ends of the crossbeam 42 are respectively connected to the mounting seats 41 on both sides, and the cutter assembly 45 and the paper pressing assembly 46 are installed on the crossbeam 42. A rack 43 is provided on the mounting seat 41, and a gear 44 is provided at the end of the crossbeam 42. The gear 44 meshes with the rack 43. A slide groove for sliding the end of the crossbeam 42 is provided on the mounting seat 41. The fillet cutting mechanism 4 can adjust the front and rear position through the movement of the crossbeam 42. The movement is more accurate through the coordination of the gear 44 and the rack 43, and the displacement of the two ends of the crossbeam 42 can be ensured to be the same. The cutter assembly 45 and the paper pressing assembly 46 are a group and fixed on the crossbeam 42 through a mounting frame. Two groups of cutter assemblies 45 and paper pressing assemblies 46 are provided on the crossbeam 42 to round the two corners on the same side of the loose-leaf book core 5. The cutter assembly 45 includes a cutter and a cutter cylinder driving the cutter to move up and down; the paper pressing assembly 46 includes a pressing block and a paper pressing cylinder driving the pressing block to move up and down; when rounding the corners, the paper pressing cylinder first drives the pressing block to move downward and press the corner of the loose-leaf book core 5, and then the cutter cylinder drives the cutter to move downward to round the corner of the loose-leaf book core 5.
[0025] Principle of the utility model: the rounding device only rounds the two corners on one side of the loose-leaf book core 5, so the loose-leaf book core 5 needs to pass through two rounding devices to round the four corners; the conveyor belt mechanism 2 positions and conveys the loose-leaf book core 5 through the conveyor belt and conveying auxiliary components. After the loose-leaf book core 5 reaches the rounding station, the conveyor belt mechanism 2 stops. At this time, the two corners on one side of the loose-leaf book core 5 correspond to the rounding mechanism 4. Before rounding, the aligning mechanism 3 is used to pat the other side of the loose-leaf book core 5 so that the loose-leaf book core 5 is aligned with the rounded side as the reference. Finally, the two corners on the same side of the loose-leaf book core 5 are rounded by the rounding mechanism 4.
