[0002] A booklet slitting device is a device used to automatically cut printed materials such as books, magazines, and albums. This device is commonly used in printing plants, binderies, and copy shops to improve production efficiency and ensure accurate cutting. A booklet slitting device typically includes the following main components and functions:

[0003] (1) Paper feeding system: It is used to feed the books to be cut into the slitting device. It usually adopts automatic paper feeding to improve production efficiency.

[0004] (2) Alignment system: ensures that the booklet is positioned accurately during the cutting process to avoid deviation or misalignment.

[0005] (3) Slitting knife: This is the core component of the booklet slitting device, used to cut the booklet into single pages or multiple pages. An automatic tool adjustment system is usually used to ensure cutting accuracy.

[0006] (4) Control system: used to control the operation of the entire book slitting device, including setting parameters such as cutting size, speed, and quantity.

[0007] By using the booklet slitting device, users can quickly and accurately cut large quantities of books or printed materials into the required size, improving production efficiency and reducing the error rate of manual operation.

[0041] Principle and operation process

[0042] After opening the device, the book to be cut is placed on the main platform 2 near the push plate 5, and the book is ensured to be located between the two side limiting columns 6. The electric cylinder 66 is started, and the electric cylinder 66 drives the side limiting column seat 64 to move towards the center of the rotating arm 62. At this time, the rotating arm 62 will follow the rotation, and the rotation of the rotating arm 62 will drive the connecting rod 63 on the other side to pull the limiting column seat 64 to move towards the center of the rotating arm 62, realizing the opposite movement of the two side limiting columns 6 and clamping the book to be cut. After clamping is completed, the length of the book cutting is set on the controller, and the servo motor 51 will determine the working time of the cycle according to the length. After the servo motor 51 is started, the ball screw 52 is rotated, and the push plate sliding seat 53 will drive the push plate 5 to move towards the cutting knife 3. After moving a certain distance, the servo motor 51 stops working. By stepping on the foot switch 44, the hydraulic machine 43 is started, and the top block 42 is driven to move upwards. The two levers 41 connected to the top block 42 move upwards, and the other end connected to the pressing plate 4 moves downwards, thereby driving the pressing plate 4 to move downwards to press the book. The counterweight 45 can make the pressing plate 4 quickly rise under the action of gravity after the foot switch 44 is released. After the pressing plate 4 presses the book, two cutting knife switches 22 are pressed at the same time, and the speed reducer 32 starts to work. Through the two connecting rods 31, the cutting knife 3 is driven to move downwards, and the cutting is completed. The above steps can be repeated to realize continuous cutting.
