The cutting device includes a first driving motor 4 fixedly installed on the lower side of the top plate 3, a first connecting plate 5 fixedly connected to the output end of the first driving motor 4, a first cutting knife 7 fixedly connected to one end of the lower side of the first connecting plate 5, an adjusting device arranged on the lower side of the first connecting plate 5 for adjusting the left and right cutting of the book, and a pressing device arranged inside the first connecting plate 5 for pressing different types of books.

[0026] Among them, the left and right sides of the first connecting plate 5 are provided with limit components for limiting the first connecting plate 5, the limit components include rings 6 fixedly connected to the left and right sides of the first connecting plate 5, the inner walls of the rings 6 are slidably sleeved on the outer walls of the columns 2, the adjusting device includes two support plates 8 fixedly connected to the lower side of the first connecting plate 5, a second drive motor 9 fixedly installed at one end of one of the support plates 8, a threaded rod 10 fixedly connected to the output end of the second drive motor 9, two threaded blocks 11 threadedly connected to the outside of the threaded rod 10 and a second cutting knife 12 bolted to the opposite surfaces of the two threaded blocks 11, the upper side of the threaded block 11 is slidably connected in the limit groove, the second cutting knife 12 is fixedly connected to the threaded block 11 by two bolts, and the threaded rod 10 is a bidirectional threaded rod.

[0027] It should be noted that the first connecting plate 5 is driven up and down by the first driving motor 4 while the rings 6 on both sides slide in the column 2 to improve stability during movement. The threaded block 11 and the second cutting knife 12 are fixed and disassembled by bolts, which facilitates the replacement of the second cutting knife 12 at a later time.

[0028] See also Figure 1-2 In this embodiment, the pressing device includes two moving rods 13 slidably sleeved inside the first connecting plate 5, a spring 14 fixedly sleeved on the outer wall of the lower side of the moving rod 13, a second connecting plate 15 fixedly connected to the lower side of the moving rod 13, a rotating shaft 16 rotatably sleeved inside the upper side of the second connecting plate 15, a gear 18 fixedly sleeved on the outer wall of the lower side of the rotating shaft 16, a spur plate 19 meshingly connected to the front and rear side ends of the gear 18, and a movable pressing plate 17 integrally arranged on the side of the spur plate 19 away from the gear 18.

[0029] Among them, the upper side of the spring 14 is fixedly connected to the lower surface of the first connecting plate 5, and a limiting groove matching the upper side of the threaded block 11 is provided on the lower surface of the first connecting plate 5. The upper side of the rotating shaft 16 passes through the second connecting plate 15 and extends to the outside. A sliding groove 20 matching the upper side of the movable pressure plate 17 is provided on the lower surface of the second connecting plate 15. The upper side of the movable pressure plate 17 is slidably connected in the sliding groove 20. The upper side of the movable pressure plate 17 is slidably connected in the sliding groove 20. A baffle is integrally connected to the surface of one side of the spur tooth plate 19.

[0030] It should be noted that when the movable pressure plate 17 on the lower side of the second connecting plate 15 presses on the surface of the book, the spring 14 compresses itself and cooperates with the sliding of the moving rod 13 to make the movable pressure plate 17 squeeze the book more firmly. After the first drive motor 4 returns to its original position, the spring 14 rebounds and can restore the moving rod 13 to its original position.

[0031] The working principle of the above embodiment is:

[0032] The book is placed on the lower surface of the second connecting plate 15. The gear 18 connected to the rotating shaft 16 is meshed with the spur plate 19 according to the different book body shapes. The movable pressing plate 17 connected to the spur plate 19 is synchronously moved in a reverse or relative straight line on the lower surface of the second connecting plate 15 to adjust the spacing between the two movable pressing plates 17 to a position where the horizontal length of the book matches, which is convenient for pressing books of different sizes. At the same time, the second driving motor 9 can use the threaded rod 10 to drive and adjust the two threaded blocks 11 to move relative or separately on the outside of the threaded rod 10, which is convenient for cutting different positions according to needs. After the first driving motor 4 pushes the first connecting plate 5 downward, the movable pressing plate 17 is firstly attached to the surface of the book and squeezed and fixed. With the continuous force generated by the first driving motor 4, the upper side of the second connecting plate 15 slides upward through the moving rod 13 to compress the spring 14 and fit the book more closely. Then the first cutting knife 7 and the second cutting knife 12 cut the three sides of the book. After cutting, the first driving motor 4 drives the whole body away from the book in the reverse direction to complete the cutting needs.
