DETAILED DESCRIPTION
[0029] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.
[0030] The present application embodiment discloses a paper cutting machine. Figure 1 and Figure 2 The paper cutting machine includes a cutting table 1, which has a loading position and a cutting position. The loading position is the position where the book is transported in the previous processing step, and the cutting position is the position for cutting the book. A material shifting mechanism for replacing the book on the cutting position is provided on the cutting table 1. The material shifting mechanism moves the book on the loading position to the cutting position, thereby facilitating the subsequent cutting of the book. A pressing component for fixing the book on the cutting position is provided on the cutting table 1, so that the book can remain stable during the cutting process, thereby improving the cutting effect.
[0031] Please refer to Figure 1 and Figure 2 A first electric cylinder 21 and two second electric cylinders 22 are fixedly arranged on the cutting table 1, a first cutting knife 211 is fixedly arranged on the piston rod of the first electric cylinder 21, and a second cutting knife 221 is fixedly arranged on the piston rod of the second electric cylinder 22. The two second cutting knives 221 are parallel to each other, the first cutting knife 211 and the second cutting knife 221 are perpendicular to each other, the first cutting knife 211 is used to cut the position of the book away from the spine, and the second cutting knife 221 is used to cut the position of the book on both sides of the spine. First, the first cutting knife 211 falls to cut one side of the book, and then the first cutting knife 211 is lifted, and the two second cutting knives 221 fall at the same time to cut both sides of the book. During the entire cutting process, there is no need to change the position of the book, and the cutting of three sides of the book can be completed by two cuts, which is more efficient and time-saving.
[0032] For details, please refer to Figure 3 The material transfer mechanism includes a connection part 31 arranged on both sides of the cutting table 1, a loading part 32 fixedly arranged on the connection part 31 near the loading position, a unloading part 33 fixedly arranged on the connection part 31 near the cutting position, and a driving assembly for driving the connection part 31 to reciprocate horizontally and vertically. Among them, the distance between the two loading parts 32 is always greater than the distance between the two unloading parts 33, so that after the two loading parts 32 clamp and fix the book at the loading position, when the connection part 31 moves toward the cutting position, the two unloading parts 33 can be against the book at the cutting position, so as to push the cut book away from the cutting position to the next processing procedure, speeding up the transfer of the book, so that the book enters the next processing procedure faster, which is conducive to shortening the time required for book processing.
[0033] Please refer to Figure 3The driving assembly includes a transverse electric slide rail 41 fixedly arranged on both sides of the cutting table 1, a transverse slider 42 slidably arranged on the transverse electric slide rail 41, a longitudinal electric slide rail 43 fixedly arranged on the transverse slider 42, and a longitudinal slider 44 slidably arranged on the longitudinal electric slide rail 43. The connecting part 31 and the longitudinal slider 44 are fixedly connected. The transverse electric slide rail 41 drives the transverse slider 42 to move, thereby driving the connecting part 31 to move closer or farther from each other, thereby achieving the clamping and releasing of the book. The longitudinal electric slide rail 43 drives the longitudinal slider 44 to move, thereby driving the connecting part 31 to move between the loading position and the cutting position, thereby achieving the loading and unloading of the book.
[0034] For details, please refer to Figure 4 The pressing assembly includes a third electric cylinder 23 fixedly arranged on the cutting table 1 and a pressing block 231 fixedly arranged on the piston rod of the third electric cylinder 23. A gasket 2311 is fixedly arranged on the pressing block 231. When the book is moved to the cutting position, the pressing block 231 moves downward under the drive of the third electric cylinder 23 to press the book against the cutting position. The gasket can increase the friction force, making the book more stable, and the book is not easy to move during cutting, thereby ensuring the cutting effect.
[0035] For further information, please refer to Figure 2 , Figure 3 and Figure 4 In order to prevent the cut waste from accumulating on the cutting table 1, a blanking port is opened between the loading position and the cutting position on the cutting table 1, and a sealing plate 5 is hinged at the position of the blanking port on the cutting table 1. A driving member for controlling the sealing plate 5 to open and close the blanking port is provided on the cutting table 1. Specifically, the driving member is a fourth electric cylinder 24, one end of the fourth electric cylinder 24 is hinged to the cutting table 1, and the other end of the fourth electric cylinder 24 is hinged to the sealing plate 5. When the first cutting knife 211 descends, the sealing plate 5 rotates to open the blanking port so that the cut waste can fall down. When the first cutting knife 211 rises after cutting, the sealing plate 5 rotates to close the blanking port, so that when the loading part 32 moves the book from the loading position to the cutting position, the book will not fall from the blanking port, which can ensure the smooth movement of the book.
[0036] A controller is fixedly disposed on the cutting table 1 , and the controller is electrically connected to the first electric cylinder 21 , the second electric cylinder 22 , the third electric cylinder 23 , the fourth electric cylinder 24 , the transverse electric slide rail 41 , and the longitudinal electric slide rail 43 , so as to realize process control.
[0037] The implementation principle of the embodiment of the present application is: the connection part 31 is controlled by the transverse electric slide rail 41 and the longitudinal electric slide rail 43, so that the loading part 32 moves the book to be cut from the loading position to the cutting position, and the unloading part 33 removes the cut book from the cutting position. In the process of the book moving from the loading position to the cutting position, the sealing plate 5 is in a closed state under the action of the fourth electric cylinder 24. When the first cutting knife 211 falls, the sealing plate 5 opens the blanking port, and after the first cutting knife 211 completes the cutting, the second cutting knife 221 falls, thereby completing the entire cutting process.
[0038] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
