[0023] The actuator includes a synchronous wheel 14 rotatably connected to the outer walls of the two fixed frames 10, and the outer walls of the two synchronous wheels 14 are cooperated with the synchronous belt 15, and the synchronous belt 15 is located between the two slide bars 11. A servo motor 16 is fixedly installed on the outer wall of one of the fixed frames 10 away from the synchronous wheel 14. The end of the output shaft of the servo motor 16 passes through the fixed frame 10 and is fixedly connected to the synchronous wheel 14. The outer wall of the moving block 12 is fixedly connected to a fixed plate 17, and the fixed plate 17 is fixedly installed on the outer wall of the synchronous belt 15 by two bolts 18. The outer wall of the cutting table 1 is also equipped with a feeding mechanism for automatically feeding cardboard.

[0024] The feeding mechanism includes a driving roller 3 and a pressure roller 8. The driving roller 3 is rotatably connected to the inner wall of the cutting table 1. Two mounting frames 6 are fixedly connected to the top outer wall of the cutting table 1. Slide blocks 7 are slidably connected to the inner walls of the two mounting frames 6. The rotating shafts at both ends of the pressure roller 8 are rotatably connected to the inner walls of the two slide blocks 7, and the pressure roller 8 is located directly above the driving roller 3.

[0025] A spring 9 is installed inside the mounting frame 6 , the bottom end of the spring 9 is fixedly connected to the top outer wall of the slider 7 , and the top end of the spring 9 is fixedly connected to the top inner wall of the mounting frame 6 .

[0026] A stepper motor 5 is fixedly mounted on one outer wall of the cutting table 1 via a bracket 4 , and the output shaft end of the stepper motor 5 passes through the cutting table 1 and is fixedly connected to one end of the driving roller 3 .

[0027] The feeding mechanism further comprises a conveyor belt 2 installed on the inner wall of the cutting table 1 , and the conveyor belt 2 is located behind the driving roller 3 and the pressure roller 8 .

[0028] The outer wall of the bottom of the cutting table 1 is fixedly connected with a plurality of bolts 18 , and the plurality of bolts 18 are distributed at the four corners of the bottom of the cutting table 1 .

[0029] The implementation principle of a cardboard edge cutting device in an embodiment of the present application is as follows: in actual use, the working states of the stepper motor 5 and the servo motor 16 can be controlled by an external control unit (not shown in the figure), so as to control the feeding mechanism and the actuator to cooperate in cutting the cardboard, specifically: the cardboard is placed on the conveyor belt 2 and the conveyor belt 2 is started, and the conveyor belt 2 conveys the cardboard to between the pressure roller 8 and the driving roller 3. It is worth noting that the slider 7 can be pushed upward, and the slider 7 drives the pressure roller 8 to move upward so that the distance between the pressure roller 8 and the driving roller 3 is sufficient for the cardboard to pass through. After the cardboard passes through, the force applied to the slider 7 is withdrawn, and the slider 7 drives the pressure roller 8 to press the cardboard under the elastic force of the spring 9 to limit the cardboard, and then the stepper motor 5 is controlled to start, and the output shaft of the stepper motor 5 drives the driving roller 3 to rotate, through the cooperation between the driving roller 3 and the pressure roller 8 The rotation drives the cardboard to continue to move forward until the edge of the cardboard moves to the front end of the cutting table 1. At this time, the servo motor 16 can be controlled to start, and the output shaft of the servo motor 16 drives the synchronous wheel 14 to rotate, and the two synchronous wheels 14 rotate in conjunction with the synchronous belt 15. During this process, the synchronous belt 15 will drive the fixed plate 17 to move, and the fixed plate 17 will drive the moving block 12 to slide on the outer wall of the slide bar 11, and the moving block 12 will drive the blade 13 to move. When the blade of the blade 13 contacts the side wall of the cardboard, the cardboard is cut. After cutting is completed, the servo motor 16 drives the synchronous wheel 14 to rotate in the opposite direction, and then drives the blade 13 to reset through the synchronous belt 15. In this way, when the feeding mechanism conveys the cardboard to the front end of the cutting table 1, the actuator drives the blade 13 to move and cut the cardboard. This cycle is repeated to achieve automatic cutting of the cardboard.
