[0023] See also Figure 1-Figure 4 The utility model provides the following technical solutions: A chamfering machine with a self-feeding structure for book production, comprising a workbench 1, two limiting side plates 2 are installed on the top of the workbench 1, a fixing frame 3 is connected to the top of the two limiting side plates 2, two first cylinders 4 are installed on the top of the fixing frame 3, a baffle 5 is arranged at one end of the two limiting side plates 2, a fixing plate 6 is arranged on one side of the baffle 5, and a mounting frame 7 is connected to the top of the fixing plate 6;

[0024] A second cylinder 8 is installed at one end of the mounting frame 7, a chamfering blade 9 is installed at the output end of the second cylinder 8, a mounting groove 10 is provided inside the workbench 1, a motor 11 is installed inside the mounting groove 10, a screw rod 12 is connected to the output end of the motor 11, a connecting block 13 is threadedly connected to the outer wall of the screw rod 12, a guide rod 14 is provided at the bottom of the screw rod 12, and a movable plate 15 is provided at the top of the workbench 1;

[0025] It should be noted that the first cylinder 4 and the second cylinder 8 are connected by an external control switch, and the motor 11 is connected by an external power supply and the control switch.

[0026] Preferably: an opening is provided at the top of the workbench 1, and one end of the connecting block 13 is connected to the movable plate 15 through the opening at the top of the workbench 1, the movable plate 15 is located between the two limiting side plates 2, one end of the connecting block 13 is sleeved on the outer wall of the guide rod 14, and one end of the screw rod 12 forms a rotating connection structure with the workbench 1 through a bearing.

[0027] When in use, the stacked books are placed between the two limit side plates 2, and then the motor 11 is started to drive the screw 12 to rotate, so that the connecting block 13 with the threaded connection on the outer wall can move along the guide rod 14 under the action of the rotation of the screw 12, and the movable plate 15 connected to the top of the connecting block 13 will drive the push plate 17 to push the book to the bottom of the chamfering blade 9, thereby realizing the automatic feeding of the chamfering machine;

[0028] It should be noted that the book placed between the two limiting side plates 2 needs to have its chamfered side facing the baffle 5 so that it can collide with the baffle 5 after being pushed.

[0029] Preferably: two connecting rods 16 are passed through the surface of the movable plate 15, one end of the two connecting rods 16 is connected to a push plate 17, the other end of the two connecting rods 16 is connected to a limiting block 18, the outer walls of the two connecting rods 16 are sleeved with a spring 19, and the push plate 17 can form an elastic structure with the movable plate 15 through the connecting rods 16, the limiting block 18 and the spring 19.

[0030] When in use, through the elastic structure between the push plate 17 and the movable plate 15, when the book pushed by the push plate 17 contacts the baffle 5 and cannot be pushed further, the push plate 17 will squeeze the spring 19 to contract, thereby preventing the stacked books from tilting due to excessive force in pushing the books;

[0031] It should be noted that if the pushed book contacts the baffle 5 , it means that the book has been accurately moved below the chamfering blade 9 .

[0032] Working principle: When using the chamfering machine with a self-feeding structure for book production, first, place the stacked books between the two limiting side plates 2, and then start the motor 11 to drive the screw 12 to rotate, so that the connecting block 13 threadedly connected to its outer wall can move along the guide rod 14 under the action of the rotation of the screw 12, and the movable plate 15 connected to the top of the connecting block 13 will drive the push plate 17 to push the book to the bottom of the chamfering blade 9. When the book pushed by the push plate 17 contacts the baffle 5 and cannot be pushed further, the push plate 17 will squeeze the spring 19 to contract, thereby avoiding the situation where the stacked books are tilted due to excessive force in pushing the books. At this time, cutting and chamfering can be performed, and the first cylinder 4 is used to press down and fix the top of the book with its output end, and then the chamfering blade 9 is pressed down by the second cylinder 8 to cut and chamfer the book.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
