The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:

examples

As shown in fig. 1-3, an embodiment of a beveling apparatus for automatically beveling paper sheets includes a machine table 1, a beveling assembly 2 and a paper suction assembly 3, both of which are disposed on the machine table 1; a placing cavity 101 for placing documents is arranged on the machine table 1; the bevel component 2 is positioned at the end corner of the placing cavity 101; the bevel component 2 comprises a shifting piece 201, a first driving piece 202 for driving the shifting piece 201 to move towards the placing cavity 101, a turnover plate 203 connected with the shifting piece 201 in a rotating shaft mode, and a first driving mechanism 204 for driving the turnover plate 203 to rotate towards the shifting piece 201, wherein a certain included angle is formed between the turnover plate 203 and the shifting piece 201 in an initial state; the paper suction assembly 3 includes a suction mechanism 301 for sucking the paper and a second driving mechanism 302 for driving the suction mechanism 301 to move in the vertical direction. The suction mechanism 301 may suck the paper by generating a negative pressure or static electricity.

In this embodiment, the reset portion 205 is disposed on the pick 201 and used for pushing the turning plate 203 to rotate and reset, and the reset portion 205 may be an elastic member disposed between the pick 201 and the turning plate 203, the elastic member is specifically a torsion spring disposed at a connection position of the turning plate 203 and a rotating shaft of the pick 201, and after the turning plate 203 completes the angle folding, the torsion spring drives the turning plate 203 to reset after the first driving mechanism 204 resets. The first driving mechanism 204 does not need to be connected with the turnover plate 203, because the first driving element 202 only needs to drive the shifting piece 201 to move, and does not need to move together with the first driving mechanism 204, the moving load of the first driving element 202 is reduced, the connection of each component on the mechanical structure is reduced, and the structure of the device is simplified. Meanwhile, the torsion spring can enable the folding plate 203 to be attached to the shifting piece 201, and the folding effect is better. In order to prevent the torsion spring from driving the folded plate 203 to excessively reset, a blocking portion 206 for limiting the folded plate 203 may be disposed on the pick 201, so that the maximum angle between the folded plate 203 and the pick 201 is limited within a certain suitable angle, and the first driving mechanism 204 is convenient to contact with the folded plate 203.

Specifically, the first driving mechanism 204 includes a striker 2041 and a second driver 2042 for driving the striker 2041 to rotate the flap 203. The second driving member 2042 drives the striking rod 2041 to collide with the flipping panel 203, and simultaneously drives the flipping panel 203 to move toward the pick 201. In the present embodiment, the striking rod 2041 includes a swing arm portion 2411 and a striking portion 2412; one end of the swing arm 2411 is connected to the second driving element 2042, and the other end is connected to the impact portion 2412; the impact portion 2412 is arcuate. Because the movement path of the turnover plate 203 rotating around the plectrum 201 is arc-shaped, the swing arm 2411 also drives the impact part 2412 to do movement with the movement path being arc-shaped when rotating, and meanwhile, the impact part 2412 is also arc-shaped, so that the movement of the impact rod 2041 can be consistent with the movement of the turnover plate 203, and the turnover plate 203 can be smoothly driven to rotate after the impact rod 2041 collides with the turnover plate 203.

Specifically, the angle folding device further includes a fold limiting member 4 disposed on the machine table 1 and a third driving member for driving the fold limiting member 4 to move toward the shifting piece 201. Before the turning plate 203 rotates towards the direction of the turning plate 201, the third driving piece drives the crease limiting piece 4 to rotate and extend into the document cavity, the crease limiting piece 4 and the turning plate 201 clamp the paper of the document together, the crease limiting piece 4 is in line contact with the joint of the rotating shaft of the turning plate 203, then the turning plate 203 rotates towards the direction of the turning plate 201, so that when the turning plate 203 turns up the end angle, the movement of the paper is limited, and the crease of the turning angle is on the line contact with the joint of the rotating shaft of the crease limiting piece 4 and the turning plate 203 every time.

In the present embodiment, the first driving element 202, the second driving element 2042 and the third driving element can be all motors, because the plectrum 201, the striking rod 2041 and the crease limiter 4 are mainly in rotation motion, the motors are easy to arrange and use.

After the paper is driven to rise for a certain distance by the adsorption mechanism 301, the paper falls down because the motion resistance of the paper is increased or the adsorption of the adsorption mechanism 301 is stopped, and the end angle of the paper is positioned on the turnover plate 203. At this time, the third driving element drives the crease limiting element 4 to rotate, the crease limiting element 4 and the shifting piece 201 press the paper together and are in contact with the rotating position of the turnover plate 203, then the second driving element 2042 drives the impact rod 2041 to swing, and drives the turnover plate 203 to rotate towards the direction of the shifting piece 201, so that the end angle of the paper on the turnover plate 203 is driven to turn over the paper on the shifting piece 201, and a break angle is formed.

The stamping machine provided with the angle folding device further comprises a fixing device, a page turning device, a stamping device and other structures, wherein the fixing device, the page turning device, the stamping device and other structures are shown in the prior art and are not described in detail herein.
