Preferably, a shrapnel feeding turntable 101 is further arranged in front of the shrapnel cutting mechanism 9, and a plurality of shrapnel feeding clips 102 are annularly arranged on the shrapnel feeding turntable 101. When the device works, the shrapnel 200 cut by the shrapnel cutting mechanism 9 is clamped and taken away by the shrapnel feeding clip 102, and the shrapnel 200 clamped on the shrapnel feeding clip 102 is fed to the next process by the shrapnel feeding turntable 101.

The working principle of the spring plate feeding and cutting device 100 of the invention is as follows: before the beginning of feeding and cutting the shrapnel 200, the position of the shrapnel feeding and cutting device 100 is adjusted, which specifically comprises: the left and right positions of the left and right adjusting bases 13 are finely adjusted by rotating the second adjusting bolts 16 at the left and right ends of the supporting base 1, and further, fine adjustment of the left and right positions of each part arranged on the left and right adjusting bases 13 is realized; the fine adjustment of the front and rear positions of the front and rear adjusting bases 14 is realized by rotating the third adjusting bolts 17 at the front and rear ends of the supporting base 1, so that the fine adjustment of the front and rear positions of each part arranged on the front and rear adjusting bases 14 is realized;

in actual operation, the step pitch value of the stamped elastic sheets 200 is uniform, so that the step pitch value of each elastic sheet 200 feeding is fixed; therefore, the rear slider adjusting mechanism 24 and the oblique block adjusting mechanism 53 need to be matched with each other, the position of the rear slider 2 is slightly adjusted by the rear slider adjusting mechanism 24, and the positions of the two oblique blocks 5 are slightly adjusted by the oblique block adjusting mechanism 53, so that the rear slider 2 moves forwards by a fixed step distance under the action of the inclined surface 51 when the oblique blocks 5 descend at each time, and just one elastic sheet 200 can be pushed forwards at each time.

After the position of the shrapnel feeding and cutting device 100 is adjusted, the shrapnel feeding and cutting device 200 starts to comprise: placing the elastic sheet 200 to be cut above the push claw 21 and the front stop block 31, and making the push claw 21 in the rear slide block 2 bounce to a gap between two uncut elastic sheets 200 under the action of the elastic force of the second pressure spring 22; the lifting mechanism 6 drives the two inclined blocks 5 to synchronously descend and enables the inclined surfaces 51 to be in contact with the cam followers 23 on the two sides of the rear sliding block 2, the cam followers 23 on the two sides of the rear sliding block 2 push the rear sliding block 2 to move forwards under the action of the inclined surfaces 51 of the two inclined blocks 5, so that the elastic sheet 200 is pushed forwards, at the moment, the bottom cambered surface of the elastic sheet 200 above the front stop block 31 slides over the front stop block 31, and the front stop block 31 is slightly pressed downwards under the action of the bottom cambered surface of the elastic sheet 200;

when the lifting mechanism 6 drives the two inclined blocks 5 to descend to the right position, the push claw 21 of the rear sliding block 2 just pushes one elastic sheet 200 forwards, meanwhile, the elastic sheet 200 at the foremost end is cut off under the matching of the top knife 94 and the bottom knife 93, and the front stop block 31 bounces upwards to a gap between the two uncut elastic sheets 200 under the action of the elastic force of the third pressure spring 32; the lifting mechanism 6 drives the two inclined blocks 5 to synchronously ascend and return to separate the inclined plane 51 from the cam followers 23 on the two sides of the rear sliding block 2, the rear sliding block 2 automatically returns back under the action of the elastic force of the first pressure spring 4, and the uncut elastic sheet 200 is stopped by the front stop block 31 and cannot be taken away backwards together; in the process that the rear sliding block 2 returns to the back position, the push claw 21 is slightly pressed down under the action of the bottom cambered surface of the elastic sheet 200, and after the rear sliding block 2 returns to the original position backwards, the push claw 21 bounces to a gap between the two elastic sheets 200 which are not cut off under the action of the elastic force of the second pressure spring 22 to prepare for next elastic sheet 200 feeding and cutting.

Although specific embodiments of the invention have been described above, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the appended claims.
