[0027] Please refer to Figure 4 As shown, the middle of the vibrating plate 23 is fixed with a baffle 3; the sliding plate 24 is located between the sieve plate 14 and the baffle 3; when the debris flows to the surface of the sieve plate 14 under the action of the airflow, part of the debris diffuses to the vibrating plate 23; the baffle 3 shields the cavity between the vibrating plate 23 and the sliding plate 24, reducing the debris entering between the vibrating plate 23 and the baffle 3, and reducing the dead angle area of the sieve plate 14 cleaned by the scraper 17 and the elastic plate 18.

[0028] Please refer to Figure 4 As shown, the middle of the sliding plate 24 is fixed with a plurality of brushes 4; the brushes 4 are arranged in an array; when the scraper 17 and the elastic plate 18 clean the debris on the surface of the sieve plate 14, a small amount of impurities enter the cavity between the sliding plate 24 and the vibrating plate 23; when the sliding plate 24 moves, the brushes 4 move together; the brushes 4 clean the debris in the cavity between the sliding plate 24 and the vibrating plate 23, so that the debris is swept out of the cavity under the thrust of the brushes 4, reducing the debris remaining on the surface of the sieve plate 14.

[0029] Please refer to Figure 2 and Figure 5As shown, the bottom of the box body 12 is provided with a groove 5; the inner wall of the groove 5 is inclined; the inner side wall of the groove 5 is provided through and is slidably connected with a collecting box 52; when the debris needs to be collected, the air pump can be stopped after the workpiece punching is finished, at this time the debris attached to the surface of the sieve plate 14 will fall to the inside of the groove 5 under the action of gravity and slide along the inclined surface of the groove 5, so that the debris can enter the inside of the collecting box 52, the worker can slide and pull out the collecting box 52 to recycle the debris, and the convenience of the device for collecting the debris is improved.

[0030] Please refer to Figure 5 As shown, the inner side wall of the groove 5 is fixedly connected with a plurality of guide plates 6; the guide plates 6 are equidistantly arranged; when the debris slides along the inclined surface of the groove 5, the debris will contact the guide plates 6, the guide plates 6 will limit and guide the path of the debris when sliding down, so that the debris enters the inside of the collecting box 52 in an orderly manner, the accumulation of the debris on the inner wall of the collecting box 52 is reduced, and the distribution of the debris in the collecting box 52 is optimized.

[0031] Please refer to Figure 4 As shown, the surface of the sliding plate 24 is an arc-shaped structure; because the surface of the sliding plate 24 is an arc-shaped structure, the resistance received by the elastic plate 18 and the sliding plate 24 when they contact is smaller, and the friction between the elastic plate 18 and the sliding plate 24 is reduced.

[0032] Working principle: The puncher body 1 will punch the workpiece, and the workpiece will produce debris when punching. At this time, the worker can connect the air pipe 13 to the air pump to make the airflow enter the air pipe 13 inside through the sieve plate 14. At this time, the surface of the sieve plate 14 is in a negative pressure state under the action of the airflow. These debris will flow to the surface of the sieve plate 14 with the airflow. The fan blade 16 will drive the rotating shaft 15 to rotate under the action of the airflow. The rotating shaft 15 will drive the scraper 17 and the elastic plate 18 to rotate. The scraper 17 will contact the debris accumulated on the surface of the sieve plate 14 when rotating. These debris will be redistributed under the scraping action of the scraper 17, reducing the blockage of the sieve plate 14 surface caused by the accumulation of debris. At the same time, when the elastic plate 18 rotates to the external corner area of the sieve plate 14 with the scraper 17, the elastic plate 18 will stretch under the action of its own elasticity and clean the debris accumulated in the external corner area, so that the device can clean the debris on the surface of the sieve plate 14 comprehensively. The elastic plate 18 can be made of wear-resistant material to increase the service life of the elastic plate 18. The scraper 17 will move with the connecting rod 2 and the first magnet 22 when rotating. The distance between the first magnet 22 and the second magnet 25 will change when the first magnet 22 moves. When the first magnet 22 and the second magnet 25 approach, the sliding plate 24 will move away from the vibrating plate 23 under the attraction and slide along the sieve plate 14. The spring 26 will be in a stretched state. Then the first magnet 22 will continue to move, and the sliding plate 24 will reset under the elastic force of the spring 26 and collide with the vibrating plate 23. The vibrating plate 23 will transmit the impact to the sieve plate 14 to make the surface of the sieve plate 14 vibrate. The debris blocked in the holes on the surface of the sieve plate 14 will fall off under the vibration. When the debris flows to the surface of the sieve plate 14 under the action of the airflow, some debris will spread to the vibrating plate 23. The baffle 3 will shield the cavity between the vibrating plate 23 and the sliding plate 24, reducing the debris entering the cavity between the vibrating plate 23 and the baffle 3, and also reducing the dead angle area of the sieve plate 14 surface cleaned by the scraper 17 and the elastic plate 18. When the scraper 17 and the elastic plate 18 clean the debris on the surface of the sieve plate 14, some impurities will enter the cavity between the sliding plate 24 and the vibrating plate 23. The sliding plate 24 will move with the brush 4. The brush 4 will clean the debris in the cavity between the sliding plate 24 and the vibrating plate 23, so that the debris will be swept out of the cavity under the pushing force of the brush 4. When the debris needs to be collected, the air pump can be stopped after the workpiece punching is completed. At this time, the debris attached to the surface of the sieve plate 14 will fall into the inside of the recess 5 under the action of gravity and slide along the inclined surface of the recess 5, so that the debris can enter the inside of the collection box 52. The worker can slide and pull out the collection box 52 to recycle the debris. When the debris slides along the inclined surface of the recess 5, the debris will contact the guide plate 6. The guide plate 6 will limit and guide the path of the debris when it slides down, so that the debris can enter the inside of the collection box 52 in an orderly manner, reducing the accumulation of debris on the inner wall of the collection box 52.

Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
