[0024] In the present invention, the staff first places the plate 2 on the top of the CNC shearing machine workbench 1, presses the rear end of the plate 2 against the front end of the push plate 12, starts the motor 4, and drives the transmission rod 5 to rotate through the output end of the motor 4. When the transmission rod 5 rotates one circle, the belt 6, the rotating rod 7, the large gear 8, the small gear 9, and the threaded rod 10 are rotated through the rotation of the transmission rod 5, so that the push plate 12 pushes the plate 2 to move, and because the large gear 8 is an incomplete gear, the large gear 8 rotates one circle and intermittently engages with the small gear 9 to drive the small gear 9 to rotate intermittently.

When the large gear 8 and the small gear 9 are no longer engaged, the plate 2 remains stationary, and the shearing knife 21 moves downward to shear the stationary plate 2. When the large gear 8 and the small gear 9 are engaged, the plate 2 moves. In this process, the shearing knife 21 moves upward and separates from the plate 2 without affecting the movement of the plate 2. The material of the plate 2 is wood, which is easy to be sheared.

[0027] Dust will be generated during shearing. At this time, the negative pressure fan 33 is started. The air in the dust box 30 can be sucked away through the negative pressure fan 33 and the second connecting pipe 32 to form a negative pressure. The dust-containing air from the outside is injected into the dust box 30 through multiple dust suction heads 28, the annular tube 27, and the first connecting pipe 29. The filter net 31 arranged in the dust box 30 can filter and intercept the dust in the air, and the dust generated by shearing is collected in the dust box 30, so that the air quality is good and the health of personnel is protected.
