[0031] The first motor 10 is driven to rotate the positive and negative screw 12 to move the two movable arms 7 on the positive and negative screw 12 to the middle along the corresponding chute 6, so as to move the two limiting plates 8 to the middle, until the spacing of the two limiting plates 8 meets the requirement of limiting the front and rear directions of the plate, by arranging the limiting plate 8 on the guide platform 3 corresponding to the front and rear, the plate during blanking can be limited in the front and rear directions, avoiding the plate from falling from the front and rear directions during blanking, prompting the plate to accurately enter the receiving box 13 on the right side for collection, improving the accuracy and efficiency of the plate shearing machine blanking and material collecting process.

[0032] Mainly refer to Figure 1As shown, the right side of the bottom plate 1 is provided with a storage box 13, which is provided as a left opening half-enclosed structure, and the inner cavity of the storage box 13 is provided with a supporting plate 14 from left to right and inclined upward. The right end of the guide platform 3 is provided with a blanking plate 15 through a pin shaft rotation, which is inclined downward from left to right and arranged in the inner cavity of the storage box 13. The right wall of the bottom plate 1 is provided with a mounting strip 30, and the left wall of the storage box 13 is provided with a mounting groove 29. The mounting strip 30 is slidably embedded in the mounting groove 29.

When the far heart side of the cam 25 is rotated to the left side wall of the moving plate 22, the moving plate 22, the connecting frame 18 and the push plate 19 are simultaneously moved to the right side to force the telescopic rod 20 to shrink and the spring 21 to compress. At this time, the push plate 19 extends out of the through slot 16 to the right side and exerts a rightward pushing force on the plate material at the blanking plate 15, so as to make the plate material tilt to the right side until it abuts against the side wall of the supporting plate 14. When the near heart side of the cam 25 rotates to the left side wall of the moving plate 22, the telescopic rod 20 is forced to shrink under the elastic force of the spring 21, and the moving plate 22, the connecting frame 18 and the push plate 19 are moved to the left side. The push plate 19 is retracted to the left side of the blanking plate 15, ready for the next push of the plate material on the right side of the blanking plate 15.

The connecting plate 27 and the supporting rod 28 are controlled to descend synchronously by the gas cylinder 26, so as to gradually make the right end of the plate material on the supporting rod 28 fall to the left upper side of the conveying device 4. The plate material is conveyed to the right side by the opened conveying device 4, which can avoid the impact force caused by the direct falling of the plate material. The above lifting assembly has the same effect as the electric cylinder, lifting rod, connecting rod and supporting rod in the prior art (publication No. CN217800494U), which will not be described and limited here.
