Axis connection), one end of the rotating arm 509 is hinged to the second end of the connecting rod 504 (axis connection), and the other end of the rotating arm 509 is connected to the first side wall of the fixed partition 304 through the driving shaft 510; the driving shaft 510 and the rotating arm 509 are connected by a key, and after the driving shaft 510 passes through the rotating arm 509 and the fixed partition 304, the protruding end is driven to rotate by the worm gear transmission mechanism; and the driving shaft 510 can rotate freely relative to the fixed partition 304.

[0038] Preferably, the worm gear transmission mechanism includes a worm 514, a worm wheel 511 connected to the worm 514, the worm wheel 511 is sleeved outside the drive shaft 510, and the two are connected by a key; the worm 514 is rotatably connected to the second side wall of the fixed partition 304 through the transmission shaft; wherein the transmission shaft support 512 is fixed to the second side wall of the fixed partition 304; the worm 514 is supported by the transmission shaft supports 512 at both ends thereof, and the worm 514 can rotate freely relative to the transmission shaft; and the worm 514 is driven to rotate by the motor 515. Because there are two arm units, the drive shafts 510 of the two arm units can each be connected to a worm wheel 511, and the two worm wheels 511 are connected to the same worm 514 and driven by the same motor 515. It saves space and meets the transmission requirements.

[0039] Specifically, the motor 515 drives the worm 514 to rotate, and the worm wheel 511 connected to the worm 514 rotates accordingly, driving the drive shaft 510 to rotate; the rotating arm 509 connected to the drive shaft 510 rotates 360 degrees along the drive shaft 510, driving the connecting rod 504 and the swing arm 506 to perform a crank rocker mechanism-like movement, realizing the elliptical trajectory movement of point A.

[0040] Preferably, the support arm 502 adopts a strip plate structure, and the top of the support arm 502 is supported on the bottom of the plate body; and the top of the support rod is fixedly connected to the bottom of the support plate, and the bottom of the support rod is hinged to the connecting rod 504 through a second pin 503; the swing arm 506 adopts a (runway-type block structure) block structure, one end of the swing arm 506 is hinged to the fixed partition 304 through a fixed pin 507, and the other end of the swing arm 506 is hinged to the first end of the connecting rod 504 through a third pin 505; the swivel arm 509 adopts a (runway-type block structure) block structure, and one end of the swivel arm 509 is hinged to the second end of the connecting rod 504 through a first pin 508.

During the lifting process of the plate body, the cut material on the grid is lifted up; then in the descending stage of the elliptical operation of the plate, the cut material is pushed forward and descended. After that, the plate falls to the lowest point, and the material falls to the previous adjacent grid; at this time, point a rises back and forth again to realize the next step of lifting; the cycle is repeated, and finally the material is moved forward in steps; finally, all the materials are unloaded.

[0047] The motor 515 is started, and the motor 515 drives the transmission shaft to rotate, and the transmission shaft drives the worm gear to mesh, and the worm gear 511 drives the drive shaft 510 to rotate.

[0048] The driving shaft 510 drives the rotating arm 509 to make a circular motion. When the driving shaft 510 drives the rotating arm 509 to make a circular motion, the swing arm 506 swings with the fixed pin shaft 507 according to a certain rule (swings symmetrically at a certain angle), and the connecting rod 504 moves in an elliptical shape according to a certain rule. The motion trajectory of point A on the connecting rod 504 is shown in 12.

[0049] The motion trajectory of point A on the connecting rod 504 is also the motion trajectory of the material moving mechanism 501 . The motion trajectory of the material moving mechanism 501 can realize that the plates on the grid are moved out step by step and then dropped into the material box 2 .

[0050] When the material moving mechanism 501 is at the upper end of the motion track, the upper end of the material moving mechanism 501 is required to be higher than the top of the grid (so that the sheet material on the grid can be lifted up and moved forward).
