By setting the limit seats 41 and the plug-in grooves 42, when the U-shaped push rack 21 moves horizontally toward one side of the stacking plate 14, the U-shaped push rack 21 and the plate-like materials in the U-shaped push rack 21 enter the plug-in grooves 42, and the U-shaped frame 13 is provided with two slide grooves 43, and the middle parts of the two slide grooves 43 are slidably installed with sliders 44 A second connecting rod 45 is fixedly installed on the lower surface of the two sliders 44, one end of which is fixedly connected to the upper surface of a limit seat 41, and a moving frame 46 is fixedly installed on the upper surface of the two sliders 44. By driving the slider 44 to slide horizontally in the slide groove 43, the slider 44 can make the limit seat 41 move horizontally synchronously through the second connecting rod 45. When the two sliders 44 slide back to back, the two limit seats 41 move away from each other, and the plate-like material inserted in the insertion groove 42 falls downward from the opposite sides of the two limit seats 41 to the upper surface of the stacking plate 14.

[0030] A second rotating shaft 47 is rotatably mounted on the L-shaped frame 11, and a driving gear 48 is fixedly mounted on one end of the second rotating shaft 47. A plurality of teeth 49 evenly distributed are fixedly mounted on the two moving frames 46. The driving gear 48 is meshed with the teeth 49. By driving the second rotating shaft 47 to rotate, the second rotating shaft 47 can rotate the driving gear 48.

A second transmission rod 5 and a third transmission rod 51 are rotatably mounted on one side of the L-shaped frame 11. A second gear 52 is fixedly installed on one end and one end of the third transmission rod 51, and the two second gears 52 are meshed and connected. The sector gear 35 and one of the second gears 52 correspond horizontally. A synchronous wheel 53 is fixedly installed on one end of the third transmission rod 51 and the other end of the second rotating shaft 47. A synchronous belt 54 is installed between the two synchronous wheels 53. The second gear 52 is driven to rotate by the sector gear 35, and the meshing of the two second gears 52 can make the third transmission rod 51 rotate.

[0031] A spring rod 55 is fixedly installed at one end of the two slide grooves 43, and the telescopic end of one spring rod 55 is fixedly connected to one side of a slider 44. By setting the spring rod 55, when the two sliders 44 slide back to back, the two limit seats 41 are in a state of moving away from each other, and the two sliders 44 stretch the two spring rods 55. When the driving of the two sliders 44 stops and the two sliders 44 stop sliding back to back, the two spring rods 55 shrink and reset, pulling the two sliders 44 to slide toward each other and reset, so that the two limit seats 41 are close to each other and reset, allowing the next plate material to enter.

[0032] The material receiving mechanism 6 includes a lifting frame 61, a connecting frame 62 is fixedly installed on one side of the lifting frame 61, one end of the connecting frame 62 is fixedly connected to the lower surface of the stacking plate 14, and by driving the lifting frame 61 to vertically descend, the lifting frame 61 can make the stacking plate 14 vertically descend synchronously through the connecting frame 62, so that the next plate-shaped material can be stacked on the stacking plate 14, and two third rotating shafts 68 are rotatably installed on the L-shaped frame 11, and one end of the two third rotating shafts 68 is fixedly installed with a transmission wheel 69, and a transmission is installed between the two transmission wheels 69.

One end of the driving rod 71 is in movable contact with one end of the movable groove 72. By driving the third rotating shaft 68 to rotate, the third rotating shaft 68 can transmit the transmission belt 7 through the transmission wheel 69. The transmission belt 7 can make the lifting frame 61 reciprocate through the cooperation of the driving rod 71 and the movable groove 72. The lifting frame 61 can synchronously reciprocate the stacking plate 14 through the connecting frame 62. When rising, the stacking plate 14 can be raised and reset.

[0033] Two second guide grooves 63 are provided on the L-shaped frame 11, and second guide blocks 64 are slidably installed at one end of the two second guide grooves 63. One side of the two second guide blocks 64 is fixedly connected to the lifting frame 61. By providing the second guide grooves 63 and the second guide blocks 64, the second guide blocks 64 can slide in the vertical direction along the inner wall of the second guide grooves 63, thereby guiding the lifting frame 61 in the vertical direction, so that the lifting frame 61 can be lifted and lowered in the vertical direction. A third guide groove 65 is provided on the side frame 12, and a third guide block 66 is slidably installed at one end of the third guide groove 65. A second fixing rod 67 is fixedly installed on one side of the third guide block 66, and one end of the second fixing rod 67 is fixedly connected to one side of the stacking plate 14. By providing the third guide groove 65, the third guide block 66 and the second fixing rod 67, the third guide block 66 can slide in the vertical direction along the inner wall of the third guide groove 65, thereby guiding the stacking plate 14 in the vertical direction through the second fixing rod 67, so that the stacking plate 14 can be lifted and lowered in the vertical direction, thereby improving the stability of the stacking plate 14.

[0034] A second motor 73 is fixedly installed on one side of the L-shaped frame 11, and a second rotating rod 74 is fixedly installed on the driving output end of the second motor 73, a worm 75 is fixedly installed on one end of the second rotating rod 74, and a worm wheel 76 is fixedly installed on the other end of one of the third rotating shafts 68, and the worm 75 and the worm wheel 76 are meshingly connected. By turning on the second motor 73, the driving shaft of the second motor 73 can rotate the worm 75 through the second rotating rod 74, and the worm 75 can rotate the third rotating shaft 68 through the worm wheel 76. At the same time, when the stacking plate 14 stops descending, the self-locking of the worm 75 and the worm wheel 76 prevents the stacking plate 14 from descending due to its own weight, thereby keeping the stacking plate 14 stationary during the stopping and descending process.

[0035] Working principle: When it is necessary to demonstrate the automatic stacking of plate-like materials to students, the external conveyor belt is passed between the stacking plate 14 and the U-shaped push rack 21; The external conveyor belt conveys batches of plate-like materials. When a single plate-like material is located between the U-shaped pushing rack 21 and the stacking plate 14, the teaching staff first starts the first motor 33. The driving shaft of the first motor 33 rotates the fan gear 35 through the first rotating rod 34. The fan gear 35 first drives the first gear 36 to rotate. The first gear 36 rotates the first rotating shaft 25. The first rotating shaft 25 rotates the first transmission rod 26 through two bevel gears 27. The first transmission rod 26 rotates the push-pull shaft 3 with the axis of the connecting shaft 29 as the center of the circle through the rotating handle 28 and the connecting shaft 29. The push-pull shaft 3 moves the U-shaped push rack 21 horizontally toward one side of the stacking plate 14 through the U-shaped seat 32 and the first connecting rod 31. At this time, the U-shaped push rack 21 gradually engages with the single plate-like material on the conveyor belt. The U-shaped push rack 21 pushes the single plate-like material to move horizontally synchronously during the horizontal movement. The two ends of the U-shaped push rack 21 enter the two plug-in grooves 42 together with the single plate-like material. The U-shaped push rack 21 moves horizontally in the opposite direction (the sector gear 35 drives the first gear 36 to rotate one circle) and disengages from the two plug-in grooves 42, and the single plate-like material stays between the two plug-in grooves 42. As the U-shaped pushing frame 21 reciprocates horizontally for a stroke, the sector gear 35 disengages from the first gear 36 and meshes with one of the second gears 52. The sector gear 35 rotates the third transmission rod 51 through the cooperation of the two second gears 52. The third transmission rod 51 rotates the second rotating shaft 47 through the two synchronous wheels 53 and the synchronous belt 54. The second rotating shaft 47 rotates the driving gear 48. The driving gear 48 moves the two moving frames 46 away from each other through a plurality of teeth 49. The two moving frames 46 move the two limit seats 41 away from each other through the two sliders 44 and the two second connecting rods 45. At the same time, the two sliders 44 squeeze the piston ends of the two spring rods 55 to contract (for subsequent resetting). The separation of the two limit seats 41 causes the single sheet of plate-like material inserted in the two insertion slots 42 to fall downward onto the stacking plate 14. When the sector gear 35 is disengaged from one of the second gears 52 , the two spring rods 55 are extended and reset, so that the two limit seats 41 are close to each other and reset to the initial state; At this time, the teaching staff turns on the second motor 73, and the driving shaft of the second motor 73 rotates the worm 75 through the second rotating rod 74, and the worm 75 rotates the corresponding third rotating shaft 68 through the worm wheel 76. At this time, the two third rotating shafts 68 transmit the transmission belt 7 through the transmission wheel 69, and the transmission belt 7 lowers the lifting frame 61 through the cooperation of the driving rod 71 and the movable groove 72 (the lowering height is the thickness of a single sheet of plate-like material), and the lifting frame 61 lowers the stacking plate 14 synchronously through the connecting frame 62, and then according to the above-mentioned operating steps, the automatic stacking of batch plate-like materials is completed.
