The lower side of the push paper board 52 is bent at a right angle toward the direction close to the second conveyor belt 51. The push paper board 52 is slidably connected to the second conveyor belt 51 along the length direction of the frame 1. The discharge end of the second conveyor belt 51 is rotatably connected to a first lead screw 53 provided along the width direction of the second conveyor belt 51. The first lead screw 53 passes through the side of the push paper board 52 away from the second conveyor belt 51 and is threadedly connected to the push paper board 52. A second motor 54 is installed at the end of the first lead screw 53.
[0057] A first limit plate 55 is provided on the upper side of the first conveyor belt 31 and is arranged vertically along the width direction of the frame body 1. The upper side of the first limit plate 55 is rotatably connected to the limit shaft 551. The end of the first rack 62 away from the dividing paper board 41 is located on the upper side of the first conveyor belt 31 and is fixedly connected to the upper side of the stabilizing frame 3.

[0058] A second limiting plate 56 is provided on the upper side of the second conveyor belt 51 and is vertical and parallel to the width direction of the second conveyor belt 51. The second limiting plate 56 is slidably connected to the second conveyor belt 51 along the length direction of the second conveyor belt 51. The side of the second conveyor belt 51 close to the dividing paper board 41 is rotatably connected to a third lead screw 561 provided along the length direction of the second conveyor belt 51. The third lead screw 561 passes through and is threadedly connected to the end of the second limiting plate 56, and a sixth motor 562 is installed at the end of the third lead screw 561.
[0059] A vertical mounting plate 57 is provided at one end of the second conveyor belt 51 close to the first conveyor belt 31. The mounting plate 57 is slidably connected to the stabilizing frame 3 along the length direction of the frame body 1. Two third sprocket wheels 571 are rotatably connected to one side of the stabilizing frame 3 close to the mounting plate 57. A second chain 572 is mounted on the mounting plate 57, which is sleeved on the outside of the third sprocket wheels 571 and meshed with the third sprocket wheels 571. A seventh motor (not shown in the figure) is mounted on the stabilizing frame 3 to drive one of the third sprocket wheels 571 to rotate. The second conveyor belt 51 is slidably connected to the mounting plate 57 in the vertical direction. A vertical second lead screw 58 is mounted on one side of the mounting plate 57 close to the second conveyor belt 51.

An eighth motor 581 fixedly connected to the mounting plate 57 is mounted at the end of the second lead screw 58.
[0060] The third gear 552 is driven to rotate and the relative position of the first limit plate 55 on the first conveyor belt 31 is adjusted under the drive of the first rack 62. The third lead screw 561 rotates and adjusts the position of the second limit plate 56 on the second conveyor belt 51, and the cardboard is pushed onto the first conveyor belt 31 until it abuts against the first limit plate 55, thereby reducing the possibility that the side of the cardboard close to the dividing cardboard 41 is difficult to align with the pushing cardboard 52. The first conveyor belt 31 conveys the cardboard to the second conveyor belt 51, and the second conveyor belt 51 continues to drive the cardboard to move until it abuts against the second limit plate 56. At this time, the second motor 54 drives the first lead screw 53 to rotate and drives the pushing cardboard 52 to push the cardboard to move toward the direction close to the paper laminating machine and load the material.
[0061] The third sprocket 571 adjusts the position of the mounting plate 57 in the length direction of the frame 1 through the second chain 572, thereby adjusting the position of the second conveyor belt 51 on the stabilizing frame 3, and driving the second lead screw 58 to rotate so as to facilitate driving the position of the second conveyor belt 51 on the mounting plate 57, thereby facilitating the adjustment of the position of the second conveyor belt 51 in the height direction of the stabilizing frame 3, until the cardboard on the second conveyor belt 51 is aligned with the loading position of the paper laminating machine, thereby facilitating loading of the paper laminating machine.
[0062] The implementation principle of Example 1 is as follows: the stacked cardboard is moved onto the tray 12 through the tray 12, the cardboard is moved upward to adapt to the separating cardboard 41, the separating cardboard 41 and the supporting plate 44 drive the cardboard to separate from the tray 12 and move to the first conveyor belt 31, at this time the first conveyor belt 31 drives the cardboard to move to the second conveyor belt 51, and the cardboard is sent into the laminating machine through the pushing cardboard 52. Example
[0063] Reference Fig. 9 and Fig.10 The difference between this embodiment and the first embodiment is that a mounting shaft 7 parallel to the length direction of the frame body 1 is provided between adjacent connecting plates 322, and the mounting shaft 7 is rotatably connected to the corresponding two connecting plates 322. Two adjacent connecting plates 322 form a group, and both ends of the mounting shaft 7 on the side close to each other of each group of connecting plates 322 are sleeved with torsion springs 71, and the torsion springs 71 on the same mounting shaft 7 are fixedly connected to the connecting plate 322 away from the step 321 at one end close to each other, and the other end is fixedly connected to the connecting plate 322 close to the step 321. When the torsion springs 71 are at their original length, the side of the connecting plates 322 corresponding to the torsion springs 71 that are close to each other bulges upward.
[0064] Along the width direction of the frame body 1, the ends of the installation shafts 7 located between two adjacent torsion springs 71 close to the stabilizing frame 3 are inserted into the stabilizing frame 3 and are slidably and rotatably connected to the stabilizing frame 3, and the other ends are inserted into the frame body 1 and are slidably and rotatably connected to the frame body 1. The two ends of the connecting plate 322 away from the step 321 away from the step 321 are fixedly connected with the rotating columns 72, the rotating column 72 close to the stabilizing frame 3 is inserted into the stabilizing frame 3 and is rotatably connected to the stabilizing frame 3, and the other rotating column 72 is inserted into the frame body 1 and can be rotatably connected to the frame body 1.
[0065] The connecting plate 322 near the step 321 is fixedly connected to fixing columns 73 at both ends of the side near the step 321. The fixing column 73 near the stabilizing frame 3 is inserted into the stabilizing frame 3 and is slidably and rotatably connected to the stabilizing frame 3. The other fixing column 73 is inserted into the frame body 1. The frame body 1 is provided with a driving component 8 for driving the connecting plate 322 to fold.
[0066] When the cardboard is manually placed on the first conveyor belt 31, the driving component 8 drives the connecting plate 322 close to the step 321 to move at one end close to the step 321 in a direction away from the step 321, so that it rotates and moves under the drive of the torsion spring 71, and is folded to the side of the frame 1 away from the step 321, so that it is convenient for the cardboard to be manually moved to the first conveyor belt 31. When the cardboard is loaded through the dividing cardboard 41, the driving component 8 drives the connecting plate 322 to move and unfold, so that the cardboard can be moved to the first conveyor belt 31 through the connecting plate 322, so as to meet different working conditions.
[0067] Reference Fig.10 , Fig.11 and Fig.12 The driving assembly 8 includes a driving block 81 which is sleeved on a fixed column 73 inserted into the frame body 1. The ends of the mounting shaft 7 inserted into the frame body 1 are sleeved and rotatably connected with a connecting block 82. The frame body 1 is provided with a driving groove 13 which is adapted to the driving block 81 and is arranged along the width direction of the frame body 1. The driving block 81 and the connecting block 82 are both inserted into the driving groove 13 and are slidably connected to the frame body 1.
[0068] A fourth lead screw 83 is provided in the driving groove 13 and is arranged along the width direction of the frame body 1 and is rotatably connected to the frame body 1. The fourth lead screw 83 is arranged to be a reciprocating lead screw. The driving block 81 is sleeved on the fourth lead screw 83 and is threadedly connected to the fourth lead screw 83. The connecting blocks 82 are sleeved on the fourth lead screw 83 and are slidably connected to the fourth lead screw 83. A rotating part 84 for driving the fourth lead screw 83 to rotate is provided on the workbench 32.
[0069] The rotating member 84 drives the fourth lead screw 83 to rotate and drives the driving block 81 to move away from the step 321 and squeeze the other connecting plates 322, thereby cooperating with the torsion spring 71 and folding the connecting plates 322 to one side of the frame 1, making it easier to manually place the cardboard on the first conveyor belt 31 and reducing the possibility of manual disassembly of the connecting plates 322.
[0070] One end of the fourth lead screw 83 near the step 321 passes through the frame 1, and the rotating member 84 includes a ratchet 841 which is sleeved and fixedly connected to one end of the fourth lead screw 83 passing through the frame 1 and is rotatably connected to the fourth lead screw 83. A gear ring 842 is sleeved on the outer side of the ratchet 841, and two pawls 843 engaged with the ratchet 841 are hinged on the inner side wall of the gear ring 842, and a vertical second rack 844 is engaged on one side of the outer side of the gear ring 842. A horizontal driving plate 845 is provided on the step 321, and a control groove 3211 adapted to the driving plate 845 is opened on the step 321. The lower side of the driving plate 845 is inserted into the control groove 3211 and is slidably connected to the step 321 in the vertical direction, and a spring 846 connecting the lower side of the driving plate 845 and the step 321 is installed between the lower side of the driving plate 845 and the step 321.
[0071] A fixing rod 85 facing the second rack 844 is fixedly connected to the upper side of the driving plate 845 near one end of the second rack 844, and a control rod 86 vertically connected to the side wall of the frame 1 is fixedly connected to the lower end of the second rack 844. A hinge rod 87 connecting the control rod 86 and the fixing rod 85 is provided between the control rod 86 and the fixing rod 85. Both ends of the hinge rod 87 are provided with waist-shaped holes 871, and the fixing rod 85 and the control rod 86 are slidably and rotatably connected to the hinge rod 87 through the waist-shaped holes 871. The hinge rod 87 is hinged to the side wall of the workbench 32, and the hinge point of the hinge rod 87 is located on the side near the driving plate 845.
[0072] When the staff member goes up the step 321, he squeezes the driving plate 845, thereby driving the second rack 844 to move upward and drive the ring gear 842 to rotate through the fixing rod 85, the control rod 86 and the hinge rod 87. At this time, the ratchet 841 and the pawl 843 make the ring gear 842 and the fourth screw 83 relatively fixed, so that the ring gear 842 drives the fourth screw 83 to rotate and drives the driving block 81 to move to the end of the fourth screw 83 away from the step 321. At this time, the connecting plate 322 is folded. When the person leaves the driving plate 845, the spring 846 pushes the driving plate 845 to drive the second rack 844 to reset and drive the ring gear 842 to reverse. At this time, the ring gear 842 and the fourth screw 83 are not fixed. After the manual placement is completed, when moving from the step 321 to the ground, the driving plate 845 is squeezed again. At this time, the fourth screw 83 rotates and drives the driving block 81 to reset. At this time, the connecting plate 322 is unfolded.
[0073] Reference Fig.10 , Fig.11 and Fig.13 Three abutment rods 9 corresponding to the torsion springs 71 close to the stabilizing frame 3 are slidably connected to one side of the stabilizing frame 3 close to the connecting plate 322. The upper ends of the abutment rods 9 abut against the connecting plates 322 on both sides of the corresponding torsion springs 71 at the same time. Cams 91 are provided at the lower ends of the abutment rods 9. The side arms of the cams 91 are always abutted against the lower sides of the abutment rods 9. A control shaft 92 rotatably connected to the side wall of the stabilizing frame 3 is passed through and fixedly connected at the axis of the cams 91.
[0074] One end of the control shaft 92 close to the step 321 is fixedly connected to the sixth gear 93, and a vertical third rack 94 is meshed on one side of the sixth gear 93. The lower end of the third rack 94 is fixedly connected to a stabilizing rod 95, and the lower end of the stabilizing rod 95 is bent toward the direction close to the driving plate 845 and fixedly connected to the driving plate 845, and the bent end of the stabilizing rod 95 is slidably connected to the step 321.
[0075] The driving plate 845 moves downward and drives the third rack 94 to move downward through the stabilizing rod 95 and drives the sixth gear 93 to drive the control arm shaft to rotate, thereby facilitating the driving cam 91 to rotate and squeeze the abutment rod 9 upward, so that the abutment rod 9 lifts up the connecting plates 322 on both sides of the torsion spring 71, making it easier to fold the connecting plates 322.
[0076] The implementation principle of Example 2 is: when the staff goes up the step 321, they squeeze the driving plate 845 and drive the second rack 844 to move upward and drive the ring gear 842 to rotate. At this time, the ring gear 842 drives the fourth screw 83 to rotate and drives the driving block 81 to move to the end of the fourth screw 83 away from the step 321. At this time, the connecting plate 322 is folded. When the person leaves the driving plate 845, the spring 846 pushes the driving plate 845 to drive the second rack 844 to reset and drive the ring gear 842 to reverse. At this time, the ring gear 842 and the fourth screw 83 are not fixed. After the manual placement is completed, when moving from the step 321 to the ground, the driving plate 845 is squeezed again. At this time, the fourth screw 83 rotates and drives the driving block 81 to reset. At this time, the connecting plate 322 is unfolded.
