[0002] Items such as corrugated cartons and paper boxes produced are usually stacked on a pallet first, and then the pallet with the cartons is temporarily placed aside and stacked up with a forklift etc. waiting for shipment. However, the cartons at the bottom layer of the stacked cartons are easily crushed, causing economic losses to the manufacturer. Moreover, the cartons at the upper layer need to be stacked with a forklift, which is not only cumbersome to operate but also extremely inconvenient to disassemble. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a carton stacking device as Figures 1-4 shown, which includes a bottom plate 1. Four screws 2 are rotatably connected to the upper surface of the bottom plate 1 in a rectangular array. A plurality of bearing plates 3 are slidably sleeved on the outer walls of the four screws 2 at equal intervals. Four threaded collar rings 4 are arranged in a rectangular array at the bottom of the bearing plate 3, and the inner wall of the threaded collar ring 4 is threadedly sleeved with the screw 2. A plurality of through holes 6 are equidistantly formed on the outer wall of the screw 2. A sliding hole 7 is formed on the front surface of the threaded collar ring 4. A limiting rod 8 is slidably sleeved in the inner cavity of the sliding hole 7. When the limiting rod 8 is slidably sleeved with the sliding hole 7 and the through hole 6, the threaded collar ring 4 is stationary relative to the screw 2 and does not drive the bearing plate 3 to rise or fall. One end of the outer wall of the limiting rod 8 is slidably sleeved with the through hole 6. Moving devices 9 are arranged at the four corners of the bottom of the bottom plate 1. Four connecting holes 10 are formed in a rectangular array on the upper surface of the bearing plate 3. Grooves 11 are provided on the side edges of the upper surface of the threaded collar ring 4, and the connecting holes 10 correspond to the grooves 11. When the limiting rod 8 is slidably sleeved with the connecting holes 10 and the grooves 11, the threaded collar ring 4 is stationary relative to the bearing plate 3. Therefore, when the screw 2 rotates, the threaded collar ring 4 drives the bearing plate 3 to rise;

[0024] Connecting rods 12 are fixedly connected to the four corners of the upper surface of the bottom plate 1. A protective plate 13 is fixedly connected to the tops of the four connecting rods 12. The protective plate 13 can not only limit the position of the screw 2, but also protect the topmost cartons. The top of the outer wall of the screw 2 is rotatably connected to the protective plate 13;

[0025] A motor 14 is fixedly connected to the bottom of the bottom plate 1. The output end of the motor 14 is drivingly connected with a main shaft. Four first wire wheels 15 are fixedly sleeved on the outer wall of the main shaft. The coordinated use of the four first wire wheels 15, the four belts 17 and the four second wire wheels 16 can make the four screws 2 rotate synchronously, so that the four threaded collar rings 4 drive the bearing plates 3 to rise uniformly. A second wire wheel 16 is fixedly sleeved on the bottom of the outer wall of the screw 2. A belt 17 is arranged between the second wire wheel 16 and the first wire wheel 15. The motor 14 is electrically connected to an external power supply through an external motor switch;

[0026] The mobile device 9 includes a fixed plate 91. The top of the fixed plate 91 is fixedly connected to the bottom plate 1. The bottom of the fixed plate 91 is rotatably connected to a turntable 92. The bottom of the turntable 92 is fixedly connected to a bracket 93. On one side of the bracket 93, connecting plates 94 are symmetrically and fixedly connected. A pin shaft 95 is fixedly connected between the two connecting plates 94. A roller 96 is rotatably sleeved on the outer wall of the pin shaft 95. The top of one side of the bracket 93 is rotatably connected to a brake plate 97, and the brake plate 97 can make the stacking device stationary.

[0027] The working principle of the present invention: When stacking cartons, first lift the brake plate 97, move the stacking device to the designated area, then press the brake plate 97 to fix the stacking device, then pull out the limiting rod 8 on the topmost threaded sleeve ring 4, insert it through the connection hole 10, and slidably sleeve it in the groove 11 on the threaded sleeve ring 4, and then stack the cartons neatly on the bearing plate 3;

[0028] When the topmost bearing plate 3 is full of cartons, turn on the motor switch, the motor 14 is powered on and works, and simultaneously drives the four screw rods 2 through the four first wire wheels 15, the four belts 17 and the four second wire wheels 16. Then the threaded sleeve ring 4 and the screw rod 2 rotate relative to each other, thereby driving the bearing plate 3 to rise. When the distance between the topmost bearing plate 3 and the bearing plate 3 of the lower layer is greater than the height of the carton, the motor 14 stops working, and then repeat the above steps to stack cartons on multiple bearing plates 3;

[0029] When the carton stacking is completed, lift the brake plate 97 and move the stacking device to the designated idle area.
