[0031] Working principle:

[0032] The first step is to start the driving motor 6 when different specifications of paper boxes need to be produced. The driving motor 6 drives the threaded rod 37 to rotate. Since the outer wall of the threaded rod 37 is provided with a left-handed thread 371 and a right-handed thread 372, the sliding plate 35 threadedly connected to the threaded rod 37 can move closer to or farther away from each other along the second sliding rod 43. The movement of the sliding plate 35 drives the rotating push block 34 fixedly connected to the sliding plate 35 to move. The rotation drives the angle between the two stretching rods 33 hinged by the rotating push block 34 to change, thereby driving the stretching rod 33 to move closer to or farther away from each other. The angle between the two push rods 31 hinged at 33 changes, so that the push rod 31 drives the push block 36 to move horizontally, and the push block 36 moves along the push groove 421 on the lower template 42, so that the distance between the two lower templates 42 changes, until the distance between the two lower templates 42 is the same as the bottom surface of the paper box to be processed, and then a bottom plate 9 with the same bottom surface as the paper box to be processed is placed on the vertical limiting plate 422 of the lower template, and the two side surfaces of the bottom plate 9 are close to the side surfaces of the horizontal limiting plate 423, so that the bottom plate 9 is stably clamped;

[0033] The second step is to fix the top plate 8 that matches the top of the paper box to be processed and formed with the connecting plate 7 through bolts, and then place the cardboard with the indentation on the two lower templates 42, start the second electric telescopic rod, and the second electric telescopic rod drives the top plate 8 to move downward, so that the top plate 8 squeezes the paper box, and then start the second electric telescopic rod, and the second electric telescopic rod drives the side plate 52 to squeeze the paper box, so that the forming of the paper box is completed. At this point, the entire workflow is completed.
