[0025] The output shaft of the motor 208 is fixedly connected to a bevel gear 207, and the outer surface of the bevel gear 207 is meshed with two bevel gears 1 206. The outer surface of each bevel gear 1 206 is fixedly connected to a connecting rod 205.

At the same time, the telescopic rod 15 can prevent the spring 9 from exceeding the elastic limit. When the spring 9 contracts, it will be retracted into the cutting knife 6, so that the cutting knife 6 can cut the paper box.

[0034] Working principle: When the paper box needs to be flattened, the paperboard is placed on the base 1, and the screw 1 8 is rotated to drive the limiting plate 2 311 to descend. The limiting plate 2 311 drives the sliding block 307 to slide downward at the same time. When the sliding block 307 slides downward through the support column 308, it presses the hinge rod 304 downward. The hinge rod 304 will distribute a horizontal force to the positioning bar 301 through the hinge, thereby pushing the positioning bar 301 to move. At the same time, the telescopic rod 2 305 will extend with the movement of the positioning bar 301 until the positioning bars 301 on both sides tighten the paperboard. At the same time, the two The positioning bar 301 drives the smoothing roller 210 to extend and retract, and then the lifting screw 314 is rotated to drive the smoothing groove 312 to descend, and the smoothing roller 210 descends to the intersection of the limiting groove 303 and the smoothing groove 302, and the motor 208 is started. Then the smoothing roller 210 slides in the smoothing groove 302 to achieve the effect of smoothing the paper box, and the connecting block 11 is started.

Through the above, paper boxes of different sizes can be flattened.
