[0036] After the carton is folded, the first motor 15 is started, and the second motor 15 drives the second synchronous wheel 28 to rotate through the transmission belt 17, thereby driving the second connecting block 26 to rotate and rotate the originally horizontal carton 8 to a vertical state, and then the third electric push rod 11 is started to push the carton 8 to the top of the folding table 2, and then the third motor 18 is started to make the carton 8 tilt clockwise at a certain angle, and then the carton is moved down again so that the folding plates at the bottom of the unfolded carton contact the bending rod 3 and the top of the folding table 2, and after the carton continues to move downward, the folding plates on both sides will be folded to the bottom of the carton, making it level with it, and When the box moves down and is folded, the No. 3 motor 18 can be started again to restore the originally tilted grabbing plate 8 to a vertical state.

When folding, the distance between the two bending rods 25 can be adjusted by starting the No. 4 motor 6 so that the bending rod 25 can adapt to cartons of different widths. When folding the cartons, the flat cartons will be placed on the placement table 7 in advance, and then the grabbing plate 8 will move down under the push of the No. 1 electric push rod 13, and absorb the four sides of the cartons through the suction cup 19, and then lift the grabbing plate 8. At this time, the cartons will unfold under the action of gravity, and then start the No. 2 motor 15. The No. 2 motor 15 can drive the No. 2 synchronous wheel 28 to rotate through the transmission belt 17, and then Drive the No. 2 connecting block 26 to rotate and rotate the originally horizontal grabbing plate 8 to a vertical state, then start the No. 3 electric push rod 11 to push the grabbing plate 8 to the top of the folding box table 2, then start the No. 3 motor 18 to tilt the grabbing plate 8 clockwise at a certain angle, then move the grabbing plate 8 downward so that the folding plate at the bottom of the unfolded carton contacts the bending rod 3 and the top of the folding box table 2, and after the carton continues to move downward, the folding plates on both sides will be folded to the bottom of the carton, making it horizontal with it, and while the carton is moving downward and folding, the No. 3 motor 18 can be started again to make The originally tilted grabbing plate 8 returns to a vertical state, and the above two steps need to be performed simultaneously. At this point, the folding plates on both sides of the bottom of the carton can be folded. Then start the No. 2 electric push rod 10, pull the grabbing plate 8 to move horizontally, so that the carton slides on the folding box table 2, and when sliding to the middle, the other two folding plates at the bottom of the carton will contact the bending rod 25, and fold with each other under the restriction of the bending rod 25 and be horizontal with the bottom of the carton. At this time, the folding of the carton can be completed, and the folded carton will be pushed to the sliding table 4 for the next operation.
