[0002] Corrugated paper boxes, also known as corrugated paper boxes, cardboard boxes, larger ones are also called corrugated paper boxes, corrugated paper boxes, cardboard boxes, and sometimes simply cartons. They are boxes made of corrugated paper or pasted together, and are often used to package items for easy transportation. Corrugated paper is the basis for the production of corrugated paper boxes. Corrugated paper boxes are paper packaging containers made of corrugated base paper, core paper, boxboard and other roll materials through corrugating, gluing, drying, slitting, creasing, printing, slotting, nailing or gluing. Slitting and creasing machines are important processes in the production of corrugated paper.

[0003] The existing corrugated cardboard slitting and creasing machine can only perform single-board slitting and creasing, and cannot perform multiple slitting and creasing on the corrugated cardboard. At the same time, it is impossible to adjust the limit according to the slitting and creasing size of the corrugated cardboard, causing the corrugated cardboard to enter the machine body, and errors occur during slitting and creasing. The limitations are relatively large. For this reason, we provide a corrugated cardboard slitting and creasing machine that can perform multiple slitting and creasing on the corrugated cardboard to ensure the slitting quality of the corrugated cardboard.

[0012] 1. When the utility model is in use, the corrugated cardboard to be cut and indented is placed on the feeding plate and pushed into the machine body. The driving motor drives the conveying roller to rotate through the driving gear and the transmission gear, and then pushes the corrugated cardboard into the machine body. At this time, the electric push rod pushes the fixed frame down, and the rotating motor in each fixed seat drives the slitting knife to rotate through the sprocket and chain to cut the corrugated cardboard. The slitting knives are provided in several groups. The spacing between the slitting knives can be adjusted through the second electric guide rail and the movable seat, and the slitting knives are provided with several groups. If the quantity is more than one, multiple slitting can be performed. The slitting corrugated cardboard is transported by the conveyor roller until it reaches the surface of the conveyor belt. At this time, another electric push rod pushes the fixed frame down, and the longitudinal creasing wheel pair performs longitudinal creasing on the slitting corrugated cardboard. The reciprocating screw rod rotates to make the nut seat drive the moving frame and the transverse creasing wheel to move, and then the surface of the corrugated cardboard is transversely creasing, thereby completing the slitting and creasing work of the corrugated cardboard. In this way, the corrugated cardboard can be slid in multiple passes, and at the same time, the slitting corrugated cardboard can be creasing in the transverse and longitudinal directions.

A conveyor belt 19 is movably provided inside the machine body 1. A frame 7 is fixedly installed on the outside of the machine body 1. Two driving gears 5 are rotatably provided inside the frame 7. The driving gears 5 are connected to one set of shaft rods 3 one by one. The two driving gears 5 are kept in transmission through a transmission gear 6. A driving motor 8 is fixedly installed on the outside of the frame 7, and the output end of the driving motor 8 is fixedly connected to the driving gear 5. The corrugated cardboard is pushed from the feeding plate 2 into the machine body 1 and driven by the driving motor 8. The motor 8 drives the driving gear 5, which cooperates with the transmission gear 6 to drive the shaft 3 to drive the conveying roller 4 to rotate, and the conveying roller 4 conveys the corrugated cardboard into the body 1. After that, the electric push rod 9 pushes the fixed frame 10 to descend, so that the slitting knife 14 and the longitudinal creasing wheel 18 descend, and the corrugated cardboard can be cut and creasing. In addition, the second electric guide rail 11 can cooperate with the moving seat 12, and the moving seat 12 can move on the second electric guide rail 11 to adjust the distance between the two fixed seats 13, thereby adjusting the cutting size and creasing size of the corrugated cardboard. At the same time, a plurality of slitting knives 14 are arranged in the machine body 1, so as to perform multi-pass slitting on the corrugated cardboard; a rotating motor 15 is fixedly installed in each fixing seat 13, and a sprocket 16 is fixedly connected to the output end of the rotating motor 15 and one end of the rotating shaft of the slitting knife 14 and the longitudinal creasing wheel 18, and the sprockets 16 are driven by chains 17.

After that, the corrugated cardboard is placed on the feeding plate 2 and pushed into the machine body 1. The corrugated cardboard is transported into the machine body 1 by the conveying roller 4. Afterwards, the rotating motor 15 in the fixed seat 13 drives the slitting knife 14 and the longitudinal creasing wheel 18 to rotate through the sprocket 16 and the chain 17, and the fixed frame 10 is pushed down by the electric push rod 9, so that the corrugated cardboard can be cut and longitudinally creasing in multiple passes. In this process, the corrugated cardboard is transported to the surface of the conveyor belt 19. When the corrugated cardboard moves to the lower end of the transverse creasing wheel, the conveyor belt 19 and the conveyor wheel stop conveying, and the reciprocating screw rod 20 rotates, and the movable frame and the transverse creasing wheel are driven to move through the nut seat 21, so that the corrugated cardboard can be transversely creasing, and finally transported out of the machine body 1, the slitting and creasing of the corrugated cardboard are completed, and the corrugated cardboard can be folded.
