[0002] Corrugated cardboard boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging products. Due to their superior performance and excellent processing properties, corrugated cardboard boxes have gradually replaced wooden boxes and other transport packaging containers, becoming the mainstay of transport packaging.

[0003] During the production of corrugated boxes, a creasing machine is needed to press creases into the folded areas of the corrugated cardboard. However, current creasing machines apply pressure to the corrugated box during creasing to hold it in place, but cannot buffer the downward pressure on the corrugated box, which may cause damage to the surface of the corrugated box. Therefore, those skilled in the art have provided a creasing machine for corrugated box production. Utility Model Content

The top ends of the two sliding rods 18 are fixedly connected to a lifting plate 9. A threaded hole 12 is opened on the upper surface of the lifting plate 9. A motor 13 is installed on the upper surface of the top plate 7. A threaded rod 10 is fixedly connected to the output end of the motor 13. The top end of the threaded rod 10 passes through the threaded hole 12 and extends to the top of the lifting plate 9. A connecting plate 14 is fixedly connected to the bottom end of each sliding rod 18. Two fixed cylinders 5 are fixedly connected to the bottom surface of each connecting plate 14. A spring 23 is fixedly connected to the inner wall of each fixed cylinder 5. A connecting column 15 is fixedly connected to the bottom end of each spring 23. A pressure plate 4 is fixedly connected to the bottom end of each set of connecting columns 15.

[0023] Two connecting plates 14 are fixedly connected to two fixed plates 20 on their adjacent sides. A control mechanism 22 is installed on the adjacent sides of the two fixed plates 20. A pressure wheel body 21 is installed on the outer surface of the control mechanism 22. The control mechanism 22 consists of a motor and a lead screw. The pressure wheel body 21 is installed on the lead screw. The motor drives the lead screw to rotate, and the pressure wheel body 21 moves to complete the pressure work. Two reinforcing rods 6 are fixedly connected to the outer surface of each connecting plate 14. The top of each set of reinforcing rods 6 is fixedly connected to the outer surface of each sliding rod 18. The reinforcing rods 6 can connect the sliding rod 18 and the connecting plate 14, enhancing the stability of the connecting plate 14. A limiting plate 11 is provided above the top plate 7.

[0025] The working principle of this utility model is as follows: When in use, first place the corrugated carton on the protective pad 2, then start the motor 13. The motor 13 will drive the threaded rod 10 to rotate inside the threaded hole 12, and the lifting plate 9 will slide on the threaded rod 10. At the same time, the slide rod 18 will push the connecting plate 14 down until the pressure roller body 21 contacts the corrugated carton. At this time, the pressure plate 4 will press the corrugated carton, and the connecting column 15 will squeeze the spring 23. The spring 23 will contract, and the force of the connecting column 15 on the pressure plate 4 will be buffered to a certain extent, which can avoid damage to the corrugated carton. Finally, start the control mechanism 22, and the pressure roller body 21 will move left and right to complete the pressure work.
