Description

Technical Field

[0001] This utility model relates to the field of corrugated paper technology, specifically to a corrugated cardboard slitting and pressing device for carton production. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper together. It is mainly used to manufacture packaging containers and has the characteristics of low cost, light weight, high strength and recyclability. However, a corrugated paper slitting and cutting device is required in the corrugated paper processing.

[0003] In response, Chinese patent application number CN218804281U discloses a corrugated cardboard creasing device, including a base, with mounting frames fixedly connected to both sides of the upper surface of the base. Threaded rods are provided inside the two mounting frames, with the bottom ends of the two threaded rods rotatably connected to the bottom wall of the mounting frames. The top ends of the two threaded rods pass through the top wall of the mounting frames and are connected to a drive motor. Threaded sleeves are threadedly connected to the outer sides of the two threaded rods, and each threaded sleeve has a vertically inserted limiting rod, the bottom end of which is fixedly connected to the bottom wall of the mounting frames. In this invention, starting the drive motor causes the threaded rods to rotate, which in turn drives the threaded sleeves to move up and down, thereby causing the upper creasing roller to move up and down. This allows adjustment of the distance between the upper and lower creasing rollers. When creasing corrugated cardboard of different thicknesses, there is no need to disassemble and reassemble the upper creasing roller, saving time and effort. Furthermore, the included collecting device ensures neat and orderly collection of the corrugated cardboard.
