Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboard processing, in particular to a corrugated paperboard flattening device. Background Art

[0002] Corrugated paper is a material that is made by pressing wrinkles and waves into glossy paper using corrugated rollers, while corrugated cardboard is a thickened panel made by pasting multiple groups of corrugated paper together. It is lightweight and has a correspondingly improved structural strength. However, after pasting the panels on the outside of the central paper, it is often necessary to use a flattening device to process it again in order to keep it flat.

[0003] However, ordinary flattening devices often limit the height of each roller, while the thickness of each corrugated cardboard is different. When pressing, it is necessary to disassemble and reassemble according to the position of the board, which is very inconvenient. In addition, the pressing strength is different, making it difficult to maintain the uniform flatness of the cardboard after pressing.

[0004] Now, a novel corrugated board flattening device is proposed to solve the above problems. Utility Model Content

Five groups of windows 24 are arranged between the top and bottom of the top plate 10, and a sleeve block 21 is fixed to the top of the window 24. Sliding beads 22 are movably embedded on both sides of the sleeve block 21, and an indicator label 19 is fixed between the two sides of the front end of the window 24.

Because the central slot hole inside the large toothed disc 16 has a thread, it can match the outer wall of the screw rod 15. When the large toothed disc 16 rotates, the screw rod 15, the pressing block 11 and the pressing roller shaft 12 in the circular groove 27 are vertically lifted and lowered under the restriction of the guide rods 14 embedded in the jacks 13 on both sides, forcing the pressing roller shaft 12 to approach the electric roller shaft 3 at the bottom, and make adjustments to the pressing according to the different thicknesses of the corrugated cardboard.
