Description

Aluminized paperboard leveling device Technical Field The utility model relates to the technical field of paperboard processing equipment, in particular to an aluminized paperboard leveling device. Background Aluminized paperboard (also called aluminized paperboard or aluminum foil composite paperboard) is a material formed by compounding aluminum foil (or vacuum aluminized layer) with a paper base material, and has the flexibility of paper and the luster and barrier property of metal. It is widely used in the fields of packaging (such as food, medicine and cigarette box), decoration, labels and the like, and is favored because of the characteristics of beautiful appearance, moisture resistance, oxygen isolation, ultraviolet resistance and the like. Because the thermal expansion coefficients of the aluminum layer and the paper base are different, the expansion coefficient of aluminum is far higher than that of the paper base, when the ambient temperature changes (such as high temperature or drying condition), the contraction/expansion degree of the aluminum layer and the paper base are inconsistent, so that internal stress is unbalanced, and curling (bending to one side of the paper base is usually caused), in addition, in the process of manufacturing the packaging box by a manufacturer, the processing processes such as slitting, die cutting and the like can damage the structural balance of the materials, cause local stress concentration, cause curling, and meanwhile, if the rolled aluminized paperboard is not horizontally placed when being stored, the self weight can cause curling, and in order to ensure the product quality, a leveling device is needed to process the paperboard. The prior leveling device, for example, patent with publication number CN214164235U discloses a corrugated board leveling device, which is characterized in that a leveling plate and a base plate corresponding to the upper and lower positions are arranged on a supporting frame, the leveling plate is driven by a cylinder to press down to level a board, after the board is placed on the base plate for the board which is curled, when the leveling plate presses down, bending occurs again due to uneven stress of a bending part on the board and the board body, and the bending needs to be manually operated to level again, so that leveling efficiency can be affected.
