Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated paperboard production technical field more specifically, the utility model relates to a kind of paperboard hot pressing laminating machine. BACKGROUND

[0002] Corrugated paperboard is also called corrugated board or corrugated paperboard, which is a composite material made of one or more layers of corrugated core paper (also known as corrugated medium) and one or two layers of face paper (i.e. smooth paper). It is widely used in packaging of various products, especially transportation packaging, due to its lightweight, high strength, good cushioning performance and economic characteristics.

[0003] According to the number of layers of corrugated core paper, corrugated paperboard can be generally divided into single-layer corrugated paperboard, double-layer corrugated paperboard and multi-layer corrugated paperboard. In actual production, the corrugated paperboard after gluing and compounding will enter the hot press for pressing and molding. When the corrugated paperboard moves on the platform of the hot press, a hot press plate will be arranged above the platform to adhere to the corrugated paperboard, so as to apply a certain pressure to the upper and lower surfaces of the corrugated paperboard and transfer heat. Since the hot press directly contacts the upper and lower surfaces of the corrugated paperboard through the platform and the hot press plate to transfer heat, and due to the existence of corrugation, there is a certain gap between adjacent face papers, therefore, when hot pressing the multi-layer corrugated paperboard, the corrugated core paper at the middle position receives less heat than the corrugated core paper at the outer layer, resulting in uneven heating of the entire corrugated paperboard, which further affects the molding quality of the corrugated paperboard.

[0024] In the embodiment, the specific implementation scenario is that after the corrugated board 3 is laminated by the laminating mechanism, the corrugated board 3 is continuously moved to the hot-pressing mechanism 2 by the subsequent traction mechanism for hot-pressing and shaping. When the multilayer corrugated board 3 is hot-pressed, it is difficult for the heat provided by the upper hot-pressing plate 214 and the lower hot-pressing box 221 to be transmitted to the corrugated core paper located at the middle position.
