Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard production, in particular to conveying equipment for a corrugated cardboard production line. Background Art

[0002] Corrugated paper is a sheet made by gluing together liner paper and corrugated paper formed by corrugating rollers. The corrugated paper has concave and convex grooves, which give the corrugated board a certain thickness, making it lightweight and saving raw materials. Furthermore, the concave and convex grooves also form reinforcing ribs, increasing the strength of the corrugated board. Corrugated board generally consists of a bonded upper skin, at least one middle layer of corrugated paper, and a lower skin. When making corrugated cardboard boxes, a further layer of box packaging is bonded to the upper skin. Due to the concave and convex structure of the corrugated paper, appropriate pressure must be applied after gluing to ensure a firm bond between the layers. Therefore, a certain amount of pressure is often applied during the transportation of the corrugated board.

During the cardboard conveying process, foreign particles may adhere to the surfaces of the conveyor belt and the pressure belt. During the cardboard conveying process, the high pressure exerts a certain downward pressure on the cardboard on the conveyor belt. The foreign particles adhered to the conveyor belt, pressure belt or pressure roller may cause damage to the surface of the corrugated cardboard. Utility Model Content
