Description
Technical Field
[0001] This utility model belongs to the technical field of corrugated cardboard processing equipment, specifically relating to a bonding machine for corrugated cardboard processing. Background Technology
[0002] Corrugated cardboard, as a lightweight and high-strength packaging material, is widely used in various industries such as food, electronics, and logistics. Its core performance depends on the bonding strength and forming precision of the corrugated core paper and the linerboard. In the production process of corrugated cardboard, the bonding machine is the key equipment for achieving the lamination of the corrugated core paper and the linerboard. Its working efficiency and glue coating uniformity directly affect the product qualification rate and production cost.
[0003] Currently, corrugated cardboard bonding machines on the market generally suffer from the following problems: 1. The spacing adjustment mechanism of the embossing guide rollers is cumbersome to operate, lacks flexibility, and is difficult to adapt to corrugated core paper of different thicknesses and specifications. The adjustment process can easily damage the surface of the paper, affecting the appearance quality of the product. 2. The steering and guiding structure of some bonding machines is not well coordinated with the gluing and pressing mechanisms, which can easily cause deviation and wrinkles in the lamination process of corrugated paper and face paper, reducing the forming accuracy and dimensional stability of corrugated cardboard. At the same time, the gluing mechanism is poorly designed, often using a single glue roller or a fixed brush for gluing, resulting in uneven glue application, easy glue leakage and accumulation, which not only affects the bonding strength but also wastes glue and increases production costs.
