Description

Technical Field

[0001] The utility model relates to the field of laminating equipment, in particular to a laminating mechanism of a laminating machine. Background Art

[0002] The existing laminating mechanism includes a frame, in which a heating roller and a pressure roller arranged below the heating roller are rotated inside the frame, a rubber layer is laid on the surface of the pressure roller, and sliders are respectively provided at both ends of the pressure roller for rotation, and each slider is respectively provided with a driving cylinder or an oil cylinder. The driving cylinder or the oil cylinder drives the slider to drive the pressure roller to move closer to or away from the pressure roller, thereby adjusting the distance between the heating roller and the pressure roller so that the film and the substrate can pass through for lamination. The heating roller rotates actively. When the film and the substrate pass between the pressure roller and the heating roller, the pressure roller is driven to rotate by the substrate. In the above mechanism, if the speed of the film and the substrate passing through is fast, that is, the speed of the pressure roller is fast, the middle part of the rubber layer laid on the surface of the pressure roller is deformed by the centrifugal force generated by the high-speed rotation of the pressure roller, thereby forming a cavity between the rubber layer and the surface of the heating roller. The cavity cannot generate a pressing force on the film and the substrate, resulting in lamination failure. Therefore, due to the above defects, the heating roller and the pressure roller of the existing laminating mechanism cannot rotate at a high speed, resulting in a slow passing speed of the film and the substrate and low lamination efficiency.
