Description

Technical Field

[0001] The utility model relates to the field of printing and packaging processing, in particular to a pressing mechanism of a printing and packaging compound machine. Background Art

[0002] A laminating machine is a machine that bonds two or more layers of materials together with adhesive to give the original materials new functions. Films, aluminum foils, films, paper, non-woven fabrics, etc. are often used. In the field of food packaging, it is necessary to apply packaging film to the outer packaging. In this case, a laminating machine is needed to press the multi-layer film into a composite film before the packaging process.

[0003] The search publication number is: CN218701284U. A printing and packaging compound machine laminating mechanism comprises a workbench, wherein a lower pressing roller and an upper pressing roller are movably connected to the inner side of the workbench, and an adjusting component is arranged between the upper pressing roller and the workbench, and the adjusting component comprises connecting columns fixedly installed on both sides of the upper pressing roller, and the other end of the connecting column is fixedly and movably connected to a mounting seat. By setting the adjusting component, the user manually rotates the fastening seat, and under the cooperation of the threaded hole and the threaded rod, the rubber pad is disengaged from the second column, and under the cooperation of the fixed rod and the sliding seat, the distance between the upper pressing roller and the lower pressing roller can be horizontally adjusted, so that materials of different thicknesses can be pressed. However, the application has the following shortcomings: the distance between the upper pressing roller and the lower pressing roller is adjusted by manually rotating the fastening seat, and the thickness of the material is different. Manual control cannot accurately adjust the distance between the upper pressing roller and the lower pressing roller to close the material to achieve pressing. Therefore, a printing and packaging compound machine laminating mechanism is proposed. Utility Model Content
