Abstract

The invention relates to a thermoformed sheet and printed film lamination device and a production method. The lamination device comprises supporting wall plates, a printed film unwinding mechanism, a gluing mechanism, a drying mechanism, a laminating mechanism, a sheet unwinding mechanism and a winding mechanism, wherein the printed film unwinding mechanism, the gluing mechanism, the drying mechanism, the laminating mechanism, the sheet unwinding mechanism and the winding mechanism are respectively mounted on the supporting wall plates, and the printed film unwinding mechanism, the gluing mechanism, the drying mechanism, the laminating mechanism, the sheet unwinding mechanism and the winding mechanism are arranged in sequence according to a printed film processing sequence. The thermoformed sheet and printed film lamination device is characterized in that the gluing mechanism comprises a glue tank, a glue smooth roll, a glue transitional roll, a glue press roll and a pneumatic cylinder, the glue smooth roll is immersed in the glue tank, the glue smooth roll, the glue transitional roll, the glue press roll and the pneumatic cylinder are sequentially connected from bottom to top, and a piston rod of the pneumatic cylinder is connected to the glue press roller. The lamination device can be used for realizing the diversity of surface hues of a thermoformed sheet, increasing the attractiveness of the thermoformed sheet and improving the quality of film lamination.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a thermoforming sheet and printing film lamination device and production method. Background technique [0002] In order to make the surface of printed matter such as pictures, product brochures, packaging boxes, drawings and labels more beautiful, and waterproof and wrinkle-resistant, a protective film is usually coated on the surface of the printed matter. The technology of coating this protective film is called lamination technology. . The existing laminating machine generally includes a film supply device, a glue roller, a heating and drying device, a hot pressing roller, a pressure roller, a paper supply device and a plurality of guide rollers. The roller is coated with a layer of glue with a certain thickness, and then the glue on the film is semi-dry through the heating and drying device, and then the printed matter with the printed text or pattern and the fi...
