Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when applying the above-mentioned technical solutions to the process of producing coated aluminum foil composite paper, it is necessary to finish coating one or both sides of the cardboard first, and then carry out the aluminum foil coating operation. After setting up in this way, the laminating machine and the laminating machine are arranged in the workshop in sequence, which occupies a large space, and the laminating paper after the lamination is completed and cooled and shaped needs to be preheated to cooperate with the glue coating in the aluminum foil coating operation. The hot pressing process undoubtedly causes a waste of energy, which is not conducive to the implementation of environmentally friendly production

Abstract

The invention relates to a paperboard laminating aluminum foil compounding process and a compounding machine thereof. The compounding machine comprises a base, wherein an unwinding part, a laminatingpart, a cooling part and a winding part are sequentially arranged on the base. An aluminum foil unwinding roller, a gluing device and a hot pressing roller are arranged on a machine shell. The upper end of the machine shell is rotationally connected with two supporting rollers. The laminated paperboard cooled by a cooling roller keeps a certain heat degree and is lapped above the two supporting rollers. The gluing device is located above the position between the two supporting rollers. The hot pressing roller is located over the supporting roller away from the unwinding part. An adjusting device used for adjusting the abutting degree of the hot pressing roller and the supporting rollers is arranged on the machine shell. A drying device is arranged on the side, away from the unwinding part,of the machine shell, and the cooling part is arranged between the drying device and the winding device. According to the invention, the laminated paperboard with certain heat and the aluminum foil penetrate through the space between the hot-pressing roller and the supporting rollers together to be subjected to hot-pressing compounding, the firmness and stability of the laminated aluminum foil composite paperboard can be improved, heat energy loss is reduced, and the laminated aluminum foil composite paperboard is more environmentally friendly in the production process.

Description

technical field [0001] The invention relates to the technical field of composite production of coated paper, in particular to a composite process of cardboard coated with aluminum foil and a composite machine thereof. Background technique [0002] In the production process of paper cup paper bowl paperboard, a layer of PE film is usually poured on one or both sides of the paperboard to improve the waterproof performance of paper cup paper bowl, but the heat resistance is not good, and it may be used in some high-end restaurants. In the high-temperature tableware, it is even necessary to cover the inner wall or inner and outer walls of the paper cup and paper bowl with aluminum foil. On the one hand, it can increase the heat preservation and high temperature resistance of the paper cup and paper bowl, and on the other hand, it also improves the high-end feeling of the paper cup and paper bowl. In the production of coated aluminum foil composite paper, existing manufacturers u...
