The laminating machine also operates independently, is provided with independent winding and unwinding equipment, a heating unit and a power system, and needs to unwind and laminate the preprinted raw paper roll. Lack organic connection between two independent equipment, unable continuous production leads to degree of automation low, and production efficiency is poor, and equipment area is big, and the energy consumption is high during the use.

Disclosure of Invention

The utility model discloses the problem that needs to solve is, current imprinter and laminating machine are independent each other, lead to unable continuous production to a preprinting line laminating equipment is provided, but makes preprinting and tectorial membrane twice technology continuous production, and production degree of automation improves greatly, and compression area practices thrift the energy consumption.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a pre-printing line laminating device comprises an unreeling unit, a printing unit, a laminating unit and a reeling unit, wherein base paper to be used is installed in the unreeling unit, and flows through the unreeling unit, the printing unit and the laminating unit in sequence; the film to be used is arranged in the film covering unit; the flow sequence of the finished product paper after film covering is a film covering unit and a winding unit.

In this technical scheme, the unit of unreeling, printing unit, the rolling unit that adopts all can use the current unit on the preprinting machine, and the tectorial membrane unit can adopt the current part in the laminating machine. The base paper to be used is generally installed in a roll in the unwinding unit and is discharged from the unwinding unit as required. The printing unit is used for preprinting the base paper. The film to be used is generally arranged in the film covering unit in a coiled manner, the compound surface of the film is covered with a pre-coating film, the pre-coating film is normally solid, and can be softened and liquefied after being heated, and the pre-coating film is fully infiltrated after being contacted with the base paper, so that the combination of the base paper and the film can be facilitated. In the laminating unit, after the composite surface of the base paper is contacted with the film through the pre-coating film, the base paper and the film are efficiently bonded without using glue, so that the number of equipment parts is reduced, and the process is accelerated. And collecting the finished product paper after film covering by the winding unit. In the whole equipment, because preprinting and film covering are integrated on the same production line, only the winding unit, the unwinding unit and the power unit of the preprinting machine need to be reserved, and the winding unit, the unwinding unit and the power unit on the traditional film covering equipment are abandoned. Compared with the traditional operation mode that preprinting and film covering are independent, the scheme reduces the winding and unwinding times and the turnover connection time between two devices; because the front and the rear processes are connected together, the secondary debugging is not needed during film covering, and the debugging time, labor and raw materials are saved; glue is not used in the film covering process, the total number of parts in the equipment is reduced, the investment cost of fixed assets is lower, and the occupied area is smaller; preprinting and film covering continuous operation share one set of winding and unwinding unit and power unit, and energy consumption is obviously reduced.

Preferably, a paper feeding tension unit is provided between the unwinding unit and the printing unit. The paper feeding tension unit is used for correcting the tension difference of two sides of the base paper, so that the base paper is not easy to be broken. This unit is a working unit inherent to the conventional preprinter.

Preferably, a dust removing device is provided between the paper feeding tension unit and the printing unit. The dust removal device is mainly used for removing dust, scraps and the like on the base paper, so that the surface of the base paper is clean, and a good composite effect is formed between the base paper and a film. The dust removing device is a common device in the manufacturing process of paper, paper products and the like, and the specific structure and the arrangement mode can be designed by those skilled in the art according to needs.

Preferably, an infrared light box is arranged at the downstream of the printing unit. The infrared lamp box is an inherent working unit of the traditional preprinter. In traditional imprinter, infrared lamp house is mainly used for solidifying the gloss oil in the printing ink, and in this scheme, infrared lamp house can also be used for heating the paper, makes the membrane of precoating with the compound face contact of paper soften the liquefaction fast, with the fine combination of body paper, makes the tectorial membrane effect in the tectorial membrane unit better.

Preferably, a paper discharge tension unit is provided between the infrared lamp box and the film covering unit. The paper outlet tension unit is also an inherent working unit of the traditional preprinter and is also used for correcting paper tension.

To sum up, the beneficial effects of the utility model are that: the two processes of preprinting and film covering can be continuously produced, the production automation degree is greatly improved, the occupied area is reduced, and the energy consumption is saved.
