Description

Drying system after bill printing

Technical Field

The application relates to the field of paper drying, in particular to a drying system used after bill printing.

Background

The bill as a voucher usually has a certain economic value, so that the bill is required to have a long storage time when the anti-counterfeiting printing treatment is performed. In order to enable some high-value bills to have long storage time, curing agents need to be sprayed on the surfaces of the printed bills immediately, so that the storage time of the bills is prolonged.

The existing bills can be matched with a heating device by a fan after the curing agent is sprayed, such as an electric heating wire and the like, hot air is blown out of the surfaces of the bills, and the bills coated with the curing agent on the surfaces can obtain a rapid drying effect.

To the above-mentioned correlation technique, the inventor thinks that the bill surface that just has coated is wet, uses the fan to blow to the bill surface this moment, can make more dust in the air or some other impurity adhesion on the bill surface for the surface adhesion is more dust impurity after the bill is dried, has the defect that bill surface quality receives the influence.

Disclosure of Invention

In order to reduce the influence that bill surface quality received, this application provides a drying system after bill printing.

The application provides a drying system after bill printing adopts following technical scheme:

the utility model provides a drying system after bill printing, is including supplying the stoving case that the bill of coating the curing agent got into, the stoving incasement is equipped with the laminating in order to carry out the array stoving roller of drying to the bill in the bill both sides surface, and the stoving roller is equipped with along self rotation direction towards bill pivoted one side and cleans the portion, cleans the portion and hugs closely in the stoving roller surface, and stoving case supplies bill entering one side to be equipped with the dust removal passageway that the bill after supplying the curing agent coating carries out the transmission in inside, is equipped with the electrostatic generator that can adsorb dust impurity in the dust removal passageway, and the one side that the dust removal passageway was kept away from to the stoving incasement is equipped with a set of power roller that drives the bill antedisplacement.

Through adopting above-mentioned technical scheme, the bill passes through the dust removal passageway after the coating curing agent and enters into to the stoving incasement, the electrostatic generator in the dust removal passageway can reduce the bill as far as possible and be infected with the possibility of dust at the in-process that gets into the stoving case, then the bill passes through each stoving roller of group again, with drying, and before each side rotation contact in the bill at each stoving roller, the portion of cleaning can clean with the stoving roller surface earlier, make the stoving roller surface comparatively clean, reduce the stoving roller and directly press the dust to the bill on, reduce the bill surface and receive the possibility of polluting, help the promotion of bill surface quality.
