Problems solved by technology

[0002] In recent years, with the rapid development of the bill business, some lawbreakers have created counterfeit bills by cloning and altering bills, which not only caused heavy economic losses to the country, but also affected the stability of the financial order.
Among the counterfeit bills, ordinary bills (such as tax bills) have become the main forgery objects, but since the anti-counterfeiting digital is only printed on the surface of the paper, it is easy to be forged, so the original inquiry digital anti-counterfeiting label can no longer adapt Management Identification Requirements for Current Bills

Embodiment Construction

[0017] The following describes the implementation of the present invention in detail with reference to the drawings and embodiments.

[0018] Take the code "2012" as an example to further illustrate the present invention.

[0019] See figure 1 The modern papermaking process includes pulping in a pulp tank, then forming a line on the wire section of the papermaking equipment, and then sending it to the paper winder after being pressed and dried. The digital encryption method of the fiber papermaking process of the present invention is used in modern papermaking. The following processes are added to the process:

[0020] First, during the pulping process, 30% of the pulp weight of magnetic fiber is added and mixed evenly;

[0021] The magnetic fiber can be Fe3O4, Fe2O3, CrO2 or trivalent iron oxide with cobalt added to iron oxide.

[0022] Second, cover a layer of partition 2 on the mesh of the papermaking equipment. A slide rail 3 is arranged above the partition 2 along the pulp flow di...

Abstract

The invention discloses a digital encryption method for a fiber papermaking process, characterized by in pulping process, adding magnetic fibers to mix uniformly; and in the process that the pulp flows, controlling magnetic fiber with coding effect on the pulp by using a magnetic coding controller. The magnetic coding controller is arranged above the wet section, comprises an input module, a conversion module, a storage module, and a processing module, the input module is connected with the conversion module for inputting decimal numbers, the conversion module is connected with the storage module to convert the input numbers into 8421 coding, and the processing module is connected with the storage module for controlling the magnetic properties of the bar codes on a magnetic encoder; the coding area of the magnetic coding controller is rectangular, the width is equal to the width of a paper web, the bar codes are equispaced in the coding area, the magnetic encoder controls the magnetic properties of each magnetic stripe through electricity, and when the pulp flows through the coding control area, magnetic fibers in the pulp gather below the separator plate corresponding to the magnetic controller under the effect of magnetic field, thus magnetic bar codes are formed in the interior of the paper.

Description

Technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a digital encryption method for fiber paper-forming process. Background technique [0002] In recent years, with the rapid development of the bill business, some criminals have used methods such as cloning and altering bills to create counterfeit bills, which not only caused major economic losses to the country, but also affected the stability of the financial order. Among the counterfeit bills, ordinary bills (such as tax bills) have become the main objects of forgery. However, since the anti-counterfeiting digital is only printed on the surface of the paper, it is easy to be forged, so the original query digital anti-counterfeiting label can no longer be adapted Current management identification requirements for bills. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to p...
