Method and device for adding anti-counterfeit material in papermaking process

Abstract

The invention discloses a method and a device for adding an anti-counterfeit material in a paper manufacturing process. According to the method, the anti-counterfeit material is added into an internet-like manufacturing process by equipment which can regulate and measure the size of the added anti-counterfeit material, so that the regulation of addition amount of different products is realized, the aim of adding the material stably and continuously is achieved, the anti-counterfeit material can be saved to the maximum extent, and the scrubbing difficulty is lightened. The method for adding the anti-counterfeit material is ingenious in design, and the device for adding the anti-counterfeit material has a simple structure and multiple control means; moreover, the aims of continuity, stability and regulation of the added anti-counterfeit material can be achieved.

Description

technical field [0001] The invention belongs to the technical field of paper anti-counterfeiting, and particularly relates to a method for adding anti-counterfeiting materials in a paper-making process and an adding device thereof. Background technique [0002] like figure 1 As shown, it is a papermaking process used by many domestic paper mills to manufacture paper with anti-counterfeiting materials. Specifically, the anti-counterfeiting materials and water are firstly added to the dilution tank 16 and stirred, and then the stirred liquid is added to the front pool 17. Then, it is processed by the papermaking tank 18, the slag remover 19, and the pressure screen 20 in sequence, and then sent to the Internet tank 7 through the pipeline for Internet papermaking. The above process mainly has the following shortcomings: [0003] 1. The anti-counterfeiting materials currently used in China, such as special fibers, fluorescent balls, security sheets, etc., are all paper or PET ...

AI Technical Summary

Problems solved by technology

[0005] 3. After the anti-counterfeiting material is added, the pipeline process is long, and it needs to go through slag removal and screening before going online. Some anti-counterfeiting materials will be discharged along with the tailings, resulting in the loss of anti-counterfeiting materials

[0006] 4. Because some anti-counterfeiting materials, such as security sheets, are made of paper, they cannot withstand the high-intensity shearing force of agitators, slurry pumps and soaking in slurry for a long time, and some anti-counterfeiting materials will be damaged and lose their anti-counterfeiting properties. function, thereby affecting the use of anti-counterfeiting materials
