Embodiment Construction
[0026] The implementation mode of the present invention is illustrated by specific specific examples below, and those who are familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this description. Obviously, the described embodiments are a part of the present invention. , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0027] It should be noted that the paper produced by the cardboard production line in this embodiment is divided into three pulp layers: the surface paper layer, the core paper layer and the bottom paper layer. And the technical scheme of the middle layer of the backing paper layer. "Water" is a commonly used term in the papermaking industry, and it is usually the reusable water that comes off d...

A paperboard information element metering and feeding system is characterized in that a discharge port of an information element bin is connected with a continuous metering device, and the continuous metering device is connected with an information element dispersing and homogenizing device through a feeding pipeline; a water tank is connected with an element adding water pipeline, the element adding water pipeline is connected with the upper part of an information element dispersing and homogenizing device through a water pump, and the lower part of the information element dispersing and homogenizing device is connected to the water tank through an element slag flowing water pipeline; the side part of the information element dispersing and homogenizing device is communicated with an information element isobaric distribution device; the side part of the information element isobaric distribution device is connected with an information element release pipeline; the tail end of a pseudo element release pipeline is communicated with a water curtain release device; and an opening of the water curtain release device faces the paper surface of a card paper forming net. According to the method, the problem of directionally and quantitatively adding the information elements in the anti-counterfeiting paper is solved, the controllability of adding the information elements and low and even no damage to the paper surface are realized, and the approximate quantity (density) in the paper by taking the square centimeter as the unit can be controlled.
Description
technical field [0001] The invention relates to the technical field of papermaking, in particular to a metering and feeding system for paper jam information elements. Background technique [0002] In view of the fact that the widely used anti-counterfeiting paper is to add anti-counterfeiting markers to paper, for example, adding anti-counterfeiting fiber to banknote paper is a typical representative of this kind of anti-counterfeiting paper. Most of the anti-counterfeiting markers added to the anti-counterfeiting paper are randomly distributed on the paper surface. In view of the existing banknotes and tickets for major events, the anti-counterfeiting markers added to the anti-counterfeiting paper are irregular and full-page added. It is not determined which layer of the pulp is randomly distributed inside the paper. The purpose is only to look at the paper. Whether it contains anti-counterfeiting markers, the information element described in the present invention is based...
