An auxiliary device for three-dimensional compensation and cutting of banknotes

Abstract

In order to solve a series of cutting quality and appearance quality problems caused by the auxiliary platen of the cutter presser used in the existing printing system when it is used for paper products with uneven surfaces, the present invention provides a banknote The three-dimensional supplementary cutting auxiliary device is used to replace the auxiliary platen in the paper presser of the existing cutting machine. The invention breaks through the two-dimensional plane working mode of the auxiliary platen of the traditional paper presser. Through the metal integrated three-dimensional accurate compensation method, the surface of the substrate is designed to have different shapes, different levels, and different arrangement densities that match the concave and convex of the product. , low compensation layer, accurately realize point and surface relative fit pressure, increase local pressure under the same pressure, ensure that the working surface of the entire auxiliary device can compact the object to be cut, and ensure that it does not shift when it is cut. Effectively guarantee and improve the cutting accuracy, and the cutting quality is stable and reliable.

Description

technical field [0001] The invention relates to an auxiliary device for three-dimensional compensation and cutting of banknotes. Background technique [0002] The paper press of the cutting machine completes the pressing action before the cutting knife cuts into the banknote product, compresses the banknote product, and ensures that the banknote product remains stable under the action of the cutting force of the cutter, and does not undergo force displacement. It is the guarantee of the quality of cutting banknotes. Therefore, the performance of the paper press of the cutting machine plays a key role in the cutting quality of the banknote products. [0003] At present, the printing system adopts the German Bora cutting machine for banknote cutting production, and the working surface of its hydraulic paper press is a two-dimensional plane structure (such as figure 1 shown), for paper products with uneven surface (such as products with special gravure graphics), a deformable...
