Description

Three-dimensional difference compensating and cutting auxiliary device for paper money

Technical Field

The invention relates to a three-dimensional difference complementing and cutting auxiliary device for a banknote.

Background

The paper pressing device of the cutting machine completes the pressing action before the cutting knife cuts into the paper money products, compacts the paper money products, ensures that the paper money products are kept stable under the cutting force of the cutting knife without stress displacement, and guarantees the quality of the cut paper money products. Therefore, the performance of the paper pressing device of the cutting machine plays a critical role in the cutting quality of the money products.

At present, a printing system adopts a German Bola guillotine to cut banknotes, the working surface of a hydraulic paper weight is of a two-dimensional plane structure (as shown in figure 1), and aiming at paper products with uneven surfaces (such as products with special gravure pictures and texts), a deformable plane auxiliary pressing plate can be adopted to compensate the pressure area, but the auxiliary pressing plate cannot compact the products, at the moment, the product is buckled (sitting alive), and batch waste products can be cut when the buckling is serious; meanwhile, a series of cutting quality and appearance quality problems such as rough edges of the surface, prominent smearing of watermarks, unsmooth edges and the like occur.

Disclosure of Invention

The invention provides a three-dimensional difference complementing and cutting auxiliary device for a banknote, which is used for replacing a secondary pressing plate in a paper pressing device of an existing guillotine, and aims to solve a series of cutting quality and appearance quality problems caused when the secondary pressing plate of the paper pressing device of the existing guillotine, which is adopted in an existing printing system, is used for paper products with uneven surfaces.

The technical scheme of the invention is as follows:

a three-dimensional difference complementing and cutting auxiliary device for paper money is characterized in that: the paper pressing device comprises a base plate, a first compensation layer and a second compensation layer which are arranged on the base plate, and two fastening hooks which are respectively arranged on two sides of the side of the base plate and are used for installing the whole auxiliary device below a paper pressing device;

the first compensating layer is arranged on one side of the upper surface of the substrate and extends along the length direction of the substrate;

the second compensating layers are arranged on the other side, opposite to the first compensating layer, of the upper surface of the substrate and distributed at intervals along the length direction of the substrate; the number and the position of the second difference supplementing layers are matched with white edges, close to the cutting opening, on the multiple bundles of cut banknote products which are placed side by side, so that the white edges of the multiple rows of cut banknote products are simultaneously matched and pressed;

each second difference compensating layer is connected with the substrate through a transition region;

the substrate, the first difference compensating layer, the second difference compensating layer and the transition region jointly form a working surface of the whole auxiliary device;

the base plate is used for pressing the convex structure on the cut banknote product; the first difference compensating layer is used for compressing and tensioning the cut banknote products during cutting; the second difference compensating layers are respectively used for simultaneously pressing the white edge parts on the stacked cut banknote products which are arranged side by side; the transition area is used for pressing the transition area of the convex structure and the concave structure on the cut currency products.

Further, the roughness of the working surface was 3.2.

Further, the width of the second difference compensating layer is smaller than the width of the white edges of the four sides of the cut banknote product.

Further, it is characterized in that: the width of the base plate is smaller than that of a single cut banknote product.

The invention has the advantages that:

1. the invention breaks through the two-dimensional plane working mode of the secondary pressing plate of the traditional paper pressing device, designs the high and low difference-compensating layers with different shapes, different high and low levels and different arrangement density sizes which are matched with the concave-convex of a product on the surface of the substrate through a metal integrated three-dimensional accurate difference-compensating method, accurately realizes the matching pressure application of point and surface, improves the local pressure under the same pressure, ensures that the working surface of the whole auxiliary device can compact a cut object, ensures that the cut object does not displace when being cut, effectively ensures and improves the cutting precision, and has stable and reliable cutting quality.

2. The transition area is designed between the second difference compensating layer and the substrate, so that excessive indentation and even breakage of the banknote product due to pressure during cutting are avoided.

3. By reasonably selecting the roughness of each working surface of the auxiliary device, on the basis of ensuring enough friction force, the printing ink has certain smoothness, thereby ensuring that printing ink particles are not transferred due to damage to printing image-text prints, avoiding the occurrence of the phenomenon of sticking dirt in periodic mass production and improving the appearance quality of products.

4. The paper pressing device can be safely and stably arranged below the existing paper pressing device (such as the paper pressing device of a Bola 115 type cutting machine) to work through the hooks on the left side and the right side, is convenient to disassemble and assemble, cannot run and wear during long-term cutting production, and ensures stable improvement of cutting quality.

5. The invention is very convenient and fast when the banknote products of different varieties need to be cut and converted, eliminates the hidden danger of cutting quality and improves the working efficiency.

6. The invention fills the technical blank that fine printed matters (such as paper with special anti-counterfeiting materials and paper caused by intaglio printing and embossing, intensive bank notes and tickets with large height and fall, and the like) cut by the Pola 115 type cutting machine have high requirements on the cutting quality, and lays a foundation for the cutting quality control of new products subsequently developed.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 2, the three-dimensional difference compensating and cutting auxiliary device for banknotes provided by the present invention comprises a substrate 1, a first difference compensating layer 2 (or called a pressing protrusion) disposed on the substrate 1, a second difference compensating layer 3, and two fastening hooks 6 respectively disposed on two sides of the substrate 1 for mounting the whole auxiliary device on a paper pressing device.

The first compensating layer 2 is arranged on one side of the upper surface of the substrate 1 and extends along the length direction of the substrate 1;

a plurality of second compensating layers 3 are arranged on the other side of the upper surface of the substrate 1 opposite to the first compensating layer 2 and are distributed at intervals along the length direction of the substrate 1; the number and the position of the second difference supplementing layers 3 are matched with white edges, close to the cutting opening, of the multiple bundles of cut banknote products which are placed side by side, so that the white edges of the multiple rows of cut banknote products are simultaneously matched and pressurized; in order to prevent the second difference compensating layer 3 from pressing to the pattern/character area of the cut banknote product, the width of the second difference compensating layer 3 should be smaller than the width of the white edges (which are concave structures and are the lowest points on the cut banknote product) of the four edges of the cut banknote product, so as to ensure that the second difference compensating layer 3 falls within the range of the white edges and compact the edges of the product.

When in use, the second difference compensating layer 3 is positioned close to the cutting cut; the position of the first difference compensating layer 2 is far away from the cutting notch, and the contact area of the first difference compensating layer 2 and the cut banknote product is large enough to ensure that the friction force is increased to compress and tension the cut banknote product when cutting.

In order to avoid leaving impressions on the cut banknote product and/or to avoid damaging the cut banknote product (in particular the surface product) when pressed, the connecting side between each second compensating layer 3 and the substrate 1 is provided as an inclined transition zone 4.

The substrate 1, the first compensating layer 2, the second compensating layer 3 and the transition region 4 jointly form a working surface 5 of the whole auxiliary device; the base plate 1 is used for applying pressure to the convex structure on the cut banknote product; the first difference compensating layer 2 is used for compressing and tensioning the cut banknote products during cutting; the second difference compensating layers 3 are used for simultaneously pressing local areas of white edges on multiple stacked cut banknote products which are arranged side by side; the transition zone 4 is used to apply pressure to the transition zone of the raised and lowered formations on the cut banknote products.

The roughness of the working surface 5 is preferably 3.2, depending on the banknote printing ink particles and the friction requirements of the cut paper weight product.

The fastening hook 6 is used to mount the entire auxiliary device under the existing guillotine platen.

To facilitate mass production, the width of the base plate 1 should be smaller than the width of the single cut banknote product to avoid mechanical interference between the paper press and the paper pusher.

The following details the method of use of the present invention with reference to specific examples:

as shown in fig. 3, a single cut banknote product is designed to be open on four sides, which is a single note after offset printing and gravure printing. The bill gray area is the anti-counterfeiting characteristic of paper material, wherein square gray area is the watermark pattern, and the grey area of vertical rectangular is the anti-counterfeiting line, and other geometric figure are characters, number, main scenery pattern etc..

As shown in fig. 4, a light gray area with the width of 5-8mm at the periphery is a printing blank area and is the lowest point part of the note recess; the middle dark gray area is an offset printing pattern area and is a concave secondary low point part of the bill under the action of each intaglio printing pattern and paper material.

As shown in fig. 5, the black strip-shaped area is a security thread and is the highest point part protruding upwards on the bill; the white area is a gravure accumulated ink printing area and is a convex high-point part on the bill; the second gray area (gray scale between light and dark gray areas) is the watermark pattern area and is the raised second highest spot portion of the note.

As shown in fig. 6, the cutting knife edge after the bills are put together shows a situation that the center of the bills is uneven, so that the auxiliary pressing plate matched with the unevenness is needed to perform point-surface matching pressing, and the stable and improved cutting quality can be ensured.

As shown in fig. 7, 5 rows of cut banknote products which are arranged side by side are simultaneously pressed by the invention, each row of banknote products has 100 pieces and 300 pieces, and the number of each row of banknote products is equal; when the bill pressing device is used, the bill pressing device is arranged below a paper pressing device through a hook 6, if the local position of the white edge 7 shown in a figure 7 needs to be pressed tightly by the second difference compensating layer 3 at present, the first difference compensating layer 2 presses the position of a rear area 9 of a bill tightly to press and strain the bill, and the base plate 1 presses the position of a high point protrusion 8 of the bill to realize the point-surface fitting pressing of the bill; when the side edge of the bill needs to be cut, the bill is rotated.
