[0026] Example

[0027] In order to solve the problem that the printing process cost of printing anti-counterfeiting labels in the prior art is high and the anti-counterfeiting patterns produced cannot reflect the sense of luxury, reference Figure 1 and Figure 2 As shown, the present application discloses a photolithography printing process for anti-counterfeiting labels, including a carrier 10, a cardboard unwinding machine 20 connected to the carrier in sequence, an embossing press 30, a photolithography printer 40, a cutting machine 50 and a feeding belt conveyor 60. The specific process flow includes the following steps:

[0028] In the first step, the cardboard unwinder unwinds the cardboard to the embossing press for embossing molding;

[0029] In the second step, the photolithography printing machine absorbs the cardboard with the embossed relief and moves its photolithography printing head longitudinally and transversely on the cardboard to perform photolithography printing;

[0030] In the third step, the cutting machine cuts the cardboard formed with embossed relief and completed with photolithography printing;

[0031] In the fourth step, the cut printed products are moved to the unloading belt conveyor for unloading.

[0032] Based on the above process, the anti-counterfeiting label printed by the present application has a three-dimensional effect, and compared with the traditional printing method, the pattern will not fall off easily through photolithography printing, and has strong practicality.

[0033] The cardboard unwinding machine of the present application includes a frame 21 arranged on one side of the machine, a feeding motor 22 arranged on the frame, an air inflation shaft 23 connected to the output shaft of the feeding motor, and a cardboard roll 24 mounted on the air inflation shaft. In the specific implementation process, the feeding motor controls the cylinder shaft to rotate in real time, so that the cardboard roll can release paper successively. In addition, the present application sets a guide roller 70 above the carrier between the embossed relief and the cardboard unwinding machine, so that the cardboard released from the cardboard roll can be guided.

[0034] The embossing press of the present application specifically includes an inverted L-shaped plate 31 arranged on a carrier at the rear side of a cardboard unwinding mechanism, a first hydraulic cylinder 32 arranged above the transverse portion of the inverted L-shaped plate, an upper embossing plate 33 arranged below the transverse portion of the inverted L-shaped plate and connected to the first hydraulic cylinder, a profiling groove 331 provided at the bottom of the upper embossing plate, a lower embossing plate 34 arranged on the carrier below the inverted L-shaped plate, and a profiling protrusion 341 provided on the lower embossing plate, an installation groove 12 is provided on the corresponding carrier below the transverse portion of the inverted L-shaped plate, and the lower embossing plate is installed in the installation groove, and when the paper roll is released to a set length and is above the lower embossing plate, the first hydraulic cylinder drives the lower embossing plate to descend, and with the cooperation of the profiling protrusion and the profiling groove, a three-dimensional pattern will be printed on the cardboard.

[0035] The photolithography printing machine of the present application includes two longitudinal gantries 41 arranged side by side on a carrier at the rear side of an embossing press, two longitudinal servo screw modules 42 respectively arranged under the cross beams of the longitudinal gantries, a transverse servo screw module 43 connected to the two longitudinal servo screw modules, and a photolithography printing head 44 connected to the bottom of the servo screw module. When printing on a cardboard with a three-dimensional pattern, the two longitudinal servo screw modules cooperate with the transverse servo screw module to drive the photolithography printing head to move longitudinally and transversely, thereby realizing photolithography printing on the cardboard.

[0036] In one of the specific embodiments, the present application provides a linear groove 11 on the rear side of the carrier on the embossing press, and a vacuum adsorption belt conveyor 70 is provided between two longitudinal brackets of the linear groove. The unloading belt conveyor is provided in the linear groove on the rear side of the vacuum adsorption belt. When the cardboard of a set length enters the vacuum adsorption belt conveyor, the vacuum adsorption belt conveyor will adsorb the cardboard of the set length. After the pattern is printed on the cardboard of the set length, the vacuum adsorption belt conveyor will stop adsorbing the cardboard with the printed pattern and transport the cardboard forward until the next section of the cardboard of a set length arrives on the vacuum adsorption belt conveyor, and the vacuum adsorption belt conveyor will again adsorb the section of cardboard without the printed pattern.

[0037] The cutting machine of the present application includes a transverse plate 51 arranged at the rear side of the photolithography printing mechanism, a second hydraulic cylinder 52 arranged above the transverse plate, a cutting knife 53 connected to the second hydraulic cylinder below the transverse part of the second inverted L-shaped plate, and a cutting pad 54 arranged in a linear groove between the vacuum adsorption belt conveyor and the unloading belt conveyor and corresponding to the cutting knife. When a cardboard of a set length with a printed pattern reaches the unloading belt conveyor and the vacuum adsorption belt conveyor adsorbs the cardboard above it, the second hydraulic cylinder drives the cutting knife to descend and cooperate with the cutting pad, so that the printed cardboard can be cut, and the cut printed cardboard will flow away through the unloading belt conveyor.
