[0009] The circumferences of the second plate axis area (3) and the third plate axis area (5) are consistent with the circumference of the first plate axis area, and straight lines for aligning the initial mark are respectively provided on their surfaces;

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

Figure 1 As shown, the multifunctional plate shaft according to the present invention is used for laser holographic anti-counterfeiting packaging printing, and includes a first plate shaft area 1, a first groove 2, a second plate shaft area 3, a second groove 4 and a third plate shaft area 5 along the axial direction, which will be explained in more detail one by one below.

[0025] As for the above-mentioned plate shaft, it is a special-shaped plate shaft as a whole, and can realize the line positioning and embossing of special edition laser holographic anti-counterfeiting patterns, while effectively overcoming various technical problems existing in similar products in the existing technology.

[0026] The circumference of the first plate axis area 1 is provided with an initial mark for registration detection, and the first plate axis area 1 is used to invade the ink tank and perform scraper printing when in operation.

[0027] More specifically, according to a preferred embodiment of the present invention, the length of the first plate axis area 1 along the axial direction is preferably designed to be 20 mm to 30 mm. Its surface can be engraved with a mark and pattern for registration detection and identification. According to the position of the engraved registration mark, a straight line is engraved on the second plate axis area 3, the second groove 4, and the third plate axis area 5 respectively. The position of the straight line is aligned with the registration mark position, which serves as the starting line for plate mounting and keeps the plate seam aligned with the registration mark.

[0028] The first groove 2 has a first depth that is recessed inward relative to the first plate axis area 1, and is used to isolate the second plate axis area 3, the second groove 4, and the third plate axis area 5 (3) from invading the material groove, even though the first plate axis area 1 can independently invade the material groove. More specifically, according to another preferred embodiment of the present invention, the depth of the first groove 2 is preferably designed to be 10 mm to 40 mm, and its width is preferably 2 mm to 20 mm.

[0029] The circumferences of the second and third axis regions 3 and 5 are consistent with the circumference of the first axis region, and straight lines for aligning the initial mark are respectively provided on their outer sides.

[0030] In addition, the second groove 4 has a second depth of the inward groove relative to the first plate axis area 1, which is used to paste the laser holographic plate and make the plate circumference of the laser holographic plate after pasting consistent with the plate circumference of the first plate axis area, and the outer side of the second groove 4 is also provided with a straight line for aligning the initial mark.

[0031] More specifically, according to another preferred embodiment of the present invention, the depth of the second groove 4 is preferably designed to be 0.5mm to 2mm, and its width is preferably 350mm to 1000mm. During operation, the second groove is used to attach the laser holographic plate (including nickel plates and plastic plates) and control the plate perimeter and the starting position of the plate after attachment, ensuring the positional accuracy of the special plate pattern on the laser holographic plate after attachment, and ensuring that the plate perimeter after attachment is equally or extremely close to the first plate axis area, the second plate axis area, and the third plate axis area.

[0032] In summary, according to the multifunctional plate shaft of the present invention, through the comprehensive design of its internal components and their settings, a holographic special-shaped plate shaft can be obtained in a compact and easy-to-operate manner to effectively overcome various defects of existing equipment. Moreover, the plate shaft can effectively avoid secondary positioning fluctuations and the like during the process of molding holographic special plate patterns, while realizing the organic combination of holographic special plate patterns and color printing processes. It can adapt to various complex working environments, while improving the convenience of subsequent maintenance and is less likely to produce quality risks. Therefore, it is suitable for specific occasions of laser holographic anti-counterfeiting packaging printing such as holographic anti-counterfeiting paper, especially holographic anti-counterfeiting positioning paper.
