[0002] Holographic paper is mostly used in anti-counterfeiting, packaging, advertising and other fields. Holographic paper is a special paper that has laser holographic patterns or texts printed on it through special technology during the papermaking process. It has unique optical effects. Different colors and patterns can be seen from different angles. It has high anti-counterfeiting and decorative properties.

[0003] During the production and processing of holographic paper, it will be cut into sizes that meet the use.

[0028] Example

[0029] Reference Figure 1-Figure 4The utility model provides a technical solution: a holographic paper feeding and positioning structure, comprising a rectangular frame 1 and a positioning mechanism 3, and a round roller 2 is installed on the top of the rectangular frame 1, the positioning mechanism 3 comprises a vertical plate 31, the vertical plate 31 is fixedly installed on the top of the rectangular frame 1, a connecting block 311 is slidably installed on one side of the vertical plate 31, a positioning block 32 is fixedly installed on the bottom of the connecting block 311, a cylinder 33 is installed above the rectangular frame 1, a connecting plate 331 is fixedly installed on the telescopic end of the cylinder 33, a rotatable roller 332 is installed on the connecting plate 331, and the roller 332 is rollingly connected to the outer surface of the connecting block 311.

[0030] In a preferred embodiment, the inner side of the rectangular frame 1 is rotatably connected to a conveying roller 4, and the conveying rollers 4 are provided in a plurality and are evenly arranged inside the rectangular frame 1. A cutting table 5 is fixedly installed inside the rectangular frame 1, and a rectangular hole 6 is provided on the upper surface of the cutting table 5. The device conveys the paper to the cutting position, and according to the actual required length, the paper is cut. In order to enable the paper to move horizontally, the conveying rollers 4 are rotatably installed at the inner side of the rectangular frame 1, and the paper moves on the conveying rollers 4, so that the holographic paper can be stably moved to the cutting position.

[0031] In a preferred embodiment, the top of the rectangular frame 1 is fixedly mounted on a vertical plate 7, and a round roller 2 is fixedly mounted on one side of the vertical plate 7. After the holographic paper is produced, it will be collected in rolls, and the paper needs to be unfolded in subsequent processing. Therefore, in order to facilitate the release of the paper, a vertical plate 7 is installed on the top of the rectangular frame 1, and a round roller 2 is fixedly mounted on one side of the vertical plate 7. The paper roller is placed on the round roller 2 and the paper can be rotated by pulling the paper, which is convenient for releasing the paper.

[0032] In a preferred embodiment, a slide groove 8 is provided on one side of the vertical plate 31, and a moving block 9 is arranged inside the slide groove 8. One side of the moving block 9 is fixedly connected to the first spring 17, and one end of the first spring 17 is fixedly connected to the inner wall of the slide groove 8. One side of the moving block 9 is fixedly connected to the round rod 18, and the round rod 18 passes through the interior of the connecting block 311 and is fixedly connected to the interior of the connecting block 311. In order to improve the cutting effect of the paper, the device will squeeze and position the paper while cutting, and can also ensure the normal transportation of the paper when not cutting. Therefore, a slide groove 8 is provided on one side surface of the vertical plate 31, and a movable moving block 9 is arranged inside the slide groove 8, and the moving block 9 is connected to the connecting block 311 through the round rod 18. When the connecting block 311 is squeezed, the positioning block 32 will be driven to squeeze and position the paper, thereby realizing the positioning of the paper.

[0033] When not cutting, the connecting block 311 will be pulled upward together with the positioning block 32 by the first spring 17 so that the paper can be normally transported and used.

[0034] The device can cut the paper while squeezing and positioning it. A cutting mechanism 10 is installed on the top of the rectangular frame 1. The cutting mechanism 10 includes a linkage rod 101, a cutting knife 102 and a second spring 103. A support frame 11 is fixedly installed on the top of the rectangular frame 1. A cylinder 33 is fixedly installed on the top of the support frame 11. The telescopic end of the cylinder 33 is fixedly connected to a connecting seat 12. The connecting seat 12 is movably connected to the linkage rod 101. One end of the linkage rod 101 is fixedly connected to a rectangular bin 13. A limiting rod 14 is fixedly installed inside the rectangular bin 13. A connecting column 15 is movably installed on the limiting rod 14. Two circular plates 16 are installed outside the connecting column 15. A second spring 103 is installed between the two circular plates 16. The bottom of the circular plate 16 at the bottom end of the connecting column 15 is fixedly connected to the cutting knife 102, and one end of the cutting knife 102 is arranged inside the rectangular hole 6.

[0035] In actual use, the telescopic end of the cylinder 33 pushes the connecting rod 101 to rotate, and the rotation of the connecting rod 101 will drive the cutting knife 102 to move, so that the paper can be cut by the cutting knife 102. Since the second spring 103 is installed on the outside of the connecting column 15, when the connecting rod 101 rotates to a vertical state, the circular plate 16 on the connecting column 15 will squeeze the second spring 103, so that the connecting column 15 moves upward, thereby ensuring that the cutting knife 102 can cut the paper normally and avoid damage to the cutting knife 102. As the connecting rod 101 continues to rotate, the cutting knife 102 will be driven to move. When the circular plate 16 is not squeezed by the cutting table 5, the connecting column 15 will be pushed by the second spring 103 and drive the cutting knife 102 to move out a distance so as to completely cut the paper.

[0036] Specifically, the working process or working principle of the holographic paper feeding and positioning structure is as follows: during the production and processing, the holographic paper will be cut into a size that meets the use requirements. The current method of cutting holographic paper is to use a cutting knife 102 to cut the holographic paper after it is unfolded to a certain length. However, the paper is relatively loose at the cutting position. When the cutting knife 102 is used to cut it, it is easy for the cutting end to be rough and uneven, or the cutting knife 102 will push the paper to move, causing the paper to be crowded together, resulting in the inability to cut the holographic paper, which will affect the processing. Therefore, this device is designed to solve this problem.

[0037] The device can stably cut the holographic paper to avoid rough cuts or paper piled up to affect the cutting. The specific operation is to connect an external power supply, place the rolled holographic paper on the round roller 2, then release the holographic paper and move it from the bottom of the first conveying roller 4 to the upper surface of other conveying rollers 4, and continue to convey it on the upper surface of the conveying roller 4. The conveying length of the holographic paper is controlled according to production needs. When the length of the holographic paper is short, it only needs to be pulled on the conveying roller 4. On the contrary, when a longer length is required, the holographic paper can be rolled up by an external winding roller. After reaching the required length, it can be cut.

[0038] When the holographic paper is cut by the device, the telescopic end of the cylinder 33 pushes the linkage rod 101 to rotate, and the rotation of the linkage rod 101 drives the cutting knife 102 to move, so that the paper can be cut by the cutting knife 102. Since the second spring 103 is installed on the outside of the connecting column 15, when the linkage rod 101 rotates to a vertical state, the circular plate 16 on the connecting column 15 will squeeze the second spring 103, so that the connecting column 15 moves upward, so as to ensure that the cutting knife 102 can cut the paper normally, and avoid the cutting knife 102 from being damaged. The connecting rod 101 is controlled to rotate in the opposite direction to drive the cutting knife 102 to move back to the initial position. In this process, the paper can still be cut for use. The cut paper can be directly removed.

[0039] In order to improve the cutting effect of paper, when the telescopic end of the cylinder 33 pushes the connecting rod 101, it will also drive the connecting plate 331 to move, and the movement of the connecting plate 331 will drive the roller 332 to move. As the connecting plate 331 continues to move forward, the roller 332 will move to the top of the connecting block 311, and squeeze the connecting block 311 to press the connecting block 311 downward. When the connecting block 311 moves downward, it will also push the positioning block 32 to move downward and squeeze the paper, and the paper will be stably pressed on the conveying roller 4. The device sets two positioning blocks 32, and controls the two positioning blocks 32 to move downward at the same time, and squeezes and positions the paper on both sides of the cutting table 5, so that the cutting knife 102 can stably cut the paper, make the incision of the paper smooth, and prevent the paper from piling up for subsequent use of the paper.

[0040] The holographic paper in this device is laser holographic paper.

[0041] It should be noted that the cylinder 33 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
