Problems solved by technology

There is a problem with this production method, such as figure 1 and figure 2 As shown, the cross-section of the embossed plate 20 cut in a flat state is rectangular, and its upper and lower surfaces have the same length. , The lower two surfaces form concentric circles, and because the molded plate 20 itself has a certain thickness, when the upper and lower surfaces of the molded plate 20 have the same length, an angle is formed between the end face of the first connecting end and the end face of the second connecting end, specifically It shows that the lower surface is a complete circle at the junction of the roller surface, but the upper surface forms a plate gap due to the lack of length d, and the gap width can often reach more than 0.3mm, which is greater than the 0.2mm width that can be recognized by the human eye, resulting in There are obvious seams visible to the naked eye on the produced holographic film, which affects the product quality of the holographic film

Embodiment 1

[0050] This embodiment provides a method for making a molded embossing roller, please refer to image 3 , the steps are as follows:

[0051] (1) Fix the first connecting end 210 and the main body portion 220 of the manufactured embossed plate 20 to the roller 10 .

[0052] see Figure 4 Firstly, the first end 211 of the first connecting end 210 is set in the same plane as the central axis of the roller 10, after the position of the first connecting end 210 is determined, it is fixed on the roller 10, and the embossed plate 20 is wound around the roller The peripheral surface of the cylinder 10 is attached so that the main body portion 220 of the embossed plate 20 is closely attached to the peripheral surface of the cylinder 10 .

[0053] (2) Cutting the second connecting end 230 of the embossed plate 20 , wherein the length of the inner side of the embossed plate 20 in the circumferential direction of the roller 10 is equal to the length of the circumferential diameter of th...

Embodiment 2

[0059] This embodiment provides a method for making a molded embossing roller, please refer to image 3 , the steps are as follows:

[0060] (1) Cut the first connecting end 210 of the embossed plate 20 .

[0061] Cut the first connecting end 210 of the embossed plate 20 according to the bleed line in a flat state according to the design graphic of the embossed plate, remove excess bleeding edge material, and make the first end 211 of the first connected end 210 a plane , and the first end portion 211 is perpendicular to the upper and lower surfaces of the embossed plate 20 .

[0062] (2) Fix the first connection end 210 and the main part 220 of the embossed plate 20 to the roller 10 , wherein the length of the inner side of the embossed plate 20 in the circumferential direction of the roller 10 is equal to the circumferential length of the roller 10 .

[0063] see Figure 4 Firstly, the first end 211 of the first connecting end 210 is set in the same plane as the central a...

Embodiment 3

[0070] This embodiment provides a method for making a molded embossing roller, please refer to image 3 , the steps are as follows:

[0071] (1) An adhesive material is provided on the inner surface of the embossed plate 20 .

[0072] see Figure 5 , the double-sided adhesive material 30 with the release layer 40 is directly attached to the inner surface of the embossed plate 20 , so that the inner surface of the embossed plate 20 is viscous, so that it can be attached to the roller 10 .

[0073] (2) Cut the first connecting end 210 of the embossed plate 20 .

[0074] Cut the first connecting end 210 of the embossed plate 20 according to the bleed line in a flat state according to the design graphic of the embossed plate, remove excess bleeding edge material, and make the first end 211 of the first connected end 210 a plane , and the first end portion 211 is perpendicular to the upper and lower surfaces of the embossed plate 20 .

[0075] (3) Fix the first connection end 2...

Abstract

The invention relates to a manufacturing method of a molding plate roller. The embossed plate roller includes the following steps: fixing the first connecting end and the main part of the embossed plate to the roller; cutting the second connected end of the embossed plate, wherein the inner side of the embossed plate is on the roller The length in the circumferential direction is equal to the length of the circumference of the roller; the second connecting end is fixed to the roller. In the above production method, the first connecting end and the main part of the molded plate are first fixed on the roller, and then the second connecting end of the molded plate is cut, because the molded plate is on a curved surface during the process of cutting the second connecting end of the molded plate Therefore, the length of the upper and lower surfaces of the molded plate can be cut according to the actual length requirements, so that the error of the plate seam can be controlled within 0.2mm. Since the width of the plate seam is smaller than the minimum width visible to the naked eye, it is not visually correct. It can be seen that the product quality of the holographic film is further improved.

Description

technical field [0001] The invention relates to the field of laser holographic image-text embossing equipment, in particular to a manufacturing method of an embossing plate roller. Background technique [0002] Before preparing the holographic film, it is necessary to stick the prepared laser holographic molded plate on the roller. The preparation method in the prior art is: first, cut the molded plate in a flat state according to the circumference of the roller, and then press the molded plate The plates are fixed on the circumference of the rollers. There is a problem with this production method, such as figure 1 and figure 2 As shown, the cross-section of the embossed plate 20 cut in a flat state is rectangular, and its upper and lower surfaces have the same length. , The lower two surfaces form concentric circles, and because the molded plate 20 itself has a certain thickness, when the upper and lower surfaces of the molded plate 20 have the same length, an angle is ...
