A kind of manufacturing method of embossing plate roller

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 ...

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
