Problems solved by technology

[0005] In the production process of the holographic molded film 7', the tension roller 4 of the molding device has a tension and flattening effect on the film material 7, and the tension roller 6 has a tension and flattening effect on the holographic molded film 7', but, due to production During the process, factors such as temperature, film material 7 or holographic molded film 7' characteristics, stop and restart etc. are constantly changing, especially changes in film material 7 or holographic molded film 7' characteristics (such as thickness, expansion rate) will affect the holographic molded pressure. The format of the film 7' has a great influence, resulting in irregular changes in the format of the holographic molded film 7', and even a sudden change, with an error of more than 0.5-2mm
[0006] Therefore, the existing molding device cannot produce a holographic molded film with high width accuracy.
This kind of holographic molded film with low precision will further expand the error after processing such as slitting, compounding, and peeling.

Abstract

The invention discloses a method for manufacturing a pressed film of an equal-plate-breadth holographic mask and a mold pressing device thereof. The method comprises the following steps: detecting the actual plate breadth of the pressed film of the equal-plate-breadth holographic mask in a constant-tension control section, comparing the detected actual plate breadth with the preset plate breadth to obtain a plate breadth difference, adjusting the tension of a variable-tension control section according to the plate breadth difference, facilitating film material of the variable-tension control section to stretch or shrink after entering the constant-tension control section in order to compensate the plate breadth difference and to produce the high-precision pressed film of the equal-plate-breadth holographic mask. The mold pressing device comprises a set of leading-in traction rollers, a set of mold pressing rollers, a set of leading-out traction rollers, a guide roller and a stretch roller, which are arranged in order. The mold pressing device is characterized in that: the mold pressing device is provided with a tension control device which is adjusted to compensate the plate breadth difference caused by changes of temperature and properties of the film material, so as to control the difference within a certain range, thereby improving the precision of the plate breadth and outputting high-precision pressed films of the equal-plate-breadth holographic mask.
