Description

Technical Field

[0001] The utility model relates to the technical field of optical film material slicing, in particular to an optical film material slicing device. Background Art

[0002] Optical film is a medium material that is coated with one or more polymer adhesive layers or metal layers on an optical substrate or optical element, thereby changing the propagation characteristics of light on the surface of the medium, and further realizing optical functions such as light transmission, light conversion, light modulation, and spectrum and energy segmentation and synthesis. However, the width of the optical film after production is relatively wide, and the large roll of optical film needs to be sliced ​​to meet different application requirements.

[0003] The blades of existing optical film slicing equipment are usually fixed on a roller. This means that when a blade is damaged and needs to be replaced, the roller must be removed and the corresponding blade must be removed for replacement, which is rather troublesome. In addition, since the blade is fixed on the roller, the blade cannot be adjusted as needed to slice optical films of different sizes. Therefore, we propose an optical film slicing equipment to solve the above problems. Utility Model Content
