UV (Ultraviolet) curing optical film production device

Abstract

The invention relates to a UV (Ultraviolet) curing optical film production device. The UV curing optical film production device comprises a coating device, a transmission device, a heating film-pressing device, a cooling roller and a rolling device, and further comprises a material-containing device and a uv photo-curing device, wherein the material-containing device is used for pouring out photosensitive resin; the photosensitive resin is uniformly and flatly paved in an annular micro-prism mould on the outer surface of a conveyor belt through the transmission device; the UV photo-curing device is used for the photocuring of the photosensitive resin; the UV photo-cured photosensitive resin and a resin film coated with the photosensitive resin enter the heating film-pressing device for being heated and pressed; the UV photo-curing device is further arranged on the heating film-pressing device for carrying out UV photocuring on the film-pressed photosensitive resin again; the photo-cured photosensitive resin and the micro-prism structure formed on the photo-cured photosensitive rein form a laminated film. According to the UV curing optical film production device, the micro-prism structure is formed by uv photocuring of the photosensitive resin by adopting double-coating photosensitive resin and a double-UV photocuring way, so that the hardness, the scratch resistance, the heat resistance and the solvent resistance of the UV curing optical film production device are greatly improved.

Description

technical field [0001] The invention relates to a production equipment of a reflective film, in particular to a production equipment of a UV curing type optical sheet. Background technique [0002] At present, in the production and processing process of the existing micro-prism reflective film, limited by the production process and equipment manufacturing capacity, it usually relies on intermittent production technology to produce the micro-prism reflective film into a product form with limited specifications. The maximum area of ​​a single sheet is only It can reach 48 cm × 48 cm. If the length of the required reflective film product is relatively large, it is necessary to splicing several micro-prism reflective films into a reflective film product of the required length through splicing technology. However, in the actual production and processing process, the production efficiency of this kind of single-piece production and splicing processing is low, and it will lead to a...

AI Technical Summary

Problems solved by technology

The mold obtained by the grinding method is small and thick, and the size of the microprism is large, which is only suitable for injection molding and replication, and the reflective material produced can only be used for vehicle passive safety protection devices and road contour signs and other fields
