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...
