Description

Technical Field

[0001] The utility model relates to the technical field of film production, in particular to production equipment for a step-structured light-guiding PC film. Background Art

[0002] At present, most of the light-guiding PC films on the market are produced by cast-film machines. For some films with smooth surfaces, smooth and flat cooling cast-film rollers are used, and for printed films, printed cooling cast-film rollers are used. Regardless of whether the smooth film or the printed film is made, the overall thickness remains consistent.

[0003] For example, Chinese patent CN216831876U discloses a casting machine, which includes a conveying mechanism, a hopper, a heating mechanism, an extrusion barrel, a die head and a casting roller. The raw material in the hopper is sent to the heating mechanism for plasticization through the conveying mechanism, and then the plasticized plastic liquid is squeezed onto the die head through the extrusion mechanism. The plastic liquid in the die head flows to the casting roller, and the plastic liquid is cooled and cast by the casting roller.

[0004] However, there is a film with a step structure on the market. Its current production situation is mostly to initially form it through casting and then obtain the required step structure through etching; after many adjustments, it was found that the existing casting machine, when producing a film with a thickness greater than 0.5 mm, the step height increased from 0.05 mm to 0.2 mm, and a casting roller corresponding to the step film structure was used. The appearance of the finished product's boss shape is complete and the size can basically meet the requirements; when producing a film with a thickness less than 0.5 mm, it is difficult to directly perform casting while ensuring that the stage is full. The stage of the film after production is prone to depression and unevenness due to insufficient raw materials.

[0005] Based on this, the utility model designs a production device for a step-structure light-guiding PC film to solve the above problems. Utility Model Content
