Description

Film swing frame device for horizontally adjusting film of adhesive film

Technical Field

The utility model belongs to the technical field of production of photovoltaic adhesive films, and particularly relates to an adhesive film horizontal adjusting film swing frame device.

Background

Currently, four major types of photovoltaic films include clear EVA films, white EVA films, EPE co-extruded films, and POE films. Among these, EVA film occupies a major market share. The adhesive films are prepared by extrusion casting, and are subjected to the procedures of mixing, melt extrusion, casting embossing, cooling forming, rolling and the like. Production is typically performed using a T-die flat die. However, even minor impurities in the mold cavity flow path can cause thickness deviations in the transverse direction of the emerging film due to the small die lip exit of the mold. These deviations accumulate gradually as the roll is wound, resulting in a phenomenon of rib formation where thick spots rise and thin spots sag.

In current photovoltaic film production, winding rib patterns is a common problem. It not only seriously affects the appearance of the product, but also causes problems such as unevenness, etc., causing breakage of the battery sheet at the time of lamination. There is currently no effective way to deal with the rib streak problem. Once this occurs, the mold or runner can only be shut down for cleaning. Therefore, the device aims to improve the rib phenomenon, reduce the frequency of shutdown cleaning of the die and reduce shutdown loss.
