Equipment for producing microprism reflecting materials through strip-shaped dies

Abstract

The invention discloses equipment for producing microprism reflecting materials through strip-shaped dies. The strip-shaped dies, a heating roller, a heating system, a cooling roller, pressing rollers, a heating plate, a die head, a screw extruder and a peeling roller are included. The equipment is characterized in that the cooling roller is arranged below the heating roller, the peeling roller isarranged on the left side of the cooling roller, the strip-shaped dies are connected in an end-to-end manner to be annularly connected to the heating roller and the cooling roller and move clockwise,continuous microprism arrays are arranged on the outer side surface sides of the strip-shaped dies, and the inner surfaces are attached to the heating roller and the cooling roller; the die head is arranged at the output end of the screw extruder; the heating plate is arranged below the die head and located above the outer surfaces of the strip-shaped dies; and the pressing roller, the heating system and the pressing roller are sequentially arranged on the outer surface positions of the connecting parts of the heating roller and the strip-shaped dies from upper to right.

Description

technical field [0001] The invention belongs to the field of mold production equipment, in particular to equipment for producing microprism reflective materials using belt molds. Background technique [0002] Reflective materials with microprism arrays have reflective properties that other types of reflective materials cannot match, and are widely used in road traffic safety facilities, highway signs, vehicle safety facilities, personal safety protection and other fields. However, there are still considerable problems in existing products produced with advanced technology. For example, the publication number CN106863678A titled equipment and method for making microprism type reflective materials discloses a microprism reflective film formed by UV light curing, mainly The method is as follows: coating a layer of photosensitive resin on the polyester film, molded by a microprism mold, and then cured by a UV lamp, so that the surface of the cured photosensitive resin has a micr...

AI Technical Summary

Problems solved by technology

Using this equipment to produce reflective materials, the hot-melt resin stays on the surface of the heating roller for a relatively short distance, and cannot be naturally attached to the surface of the mold before entering the pressure roller. The hot-melt resin cannot quickly enter the concave-convex gap of the microprism array, resulting in a lower production speed, and It is very likely that tiny air bubbles will be generated in the film, resulting in low reflective brightness and poor appearance
