Stone paper film forming device and technology

Abstract

The invention relates to a stone paper film forming device and a technology. The device consists of an extruder and a film blowing device, wherein the extruder and the film blowing device are horizontally arranged in a straight shape, do not have high requirements on plants, are not limited by fields, are safe, have simple technology and low cost, and are produced in a dry method without pollution; the extruder is provided with a feed press-in heating segment, a foamed assistant infusion interface and cooling temperature control mixing segment, and a heating melt extrusion segment; the film blowing device comprises a compressor, a compressed air charge interface, an air blower, an air-cooled air ring, a V-shaped gradually flattened and planished transition frame, and a traction stretch flattening roll. The extrusion and film blowing technology is characterized in that inorganic stone powder and other materials are modified and mediated into ball-shaped materials, fed, pressed into the extruder and heated, a foaming agent and a nucleating agent are infused according to the need, the materials are gradually heated to be melted so as to extrude an O-shaped tip, the compressed air is charged into a paper film tube for film blowing, and a paper film base material is formed via traction stretch, external air cooling, shaping and rolling; and then a stone paper product is formed via edge cutting, corona, coating, drying and finishing.

Description

Technical field: [0001] The invention belongs to the field of light industry, and relates to stone paper-making production equipment, in particular to equipment and technology for manufacturing new stone paper. Background technique; [0002] The existing Taiwan Longmeng Environmental Protection Paper Group Co., Ltd. uses natural inorganic mineral powder, polyethylene, additives, etc., to make granular materials through mixing and kneading, and controls the temperature of the extruder to soften the granular materials. The molten material is discharged from the ○-shaped die to form a film tube, which is inflated with compressed air inside the film tube, blown and cooled outside the film tube, and at the same time stretched and pulled to make the film tube reach the inner extension and outer extension of the film tube. Wheel traction, bilateral trimming, corona winding, compounding, coating and drying to make environmentally friendly paper with bidirectional tissue strength. ...
