A flat belt compound process and equipment

Abstract

The invention belongs to the field of material composition, and particularly relates to a flat belt type compounding process. According to the process, firstly, high-temperature heating is performed through a strip-shaped heating plate; the temperature is uniformly conducted onto a Teflon flat belt; further, the composite materials on the Teflon flat belt and glue attached onto the composite materials are preheated and prepressed; then, the composite materials are pressed again through a pair of press rollers; then, the composite materials are cooled and shaped by the strip-shaped cooling plate; finally, materials are conveyed out through the Teflon flat belt; the total compounding of the materials is completed. The invention also provides equipment used for realizing the process. According to different composite materials, through controlling the temperature, the speed and the pressure, the materials are perfectly attached and have high intensity; the upper and lower Teflon flat belts achieve uniform gaps and precise gap regulation; the flatness and no drape of the surface composite materials are ensured.

Description

technical field [0001] The invention belongs to the field of material compounding, and in particular relates to a flat-belt compounding process and equipment. Background technique [0002] At present, in industrial textiles, automotive interior plutonium, filter materials, special clothing, aviation materials, medical protection and other industries, non-woven products, honeycomb panels, sponges, hot-melt films, glue nets and other materials with two or more layers When compounding, the process of gluing, pressing, drying, cooling and shaping is usually carried out on the roller compound machine with glue. For special compounding such as non-adhesive compounding of materials and coils, multi-layer soft material compounding boards, etc., the process used on the roller compounding machine is not suitable. It is also very troublesome to process some sheet materials, small batches, and materials with high requirements for upper and lower layer compounding. Not only is the machi...

Problems solved by technology

[0002] At present, in industrial textiles, automotive interior plutonium, filter materials, special clothing, aviation materials, medical protection and other industries, non-woven products, honeycomb panels, sponges, hot-melt films, glue nets and other materials with two or more layers When compounding, the process of gluing, pressing, drying, cooling and shaping is usually carried out on the roller compound machine with glue. Special compounding such as non-adhesive compounding of materials and coils, multi-layer soft material compounding boards, etc., the process used on the roller compounding machine is not applicable

It is also very troublesome to process some sheet materials, small batches, and materials with high requirements for upper and lower layer compounding. Not only is the machine bulky, the heat loss is large, and the fastness of the upper and lower compound layers of the material is not the same, which greatly affects the compound quality.
