An elastic paper feed belt

Abstract

The invention discloses an elastic paper feeding belt which comprises a framework layer, sheet layers, buffer layers, adhesive layers and friction layers. The framework layer is a meddle layer, the sheet layers, the buffer layers, the adhesive layers and the friction layers are outwardly and sequentially arranged on two sides of the framework layer, the framework layer comprises polyester or aramid fabrics which are subjected to activating treatment, the sheet layers are made of TPU (thermoplastic polyurethane), TPEE (thermoplastic polyester elastomer) or TPA (terephthalic acid) materials, connecting ends of the paper feeding belt are of toothed structures, and teeth are adhered with one another by the sheet layers to form an annular structure. The buffer layers are made of rubber, the adhesive layers are made of high-polymer adhesive, the friction layers are made of rubber, and the outer surfaces of the friction layers are smooth surfaces of patterned surfaces. The elastic paper feeding belt has the advantages that the elastic paper feeding belt is insensitive to environmental conditions, is good in bending effect, elasticity and paper feeding effect, high in connector strength, free of requirements on running directions and stable in friction coefficient, and is abrasion-resistant and bending-resistant, the service life of the elastic paper feeding belt can be prolonged, and the like.

Description

technical field

[0001] The invention relates to a paper feeding belt, which belongs to the technical field of printing and packaging machinery. Background technique

[0002] In recent years, the domestic printing and packaging industry has developed various types of high-end printing and packaging machinery, such as offset printing machines, folder gluers, bookbinding machines, paper folding machines and other advanced equipment. The paper feeding belt is its key component, which requires good elasticity, high friction coefficient, Wear-resistant and other characteristics, in the work, multiple belts convey the paper or carton on the conveying surface in groups, and complete the packaging molding at the same time. However, in the prior art, the nylon sheet-based paper feeding belt used in the prior art has the phenomenon of lotus leaves appearing on the edge due to the difference in ambient temperature and humidity. Due to the increase of conveying speed and the reduction o...
