Description

Technical Field

[0001] The utility model relates to a shearing device, in particular to a shearing device used for the production of highly wear-resistant impregnated paper, and belongs to the technical field of impregnated paper processing. Background Art

[0002] Highly wear-resistant impregnated paper is made through processes such as impregnation, drying, coating and curing. It has excellent wear resistance and strength and is widely used in decorative panels and flooring. In the production of highly wear-resistant impregnated paper, precise cutting by shearing devices is required to ensure that the paper size and edges are neat and to improve production efficiency and product quality.

[0003] During the high-frequency and high-intensity cutting process, the tool rubs against the material, causing the cutting edge to gradually wear out and eventually become blunt. Tool wear will lead to reduced cutting quality, uneven cutting edges, increased burrs, and affect product appearance and precision. Therefore, the tool needs to be replaced and maintained regularly, increasing operating costs and downtime. For this reason, we provide a shearing device for the production of highly wear-resistant impregnated paper. Utility Model Content
