Description

Technical Field

[0001] The utility model belongs to the technical field of polyvinylidene fluoride plate production, in particular to a cutting device for polyvinylidene fluoride plate production. Background Art

[0002] Polyvinylidene fluoride, abbreviated as PVDF, is a highly non-reactive thermoplastic fluorine-containing polymer with excellent properties such as anti-aging, chemical resistance, weather resistance, and ultraviolet radiation resistance, and can be used as engineering plastics.

[0003] Existing polyvinylidene fluoride plates need to be cut using cutting equipment after production. Existing cutting equipment usually directly presses the cutting knife down for cutting. This method will cause warping or deviation during cutting, which not only affects the cutting size, but also makes the cutting surface uneven, affecting the appearance. Therefore, we propose a cutting equipment for the production of polyvinylidene fluoride plates. Utility Model Content

[0004] The purpose of the utility model is to provide a cutting device for the production of polyvinylidene fluoride plates.
