Flame-retardant ceramic fiber non-woven fabric cutting device

The utility model relates to non-woven fabric processing equipment, in particular to a flame-retardant ceramic fiber non-woven fabric cutting device. The non-woven fabric cutting device comprises a base, and a working assembly is installed at the top of the base and used for containing a non-woven fabric semi-finished product to be cut; supporting assemblies are slidably connected to the tops of the two sides of the working assembly, and the included angle formed by the connecting line between the two supporting assemblies and the base can be changed; a distance adjusting assembly is connected between the two supporting assemblies in a sliding mode, and when an included angle formed by a connecting line between the two supporting assemblies and the base is changed, one supporting assembly is fixed; according to the flame-retardant ceramic fiber non-woven fabric cutting device, the arranged supporting assembly slides on the sliding rail, meanwhile, the angle adjuster rotates at the top of the sliding block, th
