A corner cutting device for a bag making machine

Abstract

The utility model relates to packing bag production technical field, concretely is a kind of corner cutting device for packing bag making, including rack, the support platform is fixed on the rack, two blocks of backboard are symmetrically equipped on the support platform, the cutting assembly for being used to the corner cutting of packing bag down pressure is fixed on the top of the rack, the pressure applying assembly for following the cutting assembly down pressure is fixed on the cutting assembly and provides the compression force of compacting;By setting pressure applying assembly, compacting component, clutch component and adjusting component, in the corner cutting process, by the meshing and disengaging of movable gear plate and fixed gear plate, sleeve dynamic unlocking is ensured, the compression of pressure spring does not occur greater change, keep stable compression force, avoid the problem that packing bag shifts or is damaged due to unstable compression force, the precompression of pressure spring can be adjusted simultaneously by rotating screw rod, and then according to the characteristics such as the material, thickness of different packing bag, flexible adjustment compression force, the versatility of device is improved.
