Grape preservative slow release packing precise release hole manufacturing device and application method

The invention discloses a grape preservative slow release packing precise release hole manufacturing device. The device comprises a machine frame, a winding and unwinding mechanical transmission mechanism, a pulse laser generator, a laser pipe cooling system, and a smoke and paper chip sucking device. The winding and unwinding mechanical transmission mechanism is mounted on the machine frame; the pulse laser generator is vertically mounted on the machine frame, and is perpendicular to a frame platform surface; the laser pipe cooling system is a closed cooling water circulating system for cooling a laser pipe to guarantee normal operation; and the smoke and paper chip sucking system adopts a vacuum pump and a pipe to suck away smoke and paper chips generated by laser hole manufacturing to keep cleanness of the environment and a hole manufacturing working surface. The precise release hole manufacturing device reduces the manual hole drilling procedure before use of preservative by precise positioning and precis
