Automatic waterproof film winding device with winding core

The invention relates to an automatic waterproof film winding device with a roll core, which comprises a rack, and a winding mechanism, an adhesive tape pasting mechanism, a cutting mechanism, a feeding mechanism and a discharging mechanism which are arranged on the rack, the feeding mechanism rotationally moves to forward convey a waterproof film, the roll core is arranged on an air expansion shaft of the winding mechanism, and the adhesive tape pasting mechanism is arranged on the discharging mechanism. The adhesive tape pasting mechanism connects the roll core and the waterproof film together through an adhesive tape, the inflatable shaft drives the roll core to rotate for rolling, after the preset thickness is achieved, the adhesive tape pasting mechanism moves upwards and presses tightly, the adhesive tape is pasted to the outer ring of the roll material, and the cutting mechanism presses the waterproof film tightly and cuts off the waterproof film. And after the residual waterproof film is rolled, the a
