ABSTRACT:
An electric dispenser for wrap film includes a base, two side covers, a conveying track, a driving device, a cutting device, an accommodating case and a bottom cover. The conveying track is contained in the base, driven by the driving device to pull out the wrap film. The cutting device includes a driving motor, a threaded bar, a blade fixing base and an auxiliary rod. The driving motor is commanded by the driving device to drive the threaded bar to rotate to enable the blade fixing base to move along the threaded bar. The blade-fixing base has a blade extended to the surface of the conveying track to cut off the wrap film. The accommodating case is set on the top of the base, for positioning the wrap film in it. The wrap film is replaceable.
