The invention provides a melt differential electrospinning device and method for continuous direct plasticizing feeding of films. The device mainly comprises side plates, an unwinding roller, a motor, a heating roller, a scraper, a baffle plate, a blanking ring, an electrode plate, a high-voltage electrostatic generator, an air compressor and a collecting roller. A film is wound on the unwinding roller, and both ends of the heating roller are electrified and heated to a set temperature to ensure rapid melting of the film. The film is drawn to the surface of the heating roller with an insulating tool and gradually tightened. The motor is adjusted to set appropriate rotating speeds for the heating roller and the unwinding roller to achieve an optimal feeding speed. By directly using a film rapidly extruded from an extruder as the raw material, the invention solves the problem of melt degradation and oxidation and significantly improves spinning quality. In addition, the melt flows out through a narrow gap for spinning, producing multiple jets and high spinning efficiency. The device has a simple structure, improves both production efficiency and product quality, and meets the stability requirements of industrial production.
