Abstract

The invention discloses a millstone type melt differential electrostatic spinning device, which mainly consists of a driving motor, a motor supporting frame, a speed reducer, an end cover, a machine barrel, a fixing bolt, a moving millstone, a nozzle, a driving shaft, a self-locking nut, a gasket, a heating device, a temperature sensor, a bearing, a feed cylinder and an air flow duct. The device utilizes a millstone extruder for feeding. The flow is precisely controlled and the melt process is shortened. The decomposition of the polymer melt due to the long process is effectively prevented. The device has the advantages of simple structure, small volume, small occupied space, no special requirement on the feeding mode and suitability of small size granule granules and powder. Large particulate material has advantages due to the existence of the millstone. The side of the moving millstone is provided with a spiral gradual flow passage, gradually becoming shallow from top to bottom and providing additional conveying force to the melt and also uniformly distributing the melt on the outer diameter of the moving millstone. The clearance between the moving millstone and the machine barrel of the end cover is adjustable. The process requirements of processing more kinds of materials can be met.

Description

technical field [0001] The invention relates to a disc type melt differential electrostatic spinning device, which belongs to the field of electrostatic spinning. Background technique [0002] With the continuous development of nanotechnology, nanofibers are more and more widely used in daily life, and electrospinning is recognized as the simplest and most effective method for preparing nanofibers. Due to its high porosity and low osmotic resistance, electrospun nanofibers have a wide range of applications and development prospects in micro-nanofiltration, cell culture, oil-water separation, and clothing. [0003] At present, the feeding methods of electrospinning include pressure feeding, screw extruder feeding, etc., but each feeding method has certain shortcomings. Pressure feeding is difficult to control the feeding rate, which is not conducive to producing continuous and uniform fiber. Although the screw feeding can control the feeding rate, the long melt channel is n...
