Problems solved by technology

At present, most of the rotating needle-free electrospinning devices are metal shafts. It is a common method to charge the electrospinning emitter by directly applying power to the metal shaft through a brush. However, the metal shaft is also charged Distribution, the generated electric field affects the electric field of the spinning emitter, and then affects the spinning effect, and at the same time, it will also cause energy waste

Abstract

The invention relates to a nonmetal rotating shaft convenient to power, and belongs to the field of nanometer fiber preparation. The rotating shaft comprises a supporting sleeve, two supporting sleeve end covers, a center shaft, a clamping spring, a bearing, a fixing ring and a bearing pedestal. The supporting sleeve is sleeved with an electrostatic spinning emitting electrode. The supporting sleeve and the two supporting sleeve end covers form a whole. One end of a wire is connected with the electrostatic spinning emitting electrode, and the other end of the wire penetrates into the center shaft from a small hole in the supporting sleeve, is led out from the small hole close to the end face of the center shaft and is tied to the clamping spring. The other metal wire is tied to the fixing ring, and the other end penetrates out from a small hole of the bearing pedestal, then, the fixing ring is installed on the matching face of a bearing and the bearing pedestal. In this way, an electrode of a direct current voltage power source is clamped to the wire penetrating out from the bearing pedestal, and voltage can be conveniently transmitted to the electrostatic spinning emitting electrode. Influences and energy waste on an electric field can be effectively lowered, and the problem that wires are wound is effectively avoided.

Description

technical field [0001] The invention relates to a non-metallic rotating shaft convenient for electrification, in particular to a non-metallic rotating shaft used for a rotary needleless electrospinning emitter, and belongs to the field of nanofiber preparation. Background technique [0002] In a narrow sense, nanofibers refer to fibers with a diameter of less than 100nm. They have the characteristics of large specific surface area and high porosity, and are widely used in high-efficiency filtration materials, wound dressings, tissue engineering, composite materials, battery electrodes, and micro-nano devices. [0003] Electrospinning is a method of preparing nanofibers by stretching a polymer solution or melt by an electric field force generated by a high-voltage DC power supply, and is one of the most effective techniques for preparing nanofibers. At present, there are two main types of electrospinning technologies used for mass production of nanofibers, namely, multi-needl...
