Description

technical field [0001] The invention belongs to the field of textile machinery, in particular to a high-voltage electrostatic spinning machine with adjustable spinning angle. Background technique [0002] High-voltage electrospinning is a special fiber manufacturing technology. The polymer solution is jet-spun under the action of a strong electric field, and finally a polymer filament with a nanometer diameter can be obtained because of its simple manufacturing device and low spinning cost. And the advantages of many kinds of spinning are widely used in the preparation of nanofiber materials. Spinning angle is an important factor affecting spinning effect. Improper launching device angle will cause solution dripping, gravity interference with electric field and other phenomena, which will reduce spinning quality. For solutions with different ratios, the best spraying angle is also Different, so it is necessary to continuously adjust the angle of the launch device to get the...

AI Technical Summary

Problems solved by technology

First of all, the size of the receiving roller and the receiving plate is fixed, and the receiving and spinning capacity is limited, so it cannot be adjusted for different spinning volumes

Secondly, when the receiving plate is used as the receiving device, the angle of the space where the spray cylinder itself is located after adjusting the angle and the angle between the spray cylinder and the receiving plate changes at the same time, so it is impossible to know whether the change of the spinning effect is What kind of change is caused by

Again, it is necessary to turn the fastening handle before and after each change of angle, which is cumbersome to operate and affects the efficiency of the experiment, and the positioning of the adjusting gear after opening the fastening handle lacks constraints, which easily affects the positioning accuracy

In addition, the spray angle can only be adjusted in the range of 90º, and the angle adjustment has limitations
