Abstract

The invention discloses a control system and method for a continuous-nanometer-fiber medical yarn device. The system includes an acquisition device, an upper computer, a controller, a high-voltage generator, an air-feeding fan, an exhaust fan, thermic lances, a peristaltic-pump module and motor modules. The acquisition device is connected with the upper computer. The controller is connected with the upper computer, the high-voltage generator, the air-feeding fan, the exhaust fan, the thermic lances, the peristaltic-pump module and the motor modules. The control system and method for the continuous-nanometer-fiber medical yarn device is applied to nanometer-fiber medical operation line production in domestic hospitals and related-device manufacturing so that a current situation that domestic high-performance operation lines are all depending on import is changed and low-end non-biodegradable operation yarns are eliminated gradually and thus pains of an operation patient are alleviated. Targeted at problems of low efficiency and complex process and the like of current medical yarn technologies, through motion trail modeling of the injected nanometer fiber, the control system controls precisely the whole collection process of the nanometer fiber so that high efficiency and uniformity of collection of the medical nanometer fiber are realized.

Description

[0001] technical field [0002] The present invention relates to the field of medical yarn equipment control, and more particularly, to a continuous nanofiber medical yarn equipment control system and method. Background technique [0003] At present, the collection methods of continuous electrospun nanofibers at home and abroad are very single, that is, they are all collected in the form of non-woven webs. However, due to the unstable "whip" state of the jet during the spinning process, the fibers on the receiving device The arrangement of nanofibers is often chaotic, and the final nanofibers are similar to a net. The utilization of nanofibers requires a second process, which is inefficient. The key to the above problems is that it is difficult to control the trajectory of electrospun nanofibers, and no device is used to optimize the trajectory of the prepared nanofibers, which severely limits the development prospects of continuous electrospun nanofibers.
