Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
The electrostatic spinning phase compensation lapping control system disclosed by the embodiment comprises double-nozzle four-module phase compensation lapping, and the double-nozzle four-module phase compensation lapping adopts a transverse-laying and direct-taking net forming mode. The 4 groups of spray head group modules control the organization of the multiple spray heads to move in a staggered manner through the phase compensation control system, and the spray heads reciprocate back and forth relative to the cloth surface with a phase difference of 90 degrees in a transverse laying and straight-taking laying manner to ensure the uniformity of the fiber web according to the spinning uniformity. The system simulation is carried out on the movement of the 4 groups of spray heads, and each parameter in the actual engineering problem can be accurately obtained.
The human-computer interaction interface of the phase compensation control system comprises a working area, a display area and a control area, wherein: setting motion parameters by a user through the control area, wherein the motion parameters comprise the position of the spray head, the diameter of the spray head, the distance between the spray heads and the motion speed of the base cloth; the working area reflects the actual movement condition of the spray head and is adjusted by setting the parameters of the control area; the display area reflects the actual forming condition of the fiber web and monitors the web laying condition in real time.
The working process of the invention is divided into three stages:
in the first stage, as shown in fig. 1, parameters of the spinning simulation are input into a function according to the parameter design and adjustment results, the whole simulation process is run, the movement of the second group of nozzles is started when the former nozzle of each group of nozzles moves to half of the whole working interface and the similar phase difference is 90 degrees, and so on.
In the second stage, as shown in fig. 2, after the spinning uniformity simulation system is operated, the threads designed by each group of nozzles are sequentially started, the spinning effect is updated in a display area in real time according to the set parameters, the areas of the nozzles in different groups are relatively uniform, and the integrity of spinning is relatively good.
In the third stage, as shown in fig. 3, as the spinning simulation proceeds and the display area is continuously updated, the display area can be gradually seen to initially display the simulated spinning effect. Different colors can be connected together completely, and the initial spinning effect is realized ideally.
