Non-woven fabric melt-blowing forming method

Abstract

The invention relates to a non-woven fabric melt-blowing forming method. A roller receiving device is adopted. The roller receiving device comprises a base plate, an installing frame, a receiving roller and a cleaning mechanism. The specific method for treating a melt-blowing non-woven fabric by adopting the roller receiving device comprises the steps of polymer feeding, melt extrusion, fiber forming, net forming and roller cleaning. The receiving roller comprises a rotating motor, a rotating cylinder, an inner cylinder, a rotating rod, a driving motor, an air pump and a filter module. The filter module comprises a rotating ring, a filter cloth, a driven gear ring and a driving gear ring. The cleaning mechanism comprises a lifting air cylinder, a lifting plate, a bearing plate, a cleaningbrush, a rotating motor, a rotating cam and a connecting sliding block. The air pump and the external environment are isolated through the filter module, the phenomenon that normal work of the air pump is affected due to the fact that external impurities enter a pipeline, and the pipeline is blocked can be effectively avoided, and the surface of the receiving roller can be cleaned through the cleaning mechanism so as to ensure the receiving quality.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production, in particular to a non-woven fabric melt-blown forming method. Background technique [0002] The melt-blowing method uses high-speed hot air flow to rapidly and high-magnify the high-power stretching and solidifying spinning method of the newly extruded polymer melt. The advantage is that the process flow is short, and it can be directly made into non-woven fabrics by spinning. In the melt-blown nonwovens production line, it is necessary to use a receiving device to receive the fibers produced by the spinning system and form a nonwoven web. [0003] At present, according to the carrier used to receive the fiber web, the receiving device is mainly divided into two types in technology: one is to use the roller to receive, which is mainly used for the independent melt blown nonwoven production line, especially for some small width Melt-blown system; the other is to use mesh bel...

Problems solved by technology

[0005] a. During the winding process, an air pump and other devices are often connected inside the receiving drum to assist the receiving drum to wind the non-woven fabric into a net. During the working process of the air pump, it is easy to suck external dust, melt, etc. into the pipeline, resulting in The pipeline is blocked, which affects the normal operation of the air pump. Therefore, it is necessary to regularly disassemble the receiving drum to clean the air pump and pipeline, which is time-consuming and laborious, and the operation is difficult;

[0006] b. In order to work with the air pump, many through holes are evenly opened on the surface of the receiving drum. When the receiving drum works for a long time, molten material will adhere to the surface and the through holes of the receiving drum, and the protrusions formed by the molten material will be formed in the molten The traces on the fibers of the sprayed non-woven fabric affect the surface morphology of the melt-blown non-woven fabric and reduce the quality of the factory
