Problems solved by technology
The process of melt-blown fiber forming: polymer feeding→melt extrusion→fiber formation→fiber cooling→web forming→bonding (fixed net)→cutting and winding→finishing or special finishing Among them, the melt blown die head The function is to transform the viscous polymer melt or solution into a fine flow with a specific cross-section through the micropores, and form filaments after being solidified by a coagulation medium such as air or a coagulation bath. The air passages of the stretched melt are usually arranged symmetrically and evenly with each other, but due to various differences, the flow velocity of the two symmetrical air passages is different, causing the fibers to deflect during cooling, which seriously affects the strength of the fibers and the cloth-forming effect

Abstract
The invention discloses a fiber spinning melt-blowing die head and a fiber spinning method. The melt-blowing die head comprises a first die head and a second die head, wherein a spinneret orifice passage is arranged between the first die head and the second die head; a first air knife gas passage is arranged in the first die head; a second air knife gas passage is arranged in the second die head;a connecting air pipe communicates between the side face of the first air knife gas passage and the side face the second air knife gas passage; a first anti-aeration plate and a second anti-aeration plate are respectively arranged in the first air knife gas passage and the second air knife gas passage; a first connecting rod and a second connecting rod are hinged onto the first anti-aeration plateand the second anti-aeration plate; a first piston and a second piston located in the connecting air pipe are arranged at the tail ends of the first connecting rod and the second connecting rod; a sealed cavity is arranged between the first piston and the second piston; and when the gas flow rates of the first air knife gas passage and the second air knife gas passage are different, the first anti-aeration plate and the second anti-aeration plate are driven to enable the flow rates of the first air knife gas passage and the second air knife gas passage to be the same.
Description
technical field [0001] The invention relates to the field of fiber spinning. Background technique [0002] Jet spinning refers to the spinning method in which the polymer solution or melt extruded from the spinneret hole is directly sprayed and stretched by means of high-speed hot air flow, and solidified into fibers. The process of melt-blown fiber forming: polymer feeding→melt extrusion→fiber formation→fiber cooling→web forming→bonding (fixed net)→cutting and winding→finishing or special finishing Among them, the melt blown die head The function is to transform the viscous polymer melt or solution into a fine flow with a specific cross-section through the micropores, and form filaments after being solidified by a coagulation medium such as air or a coagulation bath. The air passages of the stretched melt are usually arranged symmetrically and evenly with each other, but due to various differences, the flow velocity of the two symmetrical air passages is different, causing...
