Abstract

The invention discloses a method for extruding a melt-blown cloth, which comprises extruding a melt-blown liquid by using a screw barrel of a melt-blown cloth extruder. The melt-blown liquid in the barrel is extruded in large quantities, the central rotating shaft is reversed for 20 seconds, the rotation of the central rotating shaft is stopped for 1 minute, and after the melt-blown liquid remaining in the barrel is refluxed and polymerized, repeat two more times. After the above operations, all the melt-blown liquid in the barrel is fully extruded, and then stopped. Compared with the prior art, the present invention can solve the problems that the existing melt-blown cloth extrusion method has poor extrusion effect on the melt-blown liquid and affects the extrusion efficiency.

Description

technical field [0001] The invention relates to the technical field of medical mask production equipment manufacturing, in particular to a melt-blown liquid extrusion method for a melt-blown cloth extruder. Background technique [0002] Existing melt-blown liquid extrusion methods for melt-blown cloth extruders generally use a melt-blown cloth extruder with a screw barrel to extrude the melt-blown liquid, and this screw barrel is generally Including the barrel of the screw jacket, the central axis of the screw and the helical thread section are made of the same metal material. This kind of screw generally uses a round rod with a large diameter to process the helical thread section by fine grinding, so the axial direction of the helical thread section is The cross section is generally a rectangle perpendicular to the axial centerline of the central rotating shaft, that is, including the working face, the top face and the back of the working face for extruding the melt-blown l...
