Abstract

The invention discloses a melt-blown fabric manufacturing device and a melt-blown fabric manufacturing method. The melt-blown fabric manufacturing device comprises an extruder (1), a plurality of meltpumps (2) and a plurality of melt-blowing die heads (3), wherein the plurality of melt pumps (2) respectively communicate with the output end of the extruder (1); and the plurality of melt-blowing die heads (3) respectively communicate with the melt pumps (2), and the extruder (1) is a double-screw extruder or a multi-screw extruder. According to the melt-blown fabric manufacturing device, a PP raw material can be directly machined into melt-blown fabric, the using of a single-screw extruder for secondary heating is not needed, so that the production efficiency is improved, one line can be matched with multiple groups of die heads, so that the efficiency is improved by several times, meanwhile, starting can be realized by one person, and thus labor is saved. According to the technical scheme, the use of the single screw for secondary heating in the traditional process is saved, the performance of materials is further kept, meanwhile, a set of single-screw device is saved, moreover, one extruder is matched with two or more melt-blown fabric production lines, thus energy conservation and emission reduction are realized, the structure is simple, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth manufacturing, in particular to a manufacturing device and method for melt-blown cloth. Background technique [0002] The existing melt-blown cloth manufacturing device includes at least two extruders. Through one extruder, the PP raw material suitable for manufacturing melt-blown cloth is extruded and granulated through a die. The rear end is equipped with a water tank, an air dryer, and a pelletizer. Cut the material into granules to prepare special granules for melt blowing. Then the size is selected by vibrating sieving, and then packed in the back to complete the packaging of the particles. Then the melt-blown special pellets are heated to a molten state through a single-screw extruder before the melt-blown cloth is manufactured. The existing technology requires secondary heating, which degrades the performance of the material and increases the production cost. The single-line pro...
