Abstract

The invention relates to the technical field of melt-blown fabric production and manufacturing machinery, in particular to high-toughness melt-blown non-woven fabric manufacturing equipment which comprises a screw extrusion device, a spray head and a cleaning assembly. The screw extrusion device is communicated with the spray head; non-woven fabric raw materials are spirally conveyed to the sprayhead through the screw extrusion device so as to be sprayed out; and the cleaning assembly comprises an outer cylinder set, an inner cylinder set and an air sweeping mechanism. The cleaning assembly is arranged between the screw extrusion device and the spray head, and the cleaning assembly is used for switching an external air source for supplying air to the spray head, so that when the screw extrusion mechanism and the spray head stop working, air provided by the external air source can be filled into the cleaning assembly through an airtight channel; and then the raw materials remaining inthe spray head are extruded out of the spray head through the air, so that manual disassembly and maintenance are not needed, cleanliness of the interior of the spray head is guaranteed, and the technical problem that the raw materials of the spray head in manufacturing equipment are blocked is solved.

Description

technical field [0001] The invention relates to the technical field of melt-blown fabric production and manufacturing machinery, in particular to a high-toughness melt-blown non-woven fabric manufacturing equipment. Background technique [0002] Meltblowing is a method for forming nonwoven meltblown fabrics of thermoplastic (co)polymer fibers. In a typical melt blown process, one or more thermoplastic (co)polymer streams are extruded through a die containing densely arranged spinneret holes and attenuated under the action of a converging flow of high-velocity hot air to form microfibers, which are Collected to form a meltblown nonwoven meltblown fabric. [0003] However, during the production and processing process of existing production equipment, when shutting down for maintenance or suspending production, the raw materials remaining in the nozzle will block the pores in the nozzle. The uniformity cannot be guaranteed, and the spray head needs to be disassembled, maintai...
