A kind of toughness meltblown non-woven fabric manufacturing equipment

Abstract

The invention relates to the technical field of melt-blown cloth production and manufacturing machinery, in particular to a tough melt-blown non-woven fabric manufacturing equipment, which comprises a screw extruding device and a spray head that are connected in communication, and the non-woven fabric raw materials are screwed through the screw extruding device. It is sprayed to the spray head, and also includes a cleaning assembly. The cleaning assembly includes an outer cylinder group, an inner cylinder group and an air sweeping mechanism. By using a cleaning assembly between the screw extrusion device and the spray head, the cleaning The assembly switches the external air source that supplies air to the ejection head, so that when the screw extrusion mechanism and the ejection head stop working, the gas provided by the external air source can be filled into the interior of the cleaning assembly through the airtight channel. Then, by using gas to extrude the raw materials remaining in the spray head from the spray head, there is no need to manually disassemble and maintain, to ensure the cleanliness of the inside of the spray head, and to solve the technical problem of clogging of the material spray head in the manufacturing equipment.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth production and manufacturing machinery, in particular to a 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 meltblowing process, a stream of one or more thermoplastic (co)polymers is extruded through a die containing densely packed spinneret orifices and attenuated under the action of a converging stream of high velocity hot air to form microfibers, which are Collected to form a meltblown nonwoven meltblown cloth. [0003] However, during the production and processing process of the existing production equipment, when the maintenance or production is stopped, the raw materials remaining in the spray head will block the pores in the spray head. The uniformity cannot be guaranteed, and the spray head needs to be disassembled, maintain...

AI Technical Summary

Problems solved by technology

[0006] In view of the above problems, the present invention provides a kind of tough melt-blown non-woven fabric manufacturing equipment, by using a cleaning assembly arranged between the screw extruder and the spray head, and using the cleaning assembly to clean the air supply to the spray head. The air source is switched so that when the screw extrusion mechanism and the spray head stop working, the gas provided by the external air source can be filled into the interior of the cleaning assembly through the airtight channel, and then the residual gas in the spray head will be removed by using the gas. The raw material is extruded from the spray head, without manual disassembly and maintenance, to ensure the cleanliness of the inside of the spray head, and to solve the technical problem of material blockage of the spray head in the manufacturing equipment
