Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a melt-blown cloth nozzle structure that avoids airway blockage, so as to solve the problem that existing nozzles cannot filter large particles of incoming fuses during actual application. Therefore, it will cause blockage due to the entry of large particles, and it is impossible to continuously stir the raw materials after twin-screw extrusion, so it is easy to cause the raw materials to solidify due to uneven heating during ejection

Abstract

The invention provides a melt-blown cloth nozzle structure capable of avoiding air passage blockage, relates to the technical field of melt-blown cloth, and solves the problems that in the practical application process of an existing nozzle, due to the fact that relatively large particulate matter cannot be filtered for molten filaments entering the nozzle, the large particulate matter enters the nozzle to cause blockage, and raw materials are easy to solidify due to non-uniform heating during spraying since the raw materials extruded by double screws cannot be continuously stirred. The melt-blown cloth nozzle structure comprises a filament feeding mechanism; and the filament feeding mechanism is screwed at the top end of a feeding mechanism. According to the invention, limiting columns, fixed plates and nozzles can be released firstly, and then the two nozzles are unfolded to the front side and the rear side to be cleaned; and through the design, when the nozzles are accidentally blocked, cleaning operation can be rapidly carried out, round-hole-shaped air discharge of air outlets formed in the inner sides of guide blocks in an air guide mechanism is changed into air passage type air discharge, so that the purpose of drying air more quickly is achieved.

Description

technical field [0001] The invention belongs to the technical field of melt-blown cloth, and more specifically relates to a nozzle structure of a melt-blown cloth that avoids blockage of air passages. Background technique [0002] Melt-blown cloth is the core material of masks. Melt-blown cloth mainly uses polypropylene as the main raw material. The fiber diameter can reach 1-5 microns. It has many voids, fluffy structure, good wrinkle resistance, and ultra-fine fibers with unique capillary structure. Increase the number and surface area of ​​fibers per unit area, so that the melt blown cloth has good filterability, shielding, heat insulation and oil absorption, and can be used for air, liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials, In the fields of oil-absorbing materials and wiping cloths, the nozzles of melt-blown cloths are prone to clogging during processing. When the nozzles are clogged, it will cause t...
