Abstract

The invention provides an extruder nozzle assembly based on melt-blown cloth preparation, and relates to the technical field of melt-blown cloth preparation. The extruder nozzle assembly comprises a nozzle, sealing bottom plates and a sealing top cover; micropores are formed in the bottom side of the nozzle, a plurality of feeding branch holes are formed in the top of the nozzle, and two hot air inlets are symmetrically formed in the left end of the nozzle; the four sealing bottom plates are arranged, and are located on the bottom side of the nozzle; a feeding main hole is formed in the top of the sealing top cover, and the sealing top cover is located on the top side of the nozzle; two bases are arranged and connected to the left end and the right end of the nozzle correspondingly; a screw rod is connected to the top of each base, a driving block is connected with each screw rod, and a screw hole is formed in each driving block. According to the width of the melt-blown cloth needing to be prepared, the sealing bottom plates are installed at the left end and the right end of the bottom side of the nozzle, the micropores in the bottom side of the nozzle are blocked through the sealing bottom plates, the spraying width of the nozzle is adjusted, and therefore, the preparation requirements of the melt-blown cloth with different widths are better met.

Description

technical field

[0001] The invention belongs to the technical field of melt-blown cloth preparation, and more specifically relates to an extruder nozzle assembly prepared based on melt-blown cloth. Background technique

[0002] Melt-blown cloth, melt-blown cloth uses polypropylene as the main raw material, and the fiber diameter can reach 1-5 microns. These ultra-fine fibers with a unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt-blown cloth has excellent Excellent filterability, shielding, heat insulation and oil absorption, can be used in air, liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials and wiping cloths and other fields.

[0003] The extruder nozzle assembly prepared by melt-blown cloth can refer to patent CN212335362U, which mainly includes a main body and a filter module. The main body includes a first cavity and an opening inside, and the filt...
