Nano fiber net forming device

Abstract

The invention relates to a nano fiber net forming device. The nano fiber net forming device comprises a rack, a spinning mechanism, a tightening mechanism and a control mechanism, wherein the spinning mechanism comprises a hopper, a metering channel, a first spinning channel, a second spinning channel and high-pressure nozzles; the metering channel is fixed on the rack; one end of the metering channel is communicated with the hopper and the other end of the metering channel is horizontally provided with a first branch opening and a second branch opening; the first branch opening is communicated with the first spinning channel and the second branch opening is communicated with the second spinning channel; a first fiber nozzle is arranged at the bottom of the first spinning channel and a second fiber nozzle is arranged at the bottom of the second spinning channel; the two high-pressure nozzles are communicated with the first spinning channel and the second spinning channel respectively. The nano fiber net forming device is simple in structure and convenient to operate; nano fibers can be rapidly and effectively collected to form a net and can be laminated into a multilayered structure in one step; the cost is low and the air permeability is good; meanwhile, the filtering performance is very good and the applicable range is wide; the nano fiber net forming device can be applied to all fields of the modern society.

Description

technical field [0001] The invention relates to a nanofiber collecting and forming technology, in particular to a nanofiber forming device. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. [0003] Various existing web forming devices either use a dust cage drum and can only be used for fluff fibers with a fiber length of 1 to 3 mm, or use a needle roller and can only be used for cotton wool fibers with a fiber length of 25 to 60 mm. Moreover, the structure is also complicated, and only a single layer can be formed into a net. Th...

[0003] Various existing web forming devices either use a dust cage drum and can only be used for fluff fibers with a fiber length of 1 to 3 mm, or use a needle roller and can only be used for cotton wool fibers with a fiber length of 25 to 60 mm. Moreover, the structure is also complicated, and only a single layer can be formed into a net. The air permeability and filterability of the resulting finished product cannot meet the needs of modern society, and the cost is relatively high.
