Embodiment Construction

[0020] Such as image 3 As shown, the two-component melt-blown equipment of the preferred embodiment of the present invention includes a melt-blown device 1 , a fiber supply device 2 to be mixed, a needling device 3 , and a web-forming device 4 .

[0021] The melt-blowing device 1 comprises a spinneret 11, and the spinneret 11 comprises a spinneret 12 fixedly mounted on the bottom of the spinneret 11, and the spinneret 12 has several spinneret holes. The melt-blowing device 1 uses high-speed hot air to draw the thin stream of polymer melt extruded from the spinneret hole of the spinneret die 11, thereby forming ultra-fine melt-blown fibers.

[0022] The fiber supply device 2 to be mixed includes a feeding air duct 21 and a fan 22 . The material conveying channel 21 has a material outlet 21a. When the blower fan 22 rotates, it generates wind along the material conveying air channel 21 and blows toward the material outlet 21a. Under the action of wind force, the fibers to be ...

Abstract

A kind of two-component melt-blown equipment provided by the present invention comprises a melt-blown device, a fiber supply device to be mixed, and a web-forming device. The melt-blown device includes a spinneret die and a spinneret, and the spinneret is fixed on the side of the spinneret die. Below, the spinneret has several spinneret holes for spraying melt-blown fibers. The fiber supply device to be mixed includes a feeding air duct and a fan. The fiber to be mixed and the melt-blown fiber provided by the fiber supply device to be mixed are melted The vertical wind force provided by the spray device and the horizontal wind force generated by the fan are mixed to form mixed spray fibers, and a needle punching device is also included. The needle punch device is arranged below the melt blown device and the fiber supply device to be mixed, and Above the web forming device, the needle punching device includes a pair of rotatable needle punching rollers, which are respectively arranged on both sides of the co-sprayed fiber, and each needle punching roller contains a plurality of needles. The mixed-blown fibers and fiber layers produced by the two-component melt-blown equipment have better mixing uniformity and transverse tensile strength.

Description

technical field [0001] The invention relates to the field of melt-blown nonwoven fabrics, in particular to two-component melt-blown equipment. Background technique [0002] The two-component melt-blown process is to mix the melt-blown ultra-fine short fibers and conventional fibers online, and realize one-time web formation to produce two-component melt-blown nonwovens. [0003] Such as figure 1 As shown, in the existing two-component melt-blown equipment, the melt-blown device 1' uses high-speed hot air to draw the polymer melt fine stream extruded from the spinneret hole of the spinneret die 11', thereby forming a super Fine meltblown fibers. The to-be-mixed fiber supply device 2' transports the to-be-mixed fiber to the discharge port 23' of the feeding air duct 22' through the wind force of the fan 21', and the melt-blown fiber and the to-be-mixed fiber are mixed under the two-way wind force. [0004] However, in the above-mentioned existing two-component melt-blown eq...
