Example Embodiment

[0040] Embodiment 1: A kind of non-woven fabric manufacturing equipment that takes melt-blown as carrier and ultra-short fiber to mix, as figure 1As shown, it includes a meltblown device 1 and a feeding device. The melt-blowing device 1 comprises a collection box 11, a screw extruder 12, a metering pump 13, a spinning box 14 and a spinneret 142 connected in sequence, and the spinneret 142 is provided with a spinning nozzle for easy extrusion of spinning. hole. At the same time, a traction air duct 141 is provided at the spinneret 142, one end of the traction air duct 141 can be connected with a blower (not shown in the figure), and the other end is located at the spinneret hole; and the traction air duct 141 is distributed in the spinneret hole The two sides are arranged symmetrically.

[0041] The feeding device includes two airtight storage tanks 2 , which are arranged symmetrically on both sides of the spinning box body 14 . The cross-section of the airtight storage tank...

Example Embodiment

[0048] Embodiment 2: as image 3 As shown, the difference from Example 1 is that the non-woven fabric manufacturing equipment that uses melt-blowing as a carrier mixed with ultra-short fibers also includes an airtight auxiliary feeding storage tank 6, an airtight auxiliary feeding storage tank 6 and an airtight storage The tanks 2 are connected by pipelines, and the pipelines include a feed pipeline 62 and an air pressure equalization pipeline 63 . Airtight auxiliary feeding storage tank 6 can be one, and now feed pipeline 62 is Y-shaped, connects two airtight storage tanks 2 respectively, and electromagnetic valve can be set on feed pipeline 62; Air pressure balance pipeline 63 is two, The air pressure in the airtight auxiliary feeding storage tank 6 and the air pressure in the two airtight storage tanks 2 are balanced by two air pressure balance pipelines 63, so that ultra-short fibers enter from the feed pipeline 62, and the air pressure balance pipeline 63 is set There is...

Example Embodiment

[0050] Embodiment 3: as Figure 4 As shown, compared with Embodiment 1, the difference is that the draft air duct 141 is formed by clamping the side wall of the spinning box 14 and the side wall of the airtight storage tank 2 .

Abstract

The invention discloses a device and method for manufacturing a non-woven fabric by mixing a melt-blown subject as a carrier and short cut fibers. According to key points of the technical scheme, the non-woven fabric comprises a melt-blown device and a feeding device. The melt-blown device comprises a traction air flue and a spinneret plate located at one end of the traction air flue. The traction air flue is located on one side close to the feeding device, the feeding device comprises a sealed storage tank, one end of the sealed storage tank close to the spinneret plate is provided with a feeding port, a damping device is arranged at the position of the feeding port, and the feeding device further comprises a pressurization device which pushes ultra short fibers to flow to the feeding port, so that the ultra short fibers overcome resistance of the damping device to be squeezed out of the sealed storage tank. The device achieves the effects that product process requirements are met, the working environment can be ensured, and the cost is low.

Description

technical field [0001] The invention relates to the field of non-woven fabric manufacturing, in particular to a non-woven fabric manufacturing equipment and method using melt blown as a carrier and mixing ultra-short fibers. Background technique [0002] Short fiber (short fiber), also known as cut fiber, is a chemical fiber long fiber bundle that is cut or broken into fibers equivalent to the length of various natural fibers. Short fiber limit, the length is generally 35 ~ 150mm. According to the specifications of natural fibers, they can be divided into short fibers such as cotton type, wool type, carpet type and medium and long type. They can be spun purely or blended with different proportions of natural or other fibers to make sliver, fabric and felt. And there are some natural fibers whose length is less than 35mm, such as kapok fiber, the general length is 8-32mm, and wood pulp fiber, the general length is 2.56-4.08mm, these lengths are shorter than short fibers Th...
