Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete. It should be noted that the terms "first" and "second" in the present invention do not denote any particular quantity or order, but rather are used for distinguishing names.

Referring to fig. 1, in this embodiment, a production apparatus for fluffy meltblown material includes a meltblown die head 1, two web rolls 2, an arc transition plate 3, a web former 4 and a pair of rolls 5, wherein the meltblown die head 1 is used for ejecting meltblown fibers, cooling air ducts 11 are disposed on both sides of an outlet of the meltblown die head 1 (the cooling air ducts 11 are connected to a blower, not shown in the figure), air outlets of the two cooling air ducts 11 are disposed opposite to each other below the outlet of the meltblown die head 1, so as to respectively blow low-temperature cooling air from both sides, and cool and draft the ejected meltblown fibers by the low-temperature cooling air.

In this embodiment, the two web rotary rolls 2 are symmetrically arranged at two sides of the position below the meltblowing die head 1, and the suction areas of the two web rotary rolls 2 are arranged oppositely (the suction area of the embodiment is aligned with the outlet of the meltblowing die head 1), wherein, the web rotary roll 2 of the embodiment comprises a cylinder 21 and an inner container 22 fixedly arranged in the inner cavity of the cylinder 21, the inner container 22 is provided with a suction air port extending along the axial direction thereof (the suction air port of the embodiment is communicated with a blower at a span of 45 DEG in the circumferential direction), a plurality of air holes are arranged on the circumferential surface of the cylinder 21, so that the suction area with suction negative pressure is formed at the overlapped position of the cylinder 21 and the suction air port by the suction effect of the suction air port, therefore, the suction air ports of the two web rotary rolls 2 are the same, the meltblown fibers ejected from the meltblowing die head 1 pass through between the two web rotary rolls 2, and under the suction negative pressure effect of the two web, thereby leading the melt-blown fiber to be drawn towards the two sides in the falling process, and further achieving the purpose of increasing the thickness and the bulkiness of the melt-blown fiber.

In this embodiment, the annular transition plate is located below the web roll 2 and the outlet of the arc-shaped transition plate 3 is arranged adjacent to the web former 4, and the arc-shaped transition plate 3 is used for receiving the falling melt-blown fibers and transferring the melt-blown fibers onto the web former 4 along the arc-shaped conveying surface of the arc-shaped transition plate 3.

Further, the back of the annular transition plate of the embodiment is provided with a negative pressure suction box 31, a negative pressure port of the negative pressure suction box 31 faces the back of the annular transition plate, wherein the arc-shaped conveying surface of the annular transition plate is provided with a plurality of fine meshes, so that the melt-blown fibers falling onto the annular transition plate are attached to the arc-shaped transition surface under the negative pressure action of the negative pressure suction box 31 and gradually transferred to the web forming surface of the web forming machine 4 to form a web forming layer.

In this embodiment, a pair of rollers 5 are arranged closely up and down and the rollers 5 are located at the downstream of the web former 4, wherein the meltblown fiber layer processed by the web former 4 passes through the roller surface gap between the two rollers 5, so that the roller action of the two rollers 5 is utilized to perform surface calendering on the meltblown fiber layer to reduce fiber fly-overs, and the calendered meltblown fiber layer is wound up by the wind-up roller.

Further, the roller 5 of the embodiment adopts a smooth roller structure, and the roller surface of the smooth roller structure is a Polytetrafluoroethylene (PTFE) coating, so that the roller surface of the roller 5 has the characteristic of non-sticking, and the roller 5 is prevented from being adhered with melt-blown fibers in the calendering process.

In the embodiment, the wind temperature of the low-temperature cooling wind is 12-30 ℃, and can be adjusted adaptively according to actual production requirements, which is not limited herein.

In this embodiment, the center distance between the two web rotary rollers 2 can be adjusted according to the actual production requirements, so as to adapt to different melt-blown fiber thickness requirements, that is, when the center distance between the two web rotary rollers 2 is long, the negative pressure effect of the two web rotary rollers 2 on the melt-blown fibers is small, and the processed melt-blown fibers are thin; on the contrary, when the center distance between the two net rotary rollers 2 is short, the negative pressure effect of the two net rotary rollers 2 on the melt-blown fiber is large, and the processed melt-blown fiber is thick.

The above-described embodiments are merely preferred embodiments of the present invention, which are not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents of the embodiments of the invention without departing from the scope of the invention.
