Embodiment 1

[0049] see Figure 1 to Figure 4 , a two-way collection system for centrifugal spinning, comprising an air jet ring plate 2, a bottom collecting portion 3 and a longitudinal collection rod 4; the air jet ring plate 2 is a hollow structure, including a top ring plate 21, a bottom ring plate 22 and a The outer ring wall 23, the inner ring wall 24 between the two, the top ring plate 21, the outer ring wall 23, the bottom ring plate 22, and the inner ring wall 24 together form the same ring disc cavity 25, and the inner ring wall 24 encloses An inner ring cavity 241 with upper and lower openings, the top ring plate 21 is provided with a plurality of ejection air holes 251 communicating with the inner cavity 25 of the ring disc, and an inserting rod barrel 5 is arranged inside the inner cavity 25 of the ring disc. The top of the rod barrel 5 is connected with the upper rod opening 211 provided on the top ring plate 21, and the bottom end of the inserting rod barrel 5 is connected w...

Embodiment 2

[0051] Basic content is the same as embodiment 1, the difference is:

[0052] The top and the bottom of the vertical collecting rod 4 are vertically connected with the upper limit plate 41 and the lower limit plate 42 respectively, the width of the upper limit plate 41 is greater than the width of the top ring plate 21, and the width of the lower limit plate 42 is greater than The diameter of the lower rod port 221. The upper limit plate 41 is circular, and the ejection air holes 251 on both sides of the upper rod opening 211 are respectively the No. 1 air hole 252 and the No. 2 air hole 253. The No. 1 air hole 252, the No. 2 air hole 253 and the upper limit plate 41 are on the top The projections on the ring plate 21 contact each other to form a first contact area 411 and a second contact area 412; the connection between the lower limit plate 42 and the bottom end of the longitudinal collecting rod 4 is a flexible connection. Preferably, the area of ​​the first contact area ...

Embodiment 3

[0054] Basic content is the same as embodiment 1, the difference is:

[0055] The longitudinal collecting rod 4 is a hollow structure, the inside of the longitudinal collecting rod 4 is provided with a coaxial longitudinal rod inner chamber 43, and the rod wall of the longitudinal collecting rod 4 is provided with a longitudinal rod air hole 44 communicating with the longitudinal rod inner chamber 43, A lower plate hole 421 communicating with the inner cavity 43 of the longitudinal rod is defined in the middle of the lower limiting plate 42 .

Abstract

The invention provides a two-way collecting system for centrifugal spinning. The system comprises a jet ring disk, a bottom collecting part and a vertical collecting rod, wherein the jet ring disk comprises a top ring plate, a bottom ring plate, an outer ring wall and an inner ring wall, the top ring plate is provided with a plurality of jacking vents communicated with an inner cavity of the ring disk, an insertion rod cylinder is arranged in the inner cavity of the ring disk, the vertical collecting rod penetrates through the inner portion of the insertion rod cylinder, the vertical collecting rod and the insertion rod cylinder relatively slide vertically, the bottom collecting part is arranged below the jet ring disk, the top of the bottom collecting part is connected with the bottom of the inner ring wall, the bottom of the bottom collecting part extends downward, the inner portion of the bottom collecting part is provided with a bottom collecting cavity communicated with an inner ring cavity, and a centrifugal spinning head is arranged directly above the inner ring cavity. The two-way collecting system for centrifugal spinning not only has a stronger guiding effect, but also has a better collecting effect, can perform two-way collection of the side and the bottom, and has a better thread removing effect.

Description

technical field [0001] The invention relates to a centrifugal spinning collection device, which belongs to the technical field of textiles, in particular to a two-way collection system for centrifugal spinning, which is particularly suitable for enhancing the guiding performance and improving the collection effect. Background technique [0002] Nanofibers refer to ultrafine fibers with a diameter of tens to hundreds of nanometers, which have unique advantages that other fibers cannot possess, such as very large specific surface area, ultrafine porosity, and good mechanical properties. In recent years, nanofibers have been widely used in textile materials, tissue engineering scaffolds, drug delivery, filter media, artificial blood vessels, biochips, nanosensors, optics, composite materials and other fields. [0003] There are many methods for preparing nanofibers in the prior art, such as stretching, microphase separation, template synthesis, self-assembly, electrospinning, c...
