Reciprocating type continuous roller receiving device capable of being used for electrostatic spinning

Abstract

The invention discloses a reciprocating type continuous roller receiving device capable of being used for electrostatic spinning. The device comprises a first non-woven yardage roll, and a coiled material on the first non-woven yardage roll sequentially passes through a receiving roller and a spring; the device is characterized in that the space between the first non-woven yardage roll and the receiving roller as well as the space between the receiving roller and the spring are each provided with one or more auxiliary rollers, the auxiliary rollers and the receiving roller can perform reciprocating motion in the horizontal direction, and after passing through the auxiliary rollers, the receiving roller and the spring, the coiled material on the first non-woven yardage roll and a coiled material on a second non-woven yardage roll are both delivered to a winding roller for winding through a conveying belt. According to the reciprocating type continuous roller receiving device, nanofibers can be adsorbed to the surface of received cloth in the rotating direction of the rollers, and no filament connection or filament sticking phenomenon is caused. By selecting appropriate spinning equipment, nanofiber membranes narrow in diameter and pore size distribution and small in diameter can be produced, and the problems that in the prior art, uniformity is poor, intermittent production is conducted, and filament connection and filament sticking are caused are effectively improved.

Description

technical field [0001] The invention belongs to the field of continuous production of electrospinning equipment, and in particular relates to a reciprocating continuous drum receiving device that can be used for electrospinning. Background technique [0002] The unique size effect and surface effect of nanofibers endow related products with excellent performance, and have potential application value in many fields such as air filtration, water filtration, biomedical materials, and battery separators. Among the preparation methods of nanofibers, the electrospinning method is simple and easy to operate, and the products that can be spun are diversified, and it is recognized as the most competitive processing method. However, the traditional needle-type electrospinning machine has low production capacity and extremely low output, which has become the main technical obstacle for the industrialization of nanofibers prepared by electrospinning hair. At present, both at home and a...

Problems solved by technology

There are two reasons. One is that the produced nanofibers have a large thickness unevenness, and there are beads and defects on the surface of the nanomembrane, and the uniformity is poor; the other is that it is difficult to realize the continuous production of nanofibers.

[0003] The electrospinning line equipment (YT-MC-I type) developed by the Lintong Laboratory of Deakin University in Australia and the Nanospider series equipment of the Czech Elmarco company use a planar receiving device to achieve continuous production of nanofibers. This series of equipment has a high degree of recognition of spinning devices and spinning materials (solutes and solvents), and is expensive, and the products developed by this series of equipment have not been marketed.

For example, the YT-MC-I spinning machine is mainly suitable for spinning polyvinyl alcohol. If other materials are used or the spinneret is replaced, the phenomenon of continuous filaments and hanging filaments will occur, which will seriously affect the quality and application of nanomaterials.
