Embodiment

[0026] Example: Continuous collection devices for centrifugal electrospun nanofibers, such as figure 1 As shown, it includes several groups of collection mechanisms evenly distributed on the periphery of the spinning nanofiber mechanism, and each group of collection mechanisms includes a collection belt 12 driven by a transmission mechanism, and the collection belt 12 corresponds to the molten material outlet 8 on the spinning nanofiber mechanism. The position of the main collection part 121, the included angle between the plane where the main collection part is located and the rotation axis of the rotating cup 21 on the nanofiber spinning mechanism is a: 0≤a≤45 degrees. The plane where the collecting part 121 (moving direction is 11 ) is rotated on a line parallel to the tangent direction of the dissolving material outlet 8 to adjust the included angle a.

Abstract

The invention relates to a continuous collection device for nanofibers spun through centrifugation and static electricity. The continuous collection device is characterized by comprising multiple sets of collection mechanisms uniformly distributed on the periphery of a nanofiber spinning mechanism, wherein each set of the collection mechanism comprises a collecting strip driven by a transmission mechanism; the part, corresponding to a melted material outlet in the nanofiber spinning mechanism, of each collection strip is a main collecting part; the included angle alpha between the plane surface, where the main collection parts are positioned, and the rotary axis of the a rotary cup in the nanofiber spinning mechanism is not less than 0 degree and not greater than 45 degrees. The continuous collection device has the benefits as follows: the collection strips are vertically arranged on the periphery of the rotary cup, so that fiber fabrics with the same thicknesses can be collected, clipping is avoided, and the utilization ratio of material can be increased. A centrifugal spinning technology and an electrostatic spinning technology are combined organically, so that the advantage of high efficiency of the centrifugal spinning and the advantages of controllable order degree and nanofiber collection of are also achieved.

Description

technical field [0001] The invention relates to a continuous collection device for centrifugal electrospinning nanofibers. Background technique [0002] There is a rotating The conical surface makes the solution transition to the form of a film. There are grooves on the outer edge of the conical surface. At the grooves, the solution film is torn into filaments. The grooves are radially distributed, and each groove has only one solution inlet and one solution outlet, which affects the spinning efficiency and makes it difficult to realize nano-scale spinning. Moreover, the plane of the main collecting belt part corresponding to the solution outlet on the fiber collecting belt is perpendicular to the axis of rotation of the rotating body (that is, the main collecting belt part is laid on the bottom of the rotating body), and at the same time, the direction of the solution outlet on the conical surface is in the same direction as the rotating body. The axis of rotation has a c...
