[0025] A multi-functional spinning device, its structural device diagram is as follows figure 1 Shown: consists of melt extruder 1, spinning pump 2, microflow pump 3, needle 4, controller 5, moving platform 6, moving platform motor 7, spinneret 8, curing device 9, receiver 10, receiving The receiver motor 11 and the syringe 12 are composed; the receiver motor 11 is connected with the receiver 10 through a clamping device to drive the receiver 10 to rotate, and a curing device 9 is arranged above the receiver 10 side, directly above the curing device 9 There is a spinneret 8, and the spinneret 8 is welded under the spinning pump 2, and the spinning pump 2 is welded to the melting extruder 1, and there is a needle 4 on the other side of the receiver 10, and the needle 4 is connected to the microflow pump 3. The syringe 12 is welded; the spinning mode is selected through the controller 5 directly above the mobile platform machine 7; the internal circuit of the controller 5 is con...

Embodiment 2

[0027] We adjust the spinning mode by adjusting the controller 5, first adjust the spinning mode to melt spinning, then pour the spinnable polymer particles polylactic acid (PLA) from the melt extruder 1 inlet, and The melting temperature of the polymer is adjusted on the panel to be 170°C, the flow rate of the spinning pump 2 is 0.1ml / h, the speed of the moving platform motor 7 is set at 500μm / s, and the speed of the receiver motor 11 is 500r / s, so that the polymer PLA is heated and melted Become a melt, and the melt will flow through the spinning pump 2 connected to the right side of the melt spinning machine and enter the spinneret 8 below it (the inner and outer diameters of the spinneret are 0.3mm and 0.5mm respectively), forming A thin stream of liquid flows out of the spinning channel and passes through the solidifying device 9 below the spinneret 8 to be solidified into fibers, and the fibers are wound on the receiver below the solidifying device 9 by the action of trac...

Embodiment 3

[0029] We adjust the spinning mode by adjusting the controller 5, first the spinning mode is adjusted to melt spinning, then the spinnable polymer particle polymethyl methacrylate (PMMA) is poured from the melt extruder 1 inlet, and On the panel of the controller 5, the temperature of polymer melting is adjusted to be 120°C and the flow rate of the spinning pump 2 is controlled at 3ml / h, the speed of the moving platform motor 7 is set at 2000 μm / s, and the speed of the receiver motor 11 is 4000r / s, so that the polymerization The material PMMA is heated and melted into a melt, and the melt will flow through the spinning pump 2 connected to the right side of the melt spinning machine and into the spinneret 8 below it (the inner and outer diameters of the spinneret are 0.5mm, 0.7mm, respectively. ), forming a thin stream of liquid, which flows out of the spinning channel and passes through the curing device 9 below the spinneret 8 to be solidified into fibers, and the fibers are w...

Description

technical field [0001] The invention relates to a spinning device and process for preparing ordered nanofiber arrays, more specifically a composite device and process capable of both melt spinning and microfluid spinning. Background technique [0002] The spinning process is a process for realizing various microchemical preparations of fibers, and is widely used in biological tissues, textile industry, supercapacitors and wearables. At present, the commonly used spinning processes are mainly electrospinning, melt spinning and centrifugal spinning. Among all these spinning processes, electrospinning is the most widely used due to its wide range of spinnable polymers and the small diameter of the spun fibers. However, electrospinning can only spray conductive polymer solution or melt in a strong electric field. When spinning a viscous or nearly insulating polymer solution, it is difficult to overcome the surface tension to form a jet stream, and it cannot collect various mate...
