Problems solved by technology

However, since the melt electrospinning process is highly dependent on the viscosity of the polymer melt, many thermoplastic polymers with relatively high melting point and relatively high viscosity have high requirements on the spinning device. How to ensure the melt temperature and sufficient pressure to meet the continuous Stable low flow supply, so as to realize the preparation of ultrafine fibers of such materials, is an urgent and important issue
[0003] Laser spinning can achieve rapid high-temperature plasticization of some materials such as PET, thereby preparing fibers within 1 micron, but only a single fiber can be achieved, and the temperature controllability is poor. For example, Li Congju

Example Embodiment

[0018] The present invention provides a melt electrospinning nozzle suitable for high-viscosity and high-melting polymers. Such as Figure 1-5 As shown, the spinning device mainly includes a spinning nozzle 1, a spinning nozzle set 2, a nozzle sleeve 3, a plunger 4, a weight plate 5, a heating device 6, a temperature sensor 7, and an elastic sealing ring 8. The spinning nozzle 1 and the spinning nozzle kit 2 and the upper part of the nozzle kit 2 and the nozzle sleeve 3 are all screwed together, and can be automatically centered by concentricity during installation. The plunger 4 is placed inside the nozzle sleeve 3, The upper end of the counterweight plate 5 is threadedly connected to apply pressure to the melt in the sleeve. The nozzle sleeve 3 is fixed on the spinning frame through evenly distributed bolt holes 3-1, and the heating device 6 is placed on the nozzle The periphery of the sleeve 3 can be easily disassembled. The temperature sensor 7 is placed inside the nozzle sle

Abstract

The invention discloses a melt electrostatic spinning sprayer suitable for high-viscosity high-melting-point polymers. The melt electrostatic spinning sprayer mainly comprises a spinning spraying nozzle, a spinning spraying nozzle set, a sprayer sleeve, a plunger, a counterweight plate, a heating device, a temperature sensor and an elastic sealing ring. The spinning spraying nozzle is in threaded connection with the spinning spraying nozzle set, the upper portion of the spraying nozzle set is in threaded connection with the sprayer sleeve, the plunger is arranged in the sprayer sleeve, the upper end of the plunger is in threaded connection with the counterweight plate, the sprayer sleeve is fixed to a spinning machine frame through evenly-distributed bolt holes, the heating device and the temperature sensor are connected with a temperature control box, and the elastic sealing ring is arranged between the spinning spraying nozzle and the spinning spraying nozzle set. By means of the melt electrostatic spinning sprayer, the whole spinning spraying nozzle is heated through the spraying nozzle set, a spraying nozzle outlet can be heated, the spraying nozzle can be protected at the same time, the influence of high-voltage electricity on the heating device is avoided, and better spinning technology conditions can be acquired; because pressure-type feeding is adopted, high-viscosity melt spinning can be achieved, and a broader market is provided for melt spinning.
