Abstract
The invention belongs to the technical field of melt electrospinning equipment and relates to a portable melt electrospinning device. The main structure of the device comprises a spinneret part, a handle part, a low-voltage wire and a high-voltage wire, wherein the main structure of the spinneret part comprises a sleeve, jackscrews, a spinning nozzle, a heating rod, a guide pillar, a thread groove, an inner isolation protection sleeve, an outer isolation protection sleeve and a high-voltage electrode; the main structure of the handle part comprises a casing, a power supply module, a power line, a high-voltage static module, a motor, a fan blade, air inlet holes, heating wires, an adjusting switch, a roller bracket, an upper roller and a lower roller. A tubular rod which is prepared in advance and convenient to store, carry and install is used as a spinning raw material, the position nearby the end of the tubular rod forms melt by electric heating, the tip of the spinning nozzle with aconical structure can generate dozens of jets simultaneously, and real-time batch preparation of superfine fibers is achieved. The device is simple in structure, simple and convenient to operate, safeand reliable, convenient to carry and hold and high in integration degree and spinning efficiency.
Description
Technical field: [0001] The invention belongs to the technical field of melt electrospinning equipment, and in particular relates to a portable melt electrospinning device, which can prepare superfine fibers in batches. Background technique: [0002] Electrospinning is a process that uses high-voltage electrostatics to prepare polymer melts or solutions into ultrafine fibers. It has the characteristics of simple equipment and easy operation, and has attracted extensive attention. It is currently one of the most important methods for preparing continuous polymer nanofibers. one. With the continuous development of nanomaterial technology, electrospinning, as a simple and effective new processing technology for producing nanofibers, plays a huge role in biomedical materials, filtration and protection, catalysis, energy, optoelectronics and food engineering. Electrospinning technology is simple and efficient, and researchers have made a lot of innovations in equipment, but most...
