An opening and closing induction batch electrospinning device

Abstract

The invention discloses an opening-closing induction type batch electro-spinning device and relates to an electrostatic spinning device. A material storage box is communicated with a liquid supply device. A heating piece and a temperature sensor are arranged on an inner cavity wall of the material storage box. The heating piece and the temperature sensor are electrically connected with a temperature control box. A nozzle array is arranged at the bottom of the material storage box. Center shafts are arranged in nozzles. The center shafts penetrate through the material storage box vertically. The lower ends of the center shafts are connected with nozzle covers which are placed outside nozzle outlets. The upper ends of the center shafts extend out of the upper end face of the material storage box. A driving motor and a multi-shaft output box are arranged above the material storage box. The driving motor is arranged on the multi-shaft output box. An output shaft of the driving motor is connected with the input end of the multi-shaft output box. The output ends of the multi-shaft output box are connected with the upper ends of the center shafts. A vibration output end of a vibration generator is in rigid connection with the multi-shaft output box. Conducting metal strips are arranged on the bottom face in the material storage box at intervals horizontally and longitudinally. The conducting metal strips are connected to the ground or are electrically connected with a high-voltage power supply. A collecting device is placed below the material storage box. The collecting device is electrically connected with the high-voltage power supply or is connected to the ground.

Description

technical field [0001] The invention relates to an electrospinning device, in particular to an opening and closing inductive batch electrospinning device. Background technique [0002] Polymer droplets in a strong electrostatic field will overcome their own surface stress and generate a jet from the tip of the Taylor cone. The jet will be continuously refined and reach the micro-nano level under the effects of electrostatic field force, viscous resistance, surface tension, etc., and spray to the collection device , and finally obtain nanofibers, this method of preparing nanofibers is called electrospinning. Electrospinning technology has been widely used to prepare various polymer nanofibers due to its simple process and low equipment requirements. [0003] Realizing the batch production of nanofibers based on electrospinning technology has always been the research focus of scientific researchers, such as the published Chinese patents CN102383204A, CN103173873A, etc. The l...
