Spinning apparatus with circular extruding function

Abstract

The invention discloses a spinning apparatus with a circular extruding function and belongs to the technical field of electrostatic spinning. The spinning apparatus comprises a mounting box; an injection pipe is fixedly communicated with the top center of the mounting box; the bottom of the mounting box is fixedly communicated with a plurality of needles; the top of the mounting box is fixedly connected with cleaning mechanisms corresponding to the needles; the cleaning mechanisms comprises an ejector pin coaxial to the needles, a fixing box and a linear driving device, the fixing boxes are fixedly connected with the top of the mounting box, the linear driving devices comprise a fixed end and a moving end, the fixed ends of the linear driving devices are fixedly connected with the tops ofthe fixing boxes, the ejector pins are positioned in the fixing boxes, the tops of the ejector pins are fixedly connected with the moving ends of the linear driving devices, and the bottoms of the ejector pins are extended into the mounting box. The spinning apparatus has the advantages that the blocked needles can be automatically cleaned; stopping the apparatus during cleaning is not required, so that labor intensity is reduced for workers and production efficiency is improved.

Description

technical field [0001] The invention relates to a spinning device with an annular spinning function, which belongs to the technical field of electrostatic spinning. Background technique [0002] Electrospinning is a special fiber manufacturing process. The polymer solution or melt is jet-spun in a strong electric field. The spinning device is mainly composed of a propulsion pump, a syringe, a high-voltage power supply and a receiving device. Under the action of an electric field, the droplet at the needle overcomes the surface tension, changes from a spherical shape to a conical shape (that is, "Taylor cone"), and extends from the tip of the cone to form a fiber filament. [0003] Such as figure 1 As shown, in the process of spinning, the solvent at the needle 1 is easy to volatilize, which will cause the high molecular polymer 2 to condense at the needle 1, and finally cause the needle 1 to be blocked. In the prior art, once the needle 1 is blocked, The whole equipment mu...
