A device for making double-sided embroidery by double-sided electrospinning

Abstract

The invention discloses a device for preparing double-sided embroidery through double-sided electrostatic spinning. The device mainly comprises a base plate, receiving cloth, spraying heads, a high-pressure power supply, calibration optocouplers, a transmission device and a control circuit, wherein the receiving cloth is located on the middle surface between two symmetric spraying heads; the two symmetric spraying heads are in fixed states relative to up-down direction, and left-right direction of the board surface of the receiving cloth, and can only move along the normal direction of the board surface of the receiving cloth; the receiving cloth can move in parallel in the surface direction of the receiving cloth; the control circuit controls the transmission device to move according to a pattern of the double-sided embroidery by calculating a path of an electrostatic spinning Taylor's cone, so as to drive the receiving cloth and the two spraying heads to move; the receiving cloth and spraying head nozzles are respectively connected to the positive and negative electrodes of a high-pressure power supply, and the control circuit is used for controlling on and off of the high-pressure power supply. Compared with a conventional double-sided embroidery preparation device, the device for preparing the double-sided embroidery through the double-sided electrostatic spinning has the advantages that by the use of the symmetric two-spraying-head electrostatic spinning device, the efficiency and the operability are greatly improved, and the exquisiteness of the double-sided embroidery is also greatly improved.

Description

technical field [0001] The invention belongs to the fields of material science and aesthetics. Specifically, the electrospinning method is used to prepare double-sided embroidery on a certain board surface. Background technique [0002] With the development of nanotechnology, electrospinning is a simple and efficient new processing technology for preparing ultrafine fibers. Its spinning products can be used in biomedicine, filtration and protection, catalysis, energy, photoelectric food engineering, aerospace materials and other fields, play a huge role. [0003] In the process of electrospinning, a certain voltage is applied to the nozzle (anode), and an electrostatic field is formed between the nozzle and the receiving surface, and a large amount of charge is enriched on the surface of small droplets or melt droplets in the electric field. When the charge repulsion on the surface of the droplet is greater than or equal to its surface tension, a tiny "jet" is generated on...
