Embodiment Construction

[0031] The present invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this:

[0032] Such as figure 1 Shown: the main structure of the microfluidic injection pump system design includes a microfluidic syringe pump, a stepper motor driver (LV8729 driver board, LV8729 motor driver chip of Sanyo Semiconductor Corporation), a lower computer main control module (STM32 control board, Italian stm32f407 of French semiconductor company) and host computer (MCGS touch screen). The main body of the microfluidic syringe pump is designed as follows:

[0033] Such as figure 2 As shown: the micro-flow pump system uses a two-phase hybrid screw stepper motor 2 as the main core of the system, and the motor 2 must meet the requirements of low step angle, large torque and high precision; as a better embodiment , choose a Wheatstone 42 stepper motor as the motor 2 of the syringe pump system, the fixed step an...

Abstract

The invention discloses a micro-flow injection pump system for electrostatic spinning. The injection pump system comprises an injection pump, drive plates, a control panel and an upper computer, wherein the upper computer communicates with the control board mutually; the control board is separately connected to multiple micro-flow injection pumps through multiple drive plates; the core of the injection pump is a step motor which rotates to drive a slide table to move left and right; an injector is fixedly arranged on the slide table; the drive plate supports high-subdivision drive operation ofthe step motor; the control board receives the instruction of the upper computer through a 485 serial port, and controls the injection pump to act; the upper computer is a high-definition display screen which displays solution injection amount and solution injection progress in real time in addition to setting system operation parameter; and the micro-flow pump system supports one upper computerto simultaneously control multiple injection pumps. The micro-flow injection pump system is high in operation precision, is convenient in operation, and achieves injection speed range of 0.1 mL / h to 50 mL / h.

Description

technical field [0001] The invention relates to the design of a microfluid injection pump system for electrospinning, and relates to the technical fields of nanomaterial preparation and medical device manufacturing. Background technique [0002] In recent years, nanomaterials have been widely used in social production and life. Electrospinning technology is currently the most common method for preparing polymer nanofibers in the field of materials. The polymer solution is pushed out from a microflow pump with a capillary at a certain speed, and the capillary part is placed in a strong electric field. Under the action of a strong electric field, the polymer solution will form a Taylor cone at the top of the capillary; gradually increase the electric field strength until the polymer solution overcomes the surface tension and forms a jet stream; the jet stream moves irregularly and splits in the strong electric field into multi-strand filament fibers, and finally form nanofibe...
