Embodiment 1

[0031] See Figure 1 to Figure 4 , a miniature continuous electrospinning forming device, the device includes a continuous liquid supply device, an electrostatic generator 25, and a spinneret 3 connected to two output ends of the electrostatic generator 25, and a collecting device 26, and the continuous liquid supply device The plunger pump 1 is connected to the liquid supply container 2 and the spinneret 3 through the connecting pipeline, and the reciprocating mechanism is connected to the plunger pump 1 and drives the plunger to reciprocate in the cylinder body. The plunger pump 1 and its connecting pipe There are two roads, and the two plunger pumps 1 are connected to the liquid supply container 2 and the spinneret 3 through their respective connecting pipelines; the plungers of the two plunger pumps 1 are connected to the reciprocating mechanism, And when one of the plunger pumps 1 is driven by the reciprocating movement mechanism to perform the suction movement, the other...

Embodiment 2

[0035] Such as Figure 5 As shown, the driving mechanism includes a cylinder 29 and a piston 30 matched therewith. When working, the pump body 32 outputs high-pressure liquid / gas to the reversing valve 31, and presses the high-pressure liquid / gas into the cavity on one side of the piston 30, the piston 30 moves, driving the plunger pump 1 to move, and the reversing valve 31 switches To the rear, the piston moves in the reverse direction, driving the plunger pump 1 to move in the reverse direction, so as to realize the reciprocating movement of the plunger pump 1 .

Embodiment 3

[0037] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that: the miniature continuous electrospinning forming equipment described in this embodiment has two liquid supply containers 2, two spinning nozzles 3; two plunger pumps 1 They are respectively connected to respective liquid supply containers 2 and spinnerets 3 through respective connecting pipelines. In this embodiment, the spinning dope in each liquid supply container 2 is different, so that each spinneret 3 can eject different dope respectively.

Abstract

The invention discloses a miniature continuous electrospinning forming equipment, which comprises a continuous liquid supply device, an electrostatic generator, a spinneret connected to two output ends of the electrostatic generator, and a collecting device, wherein the plunger pump passes through the connecting pipeline At the same time, it is connected with the liquid supply container and the spinneret. The reciprocating movement mechanism is connected with the plunger pump and drives the plunger to reciprocate in the cylinder. There are two plunger pumps and their connecting pipelines. The plunger pumps are respectively connected to the liquid supply container and the spinneret through their respective connecting pipelines; the plungers of the two plunger pumps are connected to the reciprocating mechanism, and one of the cylinders is driven by the reciprocating mechanism. When the plunger pump is doing the suction movement, the other plunger pump is doing the extrusion movement. Compared with the prior art, the present invention can continuously supply liquid to the spinneret to realize continuous sample preparation.

Description

technical field [0001] The patent of the invention belongs to the field of equipment preparation and material molding, including fiber materials, equipment prepared from woven and / or non-woven materials composed of fibers, and specifically relates to a micro-forming device that can realize continuous electrospinning. Background technique [0002] The unique properties and advantages of micron and nanofibers make them stand out among many fiber materials due to their small size effect. This type of fiber has a large specific surface area and unique mechanical properties, making it widely used in medicine, environmental protection, energy utilization, industrial construction and It has obvious application advantages in military defense and other aspects. [0003] The preparation methods of industrialized micro / nano fibers include composite spinning method, melt blown method, flash method and electrospinning technology that have appeared in recent years. Among them, the most s...
