The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
请参见图1，本发明的一较佳实施例的恒定持续供液装置100用于各种静电纺丝装置中，包括至少两组供液组件(未标号)、分别与每组供液组件连接的供液容器5及对应供液组件的数量设置的至少两个导液管4。Referring to FIG. 1, a constant continuous liquid supply device 100 according to a preferred embodiment of the present invention is used in various electrospinning devices, including at least two sets of liquid supply components (not labeled), respectively connected to each set of liquid supply components. The liquid supply container 5 and the at least two liquid guiding tubes 4 provided corresponding to the number of the liquid supply components.

The hydraulic cylinder 1 is vertically connected in parallel through the liquid guiding tube 4 and its flow curve is coupled and set. The cylinder 1 has a cylinder 11 and a plunger 12 disposed on the cylinder 11. The cylinder 11 is divided into two sub-cavities 13 by a plunger 12, and at least one of the sub-chambers 13 is filled with a spinning solution. The driving plunger 12 reciprocates linearly, and the sub-cavity 13 filled with the spinning solution communicates with the liquid supply container 5 and the liquid guiding tube 4. Each of the liquid guiding tubes 4 is mounted with a first one-way valve 61, and each of the sub-cavities and the liquid supply container 5 is connected by a conduit 4, and each of the conduits 4 is mounted with a second one-way valve 6, the first one-way The guiding of the valve 61 is opposite to the guiding of the second one-way valve 6.
驱动装置包括动力部件3及连接动力部件3和柱塞12的传动部件2。动力部件3为伺服电机。传动部件2为丝杠组件。丝杠组件2包括与伺服电机3连接的联轴器(未图示)、与联轴器连接的丝杠2及设置在丝杠2上的夹持块21，夹持块21与柱塞12的端部连接，丝杠2转动带动柱塞12做往复直线运动。The drive unit includes a power unit 3 and a transmission unit 2 that connects the power unit 3 and the plunger 12. The power unit 3 is a servo motor. The transmission member 2 is a screw assembly. The lead screw assembly 2 includes a coupling (not shown) connected to the servo motor 3, a lead screw 2 connected to the coupling, and a clamping block 21 disposed on the lead screw 2, the clamping block 21 and the plunger 12 The end of the connection, the screw 2 rotates to drive the plunger 12 to make a reciprocating linear motion.
在本实施例中，供液组件为两组，即该恒动持续供液装置100设置有两个伺服电机3、两个液压缸1及两个丝杠组件2。In the present embodiment, the liquid supply components are two groups, that is, the constant-current continuous liquid supply device 100 is provided with two servo motors 3, two hydraulic cylinders 1, and two screw assemblies 2.

The solution, the two hydraulic cylinders 1 have the same speed of movement and complement each other.
再结合图2，本发明还提供了一种恒定持续供液方法，所述工作方法包括如
下步骤：给两个伺服电机3设定一致的参数，设定液压缸1的流量曲线并使两个液压缸1的流量曲线耦合。单独一个液压缸1的输出流量为q＝|v|*A，两个液压缸1上下并联设置，则两个液压缸1的输出流量为q＝|v1|*A1+|v2|*A2＝(|v1|+|v2|)*A。又因为已设定两个液压缸1的输出流量曲线耦合，则上下两个液压缸1的柱塞12的运动速度为|v1|+|v2|＝C，C为常数。2, the present invention also provides a constant continuous liquid supply method, the working method comprising the steps of: setting a uniform parameter to two servo motors 3, setting a flow curve of the hydraulic cylinder 1 and making two The flow curve of the hydraulic cylinder 1 is coupled. The output flow rate of a single hydraulic cylinder 1 is q=|v|*A, and the two hydraulic cylinders 1 are arranged in parallel in parallel, the output flow rate of the two hydraulic cylinders 1 is q=|v 1 |*A 1 +|v 2 | *A 2 =(|v 1 |+|v 2 |)*A. Further, since the output flow rate curves of the two hydraulic cylinders 1 have been set, the moving speed of the plunger 12 of the upper and lower hydraulic cylinders 1 is |v 1 |+|v 2 |=C, and C is a constant.
即当其中一个液压缸(即液压缸一)向静电纺丝装置输送纺丝溶液时，另一个液压缸(即液压缸二)则从供液容器5中汲取纺丝溶液，两个液压缸1的运动速度一致且动作互逆，实现互补。最后启动装置。That is, when one of the hydraulic cylinders (ie, the hydraulic cylinder 1) conveys the spinning solution to the electrospinning device, the other hydraulic cylinder (ie, the hydraulic cylinder 2) draws the spinning solution from the liquid supply container 5, and the two hydraulic cylinders 1 The movement speed is consistent and the movements are reciprocal, complementing each other. Finally start the device.

The electrospinning device is a coaxial electrospinning device provided with two constant continuous liquid supply devices 100 of the present invention, and a constant continuous liquid supply device 100 is connected to the inner casing of the spinning nozzle 7 through a liquid guiding tube 41. Another constant continuous liquid supply device 100 is connected to the outer casing of the spinneret 7 through the liquid conduit 42, and the two constant continuous liquid supply devices 100 simultaneously supply liquid, and the plunger 12 of the hydraulic cylinder 1 in the constant liquid supply device 100 is constantly maintained. The speed of movement remains the same. The spinning nozzle 7 is driven by the high-voltage power supply device 9 to spray the spinning solution onto the corresponding receiving device aluminum foil 8 for receiving, thereby realizing a large number of preparations for producing micro-nano materials.

In the middle, the page in the liquid supply tank 5 is kept unchanged.
