Electrospinning device with automatic control of lifting and discrete collection device

Abstract

The invention discloses a split type electrospun fiber collecting device capable of lifting under automatic control and belongs to the field of electrospinning, aiming to solve the problem of unreasonable space occupation of equipment due to the fact that conventional electrospun fiber sample collecting devices are integrated with spinning devices or correspond to the same only. The split type electrospun fiber collecting device comprises a hollow rectangular box, a holder and a lifting table; the lifting table is mounted under the box in a detachable way; along with lifting of the lifting table, the box lifts until an electrospun fiber spinning needle is inserted into hole of a rubber gasket.

Description

technical field [0001] The invention belongs to the field of electrospinning and relates to a device for collecting electrospun fiber samples in a constant humidity and constant temperature environment. Background technique [0002] Electrospinning technology is widely used in the field of nanofiber material preparation. Due to its excellent physical and chemical properties, nanofiber materials have a wide range of application fields and unlimited development prospects. Countries are stepping up to improve the existing electrospinning technology or develop new electrospinning equipment. In the process of electrospinning, the charged polymer solution is sprayed, stretched, split, volatilized and solidified in a high-voltage electrostatic field to finally form fibrous properties. There are many parameters that affect the morphology and properties of electrospun fibers, such as the voltage provided by the high-voltage power supply, the distance between the collecting plate and...

Problems solved by technology

[0003] In order to solve the problem of unreasonable space occupied by the existing electrospinning fiber sample collection device and the injection device caused by the integrated or unique correspondence, the present invention proposes the following solution: an electrospinning fiber collection device with a separate collection device that can automatically control the lifting The device includes a hollow rectangular box, a pallet, and a lifting platform. An air intake valve is arranged on the box, and an exhaust valve is correspondingly provided. The air intake valve is connected to a constant humidity and temperature air source machine to supply air Air supply inside the box, the top surface of the box has a rubber pad, the rubber pad has a pinhole for inserting the electrospun fiber jet needle into the box, and a metal slideway is set on the bottom surface of the box, and the support is a cylindrical metal body, The bottom of the box has a chute that matches the metal slideway on the bottom of the box so that it can be slidably connected to the metal slideway; the electrode jack on the box is connected to the metal slideway, and the electrode jack is connected to the metal slideway through the power cord. The negative pole of the high-voltage power supply, the injection needle of the electrospun fiber is connected to the positive pole of the high-voltage power supply, and the lifting table can be installed separately under the box, and its rise makes the box rise with it, so that the injection needle of the electrospun fiber is inserted into the pinhole of the rubber pad
