Description

Technical Field

[0001] This utility model belongs to the field of electrospinning preparation technology, and specifically relates to a polymer electrospinning production equipment. Background Technology

[0002] Electrospinning is an advanced process that uses electrostatic force to stretch, refine, and ultimately solidify polymer solutions or melts into ultrafine fibers. Its core principle is to allow charged polymer solutions or melts to flow and deform in an electrostatic field, followed by solvent evaporation or melt cooling to solidify, thus obtaining fibrous materials. Fiber diameters can reach the micrometer, submicrometer, or nanometer scale. Nanofiber membranes made from absorbable polymer materials using this method are widely used in postoperative anti-adhesion applications due to their excellent biocompatibility and degradability. However, the high-quality nanofiber bundles prepared for anti-adhesion membranes using existing electrospinning equipment suffer from poor uniformity, making it difficult to achieve stable and efficient continuous injection and obtain a large-area uniformly deposited fiber bundle structure, thus affecting the membrane's physical properties and anti-adhesion effect. Utility Model Content

[0004] The technical solution of this utility model is as follows:

[0008] The injection system also includes an electrode plate, which is fixed to one end of a balance plate on the same side as the shunt. The electrode plate has multiple channels arranged parallel from top to bottom, and a metal needle is inserted into each channel. The metal needle is connected to the shunt tube.

[0009] A receiving system includes a receiving roller, which is a horizontally arranged cylindrical structure. Both ends of the receiving roller are fixed to the equipment base by a support frame. The receiving roller is connected to a second servo motor and can rotate at a constant speed to receive fiber bundles.

[0010] It also includes a high-voltage power supply, which is connected to the electrode plate and outputs high voltage to the electrode plate through a high-voltage wire.

[0011] Furthermore, the bottom of the feeding tank is lower than the peristaltic pump, so that the electrospinning solution in the feeding tank can be output to the peristaltic pump.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention relates to a polymer electrospinning device that can form a uniform fiber membrane.

It can form a temporary isolation layer on the surgical wound, preventing direct contact between adjacent tissues in the early healing stage. It has good biocompatibility and gradually degrades into harmless substances in the body, eliminating the need for secondary surgery to remove it. This significantly reduces the risk of postoperative adhesion. The polymer electrospinning device can efficiently and stably prepare highly uniform fiber membranes, and the operation process is simple. Attached Figure Description
