Continuous suspension type 3D coating equipment for producing nanofiber membrane

Abstract

The invention discloses continuous suspension type 3D coating equipment for producing a nanofiber membrane. The continuous suspension type 3D coating equipment comprises a main box body, wherein a storage box is arranged above the main box body, a limiting bottom frame is arranged below the main box body, a first motor is arranged on one side of the main box body, the output end of the first motor is fixedly connected with a threaded rod, a threaded rod is in threaded connection with a sliding top plate, a liquid supply device is arranged below the sliding top plate, a spinning nozzle and a protective cover are arranged below the liquid supply device, and a conveying belt is arranged on the lower portion in the main box body. According to the continuous suspension type 3D coating equipment, through the arrangement of the threaded rod, when the first motor is started, the threaded rod can be driven to rotate, so that the sliding top plate at the top of the liquid supply device can slide outside the main box body, then the spinning nozzle at the bottom of the liquid supply device is driven to be located above the conveying belt for uniformly coating, and the thickness of the fiber membrane can be adjusted by repeated coating of the spinning nozzle in a moving process.

Description

technical field [0001] The invention belongs to the technical field of fiber film production, and in particular relates to a continuous suspension 3D coating device for producing nanofiber films. Background technique [0002] Nanofibers refer to ultrafine fibers with a fiber diameter of less than 1000 nanometers. Nowadays, many companies refer to fibers filled with nano-scale (ie less than 100 nm) powder fillers as nanofibers for the promotion of products. There are many methods for fabricating nanofibers, such as stretching method, template synthesis, self-assembly, microphase separation, electrospinning, etc. Among them, the electrospinning method is widely used for its advantages of simple operation, wide application range, and relatively high production efficiency. Nanofibers have a wide range of uses. Form an amphiphobic interface fabric, which can not only waterproof, but also oil-proof and anti-fouling; the advanced protective clothing made of nanofibers, the fabric...

Problems solved by technology

[0004] The technical problem to be solved in the present invention is to overcome the existing defects, and provide a continuous suspension 3D coating equipment for producing nanofiber membranes, so as to solve the problems in the production and coating process of nanofibers proposed in the above-mentioned background technology. Single, it is difficult to carry out continuous and repeated coating, so it is difficult to adjust the thickness of the produced fiber film, and it is easy to spray the liquid fiber on the surrounding equipment and the air during the spraying process. Potential safety hazards and inconvenient cleaning, and the fiber is thin after forming, and it is easy to produce wrinkles during collection, which will affect the use of the problem
