Composite melt-blown fabric production device and composite melt-blown fabric production method

Abstract

The invention discloses a coating device. A notch and a placing groove are formed in a coating platform; in the adjacent widening plates, a second long-strip open groove in the widening plate locatedinside is in sliding fit with a second long-strip convex block of the widening plate located outside, and a pushing convex block of the widening plate located outside extends into the long-strip guidegroove in the widening plate located inside to be in contact with the front inner wall of the long-strip guide groove; the widening plate located outside can move forwards to drive all the widening plates on the inner side of the widening plate to move forwards synchronously; and a cover plate can cover the placing groove, and the top surface of the cover plate is flush with the top surface of the coating platform. The invention further discloses a composite melt-blown fabric production device and a composite melt-blown fabric production method. The composite melt-blown fabric production device and the composite melt-blown fabric production method have the advantages that the coating breadth can be changed in real time to meet coating of cloth with different breadths, residues of coatingmaterials on the coating platform are reduced, the cloth function is improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth, in particular to a production device for composite melt-blown cloth and a production method for composite melt-blown cloth. Background technique [0002] The melt-blown cloth uses high-speed hot air flow to draw the polymer melt stream extruded from the spinneret hole (discharge hole) of the die head, thereby forming ultra-fine fibers and collecting them on the condensing screen or roller, and at the same time Self-adhesive to become a melt-blown nonwoven fabric. [0003] With the development of society, people's demand for the performance of melt-blown cloth is no longer satisfied with the fiber material of melt-blown cloth itself, and various types of functionalized melt-blown cloth and preparation methods have emerged as the times require. [0004] The common functionalized or differentiated treatment of melt-blown cloth includes the method of lamination, and the lamination methods o...

AI Technical Summary

Problems solved by technology

The size (width) of the coating platform is usually fixed, so that when the cloth with a narrower width is knife-coated, since the width of the cloth is smaller than the width of the coating platform, the material liquid after scraping by the scraper will flow from The two sides of the scraper flow to both sides of the coating platform, and the coating liquid usually has a certain viscosity and curability. Therefore, the liquid flowing on both sides of the coating platform needs to be cleaned continuously, otherwise, the solidification On the coating platform, it will cause troublesome cleaning in the later stage and even affect the normal coating of the next piece of fabric

[0008] In addition, as the material feeding device of the main section of the coating process, since the feeding end of the feeding frame (unwinding frame) has a certain height, when feeding the fabric to the feeding frame, workers need to The fabric roll is lifted into the feeding station, and there is a technical problem of laborious operation

[0009] In summary, there is a need for improvement and further research in the process preparation and equipment optimization of the composite fabric production device in the prior art
