Composite melt-blown cloth production device and production method of composite melt-blown cloth

Abstract

The invention discloses a coating device, which is provided with a notch and a placement groove on the coating platform; among adjacent widened plates, the second long open slot in the widened plate positioned inside and the second long open slot of the widened plate positioned outside The two strip projections slide and cooperate with each other, and the pushing protrusion of the widened plate on the outside stretches into the strip guide groove in the widened plate on the inside and contacts with the front inner wall of the strip guide groove; the position on the outside The widened plate can move forward and drive all the widened plates inside it to move forward synchronously; the cover plate can be covered on the placement groove, and the top surface of the cover plate is flush with the top surface of the coating platform. The invention also discloses a production device for composite melt-blown cloth and a production method for composite melt-blown cloth. The invention has the advantages of being able to change the coating width in real time to meet the requirements of cloth coating with different widths, reducing the residue of the coating material on the coating platform, improving the function of the cloth and increasing the production efficiency.

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
