Description

Technical field [0001] The invention belongs to the field of melt-blown cloth production equipment, and particularly relates to a melt-blown cloth transmission and processing device, which is mainly applied to the continuous production and processing of melt-blown cloth. Background technique [0002] Melt blown cloth is the core material of the mask. The melt blown cloth filter material is randomly distributed and bonded together by polypropylene microfibers. The appearance is white, flat and soft. The random distribution of polypropylene microfibers provides more heat between the fibers. For bonding opportunities, the diameter of polypropylene microfibers can reach 1 to 5 microns, and the microfibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, with many voids, fluffy structure and good wrinkle resistance, making meltblown fabrics The filter material has a larger specific surface area and higher porosity, so that the meltblown c...

Problems solved by technology

During the production process of melt-blown cloth, the high-speed hot air flow is used to draw the polymer melt stream extruded from the spinneret hole of the die head, thereby forming ultra-fine fibers and collecting them on the condensation net curtain or roller, and at the same time Bonded to become a melt-blown nonwoven fabric. The ultra-fine fibers formed by the polymer melt can be collected into a mesh cloth structure by using the web forming equipment. Roll and other processing procedures, during the process of melt-blown cloth being melt-blown into a web and cooled and shaped by using a web-forming equipment, some of the ultra-fine fibers drawn from the polymer melt will be difficult to be effectively collected due to factors such as breakage. A firm network structure is formed, so that the surface of the melt-blown cloth conveyed by the web-forming equipment will be adhered to the fluffy fiber material, so it is necessary to separate the adhered fibers before the melt-blown cloth is slitting and winding. Material removal can ensure the quality of the melt-blown cloth in the subsequent winding process. The existing method for removing the adhered fiber material on the surface of the melt-blown cloth is mainly used in the process of conveying the melt-blown cloth, using the miscellaneous air blown that is arranged in close proximity. The pipe absorbs the fiber material adhered to the surface of the melt-blown cloth, and the miscellaneous air pipe is connected with the external blower. side, the miscellaneous air duct can only absorb the adhesive fibers on the surface of the melt blown cloth once, and it is difficult to use the miscellaneous air duct to continuously reciprocate the adhesive fibers on the surface of the melt blown cloth for multiple times, resulting in The absorption efficiency of the adhesive fibers on the surface of the spray cloth is low and the quality is poor. In order to improve the absorption efficiency of the adhesive fibers on the surface of the melt-blown cloth, it is necessary to make the miscellaneous suction duct as close as possible to the surface of the melt-blown cloth, and at the same time improve the suction efficiency of the miscellaneous duct. However, when the above method is used to absorb the fibers, the melt blown cloth during the transmission process will not be compressed and fixed on both sides of the melt blown cloth, and the texture of the melt blown cloth is relatively light and thin, so that the melt blown cloth will be blown due to the miscellaneous wind The suction of the pipe is adsorbed and attached to the suction inlet of the suction duct, which causes the melt blown cloth to be pulled and twisted under the adsorption of the suction duct, making it difficult to ensure the normal and orderly delivery of the melt blown cloth processing, and reduces the quality of melt-blown cloth production and processing, it is difficult to meet the needs of production and use
