Description

technical field [0001] The invention belongs to the field of melt-blown cloth production equipment, and in particular relates to a conveying and absorbing device for melt-blown cloth production, which is mainly used in 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 fibers Bonding opportunities, the diameter of polypropylene ultrafine fibers can reach 1-5 microns, and the ultrafine fibers with a unique capillary structure increase the number and surface area of ​​fibers per unit area, with many voids, fluffy structure and good wrinkle resistance, making melt blown cloth The filter material has a larger specific surface area and higher porosity, so that th...

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 meltblown cloth once, and it is difficult to use the miscellaneous air duct to continuously and reciprocally absorb the adhesive fibers on the surface of the meltblown cloth, resulting in sticky fibers on the surface of the meltblown cloth. The absorption efficiency of the attached fibers is low and the quality is poor. In order to improve the absorption efficiency of the adhered fibers on the surface of the melt-blown cloth, it is necessary to bring the miscellaneous air duct and the surface of the melt-blown cloth as close as possible, and at the same time increase the air volume of the miscellaneous air duct, but in When the above method is used to absorb 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, so that the melt blown cloth will be broken due to the suction of the miscellaneous suction duct. Adsorption fits the suction inlet of the suction duct, causing 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 transmission and processing of the melt blown cloth, and reduce the The quality of the production and processing of meltblown cloth is difficult to meet the needs of production and use
