Abstract

The invention discloses a melt-blown cloth conveying and processing device, and belongs to the field of melt-blown cloth production equipment. The melt-blown cloth conveying and processing device is characterized in that a cloth feeding and guiding mechanism, a cloth pressing and impurity sucking mechanism and a cloth pulling and conveying mechanism are sequentially arranged on a cloth conveying and processing support; a melt-blown cloth pressing rotary roller is arranged on the upper side of a cloth feeding and conveying rotary roller, a front positioning cloth pressing plate is arranged on the upper side of a front lifting guide plate, and a rear positioning cloth pressing plate is arranged on the upper side of a rear lifting guide plate; a reciprocating and impurity sucking mechanism isarranged on the part, on the upper sides of the front positioning cloth pressing plate and the rear positioning cloth pressing plate, of the cloth conveying and processing support; and a front clothpulling guide plate and a rear cloth pulling guide plate are arranged on the two sides of a reciprocating cloth pulling guide rod, and a disc positioning mechanism is arranged on the part, on the lower side of a cloth pulling rotating disc, of the cloth conveying and processing support in the radial direction of the cloth pulling rotating disc. The melt-blown cloth conveying and processing deviceis reasonable in structural design, melt-blown cloth can be efficiently, conveniently and sequentially pulled and conveyed in a segmented mode, the melt-blown cloth can be stably and smoothly subjected to segmented impurity sucking processing in the melt-blown cloth conveying process, the automation degree of melt-blown cloth production and processing is improved, and the requirements of production and use are met.

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 ...
