Melt blown cloth conveying mechanism

Abstract

The invention discloses a melt blown cloth conveying mechanism, and belongs to the field of melt blown cloth production equipment. Two sides of the upper part of a cloth transfer processing support are horizontally and rotatably connected with cloth transfer guide rollers separately, a cloth pulling transfer mechanism is horizontally arranged on the cloth transfer processing support between the two cloth transfer guide rollers, and a disc positioning mechanism is arranged on the cloth transfer processing support on the lower side of the cloth pulling transfer mechanism. A front cloth pulling guide plate and a rear cloth puling guide plate are horizontally and slidably arranged on two sides of a reciprocating cloth pulling guide rod separately, and a reciprocating cloth pulling chain wheelis horizontally connected to a reciprocating cloth pulling chain in a winding mode. A reciprocating pulling connecting rod is arranged between tooth plate translation connecting rods on one sides of acloth pulling rotation disc and a reciprocating translation tooth plate, and the disc positioning mechanism is arranged on the cloth transfer processing support under the cloth pulling rotation discin the radial direction of the cloth pulling rotation disc. The structure of the melt blown cloth conveying mechanism is reasonable in design, melt blown cloth can be efficiently and smoothly and intermittently stretched and conveyed in sections, the automation degree of the melt blown cloth conveying is improved, and needs of production and use are met.

Description

technical field [0001] The invention belongs to the field of melt-blown cloth production equipment, and in particular relates to a melt-blown cloth conveying mechanism, which is mainly used in 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 the melt-blown cloth has good fi...

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 for subsequent winding processing. In order to achieve efficient and convenient absorption of the adhered fibers on the surface of the melt-blown cloth, it is necessary to process the melt-blown cloth in sections to absorb impurities. In order to meet the requirements of the melt-blown Cloth segmented and efficient absorbing processing requires that the melt-blown cloth be conveyed sequentially in segments, and it is necessary to pause for the required time during the segmental transmission of the melt-blown cloth to realize the intermittent pulling and feeding of the melt-blown cloth, so that the melt-blown cloth Spray cloth can fully and efficiently carry out miscellaneous processing when the pulling transmission is stopped. The existing melt blown cloth transmission mechanism has complex structure and troublesome operation. It is difficult to achieve a uniform and orderly pause in the process, and it is impossible to ensure that the melt blown cloth stops at the same time every time, which affects the normal and orderly absorbing processing of the melt blown cloth, reduces the quality and efficiency of the production and processing of the melt blown cloth, and is difficult to meet the production requirements. needs
