An adjustable cutting device for melt-blown cloth

Abstract

The invention provides an adjustable cutting device for melt-blown cloth, which belongs to the technical field of melt-blown cloth processing equipment. It includes a cutting frame, a melt-blown cloth unwinding device, a melt-blown cloth guide tensioning device, an adjustable cutting device, a melt-blown cloth winding device, a side material winding device, and a melt-blown cloth unwinding device including a melt-blown cloth Cloth unwinding mechanism and melt blown cloth unwinding damping mechanism, melt blown cloth guiding and tensioning device includes guiding mechanism and tensioning mechanism, melt blown cloth rewinding device includes melt blown cloth rewinding mechanism, melt blown cloth rewinding and pasting mechanism . The invention can not only realize the cutting and winding of the melt-blown cloth smoothly, but also has adjustable cutting width, good width adjustment accuracy, and good winding stability and stability.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth processing equipment, in particular to an adjustable cutting device for melt-blown cloth. Background technique [0002] Melt blown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1-5 microns. There are many voids, fluffy structure, and good wrinkle resistance. The ultrafine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt blown cloth has good filterability, shielding, heat insulation and oil absorption. It can be used in air and liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials, oil absorption materials and wiping cloths and other fields. It is mainly used in the following fields: (1) medical and sanitary cloth: surgical gowns, protective clothing, disinfection wraps, masks, diapers, women's sanitary napkins, etc....

AI Technical Summary

Problems solved by technology

At present, the adjustment of the cutting width of the melt-blown cloth cutting equipment is very troublesome, and it is generally realized by manually adjusting the position of the cutting knife. Not only the adjustment efficiency is low, but also the position accuracy is poor.

Moreover, the rewinding paper cores of different specifications are generally set on the inflatable shaft to complete the rewinding, but because the change of the cutting width will lead to the change of the cutting position, the requirements for the installation position of the rewinding paper core are very high. At present, the winding paper core is generally manually installed on the inflatable shaft, and the accuracy of the installation position is poor. During the winding process, it will cause the smoothness of the cut melt-blown cloth, and even affect the continuity of the winding.
