Background technique

Meltblown cloth is the core material of masks. Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, good wrinkle resistance, and the ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption. It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil absorbing materials and wiping cloths and other fields. Masks are generally composed of three layers, the outer non-woven fabric, the middle layer of melt-blown fabric, the outer layer of non-woven fabric, and the melt-blown fabric are the most important materials for mask production. Due to the large increase in the demand for masks due to the new coronary pneumonia in 2020, mask manufacturers have produced masks in large quantities to meet the market demand, so the demand for meltblown cloth has also increased.

The finished products of the meltblown cloth are all rolled, and the width of the rolled meltblown cloth is generally 160cm-180cm. Therefore, the rolled meltblown cloth needs to be slit before the meltblown cloth is processed into a mask. , so that the size of the meltblown cloth can meet the needs of mask production. Although the existing melt-blown cloth slitting machine can cut large rolls of melt-blown cloth into small rolls of melt-blown cloth, it cannot work with the mask production line, resulting in low production efficiency of the mask line; The spray cloth slitting machine cannot cut meltblown cloths of different widths, and the application range is small, and the size of the meltblown cloth cutting is not uniform, and at the same time, it will cause certain damage to the cutting edge of the meltblown cloth.
