Description

Technical Field

[0001] The utility model relates to the technical field related to meltblown cloth processing, and specifically to a winding device for an under-net suction type meltblown cloth production line. Background Art

[0002] Meltblown cloth is mainly made of polypropylene as the main raw material. The fiber diameter can reach 1 to 5 microns, with many gaps, fluffy structure and good wrinkle resistance. These ultrafine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the meltblown cloth has good filtering, shielding, insulation and oil absorption properties; the raw material is sprayed with hot air, and hot polypropylene is squeezed out from the fine holes of the nozzle of the spinneret to make it extend in fiber shape, and then gathered on the conveyor belt to form a fiber web according to its self-welding property. Many nozzles with a diameter of 0.15 mm are arranged on the spinneret. The molten polypropylene flow ejected from the nozzle is extended by high-speed air flow and concentrated on the moving conveyor belt to obtain meltblown cloth. When rolling up the meltblown cloth, it is necessary to absorb the meltblown cloth flatly on the mesh curtain by suction under the mesh curtain to facilitate the rolling, transportation and storage between each process.

[0003] The existing patent (publication number: CN 217756066U) discloses a winding device for an under-net suction type meltblown cloth production line, which blows the surface of the meltblown cloth by rotating the fan blades. At the same time, the suction nozzle absorbs the dust into the dust collecting box, thereby improving the safety of hygiene; the meltblown cloth passing through the surface of the mesh curtain is adsorbed by the negative pressure suction cup, and it is stretched during the winding process to ensure that the surface of the meltblown cloth will not produce ripples and wrinkles, thereby improving the quality of the meltblown cloth.

[0004] However, the above technical solution still has certain defects. The winding device of the under-net suction type meltblown fabric production line collects the dust on the surface of the meltblown fabric through a suction nozzle. Since the suction force of the suction nozzle is small and it is only arranged at the top of the fabric, its dust absorption capacity for the surface of the meltblown fabric is poor. Dust will still remain after processing, thereby reducing the processing efficiency. Therefore, a winding device for an under-net suction type meltblown fabric production line is proposed.
