Document Type and Number:
WIPO Patent Application WO/2021/253571
Kind Code:
A1
Abstract:
A fiber collector (7) for a melt-blown cloth production line, comprising a grid conveyor belt device (701); an open air extraction box (702) is provided inside the grid conveyor belt device (701), and the air extraction box (702) is connected to an air extraction fan (703) by means of a pipeline; a winding device (9) is correspondingly provided on a side portion of the fiber collector (7); and an air-balancing component is provided inside the air extraction box (702). By providing the air-balancing component having a specific structure in the air extraction box (702) of the fiber collector (7), air flows over the air extraction box (702) during production are uniform, and the amount of fibers received by different regions of the grid conveyor belt device (701) is consistent, so that a melt-blown cloth product produced has a uniform thickness and good quality.
