[0003] At present, the tow stations in the filter rod forming workshops of various cigarette factories generally have the following problems: the tow station adopts anti-static transparent curtain cloth. Although the operator can observe the internal operation status of the equipment from all directions, the sealing effect of the curtain cloth is not good, which is not conducive to the dust removal of the upper negative pressure fan, absorbs the flying catkins of acetate fiber, and affects the working efficiency of the negative pressure fan. In addition, the curtain cloth is hung on the guide rail with hooks, and its own weight is heavy. It is easy to be damaged by repeated pulling and opening; the tow station built with aluminum profiles effectively solves the problems of sealing and durability, but the full manual operation cannot realize the automation of the opening and closing of the feed door; the rolling door solution realizes the automatic opening and closing of the sealed door, but the soft material roller shutter needs to rely on its own weight to achieve the smooth descent of the roller shutter when it falls, and there is a hidden danger of unsmooth descent, and the opaque material is not conducive to observing the internal working conditions. At the same time, the dust removal operation relies only on a single negative pressure fan, which makes the dust removal effect poor. Utility Model Content
