The invention discloses an automatic non-woven fabric production line, which comprises a box body, a plurality of legs are evenly fixed on the lower surface of the box body, and a discharge port is opened on the lower right side of the box body. A discharge port is provided on the left side of the lower surface of the box, and the second opening and closing mechanism fits with the locking mechanism. The automatic non-woven fabric production line, through the cooperation of the second motor, the fourth gear, the wire and the second switch, realizes the control of the first opening and closing mechanism, so that the discharge port can be opened or closed, and the residual raw materials in the storage room are realized. Cleaning, through the cooperation of baffles, connecting plates, rivets, horizontal shafts, rotating sleeves, stops and pull rods, the locking of the second opening and closing mechanism is realized, so that the items in the storage room can be stored. Through the above structure, the It ensures the continuous supply of the raw material boxes of the automated non-woven production line, avoids the operation of stopping and loading materials, enables the automatic non-woven production line to produce uninterruptedly, and greatly improves the work efficiency.
