[0020] like Figure 1-Figure 2 As shown, this embodiment provides an automatic cloth dropping device for automobile interior non-woven fabrics, including two connecting plates 1, two L-shaped swing plates 2, two synchronous pushing cylinders 7, two first swing plates 3, a roller body 4 and a limit assembly 5.

[0021] The two connecting plates 1 are arranged at intervals, and the connecting plates 1 are provided with a first through hole. The connecting plates 1 are provided with two guide holes and a first threaded hole, and the two guide holes are located above and below the first threaded hole.

[0022] The same set of first swing plates 3 and L-shaped swing plates 2 are respectively located on both sides of any connecting plate 1, the L-shaped swing plate 2 is located on the outward side of the connecting plate 1, the roller body 4 is rotatably connected between the two first swing plates 3, and the roller body 4 is located at the lower end of the surface of the first swing plate 3. The L-shaped swing plate 2 has a long section and a short section, and the end of the long section and the upper end of the surface of the first swing plate 3 are fixedly connected by a synchronous rotation rod 6, the synchronous rotation rod 6 passes through the first through hole, and the L-shaped swing plate 2 and the first swing plate 3 swing around the axis of the synchronous rotation rod 6.

[0023] The output end of the synchronous push cylinder 7 is rotationally connected to the outer surface of the short section. In this scheme, the synchronous push cylinder 7 is an oil cylinder. The synchronous push cylinder 7 swings as the output end is ejected and retracted. The L-shaped swing plate 2 and the first swing plate 3 swing around the axis of the synchronous rotation rod 6. Specifically, the synchronous push cylinder 7 includes an ejection column and a cylinder body. The end of the ejection column is hinged to the surface of the short section. An extension plate is formed on the lower surface of the rear end of the cylinder body. The extension plate has a second through hole. When the cylinder body is fixed on the frame, an articulated seat is formed on the frame, and the extension plate extends into the articulated seat. A rotating shaft is provided in the articulated seat, and the rotating shaft passes through the second through hole, thereby ensuring that the cylinder body can swing when the ejection column is ejected or retracted.

[0024] The limit assembly 5 is used to limit the swing position of the first swing plate 3. Specifically, the limit assembly 5 includes two limit bars 53, the two limit bars 53 are located on the sides facing each other of the two first swing plates 3, the surface of the limit bar 53 has two guide pillars 51 and a screw rod 52, one end of the screw rod 52 is rotatably connected to the limit bar 53, specifically, the side of the screw rod 52 facing the limit bar 53 forms a limit cone, the diameter of the limit cone is greater than the diameter of the screw rod 52, the surface of the limit bar 53 forms a limit seat, the limit seat has a limit rotation hole, the limit rotation hole includes a stop portion and an insertion portion, the stop portion is adapted to the limit cone, the diameter of the insertion portion is greater than or equal to the diameter of the screw rod 52, and the diameter of the insertion portion is smaller than the diameter of the stop portion. The screw rod 52 passes through the first threaded hole and is adapted thereto, a handwheel is provided at the other end of the screw rod 52, and the guide column 51 passes through the guide hole and is adapted thereto. Specifically, a stabilizing ring 11 is formed around the opening of the outward side of the guide hole. Since the connecting plate 1 is too thin, the guide column 51 may shake when it is displaced in the guide hole, so a stabilizing ring 11 is provided for limiting the position, so that the guide column 51 can be more stable during the movement.

[0025] Working principle: During normal working, the output end of the synchronous push cylinder 7 is in an extended state. When cloth dropping is required, the output end of the synchronous push cylinder 7 is retracted, and the L-shaped swing plate 2 swings downward with the axis of the synchronous rotating rod 6 as the rotation axis. Under the action of the synchronous rotating rod 6, the first swing plate 3 also swings downward following the L-shaped swing plate 2 to realize automatic cloth dropping.
