WIPO Patent Application WO/2024/036769
Kind Code:
A1
Abstract:
The present invention provides a continuous synchronous pressing mechanism for the inner wall of a drum body. The mechanism applies continuous pressure to a thin film after the thin film is attached to the inner wall, so as to ensure that the thin film is completely attached to the inner wall. The mechanism comprises: a runway-shaped track conveyor belt that comprises an upper straight section, a lower straight section, and two arc-shaped connecting ends; a continuous conveyor belt; and a plurality of prepressing and following press-attachment head assemblies, each prepressing and following press-attachment head assembly comprising a press-attachment head mounting frame, a cam assembly, and press-attachment heads on both sides, wherein mounting seats for the press-attachment heads are respectively embedded in two sides of the horizontal plane of the press-attachment head mounting frame by means of guide rails, a compression spring is also provided between each mounting seat and the press-attachment head mounting frame, the compression spring causes the side part of a press-attachment head not in a working state to inwardly retract at the corresponding side end of the press-attachment head mounting frame, the cam assembly is arranged in a middle region between the two opposite mounting seats, and when a large diameter end of a cam is inserted in the region between the two mounting seats, the press-attachment heads on both sides laterally protrude from the corresponding side ends of the press-attachment head mounting frame.
