An inner-hung membrane rotary shaft type membrane stretching structure for hollow glass

Abstract

The utility model relates to hollow glass technical field, specifically disclose a kind of inner suspension film spin shaft type film stretching structure for hollow glass, and the middle part of frame section is equipped with cylindrical cavity and inside wall is equipped with strip seam one along its axial direction;Four corner parts connectors are sequentially connected with four frame sections to form rectangular frame structure, and the inside of the side wall of cylindrical cavity is equipped with round groove in corner part connector, and the outside wall of corner part connector is equipped with square groove in the position of middle part of round groove;Spin shaft mechanism includes reel rotatably sleeved in cylindrical cavity and rotating member connected in reel two ends by axial elastic telescopic mechanism, and rotating member includes cylindrical one and the square block matched with square groove in the middle part of cylindrical one outer end surface;The periphery of inner suspension film is equipped with extension respectively, and the outer end of extension is wound on reel through corresponding strip seam respectively. The problem that the film stretching structure is difficult to guarantee the flatness of inner suspension film and is inconvenient to install is better solved.
