The invention discloses a film blowing machine capable of adjusting the tightness of a winding roller, and relates to the technical field of film blowing machines. Side fixing plates are fixedly arranged on the two sides of a lower bottom plate, rotating protruding blocks are fixedly arranged on the surfaces of the side fixing plates, and adjusting hydraulic cylinders are rotatably connected to the surfaces of the side fixing plates through the rotating protruding blocks; rotating lower protruding blocks are fixedly arranged on the rear side surfaces of fixing disc pieces, the fixing disc pieces are rotationally connected with the other ends of the adjusting hydraulic cylinders through the rotating lower protruding blocks, the peripheries of the fixing disc pieces are fixedly connected with one ends of springs, and the other ends of the springs are fixedly connected with surfaces of sliding fit blocks; main body supporting adjusting frames are fixedly arranged on the two sides of the surface of the lower bottom plate, inner adjusting grooves are formed in the four edges of the interiors of the main body supporting adjusting frames, and the sliding fit blocks are arranged in the inner adjusting grooves in a sliding mode; and the problems that the tightness of the winding roller cannot be easily and effectively adjusted, the adjusting range is limited, and the follow-up use rangeis affected are solved.
Description
technical field [0001] The invention relates to the technical field of film blowing machines, in particular to a film blowing machine capable of adjusting the tightness of winding rollers. Background technique [0002] The film blowing machine heats and melts plastic particles and then blows them into a film. It is mainly composed of an extruder, a die head, a cooling device, a bubble stabilizer, a herringbone plate, a traction roller, and a coiling device. [0003] There are certain defects in the use of traditional film blowing machines. The tightness of the receiving roller cannot be adjusted simply and effectively, and the adjustment range is limited, which affects the subsequent use range. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a film blowing machine that can adjust the tightness of the winding roller, which solves the problem that the tightness of the receiving roller cannot be adjusted simply an...
