US Patent 10479635 Stretch film dispenser with tension adjustment device

A stretch film dispenser with a tension adjustment device includes a frame. The frame is provided with a film dispensing unit and the tension adjustment device. The tension adjustment device includes an adjustment rod. One end of the adjustment rod is threadedly connected with an adjustment unit. An elastic unit is connected between the frame and the film dispensing unit. When the adjustment unit rotates along the adjustment rod to generate downward axial displacement, the adjustment unit pushes the frame and the elastic unit to press the film dispensing unit, so that the film dispensing unit can be quickly adjusted in a different tension state when the film of the film roll is stretched.
