Swing-type protecting film folding device

Abstract

The invention discloses a swing-type protecting film folding device comprising a bottom plate and a side plate. A fixed plate and a movable plate are further arranged on the bottom plate; the bottom of the movable plate and the upper end face of the bottom plate are connected through a sliding mechanism; a fixing plate is further arranged at the left end of the upper end face of the bottom plate; a screw is arranged on the fixing plate; a rotating shaft is arranged on the side plate; the end, located on the left side of the side plate, of the rotating shaft is fixedly connected with a fan-shaped swing plate; a transverse shaft perpendicular to the fan-shaped swing plate is arranged at the top end of the fan-shaped swing plate; a protecting film winding wheel is arranged on the transverse shaft; the lower ends of two sliding blocks are fixedly connected with an upper rack; a double-face rack parallel to the upper rack is arranged below the upper rack, and the two ends of the upper rack are fixedly connected with the double-face rack through connecting rods; and an incomplete gear is arranged on a rotating shaft of a driving motor, and the lower end of the double-face rack is engaged with the gear. The structure is simple, positive and reverse rotation of the driving motor is not needed, the folding efficiency of a protecting film is improved, the protecting film is folded orderly, operation is easy and convenient, and practicability is high.

Description

technical field [0001] The invention relates to a protective film production device, in particular to a swing-type protective film folding device. Background technique [0002] According to the application, the protective film can be divided into digital product protective film, car protective film, household protective film, food fresh-keeping protective film and so on. With the popularization of digital products such as mobile phones in China, protective film has gradually become a general term for screen protective film, and its functions in the field of screen protective film are also varied. In the production of protective film, it is usually necessary to use protective film It is folded so that the protective film can be easily flattened, and the general protective film folding requires the driving motor to achieve forward and reverse rotation to realize the folding of the protective film, which may require a pause in the folding of the protective film, and also reduce...
