Uniform-coating pre-coating film gluing device

The utility model discloses a pre-coating film gluing device capable of uniformly coating, which relates to the technical field of pre-coating film production and comprises a mounting back plate, supporting legs are arranged at two ends of the bottom of the mounting back plate, one side of the mounting back plate is rotatably connected with a first conveying roller, and the other side of the mounting back plate is further rotatably connected with a third conveying roller; according to the glue dispensing gun, glue can be applied to a film material during use through the glue discharging holes and the glue applying roller, the glue discharging holes and the glue applying roller are matched to form a sheet-shaped glue applying layer during glue applying, the situation that a traditional glue dispensing gun is uneven in glue dispensing is avoided, meanwhile, the glue dispensing gun can reciprocate during use through the mounting roller and the applying wheel, and the glue dispensing effect is improved.
