The invention discloses an automatic columnar product protection layer wrapping device. The automatic columnar product protection layer wrapping device is composed of a blank conveying mechanism, a protection film supply mechanism, a double faced adhesive tape supply and conveying mechanism, a protection film glue coating mechanism, a glue peeling mechanism, a winding mechanism, a shearing mechanism, a supporting mechanism and the like. After a low-tension protection film roll and a double faced adhesive tape roll pass through the glue coating mechanism under the action of respective supply traction force, a glue layer is bonded to the inner side of the protection film, and body paper is still left on the outer side of the glue layer, wherein the glue coating mechanism is composed of double rollers. After the protection film continuously passes through the glue peeling mechanism and the body paper is peeled, protection film rolling wrapping is conducted. According to the automatic columnar product protection layer wrapping device, rapid and automatic winding of a low-tension protection film on a columnar product can be achieved; the product packaging and delivery efficiency is improved in a mechanical and standard manner, and the production cost is reduced; and the wrapping quality is reliable, performance is stable, and the production efficiency is effectively improved.
