The single-side glue spraying device for the PE film as claimed in claim 1, wherein the upper coating suction block is a sponge suction block, the upper coating suction block is mounted on the device base through an upper coating bracket, a negative pressure tank is mounted at the upper end of one side of the upper coating suction block, the upper coating suction block is mounted at a port of the negative pressure tank, a glue solution collecting tank is mounted at one side of the negative pressure tank, a glue solution collecting box is mounted at the lower end of the glue solution collecting tank, and a negative pressure fan is mounted at the upper end of the negative pressure tank.
6. A single-side glue spraying device for PE films and a use method thereof are characterized in that the single-side glue spraying device for the PE films is the single-side glue spraying device for the PE films, which is disclosed by any one of claims 1 to 5 and comprises the following steps:
s1: after a PE film enters the tensioning roller, the roller seat is adjusted through the tensioning screw, after a proper tensioning force is adjusted, the PE film enters the leveling device, the PE film is adjusted through the second roller of the leveling device, the sliding block is adjusted through the leveling screw in the adjusting process to complete adjustment of the second roller, the PE film and the bottom surface of the painting roller can be in the same horizontal position, device paper just passes through the lower surface of the painting roller, the PE film is firstly sprayed before entering the painting roller, the PE film is pre-sprayed through a spraying nozzle of the spraying device, and the spraying nozzle is used for spraying, so that the concentration of glue used for spraying is low relative to the glue used for painting, the spraying nozzle is convenient to spray, the PE film can be better attached in the later painting process, and the spraying is completed;
s2: the coating of the PE film is performed through the coating plate, the coating glue is arranged on the lower side of the roller plate in the coating roller in the coating process, the coating of the PE film is completed through the coating micropores on the surface of the roller, the coating roller is rotationally coated in the coating process, the roller plate is obliquely and fixedly arranged in the roller and does not rotate along with the rotation of the roller, so that the coating glue is prevented from rolling to the upper end of the roller, the coating glue in the roller can be scraped, the coating glue is always positioned at the lower end of the roller, the coating process is accelerated, and after the coating is completed;
s3: the coating device is characterized in that the coating device comprises a coating roller, a coating suction block, a lower coating support block, a sponge suction block, a glue solution collecting tank and a negative pressure tank, wherein the coating suction block on the coating device on the right side of the coating roller is used for uniformly coating and collecting redundant coating glue, the upper coating suction block is used for collecting the coating glue in the collecting process, the lower coating support block is used for supporting, the upper coating suction block is a sponge suction block and can absorb the coating glue, the coating glue enters the upper coating suction block, the coating glue in the upper coating suction block is extracted out through the negative pressure tank and enters the glue solution collecting tank, the glue solution collecting tank is used for collecting the coating glue, and meanwhile, the temperature in.
