2. A method for using a single-sided spray coating device for a PE film, characterized in that the single-sided spray coating device for a PE film is a single-sided spray coating device for a PE film according to claim 1, comprising the following steps:
S1, when a PE film enters the tensioning roller, adjusting the roller seat through the tensioning screw rod, adjusting proper tensioning force, enabling the PE film to enter a leveling device, adjusting through the second roller of the leveling device, adjusting the sliding block through the leveling screw rod in the adjusting process to finish adjusting the second roller, enabling the PE film to be positioned at the same horizontal position with the bottom surface of the brushing roller, enabling device paper to just pass through the lower surface of the brushing roller, spraying the PE film in advance before the PE film enters the brushing roller, pre-spraying the PE film through a spraying nozzle of the spraying device, and spraying by using the spraying nozzle, wherein the concentration of glue used for spraying is low relative to that of brushing glue, so that the spraying is convenient to use the spraying nozzle for spraying, and the PE film can be better attached in the later brushing process, and after spraying is finished;
S2, brushing PE films through the brushing plate, brushing glue on the lower side of the roller plate in the brushing roller in the brushing process, finishing brushing the PE films through the brushing micropores on the surface of the roller, wherein the brushing roller rotates to brush, the roller plate is obliquely and fixedly arranged in the roller and does not rotate along with the rotation of the roller in the brushing process, so that the brushing glue is prevented from rolling to the upper end of the roller, the brushing glue in the roller can be scraped, the brushing glue is always positioned at the lower end of the roller, the brushing process is accelerated, and the brushing is finished;
S3, uniformly smearing the upper smearing suction block on the smearing device on the right side of the smearing roller, collecting redundant smearing glue at the same time, collecting the upper smearing suction block in the collecting process, supporting the lower smearing suction block, wherein the upper smearing suction block is a sponge suction block capable of absorbing the smearing glue, enabling the smearing glue to enter the upper smearing suction block, extracting the smearing glue in the upper smearing suction block through the negative pressure tank, entering the glue collecting tank, collecting the glue through the glue collecting tank, finishing glue collecting, and simultaneously enabling the temperature in the negative pressure tank to be 50-60 ℃ to prevent the smearing glue from solidifying in the collecting process.
