s2, after gas cleaning, the glue supply device starts a glue guide head in the spray coating device to guide out liquid glue, the liquid glue passes through the brush body part and then is coated on the surface of the raw material from the bottom end of the brush body part, and then the liquid glue is irradiated for a short time through the ultraviolet irradiation plate to increase the viscosity of the glue;
s3, starting the first driving motor and the second driving motor to drive the coating roller assembly to move relatively, and extruding the raw material coated with the colloid to enable the coated colloid to be uniform; the redundant colloid stuck on the coating roller assembly is guided into a flow guide part on the outer side of the shell through the cleaning assembly, and then is recycled into the residue collecting barrel;
and S4, detecting glue liquid remained on the upper coating roller and the lower coating roller by the camera unit, starting a plurality of telescopic hydraulic cylinders in the tightening device when excessive glue residue is detected, and further squeezing the arc cover to tighten the two ends, so that the scraper scrapes the coating rollers.
