The invention discloses an automatic spraying
assembly line based on a
metal covering protective layer and capable of transversely moving and rotatably swinging. The automatic spraying
assembly line structurally comprises a feeding object stage, a transverse moving and rotatably swinging
machine frame, a
human machine interface board, an axle wheel top cover groove, a distribution motor box, a
conveyor belt plate box and a finished storage cabinet. According to the automatic spraying
assembly line, the cooperation of the transverse moving and rotatably swinging
machine frame and the axle wheeltop cover groove is realized, the arc surface spraying operation is carried out through the bending rotary swinging of rotary
brush plates in cooperation with a track, and thus the paint spraying ofthe
metal covering protective layer carries out one-step in-place operation; and the spraying rotary
brush plates and hoisting clamp seats are combined into a bidirectional clamping plate for sprayingthe sliding and brushing
metal surface of the front end and the rear end of the bidirectional clamping plate, the vertical metal surface is transferred back along the arc surface to form a rotatableswinging sweeping effect, and residual paint liquid bonding the surface forms a
sieve brush cleaning effect after a rotary
propeller wind wheel band is convoluted, so that liquid drops are rapidly slipped off, the quality and key effect of the single-side protective layer at the later stage is facilitated, the super-thin homogeneous
processing of the paint surface is also facilitated, and the
production line spraying qualification rate is improved.
