The invention discloses a coating device for the striking surface layers of matches. The coating device comprises a device body, wherein a transport cavity is formed in the device body, a matchbox isarranged in the transport cavity, and a to-be-coated end surface of the matchbox is arranged vertically; eight sets of conveying devices are arranged on the outer side of the conveying cavity, the conveying devices are evenly disposed horizontally from right to left along the conveying cavity, and the conveying devices are connected through power; and the conveying devices work so as to drive thematchbox to move leftwards. Phosphor slurry is coated on both side surfaces of the matchbox through the coating device, and after one side is coated, the coated surface is dried through an air dryingdevice; and the other surface of the matchbox is turned upwards through a flipping device, the coating work of the next step is performed, and the process has automatic operation, a high speed and high efficiency.
