[0028] Working principle: When the luggage box needs to be painted, first pull the connecting rod 27 to slide inside the protective cover 3, so as to achieve the effect of adjusting the limit according to the luggage box. At this time, the luggage box is transported by starting the transmission roller 1 4, the transmission roller 2 5 and the transmission roller 3 6. At this time, the transmission pump 1 7 is started. At this time, the paint inside the storage tank 2 is transferred to the inside of the connecting hose 8 through the transmission pump 1 7. At the same time, the hydraulic cylinder 13 is started, and the connecting shaft 14 is driven to move back and forth by the hydraulic cylinder 13. At this time, the movement of the connecting shaft 14 drives the nozzle 11 below the L-shaped pipe 10 to spray the paint back and forth.

[0029] Secondly, when the luggage box initially enters above the transmission roller 1 4, the transmission pump 2 15 is started. At this time, the paint in the storage tank 2 is synchronously transmitted to the transmission pipe 16 through the transmission pump 2 15. At this time, the paint is diverted through the transmission pipe 16, so as to achieve the effect of evenly distributing the paint to the vicinity of the nozzle 2 17 and the nozzle 3 18. At this time, the cooperation of the nozzle 2 17 and the nozzle 3 18 further achieves the effect of multi-directional and efficient spraying of the luggage box. At the same time, the dripping paint is collected by the collection box 19 and the fixed box 22, and then, through the cooperation of the drainage slope 20, the excess paint is transmitted to the inside of the filter box 23 for filtration. At this time, it is transmitted to the inside of the storage tank 2 through the collection hopper 21, thereby achieving the effect of recycling the paint. When the luggage box paint is completed and passes above the transmission roller 3 6, the air outside the protective cover 3 is filtered through the protective cover 25 by starting the fan 24 and transmitted to the luggage box, thereby achieving the effect of quickly drying the luggage box.
