[0048] In summary, the working principle of the present invention is as follows: the metal box to be sprayed is placed on the top of the supporting truncated table 10, and the metal box can be fixed by magnetic attraction by setting a strong magnet 101. When the metal box is sprayed, the pump body 63 and the drive motor 3 can be started by the controller (not shown in the figure), and the pump body 63 can transport the material in the inner cavity of the liquid storage tank 62 to the inner cavity of the nozzle 6 through the hose 61. When the power output shaft of the drive motor 3 rotates, the reciprocating screw 4 fixed on the shaft end of the power output shaft of the drive motor 3 can be rotated, and the reciprocating screw 4 can be moved outside the reciprocating screw 4. The screw nut 5 around the nozzle 6 can move up and down reciprocatingly under the limit of the limit block 51 and the limit rod 52. During the spraying process on one side of the metal box, the cleaning cotton 74 can be tightly attached to one side of the metal box with the coordinated use of the telescopic rod A734, the spring A735 and the cleaning cotton 74 to wipe off the dust on the surface to avoid affecting the spraying effect of the nozzle 6. When the nozzle 6 moves downward, the rack plate 92 can be moved downward, and then the rotating gear 93 meshing with the rack plate 92 can be rotated, so that the rotating gear 93 fixed on the rotating gear 93 can be rotated. The drive gear holder 94 rotates, and the arrangement of the rack plate 92 and the transmission gear holder 95 cannot rotate the transmission gear holder 95. When the rack plate 92 moves upward, the transmission gear holder 95 can be rotated, and then the T-shaped worm 98 can be rotated, so that the worm wheel 99 meshing with the T-shaped worm 98 can be rotated. When the nozzle 6 moves to the highest point, the support round table 10 can be rotated to 90 degrees. When the nozzle 6 moves downward, the other side of the metal box can be sprayed without manual turning over, thereby improving the efficiency of metal box spraying. When the nozzle 6 moves downward to a certain position, the L-shaped guide rod B87 contacts the control switch 88, thereby energizing the two electromagnets 85. Under the action of magnetic force, the magnetic strip 84 can move to the other side, thereby separating the cleaning cotton 74 from one side of the metal box. When the nozzle 6 moves to the highest point, the L-shaped guide rod A86 can contact the adjacent control switch 88, thereby deenergizing the two electromagnets 85. With the coordinated use of the telescopic rod B82 and the spring B83, the cleaning cotton 74 can contact the surface of the metal box. After the spraying is completed, the top and bottom of the metal box can be sprayed through other equipment.
