When the plate is placed on the driving roller 41 and the driven roller 42, the plate will move along the length direction of the frame 1 under the action of friction, thereby realizing the feeding and conveying of the plate, so as to realize the assembly line painting work of the plate.

As shown in Figures 2 and 3, multiple electric push rods 11 are installed at equal intervals on both side walls of the frame 1. The multiple electric push rods 11 are evenly spaced along the length direction of the frame 1. The extension and retraction directions of the electric push rods 11 on the two inner walls of the frame 1 are relatively arranged along the width direction of the frame 1. The output end of each electric push rod 11 is rotatably connected to a vertically arranged guide roller 12 through a support frame.

During the movement and feeding of the plate, the first motor 21 is started to drive the reciprocating screw 22 to rotate, so that the slider 23 drives the atomizing nozzle 24 to reciprocate along the width direction of the frame 1. When the conveyed plate moves to the bottom of the atomizing nozzle 24, the conveying of the plate is stopped, and the pump body 31 is started to extract the paint in the paint bucket and spray it on the surface of the plate through the atomizing nozzle 24.

When the plates are transported to the bottom of the atomizing nozzle 24, the transport of the plates is stopped first, and the paint is extracted and transported to the atomizing nozzle 24 by starting the pump body 31 and sprayed out through the atomizing nozzle 24. During the spraying process of the atomizing nozzle 24, the reciprocating screw rod 22 is driven to rotate by starting the first motor 21, so as to drive the slider 23 to drive the atomizing nozzle 24 to move back and forth.

When the plate is transported to the bottom of the ventilation pipe 51, the hot air in the ventilation pipe 51 is ejected from the air outlet pipe 52 to blow and dry the paint on the plate. During the drying process of the plate, the reciprocating screw 22 drives the multiple rotating shafts 54 and the spiral plate 541 in the ventilation pipe 51 to rotate through the driving mechanism 6. The spiral plate 541 guides the hot air ejected from the air outlet pipe 52, so that the hot air rotates and gently touches the surface of the plate to dry the paint, thereby improving the painting quality of the plate;

S3: After the spraying and drying of the plates are completed, the plates are removed one by one for collection and sorting so as to carry out subsequent processing on the plates.

Under the cooperation of the first sprocket 44, multiple second sprockets 45 and the chain 46, the driving roller 41 drives multiple driven rollers 42 to rotate. When the plate is placed on the driving roller 41 and the driven roller 42, the plate is driven to be transported along the length direction of the frame 1 under the action of friction, so that the plate passes through the first cover body 2 and the second cover body 5 in turn, so as to achieve painting and drying of the plate surface. During the plate conveying and feeding process, start the first motor 21 to drive the reciprocating screw rod 22 to rotate, so that the slider 23 drives the atomizing nozzle 24 to reciprocate along the width direction of the frame 1. When the conveyed plate moves When the atomizing nozzle 24 moves to the bottom, the conveying of the plate is stopped first, and the paint is pumped out and conveyed to the atomizing nozzle 24 by starting the pump body 31 and sprayed out through the atomizing nozzle 24. During the painting process of the atomizing nozzle 24, the reciprocating screw rod 22 is driven to rotate by starting the first motor 21, so that the slider 23 drives the atomizing nozzle 24 to move back and forth. During the reciprocating movement of the atomizing nozzle 24, the paint is evenly sprayed on the surface of the plate; when the atomizing nozzle 24 completes a reciprocating movement, the plate is fed for a displacement, and then the atomizing nozzle 24 is driven to reciprocate and spray paint again by the first motor 21, and this cycle is repeated until the painting of the plate surface is completed, so as to realize the automatic painting of the plate surface;

After the painting is completed, the plate is transported to the inside of the second cover 5, and the hot air is blown into the ventilation pipe 51 by starting the hot air blower 53 and blown out through the air outlet pipe 52. When the plate is transported through the bottom of the ventilation pipe 51, the hot air blown out of the air outlet pipe 52 dries the paint on the surface of the plate, so that the paint on the plate surface dries quickly, so that the staff can collect and sort the plates;

When the air outlet 52 sprays hot air to dry the paint on the board surface, the reciprocating screw 22 drives the driving shaft 61 to rotate through the transmission assembly 62. Under the meshing cooperation of the first bevel gear 63 and the second bevel gear 64, the driving shaft 61 drives the multiple rotating shafts 54 and the spiral plate 541 to rotate. During the rotation of the spiral plate 541, the hot air blown out from the air outlet 52 is guided, so that the hot air rotates and gently caresses the board surface, thereby reducing the possibility of the board surface paint being dented due to excessive direct wind force, thereby improving the quality of the board surface painting.
