[0035] Start the first motor 7, the first motor 7 drives the threaded rod 8 to rotate, the threaded frame 9 moves up and down along the threaded rod 8, and in turn drives the mounting ring 10 and the paint outlet head 15 to move up and down, start the paint pump 13 and the second motor 24, the paint pump 13 draws the paint in the paint cylinder 12 out, and delivers it to each paint outlet head 15 through the paint pipe 14, and the paint is sprayed from the paint outlet head 15 to the surface of the resin handicraft; at the same time, the second motor 24 drives the gear 25 to rotate, the gear 25 moves along the circumference of the gear ring 26, drives the mounting plate 11 and the paint outlet head 15 to rotate around the center of the mounting ring 10, and realizes all-around painting of the resin handicraft, after painting is completed, close the paint pump 13 and the second motor 24, close the air suction pump 4, press down the operating plate 19, take out the work station table 3, and then the resin handicraft after painting is completed can be taken off.

[0036] The paint tank 12 is provided with an angle adjusting mechanism 28 for driving the rotation of each paint outlet head 15, which comprises a connecting plate 801 detachably arranged in front of the paint tank 12, mounting seats 802 arranged on the connecting plate 801 and close to the paint outlet heads 15, driving screws 803 rotatably arranged on each mounting seat 802, a first rotating plate 804 fixedly arranged on one side of the driving screw 803, a second rotating plate 805 rotatably arranged on the mounting seat 802 and away from the driving screw 803, an inner screw groove 806 arranged on the inner side of the mounting seat 802 and close to the second rotating plate 805, a screw rod 807 screwingly arranged in the inner screw groove 806, the inner side of the screw rod 807 being screwingly connected with the outer side of the driving screw 803, a protrusion 809 being fixedly arranged on the side of the screw rod 807 close to the second rotating plate 805, an inner groove 810 being arranged in the second rotating plate 805 and slidingly connected with the protrusion 809, the screwing direction of the inner screw groove 806 being opposite to that of the driving screw 803, and the paint outlet heads 15 being arranged on the first and second rotating plates 804 and 805.

[0037] When the spray angle of the paint outlet heads 15 needs to be adjusted, the third motor 808 drives the first rotating plate 804 to rotate forward, the first rotating plate 804 drives the driving screw 803 to rotate, and the driving screw 803 drives the screw rod 807 to move. Since the screwing direction of the inner screw groove 806 is opposite to that of the driving screw 803, the rotating direction of the screw rod 807 after being guided by the inner screw groove 806 during the movement will be opposite to that of the driving screw 803. The screw rod 807 is in contact with the inner groove 810 of the second rotating plate 805 through the protrusion 809, drives the second rotating plate 805 to rotate reversely, and the rotating directions of the first and second rotating plates 804 and 805 are opposite, which drives the two paint outlet heads 15 to rotate toward opposite directions, so that the spray angle can be flexibly changed in a large range, and is particularly suitable for resin handicrafts with complex shapes. When the resin handicrafts with non-planar surfaces such as edges and corrugated surfaces need to be painted, the paint outlet heads 15 are directed at opposite angles, which can better cover the concave and convex surfaces, avoid dead angles, and ensure uniform and full paint layers. When the resin handicrafts with planar surfaces need to be painted, the two rotating plates only need to be rotated to an angle perpendicular to the connecting plate 801, at which time the pointing angles of the two paint outlet heads 15 will be the same, ensuring uniform spray area. The angle adjustment is realized automatically through the driving of the third motor 808, without the need for manual adjustment, which reduces the operation difficulty and labor intensity and improves the production efficiency.
