The pipeline for conveying the paint liquid is fixed on the mounting frame 2. In this embodiment, since the mounting frame 2 will move back and forth, the pipeline for conveying the paint liquid must have sufficient length so that it will not be tight when moving with the mounting frame 2, thereby keeping the paint liquid conveying unobstructed.
[0022] See also Figure 1-Figure 3 , wherein the rotating mechanism includes a gear 101, a rack 102, a push block 105 and a push block 2 106. The gear 101 is fixedly connected to one of the rotating shafts 6. The bottom end of the rack 102 is fixedly connected to a support rod 103 and a support rod 2 104 on both sides. A slide is provided on the top of the workbench 4. The support rod 103 and the support rod 2 104 are slidably connected to the workbench 4. The rack 102 is engaged with the gear 101. When the rack 102 slides, it can drive the gear 101 to rotate. The push block 105 and the push block 2 106 are both fixedly connected to the inner side wall of the mounting frame 2, and are used to push the support rod 103 and the support rod 2 104 to slide when the mounting frame 2 slides. The outer cover of the gear 101 is provided with a protective cover 107, and the protective cover 107 is fixedly connected to the support frame 5 to protect the safety of the operator.
[0023] See also Figure 1 、 Figure 2 and Figure 4 , wherein the moving mechanism includes a reciprocating screw 201, a motor 202, a moving seat 203 and a connecting seat 204, the reciprocating screw 201 is rotatably connected to the base 1, the motor 202 is fixedly installed on the base 1, and the output end of the motor 202 is fixedly connected to the reciprocating screw 201, the moving seat 203 is threadedly connected to the reciprocating screw 201, the top of the moving seat 203 is fixedly connected to the connecting seat 204, the connecting seat 204 is fixedly connected to the mounting frame 2, and the bottom end of the connecting seat 204 is fixedly connected to the slider 205, the top of the base 1 is fixedly connected to the slide rail 206, and the slider 205 slides with the slide rail 206.
[0024] See also Figure 1 、 Figure 2 and Figure 5 , wherein the clamping assembly includes a clamping body 301, a bolt 302 and a pressure plate 303. A clamping body 301 is fixedly connected to each rotating shaft 6. A clamping groove is provided on the side of the clamping body 301.

The end of each bolt 302 extending into the clamping groove is fixedly connected to a pressure plate 303.
[0025] In this embodiment, first, place the two ends of the door and window into the clamping grooves of the two clamping bodies 301, and then screw the bolts 302 into the clamping grooves until the pressure plate 303 on the bolts 302 presses the aluminum alloy door and window, and then start the motor 202, and the reciprocating screw 201 is driven by the motor 202 to rotate, driving the moving seat 203 to move along the screw, and the moving seat 203 drives the connecting seat 204 to slide on the slide rail 206, so that the mounting frame 2 and the painting mechanism 3 move from one side of the aluminum alloy door and window to the other side. After the painting is completed, when the push block 105 on the mounting frame 2 contacts the support rod 103, the push block 105 pushes the support rod 103 and the rack 102 to slide, thereby driving the gear 101 to rotate, and the gear 101 drives the rotating shaft 6 and the clamping mechanism 3. The assembly rotates, thereby flipping the aluminum alloy doors and windows to the other side facing up.

The moving seat 203 drives the mounting frame 2 and the spraying mechanism to move back, and the painting mechanism 3 paints the other side of the aluminum alloy doors and windows. After the painting is completed, when the push block 2 106 on the mounting frame 2 contacts the support rod 2 104, the push block 2 106 pushes the support rod 2 104 and the rack 102 to slide, thereby driving the gear 101 to rotate, and the gear 101 drives the rotating shaft 6 and the clamping assembly to rotate, thereby flipping the aluminum alloy doors and windows back to the initial position. After that, the motor 202 stops working when the mounting frame 2 returns to the initial position.
[0026] It should be added that the clamping assembly will inevitably block part of the surface of the doors and windows during painting, and the clamping position is generally touched up with paint after the automatic painting is completed; in order to make the aluminum alloy doors and windows stop rotating after turning 180 degrees, so as to paint the other side of the doors and windows, the number of teeth of the rack 102 can be set to half the number of teeth of the gear 101, so that the gear 101 and the rack 102 engage and rotate half a circle before stopping, or the moving seat 203 can be set to just reach the end of the thread on the reciprocating screw 201 when the doors and windows are turned 180 degrees, and then the moving seat 203 drives the connecting seat 204 and the mounting frame 2 to move in the opposite direction, thereby separating the push block 105 and the support rod 103.
[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
