Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy window processing, in particular to an aluminum alloy window processing and painting device. Background Art

[0002] Aluminum alloy windows are windows with frames and sash structures made of aluminum alloy architectural profiles. They are divided into ordinary aluminum alloy doors and windows and thermally insulated aluminum alloy doors and windows. Aluminum alloy itself is easy to extrude, the cross-sectional dimensions of the profiles are precise, and the processing accuracy is high. Therefore, many owners choose to use aluminum alloy doors and windows in decoration.

[0003] At the same time, if aluminum alloy windows are not painted, they are prone to rust, because aluminum alloy will turn gray due to oxidation during long-term use. Painting can effectively prevent the oxidation and corrosion of aluminum alloy doors and windows, protecting them from erosion by the external environment.

[0004] For example, the painting device for processing thermally broken aluminum alloy windows with application number 202322111200.1 has a painting range switching mechanism. The strip-shaped painting port at the bottom of the paint box is completely exposed to paint the vertical surface of the square window frame. When the horizontal surface of the square window frame is at the bottom of the paint box, the sealing plate is controlled to be retracted into the bottom of the paint box and the middle part of the strip-shaped painting port is blocked to adapt to the horizontal range of the square window frame for painting. The strip-shaped painting port of the paint box can be flexibly switched to effectively improve the comprehensiveness and efficiency of painting the upper part of the square window frame. However, the device still has certain defects.

[0005] After the aluminum alloy window is sprayed with paint through the spray nozzle, residual paint will adhere to the lower surface of the spray nozzle and cannot be cleaned. As a result, the paint will solidify at the position of the spray nozzle after a long time, causing the spray nozzle to be blocked.

[0006] Therefore, we propose a kind of aluminum alloy window processing and painting device, in order to solve the problems raised in above-mentioned. Utility Model Content

[0007] The purpose of the present utility model is to provide an aluminum alloy window processing and painting device to solve the problem raised in the above-mentioned background technology that after the aluminum alloy windows are sprayed through the paint spray port on the current market, residual paint will adhere to the lower surface of the paint spray port and it will be impossible to clean it.

A control valve is installed on the paint drain pipe. The collecting box 10 can collect excess paint, and the solidified paint can be discharged through the paint drain pipe. A spring 12 is installed on the right upper surface of the collecting box 10. A fixed block 13 is installed on the left inner wall of the paint spray box 1, and a built-in groove 14 is opened inside the fixed block 13. A baffle 16 is installed inside the built-in groove 14 through a telescopic spring 15. The right end of the baffle 16 is installed through a connecting rod 17. Equipped with a paint spraying device, the paint spraying device includes a paint box 18, a paint inlet pipe 19 and an atomizing nozzle 20. The paint box 18 is installed at the right end of the connecting rod 17, and the paint box 18 is designed in a rectangular frame structure. The lower surface of the paint box 18 is installed with an atomizing nozzle 20, and the paint inlet pipe 19 is installed above the paint box 18. The connecting rod 17 is slidably connected to the fixed block 13. The paint inlet pipe 19 can be provided with an electric control valve. After the aluminum alloy window is fixed, the electric control valve on the paint inlet pipe 19 is opened, and the paint can be transported to the paint box 18 through the paint inlet pipe 19, and then transported to the atomizing nozzle 20 through the paint box 18 for spraying, so as to spray paint on the four sides of the aluminum alloy;

[0037] A connecting plate 21 is installed on the right inner wall of the paint spray box 1, and a first transmission shaft 22 is installed on the connecting plate 21 through a fixed bearing, and a cam 23 and a first bevel gear 24 are installed at the upper and lower ends of the first transmission shaft 22 respectively. A second transmission shaft 25 is installed on the left side of the second servo motor 3 through the output shaft, and a shift block 27 is installed on the second transmission shaft 25 through a rotating block 26. A second bevel gear 28 is installed on the left end of the second transmission shaft 25. The second bevel gear 28 and the first bevel gear 24 are perpendicular to each other and mesh with each other. The rotating block 26 and the shift block 27 are located above the spring 12. After the aluminum alloy window is painted, the second servo motor 3 is started. The second servo motor 3 drives the second transmission shaft 25 to rotate through the output shaft. The second transmission shaft 25 drives the rotating block 26 and the shift block 27 to rotate. The shift block 27 can intermittently shift the spring 12, thereby driving the upper surface of the collection box 10 to vibrate through the spring 12. This facilitates the transportation of paint from the upper surface of the collection box 10 to the interior of the collection box 10. At the same time, the rotation of the second transmission shaft 25 drives the second bevel gear 28 to rotate, the second bevel gear 28 drives the first bevel gear 24 to rotate, the first bevel gear 24 drives the first transmission shaft 22 to rotate, and the first transmission shaft 22 drives the cam 23 to rotate, so that the cam 23 intermittently squeezes the paint box 18, and the paint box 18 drives the baffle 16 to move to the left through the connecting rod 17. At this time, the telescopic spring 15 is in a stretched state, and the protruding end of the cam 23 rotates to move away from the paint box 18. The force on the paint box 18 disappears, and the baffle 16 moves to the right under the action of the rebound force of the telescopic spring 15. The baffle 16 drives the paint box 18 to move to the right through the connecting rod 17, and the cycle is repeated, thereby causing the paint box 18 to shake left and right, causing the paint on the atomizing nozzle 20 below the paint box 18 to fall into the collection box 10 and its interior under the force, thereby preventing the atomizing nozzle 20 from being blocked.

[0038] Working principle: When using the aluminum alloy window processing and painting device, first, place the aluminum alloy window between the positioning bars 8, and the first servo motor 2 drives the left and right screws 4 to rotate through the output shaft, and the left and right screws 4 drive the first slider 5 and the second slider 6 to move in opposite directions, and the first slider 5 and the second slider 6 drive the positioning bar 8 below to move in opposite directions to fix the aluminum alloy window, open the electric control valve on the paint inlet pipe 19, and the paint can be transported to the paint box 18 through the paint inlet pipe 19, and then transported to the atomizing nozzle 20 through the paint box 18 to be sprayed, and the four sides of the aluminum alloy are painted.

[0039] After the aluminum alloy window is painted, the second servo motor 3 is started. The second servo motor 3 drives the second transmission shaft 25 to rotate through the output shaft. The second transmission shaft 25 drives the rotating block 26 and the shifting block 27 to rotate. The shifting block 27 can intermittently shift the spring piece 12, thereby driving the upper surface of the collection box 10 to vibrate through the spring piece 12, so that the paint on the upper surface of the collection box 10 is transported to the inside of the collection box 10. At the same time, the rotation of the second transmission shaft 25 drives the second bevel gear 28 to rotate, the second bevel gear 28 drives the first bevel gear 24 to rotate, the first bevel gear 24 drives the first transmission shaft 22 to rotate, and the first transmission shaft 22 drives the cam The wheel 23 rotates, causing the cam 23 to intermittently squeeze the paint box 18. The paint box 18 then drives the baffle 16 to the left via the connecting rod 17. At this point, the telescopic spring 15 is in a stretched state, and the protruding end of the cam 23 rotates away from the paint box 18. The force on the paint box 18 is relieved, and the baffle 16 now moves to the right under the rebound force of the telescopic spring 15. The baffle 16 then drives the paint box 18 to the right via the connecting rod 17. This cycle repeats, causing the paint box 18 to sway left and right, forcing the paint on the atomizing nozzle 20 below the paint box 18 to fall into the collection box 10 and its interior, thereby preventing the atomizing nozzle 20 from becoming clogged. This completes a series of operations. Matter not described in detail in this specification belongs to the prior art known to those skilled in the art.
