[0002] Metal doors and windows are classified as enclosure components or partition components depending on their location, and have different design requirements. They must have functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fireproofing. New requirements include energy conservation. In cold regions, heat loss through gaps in doors and windows accounts for about 25% of the total heating heat consumption. The airtightness requirements of metal doors and windows are an important part of energy-saving design.
[0003] Before and after the assembly of metal doors and windows, the outer walls of their unit modules are painted to make them waterproof and rustproof. In the existing technology, the painting of doors and windows is generally carried out directly using a painting device without pre-dust removal of the unit modules, resulting in inconsistent painting quality. To address this, we propose a painting device for metal door and window construction that can automatically remove dust. Utility Model Content

[0008] By adopting the above technical solution, the material can be effectively vacuumed and dried.
[0009] The present invention is further configured such that a first air box is installed at the top of the dust collection ring and a second air box is installed at the top of the drying ring. An exhaust fan is installed inside the first air box and the exhaust fan is connected to the dust collection port. A blower and an electric heating grid are installed inside the second air box and the blower is connected to the air outlet.
[0010] By adopting the above technical solution, the air supply effect of the dust collection ring and the drying exchanger is achieved.
[0011] The present invention is further configured such that a filter box is installed at the top of the paint spraying ring between the second air box and the first air box, and the outer walls of both the first air box and the second air box are connected to an air pipe that communicates with the first air box.

[0014] By adopting the above technical solution, the dust collection box can be easily retrieved.
[0015] In summary, the present invention has the following main advantages:
[0016] 1. This utility model, by setting up a dust suction ring and a drying ring, allows for automatic painting during spraying. A small pump is activated, drawing paint from the storage tank into the supply pipe. The spray nozzle then draws paint from the supply pipe and sprays it onto the outer wall of the material. Simultaneously, an electric guide rail drives the base to move, which in turn moves the spraying ring, achieving fully automatic painting. During painting, the dust suction ring and drying ring operate synchronously. Specifically, the dust suction port in the dust suction ring removes dust from unpainted areas, preventing dust from affecting the painting. Dust-laden gas flows from the first air chamber into the second air chamber, where a blower heats the gas through an electric heating grid before spraying it from the nozzle, drying the painted areas. This improves both painting quality and work efficiency.
[0017] 2. This utility model incorporates a filter box. During the process of gas flowing from the first gas box into the second gas box, the gas passes through the filter box, which filters the gas. Specifically, after entering the filter box, the gas blows the filter screen, compressing the spring and moving it closer to the dust collection trough. As the gas passes through the filter screen, dust particles are intercepted, thus purifying the gas. Some dust adheres to the filter screen, while the rest falls into the dust collection trough. After the painting operation is completed, the filter screen resets under the action of the spring and bounces back and forth. The dust adhering to the filter screen falls into the dust collection trough during this repeated bouncing, achieving a self-cleaning effect. The dust falling into the dust collection trough is eventually collected in the dust collection box. When the dust collection box is full, it can be removed by the handle for cleaning and replacement. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0024] The embodiments of this utility model will be described below based on its overall structure.
[0025] A spray painting device for metal door and window construction, such as Figure 1-4As shown, the device includes a paint spraying ring 1, with multiple sets of annularly distributed paint spray nozzles 2 installed on the inner side of the paint spraying ring 1. A liquid supply pipe 3 for supplying paint to the paint spray nozzles 2 is installed inside the paint spraying ring 1. Liquid storage tanks 4 are installed on both sides of the paint spraying ring 1, and a small pump 5 is installed between the liquid storage tank 4 and the liquid supply pipe 3. A base 6 is fixedly connected to the bottom end of the paint spraying ring 1, and a base plate 7 is provided below the base 6. A sliding groove 8 is opened inside the base plate 7, and an electric guide rail 9 is installed inside the sliding groove 8. The base 6 is adapted to the electric guide rail 9 and is sleeved on the outer wall of the electric guide rail 9.
[0026] Furthermore, in this embodiment, a dust suction ring 10 is provided on one side of the paint spraying ring 1, and multiple sets of dust suction ports 11 are distributed in a ring on the inner side of the dust suction ring 10. A drying ring 13 is provided on the other side of the paint spraying ring 1, and multiple sets of air blowing ports 14 are distributed in a ring on the inner side of the drying ring 13.
[0027] Please see Figure 1 The top of the dust collection ring 10 is equipped with a first air box 12, and the top of the drying ring 13 is equipped with a second air box 15. The first air box 12 is equipped with an exhaust fan, which is connected to the dust collection port 11. The second air box 15 is equipped with a blower and an electric heating grid, which is connected to the air outlet 14, thus realizing the integrated function of dust collection and drying of materials.
[0028] Please see Figure 3-4 A filter box 16 is installed at the top of the paint spraying ring 1 between the second air box 15 and the first air box 12. The outer walls of the first air box 12 and the second air box 15 are connected to air pipes that communicate with the first air box 12. A filter screen 17 is installed inside the filter box 16. A dust collection groove 18 is opened on one side of the filter screen 17 inside the filter box 16. A spring 19 installed inside the filter box 16 is connected to the other side of the filter screen 17. The filter screen 17 is slidably sealed to the inner wall of the dust collection groove 18 to achieve the function of filtering dust.
[0029] Please see Figure 4 Below the dust collection trough 18, a dust collection box 20 is provided in the inner wall of the filter box 16, and a handle extending to the outside of the filter box 16 is fixed to the end of the dust collection box 20 to facilitate easy handling of the dust collection box 20.
[0030] The working principle of this utility model is as follows: When spraying paint, a small pump is started. The small pump 5 will draw paint from the storage tank 4 into the supply pipe 3. Then the spray nozzle 2 will draw paint from the supply pipe 3 and spray it onto the outer wall of the material to realize the painting operation of the material.
[0031] At the same time, the electric guide rail 9 will drive the base 6 to move, and the base 6 will in turn drive the paint spraying ring 1 to move, realizing the fully automatic paint spraying effect on the material. While the paint is being sprayed, the dust suction ring 10 and the drying ring 13 will also run synchronously.
[0032] Specifically, the suction port 11 in the suction ring 10 will vacuum the unpainted area to prevent dust from affecting the painting. The dust-containing gas will flow into the second air box 15 through the first air box 12. Therefore, the blower in the second air box 15 will cause the gas to be heated by the electric heating grid and then sprayed out from the jet port 14 to achieve the drying effect of the painted area, which improves the painting quality and also improves the work efficiency.
[0033] Furthermore, during the process of the gas in the first gas box 12 being introduced into the second gas box 15, the gas will pass through the filter box 16, which will filter the gas. Specifically, after the gas enters the filter box 16, the gas will blow the filter screen 17 and compress the spring 19 to move it to a position close to the inner wall of the dust collection tank 18. Then, when the gas passes through the filter screen 17, the dust contained in the gas will be intercepted by the filter screen 17, thereby achieving the purification effect of the gas. Some of the dust on the filter screen 17 will adhere to the filter screen 17, while the other part will fall into the dust collection tank 18.
[0034] After the painting operation is completed, the filter screen 17 will reset under the action of the spring 19 and bounce back and forth. Therefore, the dust adhering to the filter screen 17 will fall into the dust collection tank 18 during the repeated bouncing of the filter screen 19, thus achieving the self-cleaning function of the filter screen 17. The dust that falls into the dust collection tank 18 will eventually fall into the dust collection box 20 and be collected. When the dust collection box 20 is full, it can be removed by the handle for cleaning and replacement.
