Description

Technical Field

[0001] This utility model relates to the field of door and window spraying device, specifically to a uniform spraying device for door and window painting. Background Technology

[0002] In the field of door and window manufacturing and decoration, the painting process is a key link to improve the aesthetics, durability and protective performance of doors and windows. Traditional door and window painting methods include manual spraying and some simple mechanical spraying. These methods have many problems in practical applications, resulting in inconsistent painting effects.

[0003] When manually spraying with a handheld spray gun, the natural swaying of the arm makes it difficult to maintain a constant distance between the spray gun and the surface of doors and windows. If the distance is too close, paint will accumulate in localized areas, creating a "tears"-like dripping effect that severely impacts the appearance of the doors and windows. Conversely, if the distance is too far, the paint atomization particles will dry before reaching the surface, resulting in an "orange peel" or rough "sand texture," which not only affects aesthetics but also wastes a significant amount of paint. Uneven spray gun movement speed is also a common problem. Moving the spray gun too slowly results in an excessively thick paint film, prone to dripping; moving it too quickly leads to an excessively thin paint film with insufficient coverage, resulting in exposed substrate or a "bluish" appearance. Furthermore, if the angle between the spray gun and the surface cannot be maintained perpendicularly, it will cause asymmetrical paint mist distribution, resulting in a thicker paint film on one side of the door or window surface and a thinner film on the other, creating uneven streaks. Additionally, if the overlap between each spray stroke is inaccurate, areas with excessive overlap will have a thicker paint film, while areas with insufficient overlap will exhibit thin streaks.

[0004] Problems with the paint itself should not be ignored. Insufficient mixing of pigments and resins in the paint can lead to inconsistencies in color and gloss during the spraying process. Furthermore, if residual paint is not collected and disposed of in a timely manner during the spraying process, it can result in paint waste. Utility Model Content

[0005] To address the technical problems mentioned above, such as uneven spray gun movement speed, inconsistent distance between the spray gun and doors / windows, inability to maintain a perpendicular angle between the spray gun and the sprayed surface, insufficient mixing of pigments and resins in the paint, and failure to collect and process residual paint in a timely manner, this utility model provides a uniform spraying device for door and window painting.

[0006] A uniform spraying device for door and window painting includes a support frame, with ventilation pipes and electric slide rails fixedly installed on both sides of the support frame. Vacuum nozzles and vacuum pumps are respectively connected at the inner and outer ends of the ventilation pipes. A paint gun is movably mounted on the electric slide rail. A liquid supply tank is installed above the paint gun via a liquid inlet pipe. A stirring rod and a heating rod are installed inside the liquid supply tank. A pad is fixedly installed below the vacuum nozzle. A receiving box is fixedly installed on the outer wall of the pad. An inclined guide plate is fixedly installed below the paint gun.

[0007] Furthermore, the support frame includes a base plate, with vertical plates fixedly installed on both sides of the base plate. One of the vertical plates has an L-shaped structure, and the liquid supply tank is fixedly embedded in the top wall of the L-shaped vertical plate. A covered conveying pipe is installed through the top wall of the liquid supply tank and the bottom wall of the receiving tank.

[0008] Furthermore, the vacuum pump is mounted on the outer wall of another vertical plate via a mounting bracket. The ventilation pipe includes a main pipe and several branch pipes. Both ends of the main pipe are connected to the vacuum pump and several branch pipes, respectively. The other ends of the branch pipes are all connected to a vacuum nozzle, which can adsorb door and window profiles.

[0009] Furthermore, a servo motor is mounted on the outer wall of the liquid supply tank via a mounting bracket, and the stirring rod includes a rotating shaft fixedly mounted on the output end of the servo motor, with several stirring paddles fixedly mounted on the outer wall of the rotating shaft.

[0010] Furthermore, the heating rod is fixedly installed on the inner wall of the liquid supply tank and connected to an external power source. The infusion tube includes a rigid infusion tube and a flexible delivery hose that are connected to it. The top end of the rigid infusion tube is connected to the bottom wall of the liquid supply tank, and a liquid pump and a booster pump are installed sequentially from top to bottom. The top and bottom ends of the flexible delivery hose are connected to the bottom end of the rigid infusion tube and the liquid inlet end of the paint spray gun, respectively.

[0011] Furthermore, the electric slide rail is equipped with a slider, the paint gun is mounted on the outer wall of the slider, the top of the receiving box is an open structure, the inclined lower end of the guide plate is fixedly mounted on the top of the receiving box, and a friction pad is fixedly mounted on the top wall of the pad block.

[0012] Compared with existing technologies, the advantages of this invention are as follows: The paint gun moves linearly up and down on the electric slide rail, ensuring that the spray trajectory of the paint gun is consistent with the door and window profiles. This avoids problems such as asymmetrical paint mist distribution and uneven paint film thickness caused by incorrect spraying angles. Furthermore, it ensures that the paint gun maintains a fixed distance from the door and window surface, guaranteeing a straight-line movement trajectory and preventing uneven painting caused by curved movements. The electric mixer thoroughly mixes the paint evenly in a short time, preventing color differences caused by pigment sedimentation. The high-speed rotation of the stirring roller, combined with the use of the heating rod, ensures thorough mixing of pigments and resins in the paint, guaranteeing paint uniformity and maintaining consistent color and gloss after painting. The vacuum nozzle can hold the door and window profiles, and the receiving box can collect excess paint, preventing waste. Attached Figure Description

The following will refer to the accompanying drawings. Figures 1-4 The present invention will be described in detail with reference to the embodiments.

[0023] A uniform spraying device for door and window painting includes a support frame 1. Ventilation pipes 2 and electric slide rails 3 are fixedly installed on both sides of the support frame 1, for air circulation and vertical sliding of a slider 24, respectively. The support frame 1 includes a base plate, with vertical plates fixedly installed on both sides of the base plate. One of the vertical plates is L-shaped. A liquid supply tank 8 is fixedly embedded in the top wall of the L-shaped vertical plate. A covered feed pipe 14 is installed through the top wall of the liquid supply tank 8 and the bottom wall of the receiving tank 12. By opening the cover, pigment and resin can be added to the liquid supply tank 8 through the feed pipe 14. Residual paint received in the receiving tank 12 can be collected and recycled, processed, and reused, avoiding paint waste.

[0024] The inner and outer ends of the ventilation pipe 2 are respectively connected to a vacuum nozzle 4 and a vacuum pump 5. The vacuum pump 5 is mounted on the outer wall of another vertical plate via a mounting bracket. The ventilation pipe 2 includes a main pipe 15 and several branch pipes 16. The two ends of the main pipe 15 are respectively connected to the vacuum pump 5 and several branch pipes 16. The other ends of several branch pipes 16 are all connected to a vacuum nozzle 4, which can adsorb door and window profiles.

[0025] Start the vacuum pump 5, which generates suction through the main pipe 15 and several branch pipes 16 in sequence, so that the vacuum nozzle 4 can adsorb the door and window profiles. Since a pad 11 is fixedly installed below the vacuum nozzle 4, and a friction pad 25 is fixedly installed on the top wall of the pad 11, the bottom of the door and window profile is placed on the friction pad 25, which can further support the door and window profile. The friction pad 25 can prevent the door and window profile from slipping, and together with the vacuum nozzle 4, it can better fix the door and window profile, making it convenient for subsequent painting.

[0026] A paint gun 6 is movably mounted on the electric slide rail 3. A slider 24 is slidably mounted on the electric slide rail 3. The paint gun 6 is mounted on the outer wall of the slider 24. The slider 24 moves up and down inside the electric slide rail 3, which drives the paint gun 6 to move up and down to spray paint on the door and window profiles.

[0027] Above the paint spray gun 6, a liquid supply tank 8 is installed via an infusion pipe 7. Inside the liquid supply tank 8, there are stirring rods 9 and heating rods 10. A servo motor 17 is installed on the outer wall of the liquid supply tank 8 via a mounting bracket. The stirring rod 9 includes a rotating shaft 18 fixedly installed on the output end of the servo motor 17. Several stirring paddles 19 are fixedly installed on the outer wall of the rotating shaft 18. The heating rod 10 is fixedly installed on the inner wall of the liquid supply tank 8 and is connected to an external power source.

[0028] Turn on the servo motor 17 to drive the rotating shaft 18 to rotate, which in turn drives several stirring paddles 19 to fully mix the pigment and resin, so that the color of each spray is consistent. At the same time, the heating rod 10 can be energized to generate heat to heat the pigment and prevent it from solidifying if left for too long.

[0029] The infusion tube 7 includes a rigid infusion tube 20 and a flexible delivery hose 21 that are connected to it. The top end of the rigid infusion tube 20 is connected to the bottom wall of the supply tank 8, and a liquid pump 22 and a booster pump 23 are arranged sequentially from top to bottom. The top and bottom ends of the flexible delivery hose 21 are connected to the bottom end of the rigid infusion tube 20 and the inlet end of the paint gun 6, respectively.

[0030] Turn on the liquid pump 22 and the booster pump 23 so that the liquid delivery tube 7 can deliver the raw materials in the liquid supply tank 8 to the paint gun 6 for painting. The flexible delivery hose 21 can move up and down with the paint gun 6.

[0031] A receiving box 12 is fixedly installed on the outer wall of the pad block 11. The top of the receiving box 12 is set as an open structure. An inclined guide plate 13 is fixedly installed below the paint gun 6. The inclined lower end of the guide plate 13 is fixedly installed on the top of the receiving box 12.

[0032] Paint that does not adhere to the door frame profile during spraying falls onto the guide plate 13 below and then flows along the guide plate 13 into the receiving box 12 below. The feed pipe 14 can be opened periodically to recover the paint in the feed box 8.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
