Technical Field

[0001] This utility model relates to the field of irregular metal spraying technology, and more specifically, to a paint spraying device capable of uniformly spraying irregular metals. Background Technology

[0002] Spraying equipment is a product of the reform and opening up, and of the increasingly widespread automation in industrial technology. As the degree of automation increases, the application of spraying production lines is becoming more and more widespread and penetrating into many sectors of the national economy.

[0003] When spraying irregularly shaped workpieces, operators or even machines usually spray the irregularly shaped metal workpieces one side at a time, which is inefficient. In addition, the excess paint generated during the spraying process can easily cause splattering and waste various resources.

[0004] A search revealed that Chinese patent CN215940394U discloses an irregularly shaped metal coating spraying device. By setting up a funnel-shaped protective cover to protect the irregularly shaped workpiece from spraying, it not only avoids the problem of spraying slurry splashing everywhere, but also effectively recovers excess coating, achieving energy-saving and environmental protection effects. It is quite practical and suitable for widespread promotion and use.

[0005] In actual use, some of the spraying pipes of the above-mentioned irregular metal coating spraying equipment are fixed in place, which makes it easy for dead corners to appear when spraying irregular metals, resulting in uneven coating thickness and thus reducing the coating quality. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a paint spraying device capable of uniformly spraying irregularly shaped metals, so as to solve the problems mentioned in the background art.

[0012] By adopting the above technical solution, the paint inside the storage tank can be transported to the spray pipe under the action of the spray pump, thereby facilitating the maintenance of the continuity of the spraying work.

[0013] As a further description of the above technical solution: a motor is installed inside the spray box, and a turntable is fixedly connected to the output end of the motor.

[0016] By adopting the above technical solution, hot air is delivered to the inside of the spray box through the air conveyor ring, ensuring that the metal surface can be fully dried and guaranteeing the uniformity of drying.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. By setting up a spraying assembly, compared with the existing technology, the swing of two spraying pipes can cover the workpiece surface more extensively, which helps to reduce dead corners in the spraying process and makes the paint evenly distributed on irregular metal surfaces, thereby improving the uniformity and integrity of the spraying.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This application discloses a paint spraying device capable of uniformly spraying irregularly shaped metals, including a spraying box 1, and a spraying assembly installed inside the spraying box 1.

[0029] The spraying assembly includes a first stepper motor 2, which is fixedly connected to the upper surface of the spraying box 1. A lead screw 3 is fixedly connected to the output end of the first stepper motor 2. A threaded plate 4 is threadedly connected to the outer side of the lead screw 3. A baffle 5 is fixedly connected to one side of the threaded plate 4. A fixed box 6 is fixedly connected to one side of the baffle 5. A second stepper motor 7 is installed inside the fixed box 6. A drive wheel 8 is fixedly connected to the output end of the second stepper motor 7. A chain 9 is meshed on the outer side of the drive wheel 8. A driven wheel 10 is meshed on the inner side of the chain 9. Spraying pipes 11 are fixedly connected to one side of both the drive wheel 8 and the driven wheel 10. Multiple nozzles 12 are connected to one side of the spraying pipes 11. A sliding groove 1 is provided inside the spraying box 1. 3. The first step motor 2 drives the lead screw 3 to rotate, so that the lead screw 3 can drive the threaded plate 4 to move through the thread. The movement of the threaded plate 4 can drive the baffle 5 to slide inside the slide groove 13. Since the length of the baffle 5 is longer than the opening on one side of the slide groove 13, the baffle 5 can always block the opening on one side of the slide groove 13 when it moves, which can effectively prevent the sprayed paint from splashing to the outside. The drive wheel 8 is connected to the driven wheel 10 through the chain 9 to rotate, so that the two spray pipes 11 can swing and spray on both sides of the irregular metal, which helps to reduce dead corners in the spraying process, ensures uniform distribution of paint, and thus improves the uniformity of spraying.

[0030] Reference Figure 2 and 3 As shown, a storage tank 17 is installed on one side of the spraying box 1. A spraying pump 15 is installed on the upper surface of the storage tank 17. The input end of the spraying pump 15 is connected to a material extraction pipe 16. One end of the material extraction pipe 16 is connected to the storage tank 17. The output end of the spraying pump 15 is connected to a material delivery pipe 18. A distribution box 19 is connected to one side of the material delivery pipe 18. Two delivery hoses 20 are connected to one side of the distribution box 19. One end of the delivery hoses 20 is connected to the spraying pipe 11. Under the action of the spraying pump 15, the paint inside the storage tank 17 can be extracted and delivered to the distribution box 19 through the material delivery pipe 18. The distribution box 19 can evenly disperse the paint into the two delivery hoses 20, thereby maintaining the continuity of spraying by multiple nozzles 12.

[0031] Reference Figure 4and 1 As shown, a motor 21 is installed inside the spray box 1. A turntable 22 is fixedly connected to the output end of the motor 21. A cylinder 23 is installed on the upper surface of the spray box 1. Fixed push rods 24 are installed on both the output end of the cylinder 23 and the upper surface of the turntable 22. The upper fixed push rod 24 is rotatably connected to the output end of the cylinder 23, and the lower fixed push rod 24 is fixedly connected to the upper surface of the turntable 22. A drying mechanism is connected to the inside of the spray box 1. The drying mechanism includes a blower 25, which is fixedly connected to the upper surface of the spray box 1. The output end of the blower 25 is connected to a heating box 26 via an air duct. Multiple electric heating tubes 27 are installed inside the heating box 26. An air supply pipe 28 is connected to one side of the heating box 26, and an air supply ring 29 is connected to one end of the air supply pipe 28. The air supply ring 29 is fixedly connected to the inside of the spray box 1. Under the action of the blower 25, the heat emitted by the multiple electric heating tubes 27 in the heating box 26 can be transported to the air supply ring 29 through the air supply pipe 28, so that the air supply ring 29 can evenly distribute the heat to the inside of the spray box 1, ensuring that the metal surface can be fully dried and that the hot air can form a stable flow on the metal surface, thereby enhancing the drying effect.

[0032] Working principle of this utility model: This utility model designs a paint spraying device capable of uniformly spraying irregularly shaped metals. The specific structure is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation of various structures, when it is necessary to spray the irregularly shaped metal, the irregularly shaped metal is first placed on the fixed top rod 24 on the upper surface of the turntable 22. Then, the cylinder 23 is activated, which pushes the upper fixed top rod 24 downward to the top of the irregularly shaped metal, thereby fixing the irregularly shaped metal. Then, the motor 21 is activated, which drives the turntable 22 to rotate, thereby allowing the irregularly shaped metal to rotate. Then, the first stepper motor 2 is activated, which drives the lead screw 3 to rotate. The lead screw 3 drives the threaded plate 4 to move up and down through the thread. The threaded plate 4 can drive the baffle 5 to slide inside the slide groove 13. Since the length of the baffle 5 is longer than the opening on one side of the slide groove 13, the baffle 5 can block the opening on one side of the slide groove 13 when it slides inside the slide groove 13, thereby preventing spraying from splashing at the opening. When the baffle 5 moves, it can drive the fixed box 6 to move, so that the fixed box 6 can drive the two spray pipes 11 to move into the irregularly shaped metal. The spraying pump 15 is then started. The spraying pump 15 extracts the spraying liquid from the storage tank 17 via the extraction pipe 16 and delivers it to the distribution box 19 via the delivery pipe 18. The distribution box 19 evenly distributes the spraying liquid into the two delivery hoses 20, allowing the two delivery hoses 20 to deliver the spraying liquid to the inside of the spraying pipe 11. This enables spraying of irregularly shaped metal objects using multiple nozzles 12. Simultaneously, the second stepper motor 7 is started, driving the drive wheel 8 to rotate. The drive wheel 8 is driven by the chain 9 and connected to the driven wheel 10 to rotate, which allows the two spray pipes 11 to swing on both sides of the irregular metal, so that the outer side of the irregular metal can be sprayed evenly. After the spraying is completed, the blower 25 and multiple electric heating tubes 27 are started. The blower 25 can transport the heat inside the heating box 26 to the air conveying ring 29 through the material conveying pipe 18, so that the air conveying ring 29 can transport the heat to the inside of the spray box 1. The continuous rotation of the irregular metal can accelerate the paint drying process.
