Description

Technical Field

[0001] This utility model relates to the field of spray painting technology, specifically a multi-nozzle synchronous spray painting device. Background Technology

[0002] Spray painting is a process that uses tools such as spray guns to atomize paint and spray it onto the surface of an object to form a uniform coating. It is widely used in many fields such as industrial production and daily life. Spray painting of car bodies can prevent metal from rusting, while spray painting of furniture surfaces can prevent wood from warping due to moisture and being infested by insects.

[0003] However, existing technologies still have the following problems:

[0004] Most existing painting equipment has low painting efficiency. Traditional painting equipment often uses a single nozzle. In large-scale workpiece painting operations, a single nozzle can only cover a small area each time. It is necessary to spray repeatedly for a long time to complete the painting of a large area, which is time-consuming and slows down the production progress. It is not suitable for mass production scenarios.

[0005] To address the aforementioned problems, the inventors proposed a multi-nozzle synchronous painting device. Utility Model Content

[0018] 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.

[0019] Example: Figure 1-4 As shown, this utility model provides a multi-nozzle synchronous painting device, including a base plate 1, a movable plate 3 slidably mounted on the upper side of the base plate 1, a bracket 5 and a paint tank 4 fixedly mounted on the upper side of the movable plate 3, and a flexible connecting pipe 41 connected to the upper surface of the paint tank 4. The flexible connecting pipe 41 has good flexibility and can be flexibly bent as the relevant components move during the operation of the device to ensure that the paint delivery is not affected. A water pump 42 is fixedly connected to one end of the flexible connecting pipe 41, and a connecting plate 43 is fixedly mounted on the other side of the water pump 42. Several nozzle components 44 are fixedly mounted on the outer side of the connecting plate 43. A cavity 45 is opened in the connecting plate 43, and the cavity 45 is connected to the water... Pump 42 is connected to nozzle 44. The paint pumped from pump 42 first enters the cavity 45 of connecting plate 43. After a short buffer and even distribution in cavity 45, it is sprayed out from each nozzle 44 with appropriate pressure and flow rate, realizing synchronous painting of multiple nozzles and greatly improving painting efficiency. After the nozzle 44 moves to the appropriate position and angle, pump 42 is started. Pump 42 draws out the paint in paint tank 4 through flexible connecting pipe 41. The paint enters the cavity 45 in connecting plate 43. Since cavity 45 is connected to several nozzles 44, the paint will be sprayed out from each nozzle 44 to synchronously paint the fixed workpiece.

[0020] A lead screw 51 is rotatably mounted inside the bracket 5. A through slot 57 is provided on the bracket 5, and the lead screw 51 is located within the through slot 57. A servo motor 52 is mounted on the inner side of the bracket 5. A protective plate is fixedly mounted on one side of the bracket 5 and is fixedly connected to the servo motor 52. The output end of the servo motor 52 passes through the bracket 5 and is fixedly connected to the lead screw 51. A moving block 53 is threaded onto the outer surface of the lead screw 51. A locking block 56 is fixedly mounted on one side of the moving block 53 and is locked inside the bracket 5. A connecting rod 54 is rotatably mounted on the outer side of the moving block 53, and a support plate 55 is rotatably mounted on one end of the connecting rod 54. One side of the lower surface of the support plate 55 is rotatably connected to the bracket 5, and the upper surface of the support plate 55 is in contact with water. Pump 42 is fixedly connected. When servo motor 52 is started, the output end of servo motor 52 drives lead screw 51 to rotate in bracket 5. Since the outer surface of lead screw 51 is threaded with moving block 53, and the locking block 56 on one side of moving block 53 is locked in bracket 5, restricting the rotation of moving block 53, when lead screw 51 rotates, moving block 53 will move linearly along lead screw 51. When moving block 53 moves, it drives support plate 55 to rotate around its rotational connection with bracket 5 through rotating connecting rod 54. The upper surface of support plate 55 is fixedly connected to water pump 42. Water pump 42 is connected to nozzle 44 through connecting plate 43, thereby realizing the angle adjustment of nozzle 44.

[0021] A guide rail 31 is fixedly provided on the upper surface of the base plate 1, and an electric slider 32 is slidably provided on the upper surface of the guide rail 31. The upper surface of the electric slider 32 is fixedly connected to the moving plate 3. By controlling the electric slider 32 to slide on the guide rail 31, and since the upper surface of the electric slider 32 is fixedly connected to the moving plate 3, the moving plate 3 will slide together with the electric slider 32 on the upper side of the base plate 1. The moving plate 3 is fixed with components such as a bracket 5 and a paint tank 4. In this way, the position of the spray nozzle 44 in the horizontal direction can be adjusted so that the spray nozzle 44 can be moved to a suitable spraying position.

[0022] A backing plate 2 is fixedly provided on one side of the upper surface of the base plate 1, and a pressure plate 22 is provided on the inner side of the backing plate 2. An electric push rod 21 is fixedly provided on the upper surface of the base plate 1, and the output end of the electric push rod 21 is fixedly connected to the pressure plate 22. There are four electric push rods 21 and four pressure plates 22, and the four electric push rods 21 and pressure plates 22 are distributed at equal intervals. When the workpiece needs to be painted, the workpiece is placed on the base plate 1 between the backing plate 2 and the pressure plate 22. The electric push rod 21 is activated, and the output end of the electric push rod 21 pushes the pressure plate 22 to move towards the backing plate 2. Since the four electric push rods 21 and pressure plates 22 are distributed at equal intervals, they can squeeze the workpiece from different positions, thereby stably fixing the workpiece on the base plate 1 and ensuring that the workpiece will not move during the painting process.

[0023] Working principle: When the workpiece needs to be painted, the workpiece is placed on the base plate 1 between the support plate 2 and the pressure plate 22. The electric push rod 21 is activated. The output end of the electric push rod 21 pushes the pressure plate 22 towards the support plate 2. Since the four electric push rods 21 and the pressure plate 22 are evenly distributed, they can squeeze the workpiece from different positions, thereby fixing the workpiece stably on the base plate 1 and ensuring that the workpiece will not move during the painting process.

[0024] By controlling the electric slider 32 to slide on the guide rail 31, since the upper surface of the electric slider 32 is fixedly connected to the moving plate 3, the moving plate 3 will slide together with the electric slider 32 on the upper side of the base plate 1. The moving plate 3 is fixed with components such as the bracket 5 and the paint box 4, so that the position of the spray nozzle 44 in the horizontal direction can be adjusted, and the spray nozzle 44 can be moved to the appropriate spraying position.

[0025] When the servo motor 52 is started, the output end of the servo motor 52 drives the lead screw 51 to rotate inside the bracket 5. Since the outer surface of the lead screw 51 is threaded with a moving block 53, and the locking block 56 on one side of the moving block 53 is locked inside the bracket 5, restricting the rotation of the moving block 53, when the lead screw 51 rotates, the moving block 53 will move linearly along the lead screw 51. When the moving block 53 moves, it drives the support plate 55 to rotate around the rotating connection point between the support plate 55 and the bracket 5 through the rotating connecting rod 54. The upper surface of the support plate 55 is fixedly connected to the water pump 42, and the water pump 42 is connected to the nozzle 44 through the connecting plate 43, thereby realizing the angle adjustment of the nozzle 44.

[0026] After the nozzle 44 is moved to the appropriate position and angle, the water pump 42 is started. The water pump 42 draws out the paint from the paint tank 4 through the flexible connecting pipe 41. The paint enters the cavity 45 in the connecting plate 43. Since the cavity 45 is connected to several nozzles 44, the paint will be sprayed out from each nozzle 44 to synchronously paint the fixed workpiece.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
