[0001] This utility model specifically relates to a multi-station sprayer for metal surfaces, belonging to the field of metal spraying technology. Background Technology

[0002] Metal surface spraying equipment is a specialized device used to apply coatings to metal surfaces, aiming to improve the corrosion resistance, wear resistance, decorative properties, or other specific functions of metal products. The device uses compressed air or other power sources to atomize the paint into tiny particles, which are then evenly sprayed onto the metal surface.

[0003] In metal surface spraying operations, the workpiece is usually positioned and fixed in the spraying fixture. After the coating is applied, the fixture is removed and the workpiece is replaced and repositioned to achieve continuous spraying operations. However, due to the limited time for non-spraying auxiliary operations such as fixture disassembly and workpiece positioning, the effective working time of the spraying equipment is reduced, thereby reducing the overall spraying efficiency.

[0017] 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.

[0018] Please see Figures 1-4As shown, a multi-station metal surface sprayer includes a base 1, a turntable 2 rotatably mounted on the top of the base 1, and a rotating motor 3 connected to the turntable 2 inside the base 1. Multiple sets of placement plates 4 are arranged around the turntable 2, each set equipped with fixing components for securing metal workpieces. A sprayer 5 and a dryer 6 are respectively located on both sides of the base 1. The base 1 serves as the supporting structure for the entire sprayer, providing a stable mounting platform. The turntable 2 rotates to move the placement plates 4 from different positions sequentially to the spraying and drying areas, enabling continuous workpiece processing. The rotating motor 3 provides the power for the rotation of the turntable 2 and ensures... The workpiece can be accurately moved to the designated position. The placement plate 4 is used to support the metal workpiece. The setting of multiple placement plates 4 provides multiple workstations, so that while spraying or drying one workpiece, the sprayed workpiece can be removed or the workpiece to be sprayed can be installed on other empty placement plates 4, thereby improving production efficiency. The fixing component is set on each placement plate 4 to fix the metal workpiece. The spraying machine 5 is used to spray the metal workpiece, and the dryer 6 is used to dry the sprayed workpiece. It accelerates the drying process of the coating by heating or other means, reduces the waiting time due to the paint not being dry, and speeds up the production process.

[0019] Work steps: Place the metal workpiece to be coated on the empty placement plate 4, and use the fixing components on the placement plate 4 to firmly fix the workpiece, ensuring that it will not move or tilt during the coating and drying process. Start the rotating motor 3 to drive the turntable 2 to rotate, moving the workpiece to be coated under the spraying machine 5. The spraying machine 5 starts working, spraying the coating material evenly on the surface of the workpiece to complete the coating construction. After the coating is completed, the turntable 2 continues to rotate under the drive of the rotating motor 3, moving the coated workpiece to the drying machine 6 area. The drying machine 6 accelerates the drying process of the coating by heating, reducing waiting time. At the same time, while the coated workpiece is drying, the workpieces on other placement plates 4 can be removed from the placement plate 4 after the coating and drying are completed, ready for the next process or packaging. Place new workpieces to be coated on the empty placement plate 4 and fix them. Then the turntable 2 continues to rotate, moving the new workpieces to be coated under the spraying machine 5, repeating the coating and drying process to achieve a continuous and efficient production process.

[0020] Furthermore, the fixing assembly includes a fixed clamping plate 7 and a movable clamping plate 8. The fixed clamping plate 7 is fixedly installed on one end of the placement plate 4, and the movable clamping plate 8 is slidably disposed on the end of the placement plate 4 away from the fixed clamping plate 7. A screw 9 is rotatably connected to one side of the movable clamping plate 8, and the other end of the screw 9 is threaded through the interior of the placement plate 4. During operation, the metal workpiece is placed between the fixed clamping plate 7 and the movable clamping plate 8. By rotating the screw 9, the clamping force between the movable clamping plate 8 and the fixed clamping plate 7 can be adjusted to accommodate metal workpieces of different materials and shapes, ensuring that the workpiece will not move or tilt during processing. The workpiece can be fixed and released simply by rotating the screw 9, making the operation simple and convenient.

[0021] Furthermore, multiple sets of receiving frames 10 are fixedly connected to the turntable 2, and the placement plate 4 is movably placed on the receiving frame 10. The four corners of the edge of the placement plate 4 and the receiving frame 10 are provided with corresponding mounting holes 11, and screws 12 are installed inside the mounting holes 11. During operation, the placement plate 4 is placed on the receiving frame 10, ensuring that the mounting holes 11 are aligned. The screws 12 are inserted into the mounting holes 11 and gradually tightened to fix the connection between the placement plate 4 and the receiving frame 10. Conversely, the screws 12 are gradually loosened to release the fixed connection between the placement plate 4 and the receiving frame 10. The placement plate 4 can then be removed from the receiving frame 10 for maintenance, replacement, or cleaning.

[0022] Furthermore, the air outlet of the dryer 6 is rotatably connected to an air jet pipe 13 via a rotary joint. Multiple air jet heads 14 are mounted on one end of the air jet pipe 13, and a gear 15 is mounted on the end of the air jet pipe 13 furthest from the air jet heads 14. An electric push rod 16 is mounted on the dryer 6, and a rack 17 is connected to the moving end of the electric push rod 16. The rack 17 and gear 15 are meshed. During operation, the electric push rod 16 extends and retracts according to a control signal, driving the rack 17 to move. The rack 17 meshes with the gear 15, converting linear motion into rotational motion, which drives the air jet pipe 13 to rotate around the rotary joint. By adjusting the extension and retraction of the electric push rod 16, the rotation angle of the air jet pipe 13 can be controlled, thereby adjusting the orientation and spray range of the air jet heads 14, ensuring that hot air evenly covers all parts of the workpiece, improving the drying effect and coating quality.

[0023] Furthermore, a paint storage tank 18 is installed on one side of the base 1. The bottom of the paint storage tank 18 is connected to the spraying machine 5 through a pump and a delivery pipe. A stirring rod 19 is rotatably installed inside the paint storage tank 18, and a stirring motor 20 connected to the stirring rod 19 is installed at the top of the paint storage tank 18. During operation, the paint is stored in the paint storage tank 18. The stirring motor 20 is started, which drives the stirring rod 19 to rotate and continuously stir the paint to prevent sedimentation or stratification. When spraying is required, the pump is started to extract the paint from the paint storage tank 18 and deliver it to the spraying machine 5 through the delivery pipe. After receiving the paint, the spraying machine 5 begins to spray the workpiece to achieve the coating construction.

[0024] Furthermore, the bottom of the base 1 is provided with a rubber pad; wherein the rubber pad is in direct contact with the ground or other supporting surface, and increases the friction between them.
