Description

Technical Field

[0001] This utility model relates to the field of spray coating technology, specifically to a swing-type automatic spray coating device for spray coating. Background Technology

[0002] An automatic oscillating spraying device for spraying is an advanced spraying equipment. It has an automatically oscillating nozzle and achieves automated operation through an automatic control unit and sensor system. When the workpiece is transported to the spraying area, the nozzle, driven by the oscillating mechanism, oscillates left and right or up and down according to set parameters, while uniformly spraying paint onto the workpiece surface. The research and development of advanced workpiece surface spraying technology is dedicated to exploring innovative spraying processes, materials, and methods, aiming to improve spraying quality, efficiency, and environmental friendliness, and meet the high requirements of different workpieces for surface performance and appearance.

[0003] A search revealed that Chinese patent CN219051795U discloses a swing-type automatic spraying device for spraying. The patent describes a technical solution that uses a transmission mechanism, connecting rod, swing rod, rotating shaft, and stabilizing component to enable the transmission mechanism to drive the swing rod to swing back and forth continuously via the connecting rod. The swing rod then drives the spray gun to swing continuously, thereby increasing the area sprayed by the spray gun. The stabilizing component makes the swing rod more stable during the swing.

[0004] In this solution, although the spraying area can be increased by reciprocating swing, the spray gun in the device is at a vertical downward angle. Therefore, spraying can only be done in one vertical direction, which means that some tilted parts of the part being sprayed cannot be reached. As a result, it is necessary to use another spray gun for spraying, which greatly reduces the work efficiency. In order to solve this technical problem, this utility model proposes a swing-type automatic spraying device for spraying. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In this solution, although the spraying area can be increased by reciprocating swing, the spray gun in the device is at a vertical downward angle. Therefore, spraying can only be done in one vertical direction, which means that some tilted parts of the part being sprayed cannot be reached. As a result, it is necessary to use another spray gun for spraying, which greatly reduces the work efficiency. In order to solve this technical problem, this utility model proposes a swing-type automatic spraying device for spraying.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a swing-type automatic spraying device for spraying, comprising a connecting frame, a horizontal plate fixedly connected to the bottom of the connecting frame, rotating columns rotatably connected to both ends of the horizontal plate, a spray gun fixedly connected to the other end of the rotating columns, a spring fixedly connected to the inner side wall of the bottom of the spray gun, the other end of the spring fixedly connected to the bottom wall of the horizontal plate, a pair of fixing plates fixedly connected to the outer wall above the connecting frame, a reciprocating motor II fixedly connected to the outer wall of the fixing plates, and a feeding roller fixedly connected to the output shaft of the reciprocating motor II, a rope wound around the outer wall of the feeding roller, a connecting ring fixedly connected to the other end of the rope, connecting ropes fixedly connected to both sides of the connecting ring, and the other end of the connecting rope fixedly connected to the spray gun.

[0008] Preferably, a fixing frame is provided on the outside of the connecting frame, a reciprocating motor is fixedly connected to the upper outer wall of the fixing frame, a threaded rod is fixedly connected to the output end of the reciprocating motor, a connecting block is threadedly connected to the outer wall of the threaded rod, an electric push rod is fixedly connected to the bottom of the connecting block, and a connecting frame is fixedly connected to the output end of the electric push rod.

[0009] Preferably, a pair of diagonal rods are fixedly connected to both sides of the lower part of the connecting frame, and a pulley is rotatably connected to the other end of each diagonal rod, and the connecting rope slides on the pulley.

[0010] Preferably, a pulley two is rotatably connected in the middle of the connecting frame, and the rope is slidably connected in the pulley two.

[0011] Preferably, limit rods are fixedly connected to both sides of the upper part of the connecting frame, and limit blocks are fixedly connected to both sides of the connecting block. The limit rods are slidably connected in the limit blocks, and a sliding groove is provided on the upper part of the fixed frame, and the limit blocks are slidably connected in the sliding groove.

[0012] Preferably, each of the spray guns is provided with a material conveying pipe at its top.

[0013] This utility model provides a swing-type automatic spraying device for spray coating. It has the following beneficial effects:

[0014] (1) The reciprocating motor 2 on the fixed plate starts and drives the unwinding roller to rotate and wind up the rope. The rope is positioned by the pulley 2 on the connecting frame, which pulls the connecting ring to move up. The connecting ring drives one end of the connecting rope to move up. The connecting rope is limited by the pulley 1 on the inclined rod, which pulls the spray gun to rotate around the rotating column on the horizontal plate, so that the bottom end of the spray gun is outward and stretches the spring. When the reciprocating motor 2 rotates in the opposite direction, the rope is released, the connecting ring moves down, and the spring rebounds and pulls the bottom end of the spray gun inward. This combination solves the problem of existing spraying devices. The traditional device has a fixed or inconvenient spray gun angle, which cannot accurately control the spraying direction, resulting in uneven spraying and low efficiency. This design can flexibly adjust the spray gun angle. Through the coordination of various components, the linkage of the rope and the connecting rope and the reset function of the spring are used to achieve precise adjustment of the spray gun angle, thereby improving the spraying accuracy and efficiency.

[0015] (2) Once the reciprocating motor on the fixed frame is started, it drives the threaded rod to rotate back and forth, causing the connecting block to move back and forth. The connecting block drives the electric push rod to move, and at the same time, the electric push rod is started to push the connecting frame and the spray gun to move up and down. The two work together to increase the spraying range of the spray gun. When the connecting frame moves, its limiting rod slides in the limiting block to ensure stability. When the connecting block moves, the limiting block slides in the groove to ensure stability and reliability. This cooperation solves the problem of existing spraying devices. Traditional devices often can only spray in a fixed area or have a limited adjustment range, which makes it difficult to spray large areas or complex shapes of objects evenly and comprehensively. This design, through the cooperation of various components, uses the reciprocating motor, threaded rod, electric push rod, etc. to realize the flexible movement of the spray gun in two dimensions, expands the spraying range, and improves the spraying quality and efficiency.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] Example 1: An automatic oscillating spraying device for spraying processes includes a connecting frame 7. A horizontal plate 10 is fixedly connected to the bottom of the connecting frame 7. Rotating columns 11 are rotatably connected to both ends of the horizontal plate 10. A spray gun 12 is fixedly connected to the other end of the rotating column 11. A spring 13 is fixedly connected to the inner side wall of the bottom of the spray gun 12. The other end of the spring 13 is fixedly connected to the lower wall of the horizontal plate 10. A pair of fixing plates 16 are fixedly connected to the outer wall above the connecting frame 7. A reciprocating motor 18 is fixedly connected to the outer side wall of the fixing plates 16. The output shaft of the reciprocating motor 18 is... A wire feeding roller 17 is fixedly connected, and a rope 19 is wound around the outer wall of the wire feeding roller 17. A connecting ring 21 is fixedly connected to the other end of the rope 19. A connecting rope 22 is fixedly connected to both sides of the connecting ring 21. The other end of the connecting rope 22 is fixedly connected to the spray gun 12. A pair of diagonal rods 14 are fixedly connected to both sides below the connecting frame 7. The other end of the diagonal rods 14 is rotatably connected to a pulley 15, and the connecting rope 22 slides on the pulley 15. A pulley 20 is rotatably connected in the middle of the connecting frame 7, and the rope 19 slides inside the pulley 20.

[0024] The reciprocating motor 18, mounted on the external fixing plate 16 of the connecting frame 7, is started. After the reciprocating motor 18 starts running, it generates power, driving the pay-off roller 17 to rotate. The rotation of the pay-off roller 17 winds up the rope 19. During the winding process, the pulley 20 on the connecting frame 7 positions the rope 19, ensuring it moves along the predetermined path. As the rope 19 winds up, it drives the connecting ring 21 to move upwards. When the connecting ring 21 moves upwards, one end of the connecting rope 22 on both sides also moves upwards. During the movement of the connecting rope 22, the pulley 15 on the inclined rod 14 limits its movement, ensuring stable movement. Pulled by the connecting rope 22, the spray gun 12 connected to its other end rotates. Since the spray gun 12 is positioned on the horizontal plate 10 by the rotating column 11, it rotates at fixed points around the rotating column 11 at both ends of the horizontal plate 10. During this process, the bottom of the spray gun 12 pulls on the spring 13 at its base. Due to the upward pull of the connecting rope 22, the bottom of the spray gun 12 rotates outward, thereby adjusting the angle. When the reciprocating motor 18 rotates in the opposite direction, the rope 19 is released, and the connecting ring 21 moves downward under the influence of gravity and other factors, releasing the connecting rope 22 as well. At this time, the spring 13 uses its own rebound force to pull the bottom of the spray gun 12 inward. Through the close cooperation between these components, the angle of the spray gun 12 can be effectively adjusted, thus allowing for more precise control of the spraying direction during spraying operations.

[0025] Example 2: The difference between this example and Example 1 is that a fixed frame 1 is provided on the outside of the connecting frame 7. A reciprocating motor 2 is fixedly connected to the upper outer wall of the fixed frame 1. A threaded rod 3 is fixedly connected to the output end of the reciprocating motor 2. A connecting block 4 is threadedly connected to the outer wall of the threaded rod 3. An electric push rod 6 is fixedly connected to the bottom of the connecting block 4. The connecting frame 7 is fixedly connected to the output end of the electric push rod 6. Limiting rods 8 are fixedly connected to both sides of the upper part of the connecting frame 7. Limiting blocks 5 are fixedly connected to both sides of the connecting block 4. The limiting rods 8 are slidably connected to the limiting blocks 5. At the same time, a sliding groove 9 is opened on the upper part of the fixed frame 1. The limiting blocks 5 are slidably connected to the sliding groove 9. A material conveying pipe 23 is provided at the top of each spray gun 12.

[0026] The reciprocating motor 2 installed on top of the fixed frame 1 is started. After the reciprocating motor 2 starts working, it generates power, which drives the threaded rod 3 to reciprocate. When the threaded rod 3 reciprocates, it drives the connecting block 4 to move left and right. While the connecting block 4 moves left and right, it is connected to the electric push rod 6, so it drives the electric push rod 6 to move together. With the activation of the electric push rod 6, the electric push rod 6 generates an upward or downward thrust, pushing the connecting frame 7 and the spray gun 12 installed at the bottom of the connecting frame 7 to move up and down. By combining this up and down movement with the left and right movement driven by the connecting block 4, the spray gun 12 can cover a larger area, thus effectively increasing the area sprayed by the spray gun. During the movement of the connecting frame 7, the stability of the movement is ensured by the cooperation of the limiting rod 8 and the limiting block 5. The limiting rod 8 slides within the limiting block 5, which can prevent unnecessary shaking or deviation of the connecting frame 7 during movement. Similarly, when the connecting block 4 moves, the limiting block 5 slides within the groove 9. This design ensures that the connecting block 4 moves more stably and reliably, further guaranteeing the stability and accuracy of the entire spray gun moving system.

[0027] Working principle: When the operator needs to use the spraying device, firstly, the reciprocating motor 18 on the external fixing plate 16 of the connecting frame 7 is started. Under the action of the reciprocating motor 18, the unwinding roller 17 is rotated, thereby winding the rope 19. During winding, the rope 19 is positioned by the pulley 20 on the connecting frame 7, and the rope 19 will drive the connecting ring 21 to move upward. When the connecting ring 21 moves upward, it will drive one end of the connecting rope 22 on both sides to move upward. When the connecting rope 22 moves, it is limited by the pulley 15 on the inclined rod 14. At this time, the connecting rope 22 will pull the spray gun 12 on the other end to rotate. The spray gun 12 is positioned on the horizontal plate 10 by the rotating column 11. Therefore, the spray gun 12 rotates at a fixed point at both ends of the horizontal plate 10 by the rotating column 11, and will pull the spring 13 at the bottom end. The upward pull of the connecting rope 22 causes the bottom end of the spray gun 12 to rotate outward for adjustment. When the 8-axis rotates in the reverse direction, the rope 19 is loosened and the connecting ring 21 moves down, thereby loosening the connecting rope 22. At this time, the spring 13 will pull the bottom of the spray gun 12 to rotate inward through its rebound. Through their cooperation, the angle adjustment effect is achieved, making the spraying more precise. After the angle adjustment is completed, the reciprocating motor 2 above the fixed frame 1 is started. Under the action of the reciprocating motor 2, the threaded rod 3 is driven to rotate reciprocally. When the threaded rod 3 rotates reciprocally, it will drive the connecting block 4 to move left and right. When the connecting block 4 moves, it will drive the electric push rod 6 to move. With the start of the electric push rod 6, the connecting frame 7 and the bottom spray gun 12 will move up and down, thereby increasing the spraying area of ​​the spray gun. When the connecting frame 7 moves, it is limited by the limiting rod 8 within the limiting block 5. When the connecting block 4 moves, it is limited by the limiting block 5 within the sliding groove 9, thereby ensuring more stable and reliable movement.
