Description

Technical Field

[0001] This utility model relates to the field of spraying, and in particular to a support frame for a reciprocating spraying machine with a multi-angle adjustment mechanism. Background Technology

[0002] In the vast field of industrial production, the coating process occupies a pivotal position, not only affecting the appearance and texture of products but also profoundly influencing their durability. As a key piece of equipment in the coating process, the design of the support frame of the reciprocating sprayer directly determines the spraying effect and applicability of the equipment.

[0003] Traditional reciprocating spray painting machines often employ relatively simple mechanical structures and technical principles when dealing with complex, irregularly shaped workpieces. A common approach is to rely on light curtain detection to determine the workpiece's position, using simple mechanical transmission to move the spray gun back and forth along a preset linear trajectory to perform the spraying operation. While this method can achieve a certain degree of automation when handling regular-shaped workpieces, it has limitations in its technical principles. For example, light curtain detection can only obtain the approximate length and width dimensions of the workpiece, with an accuracy of only a few centimeters, making it difficult to accurately capture the detailed features of complex, irregularly shaped workpieces. Furthermore, in terms of the drive structure, the spray gun's degree of freedom is limited, mostly restricting it to reciprocating linear motion within a single plane.

[0004] However, when faced with complex, irregularly shaped workpieces, the drawbacks of traditional reciprocating sprayers become glaringly apparent. Due to the limitations of the spray gun's movement, dead zones easily appear at complex structures such as corners and grooves on the workpiece, resulting in insufficient paint coverage in these areas. Furthermore, the inability to precisely adjust the spray gun angle according to the workpiece's irregular contours makes it difficult to maintain a uniform coating thickness, severely impacting the overall quality and uniformity of the paint coating and limiting the equipment's adaptability to different types of workpieces. Therefore, a reciprocating sprayer support frame with a multi-angle adjustment mechanism is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a support frame for a reciprocating spraying machine with a multi-angle adjustment mechanism, which aims to improve the problems of spraying dead angles and uneven coating when the existing reciprocating spraying machine is used on complex and irregular workpieces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reciprocating spraying machine support frame with a multi-angle adjustment mechanism includes a reciprocating moving machine. A connecting plate is fixedly connected to one side of the sliding panel on the outer wall of the reciprocating moving machine. Multiple support frames are fixedly connected to one side of the connecting plate. A connecting block is fixedly connected to one side of each support frame.

[0033] 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.

[0034] Reference Figures 1-3This utility model provides an embodiment of a reciprocating spraying machine support frame with a multi-angle adjustment mechanism, including a reciprocating moving machine 1. A connecting plate 2 is fixedly connected to one side of the sliding panel on the outer wall of the reciprocating moving machine 1. The connecting plate 2 is used to stably support the subsequent multi-angle adjustment mechanism. Multiple support frames 3 are fixedly connected to one side of the connecting plate 2. The support frames 3 are used to provide solid structural support for the entire adjustment system, ensuring stability in high-frequency reciprocating motion. A connecting block 4 is fixedly connected to one side of each support frame 3. The connecting block 4 is used to accurately fix and position the motor 5. A motor 5 is fixedly connected to one side of each connecting block 4. The two motors 5 serve as the core power source, cooperating with the first connecting frame 7 and the second connecting frame 11 to perform independent rotational motion, achieving the effect of driving the spray head to deflect in multiple dimensions. The output end of one of the motors 5 is fixedly connected to the first connecting frame 7, which is used to transmit the torque of the motor 5. A rotating shaft 8 is rotatably connected inside the first connecting frame 7, which serves as the first rotating shaft. A transmission column 9 is fixedly connected to the outer wall of the first connecting frame 7. The other motor 5 outputs... A connecting bracket 2 11 is fixedly connected to the outlet end. A connecting bracket 3 12 is fixedly connected to one side of the connecting bracket 2 11. A rotating shaft 2 13 is rotatably connected inside the connecting bracket 3 12. The rotating shaft 2 13 serves as a second rotating shaft, cooperating with the rotating shaft 1 8 to perform multi-angle spatial adjustment movement, achieving the effect of spraying without dead angles. The top of the rotating shaft 2 13 is fixedly connected to the bottom of the transmission column 9. The transmission column 9, in conjunction with the rotating shaft 1 8 and the rotating shaft 2 13, performs compound rotation, achieving the effect of changing the spatial posture of the nozzle. A connecting plate 2 10 is fixedly connected to one end of the transmission column 9. The second connecting plate 10 serves as the installation platform for the execution end, and its posture directly determines the spraying angle. A buckle 21 is fixedly connected to one side of the second connecting plate 10. The buckle 21 is used to quickly clamp the spray head, realizing the function of convenient replacement. A drying component is set on one side of the buckle 21. Each rotating shaft 8 has a limit ring 6 fixedly connected to both ends. Multiple limit rings 6 fit against both sides of the connecting frame 7. The limit rings 6 are used to axially limit the rotating shaft 8 to prevent it from moving during rotation, ensuring the stability and accuracy of the rotational movement.

[0035] Reference Figure 1 , Figures 4-6The drying assembly includes a drying lamp 22, which serves as a direct heat source to emit high-intensity heat energy to dry the coating, achieving efficient drying of the workpiece surface. The drying lamp 22 is located on one side of the buckle 21, and connecting plates 23 are fixedly connected to both sides of the drying lamp 22. The connecting plates 23 serve as the mounting base for the drying assembly, integrating various parts of the quick-locking mechanism. Each connecting plate 23 has a fixing ring 19 fixedly connected inside, which is used to fix one end of the spring 18 and provide sliding guidance for the connecting post 15, ensuring the accuracy of its linear movement. Each fixing ring 19 has a connecting post 15 slidably connected to its inner wall. Multiple connecting posts 15 extend one end into the interior of the connecting plate 10, and each connecting post 15 has a baffle 16 fixedly connected to one end. The baffle 16 cooperates with the pushing, pulling, and rotating of the connecting post 15 to complete the locking action, and is the key actuator for achieving mechanical locking. Multiple baffles 16 engage with the internal grooves of the connecting plate 10, achieving a firm fixation of the entire drying assembly to the connecting plate 10. On plate 2 10, each connecting post 15 has a handle 14 fixedly connected to its other end. The handle 14 provides a convenient human-machine interface. The operator can complete the complex locking and unlocking process by pressing and rotating the handle 14. Each connecting post 15 has a rotating ring 20 fixedly connected to its outer wall. Each rotating ring 20 has a sliding ring 17 rotatably connected to its outer wall. The sliding ring 17 rotates relative to the rotating ring 20, achieving the effect of decoupling the rotational motion of the connecting post 15 from the tensioning motion of the spring 18, avoiding torsional damage to the spring 18 when rotating the handle 14. The outer wall of each sliding ring 17 is slidably connected to the inner wall of connecting plate 3 23. Each connecting post 15 has a spring 18 on its outer wall. The spring 18 is used to store and release elastic potential energy. After releasing the handle 14, its rebound force automatically drives the baffle 16 to lock into the groove, achieving a quick self-locking effect. One end of each spring 18 is fixedly connected to the outer wall of the fixed ring 19, and the other end of each spring 18 is fixedly connected to the outer wall of the sliding ring 17.

[0036] Working principle: During spraying, the spray head is first securely installed on one side of the connecting plate 10 using clip 21. Then, depending on the complex shape of the workpiece and the spraying requirements, two motors 5 can be started independently or in concert. When one motor 5 is working, its output drives the connecting frame 7 to rotate. The connecting frame 7 then drives the transmission column 9 and the connecting plate 10 fixed on it to pitch or yaw about the rotating shaft 13. When the other motor 5 is working, its output drives the connecting frame 11 and the connected connecting frame 12, thereby driving the entire transmission column 9 to move about the rotating shaft 13. The center rotates in another dimension. Through the combined control of two motors 5, the multi-degree-of-freedom spatial posture adjustment of the connecting plate 2 10 (i.e., the spray head) can be achieved, thus realizing precise multi-dimensional adjustment of the paint spraying angle. This solves the problems of spraying dead angles and uneven coating thickness that traditional reciprocating sprayers easily produce when dealing with complex workpieces. It enhances the automation level of the spraying operation and the adaptability to different products, ultimately improving the overall quality and uniformity of the paint coating. After the spraying operation is completed, the connecting plate 3 23 with the drying lamp 22 is moved to the installation position of the connecting plate 2 10. Insert the baffle 16 at the end of the connecting post 15 into the preset internal slot of the connecting plate 10. Then press the handle 14 inward. The connecting post 15 will move inward and stretch the spring 18 through the slip ring 17, storing elastic potential energy. Then rotate the handle 14 ninety degrees, causing the connecting post 15 and the baffle 16 to rotate synchronously. During this process, since the rotating ring 20 and the slip ring 17 are rotatably connected, the rotation of the connecting post 15 will not have a torsional effect on the spring 18, ensuring the stability of the mechanism. Finally, release the handle 14. Under the rebound force of the spring 18, the slip ring 17 will push the connecting post 15 to rotate. The retraction of the connecting column 15 and the baffle 16 allows the rotated baffle 16 to be firmly inserted into the groove inside the connecting plate 10, thereby achieving a quick and reliable connection and fixation between the drying component and the spraying body. This achieves a close connection and seamless switching between the spraying and drying processes, solving the problem of the large amount of time consumed by the transfer of workpieces between different workstations in the traditional production process, as well as the problem of the wet paint surface being easily contaminated during the transfer process, leading to an increased product defect rate. This enhances the continuity and overall efficiency of the production process and ensures the smoothness and high quality of the final product surface coating.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
