Description

Technical Field

[0001] This utility model relates to the field of surface treatment equipment technology, specifically a multi-angle rotating atomizing spraying system. Background Technology

[0002] Rotary atomizing spraying systems are widely used in surface treatment processes in industries such as automotive manufacturing, electronic equipment, aerospace, and hardware products. The principle is to use the centrifugal force generated by a high-speed rotating disc or wheel to throw the liquid material out to form droplets. The spray cup rotation speed is typically greater than 20,000 rpm, enabling linear, lamellar, and turbine-like multi-plate atomization.

[0003] A search revealed a rotary atomizing coating apparatus, such as the one disclosed in patent CN115350827A. This apparatus has a bell-shaped cup mounted on a rotary drive shaft. The side surface of the bell-shaped cup is formed parallel to the rotary drive shaft. A first groove, a second groove, and a third groove are recessed towards the outer surface of the side surface on its inner surface. A first through hole, a second through hole, and a third through hole are provided in the first groove, second groove, and third groove. These through holes pass through the inner and outer surfaces, and are used to spray coating material outwards from the bell-shaped cup.

[0004] The bell cup of this device produces a large number of large paint particles during the spraying process, resulting in uneven dispersion, poor atomization and spraying effect. Furthermore, the spraying angle of the bell cup cannot be adjusted, making it inconvenient for spraying curved surfaces (such as the housing of a car rearview mirror). To address these issues, we propose a multi-angle rotating atomization spraying system. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. By using a support assembly to firmly clamp and limit the inner wall of the part to be painted, it is ensured that the part will not shift or shake during rotation, thereby improving the accuracy and uniformity of the painting. The design of the support assembly allows it to adapt to parts of different shapes and sizes, enhancing the versatility and practicality of the system. In addition, the firm clamping and limiting can effectively prevent paint splashing during the painting process, keep the working environment clean, and further improve painting efficiency and quality. 2. The angle adjustment mechanism enables multi-angle adjustment of the spraying angle, which not only improves the flexibility of spraying but also greatly meets the spraying needs of complex workpiece surfaces. By precisely controlling the angle adjustment mechanism, operators can easily adjust the position and angle of the spray nozzle according to the specific shape and requirements of the parts being sprayed, ensuring that the paint can evenly cover every corner of the parts and avoid spraying dead spots. In addition, the smooth operation and stable performance of the angle adjustment mechanism ensure the continuity and efficiency of the spraying process, further improving the overall spraying efficiency and coating quality. 3. The direct-drive motor drives the spraying component. The two baffles on the spraying component effectively reduce the generation of large paint particles. Through the discharge ports, the paint is evenly transferred and dispersed, forming mist-like particles, thus improving atomization and spraying effect. At the same time, the bell-shaped cup diffuser design allows the paint to spread more evenly when sprayed, further improving the uniformity and quality of spraying. In addition, the use of the direct-drive motor reduces energy loss during transmission, improves spraying efficiency, and also makes the spraying process more stable and reliable.

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. Example 1

[0020] Reference Figure 1-3This is the first embodiment of the present invention. This embodiment provides a multi-angle rotary atomizing spraying system, including a spraying box 1.

The waterproof stepper motor 11 is fixedly installed on a support plate 10. The two ends of the support plate 10 are respectively fixedly connected to the inner walls of the bottom two sides of the spraying chamber 3. Example 2

[0021] Reference Figure 1-16 This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, the support component 9 includes a fixed platform 91, an adjusting cap 92, a positioning claw 93, a transmission cavity 94, a transmission connecting rod 95, an active connecting rod 96, a slide 97, a bidirectional screw 98, and a transmission shaft 99. The bottom center of the fixed platform 91 is fixedly connected to the end of the output shaft of the waterproof stepper motor 11. Multiple transmission cavities 94 are hollowly provided on both sides of the fixed platform 91. A bidirectional screw 98 is rotatably installed in each transmission cavity 94.

[0022] Furthermore, the bidirectional screws 98 on the same side are coaxially arranged and fixedly connected to each other. One end of each bidirectional screw 98 on the same side is fixedly connected to an adjusting cap 92. The adjusting cap 92 is located outside the fixed platform 91. The positioning claws 93 located at the transmission cavity 94 are symmetrically arranged in pairs, that is, the positioning claws 93 at one transmission cavity 94 position form a group, and there are four positioning claws 93 in a group. The end of the positioning claw 93 away from the transmission shaft 99 is fixedly connected to an anti-slip rubber block. When the positioning claw 93 contacts the inner wall of the workpiece, it increases the friction at the contact position, thereby effectively preventing the workpiece from sliding or shifting during rotation, and further improving the accuracy and stability of spraying. In addition, the design of the anti-slip rubber block also has a certain buffering effect, which can reduce the hard friction between the positioning claw 93 and the inner wall of the workpiece, protect the surface of the workpiece from damage, and extend the service life of the workpiece.

[0023] Specifically, the drive module 4 includes a longitudinal linear motor 41 and a transverse linear motor 42.

This design allows the electric telescopic rod 5 to move freely in a two-dimensional plane within the spray chamber 3, thereby driving the sprayed part 8 to precisely spray different positions of the workpiece. Through the preset program of the PLC controller 2, the movement path of the electric telescopic rod 5 can be precisely controlled to ensure the uniformity and coverage of the spraying.

[0024] Specifically, the angle adjustment mechanism 6 includes a housing 61, a first small motor 62, a second small motor 63, a rotation adjustment component 64, an angle adjustment component 65, and a mounting rod 66. One end of the housing 61 is fixedly connected to the drive end of the electric telescopic rod 5. The center of the inner wall of the housing 61 is fixedly connected to the first small motor 62. The output shaft of the first small motor 62 is fixedly connected to one end of the rotation adjustment component 64. The other end of the rotation adjustment component 64 is fixedly connected to one end of the mounting rod 66. A direct drive motor 7 is fixedly installed on the other end of the mounting rod 66. The rotation adjustment component 64 is connected to the angle adjustment component 65. The angle adjustment component 65 is fixedly connected to the output shaft of the second small motor 63. The second small motor 63 is fixedly installed on one side of the inner wall of the housing 61. The other end of the housing 61 is open, and a piano-type sealing plate 60 is fixedly connected to the inner wall of the opening.

[0025] Furthermore, the rotation adjustment assembly 64 includes a rotating shaft 641, a support ring 642, a transmission shaft 643, and an L-shaped plate 644. One end of the rotating shaft 641 is fixedly connected to the output shaft of the small motor 62, and the other end of the rotating shaft 641 is fixedly connected to the outer wall of the support ring 642. The transmission shaft 643 is rotatably sleeved inside the support ring 642.

[0026] Furthermore, the angle adjustment assembly 65 includes a lead screw 651, a transmission block 652, a support base 653, an adjusting ring 654, a toggle ball 655, a connecting rod 656, and a support slide rod 657. One end of the lead screw 651 is fixedly connected to the output shaft of the small motor 63. The lead screw 651 is connected to the transmission block 652 via a threaded structure. The transmission block 652 is fixedly connected to one side of the outer wall of the adjusting ring 654. An annular groove is formed inside the adjusting ring 654, and the toggle ball 655 is engaged inside the annular groove. The toggle ball 655 is fixedly connected to... One end of the connecting rod 656 and the other end of the connecting rod 656 are fixedly connected to the outer wall of one side of the transmission shaft 643. The outer wall of the adjusting ring 654 is fixedly connected to two support sliders, and the support sliders are slidably connected to the support slide rod 657. One end of the support slide rod 657 is fixedly connected to the inner wall of the housing 61. The ends of the support slide rod 657 and the lead screw 651 are rotatably connected to the support seats 653. The support seats 653 are fixedly connected to the inner side wall of the housing 61. The axis of the adjusting ring 654 and the axis of the support ring 642 are perpendicular to each other.

[0027] In the angle adjustment mechanism 6, the design of the rotation adjustment component 64 allows the mounting rod 66 to rotate around the output shaft of the small motor 62, thereby achieving angle adjustment of the sprayed part 8 on the horizontal plane. At the same time, the setting of the angle adjustment component 65 allows the transmission block 652 to drive the adjustment ring 654 to move linearly up and down around the support slide rod 657, and then drive the transmission shaft 643 to rotate through the connecting rod 656, thereby achieving angle adjustment of the sprayed part 8 on the vertical plane. The precise control of the small motor 63 ensures the accuracy and stability of the angle adjustment.

[0028] Specifically, a mounting base 71 is fixedly connected to one side of the direct drive motor 7, and a feed pipe 72 is fixedly connected to the mounting base 71. The spraying part 8 includes an inner turntable 81, a middle turntable 82, and a bell-shaped cup 83. The inner turntable 81 is sleeved inside the middle turntable 82, and the bell-shaped cup 83 is fixedly connected to the outer wall of the middle turntable 82. The inner turntable 81 and the middle turntable 82 are fixedly connected to the output shaft end of the direct drive motor 7 with screws.

[0029] Furthermore, the inner turntable 81 has a material cavity 811, and the bottom of the material cavity 811 has multiple circumferentially distributed discharge ports 813.

[0030] Furthermore, the top of the turntable 82 has an opening, and the bottom center of the turntable 82 has a mounting hole 821. The bottom of the turntable 82 has multiple circumferentially distributed positioning holes 822, which are inserted into and fitted with positioning blocks 814. An inner turntable 81 is nested inside the turntable 82, and a gap cavity 823 is provided between the inner turntable 81 and the turntable 82. Multiple circumferentially distributed discharge ports 824 are located in the middle of the turntable 82, inside the bell-shaped cup 83. The inner edge of the bell-shaped cup 83, away from the turntable 82, has a diffuser 831, which is a concave curved surface. A retaining rim 825 extends from the opening of the turntable 82. The inner wall of the bell-shaped cup 83 is a convex curved surface. The increased centrifugal force of the liquid coating increases its movement speed, which helps to form a thin film. The diffuser 831 further increases the component of the centrifugal force perpendicular to the concave curved surface, allowing the coating to cover the inner wall of the bell cup 83 more evenly, thus improving atomization and spraying effects. In addition, the precise fit between the inner turntable 81 and the middle turntable 82, as well as the insertion design of the positioning block 814 and the positioning hole 822, not only improve the overall structural stability of the sprayed part 8, but also ensure the smoothness and uniformity of the coating during transmission, providing a solid foundation for high-quality spraying operations. It also facilitates quick assembly and disassembly of the inner turntable 81 and the middle turntable 82.

[0031] In summary, the multi-angle rotary atomizing spraying system provided by this utility model, through the integrated application of limit design, angle adjustment mechanism, and direct drive motor, achieves precise control over spraying angle, speed, and area. This not only improves spraying efficiency and coating quality but also meets the spraying requirements of complex workpiece surfaces. Furthermore, this spraying system boasts advantages such as simple structure, convenient operation, and low maintenance costs, demonstrating broad application prospects and market value.

[0032] The working principle and process are as follows: The spraying box 1 is hinged with a door, and a transparent observation window is provided at the door for easy viewing of the internal spraying process. The workpiece to be sprayed (such as the housing of a car rearview mirror) is placed on the fixed platform 91 of the support assembly 9, and the workpiece is located outside the positioning claw 93. The adjusting cap 92 is operated manually with tools (such as wrenches, sockets, etc.). The adjusting cap 92 drives the bidirectional screw 98 to rotate. The bidirectional screw 98 drives the slide 97 to slide in the transmission cavity 94. The slide 97 drives the transmission shaft 99 and the positioning claw 93 to rotate through the active connecting rod 96 and the transmission connecting rod 95. The positioning claw 93 swings towards the inner wall of the workpiece to achieve clamping and limiting of the workpiece, ensuring that the workpiece will not shift or shake during rotation. The process is controlled by a PLC. Device 2 controls the waterproof stepper motor 11 to start, which drives the fixed platform 91 to rotate, thereby rotating the workpiece. Then, PLC controller 2 controls the drive module 4 to start, causing the longitudinal linear motor 41 and the transverse linear motor 42 to work together, moving the electric telescopic rod 5 and the angle adjustment mechanism 6 within the spray chamber 3 to adjust the spraying position. Next, PLC controller 2 controls the small motors 62 and 63 to start. Small motor 62 drives the rotation adjustment component 64 and the mounting rod 66 to rotate, thereby rotating the direct drive motor 7 and the workpiece 8. Small motor 63 drives the angle adjustment component 65 to adjust the spraying angle, meeting the spraying requirements of complex workpiece surfaces. After the direct drive motor 7 starts, the paint... The coating enters the feed pipe 72 via the connecting pipe, and finally enters the material cavity 811 of the spraying part 8. Guided by the baffle 815, the coating is evenly distributed within the material cavity 811. Then, under centrifugal force, it passes through the outlet 813 and is thrown into the gap cavity 823. After passing through the outlet 813, the coating forms several small particles distributed within the gap cavity 823. Simultaneously, due to centrifugal force, some coating may be thrown directly out of the material cavity 811 without passing through the outlet 813, resulting in large particles. At this point, the baffle 815 on the inner turntable 81 prevents the coating from being directly thrown out under centrifugal force, thus effectively reducing the formation of large particles. The coating then enters the gap cavity 823. After 3, under the action of centrifugal force, the coating enters the bell-shaped cup 83 through the discharge port 2 824. After passing through the discharge port 2 824, it is evenly formed into several mist-like particles and enters the bell-shaped cup 83. At the same time, the setting of the baffle 2 825 prevents the coating from being thrown out directly without passing through the discharge port 2 824. Under the action of the baffle 2 825 and the diffuser 831, the coating is evenly atomized and sprayed onto the surface of the workpiece. During the entire spraying process, the action of each component is precisely controlled by the PLC controller 2 to achieve a high-efficiency and uniform spraying effect. In summary, the multi-angle rotary atomizing spraying system provided by this utility model achieves high-precision and high-efficiency spraying of the inner wall of the workpiece through the synergistic action of the support component 9, the drive module 4 and the angle adjustment mechanism 6.This system not only boasts wide applicability, adapting to workpieces of varying shapes and sizes, but also delivers uniform and high-quality coating, significantly improving production efficiency and product quality. Furthermore, its rational structural design, ease of operation, and convenient maintenance bring new technological breakthroughs and development opportunities to the coating industry.
