Description

Technical Field

[0001] The invention relates to the technical field of profile spraying, and more specifically to a multi-angle spraying device for producing aluminum profiles. Background Art

[0002] As a key basic material for modern industrial manufacturing, aluminum profiles are widely used in building curtain walls, rail transit, new energy equipment, consumer electronics and other fields due to their lightweight, high strength and easy processing characteristics. As industrial design continues to increase the requirements for structural functionality, the cross-sectional shape of aluminum profiles has become increasingly complex, and designs such as multi-cavity structures, special-shaped channels, and asymmetric bends have become typical features of high-end applications. In this context, surface spraying, as a core process to improve the weather resistance, corrosion resistance and decorative effects of aluminum profiles, has become increasingly prominent in terms of technical bottlenecks.

[0003] At present, aluminum profile spraying production lines generally adopt an operation mode that combines a fixed spray gun array with a conveying system, which exposes multiple technical defects in actual applications. First, the traditional spray gun group is limited by the fixed installation angle and can only provide basic coverage of the outer surface of the profile. For profiles with high cross-sectional geometric complexity (such as profiles with internal grooves, multi-directional reinforcement ribs or concealed cavity structures), the spray material flow is difficult to effectively reach the side walls and back areas with an inclination angle of more than 45°, forming a spraying blind area. According to statistics, after such complex cross-section profiles are sprayed in traditional equipment, the coating thickness uniformity deviation generally exceeds ±20μm, resulting in about 18% to 25% of the products requiring secondary spraying, which significantly increases production costs and energy consumption.

[0004] In addition, the paint utilization rate of traditional spraying processes is generally low. Since the deposition efficiency of atomized paint from a fixed spray gun decreases significantly when spraying non-vertically, when the spray gun is tilted at an angle of more than 55°, the effective adhesion rate of the paint drops sharply from 82% in the vertical state to 48%, and a large amount of paint escapes into the air to form pollution. In open spray workshops, the comprehensive utilization rate of paint is usually less than 60%, which not only increases the cost of raw materials, but also causes VOC emissions to exceed the environmental protection standard limit by 2-3 times. Although some companies have tried to compensate for the lack of coverage by increasing the number of spray guns, this has further aggravated paint waste and equipment energy consumption, forming a vicious circle. In view of this, we propose a multi-angle spraying device for aluminum profile production. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention improves the existing spraying device for aluminum profile production by arranging a vertical reciprocating mechanism at the moving end of the horizontal moving mechanism, arranging a spraying frame at the moving end of the vertical reciprocating mechanism, arranging a paint nozzle on the spraying frame, and installing a dual-state spraying mechanism at the output end of the paint nozzle. The linkage adjustment component of the dual-state spraying mechanism is driven by the angle adjustment mechanism to drive the synchronous driving component and the rotating component to adjust synchronously, so that the dead-angle spraying component and the opening and closing component form a front diffusion spraying state and a reverse dead-angle spraying state, and realize the switching of two spraying modes. The conventional surface adopts front diffusion spraying, and the atomized paint forms a fan-shaped coverage; when the inner groove or cavity structure is detected, the rotating component is driven to rotate, and the opening and closing component closes the guide channel, so that the dead-angle spraying component is protruded from the inside of the profile, and the dead-angle high-pressure spraying is performed, which significantly improves the spraying efficiency and environmental protection of high-precision aluminum profiles.

[0019] 2. In the present invention, the linkage adjustment component is driven by the angle adjustment mechanism to drive the linkage adjustment component to rotate, and the linkage adjustment component drives the synchronous drive component to rotate on the rotating groove. The synchronous drive component synchronously drives a plurality of racks and movable nozzles to move on the slide grooves of the load-bearing outer ring and the load-bearing inner ring to achieve synchronous inward retraction or synchronous outward expansion. When the long holes opened on the movable nozzle are all retracted into the load-bearing outer ring, the inner wall of the load-bearing outer ring blocks the long holes, and the paint enters the inner wall of the load-bearing inner ring through the paint nozzle, enters the inner wall of the linkage adjustment component, and enters the inner wall of the rotating component. At this time, the opening and closing component is in the open state. Finally, the fan-shaped diffusion spraying is achieved through the spray diffusion member to expand its spraying area and improve the spraying efficiency.

[0020] 3. In the present invention, the linkage adjustment component is driven by the angle adjustment mechanism to drive the linkage adjustment component to rotate, the linkage adjustment component drives the synchronous drive component to rotate on the rotating groove, and the synchronous drive component synchronously drives a plurality of racks and movable nozzles to move on the slide grooves of the load-bearing outer ring and the load-bearing inner ring to achieve synchronous inward retraction or synchronous outward expansion. When the long holes opened on the movable nozzle are all expanded outward to protrude from the load-bearing outer ring, the opening and closing component is in a closed state at this time, and the paint enters the inner wall of the load-bearing inner ring through the paint nozzle, is injected into the movable nozzle through the feed port, and then is sprayed out through the long hole of the movable nozzle, so as to achieve uniform spraying of the dead corners and corners of the inner cavity of the aluminum profile, form a multi-angle radial spray path, increase the blind spot coverage area, and significantly optimize the spraying process.

[0021] 4. In the present invention, the outer gear ring is driven to rotate by the engagement of the angle adjustment mechanism, and the outer gear ring drives the connecting ring at one end to rotate. The rotation of the connecting ring drives the first inner gear ring fixedly connected to it to rotate on the pulley of the rotating groove. The first inner gear ring engages to drive several gears to rotate, and the rotation and engagement of the gears drive the rack and the movable nozzle at the other end to slide in the slide groove; the outer gear ring also engages with the rotating component at the other end to drive the opening and closing component to realize opening and closing, and the overall switching of the two states is realized through a driving structure. The present invention realizes a dual-state switching mechanism of multi-component linkage through a single driving source, which solves the problems of difficult coordination of multiple actuators and response lag in traditional spraying equipment, and also has the advantages of saving space layout and reducing energy consumption.

[0022] 5. In the present invention, the outer gear ring is driven to rotate by the engagement of the angle adjustment mechanism, and the outer gear ring is engaged to drive the second inner gear ring to rotate, and the second inner gear ring drives the rotating ring and the straight groove to rotate. The rotation of the straight groove drives the sliding block movably inserted therein to drive the opening and closing blades to deflect. Since the limit rod at the other end of the opening and closing blade is movably inserted in the sliding hole of the fixed ring, a plurality of opening and closing blades rotate synchronously to realize the opening and closing of the channel, so that the opening and closing blades can rotate synchronously, and then accurately realize the opening and closing of the channel, ensuring that the channel can be stably opened when needed to allow the paint to pass smoothly, and the channel can be reliably closed when not needed, avoiding problems such as paint leakage.

[0023] 6. The paint in the present invention flows into the inner wall of the fixed ring through the inner wall of the rotating ring, enters through the triangular diffusion hole at one end of the diffusion disk, and finally sprays out through the circular hole with a larger diameter at the other end of the diffusion hole. The triangular inlet helps to guide the paint to enter, and the circular outlet allows the paint to be sprayed out in a more uniform manner, which optimizes the spraying form of the paint and is conducive to the uniform distribution of the paint and better use effect.
