Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a spraying equipment for aluminum baking pans. Background Technology

[0002] Limitations of Traditional Spray Coating Equipment: In the field of aluminum baking pan coating, traditional spray coating equipment often has several shortcomings. For example, in some equipment, the baking pan rotation and spraying device are relatively independent, failing to achieve flexible rotation of the baking pan in three-dimensional space. This results in uneven coating, especially around the edges and corners of the baking pan, affecting coating quality. Furthermore, paint mist diffusion is a serious problem during spraying, and the lack of effective paint mist collection and treatment devices not only pollutes the environment and endangers the health of operators but may also pose safety hazards. In addition, the stability of the drive components in some equipment is poor, affecting the stability and accuracy of the baking pan rotation, thus impacting the coating effect.

[0003] Chinese patent discloses a baking tray spraying device with paint collection function (publication number: CN 220573831U), which includes a shell, a support plate fixedly connected to the upper side of the shell, a top plate fixedly connected to the upper side of the support plate, a drying mechanism on the shell, a through hole on the shell, a baking tray rack inside the shell, and connecting blocks fixedly connected to the outer sides of the baking tray rack away from both sides. A sliding mechanism is provided on one side of each connecting block. However, this baking tray spraying device suffers from severe paint mist diffusion during the spraying process, lacking an effective paint mist collection and treatment device. This not only pollutes the environment and endangers the health of operators but may also pose safety hazards. Furthermore, the poor stability of some equipment's drive components affects the stability and accuracy of the baking tray rotation, thus affecting the spraying effect. Therefore, there is a need for an aluminum baking tray surface spraying device. Utility Model Content

[0004] The purpose of this invention is to address the serious problem of paint mist diffusion during the spraying process in existing baking pan spraying equipment. The lack of effective paint mist collection and treatment devices not only pollutes the environment and endangers the health of operators but also poses potential safety hazards. Furthermore, some equipment suffers from poor stability of its drive components, affecting the stability and precision of the baking pan rotation and consequently impacting the spraying effect. Therefore, this invention proposes a spraying device for aluminum baking pan surfaces.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An aluminum baking pan surface spraying device, comprising a base, characterized in that: a hollow rotating platform is provided above the base; a spraying robotic arm assembly is provided above the hollow rotating platform; a rotating mounting frame is provided above the hollow rotating platform; small turntables are provided at both ends of the rotating mounting frame; a baking pan spraying rack is provided on the top of the small turntables; a rotary motor is provided at the bottom of the small turntables and is associated with the rotating mounting frame; a drive assembly for rotating the hollow rotating platform is provided on one side; and an anti-paint mist diffusion component is provided below the baking pan spray head frame. The overall structure is reasonably designed. Through the cooperation of the hollow rotating platform, small turntables, and rotary motor, the baking pan can rotate flexibly in three-dimensional space, ensuring that every part of the baking pan surface receives uniform spraying, thus improving the spraying quality. The anti-paint mist diffusion component effectively avoids paint mist pollution of the surrounding environment, protects the health of operators, and also helps maintain a clean working environment, meeting environmental protection requirements.

[0006] Preferably, the drive assembly includes a motor mounting bracket, with a main drive motor located on one side of the inner wall of the mounting bracket. By including the motor mounting bracket and the main drive motor, the structure of the drive assembly becomes more stable and reliable. The main drive motor provides stable and adjustable power output, ensuring uniform rotation speed of the hollow rotary table, thereby guaranteeing the stability and uniformity of the baking tray during the spraying process and further improving the spraying effect. Simultaneously, this design facilitates the maintenance and replacement of the drive motor, reducing equipment maintenance costs.

[0007] Preferably, the baking tray spraying rack has a baking tray grid on top and an L-shaped baffle on one side. The baking tray grid design makes the baking tray more stable during spraying, avoiding uneven spraying caused by shaking or tilting. The L-shaped baffle not only effectively prevents objects on the baking tray from flying off and causing safety hazards, but also guides airflow to a certain extent, making it easier for paint mist to be extracted by the exhaust box, improving the effect of preventing paint mist diffusion, and further enhancing the safety and cleanliness of the working environment.

[0008] Preferably, the spraying robotic arm assembly includes an X-axis robotic arm, a Y-axis robotic arm, and a Z-axis robotic arm, with a paint spray nozzle at one end of the Z-axis robotic arm. This multi-axis robotic arm design allows the paint spray nozzle to move flexibly in three-dimensional space, enabling precise spraying of various parts of the baking tray surface, especially for baking trays with complex shapes. This improves spraying accuracy and efficiency, reduces paint waste, and ensures coating uniformity and thickness consistency, thereby enhancing product quality.

[0009] Preferably, the rotary mounting bracket has two reinforcing ribs at both ends of its top. The reinforcing ribs effectively improve the load-bearing capacity of the rotary mounting bracket, making it less prone to deformation when supporting the weight of the baking tray and rotating components. This helps ensure the stability of the baking tray during rotation, reducing vibration and shaking, thereby improving the quality and precision of the coating process. Simultaneously, a stable rotary mounting bracket also extends the service life of the equipment and reduces its failure rate.

[0010] Preferably, the anti-paint mist diffusion component includes an external circulating exhaust box, one end of which is equipped with an air supply duct, and the other end of which is equipped with a purification activated carbon box. The combined use of the external circulating exhaust box and the purification activated carbon box can efficiently collect and treat paint mist, preventing its diffusion within the working area. Activated carbon has a strong adsorption capacity, effectively removing paint mist particles and harmful gases from the air, purifying the air, and protecting the environment. Simultaneously, the circulating air utilization method saves energy and reduces equipment operating costs.

[0011] The advantages of this utility model are:

[0012] This application utilizes a hollow rotary table, a small rotary table, and a rotary motor to enable the baking tray to rotate flexibly in three-dimensional space, ensuring uniform coating on all parts of the tray surface. Combined with a multi-axis spraying robotic arm capable of precise positioning and movement, this further improves spraying accuracy, resulting in a more uniform coating with consistent thickness, thus enhancing product quality and stability. The anti-paint mist diffusion component effectively prevents paint mist from polluting the surrounding environment, protecting the health of operators. An external circulating exhaust box, working in conjunction with a purification activated carbon box, efficiently collects and treats paint mist and harmful gases, purifying the air and reducing environmental pollution. It also avoids potential safety hazards caused by paint mist diffusion, such as slippery floors and fire risks. The structural design facilitates the loading, unloading, and securing of the baking tray. The tray grid and L-shaped baffles help to better secure the tray and prevent objects from flying off. Furthermore, the modular design of each component facilitates maintenance and replacement, reducing equipment repair costs and complexity. Attached Figure Description

[0018] 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 scope of protection of the present utility model.

[0019] Example

[0020] Please see Figure 1-3 As shown, an aluminum baking pan coating equipment includes a base 14. The equipment is characterized by: a hollow rotating platform 9 above the base 14; a coating robotic arm assembly 19 above the hollow rotating platform 9; a rotating mounting frame 7 above the hollow rotating platform 9; small turntables 15 at both ends of the rotating mounting frame 7; a baking pan coating rack 5 on top of the small turntables 15; a rotary motor 16 at the bottom of the small turntables 15 and associated with the rotating mounting frame 7; a drive assembly for rotating the hollow rotating platform 9 on one side; and an anti-paint mist diffusion assembly below the baking pan spray head frame. The overall structure is rationally designed. Through the cooperation of the hollow rotating platform 9, the small turntables 15, and the rotary motor 16, the baking pan can rotate flexibly in three-dimensional space, ensuring that every part of the baking pan surface receives uniform coating, thus improving coating quality. The anti-paint mist diffusion assembly effectively avoids paint mist pollution of the surrounding environment, protects the health of operators, and also helps maintain a clean working environment, meeting environmental protection requirements.

[0021] In this embodiment, the drive assembly includes a motor mounting bracket 18, and a main drive motor 17 is provided on one side of the inner wall of the motor mounting bracket 18. By setting the motor mounting bracket 18 and the main drive motor 17, and using a commercially available product, the main drive motor 17 makes the structure of the drive assembly more stable and reliable. The main drive motor 17 can provide stable and adjustable power output, ensuring uniform rotation speed of the hollow rotary table 9, thereby ensuring the stability and uniformity of the baking tray during the spraying process and further improving the spraying effect. At the same time, this design facilitates the maintenance and replacement of the drive motor, reducing the equipment maintenance cost.

[0022] In this embodiment, the baking tray spraying rack 5 has a baking tray grid 6 on top and an L-shaped baffle 4 on one side. The design of the baking tray grid 6 makes the baking tray more stable during the spraying process, avoiding uneven spraying due to shaking or tilting. The L-shaped baffle 4 not only effectively prevents objects on the baking tray from flying off and causing safety hazards, but also guides airflow to a certain extent, making it easier for paint mist to be extracted by the exhaust box, improving the effect of preventing paint mist diffusion, and further enhancing the safety and cleanliness of the working environment.

[0023] In this embodiment, the spraying robotic arm assembly 19 includes an X-axis robotic arm 13, a Y-axis robotic arm 12, and a Z-axis robotic arm 11, with a paint spray nozzle 10 at one end of the Z-axis robotic arm 11. This multi-axis robotic arm design allows the paint spray nozzle 10 to move flexibly in three-dimensional space, enabling precise spraying of various parts of the baking tray surface, especially for baking trays with complex shapes. This improves the accuracy and efficiency of spraying, reduces paint waste, and ensures the uniformity and thickness consistency of the coating, thereby improving product quality.

[0024] In this embodiment, two reinforcing ribs 8 are provided at both ends of the top of the rotary mounting bracket 7. The reinforcing ribs 8 are arranged in a corresponding manner. The reinforcing ribs 8 effectively improve the load-bearing capacity of the rotary mounting bracket 7, making it less prone to deformation when bearing the weight of the baking tray and rotating components. This helps ensure the stability of the baking tray during rotation, reducing vibration and shaking, thereby improving the quality and precision of the coating. Simultaneously, a stable rotary mounting bracket 7 also extends the service life of the equipment and reduces its failure rate.

[0025] In this embodiment, the anti-paint mist diffusion component includes an external circulating exhaust box 3. One end of the external circulating exhaust box 3 is equipped with an air supply duct 2, and the other end of the air supply duct 2 is equipped with a purification activated carbon box 1. The combined use of the external circulating exhaust box 3 and the purification activated carbon box 1 can efficiently collect and treat paint mist, preventing it from spreading within the working area. Activated carbon has a strong adsorption capacity, effectively removing paint mist particles and harmful gases from the air, purifying the air, and protecting the environment. Simultaneously, the circulating air utilization method saves energy and reduces the operating costs of the equipment.

[0026] The implementation principle of this embodiment is as follows: The rotating motion of the baking tray: The hollow rotary table 9 begins to rotate under the drive of the drive assembly (the main drive motor 17 within the motor mounting bracket 18), causing the rotating mounting bracket 7 above it and the baking tray to rotate together, thus achieving angle adjustment of the baking tray in the horizontal direction. Simultaneously, the rotary motor 16 at the bottom of the small turntable 15 drives the baking tray to rotate on the small turntable 15, allowing the baking tray to tilt in the vertical plane. This allows the baking tray to flexibly change its angle in three-dimensional space, facilitating the spraying robot arm to spray various parts of the baking tray.

[0027] Spraying process: The spraying robot arm assembly 19, by controlling the coordinated movement of the X-axis, Y-axis, and Z-axis robot arms 11, moves the paint nozzle 10 to a suitable position above the baking tray. Paint is sprayed from the nozzle 10, and as the baking tray rotates, the paint adheres evenly to its surface. The paint nozzle 10 at one end of the Z-axis robot arm 11 can be precisely adjusted according to the shape of the baking tray and spraying requirements to ensure accurate spraying of the paint onto the tray surface.

[0028] Paint mist control mechanism: During the spraying process, the anti-paint mist diffusion component starts working. The external circulating exhaust box 3 is activated, generating negative pressure, which draws air from the work area into the air supply duct 2. When the air passes through the activated carbon purification box 1, the activated carbon adsorbs the paint mist particles and harmful gases. The purified air then returns to the work area or is exhausted outdoors through the air supply duct 2, forming a circulating air purification system that effectively prevents paint mist from spreading within the work area.
