Description

Technical Field

[0001] This utility model relates to the field of bicycle parts painting, and in particular to a bicycle parts painting device. Background Technology

[0002] Bicycle accessories refer to various parts used to assemble, repair, or enhance the functionality of bicycles, covering performance, safety, and aesthetic requirements. These include components such as frames, wheels, drivetrains, brake assemblies, suspension systems, saddles, pedals, lights, mudguards, and decorative parts. They are designed according to materials, uses, and compatibility to improve riding efficiency, comfort, or personalization.

[0003] In the painting process of bicycle parts, operators often find it difficult to precisely control the spraying angle and distance, resulting in incomplete paint film coverage on complex geometric edges. This not only affects the uniformity of the product's appearance but also significantly reduces the corrosion resistance of critical parts. At the same time, the natural drying process, which relies on ambient temperature, has a double defect: its slow curing speed can easily cause paint film sagging, forming surface defects, and the long-term exposure to the open environment increases the risk of dust particle adhesion, ultimately leading to quality defects such as orange peel and particles in the coating, which seriously affects the product's aesthetics and durability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bicycle accessory painting device. This device solves the problems of incomplete edge coverage and uneven film thickness caused by spraying, significantly improves corrosion resistance and appearance consistency, effectively prevents surface defects such as orange peel and particles, and enhances coating quality and durability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A bicycle accessory painting device includes a support platform for support, a rotating platform rotatably connected to the top of the support platform, multiple rotating rods rotatably connected around the inside of the rotating platform, a rotating limiting plate fixedly connected to the top of each rotating rod, the rotating limiting plate rotatably connected to the top of the rotating platform, and a clamping frame fixedly connected to the top of each rotating limiting plate. A right support frame is fixedly connected to the right side of the top of the support platform, a right limiting frame is fixedly connected to the inner side of the right support frame, and a painting assembly is installed inside the right limiting frame. A circumferential rotating assembly is installed on the top of the support platform for multi-angle adjustment of the accessory. A left support frame is fixedly connected to the left side of the top of the support platform, and a drying assembly is installed on the inner side of the left support frame for rapid paint adhesion.

[0006] Furthermore, the drying assembly includes a left limiting frame fixed inside the left support frame, a heating block fixedly connected to the top of the left limiting frame, an air pump fixedly connected to the top of the left support frame, a transmission air pipe fixedly connected to the output end of the air pump, a transmission air pipe fixedly connected to the front end of the heating block inside the air pump, and a heating wire fixedly connected inside the heating block.

[0007] Furthermore, the painting assembly includes a paint block fixed at the top of the right limiting frame, a pigment tank fixedly connected to the top of the right support frame, a transfer pipe fixedly connected to the front end of the pigment tank, the inner side of the transfer pipe fixedly connected to the front end of the paint block, and a transfer pump fixedly connected to the outer side of the transfer pipe in front of the pigment tank.

[0008] Furthermore, the circumferential rotating assembly includes a gear ring fixedly connected to the top of the support platform, a gear fixedly connected to the outside of the rotating rod, the gear meshing with the gear ring, and the lower outer side of the rotating rod slidably connected to the top of the support platform.

[0009] Furthermore, a drive motor is fixedly connected to the center of the bottom end of the support platform, and the drive end of the drive motor is fixedly connected to the bottom end of the rotating rod.

[0010] Furthermore, multiple blocking curtains are fixedly connected to both sides of the right-side limiting frame.

[0011] Furthermore, a lower exhaust frame is fixedly connected to the bottom end of the heating block, and the exterior of the lower exhaust frame extends through the bottom end of the left limiting frame.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the rotating table is driven by a drive motor to revolve, and the gear fixed to the rotating rod meshes with the gear ring on the support plate to drive the transmission. This forces the clamping frame to rotate synchronously during the revolution. The paint block, driven by the transfer pump, atomizes and sprays the paint from the pigment can. In conjunction with the blocking curtains set on both sides of the right limiting frame to constrain the spray diffusion range, it ensures that the paint mist accurately adheres to the surface of the accessory with continuously changing angles. This solves the problems of incomplete edge coverage and uneven film thickness caused by spraying, and significantly improves corrosion resistance and appearance consistency.

[0013] 2. In this utility model, air is pumped into the heating block through the transmission air pipe by an air pump. After the internal heating wires rapidly raise the temperature, the hot air is blown directionally from the bottom of the heating block to the rotating parts. Under the combined motion of the parts' revolution and rotation, the parts are dried evenly, which effectively prevents surface defects such as orange peel and particles, and improves the coating quality and durability.

[0016] 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.

[0017] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a bicycle accessory painting device, comprising a support platform 1 for support, a rotating platform 2 rotatably connected to the top of the support platform 1, a plurality of rotating rods 22 rotatably connected to the inside of the rotating platform 2, a rotating limiting plate 16 fixedly connected to the top of each rotating rod 22, a clamping frame 3 fixedly connected to the outside of the rotating limiting plate 16 on the top of the rotating platform 2, a right support frame 8 fixedly connected to the right side of the top of the support platform 1, a right limiting frame 10 fixedly connected to the inside of the right support frame 8, a painting component installed inside the right limiting frame 10, a circumferential rotating component installed on the top of the support platform 1 for multi-angle adjustment of the accessory, and a left support frame 15 fixedly connected to the left side of the top of the support platform 1, a drying component installed inside the left support frame 15. The components are designed to enable rapid paint adhesion. The paint spraying assembly includes a paint block 9 fixed at the top of the right limiting frame 10, a pigment tank 7 fixedly connected to the top of the right support frame 8, a transfer pipe 5 fixedly connected to the front end of the pigment tank 7, a transfer pump 6 fixedly connected to the front end of the paint block 9 on the inner side of the transfer pipe 5, and a transfer pump 6 fixedly connected to the front side of the pigment tank 7 on the outer side of the transfer pipe 5. The rotating assembly includes a gear ring 19 fixedly connected to the top of the support platform 1, a gear 18 fixedly connected to the outer side of the rotating rod 22, the gear 18 and the gear ring 19 meshing with each other, the lower outer side of the rotating rod 22 slidingly connected to the top of the support platform 1, a drive motor 21 fixedly connected to the middle of the bottom end of the support platform 1, the drive end of the drive motor 21 fixedly connected to the bottom end of the rotating rod 20, and multiple blocking curtains 4 fixedly connected to both sides of the right limiting frame 10. When the device is working, the parts to be painted are firmly fixed in the clamping frame 3. After the drive motor 21 starts, it drives the rotating rod 20 and the rotating platform 2 to revolve. At the same time, the gear 18 installed on the rotating rod 22 meshes with the fixed gear ring 19 on the support plate 1, driving the rotating rod 22 to rotate inside the rotating platform 2. This, in turn, drives the clamping frame 3 to rotate synchronously through the rotating limit plate 16, thus realizing the compound rotational motion of the parts. During the painting process, the transfer pump 6 delivers the paint in the pigment tank 7 to the paint spray block 9 through the transfer pipe 5 for atomized spraying. With the help of the blocking curtain 4, the range of paint splashing is effectively controlled. Through this compound motion of revolution and rotation, the atomized paint can evenly cover all surfaces of the parts, significantly improving the uniformity and overall effect of the painting.

[0018] Reference Figure 1 and Figure 3The drying assembly includes a left limiting frame 11 fixed inside the left support frame 15. A heating block 12 is fixedly connected to the top of the left limiting frame 11. An air pump 13 is fixedly connected to the top of the left support frame 15. A transmission air pipe 14 is fixedly connected to the output end of the air pump 13. The inner side of the transmission air pipe 14 is fixedly connected to the front end of the heating block 12. A heating wire 23 is fixedly connected inside the heating block 12. A lower exhaust frame 17 is fixedly connected to the bottom end of the heating block 12. The outer side of the lower exhaust frame 17 penetrates the bottom end of the left limiting frame 11. When the parts are transferred to the drying area, the air pump 13 delivers compressed air to the heating block 12 through the transmission air pipe 14. After being heated by the internal heating wire 23, it forms a hot airflow that is evenly blown onto the surface of the parts. In the closed cavity formed by the left limiting frame 11, the hot air circulation accelerates the curing of the paint film, significantly shortens the exposure time of the paint film in the open environment, and effectively avoids the adsorption of dust particles. This design not only inhibits the formation of surface defects such as orange peel and particles, but also improves the uniformity, adhesion and overall durability of the coating, ensuring that the painting quality reaches the optimal effect.

[0019] Working principle: During operation, the parts to be painted are fixed in the clamping frame 3. After the drive motor 21 starts, it drives the rotating rod 20 and the rotating table 2 to revolve. At the same time, the gear 18 fixed to the rotating rod 22 meshes with the gear ring 19 on the support plate 1, forcing the rotating rod 22 to rotate within the rotating table 2. This drives the clamping frame 3 to rotate synchronously through the rotating limit plate 16, realizing the compound rotation of the parts. In the painting assembly, the transfer pump 6 pumps the paint from the pigment tank 7 into the paint block 9 through the transfer pipe 5 for atomization and spraying. The splashing range is limited by the baffle curtain 4 to ensure the parts are sprayed safely. The paint is evenly covered on all surfaces. Under the combined motion of the component's revolution and rotation, the atomized paint is evenly covered on all surfaces of the component, improving the painting effect of the device. Then the component is transferred to the drying area. The air pump 13 pressurizes air into the heating block 12 through the transmission air pipe 14. After being heated by the internal heating wire 23, the air is blown onto the surface of the component. The paint film is quickly cured in the cavity formed by the left limiting frame 11, which reduces the time that the paint film is exposed to adsorb dust particles in the open environment. This effectively prevents surface defects such as orange peel and particles, and improves the coating quality and durability.
