This method has two drawbacks: firstly, manual painting is inefficient and, due to skill limitations, easily leads to uneven paint application and unwanted defective products. Secondly, manual painting also poses health risks to workers. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a plastic shell painting device to solve the problem that there is no device in the prior art that can paint small plastic shells.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a plastic shell painting device, comprising: a paint tank, which provides space for painting the plastic shell; a base, which is capable of reciprocating within the paint tank; a rotating disk, which supports the plastic shell and is mounted on the base and capable of rotating relative to the base; and a sliding disk, which is rotatably connected to the outside of the rotating disk and is used to adjust the angle of the rotating disk within the paint tank.

[0005] Optionally, the paint tank includes a bottom tank, with side baffles fixed on both sides of the bottom tank, a material channel provided on one side of the side baffle, and a support fixed between the side baffles, the support being fixedly connected to the bottom tank.

The first transmission wheel is driven by a motor. The base has a cavity to accommodate the motor. The first transmission wheel and the second transmission wheel are connected by a transmission belt. A toothed ring is fixed around the second transmission wheel. A toothed plate that meshes with the toothed ring is fixed in the accommodating space.

[0008] Optionally, the transmission wheel two is rotatably connected to the base via a rotating shaft two. A bevel gear two is fixed at the end of the rotating shaft two away from the transmission wheel two. A bevel gear one meshes with the bevel gear two. A rotating shaft one connected to the rotating disk is fixed on the bevel gear one. The rotating shaft two, bevel gear one, bevel gear two, and rotating shaft one are also arranged in the cavity.

[0009] Optionally, the rotating disk has a connecting part on the side near the base, and the connecting part and the rotating shaft are connected by a universal joint.

[0010] Optionally, a guide rail is fixed to the side of the support near the sliding disk, and a bent portion is provided at the end of the guide rail near the material channel.

This frees up manual labor, avoids the health hazards of paint to workers, and improves the painting efficiency of plastic casings.

[0016] The rotating disk designed in this invention can rotate while the base moves, thereby causing the plastic shell mounted on it to rotate, ensuring that every surface of the shell is evenly painted. This design improves the quality of the finished product and avoids the problem of rejects caused by uneven painting.

[0017] This invention, after the painting assembly has finished painting the plastic casing, allows the rotating disc to tilt by manipulating the sliding disc, causing the plastic casing on the rotating disc to slide off, thus achieving the function of unloading the material.

[0027] 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.

[0028] As mentioned earlier, in the prior art, the plastic shells of electric tricycles, such as mudguards and plastic covers, are usually painted manually. This method has several drawbacks: firstly, manual painting is inefficient and, due to skill limitations, easily leads to uneven paint surfaces, resulting in unwanted defective products. Secondly, manual painting also poses health risks to workers. To address these issues, this invention provides a painting device that solves the problem of automatic painting of small and medium-sized plastic shells. This invention solves the problem in the following ways.

[0029] Example 1:

[0030] Please refer to the instruction manual appendix. Figures 1 to 2 , Figure 4 This utility model discloses a plastic shell painting device, which includes at least a paint tank 1, a painting assembly, a base 2, a rotating disk 3, and a sliding disk 4. The rotating disk 3 has a protruding strip 31 fixed to its outer periphery facing the plastic shell. The protruding strip 31 is made of silicone material, allowing the plastic shell to be held in place or surrounded by the protruding strip 31 when placed on the rotating disk 3, thus preventing it from falling due to the impact of the sprayed paint. The paint tank 1 provides space for painting the plastic shell and includes a bottom tank 5 containing a liquid for absorbing paint mist. During use, the paint mist sprayed onto the plastic shell by the painting assembly settles into the liquid in the bottom tank 5 under gravity, mixes, and is then discharged. Side baffles 6 are fixed to both sides of the bottom tank 5. One side baffle 6 has a notch that connects to a material channel 7. A support 8 is fixed between the side baffles 6, and the support 8 is fixedly connected to the bottom tank 5.

[0031] In this first embodiment, the painting assembly includes a spray head 27, which is fixed to a support 8 by a support rod 28. A paint storage component 29 is provided on the side of the support 8 away from the rotating disk 3. The paint storage component 29 and the spray head 27 are connected by a paint pipe 30. In use, an additional power source (e.g., an air compressor, hydraulic equipment, or electric motor) is connected to the spray head 27 to extract the paint from the paint storage component 29, which is then transported to the spray head 27 via the paint pipe 30 and finally sprayed out, achieving the painting effect.

[0032] In this embodiment, the base 2 can reciprocate within the paint tank 1, while the rotating disk 3, which carries the plastic shell, can rotate relative to the base 2. During use, the base 2 moves the plastic shell from one side of the spray nozzle 27 to the other. During this process, the rotating disk 3 completes at least one full rotation, ensuring that every surface of the plastic shell faces the spray nozzle 27, ultimately achieving a uniform paint spraying effect. The sliding disk 4 is rotatably connected to the rotating disk 3 (e.g., the rotating disk 3 and the sliding disk 4 are connected by bearings), and moves along with the base 2 and the rotating disk 3 during their movement. When the base 2 moves close to the feed channel 7, the painting of the plastic shell is nearing completion. At this point, the sliding disk 4 is tilted towards the feed channel 7, and the plastic shell falls from the rotating disk 3 into the feed channel 7 under gravity, thus completing the discharge process.

[0033] It should be noted that when the plastic casing is painted or about to be painted (i.e., between the nozzle 27 and the feed channel 7), the paint is not yet completely dry. At this time, tilting the sliding disc 4 can easily cause an impact between the plastic casing and the feed channel 7, resulting in damage to the newly painted paint. To avoid this, the plastic casing needs to remain between the nozzle 27 and the feed channel 7 for a certain period of time to dry after painting. To accelerate this drying process, in this embodiment, a drying device (e.g., a hot air dryer) can be added between the nozzle 27 and the feed channel 7. When the drying device is powered on, it blows warm air perpendicular to the moving axis of the plastic casing, accelerating the drying of the paint and avoiding the aforementioned problem.

[0034] Example 2:

[0035] Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions therein, this utility model also provides an embodiment two. For example... Figures 2 to 4 In this second embodiment, the support portion 8 has a receiving space 9, and a guide plate 10 is fixed in the receiving space 9. A sliding groove 11 is provided on the side of the base 2 near the receiving space 9, and the guide plate 10 is engaged in the sliding groove 11. Therefore, by applying a force to the base 2 along the direction of the guide plate 10, the base 2 can be driven to slide on the guide plate 10.

[0036] In order to achieve the above-mentioned sliding function, in this second embodiment, as follows: Figure 4 As shown, a transmission wheel 12 and a transmission wheel 13 are rotatably connected to the side of the base 2 near the accommodating space 9. The transmission wheel 12 is driven by a motor 14. The base 2 has a cavity 15 to accommodate the motor 14. The transmission wheel 12 and the transmission wheel 13 are connected by a transmission belt 16. A toothed ring 17 is fixed around the transmission wheel 13. A toothed plate 18 that meshes with the toothed ring 17 is fixed in the accommodating space 9.

[0037] Therefore, in the specific implementation of this embodiment, the motor 14 is energized and driven to rotate, and its output shaft drives the transmission wheel 12 to rotate. Through the transmission belt 16, the transmission wheel 13 starts to rotate. Since the gear ring 17 and the transmission wheel 13 are fixedly connected, the gear ring 17 starts to rotate. Under the action of the gear plate 18, the gear ring 17 and the transmission wheel 13 fixedly connected to it are displaced relative to the gear plate 18, thereby driving the base 2 to move.

[0038] Example 3:

[0039] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Three. For example... Figures 3 to 4 As shown, in this embodiment three, a rotating shaft 19 is fixedly connected to the transmission wheel 13. A bevel gear 20 is fixed to one end of the rotating shaft 19 away from the transmission wheel 13. A bevel gear 21 meshes with the bevel gear 20. A rotating shaft 22 connected to the rotating disk 3 is fixed to the bevel gear 21. The rotating shaft 19, bevel gear 21, bevel gear 20, and rotating shaft 22 are all arranged in the cavity 15.

[0040] Therefore, in the specific implementation of this third embodiment, the drive method described in embodiment two drives the transmission wheel 13 to rotate, thereby driving the rotating shaft 19 to rotate, which in turn drives the bevel gear 20 to rotate and continuously meshes with the bevel gear 21, ultimately driving the rotating shaft 22 to rotate. Since the rotating shaft 22 is connected to the rotating disk 3, the rotating disk 3 can rotate while the base 2 moves, ultimately achieving the uniform painting effect described in the aforementioned embodiments.

[0041] Example 4:

[0042] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Four. For example... Figures 2 to 6 As shown, in this fourth embodiment, a guide rail 25 is fixed to the side of the support part 8 near the sliding disk 4. The guide rail 25 is arranged along the direction of movement of the base 2, and a bent portion is provided at the end near the material channel 7, with the bent portion facing the material channel 7. Two sliding columns 26 are fixed to the side of the sliding disk 4 near the support part 8, and the sliding columns 26 slide within the guide rail 25.

[0043] Therefore, as the sliding disk 4 moves with the base 2, the sliding column 26 continues to slide within the guide rail 25 until the sliding column 26 closest to the material channel 7 enters the bent section. At this point, the sliding disk 4 tilts horizontally, causing the rotating disk 3 connected to it to also tilt. When the rotating disk 3 tilts to the point where the plastic casing it carries is sufficient to fall, the sliding disk 4 and the material channel 7 align, and the plastic casing slides off the rotating disk 3 and into the material channel 7, thus completing the discharge step in the aforementioned embodiment.

[0044] To ensure that the rotation of the rotating disk 3 and the tilting of the sliding disk 4 do not interfere with each other during the two processes, in this embodiment, the rotating disk 3 is provided with a connecting part 23 (e.g., ...) on the side near the base 2. Figure 4 As shown, the connecting part 23 and the rotating shaft 22 are connected by a universal joint 24. The universal joint 24 can transmit torque and rotational motion within a certain angle range, thereby realizing variable angle transmission. This allows the rotating disk 3 to perform rotational and tilting movements simultaneously without motion interference. This satisfies the above-mentioned functions of uniform painting and material discharge.

[0045] In summary, the plastic shell painting device provided by this utility model, based on the above embodiments, has the following advantages compared to the prior art, including but not limited to:

[0046] This invention enables automatic painting of plastic shells by using a base 2 to support a rotating disk 3 that reciprocates within a paint tank 1, supplemented by a painting device. This frees up manual labor, avoids the health hazards of paint to workers, and improves the painting efficiency of plastic shells.

[0047] The rotating disk 3 designed in this invention can rotate while the base 2 is moving, thereby causing the plastic shell mounted on it to rotate, ensuring that every surface of the shell is evenly painted. This design improves the quality of the finished product and avoids the problem of defective products caused by uneven painting.

[0048] After the paint spraying assembly finishes painting the plastic casing, this invention allows the sliding disk 4 to tilt the rotating disk 3, causing the plastic casing on the rotating disk 3 to slide off, thus achieving the function of unloading the material. This eliminates the need for manual unloading of the plastic casing, further improving the automation level of the equipment.

[0049] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
