Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, and in particular to a powder coating device for an inverter housing. Background Technology

[0002] Powder coating is a surface treatment method that involves spraying plastic powder onto parts. Also known as electrostatic powder coating, it offers advantages over conventional painting in terms of advanced technology, energy efficiency, safety, reliability, and vibrant colors. Therefore, it is frequently used in light industry and home decoration.

[0003] For example, CN222385119U discloses a powder coating device for an inverter housing, including a housing, a door connected to the front end of the housing via a hinge, a handle fixedly connected to the front end of the door, a rotating mechanism provided at the lower end of the housing, the rotating mechanism being used to drive the inverter housing to rotate; a power mechanism and a powder coating mechanism provided at the upper end of the housing, the power mechanism being used to drive the powder coating end of the powder coating mechanism to move.

[0004] However, in the existing technology, when the powder coating equipment cannot accurately adapt to the size of the workpiece, it is easy to cause over-spraying or uneven spraying of paint. Over-spraying can also lead to excess paint being wasted in the air or on the ground around the workpiece, thereby increasing paint consumption and production costs. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that when the workpiece size cannot be accurately matched, the paint may be over-sprayed or unevenly sprayed, and to propose a powder coating device for inverter housing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a powder coating device for an inverter housing, comprising a mounting frame, wherein a powder coating mechanism is mounted on the bottom of the mounting frame;

[0007] The powder coating mechanism includes a rotating plate, a limit plate that is slidably connected to the inner side of the rotating plate, a second fixed frame that is fixedly connected to the bottom of the limit plate, a first fixed frame that is fixedly connected to the bottom of the rotating plate, a limit sleeve that is fixedly connected to the inner side of the first fixed frame, a limit rod that is slidably connected to the inner side of the limit sleeve, a second fixed frame that is fixedly connected to one end of the limit rod, a fixed rod that is fixedly connected to one side of the second fixed frame, a rotating tube that is rotatably connected to one end of the fixed rod, and a powder coating head that is fixedly connected to the bottom of the rotating tube.

[0008] Preferably, two movable plates are slidably connected to the inner side of the mounting frame, and a movable frame is fixedly connected to one end of each movable plate.

[0009] Preferably, the bottom of the movable frame is fixedly connected to both sides of the fixed plate, and the fixed plate is fitted with a track.

[0010] Preferably, the fixing plate is threaded with a threaded rod, and the threaded rod is threadedly connected to the track.

[0011] Preferably, a limiting block is fixedly connected to one end of the top of the limiting plate, and the limiting block is slidably connected to the track.

[0012] Preferably, a drive motor is installed at the center of the top of the mounting bracket.

[0013] Preferably, the output end of the drive motor is rotatably connected to the center of the top of the rotating plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the rotating plate drives the powder coating head to achieve dynamic adjustment, which effectively improves the comprehensiveness and flexibility of powder coating coverage. The relative sliding of the limiting rod and the limiting sleeve plays a buffering and adjusting role, ensuring the stability of the coordinated movement of each component and avoiding impact and jamming. The relative sliding of the limiting plate and the rotating plate enhances the adaptability of the mechanism, enabling the powder coating head to flexibly cope with the spraying requirements of different angles and directions. The guiding movement of the limiting block in the track ensures that the powder coating head moves stably along the predetermined path, avoiding positional deviation and improving the accuracy and consistency of spraying. The overall structure optimizes the powder coating process and achieves a high-efficiency, dead-angle-free spraying effect.

[0016] 2. In this utility model, by setting a replaceable track, the device can flexibly adapt to inverter housings of different sizes, significantly improving the versatility and adaptability of powder coating operations. The track is easy to replace, and with the threaded rod for clamping and fixing, it ensures the guiding stability during the powder coating process. The relative sliding between the limiting plate and the rotating plate, and between the limiting rod and the limiting sleeve, allows the internal structure to be automatically adjusted according to the track size, maintaining a reasonable spatial layout. The adjustment of the powder coating head angle relies on the relative rotation of the rotating tube and the fixed rod, and the angle is fixed by the locking component, effectively ensuring uniform spray coverage without dead corners. The overall system design is compact and efficient, improving the powder coating quality and operational flexibility. Attached Figure Description

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-4 As shown, this utility model provides a powder coating device for an inverter housing, including a mounting frame 1, and a powder coating mechanism 4 is installed at the bottom of the mounting frame 1;

[0025] The powder coating mechanism 4 includes a rotating plate 41, a limiting plate 44 slidably connected to the inner side of the rotating plate 41, a second fixing frame 46 fixedly connected to the bottom of the limiting plate 44, a first fixing frame 42 fixedly connected to the bottom of the rotating plate 41, a limiting sleeve 43 fixedly connected to the inner side of the first fixing frame 42, a limiting rod 45 slidably connected to the inner side of the limiting sleeve 43, a second fixing frame 46 fixedly connected to one end of the limiting rod 45, a fixing rod 461 fixedly connected to one side of the second fixing frame 46, a rotating tube 48 rotatably connected to one end of the fixing rod 461, and a powder coating head 47 fixedly connected to the bottom of the rotating tube 48.

[0026] The specific settings and functions of this embodiment are described below. During powder coating of the inverter casing, the powder coating head 47 can be used to uniformly coat the surface of the casing. To ensure more comprehensive coverage, the angle and position of the powder coating head 47 can be dynamically adjusted during the powder coating process by rotating the rotating plate 41. When the rotating plate 41 rotates, it drives the first fixed frame 42 to move synchronously. At this time, the first fixed frame 42 drives the second fixed frame 46 to move through the limiting plate 44. Furthermore, the limiting block 49 slides along the inside of the track 32, thereby achieving stability of the powder coating head 47 during powder coating in different directions. This facilitates a full-coverage, no-dead-angle coating effect on all sides, corners, and irregular areas of the inverter casing.

[0027] During the rotation and adjustment process, the limiting rod 45 slides relative to the limiting sleeve 43. This relative movement buffers and adjusts the tension between the components, ensuring smooth and stable movement. Simultaneously, the limiting plate 44 can also slide relative to the rotating plate 41 within a certain range, further enhancing the system's flexibility and adaptability during adjustment. The movement of the limiting block 49 within the track 32 not only changes the position of the spray head 47 but also provides significant guidance, ensuring the spray head 47 moves stably along the set path during adjustment, preventing positional drift or spraying errors, and improving the overall efficiency and quality of the spray coating operation.

[0028] Example 2: Figure 2 and Figure 3 As shown, two movable plates 31 are slidably connected to the inner side of the mounting frame 1, and a movable frame 3 is fixedly connected to one end of each movable plate 31. Fixed plates 33 are fixedly connected to both sides of the bottom of the movable frame 3, and rails 32 are snapped into the inner side of each fixed plate 33. A threaded rod 34 is threadedly connected to each fixed plate 33, and the threaded rod 34 is threadedly connected to the rail 32. A limit block 49 is fixedly connected to one end of the top of the limiting plate 44, and the limit block 49 is slidably connected to the rail 32. A drive motor 2 is mounted at the top center of the mounting frame 1. The output end of the drive motor 2 is rotatably connected to the top center of the rotating plate 41.

[0029] The overall effect of this embodiment is that, when powder coating inverter housings from the same batch, a replaceable track system 32 is provided to accommodate minor differences in the structural dimensions of the housings. Specifically, depending on the required track size, different specifications of tracks 32 can be selected and installed between the fixed plates 33 located inside the movable frame 3. After installation, the threaded rod 34 is rotated to connect with the fixed plate 33, thereby effectively pressing and fixing the track 32, ensuring its stability and precise guidance during the powder coating process.

[0030] As the dimensions of track 32 change, relative sliding can occur between the limiting plate 44 and the rotating plate 41. Through structural cooperation, the entire limiting system automatically adjusts according to the dimensions of track 32, thereby ensuring that the internal space of the equipment is always in a reasonable state. At the same time, relative sliding can also occur between the limiting rod 45 and the limiting sleeve 43, further enhancing the compatibility of the entire mechanism with different track 32 dimensions, making the equipment more adaptable and versatile, and effectively improving production efficiency.

[0031] During the powder coating operation, the relative rotation between the rotating tube 48 and the fixed rod 461 on the powder coating mechanism 4 allows for flexible adjustment of the angle of the powder coating head 47. The rotating tube 48 can be equipped with a locking component to lock the angle, enabling the operator to adjust the spraying angle of the powder coating head 47 according to the shape of the inverter housing and the coating requirements. This ensures that the powder coating evenly covers the workpiece surface, avoiding spraying dead zones and uneven coating, thereby improving powder coating quality and appearance consistency. Furthermore, the angle adjustment mechanism of the powder coating head 47 is compact and easy to adjust, meeting the personalized coating needs of different batches of products.

[0032] The device's operation and working principle are as follows: When powder coating the inverter casing, the process can be performed via the powder coating head 47. During the full-coverage coating process, the rotating plate 41 rotates, causing the first fixed frame 42 to push the second fixed frame 46 to move via the limiting plate 44. Simultaneously, the limiting block 49 can move within the track 32, thereby facilitating the adjustment of the powder coating head 47's orientation and achieving full-range coating of the inverter casing.

[0033] During rotation, the limiting rod 45 and the limiting sleeve 43 slide relative to each other, and the limiting plate 44 can also slide relative to the rotating plate 41, so that the limiting block 49 can guide the adjustment of the spray head 47 when it moves in the track 32.

[0034] For the powder coating of inverter housings in the same batch, different specifications of rails 32 can be replaced according to the housing size. During installation, the rails 32 are fixed on the fixing plate 33 inside the movable frame 3, and then locked by the threaded rod 34. As the size of the rails 32 changes, the relative sliding between the limiting plate 44 and the rotating plate 41, and between the limiting rod 45 and the limiting sleeve 43, can adapt to the structure of rails 32 of different sizes.

[0035] During the powder coating process, the spraying angle of the powder coating head 47 can also be adjusted by rotating the rotating tube 48 and the fixed rod 461.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
