Description

Technical Field

[0001] This application relates to the technical field of an automatic painting device for aluminum winding reels for industrial doors, and in particular to an automatic painting device for aluminum winding reels for industrial doors. Background Technology

[0002] In the production and processing of aluminum winding wheels for industrial doors, the painting process, as a key step to ensure product corrosion resistance, extend service life, and improve appearance, has long relied on traditional processing methods, resulting in numerous operational inconveniences and technical bottlenecks. Specific problems include: Currently, most small and medium-sized manufacturing enterprises still use manual hand-held spray guns or brushes for painting. Due to the special structure of aluminum winding wheels, their surface has multiple sets of annular grooves, spoke connection points, and other complex curved surfaces, requiring frequent adjustments to the spraying angle and pressure during manual painting. On the one hand, paint accumulation in the deep grooves easily leads to runs, or incomplete spraying results in missed areas or exposed substrate. On the other hand, manual operation is affected by hand stability and work fatigue, resulting in paint film thickness differences of over 30% within the same batch of products. This cannot meet the stringent requirements for paint uniformity in industrial door accessories, necessitating significant manpower for subsequent grinding and repair, further increasing process costs. Therefore, those skilled in the art have provided an automatic painting device for aluminum winding wheels for industrial doors to solve the problems mentioned in the background. Utility Model Content

[0003] To address the problems mentioned in the background art, this application provides an automatic painting device for aluminum winding wheels of industrial doors.

[0004] The automatic painting device for aluminum winding wheels for industrial doors provided in this application adopts the following technical solution:

[0005] An automatic painting device for an aluminum winding reel for industrial doors includes an inclined plate, a vertical plate fixedly installed at the rear end of the inclined plate, a top plate fixedly installed at the top end of the vertical plate, a paint spray box fixedly installed at the upper end of the top plate, an inlet pipe connected to the upper end of the paint spray box, a conduit connected to the lower end of the paint spray box through the top plate, a diverter pipe fixedly installed at the lower end of the conduit pipe, and a spray pipe connected to the outside of the diverter pipe.

[0006] Preferably, a fixed slide rail groove is fixedly installed at the upper end of the inclined plate, and a sliding slide rail groove is provided at the upper end of the inclined plate.

[0007] Preferably, a fixing block is fixedly installed on the outside of the sliding rail groove, and a bolt passes through the upper end of the fixing block.

[0008] Preferably, a drying box is fixedly installed on the upper end of the top plate, and a metal mesh is fixedly installed on the upper end of the drying box.

[0009] Preferably, a blower is fixedly installed inside the drying oven, and the air outlet of the blower is connected to an air guide pipe.

[0010] Preferably, the air duct extends through the bottom of the top plate, and a heating rod is fixedly installed inside the air duct.

[0011] In summary, this application includes the following beneficial technical effects: After the winding wheel is painted, it continues to roll along the slide rail to the bottom of the drying system at the lower end of the inclined plate. At this time, the drying box is started simultaneously: the blower draws in external air and delivers it to the bottom of the top plate through the air duct; the heating rod inside the air duct heats the airflow to the set temperature (usually 60-80℃, suitable for the curing requirements of aluminum parts paint film). The hot airflow directly acts on the surface of the winding wheel that has just been painted, so that the paint film can be cured quickly, avoiding scratches or drips in the paint film during the rolling process, and further ensuring the coating quality.

[0017] The illustrative embodiments and descriptions of the present invention are provided herein to explain the invention, but are not intended to limit the invention.

[0018] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0019] It should be understood that the terms "comprising / including," "consisting of," or any other variations are intended to cover non-exclusive inclusion, such that a product, apparatus, process, or method that comprises a list of elements includes not only those elements but may also include, where necessary, other elements not expressly listed, or elements inherent to such a product, apparatus, process, or method. Without further limitation, an element defined by the phrases "comprising / including," "consisting of," does not exclude the presence of additional identical elements in the product, apparatus, process, or method that includes said element.

[0020] It should also be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device, component or structure referred to must have a specific orientation, be constructed or operated in a specific orientation, and should not be construed as a limitation of the present invention.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] like Figures 1-3 As shown, an automatic painting device for an aluminum winding wheel for industrial doors includes an inclined plate 1, a vertical plate 2 fixedly installed at the rear end of the inclined plate 1, a top plate 3 fixedly installed at the top end of the vertical plate 2, a paint spray box 4 fixedly installed at the upper end of the top plate 3, an inlet pipe 9 connected to the upper end of the paint spray box 4, a conduit 10 connected to the lower end of the paint spray box 4 through the top plate 3, a diversion pipe 11 fixedly installed at the lower end of the conduit 10, and a spray pipe 12 connected to the outside of the diversion pipe 11.

[0023] In this embodiment, a fixed slide rail groove 6 is fixedly installed on the upper end of the inclined plate 1, and a sliding slide rail groove 7 is provided on the upper end of the inclined plate 1.

[0024] In this embodiment, a fixing block 8 is fixedly installed on the outside of the sliding slide rail groove 7, and a bolt passes through the upper end of the fixing block 8.

[0025] In this embodiment, a drying box 5 is fixedly installed on the upper end of the top plate 3, and a metal mesh 13 is fixedly installed on the upper end of the drying box 5.

[0026] In this embodiment, a blower 14 is fixedly installed inside the drying oven 5, and the air outlet of the blower 14 is connected to an air duct 15.

[0027] In this embodiment, the air duct 15 passes through the bottom of the top plate 3, and a heating rod 16 is fixedly installed inside the air duct 15.

[0028] The implementation principle of an automatic painting device for an aluminum winding wheel of an industrial door according to an embodiment of this application is as follows: the paint spray box 4 continuously receives external paint through the liquid inlet pipe 9. After being internally pressurized, the paint is transported to the distribution pipe 11 through the conduit 10. The distribution pipe 11 evenly distributes the paint to multiple sets of spray pipes 12 arranged along the length of the slide rail groove. The nozzles of the spray pipes 12 atomize the paint into fine particles (the atomization efficiency is much higher than that of manual spraying), and the nozzle orientation is perpendicular to the rolling trajectory of the winding wheel to ensure that the atomized paint can vertically cover the surface of the winding wheel. Because the winding wheel is in a uniform rolling state, all areas of its surface (including the depth of the annular groove and the corners of the spoke connection) will pass through the spraying range of the spray pipe 12 in sequence. Every time the winding wheel rolls once, all areas of the surface can be covered by atomized paint. At the same time, the distance between the two sets of slide rails is precisely adjusted to support only the rim of the winding wheel, while the cylindrical surface, groove surface and other key areas of the winding wheel are fully exposed, avoiding the slide rails from obstructing the paint spraying and completely solving the problem of "groove missed coating" in traditional manual spraying. The paint output pressure of the paint box 4 remains stable (which can be adjusted by the valve of the inlet pipe 9), and the diversion pipe 11 ensures that the paint flow rate of each set of spray pipes 12 is consistent. Combined with the uniform rolling speed of the winding wheel (controlled by the tilt angle of the inclined plate 1 and the friction coefficient of the slide rail), a paint film of uniform thickness is formed on the surface of the winding wheel (the thickness deviation can be controlled within 5%), eliminating the need for subsequent manual polishing and repair. After the winding wheel is painted, it continues to roll along the slide rail to the lower end of the inclined plate 1 (below the drying system). At this time, the drying box 5 starts simultaneously: the blower 14 draws in external air and delivers it to the area below the top plate 3 through the air duct 15; the heating rod 16 inside the air duct 15 heats the airflow to the set temperature (usually 60-80℃, suitable for the curing requirements of aluminum parts). The hot airflow acts directly on the surface of the winding wheel that has just been painted, so that the paint film can be cured quickly, avoiding scratches or drips in the paint film during the rolling process, and further ensuring the coating quality.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.
