Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a sheet metal spraying heating mechanism. Background Art

[0002] Spraying is an important process in the sheet metal industry. It has two main purposes. The first is to increase the anti-rust, anti-corrosion and sealing capabilities and improve the service life in harsh environments. The second is to obtain the required surface effects, such as aesthetics, smoothness, touch feel, anti-fingerprint, waterproof performance, etc. Good surface treatment capabilities are one of the core competitiveness of sheet metal companies.

[0003] After spraying, the natural drying method is adopted. Dust will fall on the surface of the sprayed material, which is difficult to clean. In addition, the surface of the dried material is prone to blistering, and the quality is poor. Sometimes, the surface of the material after spraying needs to be dried and heated.

[0004] It has been found in actual use that the existing heating methods for sheet metal spraying have the following shortcomings:

[0005] Drying time and temperature will have a significant impact on the quality of the paint surface. Since the workpiece has many sides, the existing drying and heating device can only dry one side at a time. Drying the flat surface is prone to dead corners, resulting in wrinkles, bubbles and cracks on the paint surface.

[0006] In addition, the drying time is difficult to control. If the drying time of one side of the workpiece is too long, the paint surface may lose its gloss or change color, affecting the quality of the paint surface and failing to achieve the desired effect.

[0007] Therefore, the present application provides a sheet metal spray heating mechanism to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 A sheet metal spray heating mechanism is shown in an embodiment of the utility model, comprising: a heating box 1, a box door 2, a handle 3, a fixing frame 4, an axle seat 5, a fixing seat 6, a far-infrared heating tube 7, a layer frame splint 8, a placement rack 9 and a transmission motor 10. The box door 2 is installed on the front of the heating box 1, and the handle 3 is installed on the box door 2. The fixing frame 4 is installed inside the heating box 1, and a placement groove 401 is arranged inside the fixing frame 4. The axle seat 5 is installed on the right side of the fixing frame 4, and the fixing seat 6 is installed inside the fixing frame 4. The far-infrared heating tube 7 is installed on the inner side of the fixing seat 6. The layer frame splint 8 is installed on the right side of the heating box 1, and the placement rack 9 is installed on the inner side of the layer frame splint 8. The transmission motor 10 is installed at the left outer end of the heating box 1.

[0030] In this embodiment, the fixing frame 4 is cylindrical and is transversely installed inside the heating box 1 . The cylindrical fixing frame 4 can evenly surround the outer end of the placement frame 9 after rotation.

[0031] In this embodiment, two groups of rectangular openings are provided on the front of the fixing frame 4, and a circular opening is provided on the right side of the fixing frame 4. The rectangular openings provided on the front of the fixing frame 4 facilitate the placement and removal of the placement frame 9 and the sheet metal parts that need to be heated.

[0032] In this embodiment, the transmission shaft of the transmission motor 10 passes through the inner wall of the heating box 1 and is connected to the shaft seat 5. After the transmission motor 10 is working, the transmission shaft drives the shaft seat 5 and the fixing frame 4 to rotate.

[0033] In this embodiment, a plurality of groups of fixing seats 6 and far-infrared heating tubes 7 are arranged inside the fixing frame 4, and the plurality of groups of fixing seats 6 and far-infrared heating tubes 7 are arranged around the inner wall of the fixing frame 4. The far-infrared heating tubes 7 utilize their own far-infrared radiation heating to heat around the outer end of the placement frame 9. The evaporation of moisture and solvent inside will not cause bubbles and small holes in the surface of the dried paint layer, which can effectively improve the surface quality of the paint.

[0034] In this embodiment, the shelf clamp 8 passes through the right side opening of the fixed frame 4 and extends to the interior of the fixed frame 4, and the width of the shelf clamp 8 is smaller than the inner diameter of the fixed frame 4, which is convenient for removing the placement rack 9 on the shelf clamp 8 from the right side opening of the fixed frame 4. The fixed frame 4 will not contact the shelf clamp 8 when rotating, thereby preventing the shelf clamp 8 from affecting the rotation of the fixed frame 4.

[0035] In this embodiment, the shelf clamp 8 is in a "concave" shape, one end of the placement rack 9 is embedded in the inner groove of the shelf clamp 8, the placement rack 9 is located on the inner side of the rectangular opening of the fixed frame 4, and the placement rack 9 can be moved out from the outside of the shelf clamp 8, so that the placement rack 9 can be easily disassembled and assembled.

[0036] In this embodiment, the placement rack 9 is arranged horizontally, and the placement rack 9 extends horizontally to the left side of the fixing rack 4, and the axes of the placement rack 9 and the fixing rack 4 are on the same axis. When heating, the workpiece is placed on the placement rack 9, the box door 2 is closed, and the transmission motor 10 is started. After the transmission motor 10 works, it drives the shaft seat 5 and the fixing rack 4 to rotate through the transmission shaft. The far-infrared heating tube 7 surrounding the inner wall of the fixing rack 4 can move in a circle around the placement rack 9, thereby ensuring uniform heating of the workpiece, effectively eliminating the heating dead corners of the workpiece, and making the paint film forming more uniform.
