Description

Technical Field

[0001] This utility model relates to the field of metal parts conveying technology, and in particular to a roller conveying device for spraying oil onto metal parts. Background Technology

[0002] Cylindrical roller conveyors are versatile and can transport various items with flat bottoms, such as plates, pallets, and boxes. Energy storage devices contain multiple metal parts with flat bottoms, which are typically transported using cylindrical roller conveyors. These metal parts require 7-10 days of storage and turnover from production to final assembly. During this period, to ensure rust prevention without affecting subsequent welding, painting, and sandblasting processes, oiling is necessary. Each part requires a uniform oil film of 3 grams per square meter after oiling, without oil accumulation. In actual production, it was found that the oil accumulation on the lower surface of the oiled parts was severe, sometimes even resulting in black oil stains that could not be removed. To address this issue, we improved existing cylindrical roller conveyors and proposed a roller conveyor device for oiling metal parts. Utility Model Content

[0003] The purpose of this invention is to provide a roller conveying device for spraying oil onto metal parts, which can solve the problem of severe oil accumulation on the lower surface of energy storage parts after oil spraying, and even black oil stains adhering to the bottom surface of the parts that cannot be removed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A roller conveying device for spraying oil onto metal parts includes a base frame, a drive roller, a driven roller, a chain, a roller mounting base, a sprocket, and a roller protrusion. The drive roller and the driven roller are rotatably mounted on the base frame via the roller mounting base. Each drive roller and the driven roller is provided with a sprocket. One drive roller drives multiple driven rollers to rotate via the sprocket and the chain. The drive roller is connected to a drive motor via a drive roller shaft, and the drive motor drives the drive roller to rotate. Each drive roller and each driven roller is provided with a roller protrusion.

[0006] In the aforementioned roller conveying device for spraying oil onto metal parts, the roller protrusions are evenly distributed along the axial direction of each driving roller and driven roller.

[0007] In the aforementioned roller conveying device for spraying oil onto metal parts, the protrusions of the rollers surround the outer surface of the rollers.

[0008] This utility model has the following advantages:

[0009] In this invention, a roller protrusion is provided on the roller, which surrounds the outer surface. The roller protrusion is evenly distributed along the roller axis according to the size of the part. The energy storage part to be transported is placed on the roller protrusion. During the oil spraying operation, the lower surface of the part will not accumulate oil or foreign matter after passing through the roller line in the automatic oil spraying state.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] This utility model discloses a roller conveying device for spraying oil onto metal parts, such as... Figure 1 As shown, a drive roller 2 and a driven roller 3 are installed on the base frame 1. There are multiple driven rollers 3, which are evenly distributed on the base frame. A sprocket 7 is installed on both the drive roller 2 and the driven roller 3. The motor drives the drive roller 2 to rotate through the drive roller shaft 6. The drive roller 2 drives multiple driven rollers 3 to rotate through the chain 4 and the sprocket 7. The energy storage components are placed on the rollers and are transported as the rollers rotate.

[0017] This utility model discloses a roller conveying device for spraying oil onto metal parts, such as... Figure 2 As shown, except for the active roller shaft 6 on the active roller 2, the rest of the structure is the same as that of the driven roller 3. Both the active roller 2 and the driven roller 3 are provided with roller protrusions 8. The roller protrusions 8 are evenly distributed along the axial direction of the roller. The spacing is determined according to the size of the conveyed parts. If the size of the conveyed parts is different, it can be achieved by changing rollers with different spacing between the roller protrusions 8.

[0018] This utility model discloses a roller conveying device for spraying oil onto metal parts. The roller protrusion 8 is an annular protrusion surrounding the surface of the roller, and the cross-sectional shape of the protrusion along the vertical plane is as follows: Figure 4As shown, the cross-section is conical, with a narrow annular surface at the top of the cone, less than 2 millimeters wide, to support the parts without damaging them.

[0019] Analysis of the principle of the roller conveyor device for spraying oil onto metal parts in this utility model: Existing cylindrical roller conveyors use cylindrical drums with smooth cylindrical surfaces. When in contact with the parts, the contact point is along the same line as the axial direction. As the roller carrying the parts rotates, the contact point becomes a contact surface. This causes oil stains on the surface of the cylindrical roller to be smeared onto the lower surface of the parts during operation, resulting in oil accumulation and foreign matter adhesion. In this utility model, the roller protrusion 8 reduces the contact area between the parts and the roller during operation, thereby reducing the phenomenon of oil accumulation and oil stain adhesion on the parts.
