Description

Technical Field

[0001] The utility model relates to the field of steel pipe production, in particular to a device for painting color rings on steel pipes. Background Art

[0002] In the finishing production of steel pipes, there is a process called painting color rings. At one end of the steel pipe Figure 1 a color ring is painted. For some types of steel pipes, color rings need to be painted at the pipe ends. However, some manufacturers only have a length measuring, weighing and spraying marking device and do not have a color ring painting device. In order to meet the requirements of users, the manufacturers can only send workers to paint with brushes, which wastes labor and paint materials, and the painting quality is also not good.

[0003] For the disclosed patent (CN 202479102 U), a steel pipe color ring painting device includes: an inclined platform frame, with a rectangular groove body on one side of the inclined platform frame, and a sponge body on the inner surface of the rectangular groove body. Or there is a rectangular groove body on the upper surface of the inclined platform frame, and a sponge body on the inner surface of the rectangular groove body. The utility model has a simple structure, extremely low cost, good painting quality and is easy to maintain. However, it cannot automatically add paint (colored paint), which brings certain inconvenience to use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for painting color rings on steel pipes, which has a simple structure, extremely low cost, good painting quality, is easy to maintain, and can automatically replenish paint.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A device for painting color rings on steel pipes of the utility model includes: an inclined platform frame, with a bracket on one side of the inclined platform frame. Above the bracket, there is a "day"-shaped groove body. At the end of the right side of the "day"-shaped groove body close to the inclined platform frame, there is a rectangular groove body. The width of the rectangular groove body is 20 mm - 25 mm, and a sponge body is provided on its inner surface. The upper surface of the sponge body is 5 mm - 10 mm higher than the upper surface of the rectangular groove body;

[0007] The "day"-shaped groove body is composed of a left rectangular body groove and a right rectangular body groove. There are a plurality of through holes on the middle partition plate between the two grooves, so that the paint liquid in the two rectangular groove bodies can flow freely, and it is also convenient for the paint to penetrate into the sponge body;

[0008] On the left side of the "day"-shaped groove body, there is a platform frame. On the upper part of the platform frame, there is a paint bucket. The bottom of the paint bucket is 20 cm - 30 cm higher than the upper surface of the "day"-shaped groove body. There is a pipeline at the lower part of the paint bucket, and the opening surface at the end of the pipeline is vertically downward and is 2 mm - 5 mm lower than the upper surface of the "day"-shaped groove body;

[0009] The upper surface of the "day"-shaped groove body is on the same plane as the top of the inclined platform frame;

[0010] The paint bucket, the bench, and the pipeline do not interfere with the rolling track of the steel pipe.

[0011] Furthermore, the width of the rectangular groove body is 20 mm.

[0012] Furthermore, the width of the rectangular groove body is 25 mm.

[0013] Furthermore, the bottom of the paint bucket is 20 cm, 25 cm, or 30 cm higher than the upper surface of the "day"-shaped groove body.

[0014] Furthermore, the opening surface at the end of the pipeline is 2 mm, 3 mm, 4 mm, or 5 mm lower than the upper surface of the "day"-shaped groove body.

[0015] Furthermore, a control valve is also arranged on the pipeline.

[0016] A method for using a device for painting color rings on steel pipes includes:

[0017] During production, the steel pipe rolls on the inclined bench, and the end of the steel pipe passes through the sponge body with paint, so that a color ring meeting the standard requirements is painted on one circle of the end of the steel pipe;

[0018] When the paint liquid level in the "day"-shaped groove body drops below the opening surface at the end of the pipeline, the paint in the paint bucket flows into the "day"-shaped groove body through the pipeline. When the paint liquid level in the "day"-shaped groove body rises above the opening surface at the end of the pipeline, the paint in the paint bucket stops flowing into the "day"-shaped groove body under the action of the atmospheric pressure.

[0019] Compared with the prior art, the beneficial technical effects of the present utility model are:

[0020] When the paint liquid level in the "day"-shaped groove body drops below the opening surface at the end of the pipeline, the paint in the paint bucket flows into the "day"-shaped groove body through the pipeline. When the paint liquid level in the "day"-shaped groove body rises above the opening surface at the end of the pipeline, the paint in the paint bucket stops flowing into the "day"-shaped groove body under the action of the atmospheric pressure. The automatic addition of paint is realized, and the convenience of using the device for painting color rings on steel pipes is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] As Figure 1 and 2 shown, a device for painting color rings on steel pipes includes: an inclined platform frame 2, with a support on one side of the inclined platform frame 2, and an H-shaped trough body 3 above the support. The width of the rectangular trough on the right side of the H-shaped trough body 3 close to the inclined platform frame 2 is 20 mm - 25 mm, and a sponge body 4 is arranged inside it. The upper surface of the sponge body 4 is 5 mm - 10 mm higher than the upper surface of the rectangular trough on the right side of the H-shaped trough body 3 close to the inclined platform frame 2;

[0026] The H-shaped trough body 3 is composed of a left rectangular trough and a right rectangular trough. Multiple through holes are arranged on the partition between the two troughs so that the paint liquid in the two rectangular troughs can flow freely, and it is also convenient for the paint to soak into the sponge body;

[0027] A platform frame 7 is arranged on the left side of the H-shaped trough body 3, and a paint bucket 6 is arranged on the upper part of the platform frame 7. The bottom of the paint bucket 6 is 20 cm - 30 cm higher than the upper surface of the H-shaped trough body 3. A pipeline 5 is arranged below the paint bucket 6, and the end opening of the pipeline 5 faces downward, and the opening surface is 2 mm - 5 mm lower than the upper surface of the H-shaped trough body 3;

[0028] The upper surface of the H-shaped trough body 3 is on the same plane as the top of the inclined platform frame 2;

[0029] The paint bucket 6, the support 7, and the pipeline 5 do not interfere with the rolling track of the steel pipe.

[0030] Its usage method is as follows:

[0031] During production, the steel pipe 1 rolls on the inclined platform frame, and the end of the steel pipe passes through the sponge body with paint, and a color ring that meets the standard requirements is painted on the circumference of the end of the steel pipe. When the paint liquid level in the H-shaped trough body 3 drops below the end opening surface of the pipeline 5, the paint in the paint bucket 6 flows into the H-shaped trough body 3 through the pipeline 5. When the paint liquid level in the H-shaped trough body 3 rises above the end opening surface of the pipeline 5, the paint in the paint bucket 6 stops flowing into the H-shaped trough body 3 under the action of atmospheric pressure.

[0032] The above-described embodiments are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
