Description

Technical Field

[0001] This application relates to the field of oxygen-free copper strip processing technology, specifically to a hot-rolled surface treatment device for oxygen-free copper strip. Background Technology

[0002] In the hot rolling process of copper strip, the removal of surface oxide scale is a crucial step affecting product quality and subsequent processing performance. Oxygen-free copper, due to its high conductivity and good processing performance, is widely used in electronics, power, and communications fields. However, during hot rolling, the surface of copper strip is prone to oxidation at high temperatures, forming oxide scale. If this scale is not removed promptly and effectively, it not only affects the surface finish of the copper strip but may also lead to defects such as cracks and delamination in subsequent processing, reducing the mechanical and electrical properties of the product.

[0003] Currently, while mechanical cleaning methods such as scrapers and brush rollers can achieve a certain degree of cleaning of the oxide scale on the surface of copper strips, they are prone to causing scratches on the copper strip surface. Chemical cleaning, on the other hand, faces problems such as high environmental pressure and complex processes. Traditional high-pressure gas purging methods, due to the fixed position of the air knife and the inability to adjust the purging angle and height, have limited cleaning effects and cannot meet the production requirements of high-precision, high-quality copper strips. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide a hot rolling surface treatment device for oxygen-free copper strip, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a hot-rolled surface treatment device for oxygen-free copper strip, comprising a support base, a drive motor mounted on the support base, a drive sprocket mounted on the output end of the drive motor, a pressure roller connected to the drive sprocket, a side support base mounted on the upper end of the pressure roller, an upper support plate mounted on the upper surface of the side support base, a sliding groove mounted on the upper support plate, a side support plate mounted on the sliding groove, an air knife assembly mounted between the side support plates, a lifting adjustment component mounted at the middle position of the upper surface of the upper support plate, a limit plate connected to the telescopic end of the lifting adjustment component, the limit plate being connected to the side support plates via a right-angle plate, the air knife assembly comprising a support plate and a high-pressure air gun, the support plate being mounted between the side support plates, and the high-pressure air gun being linearly mounted within a through hole on the support plate and fixed to the support plate by a locking component.

[0010] As a preferred technical solution of this application, a through hole is provided on one side of the side support plate, and the pivot at the end of the support plate is rotatably connected to the through hole of the side support plate.

[0011] As a preferred technical solution of this application, the rear end of the support plate is provided with a hinge seat, and the hinge seat is provided with a hinge shaft, which passes through the limiting plate and is screwed to the adapter sleeve.

[0012] As a preferred technical solution of this application, a positioning plate is provided at the upper end of the side frame support plate, and the positioning plate corresponds to the slot on the side support.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: This application, through a lifting adjustment component mounted on the upper support plate, allows for flexible adjustment of the height position of the air knife assembly, making it adaptable to cleaning operations on copper strip surfaces of different thicknesses or with different process requirements, thereby improving cleaning efficiency and applicability.

[0020] Example 1, see Figure 1 and 2 A hot rolling surface treatment device for oxygen-free copper strip includes a support base 4, on which a drive motor 3 is mounted. The output end of the drive motor 3 is provided with a drive sprocket 10. The drive sprocket 10 is connected to a pressure roller section 8. The lower end of the pressure roller in the pressure roller section 8 is provided with a driven sprocket 11. The driven sprocket 11 and the drive sprocket 10 are connected by a chain.

[0021] The power transmission assembly in this application transmits the power of the drive motor 3 to the pressure roller section 8 via a chain, driven sprocket 11, and drive sprocket 10.

[0022] More specifically, the upper and lower pressure rollers in the pressure roller section 8 are both equipped with gears 12 that mesh with each other. During the rotation of the driven sprocket 11, the meshing gears 12 are driven to rotate, thereby realizing the rotation of the upper and lower pressure rollers.

[0023] The pressure roller section 8 includes a side frame support plate 9 and a pressure roller assembly. The pressure roller assembly is disposed between the side frame support plates 9, and the side frame support plates 9 are symmetrically disposed on the upper surface of the support base 4 to ensure the stability of the pressure roller section 8 during operation.

[0024] The upper end of the pressure roller section 8 is provided with a side support 7, the upper surface of the side support 7 is provided with an upper support plate 6, the upper support plate 6 is provided with a sliding groove, and the sliding groove is provided with a side support plate 14.

[0025] In order to make the side support plate 14 more stably set in the slide groove, a clamping plate is installed at the corresponding position of the slide groove to limit the side support plate 14 and prevent it from leaving the slide groove.

[0026] A wind knife assembly is provided between the side support plates 14. A lifting adjustment component 15 is provided at the middle position of the upper surface of the upper support plate 6. The telescopic end of the lifting adjustment component 15 is connected to a limit plate 13. The limit plate 13 is connected to the side support plate 14 through a right-angle plate. The wind knife assembly includes a support plate 17 and a high-pressure air gun. The support plate 17 is provided between the side support plates 14. The high-pressure air gun is linearly provided in the through hole on the support plate 17 and is fixed to the support plate 17 by a locking component.

[0027] Waste collection hoppers 2 are provided between the side frame support plates 9.

[0028] In this embodiment, the drive motor 3 starts, the active sprocket 10 starts, and the power is transmitted to the driven sprocket 11 through the chain. The upper and lower pressure rollers in the pressure roller section 8 are equipped with meshing gears 12, which drive the pressure roller section 8 to rotate to achieve rolling. During the rolling process, the height of the air knife assembly is adjusted by the extension and shortening of the lifting adjustment component 15, so that the air knife assembly can clean the oxide scale on the surface of the copper plate and improve the quality of the product surface.

[0029] Example 2, see Figure 1 , Figure 2 , Figure 3 and Figure 4 A hot-rolled surface treatment device for oxygen-free copper strip is further optimized in Embodiment 1. A through hole is provided on one side of the side support plate 14. The rotating shaft at the end of the support plate 17 is rotatably connected to the through hole of the side support plate 14. A hinge seat 16 is provided at the rear end of the support plate 17. A hinge rotating shaft 18 is provided in the hinge seat 16. The hinge rotating shaft 18 passes through the limiting plate 13 and is screwed to the adapter sleeve.

[0030] Because the pivot at the end of the support plate is connected to a through hole on one side of the side support plate 14, the above structure constitutes a relatively rotating component, which allows the angle of the support plate to be adjusted, and thus the angle of the air knife assembly.

[0031] Specifically, the outer side of the rotating shaft is threaded, and the inner diameter of the through hole of the side support plate 14 is larger than the inner diameter of the rotating shaft. When adjusting the angle, the adapter sleeve rotates, the position of the side support plate 14 remains unchanged, and the rotating shaft is extended or shortened by the adapter sleeve, thereby achieving the angle adjustment.

[0032] By combining the height adjustment in Example 1, the airflow direction can be adjusted more precisely, further improving the cleanliness of the board surface and enhancing product quality.

[0033] The upper end of the side frame support plate 9 is provided with a positioning plate, which corresponds to the slot on the side support 7.

[0034] The use of positioning plates improves the installation efficiency and accuracy of the side support 7, and enhances the ease of assembly.

[0035] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
