Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel strip processing technology, specifically relating to an integrated energy-saving and environmentally friendly production line for bluing, galvanizing, and painting of packaging steel strips. Background Technology
[0002] Packaging steel strapping, also known as strapping or steel banding, is a narrow strip of packaging material with high tensile strength and a certain elongation. It is widely used in the packaging and bundling of products in the steel, construction, non-ferrous metals, glass, and machinery industries. Currently, domestic and international manufacturers of packaging steel strapping typically treat the surface of the steel strapping to prevent corrosion during storage and transportation. Common methods include painting, galvanizing, and bluing. Bluing is the most common process, characterized by its simplicity and low cost, but its disadvantage is poor corrosion resistance. Painting is another commonly used process, offering advantages such as good corrosion resistance, customizable colors, and an aesthetically pleasing surface, but its disadvantages include poor high-temperature resistance and higher cost. Galvanizing provides the best corrosion resistance and a certain degree of wear resistance, with a relatively wide range of adjustable coating thickness, but it is costly and the production process is relatively complex.
[0003] For some small businesses, building a production line for bluing, galvanizing, and painting would be costly and require a huge investment. At the same time, the equipment utilization rate would be low, resulting in high production costs. Summary of the Invention
[0004] To overcome the problems in the background technology, this utility model provides an integrated energy-saving and environmentally friendly production line for bluing, galvanizing, and painting of steel strips for packaging. By integrating the equipment for bluing, galvanizing, and painting into one production line, the equipment at the front and back ends is shared, reducing construction costs and improving the utilization rate of the equipment at both ends. During production, the corresponding equipment (bluing, galvanizing, and painting) can be activated as needed. When galvanizing is required, the motor 44 drives the swing wall 43 to press the steel strip into the galvanizing tank 41 through the pressure roller 45 for galvanizing. When galvanizing is not required, the motor 44 drives the swing wall 43 to lift the pressure roller 45. Under the action of tension, the steel strip rises with the pressure roller 45 to the top of the galvanizing tank 41, and galvanizing is not performed. When switching between galvanizing and non-galvanizing operations, there is no need to cut the steel strip and then thread it. The switching of production modes is convenient, time-saving, and labor-saving.

[0033] Work process:

[0035] Switching between galvanizing and non-galvanizing work: When galvanizing is required, the motor 44 drives the swing wall 43 to press the steel strip into the galvanizing tank 41 through the pressure roller 45 for galvanizing.

Under the action of tension, the steel strip rises with the pressure roller 45 to the top of the galvanizing tank 41, and galvanizing is not performed. When switching between galvanizing and non-galvanizing work, there is no need to cut the steel strip and then thread it. The switching of production mode is convenient, time-saving and labor-saving.
[0036] Steel strip slitting process: The steel strip limiting component 12 limits the steel strip to be slitting to prevent it from deviating and ensure slitting accuracy. The slitting motor 17 drives the fixed roller 14 to rotate, which works in conjunction with the lifting roller 15 to perform slitting. The waste edge material is wound up and recycled by the steel strip edge material winding device 18, reducing the intensity of manual labor.
[0037] Electric heating blueing process: The steel strip passes sequentially around the feed end guide roller 22, the top first guide roller 22, through the electric heating device 23, the guide roller 22 in the cooling tank 24, the top second guide roller 22, and the discharge end guide roller 22.
