Description

Technical Field

[0001] This utility model belongs to the field of strip steel processing technology, specifically relating to a continuous oiling equipment for galvanized strip steel. Background Technology

[0002] Galvanized steel strip is coated with rust-preventive oil using an oiling machine. After the oil solidifies, it provides the galvanized steel strip with excellent rust prevention and stamping properties. The steel strip is conveyed from its end by a roller conveyor structure. During this process, the oil is sprayed directly onto the steel strip surface from above by the oiling rack on the oiling machine. The oil gradually solidifies on the surface during transport. However, the steel strip vibrates during transport, causing the oil to shift across the surface as it passes the oiling rack. This affects the coverage of the oil and the uniformity of the coating, thus impacting the oiling effect and reducing work efficiency. Utility Model Content

[0020] In this embodiment: the outer shell 2 is located outside the oiler 1. The outer shell 2 consists of a fixed shell 21 and a baffle shell 22. The baffle shell 22 is fixedly connected between the two fixed shells 21. The oiler 1 is fixedly connected inside the fixed shell 21 at the front position. The spray gun 11 is fixed to the side of the oiler 1. The spray gun 11 is located inside the baffle shell 22. The oiler 1 and the spray gun 11 are stably positioned and connected inside the outer shell 2. The outer shell 2 effectively shields and protects the oiler 1 and the spray gun 11 from the outside. The oiler 1 is activated to spray oil onto the surface of the conveyed steel strip through the spray gun 11.

[0021] The material guiding assembly 3 is located inside the outer shell 2. The material guiding assembly 3 consists of a horizontal plate 31, pressure blocks 32, and side blocks 33. The horizontal plate 31 is fixedly connected to the inner wall of the outer shell 21. Two pressure blocks 32 are fixedly connected to the top two ends of the horizontal plate 31, and two side blocks 33 are symmetrically fixedly connected to the top of the horizontal plate 31. The two ends of the side blocks 33 contact the two pressure blocks 32. The horizontal plate 31 stably positions the two pressure blocks 32 and the two side blocks 33 inside the outer shell 2. The horizontal plate 31 supports the conveying strip steel below the spray frame 11. The horizontal plate 31 supports the conveying strip steel from below, and the two pressure blocks 32 at the top of the horizontal plate 31 press and constrain the strip steel from above. The two side blocks 33 block and constrain the strip steel from both sides. The horizontal plate 31, the two pressure blocks 32, and the two side blocks 33 work together to constrain and guide the strip steel from above and from the sides, allowing the strip steel to be conveyed stably and in a straight line through the area where the spray frame 11 is located.

[0022] The pressure adjustment assembly 4 is located above the horizontal plate 31. The pressure adjustment assembly 4 consists of a fixed frame 41, pressure rollers 42 and smoothing rollers 43. The fixed frame 41 is fixedly connected to the top of the horizontal plate 31. A connecting frame 44 is fixedly connected to the front side wall of the fixed frame 41. The two pressure rollers 42 are fixed to the inner side of the connecting frame 44, one in front and one behind. A positioning frame 45 is fixedly connected to the rear side wall of the fixed frame 41. The smoothing rollers 43 are rotatably connected to the inner side of the positioning frame 45. The fixed frame 41 stably positions the two pressure rollers 42 and the smoothing rollers 43 from front to back on the front and rear sides of the spray gun 11. The conveyed strip passes through the pressure block 32 at the front end of the horizontal plate 31 and gradually approaches the spray gun 11. The pressure roller 42 and the smoothing roller 43 are both located between the two side blocks 33. The pressure roller 42 and the smoothing roller 43 are flush, so that the pressure roller 42 can contact the surface of the strip from above. The two pressure rollers 42 press the strip from above in sequence before the strip approaches the spray gun 11. The two pressure rollers 42 continuously press the conveyed strip, which can effectively plan an independent area for pressing and adjusting the strip before it approaches the spray gun 11, avoiding the strip from shaking or shifting during the process of passing through the spray gun 11, and allowing the strip to be conveyed smoothly towards the spray gun 11. After being sprayed with oil by the spray gun 11, the strip steel continues to be conveyed, gradually approaching the smoothing roller 43. The smoothing roller 43 contacts the surface of the strip steel and rolls along the surface, so that the smoothing roller 43 can perform surface oil rolling and smoothing operation on the oil-sprayed strip steel behind the spray gun 11. This can effectively smooth the oil sprayed on the surface of the strip steel, ensure the coverage of the oil on the surface of the strip steel, improve the uniformity of oil spraying, improve the oiling effect of galvanized strip steel, and improve work efficiency.

[0023] The working principle and usage process of this utility model are as follows: Galvanized steel strip is conveyed from the outside of the outer shell 2 to the inside of the outer shell 2. After passing through the pressure block 32 at the front end of the horizontal plate 31, the steel strip moves above the horizontal plate 31. The horizontal plate 31 supports the conveyed steel strip from below, and the pressure block 32 presses and constrains the steel strip from above. Two side blocks 33 block the steel strip from both sides, constraining and guiding the steel strip, keeping it in a straight conveying state to be conveyed to the area where the spray gun 11 is located. The conveyed steel strip approaches the pressure roller 42 located at the front, and the pressure roller 42 contacts the surface of the steel strip from above. Two pressure rollers 42 continuously press and tighten the conveyed strip steel, one in front of the other. Before the strip steel approaches the spray gun 11, an independent area is designated for pressing and adjusting the strip steel, allowing it to be smoothly conveyed towards the spray gun 11. The oiler 1 is activated to spray oil onto the surface of the strip steel through the spray gun 11. After the strip steel is sprayed with oil through the spray gun 11, it continues to be conveyed. The strip steel gradually approaches the smoothing roller 43. The smoothing roller 43 contacts the surface of the strip steel and rolls along the surface of the strip steel to smooth the oil sprayed on the surface of the strip steel. The adjusted strip steel is removed from the inside of the outer shell 2 and continues to be conveyed.
