Technical Field
[0001] This utility model relates to the field of hot-dip galvanized steel strip, specifically a straightening device for hot-dip galvanized steel strip. Background Technology
[0002] Hot-dip galvanized steel strip is steel strip that has undergone special processing. It is made by immersing the steel strip in a molten zinc bath, and a uniform zinc layer is formed on the surface of the steel strip through a chemical reaction to provide corrosion protection. During processing, such as rolling, cooling, transportation or other processing, it is prone to bending and needs to be straightened.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0018] Combination Figures 1-4 A straightening device for hot-dip galvanized steel strip includes a base plate 1. Two adjusting frames 2 are fixedly installed on the top of the base plate 1 near the front and rear ends. Two transmission rollers 3 are movably installed inside each of the two adjusting frames 2. Two sets of pressure rollers 4 are movably installed on the top of the base plate 1 near the middle. Three balancing components 5 are installed on the top of the base plate 1. Anti-deviation components 6 are installed on the top of the base plate 1 near the front and rear ends.
[0019] See Figure 2 and Figure 3 Furthermore, the balancing assembly 5 includes a set of crossbars 7. Two of the crossbars 7 are fixedly installed directly above the base plate 1. Three positioning seats 8 are fixedly installed at the bottom of the upper crossbar 7 and the top of the lower crossbar 7. Inclined surfaces 9 are provided at the front and rear ends of the positioning seats 8. A limiting groove 11 is provided at the bottom of the positioning seat 8. Several rotating rollers 10 are movably installed inside the limiting groove 11. The thickness of cold-rolled strip steel is generally 0.05-3.6 mm, and the thickness of hot-rolled strip steel is usually 1.2-8 mm. The pressure of the transmission roller 3 is adjusted by the adjusting frame 2.
[0020] The three sets of crossbars 7 are located between the two sets of pressure rollers 4 and the drive rollers 3 respectively. The crossbars 7 located between the upper and lower ends are symmetrically installed. There are two crossbars 7 in each set, and the two crossbars 7 in each set are located at the top and bottom of the strip steel respectively.
[0021] The three positioning seats 8 are arranged at equal intervals, and there is a gap between the two positioning seats 8 located at the upper and lower ends. The positioning seats 8 are used to balance the two sides of the strip steel, and the curved strip steel is allowed to enter between the corresponding two positioning seats 8 through the inclined surface 9.
[0022] The two inclined surfaces 9 are symmetrically arranged, and the rotating roller 10 is located in the limiting groove 11 and is movably rotating. The rotating roller 10 contacts the surface of the strip and rotates to reduce the friction of the strip.
[0023] Specifically, the strip passes between two drive rollers 3 and two corresponding pressure rollers 4. When passing through the gap between the drive rollers 3 and the pressure rollers 4, one end of the strip bends and passes through the inclined surface 9 between the two corresponding positioning seats 8. The rotating roller 10 contacts the surface of the strip and reduces friction by rotating the roller 10. Example
[0024] See Figure 4 Furthermore, based on Embodiment 1, the anti-deviation component 6 includes an adjustment seat 12. Two adjustment seats 12 are fixedly installed on the top of the base plate 1 near the front and rear ends, respectively. A screw 13 is movably installed inside the adjustment seat 12. A slider 14 is connected to the outside of the screw 13. A positioning plate 15 is fixedly installed on the top of the slider 14. A rocker plate 16 is installed on one end of the screw 13.
[0025] The screw 13 is fixedly connected to the rotating shaft of the rocker plate 16. By rocking the rocker plate 16, the screw 13 is driven to rotate.
[0026] The slider 14 is located outside the screw 13 and is connected by a thread. The screw 13 drives the slider 14 to slide, and the positioning plate 15 positions the outer side of the strip.
[0027] Specifically, the screw 13 drives the slider 14 to slide, and the distance between the positioning plate 15 and the other side is adjusted to match the width of the strip. The positioning plate 15 positions the strip to prevent it from shifting during the conveying and straightening process.
[0028] In actual operation, the strip passes between the two drive rollers 3 located at the rear end, and is continuously straightened by two sets of pressure rollers 4, and is then conveyed out by the two drive rollers 3 located at the front end. During the balancing and straightening process, the strip passes between two drive rollers 3 and two corresponding pressure rollers 4. When passing through the gap between the drive rollers 3 and the pressure rollers 4, one end of the strip bends and passes through the inclined surface 9 between the two corresponding positioning seats 8. The rotating roller 10 contacts the surface of the strip and reduces friction by rotating the roller 10. When adjusting for deviation, the screw 13 is rotated by shaking the rocker 16. The screw 13 drives the slider 14 to slide under the action of the thread, adjusting the position of the positioning plate 15 and the distance on the other side to match the width of the strip. The positioning plate 15 is used to position the feed inlet and outlet of the strip to prevent deviation during the conveying and straightening process.
[0029] By setting the balancing component 5, the strip is positioned between the two positioning seats 8. The inclined surface 9 allows the strip to enter, preventing it from bending and detaching from the pressure roller 4 during continuous straightening. The rotation of the rotating roller 10 reduces friction on the strip surface. By setting the anti-deviation component 6, the screw 13 drives the slider 14 to slide, changing the distance between the positioning plate 15 and the other side. The positioning plate 15 prevents the strip from shifting during conveying and straightening, and facilitates adjustment of the positioning width.
