[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Example: Reference Figure 1 , Figure 2 A correction mechanism for strip steel processing shown in the figure comprises a pair of conveying rollers 1 and a pair of conveying rollers 2 for conveying the strip steel, both ends of the conveying rollers 1 and 2 are installed with the same alignment seat 4, and the pair of conveying rollers 2 2 are parallelly distributed obliquely above the pair of conveying rollers 1.
[0021] A lifting and lowering straightening rod 3 is arranged inside the relative space of a pair of conveyor rollers 2. The straightening rod 3 is located just above the gap between the pair of conveyor rollers 1. When the rolled steel strip is conveyed to just below the straightening rod 3 by the conveyor rollers 1 and 2 located on one side of the straightening rod 3, the steel strip has been subjected to pressure processing by the conveyor rollers 1 and 2, which can reduce the curvature of the steel strip surface. Subsequently, the straightening rod 3 descends and presses against the surface of the steel strip. The straightening rod 3 further flattens the steel strip after the first round of flattening operation, driving the arc surface of the steel strip after the curvature is reduced to be flattened. Subsequently, the steel strip can pass through the surface of the conveyor rollers 1 and 2 on the other side in turn. The conveyor rollers 1 and 2 on this side can perform another pressure processing on the steel strip, which improves the flattening effect.
[0022] Both ends of the correction rod 3 are equipped with follower seats 31 that can rise and fall synchronously with it. The follower seats 31 are located on the inner side of the alignment seat 4. The upper surface of the alignment seat 4 is equipped with a cylinder 32. The push rod set at the output end of the cylinder 32 penetrates the upper surface of the alignment seat 4 and is installed on the upper surface of the correction rod 3. When the cylinder 32 is in operation, the push rod at its output end continuously extends and retracts, thereby driving the follower seat 31 and the correction rod 3 to rise and fall. The correction rod 3 can flatten the surface of the strip, eliminate the bending shape of the strip produced in the long-term winding state, and improve the flatness of the strip during the transmission process.
[0023] like Figure 1 As shown, both sides of the follower seat 31 are connected with extension arms 33 by screws, and a pair of guide rods 34 are installed on the inner side of the alignment seat 4. The guide rods 34 are all through the extension arms 33. When the follower seat 31 and the correction rod 3 move synchronously, the extension arms 33 move synchronously along the direction of the guide rods 34. The connection between the extension arms 33 and the guide rods 34 can maintain the accuracy of the follower seat 31 and the correction rod 3 during the movement of the rise and fall, effectively avoid the shaking and deviation of the correction rod 3, and further improve the stability of the correction rod 3.
[0024] like Figure 3 As shown, a pair of conveying rollers 1 located in the same horizontal plane are respectively installed with driven gears 11 at their ends, and the pair of driven gears 11 are meshedly connected with the same driven gear 2 12, and the driven gear 11 located on one side is meshedly connected with a linkage gear 13, and a servo motor 14 matched with the linkage gear 13 is installed on one side. In a natural state, when the servo motor 14 is running, the driven gear 11 meshed with the linkage gear 13 rotates. Since the pair of driven gears 11 are meshedly connected with the same driven gear 2 12, the pair of driven gears 11 can be driven to rotate in the same direction, thereby ensuring the smooth transmission of the strip above them.
[0025] like Figure 3 As shown, one end of the conveying roller 2 is equipped with a servo motor 21 adapted thereto, and the outer surface of the conveying roller 2 and near both ends are equipped with a limit shaft seat 22, which is installed on the side surface of the alignment seat 4. The limit shaft seat 22 can maintain the stability of the conveying roller 2 in the running state and has a supporting effect on it.
[0026] like Figure 4 As shown, the bottom of a pair of alignment seats 4 is installed with the same base 5, the servo motor 14 is installed on the upper surface of the base 5, and the conveying roller 1, the conveying roller 2, and the correction rod 3 are all located above the base 5. The base 5 can maintain the stability of the entire correction mechanism and is suitable for the working environment of long-term transmission and processing of strip steel.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
