Description

Technical Field

[0001] The utility model belongs to the technical field of steel strip compound deviation correction, and in particular relates to a steel strip compound deviation correction control system. Background Art

[0002] With the development of the national economy, the demand for cold-rolled thin plates, galvanized plates and color steel plates in the home appliance industry and the automobile manufacturing industry is increasing. The quality of strip steel products is not the same. In addition to other factors affecting the quality of strip steel products, quality defects of finished strip steel caused in the coiling process, such as uneven edges, misaligned edges, tower shapes, flattened coils, surface scratches, creases on the head of the steel coil, etc., seriously affect the subsequent use of users, causing great economic losses, and are increasingly attracting people's attention. The existing methods for preventing steel strip from deviation are to adjust the tension of the steel strip through a tensioning mechanism, thereby correcting the deviation of the steel strip. However, this method can only correct the deviation of the steel strip appropriately, but when the tensioning mechanism over-tensions the steel strip, it not only fails to limit the deviation of the steel strip, but also easily causes serious tensile deformation of the steel strip.

[0003] To this end, a correction device for steel strip transmission, with announcement number "CN208648314U," relates to the technical field of steel processing equipment and includes a base and two upright frames symmetrically mounted on the base; a first roller and a second roller are mounted on the two upright frames for co-rotating rotation, with both ends of the second roller being able to slide up and down along the upright frames; a mounting base is fixedly mounted on the upper ends of the two upright frames, and a bracket corresponding to the first roller is hingedly provided on each mounting base; a first pushing device is also hingedly mounted on the two mounting bases, and the extended ends of the two first pushing devices are respectively hinged to the two brackets; a pressure roller is mounted on the two brackets for co-rotating rotation to press the first roller. This device not only achieves automatic correction of the steel strip, is easy to operate, and effectively prevents deformation of the steel strip, but also allows the tension of the steel strip, which is wrapped around the first and second rollers, to be adjusted by adjusting the second roller.

[0004] However, for the above-mentioned deviation correction device for steel belt transmission, although the first pushing device on the side where the steel belt deviates is adjusted to push the bracket, so that the end of the first roller presses the side where the steel belt deviates, so that the steel belt can automatically return to the right position when continuing to be conveyed, there are still the following more obvious defects during use: the above-mentioned device can only convey a single layer of steel belt to correct the deviation, and because the position of each steel belt cannot be guaranteed to be stable when the steel belt is conveyed in a double-layer or triple-layer composite manner, it will still cause the problem of deviation of the position of one layer of the steel belt. Utility Model Content

[0019] See also Figure 1-2 The utility model provides a technical solution: a steel strip composite deviation correction control system, comprising:

[0020] The roller bracket 1 has a reel-and-winder A3 installed on its upper end for correcting the deviation of the steel strip conveyed on the upper layer. The reel-and-winder A3 is fixed to a side surface of the upper end of the roller bracket 1 through a hydraulic correction adjustment seat 11. It can compositely convey the steel strip of one layer and control the conveying of the steel strip through the controller in the connected system. The reel-and-winder B4 for conveying the bottom steel strip is installed at the vertical bottom end of the reel-and-winder A3 and at the lower end of the roller bracket 1.

The steel strip conveying end of the reel-and-winder A3 and one side of the reel-and-winder B4 are respectively provided with a centering sensor 5 for inductive correction of the steel strip conveying. The position of the steel strips conveyed on the upper and bottom layers can be detected by inductive detection to ensure that the three steel strips are kept in the same position during composite conveying, and the detection signal is transmitted to the control in real time, so that the controller controls the hydraulic correction component of each layer to perform correction adjustment, or uses a displacement sensor to detect the position of the steel strip in real time;

[0021] A three-axis deviation correction roller 6 is provided on one side of the unwinding and winding machine B4, and is used for conveying the middle layer of steel strip and performing hydraulic automatic deviation correction. The deviation correction is automatically controlled by an externally connected controller without the need for manual work by personnel. An S-shaped composite conveying roller 8 composed of multiple axis rollers is provided in the middle of one side of the unwinding and winding machine A3 and the unwinding and winding machine B4, which is used for composite conveying of three layers of steel strips and can automatically correct the deviation of the upper and bottom steel strips based on the middle layer of steel strip. The steel strip output end of the S-shaped composite conveying roller 8 is provided with a main equipment conveying unit 9 for composite output of three layers of steel strips, which can output the three-layer composite conveyed steel strip, and the main equipment conveying unit 9 is arranged at the composite steel strip output end of the roller bracket 1 through an installation bracket, which is conducive to composite conveying of the steel strip.

[0022] One end of the rotating shaft of the reeling and unwinding machine A3 and the reeling and unwinding machine B4 is provided with a reeling and unwinding roller 10 for unwinding the steel strip, which can unwind two layers of steel strips at the same time and pass through the centering positioning frame 2 for real-time detection of the conveying position. The bottom of the reeling and unwinding machine A3 and the reeling and unwinding machine B4 is equipped with a hydraulic correction adjustment seat 11 for hydraulic correction adjustment of the reeling and unwinding roller 10. The hydraulic correction adjustment seat 11 can be controlled by a controller to correct the conveying position. A centering correction plate 12 is provided on one side of the fixed seat of the hydraulic correction adjustment seat 11. 4 is provided with a fixed frame 7 on one side, and a hydraulic correction adjustment frame 13 is provided at the end of the fixed frame 7, which is used to correct the unwinding roller 10 by controlling the hydraulic correction adjustment frame 13 through the controller to realize automatic correction adjustment of the position of the lower steel strip. A hydraulic positioning frame 14 is provided at the end of the hydraulic correction adjustment frame 13, which can make one of the correction conveying rollers of the three-axis correction roller 6 rotatably installed at the bottom of one side of the upper end of the hydraulic positioning frame 14, and is conducive to adjusting the height of a correction conveying roller, so as to facilitate the adjustment of the tension of the steel strip conveying.

[0023] Two of the three-axis deviation correction rollers 6 are rotatably mounted on the hydraulic deviation correction adjustment frame 13 for horizontal and linear conveying of the middle layer steel strip, and one of the deviation correction rollers is rotatably mounted on the upper end of one side of the hydraulic positioning frame 14, which can adjust the tension of the steel strip during transportation and ensure the position stability of the middle layer steel strip during transportation. The rear side of the roller bracket 1 is provided with a hydraulic station 15 for driving the unwinding and rewinding machine A3, the unwinding and rewinding machine B4 and the three-axis deviation correction roller 6 for hydraulic deviation correction in the conveying steel strip, which can be used in the deviation correction work. The hydraulic station 15 is controlled by a system-heavy controller to provide power to the hydraulic correction mechanism to perform adaptive correction adjustments on various steel belt conveying positions. The front end of the roller bracket 1 is symmetrically inclined and is provided with a centering positioning frame 2 for positioning the output steel belt. The bottom and upper steel belts can pass through the centering positioning frame 2 for positioning to ensure that the position of the steel belt will not have a large deviation. The centering sensor 5 is installed on an inner side wall of the centering positioning frame 2, so that the steel belt passing through the centering positioning frame 2 can use the centering sensor 5 to detect the position of the steel belt.

[0024] Specifically, when in use, the automatic controller is adopted in the steel strip composite deviation correction control system, so that the three-axis deviation correction roller 6 can be used to convey the middle layer steel strip, pass through the S-shaped composite conveying roller 8 to the main equipment conveying unit 9 to output the composite main steel strip for winding, and the unwinding and rewinding machine A3 and the unwinding and rewinding machine B4 are automatically started by the controller to drive the unwinding and rewinding roller 10 through the set centering positioning frame 2 to convey and wrap around the S-shaped composite conveying roller 8 to fit with the middle layer steel strip for composite pressing and conveying. The steel nails on the upper or lower layer are detected by the centering sensor 5 to detect the position of the steel strip. After the centering sensor 5 detects the composite deviation of the upper or bottom steel strip, the detection deviation signal is transmitted to the controller, and the controller issues a control instruction to control the hydraulic The correction adjustment seat 11 corrects the offset position of the retracting and unwinding roller 10, so that the upper steel belt is corrected to the same position as the middle steel belt. The combination of the hydraulic correction adjustment frame 13 and the hydraulic positioning frame 14 can also be used. The controller can use the hydraulic control of the hydraulic correction adjustment frame 13 to correct the offset of the middle steel belt. A certain layer of strip steel can be used as a reference, or this layer of steel belt can also perform hydraulic centering control correction by itself. At the same time, other multiple layers of steel belts all run with the center line of this layer of steel belt as the reference. The center position of the steel belt can also be artificially offset to achieve different composite states, so that the controller in the steel belt composite correction control system can automatically control, independently judge, and independently adjust the functions, so that the steel belt is stable and efficient during the composite process.
