[0023] The utility model provides a technical solution: Figure 1 - Figure 5As shown, in this embodiment, a correction device for galvanized steel plate processing includes a tunnel box 1, two support frames 8 are fixedly connected to the inner bottom of the tunnel box 1, one side of the two support frames 8 is rotatably connected to a rotating rod 13, the outer side walls of the two rotating rods 13 are fixedly connected to multiple driving gears 16, one side of the multiple driving gears 16 is meshed with an adjusting rack 17, one end of the multiple adjusting racks 17 is fixedly connected to a sliding block 12, the outer side walls of the multiple sliding blocks 12 are slidably connected to the inner wall of the support frame 8, one side of the multiple sliding blocks 12 is rotatably connected to a clamping roller 11, both sides of the tunnel box 1 are fixedly connected to L-shaped mounting frames 7, a rotating shaft 18 is rotatably connected between the two L-shaped mounting frames 7, and the rotating shaft 18 is fixedly connected to the outer side walls of the tunnel box 1. Bevel gears 2 15 are fixedly connected to both sides of the outer wall of the moving shaft 18, and one side of the two bevel gears 2 15 is meshed with bevel gears 14. One side of the two bevel gears 14 is fixedly connected to one end of the two rotating rods 13 respectively. By pulling the hexagonal connecting rod 21, one side of the hexagonal connecting rod 21 is pulled out from the hexagonal limiting ring 19, and then the hexagonal connecting rod 21 is rotated to rotate the two rotating rods 13. The driving gear 16 on the rotating rod 13 drives the adjusting racks 17 on the two supporting frames 8 to move, and the clamping rollers 2 11 in the tunnel box 1 are moved at the same time. The rotating shaft 18 cooperates with the rotating rod 13 to quickly adjust the distance between the clamping roller 2 11 and the clamping roller 10, thereby improving the correction efficiency of the galvanized steel plate.

[0024] like Figure 2 - Figure 4 As shown, a hexagonal limit ring 19 is fixedly connected to one side of the L-shaped mounting frame 7, a hexagonal connecting rod 21 is fixedly connected to one end of the rotating shaft 18, and a hexagonal sliding ring 20 is slidably connected to the outer wall of the hexagonal connecting rod 21. One side of the outer wall of the hexagonal sliding ring 20 is clamped with the inner wall of the hexagonal limit ring 19. Through the cooperation of the hexagonal connecting rod 21, the hexagonal sliding ring 20 and the hexagonal limit ring 19, it can be prevented that the staff accidentally touches the hexagonal connecting rod 21 when the equipment is running, resulting in the calibrated galvanized steel plate being unqualified.

[0025] like Figure 2 As shown, a driving device 3 is fixedly installed on one side of the tunnel box 1, and a transmission device 9 is fixedly installed on the other side of the support frame 8. The input end of the transmission device 9 is transmission-connected to the output end of the driving device 3. A plurality of clamping rollers 10 are rotatably connected between the two support frames 8. The input ends of the plurality of clamping rollers 10 are transmission-connected to the output end of the transmission device 9. By turning on the driving device 3, the clamping roller 10 cooperates with the clamping roller 2 11 to straighten and correct the galvanized steel sheet.

[0026] like Figure 1 and Figure 2 As shown, a feeding mechanism 2 is fixedly installed at the lower middle part of one side of the tunnel box 1, and the feeding mechanism 2 is used to facilitate the feeding of galvanized steel sheets into the tunnel box 1 for processing.

[0027] like Figure 1 , Figure 2 and Figure 5 As shown, a mounting platform 4 is fixedly connected to one side of the lower end of the feeding mechanism 2, and guide frames 5 are fixedly connected to both sides of the upper end of the feeding mechanism 2. The inner walls of the two guide frames 5 are slidably connected to U-shaped clamping plates 6. The galvanized steel plates on the feeding mechanism 2 can be proofread through the two U-shaped clamping plates 6 to prevent the galvanized steel plates from deviating from the center of the correction device, which may cause the device to fail to apply uniform correction force to both sides of the steel plates, thereby improving the calibration quality of the device.

[0028] like Figure 5 As shown, a cylinder 22 is fixedly installed on one side of the lower end of the mounting table 4, and the output end of the cylinder 22 is rotatably connected to two pulling rods 23, and one end of the two pulling rods 23 is rotatably connected to one end of two U-shaped clamping plates 6 respectively. By turning on the cylinder 22, the two pulling rods 23 pull the two U-shaped clamping plates 6, so that the two U-shaped clamping plates 6 can calibrate the galvanized steel plates on the feeding mechanism 2.

[0029] like Figure 5 As shown, a guide rail 24 is fixedly connected to the other side of the lower end of the mounting platform 4 , and the outer side wall of the guide rail 24 is slidably connected to one side of the U-shaped clamping plate 6 , and the guide rail 24 is used to limit the sliding direction of the two U-shaped clamping plates 6 .

[0030] The utility model provides a correction device for galvanized steel plate processing, and the specific working principle is as follows:

[0031] When calibrating the produced galvanized steel sheet, first place the galvanized steel sheet on the feeding mechanism 2. When the galvanized steel sheet passes through the guide frame 5, the two pulling rods 23 are pulled by the cylinder 22 to move, so that the two U-shaped clamping plates 6 slide on the guide rails 24 under the pulling force of the pulling rods 23. In the process of the movement of the two pulling rods 23, the galvanized steel sheet is calibrated. When the galvanized steel sheet enters the tunnel box 1, the driving device 3 is turned on, and the compression roller 10 and the compression roller 2 11 cooperate to calibrate the galvanized steel sheet. When the galvanized steel sheet with different thicknesses is calibrated, the galvanized steel sheet is calibrated. When calibrating a galvanized steel plate of different thicknesses, pull the hexagonal connecting rod 21, pull one side of the hexagonal connecting rod 21 out of the hexagonal limiting ring 19, and rotate the hexagonal connecting rod 21 to rotate the two rotating rods 13. The driving gear 16 on the rotating rod 13 drives the adjusting racks 17 on the two supporting frames 8 to move, and the clamping roller 2 11 in the tunnel box 1 is moved at the same time, so as to adjust the distance between the clamping roller 10 and the clamping roller 2 11 to be the same as the thickness of the steel plate, and then fix the rotating shaft 18, and repeat the above operation to calibrate the galvanized steel plates of different thicknesses.
