[0024] like Figure 1 As shown, an embodiment of the utility model discloses a post-rolling energy-saving temperature control device for hot-rolled plates, comprising a workbench 1, a first limit plate 2, a second limit plate 3, a drive motor 4, a first switch 51 and a first nozzle 61, wherein the first limit plate 2 is arranged on the workbench 1, the second limit plate 3 is slidably arranged on the workbench 1, and forms a limit area with the first limit plate 2, the drive motor 4 is arranged on the workbench 1, and is drivingly connected to the second limit plate 3, the first nozzle 61 has a fixed end and a spraying end, the fixed end of the first nozzle 61 is arranged on the workbench 1, the spraying end of the first nozzle 61 spans the first limit plate 2 and is located above the limit area, the first switch 51 is arranged on the workbench 1, and is used to control the operation of the first nozzle 61, and the outer wall of the second limit plate 3 is provided with a switch bracket 31, and when the second limit plate 3 slides to the first position, the switch bracket 31 presses the first switch 51.

[0025] The user can control the driving motor 4 to drive the second limit plate 3 to slide on the workbench 1. When the second limit plate 3 slides to the first position, the switch bracket 31 presses the first switch 51, and the first nozzle 61 sprays water to the limit area, thereby realizing different limit areas using different nozzles for spraying water, solving the problem of using only one nozzle for cooling in the prior art, which would waste water.

[0026] In this embodiment, the post-rolling energy-saving temperature control device for hot-rolled plates includes a second nozzle 62 and a second switch 52, wherein the second nozzle 62 has a fixed end and a spraying end, the fixed end of the second nozzle 62 is arranged on the workbench 1, the spraying end of the second nozzle 62 spans the first limit plate 2 and is located above the limit area, the second switch 52 is arranged on the workbench 1, and is used to control the operation of the second nozzle 62, when the second limit plate 3 slides to the second position, the switch bracket 31 presses the second switch 52, and the water spraying amount of the second nozzle 62 is different from the water spraying amount of the first nozzle 61. The user can control the operation of the drive motor 4, and the drive motor 4 drives the second limit plate 3 to slide on the workbench 1, when the second limit plate 3 slides to the second position, the switch bracket 31 presses the second switch 52, and the second nozzle 62 sprays water to the limit area.

[0027] In this embodiment, when the second limiting plate 3 slides to the first position, the limiting area formed by the second limiting plate 3 and the first limiting plate 2 is the first limiting area, and when the second limiting plate 3 slides to the second position, the limiting area formed by the second limiting plate 3 and the first limiting plate 2 is the second limiting area, the second limiting area is larger than the first limiting area, and the water spraying amount of the second nozzle 62 is larger than the water spraying amount of the first nozzle 61. The larger the width of the plate, the larger the required water spraying amount, so the better the cooling effect.

[0028] In this embodiment, the post-rolling energy-saving temperature control device for hot-rolled plates includes a third nozzle 63 and a third switch 53. The third nozzle 63 has a fixed end and a spraying end. The fixed end of the third nozzle 63 is arranged on the workbench 1. The spraying end of the third nozzle 63 spans the first limit plate 2 and is located above the limit area. The third switch 53 is arranged on the workbench 1 to control the operation of the third nozzle 63. When the second limit plate 3 slides to the third position, the switch bracket 31 presses the third switch 53. The water spraying amount of the third nozzle 63 is different from that of the first nozzle 61 and the first nozzle 61. The user can control the operation of the drive motor 4, and the drive motor 4 drives the second limit plate 3 to slide on the workbench 1. When the second limit plate 3 slides to the third position, the switch bracket 31 presses the third switch 53, and the third nozzle 63 sprays water to the limit area.

[0029] In this embodiment, when the second limiting plate 3 slides to the third position, the limiting area formed by the second limiting plate 3 and the first limiting plate 2 is the third limiting area, the third limiting area is larger than the second limiting area, and the water spraying amount of the third nozzle 63 is larger than the water spraying amount of the second nozzle 62. The larger the width of the plate, the larger the required water spraying amount, so the better the cooling effect.

[0030] Specifically, the first nozzle 61 , the second nozzle 62 , and the third nozzle 63 are arranged in a vertical row.

[0031] Specifically, the first switch 51 , the second switch 52 , and the third switch 53 are arranged in a horizontal row.

[0032] Specifically, the switch bracket 31 is L-shaped.

[0033] Specifically, the length of the spraying end of the first nozzle 61 is smaller than the length of the spraying end of the second nozzle 62, and the length of the spraying end of the second nozzle 62 is smaller than the length of the spraying end of the third nozzle 63. Since the width of the third limiting area is larger than the width of the second limiting area, and the width of the second limiting area is larger than the width of the first limiting area, in order to better spray on the plate, the spraying end of the third nozzle 63 is set to be the longest.

[0034] Specifically, the switch bracket 31 has a pressing end, and the gap between two adjacent switches of the first switch 51, the second switch 52, and the third switch 53 is larger than the width of the pressing end of the switch bracket 31. This prevents the switch bracket 31 from pressing two switches at the same time.

[0035] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
