[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] The embodiment of the present application provides a correction device for a strip steel production line and a strip steel production line, which can solve the problem in the prior art that when the automatic strip steel correction device is used on the production line, the production line needs to be significantly modified so that the automatic strip steel correction device can be set in the production line, and the structure is complex, a large installation space is required, and it is difficult to install on an old production line.

[0030] The original production line includes a leveling module 8 , a milling module 6 , a delivery module 10 and a pre-bending module 7 which are arranged in sequence along the forward direction of the steel strip 4 , wherein the milling module 6 includes a rough milling machine 61 and a fine milling machine 62 .

[0031] like Figure 1 and Figure 3 As shown, on the one hand, the present application provides a deviation correction device for a strip steel production line, which comprises:

[0032] Three adjusting mechanisms 2 are arranged at intervals along the forward direction of the steel strip 4, two of which are respectively arranged at the inlet and outlet sides of the milling module 6, and the other adjusting mechanism 2 is arranged at the outlet side of the pre-bending module 7. The adjusting mechanism 2 is arranged outside the vertical projection range of the steel strip 4, and is used to adjust the position of the steel strip 4 along the first direction according to the size and position parameters of the steel strip 4.

[0033] When the deviation correction device for the strip steel production line is used, three adjustment mechanisms 2 are arranged at intervals along the advancing direction of the strip steel 4, wherein two adjustment mechanisms 2 are arranged at the inlet side and the outlet side of the milling module 6, respectively, and another adjustment mechanism 2 is arranged at the outlet side of the pre-bending module 7. The adjustment mechanism 2 is used to be arranged outside the vertical projection range of the strip steel 4, and is used to adjust the position of the strip steel 4 along the first direction according to the size and position parameters of the strip steel 4. Since the strip steel 4 is adjusted at the inlet side and the outlet side of the milling module 6 and the outlet side of the pre-bending module 7, the quality of the strip steel 4 can be improved, and the adjustment mechanism 2 is arranged outside the vertical projection range of the strip steel 4, the adjustment mechanism 2 can be arranged outside the old production line, and can be installed without affecting the original production line, the structure is simple, and the installation is convenient, which solves the problem that when the automatic deviation correction device for the strip steel is used on the production line in the prior art, the production line needs to be greatly modified before the automatic deviation correction device for the strip steel can be arranged in the production line, and the structure is complex, a large installation space is required, and it is difficult to install on the old production line.

[0034] In this example, the first direction is perpendicular to the advancing direction of the steel strip 4. The deviation correcting device for the steel strip production line is started and closed synchronously with the production line.

[0035] like Figure 1 and Figure 3 As shown, in some optional embodiments, the adjustment mechanism 2 includes:

[0036] Two adjusting vertical rollers 21 are arranged at intervals along the first direction, and the two adjusting vertical rollers 21 are used to abut against two sides of the strip steel 4;

[0037] The driving unit 22 is used to drive the adjusting vertical roller 21 to move along the first direction to adjust the position of the steel strip 4 in the first direction.

[0038] In this embodiment, the structure of the adjustment mechanism 2 is specifically described. The adjustment mechanism 2 includes two adjustment vertical rollers 21 and a driving unit 22, wherein the two adjustment vertical rollers 21 are arranged at intervals along the first direction and abut against both sides of the strip steel 4. The driving unit 22 is used to drive the two adjustment vertical rollers 21 to move synchronously along the first direction to adjust the position of the strip steel 4 in the first direction. The structure is simple and convenient to install on an old production line.

[0039] like Figure 1 and Figure 3 As shown, in some optional embodiments, three measuring mechanisms 1 are further included. The measuring mechanisms 1 are used to be set within the vertical projection range of the steel strip 4 and to be set at intervals from the steel strip 4. The measuring mechanisms 1 correspond one-to-one to the adjusting mechanisms 2, are located on the inlet side of the adjusting mechanisms 2, and are used to measure the size and position parameters of the steel strip 4.

[0040] In this embodiment, the correction device for the strip steel production line also includes three measuring mechanisms 1. The measuring mechanisms 1 are used to be set within the vertical projection range of the strip steel 4 and are used to be set at intervals with the strip steel 4. The measuring mechanisms 1 correspond one-to-one to the adjustment mechanisms 2 and are signal-connected to the corresponding adjustment mechanisms 2. The measuring mechanisms 1 are located on the entrance side of the corresponding adjustment mechanisms 2 and are used to measure the size and position parameters of the strip steel 4 and feed back the measurement results to the corresponding adjustment mechanisms 2. The correction process is simpler and more convenient.

[0041] like Figure 2 As shown, in some optional embodiments, the measuring mechanism 1 includes:

[0042] A measuring transmitter 12, which is arranged above the steel strip 4, and is used to emit a plurality of lasers arranged at intervals along a first direction, with adjacent lasers spaced at a set distance;

[0043] The measuring receiver 11 is arranged below the steel strip 4 and is used to receive the laser light outside the vertical projection range of the steel strip 4 .

[0044] In this embodiment, the structure of the measuring mechanism 1 is specifically described. The measuring mechanism 1 includes a measuring transmitter 12 and a measuring receiver 11, wherein the measuring transmitter 12 is used to be arranged above the steel strip 4, and the measuring transmitter 12 is used to emit multiple lasers arranged at intervals along a first direction, and adjacent lasers are spaced at a set distance. The measuring receiver 11 is used to be arranged below the steel strip 4, and is used to receive lasers outside the vertical projection range of the steel strip 4. The position and size of the steel strip 4 are measured by laser. The position and size of the steel strip 4 can be measured without affecting the original production line, which is convenient for installation on old production lines and prevents the steel strip 4 from deviating and colliding with the measuring mechanism 1, thereby improving safety.

[0045] like Figure 1-Figure 3 As shown, in some optional embodiments, both ends of the measuring transmitter 12 and the measuring receiver 11 of the two measuring mechanisms 1 located on the inlet side and the outlet side of the milling module 6 extend out of the vertical projection range of the steel strip 4, and one end of the measuring transmitter 12 and the measuring receiver 11 of the measuring mechanism 1 located on the outlet side of the pre-bending module 7 extends out of the vertical projection range of the steel strip 4.

[0046] In this embodiment, both ends of the measuring transmitter 12 and the measuring receiver 11 of the two measuring mechanisms 1 located on the inlet side and the outlet side of the milling module 6 extend out of the vertical projection range of the steel strip 4. In order to ensure the quality of the steel strip 4 after milling, it is necessary to accurately measure the steel strip 4 here. The measuring transmitter 12 and the measuring receiver 11 of the measuring mechanism 1 located on the outlet side of the pre-bending module 7 have one end extending out of the vertical projection range of the steel strip 4, and the other end located within the vertical projection range of the steel strip 4. After the previous two deviation corrections, only one-side measurement of the size and position of the steel strip 4 is required here, saving the cost of the measuring mechanism 1.

[0047] like Figure 1 As shown, in some optional embodiments, a plurality of dust removal units 3 are further included. The dust removal units 3 are arranged one by one corresponding to the measuring mechanism 1 and are used to clean impurities on the measuring mechanism 1.

[0048] In this embodiment, the deviation correction device for the strip steel production line also includes a plurality of dust removal units 3, which are arranged one by one with the measuring mechanism 1 and are used to clean impurities on the measuring mechanism 1. Due to the harsh on-site working environment, it is easy to be affected by dust, iron filings, iron powder and other impurities, and obstructions are easily attached to the surface of the measuring mechanism 1, especially the measuring receiver 11 installed under the strip steel 4, causing abnormal measurement results of the measuring mechanism 1 and affecting the measurement accuracy. For this reason, the dust removal unit 3 is designed near the measuring receiver 11, and dust is removed by blowing, so as to ensure that the surface of the measuring receiver 11 is clean.

[0049] In this example, the dust removal unit 3 is started at set intervals to save energy.

[0050] In some optional embodiments, an alarm mechanism is further included, which is connected to the measuring mechanism 1. When the size and position parameters of the steel strip 4 exceed the standard parameter setting range, the alarm mechanism alarms.

[0051] In this embodiment, the deviation correction device for the strip steel production line also includes an alarm mechanism, which is connected to the measuring mechanism 1. When the size and position parameters of the strip steel 4 exceed the standard parameter setting range, the alarm mechanism alarms to prevent the adjustment mechanism 2 from being unable to handle the large offset value, resulting in damage to the equipment.

[0052] In this example, when the measured deviation value of the strip 4 is within the error range, the alarm mechanism shows a green indicator light; when the deviation value exceeds the error range but is less than the fault value, the alarm mechanism shows a yellow indicator light, and the adjustment mechanism 2 will start to automatically correct the deviation until the deviation error of the strip 4 is within the allowable error range; when the deviation value is greater than the fault value, the alarm mechanism shows a red indicator light, and the alarm mechanism starts to sound and flash, reminding the operator to intervene manually to avoid untimely correction that may lead to further expansion of the fault and damage to the equipment.

[0053] like Figure 1 As shown, in some optional embodiments, it also includes a plurality of display units 9 spaced apart along the forward direction of the steel strip 4, all of the display units 9 are located on one side of the steel strip 4, and are signal-connected to all of the measuring mechanisms 1 for displaying the measurement results of the measuring mechanisms 1.

[0054] In this embodiment, the correction device for the strip steel production line also includes a plurality of display units 9 arranged at intervals along the forward direction of the strip steel 4. All display units 9 are located on one side of the strip steel 4 and are connected to the signals of all measuring mechanisms 1 for displaying the measurement results of the measuring mechanisms 1. Since the strip steel 4 production line is long, a plurality of display units 9 arranged at intervals can facilitate the staff to view the results of the measuring mechanisms 1.

[0055] In this example, a wireless connection module is provided on the display unit 9, which can transmit information to the mobile terminal. The result displayed by the display unit 9 is the average value of multiple groups of measurement data after removing the maximum value and the minimum value.

[0056] like Figure 1 As shown, in some optional embodiments, a guide mechanism 5 is further included. The guide mechanism 5 is used to be arranged on the inlet side of the leveling module 8. The guide mechanism 5 includes two guide rollers 51 arranged at intervals along the first direction. The two guide rollers 51 are used to abut against both sides of the strip 4.

[0057] In this embodiment, the deviation correction device for the strip steel production line also includes a guide mechanism 5, which is used to be arranged on the entrance side of the leveling module 8. The guide mechanism 5 includes two guide vertical rollers 51 arranged at intervals along the first direction. The two guide vertical rollers 51 are used to abut against both sides of the strip steel 4 to prevent the strip steel 4 from being excessively deviated when entering the leveling module 8.

[0058] like Figure 1 and Figure 3 As shown, on the other hand, the present application also provides a strip steel production line, which includes the above-mentioned deviation correction device for the strip steel production line.

[0059] When the deviation correction device for the strip steel production line is used, three adjustment mechanisms 2 are arranged at intervals along the advancing direction of the strip steel 4, wherein two adjustment mechanisms 2 are arranged at the inlet side and the outlet side of the milling module 6, respectively, and another adjustment mechanism 2 is arranged at the outlet side of the pre-bending module 7. The adjustment mechanism 2 is used to be arranged outside the vertical projection range of the strip steel 4, and is used to adjust the position of the strip steel 4 along the first direction according to the size and position parameters of the strip steel 4. Since the strip steel 4 is adjusted at the inlet side and the outlet side of the milling module 6 and the outlet side of the pre-bending module 7, the quality of the strip steel 4 can be improved, and the adjustment mechanism 2 is arranged outside the vertical projection range of the strip steel 4, the adjustment mechanism 2 can be arranged outside the old production line, and can be installed without affecting the original production line, the structure is simple, and the installation is convenient, which solves the problem that when the automatic deviation correction device for the strip steel is used on the production line in the prior art, the production line needs to be greatly modified before the automatic deviation correction device for the strip steel can be arranged in the production line, and the structure is complex, a large installation space is required, and it is difficult to install on the old production line.
