[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] The present invention provides a strip steel clamping device 100, which is mainly used to solve the problem of low strip steel surface inspection efficiency.

[0052] Please refer to Figures 1 to 6 In an embodiment of the present invention, a strip clamping device 100 is provided, comprising: a rotating frame 1, wherein the rotating frame 1 comprises a fixed frame 11 and a rotating seat 12, wherein the rotating seat 12 is rotatably arranged on the fixed frame 11; a clamping structure 2 arranged on the rotating seat 12, wherein the clamping structure 2 comprises a first clamping member 21 and a second clamping member 22, wherein the first clamping member 21 and the second clamping member 22 are arranged at intervals to form a strip clamping gap; and a clamping locking structure 3, wherein the clamping locking structure 3 comprises a fixing member 31 arranged on the first clamping member 21, and an elastic member 32 connecting the first clamping member 21 and the rotating seat 12, wherein the elastic member 32 can drive the first clamping member 21 to rotate so that the fixing member 31 abuts against the second clamping member 22 for fixing the strip.

[0053] On the whole, the rotating seat 12 of the present invention is rotatably mounted on the fixed frame 11, and the rotation angle of the rotating seat 12 can be adjusted conveniently and quickly. When in use, the fixing member 31 is disengaged from the second clamping member 22 by rotating the first clamping member 21 to overcome the elastic force of the elastic member 32, thereby opening the strip clamping gap between the first clamping member 21 and the second clamping member 22 to facilitate the insertion of the strip. The strip clamping gap can be made to be in the same plane as the strip by controlling the rotation angle of the rotating seat 12, thereby facilitating the insertion of the strip into the strip clamping gap. When the strip is inserted into the strip clamping gap and adjusted into place, the first clamping member 21 is released, and the elastic force of the elastic member 32 is used to make the fixing member 31 abut against the second clamping member 22 again, thereby maintaining the clamping fixation of the strip through the cooperation of the elastic member 32 and the fixing member 31, thereby preventing the strip from moving during the flipping operation. When the surface of the steel strip needs to be inspected, the rotating seat 12 can drive the steel strip to rotate synchronously to realize the turning operation, so that the surfaces of both sides of the steel strip can be inspected quickly.

[0054] In the embodiments of the present invention, Figures 1 to 4 The strip steel clamping device 100 also includes an unlocking structure 4, which includes a telescopic device 41 arranged on the fixed frame 11, and an adjusting member 42 arranged on the first clamping member 21. The telescopic device 41 can push the adjusting member 42 to drive the first clamping member 21 to rotate, so that the fixing member 31 rotates out of the second clamping member 22 to release the strip steel.

[0055] Among them, the adjusting member 42 and the fixing member 31 can be arranged on the first clamping member 21 at intervals along the rotation direction of the first clamping member 21. During use, the strip steel is generally inserted into the strip steel clamping gap in a horizontal state. At this time, it is necessary to rotate the first clamping member 21 to make the fixing member 31 rotate and disengage from the second clamping member 22, thereby opening the strip steel clamping gap for the strip steel to pass through. Specifically, the telescopic device 41 can be arranged on the side of the first clamping member 21. When the strip steel clamping gap is horizontal by adjusting the angle of the rotating seat 12, the telescopic device 41 and the adjusting member 42 are in the same plane. At this time, the telescopic device 41 can be used to push the adjusting member 42, thereby driving the first clamping member 21 to rotate so that the fixing member 31 rotates and disengages from the second clamping member 22, thereby opening the strip steel clamping gap for the strip steel to pass through.

[0056] Specifically, the telescopic device 41 can be a gas cylinder or an oil cylinder. By setting the telescopic device 41 on the fixed frame 11, it is possible to avoid the problem of the pipeline on the gas cylinder or the oil cylinder rotating and being entangled or knotted. Of course, the designer can also set the telescopic device 41 to other structures, which is not limited here.

[0057] In an embodiment of the present invention, a supporting member 222 is provided on the second clamping member 22, and the supporting member 222 is used to support the strip steel. The elastic member 32 can drive the first clamping member 21 to rotate, so that the fixing member 31 abuts against the supporting member 222 to fix the strip steel.

[0058] By arranging the supporting member 222 on the second clamping member 22 to cooperate with the fixing member 31, the strip steel can be clamped better. In order to prevent the supporting member 222 and the fixing member 31 from damaging the surface of the strip steel during the clamping process, thereby affecting the inspection result of the strip steel, the fixing member 31 and the supporting member 222 can be made of materials with certain protective properties, such as hardwood. Of course, the designer can also use materials such as rubber or plastic to replace hardwood, which is not limited here.

[0059] In the embodiment of the present invention, the elastic member 32 includes a torsion spring 321 , one end of the torsion spring 321 is connected to the rotating seat 12 , and the other end of the torsion spring 321 is connected to the first clamping member 21 .

[0060] By arranging a torsion spring 321 between the rotating seat 12 and the first clamping member 21, the torsion spring 321 can provide a torsion force to rotate the first clamping member 21, thereby driving the fixing member 31 on the first clamping member 21 to rotate against the supporting member 222 or the second clamping member 22, thereby clamping and fixing the strip steel. Under the elastic action of the torsion spring 321, the first clamping member 21 can automatically rotate, thereby pressing the fixing member 31 against the supporting member 222 or the second clamping member 22, for fixing the strip steel.

[0061] The present invention uses a torsion spring 321. In the absence of external force, the fixing member 31 can always maintain the clamping effect on the strip, thereby preventing the strip from moving in the strip clamping gap and improving the clamping stability of the strip. Of course, designers can also use other elastic forces to replace the torsion spring 321, such as a rubber block, which is not limited here.

[0062] In an embodiment of the present invention, the first clamping member 21 includes a first clamping roller 211 rotatably disposed on the rotating seat 12, and the second clamping member 22 includes a second clamping roller 221 fixedly disposed on the rotating seat 12, and the first clamping roller 211 and the second clamping roller 221 are spaced apart to form the strip clamping gap.

[0063] Specifically, the first clamping roller 211 and the second clamping roller 221 can be arranged in parallel, and the first clamping roller 211 and the second clamping roller 221 are arranged at intervals to form a strip clamping gap for the strip to pass through. The first clamping roller 211 is rotatably mounted on the rotating seat 12, and the second clamping roller 221 is fixedly arranged on the rotating seat 12. By rotatably arranging the first clamping roller 211, the first clamping roller 211 can be used to drive the fixing member 31 to clamp the strip. And by fixing the second clamping roller 221, it is possible to prevent the second clamping roller 221 from rolling and causing the strip to move in the strip clamping gap.

[0064] Furthermore, in order to improve the reliability of the torsion spring 321 during use, a core shaft 212 is provided at both ends of the first clamping roller 211, and two torsion springs 321 are provided, and the two torsion springs 321 are respectively sleeved on the core shaft 212. By sleeved the torsion spring 321 on the core shaft 212, the core shaft 212 can be used to limit the torsion spring 321, so that the torsion spring 321 can move along the circumferential direction of the core shaft 212, thereby better driving the first clamping roller 211 to rotate.

[0065] In the embodiments of the present invention, Figure 5 and Figure 6 A rotating structure 5 is provided between the fixed frame 11 and the rotating seat 12. The rotating structure 5 includes a plurality of rotating brackets 51 arranged on the fixed frame 11. The plurality of rotating brackets 51 are arranged at intervals around the rotating seat 12. The rotating seat 12 is rotatably provided on the fixed frame 11 through the rotating brackets 51.

[0066] Furthermore, the rotating bracket 51 includes a support 511 and a rotating wheel 512 rotatably disposed on the support 511 , and the rotating wheel 512 is overlapped with the rotating base 12 .

[0067] By setting a plurality of rotating brackets 51, the rotating seat 12 can be limited and supported. For example, four rotating brackets 51 can be set, two of which are used to support the bottom of the rotating seat 12, and the other two rotating brackets 51 are used to support the top of the rotating seat 12, so that the rotating seat 12 is limited and supported by the plurality of rotating brackets 51. Of course, the designer can also adjust the number of rotating brackets 51 as needed, and here four are taken as an example, and other numbers are not limited.

[0068] In an embodiment of the present invention, the strip clamping device 100 further includes a driving device 6, the driving device 6 has a first output shaft 61, a transmission structure 7 is provided between the first output shaft 61 and the rotating seat 12, the transmission structure 7 includes a driven member 71 provided on the rotating seat 12, and an active member 72 provided on the first output shaft 61, the driven member 71 is transmissionably connected to the active member 72. By providing the driving device 6, the rotation angle of the rotating seat 12 can be adjusted, thereby quickly realizing the flipping operation of the strip.

[0069] Specifically, the driven member 71 includes a transmission chain 711, which is connected end to end and arranged in a ring shape on the rotating seat 12; the active member 72 includes a sprocket 721, which is coaxially arranged on the first output shaft 61, and the sprocket 721 is meshed with the transmission chain 711 for transmission.

[0070] Since the chain has no elasticity, elastic sliding can be eliminated, thereby accurately ensuring the transmission ratio between the rotating seat 12 and the driving device 6, and facilitating the control of the rotation angle of the rotating seat 12. Of course, designers can also use a gear structure instead of a chain structure, which is not limited here.

[0071] The strip steel clamping device 100 of the present invention cooperates with the rotating seat 12 through the fixed frame 11, and can freely adjust the rotation angle of the rotating seat 12, so that by controlling the angle of the rotating seat 12, on the one hand, it is convenient for the strip steel to penetrate into the clamping structure 2, and on the other hand, when it is necessary to inspect the surface of the strip steel, the rotating seat 12 can drive the strip steel to rotate synchronously to realize the flipping operation. Among them, the present invention uses the first clamping member 21 and the second clamping member 22 to form a strip steel clamping gap. When the strip steel enters the strip steel clamping gap, the clamping locking structure 3 is used to fix the strip steel, so that the strip steel can rotate with the rotating seat 12, and then the strip steel can be quickly and conveniently flipped, thereby improving the inspection efficiency of the strip steel.

[0072] Please refer to Figures 7 to 10 In an embodiment of the present invention, a strip steel inspection system 200 is provided, comprising: two strip steel clamping devices 100 as described above, the two strip steel clamping devices 100 are arranged at intervals for clamping the strip steel. The specific structure, working principle and beneficial effects of the strip steel clamping device 100 are the same as those in the above-mentioned solution, and will not be described in detail here.

[0073] For details, please refer to Figures 7 to 9The two strip steel clamping devices 100 can be symmetrically arranged in the horizontal direction, and then by adjusting the rotation angle of the rotating seat 12, the strip steel clamping gaps on the two strip steel clamping devices 100 can be arranged in the same plane to facilitate the insertion of the strip steel. By arranging the two aforementioned strip steel clamping devices 100, both ends of the strip steel can be clamped at the same time, and then the strip steel can be quickly turned over by using the synchronous rotation of the two strip steel clamping devices 100.

[0074] Since the steel strip has a large weight, when the steel strip is threaded between the two steel strip clamping devices 100, the steel strip may be deformed under its own weight, causing the front end of the steel strip to bend downward and unable to pass into the other steel strip clamping gap.

[0075] In order to prevent the strip from being deformed during the strip threading process, in the embodiment of the present invention, the strip inspection system 200 further includes a strip threading guide structure 8 disposed between the two strip clamping devices 100, and the strip threading guide structure 8 includes a strip threading guide plate 81, and the strip threading guide plate 81 is movably disposed between the two strip clamping devices 100. The strip threading guide plate 81 can support the strip and prevent the strip from being deformed under the action of its own weight.

[0076] Furthermore, in order to prevent the belt threading guide structure 8 from affecting the strip turning operation, in an embodiment of the present invention, the belt threading guide structure 8 also includes at least one lifting device 82, and the lifting device 82 is connected to the belt threading guide plate 81, and is used to adjust the height position of the belt threading guide plate 81.

[0077] Specifically, two lifting devices may be provided, and the two lifting devices are respectively connected to the two ends of the strip threading guide plate 81. When the strip needs to be threaded, the lifting device 82 is used to lift the strip threading guide plate 81, so that the strip can be passed along the strip threading guide plate 81 into the two strip inspection gaps and clamped. Then, the lifting device 82 is used to lower the height of the strip threading guide plate 81, leaving an operating space for turning over the strip.

[0078] In order to avoid the problem of twisting of the strip steel due to the asynchronism of the strip steel clamping device 100 during the flipping process. Fig.10 A driving device 6 is provided between the two strip clamping devices 100 , and the driving device 6 also includes a second output shaft 62 . The first output shaft 61 and the second output shaft 62 are respectively connected to the corresponding rotating seat 12 through a transmission structure 7 .

[0079] The first output shaft 61 and the second output shaft 62 can be coaxially arranged for synchronous rotation. The driving device 6 can be composed of a driving motor 63 and a synchronous reducer 64 connected to the driving motor 63. The first output shaft 61 and the second output shaft 62 are arranged on the synchronous reducer 64. The first output shaft 61 and the second output shaft 62 are respectively connected to the corresponding rotating seat 12 through the transmission structure 7, so as to drive the two rotating seats 12 to rotate synchronously.

[0080] The two strip steel clamping devices 100 share a driving device 6, and the driving device 6 can synchronously drive the two rotating seats 12 to rotate, thereby eliminating the problem of asynchronous rotation between the two rotating seats 12 and avoiding the problem of strip steel being twisted during the strip steel turning process. Of course, designers can also use other synchronous drive structures, which are not limited here.
