[0032] In order to better understand the technical solutions provided by the embodiments of the present specification, the technical solutions of the embodiments of the present specification will be described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present specification and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present specification, and are not limitations of the technical solutions of the present specification. In the case of no conflict, the technical features in the embodiments of the present specification and the embodiments can be combined with each other.

[0033] In this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises... " does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the recited element. The term "two or more" includes two or more than two.

[0034] At present, in the cold rolling process of the metallurgical industry, when the three-roll coating machine performs pre-spraying strip position adjustment operation, the width of the running strip changes each time. In order to avoid the coating liquid overflowing to the surface of the strip, the operator needs to perform strip position adjustment operation. Because the strip position is at the edge of the running strip and is relatively high, there is no reliable standing point and safety belt hanging point around, which leads to a very high safety risk of this operation. In addition, when the coating machine moves horizontally into the line, the top of the coating machine is only 1.5mm away from the running strip, and the conventional adjustment strip method cannot be installed in the coating machine position, so that safety problems are easily generated during the strip coating process.

[0035] The strip coating machine and the strip annealing device provided by the embodiments of the present application can improve the safety of the strip coating operation.

[0036] Figure 1 A schematic partial structure diagram of a strip coating machine provided by the embodiments of the present application is shown in FIG. 1. In some examples, referring to FIG. 1, Figure 1The application provides a strip steel coating machine, which comprises a coating member 100, a strip 200, a driving device 300 and a control device. The coating member 100 is provided with a coating groove 110, the strip 200 is arranged in the coating groove 110, the length direction of the strip 200 is arranged along the length direction of the coating groove 110, the length of the strip 200 is smaller than the length of the coating groove 110, and the strip 200 can move back and forth in the coating groove 110 along a first direction X, so that the pre-coating liquid in the coating groove 110 is applied on the strip steel. The driving device 300 is connected with the strip 200, and the driving device 300 can drive the strip 200 to move back and forth. The control device is in communication connection with the driving device 300, so as to control the start and stop of the driving device 300.

[0037] For example, referring to Figure 1 In the conveying path of the strip steel, the length direction of the coating groove 110 can intersect with the conveying direction of the strip steel, the pre-coating liquid is arranged in the coating groove 110, and the strip 200 is arranged in the coating groove 110. The pre-coating liquid can be applied to the pre-coating position of the strip steel by controlling the position or height of the strip 200.

[0038] In some examples, referring to Figure 1 The length direction of the coating groove 110 can be perpendicular to the conveying direction of the strip steel, and the first direction X can be the length direction of the coating groove 110.

[0039] In some examples, the first direction can intersect with the length direction of the coating groove, for example, the first direction has an included angle with the length direction of the coating groove, and the included angle can be less than 10°. For another example, the width of the strip can be smaller than the width of the coating groove, so that the strip has a certain moving or rotating space in the width direction of the coating groove.

[0040] In some examples, the control device comprises a control cabinet and a remote control end, the remote control end can be in communication connection with the control cabinet, and the control cabinet can be electrically connected with the driving device, so as to control the start and stop of the driving device.

[0041] For example, the control device can avoid the personnel from contacting or approaching the running strip steel, the remote control end and the control cabinet can receive the signals related to the strip steel coating, and the moving direction or rotating direction of the strip is adjusted based on the signals, so as to change the position or inclination angle of the strip, and the coating operation of the strip steel is completed after the strip steel passes through the strip.

[0042] Figure 2 A schematic partial structure diagram of a strip steel coating machine provided by the embodiment of the application is shown. In some examples, referring to Figure 2The driving device comprises a driving motor 310 and a connecting wire 320, the driving motor 310 is connected with the drawbar 200 through the connecting wire 320, and the driving motor 310 can be used to drive the connecting wire 320 to move or rotate, so as to drive the drawbar 200 to reciprocate in the first direction X in the coating groove 110.

[0043] For example, during the operation of the driving motor, the driving motor can drive the drawbar through the connecting wire. By setting the program of the driving motor, the position or other parameters of the drawbar can be controlled by regulating the driving motor.

[0044] In some examples, referring to Figure 2 The driving motor 310 is connected with the connecting wire 320, and the driving motor 310 can rotate to drive the drawbar 200 to move in the first direction X.

[0045] For example, the driving motor can have a rotating shaft, and the connecting wire can be fixed to the rotating shaft or sleeved on the rotating shaft. By controlling the driving motor, the movement distance of the connecting wire can be controlled, and the movement distance of the drawbar is further controlled through the connecting wire, so as to adjust the coating position of the strip steel.

[0046] In some examples, referring to Figure 2 The number of the driving motors 310 is at least two, and the at least two driving motors 310 are arranged on opposite sides of the drawbar 200 in the first direction X.

[0047] For example, the driving motor can drive the connecting wire to operate in a rotating manner, and the rotating directions of the oppositely arranged driving motors can be oppositely arranged to realize the transmission of the drawbar.

[0048] In some examples, referring to Figure 2 The connecting wire 320 can be arranged in a head-to-tail manner, the connecting wire 320 can penetrate the drawbar 200, and the connecting wire 200 is sleeved on the driving motor 310. In addition, after the connecting wire 320 is sleeved on the driving motor 310, two sides parallel to each other can be formed, and one side of the connecting wire 320 can be fixedly connected with the drawbar 200, so as to avoid the phenomenon that the connecting wire 320 cannot drive the drawbar 200 to move.

[0049] For example, the connecting wire is sleeved on the driving motor, and the connecting wire can penetrate the drawbar, and the drawbar can be kept on the connecting wire. The driving motor serves as a driving part, and the connecting wire serves as a driven part, so as to realize the transmission of the drawbar.

[0050] In some examples, referring to Figure 2 Part of the connecting wire 320 is located between the drawbar 200 and the groove bottom of the coating groove 110.

[0051] For example, the connection line can cover part of the connecting line to avoid the connecting line from being broken by contacting the material in the coating tank.

[0052] In some examples, the connection line can be made of a material resistant to corrosion to avoid being corroded by the pre-coating liquid.

[0053] In some examples, the connection line can have a certain toughness to avoid being damaged or broken by the force of the driving motor.

[0054] In some examples, the connection line is an ultra-high molecular weight polyethylene line, which has a molecular weight of usually more than 1 million to 1.5 million, has good wear resistance, impact resistance, and chemical corrosion resistance, and can be better applied to the processing environment of the strip steel.

[0055] In some examples, referring to Figure 2 , the connection line 320 can be sleeved on the rotating shaft of the two driving motors 310, and the driving motor 310 drives the connection line 320 to rotate, and the connection line 320 further drives the suction strip 200 to move synchronously.

[0056] For example, by controlling the rotation angle of the driving motor, the moving distance of the suction strip can be controlled.

[0057] In some examples, the number of connection lines is at least two, the connection lines are sleeved on the driving motor, and the two ends of the connection lines are fixed to the same side of the suction strip in the first direction.

[0058] For example, the rotation of one of the driving motors can make the connection line sleeved on the driving motor continue to wind the driving motor, that is, shorten the distance between the driving motor and the suction strip, so that the suction strip moves towards the driving motor. At the same time, the number of winding turns of the connection line on the other driving motor is reduced to avoid the force of the two connection lines being opposite to each other and causing the connection line to break.

[0059] It should be noted that although the drawings of the two connection lines are not shown, the corresponding embodiments of the two connection lines can be reproduced through the above description.

[0060] In some examples, the driving motor is a bidirectional motor, for example, the motor can be forward rotated and reverse rotated.

[0061] The driving motor can be a 24V direct current bidirectional motor to be suitable for the strip steel processing environment.

[0062] In some examples, the driving motor can be controlled by a remote control device, for example, a remote controller, and the remote control device, for example, controls the driving motor according to a predetermined design to further control the movement of the suction strip in the first direction.

[0063] In some examples, the two driving motors can be set to rotate in the same direction or in opposite directions based on the difference between the positions of the two driving motors. For example, when the connecting line is arranged around the driving motor, the rotation shaft of the driving motor is perpendicular to the first direction, and the two driving motors are located on the same side of the connecting line, the two driving motors can be set to rotate in the same direction or in opposite directions. For another example, when the two driving motors are located on opposite sides of the connecting line, one driving motor is set to rotate in the same direction, and the other driving motor is set to rotate in the opposite direction.

[0064] In some examples, one side of the strip in the first direction can be fixedly connected to the connecting line, for example, by bonding or binding. In the case where the connecting line penetrates the strip, the strip on the side where the connecting line is fixedly connected can avoid the connecting line on the other side from contacting the strip and affecting the movement of the strip, and can avoid the situation where the movement distance of the strip does not match the set distance.

[0065] In some examples, in the case where two driving motors are provided, the connecting line can be provided in two groups, and the two groups of connecting lines are connected to opposite sides of the strip and the two driving motors, respectively. The connecting line can be fixed to the rotation shaft of the driving motor, and the driving motor can drive the movement of the strip through the connecting line during rotation. For example, one group of connecting lines can be wound around the driving motor during actuation of the driving motor, and the other group of connecting lines can be separated from the driving motor.

[0066] In some examples, the connecting line can be provided in one or more, for example, a plurality of connecting lines are woven or made into a whole connecting line through other processes to improve the toughness of the connecting line.

[0067] In some examples, the driving device includes a hydraulic rod, the hydraulic rod is connected to the connecting line, and the hydraulic rod can drive the strip to move in the first direction.

[0068] For example, the hydraulic rod can drive the strip to move in the first direction through hydraulic means. The hydraulic direction of the hydraulic rod can be the first direction, and the hydraulic rod can be arranged on both opposite sides of the strip in the first direction, so that the hydraulic rod can drive the strip to move in the first direction during extension and contraction in the first direction.

[0069] In some examples, the remote control device can be communicatively connected to the hydraulic rod, and the actuation end of the hydraulic rod can be connected to the driving motor. By pressing the corresponding button in the remote control device, the distance between the two driving motors can be controlled, and thus the tension or relaxation state of the connecting line can be controlled.

[0070] It should be noted that although the hydraulic rod is not shown in the drawings for driving the strip, the corresponding embodiments can be reproduced through the above description.

[0071] Figure 3 A schematic partial structure diagram of a control device of a strip coating machine is provided for embodiments of the present application. In some examples, referenceFigure 3 The control device 400 can be used to control the strip drawing, for example, to control the one-way movement of the strip drawing, and to control the zooming of the connecting line.

[0072] In some examples, the driving device can further comprise a position adjusting device. The position adjusting device is connected to the driving motor, and the position adjusting device can adjust the position of the driving motor to tighten or loosen the connecting line.

[0073] For example, a guide rail can be added to the rack to control the position of the driving motor.

[0074] In some examples, a tension detection device can be provided to detect the tension of the connecting line, and the tensioning or loosening state of the connecting line can be determined based on the detection result.

[0075] In some examples, the present application further provides a strip annealing device, which comprises the strip coating machine according to any one of the technical solutions described above.

[0076] It should be noted that in the above examples, the description of each example has its own emphasis, and the parts not described in detail in a certain example can be referred to the relevant description of other examples.
