referring to fig. 1, a schematic structural diagram of a cleaning device for a zinc pot working roll provided by an embodiment of the application is shown.
a cleaning device for a zinc pot working roll is used for cleaning impurities accumulated on a sink roll 100 and a stabilizing roll 200, and comprises a bottom plate 10, a guide rail 20, a frame 30, a telescopic mechanism 31, a first driving element 40, a second driving element and a scraper 32; wherein the guide rail 20 is arranged on the bottom plate 10, and the frame 30 is connected with the guide rail 20; the first driving element 40 is connected to the guide rail 20, and is used for driving the guide rail 20 to move relative to the base plate 10 and driving the frame 30 to move along a first direction; the telescopic mechanism 31 is fixed on the frame 30; the second driving element is connected with the telescopic mechanism 31 and is used for driving the telescopic mechanism 31 to extend and retract in a second direction perpendicular to the first direction; the scraper 32 is arranged at one end of the telescopic mechanism 31 far away from the guide rail 20 and is used for moving to a target position to clean the working roller under the driving of the first driving element 40 and the second driving element.
In the present embodiment, the guide rail 20 includes a primary rail 21 and a secondary rail 22. The main rail 21 is in transmission connection with the first driving element 40 and is also fixedly connected with the frame 30. The main rail 21 is driven by the first driving element 40, so that the frame 30 is moved together relative to the base plate 10. Specifically, the control of the left and right movement of the carriage 30 (the control of the movement speed of the carriage 30) is realized.
in the embodiment of the present application, the driving connection of the main rail 21 and the rack 30 may be, but is not limited to, a chain driving connection or a screw driving connection. The first drive element 40 may be, but is not limited to, a variable frequency motor. For example, in another possible embodiment, the first driving element 40 may also be a stepping motor or a servo motor, and the driving connection between the main rail 21 and the frame 30 may also be a gear transmission or a worm gear transmission. Therefore, it should be understood herein that those skilled in the art can substitute the means employed in the present embodiment according to actual needs.
With continued reference to fig. 1, in view of the dust-proof problem, in a possible embodiment, in order to prevent dust from adhering to the guide rail 20 and affecting the transmission effect of the frame 30, a dust-proof cover may be further provided on the main rail 21, and a sprocket cover 41 may be provided at the sprocket where the main rail 21 is connected to the inverter motor.
further, since the main rail 21 of the present embodiment not only needs to transmit the power to the frame 30, but also has a function of fixing the frame 30, when the frame 30 receives an external force in a non-transmission direction, it is very easy to cause a damage of the connection structure between the frame 30 and the main rail 21, and therefore, the sub rail 22 parallel to the main rail 21 is further provided in the present embodiment. The frame 30 is connected to the sub-rail 22 through a sliding groove formed on a surface thereof adjacent to the bottom plate 10, so that a moving path of the frame 30 is fixed, resistance of the frame 30 to an external force is enhanced, and reliability of a connection structure between the frame 30 and the guide rail 20 is improved.
With continued reference to fig. 1, in the embodiment of the present application, the two ends of the guide rail 20 are further provided with a limiting member 23, and the left and right sides of the rack 30 are respectively provided with a touch plate 33. When the frame 30 moves to both ends of the guide rail 20 (for example, when the frame 30 moves to the leftmost end or the rightmost end of the guide rail 20), the contact plate 33 may be engaged with the stopper 23, thereby preventing the frame 30 from being separated from the rail.
Specifically, in the embodiment of the present application, the position-limiting element 23 may be a buffer element with a pure mechanical structure, such as a spring buffer element, or may be a travel switch with a signal triggering function. When the position limiting member 23 is a travel switch, the frame 30 moving to the two ends of the guide rail 20 triggers an electrical signal through the travel switch, and then the triggered electrical signal of the travel switch is fed back to the controller (in this embodiment, the controller may be integrated with the control panel), that is, the controller can control the first driving element 40 to stop driving or switch to reverse driving in time.
With continued reference to fig. 1, in the present embodiment, the scraper 32 includes a scraper arm 321 and a scraper head 322. In order to facilitate the replacement of the scraper 32, the blade head 322 is fixedly connected to one end of the blade arm 321, and the other end of the blade arm 321 is detachably connected to the end of the telescopic mechanism 31 away from the guide rail 20 in the present embodiment, because it is considered that the scraper 32 may need to be replaced during use.
Further, in the embodiment of the present application, the cutting head 322 may be made of a material having a relatively high hardness, such as 40 steel, 45 steel, etc., in consideration that the hardness of the cutting head 322 needs to be greater than the hardness of the impurities attached to the work roll to effectively remove the impurities.
further, with continued reference to fig. 1, in one embodiment of the present application, the apparatus may include a first telescoping mechanism and a second telescoping mechanism. The one end that guide rail 20 was kept away from to first telescopic machanism is connected with first scraper, and the one end that guide rail 20 was kept away from to second telescopic machanism is connected with the second scraper, and the arm of a knife of first scraper is longer than the arm of a knife of second scraper. The first scraper is used for cleaning the sink roller, and the second scraper is used for cleaning the stabilizing roller.
It should be understood that in the embodiment of the present application, the purpose of providing the first telescopic mechanism and the second telescopic mechanism on the frame 30 at the same time is to realize cleaning of the sink roller and the stabilizing roller at the same time. In practical applications, the number of the telescopic mechanisms 31 on the rack 30 can be one, two or other according to practical requirements.
Further, in this embodiment of the present application, the first telescoping mechanism and the second telescoping mechanism may be air cylinders, and the second driving element may be a pneumatic control valve station, and the pneumatic control valve station is connected to the air cylinders through a tow chain 311 to provide an air source for the air cylinders. The pneumatic control valve station can comprise a panel type pressure valve, a reversing valve, a speed regulating valve, a pressure gauge, a triple piece and the like. The air source required by the air cylinder can be generated through the pneumatic control valve station, the air cylinder is driven, and therefore the telescopic mechanism 31 is controlled to be telescopic relative to the guide rail 20, specifically, the scraper 32 is controlled to move up and down. Similarly, a cylinder cover 312 may be provided at the cylinder in order to prevent dust from entering the cylinder.
further, in the present embodiment, a pressure gauge may be used to detect the contact pressure between the tool bit 322 and the work roll. In other words, in the embodiment of the present application, the cleaning force of the scraper 32 can be adjusted according to the contact pressure detected by the pressure gauge 51, so as to prevent the scraper 32 from causing excessive frictional resistance to the working roll in the process of cleaning impurities, which affects the normal operation of the production line.

referring to fig. 2, the work rolls include a sink roll 100 and a stabilizing roll 200. Among them, the sink roll 100 is used to change the transfer direction of the strip, and the stabilizing roll 200 is used to fix the transfer direction of the strip. In the galvanizing process, the sink roll 100 and the stabilizing roll 200 are driven by the strip steel to rotate.
In the embodiment of the present application, in order to remove foreign substances attached to the sink roll 100 and the stabilizing roll 200, the sink roll 100 and the stabilizing roll 200 are cleaned using the above-described apparatus. Specifically, in the embodiment of the present application, the base plate 10 of the apparatus is fixed to the sink roll 100 and the stabilizing roll 200 by a fixing bracket, respectively, and then the blade tip of the first blade 32A is moved into contact with the sink roll 100 by the first telescopic mechanism, and the blade tip of the second blade 32B is moved into contact with the stabilizing roll 200 by the second telescopic mechanism, and then the sink roll 100 and the stabilizing roll 200 are rotated with respect to the first blade 32A and the second blade 32B to scrape off foreign substances attached to the surfaces of the sink roll 100 and the stabilizing roll 200.
further, referring to fig. 3, in the embodiment of the present application, the first driving element 40 and the second driving element 50 of the apparatus are electrically connected to the control panel 300. The control panel 300 includes a controller (such as a programmable logic controller PLC, etc.), and through the control panel 300, the first driving element 40 (i.e., a variable frequency motor) can be controlled to drive the rack 30 to move left and right, and the second driving element (i.e., the pneumatic control valve station 50) can be controlled to drive the telescoping mechanism 31 (i.e., an air cylinder) to extend up and down, so as to control the scraper 32 to move up and down and left and right.
also considering the problem of dust prevention and the problem of heat dissipation, in an embodiment of the present application, the control panel 300 may further adopt a dust prevention structure and a ventilation and heat dissipation structure, such as installing a heat sink or providing a dust prevention ventilation opening.
with continued reference to fig. 3, in the present embodiment, the pneumatically controlled valve station 50 includes a pressure gauge 51 by which the contact pressure between the doctor blade 32 and the work roll can be detected 51. Therefore, in the embodiment of the present application, the contact pressure between the doctor blade 32 and the work roll can be adjusted according to the data detected by the pressure gauge 51, so that the phenomenon that the resistance of the doctor blade 32 to the work roll is too large to affect the normal rotation of the work roll is avoided.
Further, with reference to fig. 3, in the embodiment of the present application, two ends of the guide rail 20 of the apparatus are respectively provided with a travel switch, and the travel switches are electrically connected to the control panel 300, when the rack 30 moves to two ends of the guide rail 20, a control signal can be triggered by the travel switches and transmitted to the control panel 300, and after the control panel 300 receives the control signal, the inverter motor can be controlled to be powered off or rotate reversely.
Optionally, in the embodiment of the present application, the device may be set to a manual control mode or an automatic control mode. In the manual control mode, the operator can control the first and second blades 32A and 32B to move to the designated positions according to the requirement to clean the sink roller 100 and the stabilizing roller 200. In the automatic mode, it may be configured to automatically control the first scraper 32A and the second scraper 32B to perform a cyclic reciprocating motion, specifically, from when the scraper 32 moves to one end of the work roll, the frame 30 is driven to move in a reverse direction by the variable frequency motor, or the cylinder is controlled to retract by the pneumatic control valve station 50, and then the frame 30 is controlled to return to the other end to clean the work roll again.
Besides, in the embodiment of the present application, an alarm signal indicator lamp may be further disposed on the control panel 300, and when a fault such as a scraper frequency converter trip, a motor overload, or a travel switch failure occurs, the alarm signal indicator lamp may prompt a relevant worker. Similarly, before the system is operated, a worker can observe whether the system is normal or not according to the indicator lamp, so that the system is prevented from working under the condition of faults.
Optionally, in other embodiments of the present application, an additional control function may be added on the basis of the above-mentioned embodiments, for example, an emergency stop button, a mode switching button, etc., which are not specifically limited herein.
