Description

Cleaning device for finishing and automatically polishing cold-rolled steel plate Technical Field The present invention relates to a cleaning device, and more particularly, to a cleaning device for a surface of a steel sheet. Background In the current production process, the cold-rolled steel sheet needs to be polished on line after finishing. The existing online grinding machine does not consider the problem of cleaning the surface of the strip steel after grinding. The prior art adopts a manual cleaning mode to clean the surface of the polished strip steel. However, manual cleaning is performed by manpower, and an operator cleans according to the requirement of the management process, and when the operator is relaxed or does not comply with the requirement of standardized operation, the operator can feel unclear. In addition, manual cleaning has a certain work load and can occur in areas where wiping is missed. When the steel sheet face is wider, personnel's arm just can not be to another one side face, needs to stand in belted steel both sides and goes on, and on the one hand makes a round trip to run the wave inefficiency, and on the other hand still probably appears leaking the position of wiping, leads to operating efficiency low. Disclosure of Invention One of the purposes of the invention is to provide a cleaning device for automatically polishing a cold-rolled steel plate after finishing, which can automatically clean the polished strip steel surface by mechanical equipment independent of manpower, thereby greatly improving the production efficiency and the steel plate surface quality. In order to achieve the above object, the present invention provides a cleaning device for a cold rolled steel sheet after finishing and automatic polishing, comprising: A bracket including a support column provided in a height direction; The cleaning assembly is correspondingly arranged on the supporting upright post, and each cleaning assembly comprises a cleaning frame, a wiping roller, a cleaning roller and a cleaning roller, wherein the cleaning frame extends along the width direction of the strip steel; At least one connecting shaft which is correspondingly connected with the cleaning frame, the axial direction of the connecting shaft is consistent with the height direction of the supporting upright post, and the connecting shaft is also connected with the corresponding supporting upright post in a sliding way; at least one first driving element connected with the connecting shaft to drive the connecting shaft to rotate around the self axis so as to drive the cleaning assembly to switch between an opening station and a closing station; At least one second driving element connected with the connecting shaft to drive the connecting shaft to slide along the height direction of the support upright so as to switch the cleaning assembly between the standby station and the cleaning station; When the second driving element drives the connecting shaft so that the cleaning assembly is positioned at the cleaning station, and the first driving element drives the connecting shaft so that the cleaning assembly is positioned at the closing station, the wiping roller presses against the strip steel to clean the surface of the strip steel. Further, in the cleaning device according to the present invention, the cleaning assembly has two pairs, and accordingly, the connecting shaft, the first driving member, and the second driving member are each provided with two pairs. Further, in the cleaning device of the present invention, the cleaning frame includes: A mounting arm; the mounting bracket is hung on the mounting arm through a hanging shaft, and the wiping roller is arranged on the mounting bracket; And the spring is sleeved outside the hoisting shaft and is arranged between the mounting arm and the mounting bracket so as to apply elastic force for keeping the mounting bracket away from the mounting arm. Further, in the cleaning device of the present invention, the cleaning assembly further includes: a wiping cloth shaft which is rotatably arranged on the cleaning frame and is arranged above the wiping roller in parallel with the axial direction of the wiping roller, and a coiled wiping cloth is sleeved on the wiping cloth shaft; A recovery shaft rotatably provided on the cleaning frame and provided between the wiping roller and a wiping cloth shaft in parallel with an axial direction of the wiping roller, the wiping cloth being wrapped around an outer circumferential surface of the wiping roller and wound around the recovery shaft; And a third driving element connected with the recovery shaft to drive the recovery shaft to rotate around the self axis.
