Roller curvature measuring device

Abstract

The invention provides a roller curvature measuring device. The roller curvature measuring device comprises a telescopic assembly and a moving assembly. A supporting frame corresponding to the telescopic assembly is arranged on the moving assembly; the telescopic assembly is rotationally installed on the supporting frame close to the middle, and the two ends of the telescopic assembly can ascend and descend in the vertical direction, wherein one end of the telescopic assembly is connected with the radial run-out measuring instrument, and the other end is provided with contacts. According to the technical scheme provided by the embodiment of the invention, based on the lever principle, one end of the telescopic assembly is inserted into the heat preservation shell with the supporting frameas the fulcrum and abuts against the roller through the contact point, and the other end of the telescopic assembly measures the bending change through the radial run-out measuring instrument; therefore, the bending change of one end in the heat preservation shell can be obtained by measuring the outer end of the telescopic assembly, and then the bending change of the roller is obtained.

Description

technical field [0001] The present application relates to the technical field of float glass production, in particular to a roller curvature measuring device. Background technique [0002] Float glass melts and shapes the mixed batch materials and leaves the tin tank to enter the annealing furnace. The float glass transitions from the tin liquid to the running roller table and enters the annealing furnace (the furnace that reduces the glass temperature, mainly steel structure ) The circular rollers are uniformly arranged in the annealing furnace to carry the original glass sheet. The glass leaves the forming area and enters the annealing furnace. The requirements for the rollers carrying the glass in the annealing furnace are high, and the radial runout of the new rollers is required to be less than 0.2mm, but After the rollers bear the load, factors such as high temperature and gravity cause different degrees of bending of the rollers in different regions. When the bending ...

[0002] Float glass melts and shapes the mixed batch materials and leaves the tin tank to enter the annealing furnace. The float glass transitions from the tin liquid to the running roller table and enters the annealing furnace (the furnace that reduces the glass temperature, mainly steel structure ) The circular rollers are uniformly arranged in the annealing furnace to carry the original glass sheet. The glass leaves the forming area and enters the annealing furnace. The requirements for the rollers carrying the glass in the annealing furnace are high, and the radial runout of the new rollers is required to be less than 0.2mm, but After the rollers bear the load, factors such as high temperature and gravity cause different degrees of bending of the rollers in different regions. When the bending is too large, it will affect the lower surface of the glass, such as marks, scratches, etc., which seriously affect the quality of the lower glass plate. At present The method of detecting roll curvature is generally verified by accumulating experience and lowering, raising or replacing the rolls suspected of abnormal areas one by one. This method is time-consuming and labor-intensive, and affects the process during verification and adjustment.
