Technical Field

[0001] The utility model relates to the technical field of exposure, in particular to an automatic position deviation correction device for wide-width materials. Background Art

[0002] During the processing and transmission of flexible materials, the material is prone to deviation due to uneven force, resulting in Y-direction deviation at the point to be processed.

The surface of the width adjustment plate 5 is fixedly connected to the linear bearing retaining ring 51. The first linear bearing is fixedly installed on the inner wall of the linear bearing retaining ring 51 by a first side screw. The linear guide shaft 52 passes through the inner ring of the first linear bearing and the two ends of the linear guide shaft 52 are fixedly connected to the second mounting plates 2 on both sides, respectively. After the spacing adjustment of the two width adjustment plates 5 is completed, the second side screw is tightened to fix the position of the width adjustment plate 5, wherein the second side screw passes through the linear bearing retaining ring 51 and the end thereof abuts against the surface of the linear guide shaft 52.

[0025] The driving roller 4 includes a roller core 41 and a hollow roller 42. The roller core 41 is sleeved on the inner side of the hollow roller 42 and the end of the roller core 41 is fixedly connected to the second mounting plate 2.
