Belt Unit Tilting Steering Roller for Lateral Shifting Correction

The invention changes the movement direction of the steering roller from solely perpendicular to the bisector of the wrapping angle to a direction that includes a component along the bisector. This dimensional change in the tilt trajectory enables the smaller steering roller to effectively correct lateral shifting by utilizing both perpendicular and longitudinal movement components, thereby maintaining correction performance despite reduced roller diameter.

The invention changes the movement parameters of the steering roller by defining a new tilt direction that combines perpendicular and longitudinal components. This parameter modification allows the reduced-size steering roller to achieve the necessary belt repositioning capability that would be insufficient with traditional perpendicular-only movement, thus resolving the contradiction between size reduction and performance maintenance.

By introducing a longitudinal movement component to the steering roller's tilt direction, the invention distributes belt tension more evenly across the belt width. This dimensional change in movement trajectory prevents concentrated stress points that would occur with traditional perpendicular-only movement, thereby reducing belt damage risk even with a smaller, less material-intensive steering roller.

The invention modifies the movement parameters of the steering roller to include both perpendicular and longitudinal components. This parameter change optimizes the force distribution across the belt, preventing excessive localized tension that could damage the belt while using less material in the steering roller itself.

The invention enhances the lateral shifting correction capability of the smaller steering roller by adding a longitudinal movement component to its tilt direction. This dimensional enhancement allows the compact, easier-to-install roller to achieve effective belt repositioning that would be insufficient with traditional perpendicular-only movement, thus maintaining correction capability despite reduced size.

By changing the movement parameters of the steering roller to include both perpendicular and longitudinal components, the invention enables the smaller, more easily installed roller to achieve the necessary lateral shifting correction performance that would be inadequate with traditional movement patterns.
