A rolling device for automotive trim strips

By introducing a movable connecting inner frame and rotating bolts into the automotive trim strip roller pressing device, the problem of the existing device being unable to adjust the roller spacing is solved, enabling adaptability to trim strip raw materials of different thicknesses. This ensures that the pressure rollers can flexibly set the appropriate roller spacing according to the actual thickness of the trim strip raw materials used, solving the problem of not being able to apply uniform pressure to trim strips of different thicknesses in the existing technology, improving production efficiency and product quality consistency, and reducing production costs.
