Abstract
The utility model discloses an underground rewinder clamping roll device capable of adjusting deflection distance. The utility model is provided with two clamping rolls on the upper and the lower ends, and a supporting mechanism of at least one clamping roll is connected with a machine frame in an adjustable mode. The supporting mechanism of the clamping roll is adjusted through a deflection distance adjusting mechanism to cause the two clamping rolls to make parallel relative displacement in the horizontal direction to form different deflection distances to cause the steel strips of different thicknesses to form an approximately same bend radius, and consequently, the steel strips can be nicely wound on a reel drum. Especially, the strip steel head can easily enter between the reel drum of the rewinder and a number 1 auxiliary reel roller to avoid or lighten the impact of the strip steel head to the reel drum of the rewinder, a guide plate and the auxiliary reel roller.
