Online deviation rectifying and material pressing assembly for material roll unwinding

Abstract

The invention discloses an online deviation rectifying and pressing assembly for material roll unwinding. The online deviation rectifying and pressing assembly comprises a mounting plate with a mounting seat on one side, a sliding seat which slides in the thickness direction of the mounting plate and is driven by a power device is arranged on the mounting seat, a material shaft driven by a transmission mechanism is rotatably mounted on the sliding seat, a receding hole is formed in the position, corresponding to the material shaft, of the mounting plate, and the material shaft passes through the receding hole and extends to the other side of the mounting plate; and a rotating seat is arranged on the mounting plate on one side of the receding hole, a rotating shaft driven by a driving device is rotatably mounted on the rotating seat, a material pressing mechanism is arranged on the rotating shaft, and the material pressing mechanism and the extending end of the material shaft are arranged on the same side of the mounting plate. On-line adjustment of the working position of a material coil is achieved, namely on-line deviation rectifying of a material belt during unwinding is achieved, and working continuity and working efficiency are guaranteed; during discharging, a material roll cannot swing back and forth, the discharging stability is high, the tension of a material belt is constant, and the problem of damage caused by the change of the tension of the material belt is avoided; and meanwhile, the noise during discharging is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of roll material unwinding, and in particular relates to an online deviation correcting and pressing assembly for unwinding a material roll. Background technique [0002] At present, the unwinding method for roll materials is as follows: fix the roll on the rotating support shaft or air expansion shaft, apply traction force to the material tape on the roll through the downstream traction mechanism, and then complete the unwinding. Material work, there are the following problems in the process of the above-mentioned discharging: [0003] 1. When the traction force of the traction mechanism changes or the traction is stopped, the rotating material roll support shaft or air expansion shaft will drive the material roll to swing back and forth due to inertia, and the stability of the discharge is poor; at the same time, the material belt between the material roll and the traction mechanism The tension will chang...
