[0002] The strip shear width adjustment mechanism is an important component of the shearing equipment. It can adjust the shear width of the strip according to different shearing requirements. The strip shear width adjustment mechanism traditionally used in shearing equipment usually consists of the following parts: 1) Adjustment motor: through the rotation of the motor, the adjustment device is driven to move to achieve the adjustment of the shear width. 2) Adjustment rod: connects the adjustment motor and the shear blade, converts the rotational motion of the motor into linear motion, and drives the shear blade to move horizontally. 3) Limiting device: used to limit the movement range of the adjustment rod to ensure that the shear blade will not be damaged due to excessive movement.
