The apparatus includes (1) a frame formed with a trough hole and a slot; (2) a motor obliquely attached to a side wall of the frame; (3) a rear roller positioned in the slot and operably coupled to the motor by a driving gear; (4) a front roller positioned in the slot and operably coupled to the rear roller via a transmission gear set; and (5) a cam component operably attached to the frame and positioned adjacent to the front roller. When the cam portion is rotated, the front roller is moved toward or far away from the rear roller.
