Conveyor Tensioner Spiral Tensioner

(1) The tension force is small and the tension stroke is short; The adjustment capacity of the screw tension device mainly depends on the size and length of the screw diameter, because it is installed on the tail wheel frame, limited by the tail wheel support, the screw diameter and length are generally not large, so the tension stroke is short, the tension force is also small, not suitable for installation on the long distance belt conveyor with the tension force.

(2) Simple structure and easy operation; When you need to tighten the tape, just use a wrench to rotate the screw, easy to operate, fast, small labor intensity, high efficiency. For belt conveyors with slight deviation, the belt deviation can be adjusted by rotating the screw on one side and adjusting the parallel Angle between the tail wheel and the head wheel.

(3) Small installation size, make full use of space; Screw and nut dimensions are usually small, manufacturing difficulty is small, easy processing, and installed on the tail wheel support, make full use of space, save the area of the equipment, so the whole machine cost is low.

(4) Low operating cost; Because the screw has self-locking characteristics, its use performance is stable and reliable, and good adaptability to the external environment, long service life, even in the dust, mud and water can be used normally under harsh conditions. The spare parts of the tension device are not expensive, the maintenance and replacement time is short, and the labor intensity of the maintenance workers is small, so the efficiency is high and the operating cost is low.
