Hydraulic Self-Aligning Idlers SXBMD-JP-Y

1. Working Principle

The device is composed of a power output device consisting of a testing wheel and a oil pump, a logic valve and an oil cylinder, and then connected with the self-aligning idlers bracket.

It is normal operation when the belt moves in the middle and does not contact to the two testing wheels. If the belt runs to the left, the left power output device get started, the actuator will adjust the rectifying roller position according to the judgement of logical valve to generate a reverse thrust, and push the belt to the middle. Contrarily, if the belt runs to the right, the right power output device get started, the actuator will judge the rectifying roller position according to the judgement of the logical valve to generate a reverse thrust, push the belt to the middle. The idlers make the belt always running in the setting width range, avoid belt tearing, machine halt, material sprinkling due to the belt deviation, ensuring the normal running of the conveyor.

2. Features and advantages

(1) Suitable for one-way or two-way running belt, with better adaptability;

(2). The whole frame (rotating beam and supporting beam) is made of high-strength square steel, with high strength, wide application range, easy installation and stable operation;

(3) Suitable for the working place requiring sensitive deviation correction, with difficult daily maintenance and severe working environment.

Self-Aligning Idlers SXBMD-JP-JX

1. Working Principal

The preset type belt automatic self-aligning idlers are composed by vertical roller mechanism, roller mechanism and link mechanism, when the belt running in deviation, the belt edges will push the vertical roller moving towards the deviation direction of the belt , the vertical rod in the vertical roller will move at the same time, the vertical rod will drive the roller mechanism to deflect simultaneously, the linear motion direction of the deflection roller and the belt running direction will form an angle, the resulting lateral friction will drive the belt to move in the middle.

2. Features and advantages

(1). The rotating joint design with dry bearing makes the idlers prevent from the invading of water, coal

slime, dust and other materials, only need simple installation, no daily maintenance required;

(2) No power drive needed, the operating mechanism is low pair linkage with short movement distance,

Thus the idlers low wearing and long service life;

(3).The rollers used in the idlers is the upper roller of the on-line belt conveyor, the user only need to replace

their own rollers in-use once the roller is broken, thus reducing the downtime;

(4) The self-aligning idlers have many excellent performances, such as no external power supply needed,

sensitive reaction, high rectifying efficiency, easy installation and maintenance, lower labor cost, longer

service life, higher cost-benefit, improved production safety, etc.
