Roller conveyor has good versatility, can be used to transport all kinds of objects with flat bottom, such as plate, bar, tube, tray, box container workpiece. The width of the goods can be allowed to change in a large range, generally acting on the straight section of the roller conveyor, can also be used for arc section.

Roller is an important part of conveying machinery equipment. The production of roller is mainly composed of roller body initial turning, initial static balance calibration, shaft head interference assembly welding, fine dynamic balance calibration other process groups, which are widely used in various packaging, conveying, sorting conveying equipment. After the roller is formed, for the needs of anti rust, anti-corrosion, support wear resistance, the surface treatment coating, such as painting, gluing, chromium plating oxidation, are also needed.

The quality of roller directly affects the normal operation operation cost of conveyor. Roller can be divided into ordinary bearing roller special roller according to different uses. The ordinary bearing roller is the upper lower branch roller in the normal section, which is used to support the conveyor belt materials; the special roller is used to guide the transition of the conveyor belt, prevent the deviation of the conveyor belt buffer the conveyor belt. The rollers are installed on the conveyor in groups. The basic requirements for the roller group are: reliable use, small rotary resistance coefficient, low manufacturing cost, sufficient bearing capacity. The distance between rollers should meet the two conditions of roller bearing capacity belt sag. When the roller needs to be densified due to excessive force, the distance between rollers can be determined by the designer according to the actual needs.

The roller conveyor limits the inertia force increases the braking torque

1. Improve the sensitivity of the sensor reduce the delay time. In this way, it is necessary to improve the quality of the components adjust the relative position of the sensor the conveyor belt.

2. Using the car brake with fast response, usually the action of electromagnetic brake is fast.

3. the brake with braking torque, the clearance between brake shoe brake wheel shall be adjustable.
