Introduction to belt pulley of conveyor:

Belt pressing pulley is widely used in belt conveyor and large inclination belt conveyor. Its function is to press on the working face of skirt belt (conveyor belt) to change the running direction of skirt belt (conveyor belt).

The belt pressing pulley of the belt conveyor includes a wheel frame installed on the middle frame of the belt conveyor. The wheel frame is equipped with two fixed mandrel, and each fixed mandrel is equipped with a wheel. The utility model has the advantages of simple and light structure, convenient installation, and can be placed in the general rainproof cover; The high angle belt pressing wheel is suitable for materials with unit mass of 500 ~ 2500kg / m3 and bulk degree of about 100 ~ 250mm; The utility model has the advantages of simple structure, convenient maintenance, small occupied space and investment saving (this model can be directly selected instead of the combined layout of conveyor and bucket elevator), convenient layout, etc. Although the belt pressing pulley does not appear on the conveyor equipment as a main component, if used properly, it can help the conveyor operate and produce better.

A good belt pressing wheel has a flat surface and a matte effect, otherwise it will affect the belt walking accuracy of the movement, and the signal distortion is caused by the excessive shaking rate. In addition, it should be noted that whether the daily maintenance of the card holder is appropriate or not will also affect the service life of the movement. The belt pressing wheel is a rubber product. It is easy to age when it is usually cleaned with alcohol and other chemicals. It can only be gently wiped with a cotton swab dipped in a little purified water. The ambient temperature should not be higher than 30 degrees Celsius.

Structure composition of belt pulley of conveyor:

The belt pressing wheel is composed of rim, shaft and bearing seat. If it is used on a large inclination belt conveyor, the rim can be a compound rim, and the inside can be close to the skirt.

Selection method of belt pulley of conveyor:

From the perspective of use, the adverse effects of belt pressure pulley are wear, dynamic load impact, etc., so we need to select the materials that can absorb dynamic load. Moreover, this kind of parts are vulnerable and perishable parts, which must be processed in batch. Casting is good from the perspective of cost, so you can choose cast steel in the metal manual, and then comprehensively consider and absorb materials with strong dynamic load.

Qualitative analysis of belt pulley of conveyor:

When designing a belt conveyor with concave arc section, it is usually necessary to consider the small curvature radius of the concave arc section conveyor belt. Only when the appropriate curvature radius is, the conveyor belt will not lift up due to large tension and separate from the idler to cause material scattering. This problem can be solved if the structural form of changing direction pressing wheel is adopted.

The reversing roller acts on both sides of the conveyor belt to force the conveyor belt to bend its running direction. During no-load operation, the conveyor belt here becomes flat under its tension. After feeding, due to the self weight of materials, the conveyor belt will also form a groove, and materials will not be scattered outside.

Application scope of conveyor belt pulley:

Belt pulley is widely used in building materials, construction, chemical industry, thermal power, grain processing, mining, machinery, metallurgy, transportation, port and transportation.
