Bulk material conveying equipment

Belt conveyor is one of the most important modern equipment for conveying bulk materials, widely used in many fields. Its conveying capacity, efficiency, and operational safety factor have a significant impact on the development of China's national economy. As for the transmission drum of belt conveyor, firstly, in the early stage of drum research, people followed the previous design concept and used thicker steel plates to increase the bearing capacity of the drum. However, the result of this was that many equipment's drums cracked. Secondly, later people turned their attention to flexible drums, considering the cyclic stress on the drum in their design and adopting a coating layer on the drum surface to achieve flexibility;

A practical tape machine transmission drum designed by industry engineers, which is equipped with a strong suction cup. During its rotation, the vacuum degree generated by the suction cup can be used to increase the radial force between the conveyor belt and the drum body, thereby increasing the frictional force between the two and improving the overall conveying capacity of the equipment. It includes a drum body and a drum shaft. A vacuum suction cup device is installed inside the drum body, which includes several suction cups. Each suction cup is tightly attached to the inner wall of the drum body, and rotates with the drum body. A ventilation hole connected to the suction cup is set on the drum wall in contact with the suction cup;

The suction cup, which rotates with the drum body to the enclosed angle range formed by the circular conveyor belt and the drum body, generates a certain degree of vacuum under the action of the electromagnetic driving action structure. Through the ventilation hole, additional force is generated between the belt and the drum body coating layer, which tightens the two and increases the radial pressure between the rubber belt and the drum body, thereby increasing the friction force. As the transmission drum continues to rotate, the suction cup group controls the electromagnetic part to cut off power when it rotates out of the enclosed angle range. The magnetic action is released, and under the action of the tension spring, the suction disc is reset, and the vacuum degree disappears, ensuring smooth separation between the nylon rubber belt and the drum body, avoiding energy consumption. This mechanism will make the belt conveyor operate more efficiently. Stable transmission ratio and significantly improved conveying capacity;
