Description

Technical Field

[0001] The present application relates to the technical field of conveyor belts, and in particular to an anti-static conveyor belt. Background Art

[0002] Conveyor belts, also known as transport belts, are composite products of rubber, fiber, metal, or plastic and fabric used in belt conveyors to carry and transport materials. Conveyor belts are widely used in cement, coking, metallurgy, chemical, steel and other industries where the conveying distance is short and the conveying volume is small.

[0003] The existing patent (announcement number: CN208516252U) discloses a rubber-plastic antistatic conveyor belt, which includes an antistatic rubber layer, a canvas layer and an industrial fiber layer. The canvas layer is divided into a first canvas layer, a second canvas layer and a third canvas layer. The industrial fiber layer is located between the second canvas layer and the third canvas layer. The first canvas layer, the second canvas layer, the industrial fiber mesh and the third canvas layer are tightly compounded in sequence through the antistatic rubber layer. The utility model makes the canvas layer and the industrial fiber layer tightly bonded through the antistatic rubber layer, so that the conveyor belt will not generate static electricity during operation, effectively avoiding the occurrence of danger. At the same time, the industrial fiber mesh inside the conveyor belt can enhance the strength of the conveyor belt. The conveyor belt is resistant to tension, wear and static electricity.

[0004] During use, the above-mentioned document improves the antistatic property of the conveyor belt by setting the material, but after long-term use, the antistatic effect will be weakened due to material wear. The existing antistatic conveyor belt has weak wear resistance. After a period of use, the antistatic effect is greatly reduced and needs to be replaced frequently, which increases production costs.

[0022] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0023] For this anti-static conveyor belt, by installing the first exhaust pipe, the first air nozzle, the second exhaust pipe, and the second air nozzle, positive and negative ion gases can be sprayed at the connection between the driving roller and the conveyor belt body, enabling the static electricity between the driving roller and the conveyor belt body to be neutralized.

[0030] Please refer to Figure 1 , Figure 2 , A rotating rod 10 is rotatably connected to the inner wall of the machine body 1. A plurality of brushes 11 distributed in a circular pattern are fixedly connected to the outer surface of the rotating rod 10. The conveyor belt body 3 is in contact with the adjacent brush 11.

The conveyor belt body 3 is made of a polymer composite material, making it have excellent wear resistance and corrosion resistance, and can extend the service life of the conveyor belt.

[0031] Please refer to Figure 1 , Figure 2 , The machine body 1 is made of an insulating material. The machine body 1 being made of an insulating material can effectively prevent the generation and accumulation of static electricity and improve the overall anti-static property. A conductive grid 13 is installed on the outer surface of the conveyor belt body 3. The conductive grid 13 is made of conductive fiber material. Installing the conductive grid 13 can form a closed loop to conduct static electricity and improve the overall anti-static property. Two contact parts 14 are installed on the inner wall of the machine body 1. Both of the two contact parts 14 are in contact with the conductive fiber.
