Conveyor Drive Roller

technical field

The utility model belongs to the field of conveying equipment, in particular to a conveyor driving roller.

Background technique

Belt conveyor is a continuous operation of transportation equipment, mainly used in metallurgy, mining, power, building materials and other heavy industry departments and transportation departments to transport a large number of bulk goods, such as ore, coal, sand and other powder, lumps and packaging Good finished item. Belt conveyor is the most ideal high-efficiency continuous transportation equipment for coal mines. Compared with other transportation equipment, it not only has the advantages of long distance, large capacity, and continuous transportation, but also has reliable operation and is easy to realize automation and centralized control. In high-yield and high-efficiency mines, belt conveyors have become the key equipment for high-efficiency coal mining mechatronics technology and equipment. Especially in the past 10 years, the emergence of long-distance, large-capacity, and high-speed belt conveyors has further promoted its application in mine construction underground roadways, mine surface transportation systems, open-pit mines, and mineral processing plants. .

As an important part of the belt conveyor, the drum is the main part of the torque transmission, and its performance directly affects the performance of the belt conveyor. The interaction between the conveyor roller and the belt is very complicated. The interaction between the pressure, static friction and dynamic friction of the belt, as well as the creep of the belt caused by elastic elongation at the roller, make it difficult to accurately express the force on the roller. This is The design of the belt conveyor brought a lot of trouble.

The outer wall of the connecting ring is closely attached to the inner wall of the reinforcing ring and is fixedly connected with the reinforcing ring. The cross section of the inner ring of the connecting ring is stepped.

As a preferred solution of the present utility model, the drum skin includes an inner skin, an outer skin and a sealing ring. The outer skin is placed outside the inner skin and is sealed and connected with the inner skin through the sealing ring. An anti-skid layer is arranged on the upper part, and anti-skid lines are arranged on the anti-skid layer.

As a preferred solution of the present utility model, several air extraction holes are arranged on the cylinder wall of the outer skin, the air extraction holes are located between the rubber layer and the anti-skid layer, and the interlayer formed by the inner skin and the outer skin forms an air extraction cavity, and on the side of the sealing ring It is equipped with a suction pipe.

The utility model has the advantages of the transmission roller of the conveyor belt, which has good friction with the conveyor belt and prevents the roller from slipping. At the same time, the integrity of the roller is good, and it has a good twisting effect, which prevents the roller width from being stretched when the roller load is too large. The board is warped.

detailed description

As shown in the accompanying drawings, the conveyor drive roller of the utility model includes a roller skin 1, a web 2, a wheel hub 3 and a main shaft 4. Two webs 2 are arranged at intervals in front and rear of the interior of the drum skin 1, and in the middle of each web 2 Each is provided with a hub 3 , the main shaft 4 passes through the hub 3 and is fixedly connected to the hub, and a reinforcement assembly is arranged between the drum skin 1 and the web 2 .

When the main shaft 4 rotates, it drives the wheel hub 3, the web 2 and the drum skin 1 to rotate synchronously, thereby driving the conveyor belt wound outside the drum to carry out the operation. By arranging a reinforcing component between the drum skin and the web, it can prevent the web from being twisted and deformed when the drum is overloaded, prolonging the service life of the drum.

The reinforcement assembly includes a reinforcement ring (5), the outer wall of the reinforcement ring (5) is attached to the inner wall of the drum skin (1), and an annular groove is provided inside the reinforcement ring (5) for snapping in the web, and the web (2 ) is snapped into the annular groove, a collar (6) is provided on the left and right sides of the outside of the reinforcing ring (5), and a card groove matching the collar is provided on the inner wall of the drum skin (1) , the collar (6) snaps into the card slot, and a connecting ring (7) is arranged on the left and right sides of the web (2), the outer wall of the connecting ring (7) is closely attached to the inner wall of the reinforcing ring (5) and It is fixedly connected with the reinforcing ring, and the section of the inner ring of the connecting ring (7) is stepped.

Since the inside of the reinforcement ring is provided with an annular groove for the panel to be inserted into, the edge of the panel is inserted into the annular groove, and the clip rings on both sides of the outer sides of the reinforcement ring are inserted into the slot, so that the panel, reinforcement The ring and the drum skin are fixedly connected together, and the web 2 located in the middle of the two connecting rings 7 can be protected by setting the connecting ring 7 to play a supporting role.

The drum skin 1 includes an inner skin 1-1, an outer skin 1-2 and a sealing ring 1-3. The outer skin 1-2 is placed outside the inner skin 1-1 and is sealed with the inner skin through the sealing ring 1-3. 2. A rubber layer 1-4 is provided in the middle part of the outside, and an anti-slip layer 1-5 is provided on the left and right parts outside the outer skin 1-2, and an anti-slip pattern 1-6 is provided on the anti-slip layer 1-5.

The rubber layers 1-4 can increase the contact between the conveyor belt and the roller skin, so that the roller skin and the conveyor belt are in close contact, thereby increasing the friction. The anti-slip pattern can further increase the friction between the conveyor belt and the roller skin to prevent slipping.

A number of air suction holes 1-7 are provided on the cylinder wall of the outer skin 1-2.
