Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyors, and more specifically, it relates to a driven roller for a belt conveyor. Background Technology

[0002] A belt conveyor is a mechanical device that uses a continuously moving conveyor belt as a traction and load-bearing component to transport materials or items in a certain direction. It is one of the most commonly used continuous conveying equipment in modern industrial production and is widely used in mining, metallurgy, chemical industry, power, building materials, ports, food processing and many other fields.

[0003] Driven rollers are a commonly used component in belt conveyor installation. However, there are some problems with driven rollers in practical applications. After installation, nut rings must be used to limit the two ends of the shaft to ensure the normal operation of the driven roller. However, since the nut rings rotate with the shaft, they may loosen after long-term use. This will affect their limiting effect on the shaft. Under the tension of the conveyor belt, the driven roller may move axially. This will cause problems in the fit between the roller and the shaft, frame and other components, increasing the risk of wear and failure, and may even damage the roller, thus affecting the service life of the belt conveyor. Therefore, improvements are needed. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a driven roller for a belt conveyor, which has the advantage of good limiting effect on the rotating shaft.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A driven roller for a belt conveyor includes a rotating shaft, a round rod is movably sleeved inside the rotating shaft, a rectangular block is fixedly connected to the right side of the round rod, a circular block is fixedly connected to the left side of the round rod, the outer surface of the circular block is movably connected to the outer side of the rotating shaft, a spring is fixedly connected to the left side of the rectangular block, the other end of the spring is fixedly connected to the inner wall of the rotating shaft, a connecting rod is hinged to the right side of the rectangular block, a moving block is hinged to the other end of the connecting rod, and the outer surface of the moving block is movably connected to the inner surface of the rotating shaft.

[0006] As a preferred embodiment of this utility model, a handle is fixedly connected to the outer side of the circular block, and the handle is U-shaped.

[0007] As a preferred embodiment of this utility model, the rotating shaft has a sliding groove inside, and a limiting block is movably connected to the inner surface of the sliding groove. The left side of the limiting block is fixedly connected to the right side of the moving block.

[0010] As a preferred embodiment of this utility model, the top of the circular block is provided with a circular hole, the diameter of which is the same as the diameter of the connecting block.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, this utility model provides a driven roller for a belt conveyor, including a rotating shaft 1. A round rod 3 is movably sleeved inside the rotating shaft 1. A rectangular block 4 is fixedly connected to the right side of the round rod 3, and a circular block 5 is fixedly connected to the left side of the round rod 3. The outer surface of the circular block 5 is movably connected to the outer side of the rotating shaft 1. A spring 6 is fixedly connected to the left side of the rectangular block 4, and the other end of the spring 6 is fixedly connected to the inner wall of the rotating shaft 1. A connecting rod 7 is hinged to the right side of the rectangular block 4, and a moving block 8 is hinged to the other end of the connecting rod 7. The outer surface of the moving block 8 is movably connected to the inner surface of the rotating shaft 1. Due to the elastic recovery effect of the spring 6, the round rod 3, the rectangular block 4, and the circular block 5 will move inward, thereby causing the two connecting rods 7 to rotate and drive the two moving blocks 8 to move in opposite directions. With the cooperation of the mounting frame, the installation and limiting function of the rotating shaft 1 is achieved.

[0022] The circular block 5 is fixedly connected to a handle 9 on its outer side. The handle 9 is U-shaped. The design of the handle 9 makes it easy for the operator to pull the handle 9 to move the circular block 5 outward.

[0023] The rotating shaft 1 has a sliding groove 10 inside, and a limiting block 11 is movably connected to the inner surface of the sliding groove 10. The left side of the limiting block 11 is fixedly connected to the right side of the moving block 8. The design of the sliding groove 10 and the limiting block 11 serves to limit the movement of the moving block 8 and ensure the stability of the horizontal movement of the moving block 8.

[0024] Among them, the outer surface of the rotating shaft 1 is fixedly sleeved with the driven roller body 12, and the outer surface of the driven roller body 12 is rough; the rough design of the outer surface of the driven roller body 12 can prevent the conveyor belt from slipping on the surface of the driven roller body 12.

[0025] Among them, the outer side of the rotating shaft 1 is fixedly connected to a fixing block 13 located directly above the circular block 5. The fixing block 13 is internally threadedly connected to a threaded rod 14. The bottom of the threaded rod 14 is fixedly connected to a connecting block 15. The top of the connecting block 15 is movably connected to the bottom of the fixing block 13. The design of the fixing block 13 serves to support and stabilize the threaded rod 14.

[0026] The circular block 5 has a circular hole 2 at its top, and the diameter of the circular hole 2 is the same as the diameter of the connecting block 15. This design allows the connecting block 15 to be inserted into the circular hole 2 to fix the circular block 5 as a whole, making it easy for operators to quickly install and remove the rotating shaft 1.

[0027] There are four movable blocks 8, all of the same size, and they are symmetrical about the center of the rotating shaft 1. The design of the four movable blocks 8 provides better installation and limiting effect at both ends of the rotating shaft 1, ensuring the stability of the rotating shaft 1 when it rotates.

[0028] Working principle and usage process of this utility model:

[0029] When installing the limiters at both ends of the rotating shaft 1, first pull the two handles 9, which will drive the two round rods 3, the two rectangular blocks 4 and the two circular blocks 5 to move outward, thereby causing the four connecting rods 7 to rotate and drive the four moving blocks 8 to move towards each other in pairs. When the four moving blocks 8 move into the interior of the rotating shaft 1, the circular hole 2 corresponds to the connecting block 15. Then rotate the two threaded rods 14 downward, which will drive the two connecting blocks 15 to move downward and insert into the interior of the two circular holes 2 to fix the two circular blocks 5.

[0030] Subsequently, the rotating shaft 1 and the driven roller body 12 are installed. After the rotating shaft 1 and the driven roller body 12 are installed, the two threaded rods 14 are rotated upward again, which will drive the two connecting blocks 15 to move upward and separate from the two round holes 2, thus releasing the fixing effect on the two round blocks 5. At this time, under the elastic recovery action of the two springs 6, the two round rods 3, the two rectangular blocks 4 and the two round blocks 5 will move inward, thereby causing the four connecting rods 7 to rotate and drive the four moving blocks 8 to move in opposite directions. At the same time, with the cooperation of the frame, the installation limit function of the two ends of the rotating shaft 1 is realized, ensuring the stability of the driven roller body 12 during operation.
