Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically a belt conveyor with buffering and shock absorption function. Background Technology

[0002] A belt conveyor is a mechanical device used for the continuous or intermittent transport of various materials. It is widely used in many industries such as mining, metallurgy, chemical industry, building materials, food processing, port loading and unloading, and logistics distribution. It transports goods via a circular, flexible conveyor belt, which is usually driven by a motor and rotates around a series of rollers.

[0003] When belt conveyors are in use, the equipment vibrates due to the movement of the motor or when materials fall onto the belt surface. Since traditional belt conveyors lack shock absorption structures, the vibration may cause materials to fall off the belt or cause equipment parts to loosen and fall off. Therefore, a belt conveyor with buffer and shock absorption function is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a belt conveyor with a buffer and shock absorption function, which can buffer the conveyor belt, improve the stability of the belt during operation, and make the conveyed material less susceptible to vibration and movement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor with buffering and shock absorption function, comprising a mounting frame, two rotating rollers mounted on the surface of the mounting frame, a drive motor fixed to the surface of the mounting frame, the output shaft of the drive motor fixedly connected to one side of the rotating roller, a conveyor belt mounted on the surfaces of the two rotating rollers, a separator fixed at the center of the surface of the mounting frame, an extension frame fixed at the bottom of the mounting frame, a plurality of first shock-absorbing blocks fixed at the bottom of the extension frame, support legs fixed at the bottom of the first shock-absorbing blocks, a plurality of first mounting plates fixed to the surface of the extension frame, a plurality of second shock-absorbing blocks fixed to the top of the first mounting plates, a first roller frame fixed to the top of the second shock-absorbing blocks, a first buffer roller rotatably connected to the surface of the first roller frame, a plurality of second mounting plates fixed to the top of the separator frame, a spring shock absorber fixed to the top of the second mounting plates, a second wheel frame fixed to the top of the spring shock absorber, a second buffer roller rotatably connected to the surface of the second wheel frame, a side block fixed to the top of the second mounting plate, and a buffer structure mounted on the surface of the side block.

[0006] As a preferred embodiment of the belt conveyor with buffering and shock absorption function of this utility model, a first airbag is fixed to the top of both the first mounting plate and the second mounting plate, and the bottom of the first roller frame and the second wheel frame are fixedly connected to the top of the first airbag.

[0007] As a preferred embodiment of the belt conveyor with buffering and shock absorption function of this utility model, the side block surface buffer structure includes a second air bladder, the second air bladder is fixedly connected to the side block surface, a slider is fixed to one end of the second air bladder, a rotating plate is hinged to the top of the slider, and the top of the rotating plate is hinged to the bottom of the second wheel frame.

[0008] As a preferred embodiment of the belt conveyor with buffering and shock absorption function of this utility model, the bottom of the slider is fixed with two side plates, and a movable roller is rotatably connected between the two side plates.

[0009] As a preferred embodiment of the belt conveyor with buffering and shock absorption function of this utility model, a telescopic flexible cover is fixed to the top of the second mounting plate, the top of the telescopic flexible cover is fixedly connected to the bottom of the second wheel frame, and buffer sleeves are fixed to the surfaces of the first buffer roller and the second buffer roller, the buffer sleeves being made of rubber.

[0010] As a preferred embodiment of the belt conveyor with buffering and shock absorption function of this utility model, the top of the mounting frame is fixed with two guide plates, and the guide plates are designed in a F-shape.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a design incorporating a first and second buffer roller. The first buffer roller absorbs vibrations from the conveyor belt itself, effectively suppressing vertical vibrations during operation, especially those caused by belt tension variations or uneven loads. This ensures smoother belt operation and accurate material transport. The first buffer roller contacts the top of the inner wall of the conveyor belt, immediately absorbing vibrations transmitted from it. The spring damper provides shock absorption, reducing direct impact of these vibrations on the mounting frame or other structures. Furthermore, this design allows the spring damper to mitigate overhead loads when material falls onto the conveyor belt, causing significant impact or vibration. Its elasticity and restoring force effectively absorb and disperse large vibration forces. This two-layer roller design achieves a multi-level shock absorption mechanism, significantly improving the vibration damping effect of the conveyor system and ensuring stability during material transport.

[0021] Please see Figure 1-7 A belt conveyor with buffering and shock absorption function includes a mounting frame 1, two rotating rollers 2 mounted on the surface of the mounting frame 1, a drive motor 3 fixed on the surface of the mounting frame 1, the output shaft of the drive motor 3 fixedly connected to one side of the rotating roller 2, a conveyor belt 4 mounted on the surface of the two rotating rollers 2, a separator frame 5 fixed at the middle position of the surface of the mounting frame 1, an extension frame 6 fixed at the bottom of the mounting frame 1, a plurality of first shock absorbers 7 fixed at the bottom of the extension frame 6, support legs 8 fixed at the bottom of the first shock absorbers 7, a plurality of first mounting plates 9 fixed on the surface of the extension frame 6, and a plurality of second shock absorbers 10 fixed at the top of the first mounting plates 9. The top of the shock absorber 10 is fixed with a first roller frame 11, and the surface of the first roller frame 11 is rotatably connected with a first buffer roller 12. The surface of the first buffer roller 12 is slidably connected with the bottom surface of the conveyor belt 4. The top of the separator 5 is fixed with multiple second mounting plates 13, the top of the second mounting plate 13 is fixed with a spring shock absorber 14, the top of the spring shock absorber 14 is fixed with a second wheel frame 15, the surface of the second wheel frame 15 is rotatably connected with a second buffer roller 16, the top of the second buffer roller 16 is slidably connected with the top of the inner wall of the conveyor belt 4, and the top of the second mounting plate 13 is fixed with a side block 19. The surface of the side block 19 is equipped with a buffer structure.

[0022] When the drive motor 3 starts, it can drive one side roller 2 to rotate. This side roller 2, in turn, can drive the other side roller 2 to rotate synchronously through the cooperation of the conveyor belt 4, realizing the movement effect of the conveyor belt 4 and enabling the conveyor belt 4 to transport materials. During the conveying process of the conveyor belt 4, the surface of the first buffer roller 12 can directly contact the bottom of the conveyor belt 4. The vibration generated by the conveyor belt 4 can be directly transmitted to the second damping block 10 through the first buffer roller 12, so that the first buffer roller 12 can absorb the vibration from the conveyor belt 4 itself, effectively suppressing the vertical jump of the belt during operation, especially the vibration caused by the tension change or uneven load of the conveyor belt 4, keeping the conveyor belt 4 running more smoothly and ensuring the accuracy of material transmission. The first buffer roller 12 can also work with the conveyor belt 4 to transport materials. The inner wall of the conveyor belt 4 is in contact with the top, which can immediately absorb the vibration transmitted from the conveyor belt 4. The spring damper 14 can dampen and buffer, reducing the direct impact of these vibrations on the mounting frame 1 or other structures. Through this design, when material falls on the surface of the conveyor belt 4, causing the conveyor belt 4 to be subjected to large impacts or vibrations, the spring damper 14 can use its elasticity and restoring force to mitigate the load from above, effectively absorbing and dispersing large vibration forces. Through this design of upper and lower two-layer idlers, a multi-level shock absorption and buffering mechanism is realized. This design can significantly improve the shock absorption effect of the conveying system and ensure the stability of material conveying. The first damping block 7 can reduce the vibration transmitted from the mounting frame 1 to the support leg 8, making the support leg 8 less prone to movement.

[0023] Furthermore, the top of the first mounting plate 9 and the second mounting plate 13 are both fixed with the first airbag 17, and the bottom of the first roller frame 11 and the second wheel frame 15 are both fixedly connected to the top of the first airbag 17.

[0024] The first airbag 17 can improve the buffering and shock absorption effect on the first roller frame 11 and the second wheel frame 15, thereby further improving the stability of the conveyor belt 4 during conveying.

[0025] Furthermore, the side block 19 surface buffer structure includes a second airbag 20, which is fixedly connected to the surface of the side block 19. A slider 21 is fixed to one end of the second airbag 20, and a rotating plate 22 is hinged to the top of the slider 21. The top of the rotating plate 22 is hinged to the bottom of the second wheel frame 15.

[0026] When the second wheel frame 15 moves downward due to vibration or impact, the rotating plate 22 will rotate, so that the slider 21 can move toward the side block 19. At this time, the air inside the second airbag 20 will be compressed to disperse the impact force on the second wheel frame 15. Then the second airbag 20 will reset itself, thereby playing a buffering and shock-absorbing effect, making the shock absorption effect on the second wheel frame 15 better.

[0027] Furthermore, two side plates 23 are fixed to the bottom of the slider 21, and a movable roller 24 is rotatably connected between the two side plates 23;

[0028] When the slider 21 is in motion, its bottom movable roller 24 can contact the surface of the second mounting plate 13, and the movable roller 24 can also rotate, which can reduce friction and make the slider 21 move more easily.

[0029] Furthermore, a telescopic flexible cover 26 is fixed to the top of the second mounting plate 13, and the top of the telescopic flexible cover 26 is fixedly connected to the bottom of the second wheel frame 15. A buffer sleeve 18 is fixed to the surface of both the first buffer roller 12 and the second buffer roller 16. The buffer sleeve 18 is made of rubber.

[0030] The telescopic flexible cover 26 can protect the spring shock absorber 14 under the second wheel frame 15, preventing external dust, materials and other impurities from entering the spring shock absorber 14 and preventing these substances from affecting the working performance of the spring or accelerating its wear. The buffer sleeve 18 can be set to allow it to be in direct contact with the belt, which can absorb and disperse the high-frequency micro vibrations transmitted from the conveyor belt 4, reducing these vibrations from directly acting on the first buffer roller 12 and the second buffer roller 16.

[0031] Furthermore, two guide plates 25 are fixed to the top of the mounting bracket 1, and the guide plates 25 are designed in a F-shape structure;

[0032] The design of the F-shaped guide plate 25 allows the material to more easily enter the surface of the conveyor belt 4 after falling onto the surface of the guide plate 25, thus improving the accuracy of the conveying system.

[0033] Working principle: When the drive motor 3 starts, it drives the conveyor belt 4 to move through the cooperation of the rotating roller 2, so that the conveyor belt 4 can transport materials. During the conveying process, the surface of the first buffer roller 12 can directly contact the bottom of the conveyor belt 4. The vibration generated by the conveyor belt 4 can be directly transmitted to the second damping block 10 through the first buffer roller 12, so that the first buffer roller 12 can absorb the vibration from the conveyor belt 4 itself. The first buffer roller 12 can also contact the top of the inner wall of the conveyor belt 4, so it can immediately absorb the vibration transmitted from the conveyor belt 4. At the same time, the spring damper 14 can... The vibration damping and buffering reduces the direct impact of vibrations on the mounting frame 1 or other structures. Furthermore, this design allows the spring damper 14 to mitigate the load from above when material falls onto the surface of the conveyor belt 4, causing significant impact or vibration. Simultaneously, the cooperation of the side block 19, the second airbag 20, the rotating plate 22, and the slider 21 further absorbs and disperses larger vibrational forces. This two-layer idler design achieves a multi-level vibration damping mechanism, significantly improving the vibration damping effect of the conveying system and ensuring the stability of material transport.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
