Description
Technical Field
[0001] This utility model relates to the field of belt conveyor technology; specifically, this utility model relates to a belt conveyor roller with self-cleaning function. Background Technology
[0002] With the rapid development of industrial technology, belt conveyors have been widely used in many enterprises such as ports, power plants, and mines due to their efficient and continuous material conveying capabilities. As one of the core components of belt conveyors, the performance of the rollers directly affects the operating efficiency and stability of the entire conveying system. Traditional belt conveyor rollers have gradually revealed many problems in practical applications. On the one hand, dust and damp materials often adhere to the surface of the conveyor belt during material transport. If these adhering substances are not cleaned in time, they will not only lead to accelerated wear and slippage of the conveyor belt, affecting conveying efficiency, but also increase equipment maintenance costs. On the other hand, when the conveyor belt deviates from its designated path, traditional rollers cannot automatically correct it, requiring frequent manual adjustments. This not only increases labor intensity but also poses a risk of equipment failure due to untimely adjustments. Furthermore, the impact force on the rollers when materials fall is relatively concentrated, easily causing severe localized wear and significantly shortening the roller's service life. Therefore, developing a new type of belt conveyor roller that can effectively solve the above problems is of significant practical importance. Utility Model Content

Detailed Implementation
[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0017] like Figures 1 to 5 As shown, a self-cleaning roller for a belt conveyor includes a cylinder 1 for driving the conveyor belt. Two spiral plates 2 are welded to the outer surface of the cylinder 1, which are symmetrically arranged on the left and right sides respectively. A mounting seat 3 is provided on both the left and right sides of the cylinder 1. The cylinder 1 is rotatably mounted between the two mounting seats 3 through bearings. A mounting frame 4 is provided on the side of the cylinder 1 facing the conveyor belt. The mounting seat 3 is fixedly mounted on the mounting frame 4. A cleaning component capable of cleaning the surface of the cylinder 1 is provided on the side of the mounting frame 4 away from the cylinder 1.
[0018] The main structure of the cylinder 1 used to drive the conveyor belt includes a cylinder skin 1.1, a bearing seat 1.2, and a bearing cover 1.3. The cylinder skin 1.1 and the bearing seat 1.2 are welded together to form the basic frame of the drum. Symmetrical spiral plates 2 are welded to its outer ring. The spiral plates 2 have two rotation directions: left-hand and right-hand. Finally, the shaft, bearing, and bearing cover 1.3 are installed into the bearing seat 1.2 in sequence to complete the assembly of the entire drum. After the conveyor belt is connected, the cylinder 1 is rotated and installed on the mounting base 3 through the shaft and bearing. The mounting base 3 is fixed on the mounting frame 4. By setting the spiral plates 2 on the outside of the drum, the spiral plates 2 can generate relative movement with the surface of the conveyor belt during the operation of the drum, effectively removing dust, wet materials and other debris adhering to the belt, avoiding the accumulation of impurities that may cause wear or slippage on the conveyor belt. At the same time, the cleaning components contact the surface of the cylinder 1 and the spiral plates 2 to clean the residual deposits between the cylinder 1 and the spiral plates 2, thereby realizing the self-cleaning function of the drum. In industries such as coal and chemicals that easily produce sticky materials, it can significantly reduce the frequency of equipment maintenance and improve production efficiency.
[0019] In this embodiment, the cleaning assembly includes a cleaning brush 5, a mounting plate 6, a fixing plate 7, and a connecting plate 8. The cleaning brush 5 is disposed on the top of the mounting plate 6, the fixing plate 7 is disposed on the bottom of the mounting plate 6, the mounting bracket 4 is provided with a crossbar 9 that is aligned with the axis of the cylinder 1, and the connecting plate 8 is rotatably disposed on the crossbar 9.
[0020] The cleaning brush 5 can better fit the surfaces of the cylinder 1 and the spiral plate 2, and has a better cleaning effect on the damp material that remains between the cylinder 1 and the spiral plate 2. The mounting plate 6 is used to install the cleaning brush 5, and the fixing plate 7 and the connecting plate 8 are rotatably set on the crossbar 9. The cleaning brush 5 can roll from bottom to top to clean the surfaces of the cylinder 1 and the spiral plate 2, resulting in higher cleaning efficiency.
[0021] In this embodiment, two rotating sleeves 10 are respectively symmetrically arranged on the left and right sides of the crossbar 9. The bottom of the connecting plate 8 is fixedly connected to the rotating sleeve 10. The end of the rotating sleeve 10 facing the mounting frame 4 and the shaft of the cylinder 1 on the same side are provided with a belt 11 for driving the rotating sleeve 10 to rotate.
[0022] The cleaning component is fixedly installed on the rotating sleeve 10, which is rotatably mounted on the crossbar 9. The rotating sleeve 10 and the rotating shaft of the cylinder 1 are connected by the belt 11. The part of the cylinder 1 being cleaned rotates in the opposite direction to the cleaning component. The cleaning component does not require an additional power system, which reduces structural costs and maintenance difficulty.
[0023] In this embodiment, multiple sets of cleaning components are provided and are evenly distributed along the circumferential direction of the rotating sleeve 10.
[0024] Multiple cleaning components are evenly distributed along the circumference of the rotating sleeve 10, providing comprehensive cleaning coverage and a stronger cleaning effect.
[0025] In this embodiment, the top surface of the fixing plate 7 is an arc surface, and the mounting plate 6 is a rubber block that can fit the top arc surface of the fixing plate 7. The cleaning assembly also includes an inverted triangle 12, a first connecting rod 13, and a limiting block 14. Two inverted triangles 12 are respectively symmetrically installed at the bottom of the mounting plate 6. One end of the first connecting rod 13 is rotatably installed at the bottom of the inverted triangle 12. The limiting block 14 is slidably sleeved between the two connecting plates 8 along the length direction of the connecting plate 8. The other end of the first connecting rod 13 is fixedly connected to the limiting block 14.
[0026] The middle part of the arc surface of the fixed plate 7 is always in contact with the mounting plate 6, and the mounting plate 6 will not rotate. The tripod can slide along the length of the connecting plate 8 under the action of the first connecting rod 13 and the limiting block 14. During the operation of the roller, the spiral plate 2 can generate relative movement with the surface of the conveyor belt, effectively removing dust, damp materials and other debris adhering to the belt. At the same time, after cleaning the adhering material between the cylinder 1 and the spiral plate 2, the cleaning brush 5 rotates upward and the limiting block 14 moves downward, which can drive the mounting plate 6 to fit against the arc surface of the top of the fixed plate 7. This causes the bristles of the cleaning brush 5 on the mounting plate 6 to split open to both sides, preventing the bristles of the cleaning brush 5 from sticking together due to cleaning the adhering material, which would affect the cleaning effect. At the same time, the adhering material on the bristles of the cleaning brush 5 is more easily removed from the bristles due to the splitting of the bristles.
[0027] In this embodiment, a fixing plate 15 is provided on both sides of the crossbar 9. A second connecting rod 16 is fixedly connected to the side of the fixing plate 15 facing the rotating sleeve 10. A first guide plate 17 is fixedly provided at the other end of the second connecting rod 16. The first guide plate 17 is sleeved on the rotating sleeve 10. A second guide plate 18 is provided on the side of the rotating sleeve 10 away from the fixing plate 15. Guide grooves 19 are opened on the opposite surfaces of the first guide plate 17 and the second guide plate 18. A third connecting rod 20 is provided on one side of the limiting block 14. One end of the third connecting rod 20 is located in the guide groove 19 of the first guide plate 17, and the other end passes through the first connecting rod 13 and extends into the guide groove 19 of the second guide plate 18.
[0028] The fixed plate 15 is located between the rotating sleeve 10 and the mounting bracket 4. The fixed plate 15 and the first guide plate 17 are fixedly connected by the second connecting plate 8. The belt 11 is located between the fixed plate 15 and the first guide plate 17. The second guide plate 18 and the crossbar 9 are fixedly connected. When the rotating sleeve 10 rotates, neither the first guide plate 17 nor the second guide plate 18 rotates. The rotating sleeve 10 is located between the first guide plate 17 and the second guide plate 18. The guide grooves 19 on the first guide plate 17 and the second guide plate 18 are the same. The two ends of the third connecting rod 20 are located in the guide grooves 19 on the first guide plate 17 and the second guide plate 18, respectively. Since the third connecting rod 20 passes through the first connecting rod 13, the third connecting rod can drive the inverted triangle frame 12 to move through the first connecting rod 13. When the cleaning component rotates to contact the surface of the cylinder 1, under the action of the guide groove 19, the third connecting rod 20 drives the limiting block 14 to move upward along the length direction of the connecting plate 8, and the inverted triangular frame 12 moves upward to support the mounting plate 6. At this time, the mounting plate 6 is in a rectangular state, and the cleaning brush 5 is in contact with the surface of the cylinder 1 and the spiral plate 2. When the rotating sleeve 10 continues to rotate, under the action of the guide groove 19, the third connecting rod 20 drives the limiting block 14 to move downward along the length direction of the connecting plate 8, so that the bottom surface of the mounting plate 6 is in contact with the arc surface of the top of the fixing plate 7. At this time, the mounting plate 6 is in an arc shape, and the bristles on the mounting plate 6 are blown apart to both sides due to the deformation of the mounting plate 6.
[0029] In this embodiment, a vertical plate 21 is provided on the side of the mounting frame 4 away from the roller, the cleaning component is located between the roller and the vertical plate 21, and a set of baffles 22 for cleaning the cleaning brush 5 is provided on the vertical plate 21.
[0030] After the cleaning brush 5 cleans the surface of the cylinder 1 and rotates to the other side, the bristles of the cleaning brush 5 remain in a frayed state. When it passes the vertical plate 21, the stop bar 22 straightens the bristles of the cleaning brush 5, further removing the adhering substances on the bristles and improving the cleaning effect of the bristles.
[0031] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
