Description

Technical Field

[0001] This utility model belongs to the field of material transportation technology, specifically relating to a conveyor belt correction device and a belt conveyor. Background Technology

[0002] Belt conveyors are widely used in factory production, especially mining conveyors. Belt conveyors are used in the tobacco industry for the continuous transport of tobacco materials on production lines. They are suitable for the continuous transport of tobacco materials in tobacco processing lines, and can continuously transport loose materials such as tobacco stems, leaves, sheets, and shredded tobacco. They serve as auxiliary connecting equipment between various main machines. With the development of industrial automation and technology, belt conveyors, characterized by long distances, high belt speeds, and large transport capacities, have become the mainstream of belt conveyor equipment development. Due to installation accuracy deviations in the conveyor belt, adjusting rollers, and tension rollers, belt misalignment can occur during transport. Misalignment refers to the degree of non-alignment between the centerline of the conveyor belt and the perpendicular bisector of the adjusting roller during operation. The distance of this non-alignment is the misalignment amount. If the misalignment exceeds the allowable range of the equipment, the conveyor belt may collide with the frame, causing abnormal equipment operation and requiring significant time for conveyor belt adjustment, thus reducing the efficiency of tobacco material transport. Utility Model Content

The device uses a set of guide rollers to detect the deflection of the conveyor belt and adjusts the posture of the correction components when the conveyor belt deflects to counteract the deflection, thereby ensuring that the conveyor belt does not collide with the frame, so that the transportation equipment maintains a stable operating state and ensures the efficiency of tobacco material transportation.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: Firstly, a conveyor belt correction device is proposed, including two sets of stop wheels respectively disposed on both sides of the conveyor belt, a correction component disposed on one side of the conveyor belt, and an adjusting roller disposed on the conveyor frame; the correction component is connected to the stop wheel sets and the adjusting roller, the stop wheel sets abut against the conveyor belt to detect the deflection of the conveyor belt, and the correction component adjusts the angle of the adjusting roller to counteract the deflection of the conveyor belt when the conveyor belt deflects.

[0005] In this embodiment, the correction assembly includes a detection rod on which the guide wheel group is mounted, a first connecting rod and a second connecting rod disposed between the detection rod and the adjusting roller. The first end of the first connecting rod is rotatably connected to the detection rod, the second end of the first connecting rod is rotatably connected to the first end of the second connecting rod, the second end of the second connecting rod is connected to the adjusting roller, and the rotation center of the first connecting rod and the rotation center of the second connecting rod are fixed on the conveyor frame.

[0006] In this embodiment of the application, the correction assembly further includes reinforcing rods disposed on both sides of the first connecting rod, the first end of the reinforcing rod being rotatably connected to the conveyor frame, and the second end of the reinforcing rod being rotatably connected to the detection rod.

[0007] In this embodiment, the detection rod is a U-shaped rod, and the arrangement height of the detection rod is lower than the arrangement height of the adjusting roller.

[0008] In this embodiment of the application, the distance from the rotation center of the first link to the first end of the first link is greater than the distance from the rotation center of the first link to the second end of the first link and the length of the second link.

[0009] In this embodiment of the application, the width of the end of the second link closer to the first link is smaller than the width of the end of the second link farther from the first link.

[0010] In this embodiment of the application, the guide wheel group includes two guide wheels arranged sequentially along the conveyor belt conveying direction, and the two guide wheels are rotatably connected to the correction component.

[0011] In this embodiment of the application, the correction device further includes a reset component disposed between the correction component and the conveyor frame, the reset component being used to push the detection rod to the initial position.

[0012] In this embodiment, the reset assembly includes two springs, which are respectively disposed at both ends of the detection rod. The first end of the spring is connected to the conveyor frame, and the second end of the spring is connected to the detection rod.

[0013] Secondly, a belt conveyor is proposed, which includes the conveyor belt correction device described in the first aspect.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The present invention proposes a conveyor belt correction device and a belt conveyor, which uses a set of guide rollers to detect the deflection of the conveyor belt, and adjusts the posture of the correction component when the conveyor belt deflects to counteract the deflection, thereby ensuring that the conveyor belt does not collide with the frame, so that the transport equipment maintains a stable operating state and ensures the efficiency of tobacco material transport.

[0016] 2. The conveyor belt correction device and belt conveyor proposed in this utility model disperse the force on the first connecting rod by setting two reinforcing rods, avoid stress concentration, and extend the structural life of the correction component;

[0017] 3. The present invention proposes a conveyor belt correction device and a belt conveyor, wherein the detection rod is a U-shaped rod and the arrangement height of the detection rod is lower than the arrangement height of the adjusting roller, thereby ensuring that the detection rod does not come into contact with the material during the conveyor belt conveying process, thus improving the stability of the material conveyed by the conveyor belt;

[0018] 4. The conveyor belt correction device and belt conveyor proposed in this utility model have a width at the end of the second link closer to the first link that is smaller than the width at the end of the second link farther from the first link. This makes the side of the second link closer to the adjusting roller wider, thereby increasing the contact area between the second link and the adjusting roller, dispersing stress, and reducing wear. The side of the second link closer to the first link is narrower, which reduces the weight of the side of the second link closer to the first link, reduces inertia, and improves the flexibility when the first link drives the second link to move left and right.

[0019] 5. The present invention proposes a conveyor belt correction device and a belt conveyor. When the conveyor belt deviates, the conveyor belt will collide with the guide roller group, causing the entire detection rod to move to the left or right. At this time, one of the two springs is compressed and the other is stretched. When the conveyor belt returns to the normal position, the two springs push the detection rod back to the initial position under the action of the stretching or compressing force, so as to detect the deviance of the conveyor belt in the subsequent conveying process.

[0025] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0026] This utility model embodiment provides a conveyor belt correction device and a belt conveyor. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 It mainly includes a guide roller group 1, a correction component 2, and an adjusting roller 3.

[0027] In the first aspect, in the embodiments of this application, the conveyor belt correction device includes a set of guide rollers 1, a correction component 2, and an adjusting roller 3. The guide rollers 1 are arranged on both sides of the conveyor belt. When the conveyor belt is running, the guide rollers 1 abut against the sides of the conveyor belt. When the conveyor belt deviates, the conveyor belt pushes one side of the guide rollers 1 to cause displacement, thereby detecting the deviation of the conveyor belt. The adjusting roller 3 is arranged on the conveyor frame 5. The correction component 2 is connected to the guide rollers 1 and the adjusting roller 3. After the guide rollers 1 are displaced due to the deviation of the conveyor belt, the guide rollers 1 drive the correction component 2. The correction component 2 adjusts its own posture so that the center line of the conveyor belt coincides with the perpendicular bisector of the roller during operation, thereby counteracting the deviation of the conveyor belt. In this application, the guide rollers 1 are used to detect the deviation of the conveyor belt, and the posture of the correction component 2 is adjusted to counteract the deviation of the conveyor belt when the conveyor belt deviates, thereby ensuring that the conveyor belt does not collide with the frame, keeping the transport equipment in a stable operating state, and ensuring the efficiency of tobacco material transport.

[0028] In one possible implementation, the belt alignment assembly 2 includes a detection rod 21, a first connecting rod 22, and a second connecting rod 23. A guide wheel assembly 1 is arranged at both ends of the detection rod 21 and is rotatably connected to the detection rod 21. The first connecting rod 22 and the second connecting rod 23 are arranged between the guide wheel assembly 1 and the adjusting roller 3. The first end of the first connecting rod 22 is rotatably connected to the detection rod 21, and the second end of the first connecting rod 22 is rotatably connected to the first end of the second connecting rod 23. The second end of the second connecting rod 23 is connected to the adjusting roller 3. The rotation centers of the first connecting rod 22 and the second connecting rod 23 are fixed on the conveyor frame 5. When the conveyor belt deviates, it collides with the guide wheel assembly 1, causing the entire detection rod 21 to move to the left or right (left and right directions are...). Figure 2(In the left-right direction), the detection rod 21 will drive the first connecting rod 22 to rotate, the first connecting rod 22 will drive the second connecting rod 23 to rotate, and the rotation of the second connecting rod 23 will drive the adjusting roller 3 to rotate, so that the adjusting roller 3 drives the conveyor belt to return to the normal position. When the detection rod 21 moves to the left due to the deflection of the conveyor belt, the left end of the adjusting roller 3 will push the left side of the conveyor belt, thereby pushing the conveyor belt to the normal position. Similarly, when the detection rod 21 moves to the right due to the deflection of the conveyor belt, the right end of the adjusting roller 3 will push the right side of the conveyor belt, thereby pushing the conveyor belt to the normal position. By setting the first connecting rod 22 and the second connecting rod 23, this application ensures that when the conveyor belt deflects, the adjusting roller 3 can react correctly, thereby ensuring that the conveyor belt does not collide with the frame, so that the conveying equipment maintains a stable operating state and ensures the efficiency of tobacco material transportation.

[0029] In one possible implementation, the correction assembly 2 further includes reinforcing rods 24 disposed on both sides of the first connecting rod 22. The first end of the reinforcing rod 24 is rotatably connected to the conveyor frame 5, and the second end of the reinforcing rod 24 is rotatably connected to the detection rod 21. By setting two reinforcing rods 24, the force on the first connecting rod 22 is distributed, stress concentration is avoided, and the structural life of the correction assembly 2 is extended.

[0030] Furthermore, the detection rod 21 is a U-shaped rod, and the arrangement height of the detection rod 21 is lower than the arrangement height of the adjusting roller 3, thereby ensuring that the detection rod 21 does not come into contact with the material during the conveyor belt conveying process, thus improving the stability of the material conveying process.

[0031] Furthermore, the rotation center of the first link 22 (i.e. Figure 2 The distance from point A in the middle to the first end of the first link 22 is greater than the distance from the rotation center of the first link 22 to the second end of the first link 22, and the distance from the rotation center of the first link 22 to the first end of the first link 22 is greater than the length of the second link 23, where the rotation center of the second link 23 is... Figure 3 At point B, because the lever arm of the end of the first connecting rod 22 near the detection rod 21 is greater than the lever arm of the end of the first connecting rod 22 near the second connecting rod 23, the rotation angle of the end of the first connecting rod 22 near the detection rod 21 when the detection rod 21 rotates is less than the rotation angle of the end of the first connecting rod 22 near the second connecting rod 23. Therefore, when the guide wheel assembly 1 causes the detection rod 21 to make a small displacement, it can drive the first connecting rod 22 and the second connecting rod 23 to rotate, thereby adjusting the conveyor belt and improving the detection and adjustment accuracy of the conveyor belt.

[0032] Furthermore, the width of the end of the second link 23 closest to the first link 22 is smaller than the width of the end of the second link 23 furthest from the first link 22, making the side of the second link 23 closer to the adjusting roller 3 wider, thereby increasing the contact area between the second link 23 and the adjusting roller 3, dispersing stress, and reducing wear. The side of the second link 23 closer to the first link 22 is narrower, which reduces the weight of the side of the second link 23 closer to the first link 22, reduces inertia, and improves the flexibility of the first link 22 in moving the second link 23 left and right.

[0033] In one possible implementation, the guide wheel assembly 1 includes two guide wheels arranged sequentially along the conveyor belt conveying direction. The two guide wheels are rotatably connected to the detection rod 21. By setting two guide wheels arranged sequentially along the conveyor belt conveying direction, the contact area between the guide wheels and the conveyor belt is increased, thereby improving the detection accuracy of the conveyor belt. When the conveyor belt is not deflected, the conveyor belt will drive the guide wheels to rotate, thereby reducing the wear of the conveyor belt.

[0034] In one possible implementation, the conveyor belt correction device further includes a reset component 4, which is used to push the detection rod 21 back to its initial position to detect the conveyor belt deflection during subsequent conveying processes.

[0035] Specifically, the reset assembly 4 includes two springs, which are respectively disposed on both sides of the detection rod 21. The first end of the spring is connected to the conveyor frame 5, and the second end of the spring is connected to the detection rod 21. When the conveyor belt deflects, it collides with the guide roller assembly 1, causing the entire detection rod 21 to move to the left or right. At this time, one of the two springs is compressed and the other is stretched. When the conveyor belt returns to its normal position, the two springs, under the action of the stretching or compressing force, push the detection rod 21 back to its initial position to detect the deflection of the conveyor belt during subsequent conveying processes.

[0036] Secondly, a belt conveyor is proposed, which includes the conveyor belt correction device described in the first aspect.
