Description

Technical Field

[0001] This utility model relates to the field of tubular belt conveyor technology, and in particular to an online torsion correction device for tubular belt conveyors. Background Technology

[0002] Tubular belt conveyors (tube belt conveyors) are widely used in the field of bulk material conveying due to their advantages such as closed conveying, spatial curved arrangement, and ability to increase conveying inclination angle. However, due to their inherent structural characteristics, the conveyor belt is prone to deviation and twisting during operation, leading to material leakage, belt wear, environmental pollution, and equipment downtime.

[0003] The causes of misalignment and torsion are complex, involving multiple aspects such as design, manufacturing, installation, and operating conditions, making it difficult to completely eliminate them at the source. Therefore, adjusting and correcting misalignment and torsion during the commissioning and operation phases has become a routine task to ensure the stable operation of the conveyor belt system.

[0004] Currently, the most common method for correcting misalignment is the use of inclined shims. This method requires stopping the machine, loosening the idler roller seat bolts, and then having an experienced worker add inclined shims between the idler roller seat and the window-frame mounting frame. The idler roller seat bolts are then tightened, creating a fixed inclination angle on the idler roller, thereby applying a restoring force to the conveyor belt. While this method is simple in structure and low in cost, it has the following significant drawbacks: 1. Operations must be stopped: This will disrupt normal production and cause economic losses; 2. Reliance on worker experience: The accuracy and effectiveness of the adjustment depend to a large extent on the worker's observation and judgment, resulting in unstable correction effects; 3. High workload and low efficiency: For long-distance conveyor belt machines, there are many adjustment points, and manual adjustment after stopping the machine is time-consuming and labor-intensive. 4. The effect cannot be verified in real time: After adjustment, the machine needs to be restarted to observe the effect. If the effect is not good, the machine needs to be stopped and adjusted again, which is a cumbersome process. Utility Model Content

[0024] The following combination Figures 1-6 The present invention will be further described in detail below. An embodiment of the present invention discloses an online torsion correction device for a conveyor belt machine.

[0025] Two sets of idler roller mechanisms are installed vertically on the window frame type mounting frame 1. The lower idler roller mechanism includes six idler roller groups 2 evenly arranged around the top, and the upper idler roller mechanism includes five idler roller groups 2 evenly arranged around the top and an online torsion correction device. The idler roller groups 2 can adopt a conventional idler roller structure. The online torsion correction device is arranged at the lower idler roller position of the tubular section. This position has a large contact force with the conveyor belt, a large torsion correction force, ample operating space, and is safe.

[0026] The online torsion correction device for the conveyor belt includes a base bracket 3, an idler frame 4, a roller 5, and a forward tilt adjustment mechanism 6. The base bracket 3 includes a U-shaped fixing plate 31, the middle of which is attached to the surface of the window frame type mounting frame 1 and has two mounting holes. The fixing plate 31 is fixed to the window frame type mounting frame 1 by bolts passing through the mounting holes, ensuring interchangeability with conventional idler roller sets 2. L-shaped support plates 32 are fixed to the left and right sides of the fixing plate 31, with the horizontal plate of the support plate 32 located above its vertical plate.

[0027] The roller frame 4 is located directly above the base bracket 3. The roller frame 4 includes a U-shaped roller plate 41 with the U-shaped opening facing upward. The roller 5 is rotatably installed inside the roller plate 41. A first ear plate 42 is fixedly connected to one side of the roller plate 41, and a second ear plate 43 is fixedly connected to the other side of the roller plate 41. The first ear plate 42 is fitted against the top surface of the horizontal plate of a support plate 32. A fixed shaft 44 is vertically inserted through the center of the first ear plate 42. The bottom end of the fixed shaft 44 is vertically fixed to the support plate 32. The first ear plate 42 is rotatably connected to the fixed shaft 44. The top end of the fixed shaft 44 is flattened to prevent the first ear plate 42 from vertically detaching from the fixed shaft 44.

[0028] Ear plate 43 is fitted onto the top surface of the horizontal plate of another support plate 32. Ear plate 43 has an elongated adjustment hole 431. The tilting adjustment mechanism 6 is installed on the support plate 32. The tilting adjustment mechanism 6 includes two connecting plates 61 arranged sequentially along the axis of the roller 5. The connecting plates 61 are fixed to the bottom surface of the horizontal plate of the support plate 32. A threaded rod 62 is rotatably passed between the two connecting plates 61. The axis of the threaded rod 62 is parallel to the axis of the roller 5. Two baffles 63 are fixed on the threaded rod 62. The two connecting plates 61 are located between the two baffles 63. The baffles 63 are close to the connecting plates 61, that is, the two baffles 63 restrict the axial movement of the threaded rod 62, and only allow the threaded rod 62 to rotate.

[0029] The horizontal plate of the support plate 32 for mounting the tilt adjustment mechanism 6 has a sliding hole 321 along the axis of the roller 5. There is an angle between the extension direction of the sliding hole 321 and the extension direction of the adjustment hole 431. A slider 64 is threadedly mounted on the threaded rod 62. The top of the slider 64 slides through the sliding hole 321. A pin 65 is vertically fixed to the top surface of the slider 64 and passes through the adjustment hole 431. A drive head 66 is fixed to the end of the threaded rod 62 away from the fixed plate 31. The drive head 66 can be a hexagonal head or a sleeve with an internal hexagonal hole. In this embodiment, the drive head 66 is a hexagonal head, which is used in conjunction with a wrench with a long handle (such as a cross wrench) to ensure that the operator works at a safe distance and avoids the risk of being caught in the entanglement.

[0030] The implementation principle of the online torsion correction device for the conveyor belt in this embodiment of the utility model is as follows: When the conveyor belt of the conveyor belt is found to be twisted, the operator does not need to stop the machine. He only needs to stand in a safe area, put the front end of the wrench on the drive head 66, and then rotate the wrench according to the twisting direction of the conveyor belt. The wrench drives the threaded rod 62 to rotate through the drive head 66. The threaded rod 62 drives the slider 64 to move the pin 65.

[0031] Since the slider 64 can only move within the sliding hole 321, the pin 65 applies a torque to the idler frame 4 when it moves within the adjusting hole 431, driving the idler frame 4 to rotate around the fixed shaft 44 as the center. This causes the rollers 5 on the idler frame 4 to rotate at the same angle, applying a reverse corrective torque to the conveyor belt running above. The operator can slowly adjust the belt while observing the twisting until the twist is corrected. Usually, multiple (e.g., 3-5) forward tilting adjustment mechanisms 6 are continuously adjusted within the twisting section to achieve the best twist correction effect.

[0032] The online torsion correction device for the tube conveyor of this utility model has the following significant advantages: 1. Online operation, no downtime required: This fundamentally avoids production interruptions and economic losses caused by error correction operations; 2. Precise adjustment and intuitive effect: The tilt angle can be adjusted steplessly and precisely through the screw mechanism. The operator can observe the torsion correction effect in real time while the equipment is running and make fine adjustments immediately. It requires little experience from the operator. 3. Safe and reliable: The use of a wrench and optimized operating space design ensures the safety of operators and avoids the risk of operators being involved. 4. Simple structure and low cost: The core only adds one adjustment mechanism, resulting in minimal cost increase, high performance improvement, and strong practicality during mass production; 5. Good compatibility: The installation dimensions are basically the same as those of the conventional idler roller group 2, which makes it easy to upgrade existing equipment and promote its application on newly built equipment.

[0033] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
