[0002] Belt conveyor is a kind of continuous conveying machine that is driven by friction, and the material is carried by conveying belt and is used as traction member to transmit power. Its working principle is that the conveying belt forms a closed loop structure after passing through the two end drums, and is tensioned by the tensioning device and has a certain tension. When the driving drum is rotated by the motor, the conveying belt is continuously operated by the friction between the driving drum and the conveying belt, so as to convey the material from the receiving point to the discharging point.
[0003] The existing belt conveyor often deviates (runs off) during operation. The deviation of the conveying belt may be affected by various factors, for example, the belt conveyor inevitably vibrates during operation, the faster the operation speed, the greater the vibration, and the greater the influence on the deviation of the conveying belt. Among them, the vibration caused by the radial runout of the carrier roller has the most significant influence on the deviation of the conveying belt. If the belt of the conveying belt deviates, it will cause the material to spill, causing resource waste, and the staff has to frequently adjust the belt of the conveying belt, affecting the work efficiency.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0026] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model discloses a conveyor belt anti-deviation device for a belt conveyor, comprising a base 1 with several threaded mounting holes. Four uprights 2, distributed at the four corners, are mounted on the base 1 by screws. A roller 3 is rotatably mounted between two adjacent uprights 2, and a conveyor belt 4 is mounted between two rollers 3. Both ends of the rollers 3 are fitted with annular parts 5, each with multiple extensions 6 located on one side of the conveyor belt 4. Two horizontal bars 7, spaced vertically apart, pass through the uprights 2, their ends fixedly connected to the extensions 6. Connecting frames 8 are provided on both sides of the conveyor belt 4, their ends fixedly connected to the horizontal bars 7 on the same side, and the connecting frames 8 on both sides are symmetrically distributed. Multiple equidistant ribs 9 are fixed to the connecting frames 8 facing the conveyor belt 4. A deviation correction mechanism is mounted on the base 1, connected to the connecting frames 8 on both sides, and used to adjust the position of the conveyor belt 4.
[0027] A motor is fixedly mounted on one of the uprights 2. The motor's output shaft is connected to and drives the roller 3 to rotate. The motor drives the conveyor belt 4 to rotate by rotating one side of the roller 3. Objects to be conveyed are placed on the conveyor belt 4, and the motor drives the conveyor belt 4 to move and convey the objects. Annular members 5 are provided on both sides of the conveyor belt 4 to limit its lateral movement, preventing it from deviating from the sides of the roller 3, thus achieving an anti-deviation function. An extension 6 is provided on the outer side of the annular member 5, which extends the anti-deviation range of the annular member 5 and can effectively prevent deviation of conveyor belts 4 of different thicknesses.
[0028] The correction mechanism includes two spaced-apart side plates 10, both fixedly connected to the base 1. Two spaced-apart guide rods 11 are fixedly installed between the two side plates 10, each passing through one of the side plates. A first lead screw 12 is rotatably mounted between the two side plates 10, passing through both side plates and threadedly connected to them. A first turntable 13 is rotatably mounted on one side plate 10, and the shaft of the first turntable 13 is fixedly connected to the first lead screw 12.
[0029] When the surface of the conveyor belt 4 is worn or due to other reasons, the objects on the conveyor belt 4 deviate from the preset movement path. Without replacing the conveyor belt 4 or adjusting its installation position, the first turntable 13 is rotated to drive the first lead screw 12 to rotate. This drives the connecting frames 8 on both sides to move synchronously. The annular parts 5, extensions 6, and ribs 9 on both sides also move synchronously. Thus, the conveyor belt 4 is pushed along the direction of the roller 3 by the pushing action of the annular parts 5, extensions 6, and ribs 9 on one side. The position of the conveyor belt 4 can be finely adjusted, thereby fine-tuning and correcting the movement path of the objects on the conveyor belt 4, so that the object's movement endpoint returns to the preset position. The device can conveniently fine-tune and correct the movement path of the objects to be conveyed, and the operation is convenient and efficient.
[0030] Because the conveyor belt 4 is soft, if a pushing force is applied from both ends of the conveyor belt 4, the two ends of the conveyor belt 4 may move while the middle section does not move, and the conveyor belt 4 will be bent. However, the ring part 5, the extension part 6 and the rib 9 apply force to the conveyor belt 4 at multiple points, and the movement of the conveyor belt 4 is smoother.
[0031] Meanwhile, when no correction work is required, the position of the conveyor belt 4 can be adjusted by pushing the conveyor belt 4 to move along the direction of the roller 3, thereby adjusting the conveying direction of the conveyor belt 4 according to external conveying needs, making the function of the correction mechanism more diversified.
[0032] The annular component 5, the extension 6, and the rib 9 are all polished on the side facing the conveyor belt 4. The friction between the annular component 5, the extension 6, and the rib 9 and the conveyor belt 4 is small, which reduces the wear generated during the movement of the conveyor belt 4 and effectively improves the service life of the conveyor belt 4.
[0033] The conveyor belt 4 has a carrier plate 14 at one end, on which three sets of equidistantly distributed photoelectric sensors 15 are mounted. The photoelectric sensors 15 on both sides face the sides of the conveyor belt 4, while the photoelectric sensor 15 in the middle faces the items on the conveyor belt 4. An adjustment mechanism is provided on the base 1, which is connected to the carrier plate 14 and used to adjust the horizontal position of the photoelectric sensors 15. The adjustment mechanism includes a slide rail 16 fixed to the base 1, with a cross-shaped groove inside. Two spaced-apart brackets 17 are fixed to the carrier plate 14, with their lower ends slidably disposed within the slide rail 16. A second lead screw 18 is rotatably mounted within the slide rail 16, passing through the lower ends of the two brackets 17 and threadedly connected to them. A second turntable 19 is rotatably mounted outside the slide rail 16, with its shaft fixedly connected to the second lead screw 18.
[0034] The position of the conveyor belt 4 is detected in real time by photoelectric sensors 15 on both sides, and the movement path of the items on the conveyor belt 4 is detected by a center photoelectric sensor 15. Both photoelectric sensors 15 are electrically connected to an external control system, and the photoelectric sensors 15 send the detected signals to the control system. The control system receives the signals from the photoelectric sensors 15 and processes and analyzes them. By comparing the preset position with the actual position, it determines whether the conveyor belt has deviated and the degree of deviation, and also determines whether the movement path of the items on the conveyor belt 4 has deviated and the degree of deviation, thus facilitating timely detection of the conveyor belt's operating status by staff.
[0035] When the installation position of the conveyor belt 4 changes, the second turntable 19 is rotated to drive the second lead screw 18 to rotate, which can drive the two supports 17, the carrier plate 14 and the photoelectric sensor 15 on the carrier plate 14 to move synchronously. The photoelectric sensor 15 moves along the direction of the slide 16 so that the position of the photoelectric sensor 15 matches the conveyor belt 4 and the items on the conveyor belt 4.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
