Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to an anti-deviation belt conveyor. Background Art

[0002] Belt conveyors have strong conveying capacity, long conveying distance, simple structure, easy maintenance, and can easily implement programmed control and automatic operation. The continuous or intermittent movement of the conveyor belt is used to convey items under 100KG or powdery or granular items. It runs at high speed, smoothly, with low noise, and can be transported up and down slopes.

[0003] For example, in an anti-deviation belt conveyor with the authorization announcement number "CN211109381U", the strip grooves of the bearing plate and the annular grooves on the active roller and the driven roller together limit the deviation of the convex strips in the direction perpendicular to the conveyor belt, reducing the probability of the conveyor belt deviating; after placing the material on the conveyor belt, the upper layer of the conveyor belt can be pressed against the bearing plate, so that the convex strips are not easy to fall out of the strip grooves, and the conveyor belt is less likely to deviate. However, the anti-deviation belt conveyor requires the operator to manually adjust the position of the driven shaft by adjusting the positioning bolts. Since the positioning bolts need to be turned many times when adjusting the positioning bolts manually, it takes a long time, thereby reducing work efficiency. At the same time, the anti-deviation belt conveyor has no early warning function. When the belt deviates, if the operator fails to find it in time, it is easy to cause the belt to be directly wrapped around the active shaft and the driven shaft, causing damage to the belt, thereby increasing work costs. Utility Model Content

[0027] Working principle:

[0028] When adjusting the anti-deviation belt conveyor:

[0029] Moving plate adjustment process:

[0030] First, adjust the distance between the moving plates 10 on both sides according to the width of the conveyor belt, turn the bolt 906 counterclockwise, and then start the power supply of the second motor 902 on the left. The output shaft of the second motor 902 rotates counterclockwise to drive the gear 903 to rotate, thereby driving the rack 904 to slide along the surface of the roller 905, so that the rack 904 slides to the right along the through hole processed on the first shell 901, and the rack 904 moves to the right to drive the moving plate 10 to move to the right. When the signal transmitter 7 and the signal receiver 5 move to the vicinity of the belt 11, turn off the power supply of the second motor 902 on the left, turn the bolt 906 clockwise to make the end of the bolt 906 press against the surface of the rack 904, and similarly adjust the position of the moving plate 10 on the right to move the moving plate 10 on the right to the vicinity of the belt 11.

[0031] Slide roller adjustment process:

[0032] Start the power supply of the third motor 302, the output shaft of the third motor 302 rotates to drive the rotating rod 303 to rotate, thereby driving the transmission rod 304 to move back and forth, the movement of the transmission rod 304 drives the slider 305 to slide back and forth along the slide groove processed on the fixed plate 306, and at the same time drives the connecting rod 307 to move, and the movement of the connecting rod 307 drives the moving frame 308 to slide back and forth along the through hole processed on the second shell 301, when the rotating rod 303 rotates 90 degrees clockwise, the moving frame 308 moves to the maximum distance, and the moving frame 308 moves downward, driving the sliding roller 4 to move downward.

[0033] Preventing belt deviation process:

[0034] When the belt 11 deviates, the belt 11 blocks the signal receiver 5 from receiving the signal, and the signal transmitter 7 makes the buzzer 5 sound to remind the staff that the belt 11 deviates. The operator can turn off the power supply of the first motor 2 in time to prevent the belt 11 from being damaged, thereby reducing the working cost, and then start the power supply of the third motor 302, and the moving frame 308 moves downward to drive the sliding roller 4 to move downward. When the surface of the sliding roller 4 is tightly fitted with the surface of the belt 11, the surface of the belt 11 is tightly fitted with the surfaces of the two rotating rollers 6, so that the tightness of the belt 11 can be quickly adjusted to prevent the belt from deviating, thereby improving the working efficiency.
