Description

Technical Field

[0001] The utility model relates to the technical field of transmission belts, in particular to an automatic transmission belt adjusting device. Background Art

[0002] Conveyor belts are material conveying equipment used in industries such as coal, mining, ports, electricity, metallurgy, and building materials. They have the characteristics of high tensile strength and long service life. They can be used for long-distance, large-span, large-volume, and high-speed material transportation. They are often used for the circulation and packaging of goods on assembly lines and in warehouses. However, conveyor belts may deviate during use. The goods carried on the conveyor belts may fall due to the deviation of the conveyor belts, and the sides of the deviated conveyor belts may also be greatly worn. Therefore, conveyor belts often use adjustment devices to correct the deviation of the conveyor belts to ensure the normal operation of the conveyor belts.

[0003] However, the existing conveyor belt adjustment devices mostly use limit correction. The long-term direct contact between the limit structure and the conveyor belt will also cause wear to the conveyor belt and reduce the service life of the conveyor belt. The existing conveyor belt adjustment devices are also not convenient for adjusting the degree of correction of the conveyor belt. Excessive correction can easily cause the conveyor belt to deviate to the other side, causing repeated correction. In order to solve the shortcomings of the existing technology, we propose an automatic conveyor belt adjustment device. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4As shown, a conveyor belt automatic adjustment device is provided, a bracket is provided at the bottom of the fixed frame 3, a first normally open contact 15 is provided at one end with a first wire, a driving motor 4 is electrically connected to the first wire, one end of the adjustment device body 1 is movably penetrated with one end of the push rod 6, a second normally open contact 19 is provided at one end with a second wire, a driving motor 4 is electrically connected to the second wire, a center point of a limit assembly 9 is horizontally aligned with the belt of the conveyor belt and a gap is provided, when the belt of the conveyor belt deviates, the deviated belt of the conveyor belt squeezes the limit assembly 9 on one side, and the lateral force applied by the belt pushes the limit assembly 9 to drive the push plate 8 to drive the first fixed block 11 to drive the insulating rod 12, the insulating rod 12 penetrates into the second fixed block 13 to abut the first normally open contact 15, the first normally open contact 15 is closed by the pressure of the insulating rod 12, and the first normally open contact 15 is closed. An electrical signal is transmitted to the drive motor 4 through the first wire, and the drive motor 4 starts to rotate forward. The output end of the drive motor 4 rotates to drive the screw 5 to rotate. The rotation of the screw 5 uses the thread to push the push rod 6 to push the elastic rubber column 7. The elastic rubber column 7 pushes the push plate 8. The push plate 8 pushes the limit assembly 9 to push the belt to resist the lateral force caused by the belt deviation. After the belt is corrected to its original position, the push rod 6 drives the insulating pressure plate 17 to abut the second normally open contact 19. The second normally open contact 19 is closed by the pressure of the insulating pressure plate 17. The insulating pressure plate 17 transmits an electrical signal to the drive motor 4 through the second wire, and the drive motor 4 starts to reverse. The output end of the drive motor 4 reverses to drive the screw 5 to reverse. The screw 5 reverses and uses the thread to drive the push rod 6 to retreat. The push rod 6 drives the elastic rubber column 7 to drive the push plate 8 to drive the limit assembly 9 to retreat to its original position.

[0023] The center point of the limit component 9 is horizontally aligned with the belt of the conveyor belt and a gap is provided. The limit component 9 does not contact the belt for a long time. The belt of the conveyor belt first contacts the limit sleeve 24 in the limit component 9. The continuously transmitted belt drives the limit sleeve 24 to drive the bearing 21 to rotate with the fixed shaft 22 as the axis. The bearing 21 reduces friction as much as possible and returns after adjustment to reduce the friction between the limit component 9 and the belt of the conveyor belt.

[0024] like Figure 2 and Figure 3As shown, a first fixing block 11 is detachably installed on the top of the push plate 8, and an insulating rod 12 is detachably installed on one end of the first fixing block 11, a second fixing block 13 is detachably installed on the top of the adjusting device body 1, and a first adjusting screw rod 14 is threadedly connected to one end of the second fixing block 13, and a first normally open contact 15 is rotatably connected to one end of the first adjusting screw rod 14, one end of the adjusting device body 1 is movably penetrated with one end of the push rod 6, and an insulating pressing plate 17 is detachably installed on one side of the push rod 6, a slider 18 is provided at one end of the adjusting device body 1, a slide groove is provided at the bottom of the inner wall of the slider 18, and the slider 18 is slidably connected inside the slide groove provided by the slider 18, a second normally open contact 19 is detachably installed on one side of the slider 18, and a second adjusting screw rod 20 is threadedly connected to one side of the slider 18. When the belt is wider, the gap between the belt and the bracket becomes smaller, and the limit assembly 9 is contacted earlier when it deviates. The first adjusting screw 14 is rotated to drive the first normally open contact 15 away from the insulating rod 12 in the second fixed block 13, and the insulating rod 12 is pushed to abut the first normally open contact 15. The stroke becomes longer to adapt to the wider belt, and then the second adjusting screw 20 is rotated to drive the slider 18 to drive the second normally open contact 19 to slide in the slide groove of the limit groove 16, and the push rod 6 drives the insulating pressure plate 17 to abut the second normally open contact 19. The stroke becomes shorter, thereby meeting the adjustment requirements of the wider belt. By adjusting the first adjusting screw 14 and the second adjusting screw 20, the adjustment stroke of the equipment when the belt deviates can be changed to meet the adjustment requirements of belts of different widths. The scope of application is wider and the practicality is stronger.

[0025] How it works

[0026] It should be noted that the utility model is an automatic adjustment device for a conveyor belt. When in use, firstly, the brackets arranged at the bottom of the two symmetrical fixed frames 3 are respectively installed on the symmetrical sides of the conveyor belt. The brackets arranged at the bottom of the fixed frame 3 drive the fixed frame 3 to drive the partition plate 2 to drive the adjustment device body 1. The adjustment device body 1 drives the movable rod 10 to drive the push plate 8 to drive the limit assembly 9. The center point of the limit assembly 9 is horizontally aligned with the belt of the conveyor belt and is provided with a gap. When the belt of the conveyor belt deviates, the deviated belt of the conveyor belt squeezes the limit assembly 9 on one side. The belt of the conveyor belt first contacts the limit sleeve 24 in the limit assembly 9. The continuously transmitted belt drives the limit sleeve 24 to drive the bearing 21 to rotate with the fixed shaft 22 as the axis and apply a lateral force. The lateral force applied by the belt pushes the limit sleeve 24 to drive the bearing 21. The bearing 21 drives the fixed shaft 22 to drive the mounting plate 23. The mounting plate 23 drives the push plate 8 to drive the first fixed block 11 to drive the insulating rod 12. The insulating rod 12 penetrates into the second fixed block 13 and abuts against the first normally open contact 15. , the first normally open contact 15 is closed by the pressure of the insulating rod 12, and the first normally open contact 15 transmits an electrical signal to the drive motor 4 through the first wire. The drive motor 4 starts to rotate forward, and the output end of the drive motor 4 rotates to drive the screw 5 to rotate. The screw 5 rotates and uses the thread to push the push rod 6 to push the elastic rubber column 7, and the elastic rubber column 7 pushes the push plate 8. The push plate 8 pushes the limit assembly 9 to push the belt to resist the lateral force caused by the belt deviation. After the belt is corrected to its original position, the push rod 6 drives the insulating pressure plate 17 to abut the second normally open contact 19. The second normally open contact 19 is closed by the pressure of the insulating pressure plate 17. The insulating pressure plate 17 transmits an electrical signal to the drive motor 4 through the second wire. The drive motor 4 starts to reverse, and the output end of the drive motor 4 reverses to drive the screw 5 to reverse. The screw 5 reverses and uses the thread to drive the push rod 6 to retreat. The push rod 6 drives the elastic rubber column 7 to drive the push plate 8 to drive the limit assembly 9 to retreat to its original position. The limit assembly 9 does not contact the belt for a long time and retreats after the adjustment is completed, thereby achieving the purpose of reducing friction and adjusting the belt.

[0027] When the belt is wider, the gap between the belt and the bracket becomes smaller, and the belt contacts the limit assembly 9 earlier when it deviates. The first adjusting screw rod 14 is rotated, and the first adjusting screw rod 14 rotates outward from the second fixed block 13. The first adjusting screw rod 14 drives the first normally open contact 15 to move away from the insulating rod 12 in the second fixed block 13. The time for the insulating rod 12 to squeeze and trigger the first normally open contact 15 is delayed, and the stroke of pushing the insulating rod 12 to abut against the first normally open contact 15 becomes longer to adapt to the wider belt. The second adjusting screw rod 20 is rotated, and the second adjusting screw rod 20 drives the slider 18 to drive the second normally open contact 19 to slide in the slide groove of the limit groove 16 by using the thread, and the second normally open contact 19 approaches the insulating pressure plate 17 in the initial position. The time for the insulating pressure plate 17 to squeeze and trigger the second normally open contact 19 is advanced, and the stroke of the push rod 6 driving the insulating pressure plate 17 to abut against the second normally open contact 19 becomes shorter, which is adapted to the wider belt, thereby meeting the adjustment requirements of the wider belt and realizing the adjustment requirements of belts of different widths.
