Technical Field

[0001] This utility model belongs to the field of conveyors, and in particular relates to a belt conveyor alignment device. Background Technology

[0002] In industrial production, belt conveyors, as efficient and continuous material conveying equipment, are widely used in mining, ports, power, metallurgy, and other industries. However, in actual operation, conveyor belt misalignment (i.e., belt deviation) is one of the common malfunctions. Belt deviation can lead to material spillage, wear on the conveyor belt edges, and even serious consequences such as equipment jamming or belt tearing, forcing frequent production line shutdowns for adjustments. This not only increases labor maintenance costs but also significantly reduces production efficiency. Utility Model Content

Detailed Implementation

[0018] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a belt conveyor alignment device according to this utility model.

[0019] like Figures 1 to 4As shown, this utility model discloses a belt conveyor alignment device, including a bracket, a support portion mounted on the bracket for supporting the conveyor belt, and an adjustment device mounted on the bracket and cooperating with the support portion. The support portion supports the conveyor belt to ensure normal material transport on the conveyor belt, while the adjustment device, cooperating with the support portion, can adjust the position of the conveyor belt through the support portion to correct any deviation in the conveyor belt.

[0020] Specifically, the support unit includes a guide rail 3 mounted on a bracket, a slide rail 4 slidably mounted on the guide rail 3, and a roller assembly rotatably mounted on the slide rail 4 for supporting and limiting the conveyor belt. An adjusting frame 10 is also located on the slide rail 4. An adjusting device mounted on the bracket can adjust the position of the slide rail 4 via the adjusting frame 10. The roller assembly supports and limits the conveyor belt; when the adjusting device adjusts the slide rail 4 via the adjusting frame 10, the roller assembly on the slide rail 4 also drives the conveyor belt to adjust its position, thereby achieving the effect of correcting belt misalignment.

[0021] The roller assembly includes a connecting block 9 located on the top surface of the middle section of the slide rail 4. Second support blocks 8 are located at both ends of the top surface of the connecting block 9, and first support blocks 5 are located at both ends of the top surface of the slide rail 4. Support rollers 6 for supporting the conveyor belt are rotatably mounted between the first support block 5 and the second support block 8 on the same side via a rotating shaft. To prevent the conveyor belt from deviating beyond the support rollers 6, a flange 7 with a diameter larger than the diameter of the support roller 6 is provided at the outer end of each support roller 6, thereby limiting the conveyor belt. Figure 1 and Figure 2 As shown, the adjustment bracket 10 is located on both sides of the connecting block 9.

[0022] The aforementioned adjustment device includes a slider 11 and an electric push rod 15 mounted on a bracket. The slider 11 is slidably mounted on the bracket and is located below the guide rail 3. Two limiting plates 12 are provided on the top surface of the slider 11, and the adjustment frame 10 is located between the two limiting plates 12. The electric push rod 15 is connected to an external power source for power supply, and the telescopic end of the electric push rod 15 is connected to the slider 11. A sensing rod 21 is provided on the adjustment frame 10, and two sensing heads 20 are provided on the bracket. The sensing rod 21 is located between the two sensing heads 20, and both sensing heads 20 are connected to the electric push rod 15.

[0023] It should be noted that there is a gap between the adjusting frame 10 and the two limiting plates 12, i.e., between the adjusting frame 10 and the two limiting plates 12. Figure 1As shown, when the conveyor belt moves the adjusting frame 10 on the slide rail 4 to the right via the slide rail 4, the adjusting frame 10 also moves the connected sensing rod 21. When the sensing head 20 in the direction of the moving sensing rod 21 senses the sensing rod 21, the sensing head 20 sends a signal to the electric push rod 15. The electric push rod 15 pulls the slider 11 to the left, and the limiting plate 12 also pushes the slide rail 4 to the initial position via the adjusting frame 10. After moving to the initial position, the electric push rod 15 moves the slider 11 to the initial position. Similarly, when the slide rail 4 moves to the left and the sensing head 20 on the left side of the bracket senses the sensing rod 21, this sensing head 20 sends a signal to the electric push rod 15 and pushes the adjusting frame 10 to the initial position via the limiting plate 12 on the slider 11. After moving to the initial position, the electric push rod 15 moves the slider 11 to the initial position.

[0024] To prevent the slide rail 4 from moving when the conveyor belt is placed on the support roller 6 via the first support block 5 and the second support block 8, a second bolt 17 is threaded onto the side wall of the adjusting frame 10, and the second bolt 17 abuts against the side wall of the guide rail 3. Tightening the second bolt 17 fixes the position of the corresponding guide rail 3 of the adjusting frame 10 to prevent the slide rail 4 from moving. After the conveyor belt is placed, the second bolt 17 is rotated in the opposite direction to release the second bolt 17 from contact with the guide rail 3.

[0025] In this embodiment, both the guide rail 3 and the slide rail 4 are arc-shaped, and the two support rollers 6 are combined to form a V-shape. The V-shaped support rollers 6 can effectively prevent the conveyor belt from deviating from the support range of the two support rollers 6. Specifically, the bracket used to support the support part consists of a base 1 and vertical columns 2 set on the top surfaces of both ends of the base 1, and the guide rail 3 of the support part is set on the two columns 2. The slider 11 is slidably set on the base 1.

[0026] The limiting plate 12 and the slider 11 are slidably connected, and a groove is formed on the slider 11 for the limiting plate 12 to slide. End caps 13 are provided at both ends of the slider 11, and each end cap 13 is rotatably connected to a first bolt 14, which is rotatably connected to its corresponding limiting plate 12. By rotating the first bolt 14, the first bolt 14 will shift on the end cap 13, and the first bolt 14 will push the connected limiting plate 12 to move, thereby adjusting the distance between the limiting plate 12 and the adjusting frame 10, so that the conveyor belt has different ranges of offset distance. Of course, a C-shaped frame 18 is detachably mounted on the support via adjusting bolts 19, and the sensing head 20 is mounted on the C-shaped frame 18. The C-frame can be snapped onto the base 1, and the C-frame 18 can be directly installed on the base 1 using the adjusting bolt 19. After adjusting the position of the limiting plate 12, the adjusting bolt 19 can be removed. Then, the C-frame 18 can be moved to the appropriate position and fixed with the adjusting bolt 19. To ensure precise positioning of the limiting plate 12 and the C-frame 18 on the base 1, a scale 16 is provided on the side of the slider 11.

[0027] Instructions for use: Secure the adjusting frame 10 to the slide rail 4 using the second bolt 17. Then, place the conveyor belt on the support roller 6 and loosen the second bolt 17 after placement. When the conveyor belt deviates from its position during operation, the sensor head 20, sensing the direction of deviation, detects the sensor rod 21 and sends a signal to the electric push rod 15. The electric push rod 15 then performs a corresponding action, moving the slider 11. The slider 11 also moves via the limit plate 12, pushing the slide rail 4 connected to the adjusting frame 10 and the components on the slide rail 4 back to their initial position. Simultaneously, the conveyor belt placed on the support roller 6 will move to its initial position, achieving the purpose of adjusting the conveyor belt's deviation.
