Example
[0046] See Figures 1-3 As shown, a belt conveyor device is a mechanical device for material transfer, capable of adapting to the assembly needs of production lines with different spacing. The device includes a fixed support 1 as the main structure, with a groove on the fixed support 1, and a telescopic support 2 slidably mounted within the groove. A first belt roller 3 is securely mounted at one end of the fixed support 1, while a second belt roller 4 is mounted at the opposite end of the telescopic support 2. A first guide roller 5 and a second guide roller 6 are mounted at the lower end of the telescopic support 2; these guide rollers facilitate smooth transition of the belt during the transmission process.
[0047] The fixed support 1 is equipped with a motor-driven drive roller 8, a third guide roller 9, and a movable guide roller 7. Specifically, the fixed support 1 has a groove that limits the movement range of the movable guide roller 7. This design allows the movable guide roller 7 to move flexibly within a certain range to accommodate the forward and backward movement of the telescopic support 2. The belt 10 is sequentially wound around the first belt roller 3, the second belt roller 4, the first guide roller 5, the second guide roller 6, the movable guide roller 7, the drive roller 8, and the third guide roller 9, forming a complete transmission loop.
[0048] To enable flexible movement of the telescopic support 2, a transmission rack 11 is provided on the telescopic support 2, while an adjustment component 12 that meshes with the transmission rack 11 is provided on the fixed support 1. Driven by the adjustment component 12, the transmission rack 11 can drive the telescopic support 2 to move back and forth in the slide groove, thereby adjusting the distance between the first belt roller 3 and the second belt roller 4 to meet the assembly needs of different production lines.
[0049] In this embodiment, the adjustment component 12 is manually driven and specifically includes an adjustment shaft. Both ends of the adjustment shaft are securely fixed to the fixed bracket 1 via bearing seats, ensuring the stability and smoothness of the adjustment shaft during rotation. One end of the adjustment shaft extends to the outside of the fixed bracket 1 and is connected to a handwheel. By turning the handwheel, the adjustment shaft can be easily driven to rotate.
[0050] An adjusting gear is installed on the adjusting shaft, meshing with the transmission rack 11. When the adjusting shaft rotates, the adjusting gear rotates accordingly, thereby driving the transmission rack 11 to move, thus realizing the forward and backward movement of the telescopic bracket 2. This design makes the adjustment process both labor-saving and efficient.
[0051] Meanwhile, the motor is connected to the drive roller 8 via a coupling, providing power to the drive roller 8. The drive roller 8 is equipped with a connecting shaft adapted to the coupling, ensuring the accuracy and stability of power transmission.
[0052] In addition, the two ends of the central shaft of the movable guide roller 7 are slidably disposed in the grooves of the fixed bracket 1. The height of the grooves is precisely matched with the outer diameter of the central shaft of the movable guide roller 7, so that the movable guide roller 7 can move smoothly along the direction defined by the grooves, thereby effectively buffering the tension changes of the belt when the telescopic bracket 2 moves, and ensuring the effective transmission of the belt.
[0053] In this embodiment, a support leg 13 is provided on the telescopic bracket 2 on one side of the second belt roller 4. The support leg 13 is used to enhance the stability and support capacity of the telescopic bracket 2. The bottom of the support leg 13 is provided with a first universal wheel 14 and a first support foot 15 that can be adjusted in height. The first universal wheel 14 facilitates the movement and position adjustment of the telescopic bracket 2 when needed, while the first support foot 15 is used to provide stable support when the telescopic bracket 2 is fixed. The first support foot 15 is provided with a threaded first guide post, which passes through the reserved mounting hole on the support leg 13 and is locked with a nut, so that the height of the first support foot 15 can be easily adjusted to adapt to different ground conditions and usage requirements.
[0054] In this embodiment, a second slider 16 is provided in the slide groove, and a second linear slide rail 17 matching the second slider 16 is provided on the telescopic bracket 2. The cooperation between the second slider 16 and the second linear slide rail 17 provides a stable guiding effect for the movement of the telescopic bracket 2, ensuring that the telescopic bracket 2 maintains straightness and stability during movement.
[0055] In this embodiment, the fixed bracket 1 adopts a split design, specifically consisting of an upper bracket 101 and a lower bracket 102. This design not only facilitates manufacturing but also makes subsequent assembly and maintenance easier. A sliding assembly 103 is provided between the upper bracket 101 and the lower bracket 102. This sliding assembly 103 includes a first linear slide rail and a first slider. The first linear slide rail is fixed to the lower bracket 102, while the first slider is mounted on the upper bracket 101, allowing the upper bracket 101 to slide in a direction perpendicular to the moving direction of the telescopic bracket 2.
[0056] During use, when maintenance is required on the transmission components of the telescopic support 2, the lower support 102 can be kept stationary, and the component requiring maintenance can be easily exposed simply by sliding the upper support 101, greatly improving the convenience of maintenance. This design not only saves maintenance time but also reduces maintenance difficulty, making the entire belt conveyor device easier to manage and use.
[0057] Furthermore, the first slider is equipped with a limiting component to restrict its sliding position. This limiting component adopts an adjustable screw structure. The screw structure is adjusted by rotation; when loosened, the first slider can move, and when locked, the first slider will not move, thereby realizing the position adjustment between the upper bracket 101 and the lower bracket 102.
[0058] In this embodiment, the bottom of the fixed bracket 1 is provided with a second universal wheel 18 and a second support foot 19. This design ensures both the flexibility of the equipment when it needs to be moved and the stable support when the equipment is fixed. The height of the second support foot 19 can be adjusted according to actual usage needs to adapt to different ground conditions or equipment layouts. Specifically, the second support foot 19 has a threaded second guide post, which passes through a pre-drilled mounting hole on the fixed bracket 1 and is locked in place by a nut.
[0059] When adjusting the height of the second support leg, simply loosen the nut, adjust the second support leg 19 to the appropriate position, and then retighten the nut. This design makes the height adjustment of the fixed bracket 1 more flexible and convenient, while also enhancing the adaptability and stability of the equipment in different environments. In addition, the second caster wheel makes it easier and less strenuous to move or adjust the position of the equipment.
[0060] In summary, this belt conveyor device is designed to fully consider various practical needs, demonstrating significant advantages. Through the application of the movable guide roller 7, the belt receives effective cushioning when the telescopic support 2 moves back and forth. This design avoids belt slackness or tightness caused by changes in spacing, ensuring the stability and effectiveness of belt transmission.
[0061] Furthermore, thanks to the design of the sliding component 103, maintenance personnel can easily perform maintenance operations on the transmission components of the telescopic support 2 while the lower support 102 remains stationary, greatly improving maintenance convenience. Simultaneously, the entire device is easily transportable thanks to the omnidirectional wheels, adapting to the needs of different work sites. The telescopic support 2 is also equipped with support legs 13 and their omnidirectional wheels, further enhancing the stability of the telescopic movement and making the entire device more reliable and efficient during operation.
