Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts production, and particularly to a belt conveying device. Background Art

[0002] With the rapid development of automated and flexible production in modern manufacturing, the production line processes are continuously iteratively optimized, and higher requirements are put forward for the adaptability, flexibility, and efficiency of equipment in the material conveying link. As the core equipment for material transfer in the production line, belt conveyors are widely used in multiple scenarios such as assembly, processing, and warehousing, and their performance directly affects the overall operation efficiency of the production line, the stability of product conveying, and the manual labor intensity. To adapt to the production requirements of multiple processes, multiple specifications, and multiple beats, there is an urgent need in the industry for conveying equipment with multi-functional integration, flexible adjustment, safety, and reliability, so as to break through the limitations of traditional conveying modes and continuously improve the automation level and production efficiency of the production line.

[0003] In the current industrial production scenarios, conventional belt conveyors have become basic conveying equipment, but the existing equipment generally has a single function and insufficient adjustment ability, making it difficult to meet the requirements of flexible production. Most traditional conveying devices use external motors for driving, with a loose structure and large space occupation, and can only achieve one-way fixed-speed conveying, without integrating functions such as speed regulation, commutation, and limit protection; the belt length is mostly fixed and non-adjustable, unable to adapt to different station spacings and working spaces; there is a lack of effective limit detection mechanisms at the conveying end, easily resulting in problems such as workpiece overtravel and dropping, and the external drive has a large running noise and poor heat dissipation effect, and is prone to failures during long-term continuous operation, with weak environmental adaptability.

[0004] The technical defects of existing belt conveyors directly lead to many problems in production applications. For example, one-way conveying and fixed speed cannot match the requirements of multi-process commutation and variable-beat operations, reducing the adaptability and transfer efficiency of the production line; the fixed-length design makes the equipment have poor versatility, and customized equipment is required for different stations, increasing the input cost; the external drive structure is complex and inconvenient to maintain, and the noise and heat dissipation problems affect the working environment and the service life of the equipment. These problems greatly increase the intensity of manual handling and auxiliary operations, restricting the improvement of the flexibility and automation level of the production line. Therefore, it is of great practical significance to design a multi-functional belt conveyor with forward and reverse rotation, adjustable speed, and retractable function. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a belt conveying device to fundamentally solve the problem that the equipment structure of the current belt conveying device is fixed and the function is single, and it cannot be adaptively adjusted according to different practical scenarios.

[0006] According to an embodiment of the present invention, a belt conveyor includes a first support assembly, a second support assembly located on one side of the first support assembly and providing parallel support, and a belt assembly movably disposed on the first support assembly and the second support assembly; The belt assembly includes a drive roller fixedly mounted on the first support assembly, a driven roller movably mounted on the second support assembly, a split roller assembly disposed between the drive roller and the driven roller, and a transmission belt wound around the drive roller, the driven roller, and the split roller assembly, wherein the split roller assembly is used to tension the conveyor belt; The second support assembly includes an adjustment component movably connected to the driven roller; The driven roller is driven to slide closer to or further away from the driving roller by the adjustment component, so as to adjust the distance between the driving roller and the driven roller, and the tension of the slack conveyor belt in the middle section is implemented by the roller splitting component.

[0007] Furthermore, the roller assembly includes a set of linked rollers mounted on the second support assembly and disposed near the driven roller, a second set of linked rollers disposed on the side of the linked rollers away from the driven roller, and a support roller mounted on the first support assembly and disposed near the driving roller for supporting the conveyor belt.

[0008] Furthermore, the linkage roller group and the second linkage roller group have the same structure. The linkage roller group includes a sliding shaft that slides on the second support assembly, a take-up roller sleeved on the circumference of the sliding shaft, and elastic parts disposed at both ends of the sliding shaft and perpendicular to its axial direction.

[0009] Furthermore, the second support assembly also includes a fixed frame for accommodating the linkage roller group, a side frame disposed on the top of the fixed frame for accommodating the second linkage roller group and the adjustment component respectively, and a first slide rail disposed in the middle of the side frame.

[0010] Furthermore, the side frame is provided with two second slide rails located on both sides of the first slide rail, and the adjustment component slides along the trajectory of the second slide rails and is positioned on the first slide rail.

[0011] Furthermore, the adjustment assembly includes a sliding wheel clamped on both sides of the first slide rail and embedded in the second slide rail, sliding along a track; a slide table axially fixed to the sliding wheel; and an adjustment part movably disposed on the slide table for driving the sliding wheel to tension.

[0012] Furthermore, the sliding wheel is fixedly connected to a sliding plate on the side away from the sliding table, and the driven roller is movably mounted on the sliding plate.

[0013] Furthermore, the belt conveyor also includes a positioning monitoring component located near the drive roller, and a protective frame for covering the outer surface of the side frame.

[0022] Please see Figures 1 to 5 The diagram shows a belt conveyor device according to a first embodiment of the present invention, including a first support assembly 1, a second support assembly 2 located on one side of the first support assembly 1 and parallel to it, and a belt assembly movably disposed on the first support assembly 1 and the second support assembly 2. The belt assembly includes a drive roller 4 fixedly disposed on the first support assembly 1, a driven roller 5 movably disposed on the second support assembly 2, a roller divider assembly disposed between the drive roller 4 and the driven roller 5, and a transmission belt 6 wound around the drive roller 4, the driven roller 5 and the roller divider assembly. The roller divider assembly is used to tension the transmission belt 6. The second support assembly 2 includes an adjustment assembly movably connected to the driven roller 5. The adjustment assembly drives the driven roller 5 to slide towards or away from the drive roller 4 to adjust the distance between the drive roller 4 and the driven roller 5, and the roller divider assembly is used to tension the slack section of the transmission belt 6.

[0023] Furthermore, the roller distribution assembly includes a linkage roller group 22 mounted on the second support assembly 2 and disposed near the driven roller 5, a second linkage roller group 210 disposed on the side of the linkage roller group 22 away from the driven roller 5, and a support roller 7 mounted on the first support assembly 1 and disposed near the driving roller 4 for supporting the conveyor belt 6. The linkage roller group 22 and the second linkage roller group 210 have the same structure. The linkage roller group 22 includes a sliding shaft 222 sliding on the second support assembly 2, a take-up roller 221 sleeved on the circumference of the sliding shaft 222, and a support roller 7 disposed on the second support assembly 222. The sliding shaft 222 has elastic portions 223 at both ends and perpendicular to its axial direction. The second support assembly 2 also includes a fixed frame 21 for accommodating the linkage roller group 22, a side frame 23 disposed on the top of the fixed frame 21 for accommodating the second linkage roller group 210 and the adjustment component respectively, and a first slide rail 24 disposed in the middle of the side frame 23. The side frame 23 has two second slide rails 28 located on both sides of the first slide rail 24. The adjustment component slides along the trajectory of the second slide rails 28 and is positioned on the first slide rail 24. The adjustment component includes components clamped to the first slide rail 24. The sliding wheels 27, which are embedded in the second slide rail 28 on both sides and slide along the track, are connected to a slide table 25 which is axially fixed to the sliding wheels 27. An adjustment part 26, which is movably mounted on the slide table 25 for driving the sliding wheels 29 to be tensioned, is also provided. In some optional embodiments of the present invention, the sliding wheels 29 can also be connected to the drive gear on the adjustment part 26 via axially arranged transmission gears. During operation, the adjustment part 26 can drive the sliding wheels 29 to slide along the track of the first slide rail 24 to improve the accuracy of the adjustment process. The sliding wheels 27 are fixedly connected to the sliding wheel on the side away from the slide table 25. Plate 29, driven roller 5 is movably mounted on sliding plate 29, belt conveyor also includes a position monitoring component set near the side of drive roller 4, and a protective frame 3 for the outer surface of the packing side frame 23. It should be noted that the protective frame 3 is provided with a through groove corresponding to the first support assembly 1 and the second support assembly 2, such as the second slide rail 28, to ensure that sliding space is provided. The position monitoring component includes a support frame 8 extending outward from the top of the first support assembly 1, and a sensor 9 embedded in the support frame 8 with the monitoring end facing upward and parallel to the conveyor belt 6.

[0024] It should be noted that in some optional embodiments of the present invention, at least one controller is provided at any convenient location for operation by the operator on the belt conveyor. The controller can be an MCU (Microcontroller Unit) chip to realize the overall control of the belt conveyor through the MCU chip. The controller and the belt conveyor are electrically connected, and the electrical connection includes wired connection and wireless connection. The wireless connection method includes, but is not limited to, Bluetooth connection, WiFi, IF radio frequency, and Zigbee. The wired connection method includes, but is not limited to, the network communication line connecting the belt conveyor and the controller.

[0025] In practical implementation, firstly, the operator can adjust the belt conveyor's spacing and drive direction based on the usage scenario, such as the conveying distance and direction. Regarding the drive direction adjustment, the operator can adjust the drive direction of the axial drive motor on the drive roller 4 using the controller. It should be noted that the drive motor on the drive roller 4 can be a bidirectional servo motor, as understood by those skilled in the art. Next, the conveying distance of the belt conveyor is adjusted. Specifically, the operator can adjust the conveying distance according to the usage scenario by shaking the adjusting unit 26 to rotate it axially, thereby driving the drive gear on its axial direction and causing the transmission gear on the sliding wheel 27 to rotate. It should be noted that the drive gear is located between and meshes with the two transmission gears, and then the drive gear sequentially drives the transmission gears on the upper and lower sides. The sliding wheel 27 rotates, causing it to slide against the surface of the first slide rail 24. The two sliding wheels 27 are located on the upper and lower sides of the first slide rail 24 respectively, forming a clamping effect, greatly ensuring stability during the adjustment process. Furthermore, since the sliding wheel 27 is also embedded in the second slide rail 28, the stability of the sliding process is further ensured, preventing displacement and deformation caused by uneven force on the upper and lower sides of the slide rail during adjustment. Next, the sliding wheel 27 drives the sliding plate 29 connected to it on the side away from the slide table 25 to slide laterally along the trajectory of the second slide rail 28. The sliding plate 29 then drives the driven roller 5 to slide laterally, ultimately achieving the purpose of adjusting the distance between the driven roller 5 and the driving roller 4. The adjustment and adaptation distance is 3-5m. To ensure the structural stability of the driven roller 5 after adjustment, in some optional embodiments, a slot (such as a groove) can be provided on the adjustment part 26 to engage with the first slide rail 24. Figure 2 The elastic fastener (as shown) can be fixed in place by pressing the elastic fastener into the slot of the first slide rail 24 after adjustment. In addition, in some optional embodiments of the present invention, based on the lateral sliding adjustment of the driven roller 5, the adjustment part 26 can be replaced with a servo motor with bidirectional output. The motor drives the sliding wheel 27 to slide along the trajectory of the first slide rail 24, realizing electronic control and facilitating operation by the operator.

[0026] Furthermore, during the spacing adjustment process between the driving roller 4 and the driven roller 5, the conveyor belt 6 may experience slackness or tautness. To address this, this application includes an adaptive adjustment component for spreading the conveyor belt 6, comprising a linkage roller group 22 and a second linkage roller group 210. It should be noted that the second support assembly 2 has oblong holes (e.g., at the mounting points of the linkage roller group 22 and the second linkage roller group 210) on its mounting surface. Figure 2 (As shown) to provide an adaptive adjustment range, it can be understood that the linkage roller group 22 and the second linkage roller group 210 can be adjusted according to the distance between the driving roller 4 and the driven roller 5, achieving adaptive position adjustment within the oblong hole, specifically, as... Figure 4 and Figure 5 As shown, the excess conveyor belt 6 at the bottom is tensioned by the linkage roller group 22 and the second linkage roller group 210. When the drive roller 4 and the driven roller 5 contract, there will be excess slack in the conveyor belt 6. The drive roller 4 and the driven roller 5, which are no longer tensioned, will distribute the rebound force through the elastic part 223, so that the linkage roller group 22 and the second linkage roller group 210 slide in their corresponding waist-shaped holes and stop after reaching the corresponding position to achieve adaptive balance, so as to ensure the smooth opening of the conveyor belt 6.

[0027] In some optional embodiments of the present invention, in order to further improve the smooth opening of the conveyor belt 6 during use, a tooth can be provided in the waist-shaped hole adapted to the linkage roller group 22 and the second linkage roller group 210, and an elastic buckle adapted to the tooth can be provided at the corresponding sliding shaft 222. The tooth can be adjusted to move closer to or further away from the elastic buckle to achieve the effect of disengaging from or engaging with the elastic buckle. This effect can be activated when the driving roller 4 and the driven roller 5 are adjusted, so that the tooth engages with the elastic buckle and achieves locking at different adjustment positions, improving the stability of the linkage roller group 22 and the second linkage roller group 210 after adjustment. When the conveying distance needs to be readjusted in the future, the tooth can be relatively disengaged from the elastic buckle, so that the linkage roller group 22 and the second linkage roller group 210 are centered under the influence of the elastic part 223, so that the tooth can be adjusted to engage with the elastic buckle in the subsequent adjustment.

[0028] Finally, when using a belt conveyor, in order to ensure the quality of the conveyed items and prevent the items from falling, the sensor 9 can also be used to perform material identification at the discharge end. In some optional embodiments, the sensor 9 includes, but is not limited to, an infrared sensor, a pressure sensor, and a position sensor. After detecting that the conveyed item has arrived at the discharge end, it can send a trigger information to the controller, which will then control the drive roller 4 to stop conveying and wait for manual intervention from the operator. After cleaning the items at the discharge end, the drive roller 4 will restart the conveying, ensuring the quality of the conveyed items and avoiding the trouble of repeated manual operation and line stoppage.

[0029] In summary, the belt conveyor device in the above embodiments of the present invention drives the driven roller 5 to slide closer to or further away from the driving roller 4 through the adjusting component, so as to adjust the distance between the driving roller 4 and the driven roller 5, and tensions the slack conveyor belt 6 in the middle section through the roller splitting component, thereby improving the flexibility of the belt conveyor device. It is suitable for adaptive adjustment of the conveyor distance of different production lines, and solves the problem that the current belt conveyor device has a fixed structure and single function, and cannot be adaptively adjusted according to different practical scenarios.
