Description

Technical Field

[0001] This utility model belongs to the technical field of chain conveyor lines, and in particular relates to a dual-drive synchronous device for long-distance chain conveyor lines. Background Technology

[0002] A chain conveyor line is a mechanized conveying device that uses a chain as the traction and load-bearing element, driven by a sprocket, to transport objects. It is one of the most widely used and fundamental conveying methods in industrial automation. A motor (usually a geared motor) provides power, driving the sprocket to rotate. The chain meshes with the sprocket, and when the chain is tensioned, it forms a closed loop. When the drive sprocket rotates, it drives the chain in a cyclical motion. The objects to be conveyed are placed directly on the chain or via a tooling plate (pallet) and transported as the chain moves. A search revealed a dual-drive synchronous structure for long-distance chain conveyors, disclosed in publication number CN216188487U. This structure includes a main drive unit and a PLC control unit. The long-distance chain conveyor has a main tensioning unit and a driven unit. The main tensioning unit includes a displacement sensor, the detection end of which is connected to the chain of the long-distance chain conveyor. The signal output of the displacement sensor is connected to the signal input of the PLC control unit. A second control signal output of the PLC control unit is connected to the control signal input of the driven unit. The driven unit has a reduction gear structure, which serves as the drive output of the driven unit and is connected to a second drive input of the long-distance chain conveyor, thus forming a synchronous control structure for the long-distance chain conveyor to maintain a constant chain speed. This structure features protection against workpiece stall and sag, chain compression, and drive stall / stop. While existing dual-drive synchronous devices for long-distance chain conveyors can meet usage requirements to some extent, they still have some shortcomings in practical applications. For example, this device drives the chain conveyor belt to rotate and transport goods through drivers on both sides. However, during use, the chain links are prone to loosening, which affects the connection between the driver and the chain, interfering with the normal transport of goods. In addition, the driver drives the chain to rotate through the transmission gear plate, and long-term friction will lead to increased friction, which not only affects the chain's rotation efficiency but also increases the burden on the driver.

[0003] To address this, we offer a dual-drive synchronous device for long-distance chain conveyor lines. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4 As shown, the dual-drive synchronous device for a long-distance chain conveyor line provided in this embodiment includes a main frame 1. A conveyor belt 2 is arranged inside the main frame 1. Chains are arranged on both sides of the inner circle of the conveyor belt 2. Support frames 5 are fixedly installed on both sides inside the main frame 1. Adjusting frames 8 are movably installed on the upper end of the support frames 5. The adjusting frames 8 are sleeved on both ends of the conveyor belt 2. Mounting rods 9 are fixedly installed inside the adjusting frames 8. Tensioning gears 10 that mesh with the chains are movably sleeved on both ends of the mounting rods 9. An adjusting structure is provided between the adjusting frame 8 and the support frame 5. The adjusting structure includes adjusting screw sleeves 6, which are rotatably installed inside the support frame 5. At the middle position of the part, the upper end of the adjusting screw sleeve 6 is movably inserted with the adjusting screw 7. The upper end of the adjusting screw 7 is fixedly connected to the adjusting frame 8. The adjusting screw 7 is threadedly connected to the adjusting screw sleeve 6. A dual-axis motor 3 is fixedly installed at the middle position of the lower end inside the main frame 1. Rotating rods 4 are rotatably installed on both sides inside the main frame 1. The rotating rods 4 are drivenly connected to the output end of the dual-axis motor 3. The other end of the rotating rods 4 is drivenly connected to the adjusting screw sleeve 6. Support rods 11 are movably inserted on both sides of the upper end of the support frame 5. A stop is installed at the lower end of the support rod 11. A support spring 12 connected to the stop and the support frame 5 is sleeved on the surface of the support rod 11. In this embodiment, when the conveyor belt 2 becomes loose, the dual-shaft motor 3 starts, driving the two rotating rods 4 to rotate synchronously. These two rotating rods 4, through the cooperation of precision bevel gears and reversing gears, transmit power to the adjusting sleeve 6, causing it to rotate as well. Guided by the thread, the adjusting screw 7 moves upward or downward as the adjusting sleeve 6 rotates. The movement of the adjusting screw 7 further drives the adjusting frame 8 to move up and down. During the up-and-down movement of the adjusting frame 8, the support rod 11 also moves up and down accordingly. At this time, the support spring 12 is moderately compressed or stretched by the stop block. Under the elastic action of the support spring 12, the support effect of the adjusting frame 8 is significantly strengthened. When the adjusting frame 8 moves up and down, the tensioning gear 10 effectively pulls the conveyor belt 2, thereby achieving precise adjustment of the tension of the conveyor belt 2. This series of actions not only effectively prevents the conveyor belt 2 from becoming loose, but also ensures that the conveyor belt 2 maintains a stable working state during the conveying process, avoiding the problem of affecting the overall conveying efficiency due to loosening.

[0020] like Figure 5 and Figure 6 As shown, the dual-drive synchronous device for long-distance chain conveyors provided in this embodiment has lubrication structures on both sides of the adjusting frame 8. The lubrication structures include friction sensors, which are located on both sides inside the adjusting frame 8 and on one side of the tensioning gear 10. Lubrication cylinders 13 are provided on both sides of the upper end of the adjusting frame 8. An outlet pipe 17 is installed at the lower end of the lubrication cylinder 13, located above the tensioning gear 10. An inlet pipe 16 is provided at the lower end of one side of the lubrication cylinder 13. A hydraulic telescopic rod 14 is installed at the upper end of the lubrication cylinder 13. The lower end of the hydraulic telescopic rod 14 is installed inside the lubrication cylinder 13 and has a pressure plate 15 installed thereon. The outlet pipe 17 and the inlet pipe 16 are located inside... Both are fixedly installed with sealing rings 18. The end of the outlet pipe 17 away from the lubrication cylinder 13 and the end of the inlet pipe 16 close to the lubrication cylinder 13 are both fixedly installed with sealing sleeves 20. One end of the sealing sleeve 20 is movably inserted with a movable rod 22. One end of the movable rod 22 is installed with a sealing block 19, which cooperates with the sealing ring 18. The other end of the movable rod 22 is movably inserted into the sealing sleeve 20 and is installed with a movable block 21. The surface of the movable rod 22 is fitted with a return spring 23 connected to the movable block 21. The movable rod 22, movable block 21, return spring 23 and sealing block 19 located inside the outlet pipe 17 and the inlet pipe 16 are in opposite states. In this embodiment, the design of the inlet pipe 16 allows it to be seamlessly connected to a pipe specifically used for storing lubricating fluid. When the pressure plate 15 is pushed to the upper position inside the lubrication cylinder 13 under the precise action of the hydraulic telescopic rod 14, the sealing block 19 inside the inlet pipe 16 is kept in a state of separation from the sealing ring 18 under the combined action of the movable rod 22, the movable block 21, and the return spring 23. This design ensures that the lubricating fluid can be continuously and effectively replenished inside the lubrication cylinder 13. At the same time, the sealing block 19 inside the outlet pipe 17 is also in a tight interlocking state with the sealing ring 18 under the synergistic action of the movable rod 22, the movable block 21, and the return spring 23, thereby effectively preventing unnecessary loss of lubricating fluid inside the lubrication cylinder 13. When the friction sensor keenly senses a significant increase in friction between the tension gear 10 and the chain, the hydraulic telescopic rod 14 responds quickly, driving the pressure plate 15 to move downward. At this time, the pressure plate 15 applies pressure to the lubricating fluid inside the lubrication cylinder 13, causing the sealing blocks 19 inside the inlet pipe 16 and outlet pipe 17 to be squeezed accordingly. The sealing blocks 19 inside the inlet pipe 16 and the sealing ring 18 are thus switched to a locked state, while the sealing blocks 19 inside the outlet pipe 17 are separated from the sealing ring 18. This change in state allows the lubricating fluid inside the lubrication cylinder 13 to be smoothly discharged through the outlet pipe 17, thereby lubricating the tension gear 10 in a timely and effective manner. After the lubrication process is completed, the pressure plate 15 returns to the upper position inside the lubrication cylinder 13 under the action of the hydraulic telescopic rod 14. At the same time, the sealing blocks 19 inside the inlet pipe 16 and outlet pipe 17 also return to their initial positions, ensuring that the entire system returns to normal working condition and is ready for the next lubrication operation. This design not only improves lubrication efficiency, but also ensures the stability and reliability of the system.
