[0002] Conveyor chains are a common component in mechanical transmissions, particularly in automated production lines, logistics and conveying systems, food processing lines, industrial manufacturing, and other fields. They are primarily composed of a series of chain links, pins, rollers, and other components. Pins connect the chain links to form a closed loop, enabling the continuous conveyance of materials or movement of objects.

[0003] In order to ensure that existing conveyor chains can provide good mechanical properties and reduce their mechanical wear, they usually need to be lubricated after the chain has been used for a period of time. However, applying lubricants requires manual operation, which is time-consuming and labor-intensive, affecting efficiency. Moreover, loose chains will affect the conveying effect.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] Furthermore, it also includes an intermittent oil leakage component, which includes a top plate 11 fixedly arranged on the upper end of the inner side of the oil storage tank 5, and a floating plate 12 is vertically movably connected to the bottom of the top plate 11. Third through grooves 16 corresponding to the floating plate 12 are symmetrically arranged on both sides of the upper end of the oil storage tank 5, and the ends of the floating plate 12 pass through the third through grooves 16 and extend to the outside of the oil storage tank 5, and the floating plate 12 and the third through grooves 16 are slidably matched. The liquid level of the lubricating oil in the oil storage tank 5 is not higher than the bottom of the third through grooves 16. The floating plate 12 and the top plate 11 are in a state of contact with each other. A spring 18 is vertically arranged between them, a guide column 17 is vertically fixedly set on the top of the floating plate 12, and the upper end of the guide column 17 is movably guided by the top plate 11, and the spring 18 is sleeved on the outside of the guide column 17. The end of the first rotating shaft 8 extends to the outside of the lubrication box 4 and is fixedly provided with a driving arm 9 corresponding to the end of the floating plate 12, and an arc-shaped force-bearing plate 10 is fixedly provided at the end of the floating plate 12. A sealing plate 13 corresponding to the second through groove 15 and used to be plugged and sealed with the second through groove 15 is vertically arranged on the bottom of the floating plate 12.

[0026] It also includes a tensioning assembly, which includes a support 3 arranged on one side of the lower end of the chain body 1, and a second rotating shaft 19 is provided on the support 3. A connecting arm 20 is fixedly connected to the side wall of one end of the second rotating shaft 19, and the end of the connecting arm 20 away from the second rotating shaft 19 is rotatably connected to a tensioning wheel 21 engaged with the chain body 1, and the part where the chain body 1 is engaged with the tensioning wheel 21 is in a bent state.

[0027] In order to achieve buffering, the second rotating shaft 19 is rotatably connected to the support 3, and a torsion spring 22 is movably sleeved on one end of the second rotating shaft 19 away from the connecting arm 20, and one end of the torsion spring 22 is clamped on the side wall of the support 3, and the other end is clamped on the side wall of the connecting arm 20, so that the torsion spring 22 twists when the second rotating shaft 19 rotates.

[0028] It should be noted that the present invention is an automatic lubricating conveyor chain. When in use, the chain body 1 passes through the lubrication channel 6 and contacts the lubrication roller brush 7. When in operation, the lubrication roller brush 7 is driven to rotate, and the first rotating shaft 8 drives the driving arm 9 to rotate. The driving arm 9 intermittently contacts the force plate 10 and drives the floating plate 12 to rise through the force plate 10. When rising, the sealing plate 13 separates from the second through groove 15, and the lubricating oil leaks from the second through groove 15 to the lubrication roller brush 7. The lubrication roller brush 7 lubricates the chain body 1. When the force plate 10 separates from the driving arm 9, the floating plate 12 resets, and the sealing plate 13 seals the second through groove 15. This cycle continues. The driving arm 9 can also be set to a retractable structure, and it can be adjusted to contact the force plate 10 when lubrication is needed.

[0029] In addition, when the chain body 1 is running, the bottom is supported by the tensioning wheel 21, so that the chain body 1 is in a tensioned state, avoiding relaxation, and when the tensioning wheel 21 drives the second rotating shaft 19 to rotate through the connecting arm 20, it drives the torsion spring 22 to twist, thereby generating a reverse force, which can achieve a buffering effect.
