[0021] Specifically, the protective device 7 includes a mounting member 71, which is fixedly connected to the surface of the servo motor body 8, a sliding rod 73 is slidably connected to the inner wall of the mounting member 71, and the surface of the sliding rod 73 is rotatably connected to a limiting wheel 75, an oiling box 74 is fixedly connected to the surface of the sliding rod 73, and two groups of oiling members 76 are rotatably connected to the inner wall of the oiling box 74, a transmission assembly 77 is arranged between the oiling member 76 and the limiting wheel 75, and an adjustment assembly 72 is arranged between the sliding rod 73 and the mounting member 71.
[0022] In this embodiment: during the transmission process of the equipment, the adjustment component 72 can drive the sliding rod 73 and the limiting wheel 75 to move in the mounting component 71, so that the limiting wheel 75 can press the chain body 6 downward to limit the position. When the limiting wheel 75 rotates, it can cooperate with the transmission component 77 to drive the oiling part 76 to rotate and apply oil, thereby adjusting the tightness of the chain body 6 and reducing the risk of falling off due to excessive looseness. At the same time, the chain can also be lubricated and protected.
[0023] Specifically, the mounting member 71 includes a sliding sleeve 711 . There are two sliding sleeves 711 . The two sliding sleeves 711 are fixedly connected to the surface of the servo motor body 8 . A connecting frame 712 is fixedly connected to the surface of the two sliding sleeves 711 .
[0024] Specifically, the adjustment assembly 72 includes a connecting block 722 , which is fixedly connected to the surfaces corresponding to the two slide bars 73 . The inner wall of the connecting frame 712 is rotatably connected to a screw rod 721 , and the screw rod 721 is threadedly connected to the inner wall of the connecting block 722 .
[0025] In this embodiment, when the adjusting assembly 72 is adjusting, the screw rod 721 is mainly rotated, and the screw rod 721 can drive the connecting block 722 and the sliding rod 73 to move in the sliding sleeve 711 in the mounting member 71, thereby controlling the limiting wheel 75 to adjust the tightness of the chain body 6.
[0026] Specifically, the oiling member 76 includes a rotating wheel 761, which is rotatably connected to the inner wall of the oiling box 74. Two sets of oiling brushes 762 are fixedly connected to the surface of the rotating wheel 761. When the rotating wheel 761 rotates, it can drive the oiling brush 762 to rotate. The oiling brush 762 can be stained with the lubricating oil in the oiling box 74 and then smeared on the chain body 6 to achieve lubrication, thereby reducing the inconvenience caused by manual smearing.
[0027] Specifically, the transmission assembly 77 includes a transmission wheel 1 771, which is fixedly connected to the surface of the rotating wheel 761, and a transmission wheel 2 772 is fixedly connected to the surface of the limiting wheel 75, and a transmission belt 773 is installed in the transmission wheel 1 771 and the transmission wheel 2 772.

When adjusting the tension and oiling, the lubricating oil can be placed in the oiling box 74, and the screw rod 721 is rotated. The screw rod 721 cooperates with the connecting plate to drive the sliding rod 73 to slide in the hollow sleeve, so that the limiting wheel 75 can press down the chain body 6 to adjust the tension. When the chain body 6 moves, the limiting wheel 75 can be driven to rotate. The limiting wheel 75 drives the transmission wheel two 772 to rotate. The transmission wheel two 772 drives the transmission wheel one 771 to rotate through the transmission belt 773. Since the size of the transmission wheel one 771 is larger than the size of the transmission wheel two 772, the transmission head one drives the rotating wheel 761 and the oiling brush 762 to rotate at a reduced speed. The oiling brush 762 can be stained with the lubricating oil in the oiling box 74, and then the chain body 6 is smeared to achieve lubrication, and the use can be completed.
