[0027] In this embodiment, the driving motor 3 is started, driving the active wheel 4 to rotate. The active wheel 4 is driven by the belt 6, so that the driven wheel 5 rotates. The rotation of the driven wheel 5 is transmitted to the conveyor belt assembly 2 through the belt 6, causing it to move. The collecting hopper 7 collects the abrasive and transports the abrasive step by step through multiple sets of transport plates 8. The guide box 24 installed on the top of the conveyor belt assembly 2 guides the abrasive to ensure that the abrasive is correctly transported to the required components. When the conveyor belt is overloaded, the anti-overload tube 9 feels additional pressure, and the anti-overload rod 10 is movable and extends into the anti-overload tube 9. When overload occurs, the overload force is greater than the pre-tightening force of the anti-overload spring 22, and the anti-overload rod 10 is forced to rotate. At this time, the moving block 14 moves in a directional manner in the moving groove 15, and the horizontal push frame 12 pushes the push block 13 to move. The pressure plate 21 is acted upon by the anti-overload spring 22, exerting pressure on the overload tube to prevent overload. Multiple sets of anti-overload springs 22 are connected to the force plate 23 to work together to prevent overload.

[0031] More specifically, the device starts, the collection hopper 7 collects the abrasive, the drive motor 3 starts, and the conveyor belt assembly 2 begins to move through the belt 6, and the abrasive is transported step by step. When the overload protection mechanism detects an overload, the motion block 14 and the push block 13 are activated to prevent overload. As needed, the lifting and adjustment mechanism is activated to adjust the height of the conveyor belt assembly 2. The guide box 24 guides the abrasive to ensure that it is properly transported to the required component. At the same time, the abrasive is recovered through the groove 25 and the recovery hopper 26. The support legs 27 of the base plate 1 provide stable support to prevent vibration and deviation during processing. After the abrasive is transported, the device stops, completing the loading process.

[0032] In summary, when the overall equipment is in use or running: when the operation of the step-by-step transport mechanism is required, the drive motor 3 is started, driving the active wheel 4 to rotate, the active wheel 4 is transmitted through the belt 6, so that the driven wheel 5 rotates, and the rotation of the driven wheel 5 is transmitted to the conveyor belt assembly 2 through the belt 6 to make it move, the collecting hopper 7 collects the abrasive and transports the abrasive step by step through multiple groups of transport plates 8, and the guide box 24 installed on the top of the conveyor belt assembly 2 guides the abrasive to ensure that the abrasive is correctly transported to the required components.

[0033] When the anti-overload mechanism is required to operate, when the conveyor belt is overloaded, the anti-overload tube 9 feels additional pressure, and the anti-overload rod 10 is movable and extends into the anti-overload tube 9. When overload occurs, the overload force is greater than the preload force of the anti-overload spring 22, and the anti-overload rod 10 is forced to rotate. At this time, the moving block 14 moves in a directional manner in the moving groove 15, and the horizontal push frame 12 pushes the push block 13 to move. The pressure plate 21 is acted upon by the anti-overload spring 22, which applies pressure to the overload tube to prevent overload.

[0034] When the lifting and adjusting mechanism needs to be operated, the telescopic cylinder 16 is started, and the bottom rotating rod 18 of the telescopic cylinder 16 moves relatively. The other end of the telescopic cylinder 16 is movably connected to the connecting frame 19, and the connecting frame 19 is transmitted to the conveyor belt assembly 2 to realize the lifting and lowering adjustment of the conveyor belt assembly 2.

[0035] The device starts up, the collection hopper 7 collects the abrasive, the drive motor 3 starts, and the conveyor belt assembly 2 begins to move through the belt 6, and the abrasive is transported step by step. When the overload protection mechanism detects an overload, the motion block 14 and the push block 13 are activated to prevent overload. As needed, the lifting and adjustment mechanism is activated to adjust the height of the conveyor belt assembly 2. The guide box 24 guides the abrasive to ensure that it is properly transported to the required component. At the same time, the abrasive is recovered through the groove 25 and the recovery hopper 26. The support legs 27 of the base plate 1 provide stable support to prevent vibration and deviation during processing. After the abrasive is transported, the device stops, and the loading process is completed.
