AI Technical Summary
Existing sandpaper production unwinding mechanisms are prone to deviation from their tracks during transportation, making it difficult to ensure the smooth transport of sandpaper.
The device employs a combination of a limiting device and a cleaning device. A motor drives a reciprocating screw to move the threaded sleeve and the limiting rod. Combined with a compression spring and an arc-shaped push plate, it ensures that the sandpaper is transported within a predetermined range. The brush bucket is driven by a pulley and gear transmission system to clean the surface.
This achieves stability and accuracy of sandpaper during transportation, prevents deviation, and improves cleaning efficiency and the load capacity of the device.
