AI Technical Summary
In existing corrugated cardboard production feeding devices, when the material roll is fixed by the expansion roller, it is prone to torsional deformation due to large inertia during start-stop, which can cause cracks in the keyway and damage to the expansion roller.
The system employs a support and load-bearing mechanism, using electric actuators, wedge blocks, and arc plates to provide uniform stress distribution. Combined with a fixing ring and load-bearing rollers, it supports the inner and outer surfaces of the material roll, reduces the working stress of the expansion roller, and extends the life of the mechanical system.
This achieves uniform stress distribution, extends the service life of the expansion roller, improves the load-bearing capacity of the device, and ensures the effectiveness and stability of the device.
