AI Technical Summary
Existing stone slab feeding devices have problems with insufficient lifting stability and unreliable stone slab release, leading to frequent accidents such as off-center loading and derailment, large deformation, and stone slab adhesion, which affect the automation level and yield of stone production lines.
The system employs a dual-rail anti-eccentric lifting mechanism and a release mechanism that combines push block and vacuum breaking, along with a magnetically coupled translation component and a high-rigidity frame, to ensure the stability and reliability of slab feeding. Intelligent scheduling is achieved through a PLC control system.
It achieves zero chain slippage and zero adhesion in slab feeding, improves lifting and positioning accuracy and release reliability, reduces off-center load risk and adhesion accident rate, and improves the stability and efficiency of automated production.
