AI Technical Summary
Existing spiral tube production uncoiling equipment lacks an effective blocking structure when the strip coil is placed as a whole, resulting in a high risk of detachment, affecting production stability and continuity. Furthermore, the fixed blocking structure cannot provide extrusion pressure, making it difficult to align the ends of the strip coil.
The mounting plate and T-shaped extrusion rod structure driven by electric actuators move the mounting plate, mounting block and T-shaped extrusion rod towards the strip steel coil, achieving extrusion flushing and blocking synchronously. Combined with the detachable fastening bolt structure, it can adapt to different thicknesses and support arm expansion degrees, ensuring stability and flexibility.
It effectively prevents steel strip coils from falling off, improves production stability and efficiency of subsequent processes, adapts to different specifications of steel strip coils, is easy to operate, and improves equipment adaptability and performance.
