AI Technical Summary
The existing blown film machine's traction and rotation mechanism is prone to roll material accumulation, unstable operation, and poor adaptability to films of different specifications and materials, affecting production efficiency and film quality.
A traction and rotation mechanism was designed, which includes a rotary drive assembly, a herringbone clamp, a clamping roller, and a rotary traction mechanism. The rotary drive assembly drives the support platform and the rotary traction mechanism, which work together with multiple gears to achieve uniform traction and stable conveying of the roll material. The mechanism can also adapt to films of different specifications and materials through a spacing adjustment assembly and a microporous structure for the air roller.
It achieves uniform spreading of the roll material, avoids accumulation, improves production efficiency and film quality, enhances equipment stability and adaptability, simplifies operation procedures, and reduces manual labor intensity.
