AI Technical Summary
The telescopic claw mechanism of existing fiberglass yarn drawing machines has a slow response speed and a long transmission chain on larger machine heads, making it difficult to meet the requirements of high-efficiency applications.
The telescopic claw is directly driven by a piston rod, and an elastic return element is configured on the piston rod. The telescopic movement of the piston rod is controlled by compressed air to achieve radial expansion and contraction. The elastic element is used to maintain the telescopic claw in the state of waiting to be loaded with yarn.
It achieves a short transmission chain, short response time, and fast reaction speed, adapting to the application requirements of larger machine heads and reducing the risk of yarn breakage.
