Description

Tile-shaped arc-shaped outer-supporting lifting force pushing barrel mechanism

Technical Field

The invention relates to a pusher mechanism, in particular to a tile-shaped arc-shaped flexible surface outer-supporting lift pusher mechanism.

Background

In the glass fiber tank furnace wire drawing process, because the existing multi-split drawing machine head is mostly longer, in a limited wire drawing space, a robot cannot take out the yarn cluster at the inner side or manually moves the yarn cluster to the outer side for the robot to extract, in order to reduce the burden of workers, some wire drawing machines use a push cylinder function, the push cylinder is in a half-moon shape mostly, the whole row of yarn balls are pushed from the paper cylinder port of the yarn ball at the inner side, because the end face of the yarn ball is not allowed to touch, no matter the yarn ball is directly yarn ball or yarn cake, therefore, the requirements of the pushing cylinder device are high, but in practical use, the problems are mostly wasted in half, and only on the spun yarn cake yarn group can be continued, because the yarn withdrawing process is an external yarn withdrawing process, plastic hard cylinder bodies are used, so-called half-moon and crab pincers are adopted to push the cylinder on the spun yarn, the cylinder cannot be pushed on a yarn withdrawing group in the spun yarn, and the failure rejection rate is high.

Preferably, the machine frame is provided with an upper pinch roller, a lower riding wheel and an orientation key, and the moving frame of the horizontal pushing mechanism is positioned between the upper pinch roller and the lower riding wheel. The upper pinch roller and the lower pinch roller are matched to ensure that the moving frame of the horizontal pushing mechanism can move horizontally.

Preferably, the synchronous gear and the rack of the lifting mechanism are in 2 groups of synchronization. The gear and the rack are lifted synchronously, so that a plurality of yarn groups can be supported at one time.

Therefore, the automatic folding or unfolding of the folding tiles can be utilized, the yarn groups are supported by lifting, and then the plurality of yarn groups are pushed out together by the horizontal pushing mechanism, so that the yarn taking and bobbin unloading work can be completed within the extensible range of the robot, the operation is simple, the manpower and material resources are saved, and the structure is simple and reasonable.
