Air ring breaking device

Abstract

The invention relates to an air ring breaking device. The air ring breaking device comprises an air ring breaking mechanism I and an air ring breaking mechanism II, wherein the air ring breaking mechanism I is used for wrapping a tube and partial yarns which are exposed to one end of cop yarns, the air ring breaking mechanism II is arranged in the 1/3 position of a cop yarn return line, the air ring breaking mechanism I comprises a fixed bracket, an air ring breaking protecting plate which is installed on the fixed bracket and a yarn guide which is arranged in the air ring breaking protectingplate, and the air ring breaking protecting plate wraps partial cop yarns. The air ring breaking device has the beneficial effects that the yarn unreeling speed is increased, the working efficiency ofan automatic winder is improved, high speed and high yield of the automatic winder are realized, and the product competitiveness is increased.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a balloon rupture device. Background technique [0002] In the process of unwinding the cop, the unwinding yarn will expand around the cop to generate a balloon, such as figure 1 . When the shape of the balloon changes unevenly or exceeds the specified value, the unwinding tension of the yarn will be uneven, and the unwinding cop will fall out of the loop, resulting in yarn breakage. [0003] There are known automatic winders of the SMARO series which have means to limit balloon expansion. The device is above the unwinding cop yarn and has a quadrangular opening structure. The unwinding yarn passes through the device, and the balloon formed by the unwinding is limited within the scope of the device, so as to restrain the upper limit of the balloon expansion and make the unwinding yarn pass through. Stable thread tension to prevent yarn breakage. [0004]...

Problems solved by technology

However, if the yarn unwinding speed is increased, the balloon cannot be fully inflated during yarn unwinding

In particular, when the amount of the yarn to be unwound becomes 1 / 3 or less, the balloon becomes smaller, or because the unwinding speed becomes faster, the unwound yarn is unwound without forming a balloon. The thread is easy to rub against the surface of the yarn layer or the surface of the empty tube. As a result, the bobbin unwinds and the yarn falls off, which in turn causes the yarn to break

In this way, simply increasing the winding speed will frequently cause yarn breakage due to the above-mentioned knock-off, which will instead lead to a decrease in the production efficiency of the automatic winder.
