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.

Embodiment Construction

[0020] like Figure 1-3 As shown in the figure, a balloon rupture device includes a balloon rupture mechanism I1 that wraps a bobbin exposed at one end of the cop 6 and a part of the yarn, and a balloon rupture mechanism II2 arranged at 1 / 3 of the bobbin withdrawal line. The balloon rupture mechanism I2 includes a fixed bracket 3, a balloon rupture shield 4 installed on the fixed bracket 3, and a yarn guide 5 is provided in the balloon rupture shield 4; Part of the cop wrap. The balloon rupture device II2 includes a balloon generator 8, a cylinder 7 connected to the balloon generator 8 for driving its movement, a detection device 9 for detecting the yarn unwinding position, and a control device 10 for controlling the action of the cylinder. ; The detection device 10 is arranged at 1 / 3 of the cop yarn withdrawal line, and the cylinder is located above the detection device. The initial state of the cylinder is a contracted state. The cross section of the balloon rupture plate...

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]...
