Yarn breaking warning device

Abstract

The invention relates to a yarn breaking warning device, and aims at solving the problem that the product quality is influenced when the yarn breaking cannot be found in time during spinning in the prior art. The yarn breaking warning device comprises an installing seat, a yarn breaker and a tensioning device, wherein the yarn breaker is arranged on the installing seat, the tensioning device is arranged on the yarn breaker, the yarn breaker comprises a casing, a warning circuit and a hollow metal ball, the warning circuit is arranged in the casing, the hollow metal ball is used for controlling the on-off state of the warning circuit, a round tube through which yarns pass is arranged at the outer side of the casing, the diameter of the hollow metal ball is 2 / 3 to 4 / 5 of the inner diameter of the round tube, the upper end of the round tube is provided with a loudspeaker-shaped groove which has the larger upper part and the smaller lower part and is communicated with the round tube, the lower part of the inner side wall of the round tube is provided with two disconnected metal blocks, the two metal blocks are connected with the warning circuit, and in addition, the warning circuit is switched off between the two metal blocks. The hollow metal ball is arranged in the yarn breaking warning device, the mass of the metal ball is smaller, and when the yarn breaking occurs, the metal ball can fall into the round tube to be connected with the two metal blocks, so the warning circuit is conducted, the warning starts, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to a yarn breaking alarm device. Background technique [0002] In the weaving process, due to yarn quality problems or other reasons, thread breakage often occurs.
