Warping machine yarn break detection device

Abstract

The present invention relates to a yarn break detection device of a warping machine with a collecting plate. The device is fixed on both sides of a left vertical plate, a middle vertical plate and a right vertical plate in a frame with angle seats. Multiple layers of front yarn guide plates and rear yarn guide plates are installed at a certain interval up and down. Between the two plates of each layer, there is a support rod.

Description

Technical Field

[0001] The invention relates to the field of textile machinery, in particular to a yarn breakage detection device for warping equipment. Background Art

[0002] Warping is an important process in weaving, and the warping machine is an important process equipment in textile industry. The yarn break detection device is a necessary function in the warping process. At present, the yarn break detection devices equipped on the warping machines are either on the creel, on the headstock, or between the headstock and the creel after the yarn is formed into a piece. The detection methods include falling sheet contact type, infrared photoelectric type, and photographic type. However, due to the relationship between the detection position and the performance of the detection method, the yarn breakage sometimes does not stop automatically, there are many false operations, the yarn friction affects the tension, the broken end signal output time is long, and the cost is high, which affects the quality of warping. It is urgent to develop a new type of warping yarn break detection device. Summary of the invention
