Solidification weft catching device

Abstract

The invention provides a solidification weft catching device which comprises a solidification plate, a position determination component, weft catching devices and a two-dimensional moving device. The solidification plate is arranged at a weft catching end opposite to a nozzle of a weaving machine, the position determination component is used for determining the positions of weft yarns, the two-dimensional moving device is used for positioning the solidification plate, the weft catching devices are arranged in front of the solidification plate, the position determination component is a capacitive screen arranged on the surface of the solidification plate, rings adhered with liquid films are further arranged in front of the solidification plate, and the position determination component is connected with a control module for controlling the two-dimensional moving device. The solidification weft catching device has the advantages that the contact positions of the weft yarns are sensed by the position determination component, the ends of the weft yarns with liquid can be solidified by the solidification plate, information of the positions of the weft yarns is transmitted to the control module by the position determination component, the control module drives the two-dimensional moving device to shift the solidification plate and the weft yarns to weft yarn insertion target positions, and accordingly the weft catching devices can accurately catch wefts.

Description

Technical field [0001] The invention relates to the field of shuttleless looms, in particular to a solidifying weft catcher for shuttleless looms. Background technique [0002] The common basic feature of shuttleless looms is to separate the weft yarn package from the shuttle, or to carry only a small amount of weft yarn to replace the large and heavy shuttle with a small and light weft insertion device, which provides favorable conditions for high-speed weft insertion . In the supply of weft yarn, the bobbin package is directly used, and it enters the weft insertion mechanism through the weft storage device, so that the loom gets rid of the frequent weft filling action. Therefore, the use of shuttleless looms is of great significance for increasing fabric varieties, adjusting fabric structure, reducing fabric defects, improving fabric quality, reducing noise, and improving working conditions. The speed of shuttleless looms is high, and the efficiency is usually 4-8 times ...

AI Technical Summary

Problems solved by technology

[0003] Since the shuttleless loom does not have a shuttle to guide the weft yarn to fly in the shed, and the weight of the weft yarn itself is very light, the weft yarn is easily disturbed by air resistance, impurities or gravity during the transmission process. The predetermined weft insertion coordinates are relatively inaccurate during installation. Once the allowable error range of the weft catcher is exceeded, it is easy to cause weft detachment accidents.
