Weft detector for water jet looms using molded light-receiving elements

摘要

according to the invention, the water jet loom (Water jet loom) with friends on the administrator, familiar with the chips and the bonding of the protection on thein a flood of permanent decline, poor rate is high, can with ceramic optical element for bonding a single body in the form of optical element and mold shape (shape, make the classification task) for use as the position is clear, whether to have at the same time. sensor the service life of the optical element, the service life can be maintained and semi permanent, can significantly reduce the defective rate, and to.and two, i will be the light sensor to the shielding case (shild) of the sensor from the first stage to remove the noise power, the operation can be reduced to one.
