Abstract

An electronic pattern card or a device used for controlling jacquard machine needle selection is provided to replace the ordinary pattern card, increase weaving efficiency and decrease weaving cost. The working principle is to achieve the two electronic pattern card states of hole and hole-free through a bi-stable state needle selection electromagnetism valve 3. A movable loop 8a and a loop framework 8 are arranged on the bi-stable state needle selection electromagnetism valve. A stopping block 8b is arranged on the loop framework. The iron core 9 and the permanent magnet 10 arranged on the iron core form an excitation system. The excitation system is fixed on an abnormal groove 3b vertically arranged on the electromagnetism valve seat. When a positive electricity current travels through the loop, the movable loop and the loop framework will move upwards and the stopping block 8b will not stop the pushing needle 6 to form the hole state of the electronic pattern card and corresponding longitudinal lines are raised. When a negative electricity current travels through the loop, the movable loop and the loop framework will move downwards and the stopping block 8 b will stop the pushing needle 6 to form the hole-free state of the electronic pattern card and corresponding longitudinal lines will sink.
