An electronic jacquard card is formed by clamping a plurality of electronic jacquard card drive boards, and has the advantages of simpler structure, convenience in maintenance, low energy consumption and high efficiency.

Description

technical field [0001] The invention relates to a needle selection device for controlling a jacquard machine of a textile machine, in particular to an electronic flower pillow and a driving board thereof. Background technique [0002] The traditional mechanical jacquard machine, the device for controlling the needle selection of the jacquard machine is composed of an iron flower tube, a rotating mechanism and a cardboard with holes. The manufacture of the control pattern cardboard with holes needs to go through programming, punching, threading, fixing and installation A series of cumbersome processes such as cardboard, because a pattern requires a minimum of 3,000 sheets of cardboard, up to hundreds of thousands, and an average of about 5,000 sheets. If the cardboard is punched incorrectly, it will be completely scrapped. In addition, the cardboard cannot be placed for a long time, otherwise it will become soft due to moisture and cannot be used, and storing the cardboard al...

AI Technical Summary

Problems solved by technology

[0007] 1. In the same electronic pattern board, different solenoid valves correspond to different lengths of push pins, which makes the length of push pins different, making maintenance extremely inconvenient, and the push pins are too long and easy to bend and deform, resulting in jamming and increased failures;

[0008] 2. The weight and volume of the electronic card body composed of multiple electronic card boards are large. Installing it on the mechanical jacquard machine will cause the jacquard machine to have a heavy load, large wear, and large power loss. In order to reduce the weight of the electronic card body, Generally, the coil skeleton can only be made of hollow plastic;

[0009] 3. The coil bobbin moves up and down by the action of electromagnetic force. The electromagnetic force must overcome the gravity of the coil bobbin itself and the gravity of the enameled wire and the friction force generated by the large-area contact between the inner side of the coil bobbin and the iron core to slide upward. Most of the power loss is in overcoming its own weight, resulting in power waste;

[0011] 5. The coil frame made of inner hollow plastic will heat and deform when the coil is energized for a long time, causing the inner side of the coil frame and the iron core to be stuck, so that the solenoid valve cannot move up and down, making it impossible to realize "with holes" and "without holes" In addition, the movement stroke of the coil skeleton is too large, resulting in the slow speed;

[0012] 6. Each coil corresponds to an iron core, two permanent magnets, an electromagnetic valve seat, and an electronic pattern plate with 64 permanent magnets. Not only is the cost high, the weight is heavy, the assembly is complicated, and there are many failure points
