Embodiment approach
[0030] As a preferred embodiment of the present invention, a pulley block 6 is arranged above the detection circuit board 3 , and the electromagnet 1 is arranged on the pulley block 6 . The wire connector 2 is connected on the pulley block 6, and the up and down movement of the wire connector 2 is controlled by the pulley block 6. Specifically, the electromagnet 1 is used to control the pulley block 6 to rise or fall following the mechanical structure. In this embodiment, the pulley block 6 is controlled by the electromagnet 1, and those skilled in the art should understand that using the electromagnet 1 to control the pulley block 6 is only one of the many implementations of the present invention. Obviously, those skilled in the art The movement of the pulley block 6 can be controlled in other alternative ways, so as to further control the movement of the line connector 2 in the vertical direction.

The invention discloses a method and a device for quickly detecting pattern knitting errors of a jacquard machine. The device includes an electromagnet, a wire connector, a detection circuit board, a bottom board, and a jacquard needle. The wire connector can move vertically, and the inside of the wire connector is provided with a magnetic steel, and the wire connector is connected with the jacquard needle through a lead wire. The bottom board is arranged under the detection circuit board, and both the detection circuit board and the bottom board include a plurality of through holes, a magnetic sensor is arranged on the detection circuit board, and a wire connector is connected with a lead wire and passes through the through holes of the detection circuit board. The present invention can quickly identify whether there is a knitting error in the current weft under the premise of normal knitting speed, and if there is a weaving error, it can immediately send a stop signal, which is convenient for workers to eliminate errors and reduces the reject rate caused by pattern errors.
Description
technical field [0001] The invention relates to a weaving device and method, more specifically, to a method and device for quickly detecting pattern knitting errors of a jacquard machine. Background technique [0002] Jacquard machine is a kind of textile tool. Ordinary looms can only weave plain fabrics, and only Jacquard machines can weave fabrics with complex patterns. [0003] On the traditional jacquard machine, the cardboard is set on the flower tube, and one cardboard is turned over every weft weaving, and the flower tube is pressed against the horizontal needle once. When there are holes on the pattern plate, the head end of the horizontal needle extends into the hole of the pattern plate and the flower tube, so that the hook end of the straight needle is still hanging on the handle. When the lifting knife rises, the straight needle rises accordingly, and the heddle is driven by the first thread hook and harness to lift. At this time, the warp thread that penetrates...
