Further, in the following detailed description of the present application, certain specific details are set forth in order to provide a better understanding of the present application. The present application will be fully understood by those skilled in the art without the details described herein.
Embodiment one: as shown in fig. 1, a jacquard heald lifting mechanism comprises a frame 1, a needle selector 2, a steering mechanism and a eye plate.
The frame 1 comprises a transverse frame and a vertical frame connected with one end of the transverse frame. The transverse frame can be directly placed on the horizontal table top, and the vertical frame is hung on one side of the table top, so that the deployment of the heald lifting mechanism is completed.
The two layers of needle selector 2 groups are arranged on the transverse frame, and each layer of needle selector 2 group comprises four needle selectors 2 arranged side by side. Slide ways 4 are arranged on two sides of the frame 1 corresponding to the upper layer needle selector 2 and the lower layer needle selector 2; both ends of the lifting knife 3 penetrate through the slide ways 4 and are connected with the synchronous belt 5; the lifting knife 3 is used for being contacted with or separated from a lifting wire hook of the needle selector 2 under the drive of the driving mechanism, and the position of the lifting wire hook is controlled.
