The invention relates to a horizontal-woven device, which provides a needle-triangle controller of gear transmission of horizontal-woven device. It comprises: on the triangle bottom plate, a signal disc, a gear plate, a sliding block, a signal generator, a signal sensor and a needle triangle. Wherein, the signal disc is arranged at the back of triangle bottom plate, whose rotational shaft has a gear; the gear is meshed with the rack bar on one side of gear plate; the gear plate is connected to the needle triangle at the front of triangle bottom plate via the sliding block sliding mounted in the relative hole groove of triangle bottom plate; the signal sensor is arranged beside the signal disc; and the signal generator is also arranged beside the signal disc. The invention has the advantages that the transmission structure of gear and rack bar can simplify the transmission line, reduce the transmission process, reduce the matching space and improve the transmission accuracy. And the space of whole transmission device is significantly reduced to fully utilize limited space of triangle bottom plate. |
