The reed is an independent action unit of the jacquard mechanism of the LCL tufting loom. Its action sequence determines the quality of the jacquard. According to the jacquard technology and simulation, the sequence curve of the tufting needle and the loop hook can be obtained. The following conclusions can be drawn: (1) Tufting needle , The timing requirements of the loop-forming hook are: when the tufting needle moves to the bottom stop, the loop-forming hook passes through the vertical position of the tufting needle and moves to the far dead point to ensure that the yarn is tight and the loop-forming hook enters the tufting needle. And the yarn. (2) When looping, the opening of the loop-forming hook should be closed immediately before reaching the far dead point. At this time, the tufting needle is under the horizontal line of the loop-forming hook and stops moving upwards. (3) When cutting pile, the last working cycle is in the loop pile state, then the reed will retreat at a moment after the tufting needle is at the top dead center to ensure the opening of the loop-forming hook in the next jacquard cycle; the previous working cycle For cutting pile, the reed does not move. The above is the timing design of the loop pile of the LCL tufting machine. The timing of the action of the reed is determined, which provides a basis for the selection of the cylinder that drives the movement of the reed, the design optimization of the reed transmission structure, and the selection of the time point for controlling the solenoid valve in the control design.
