[0002] In the field of heald drawing-in machines, they are mainly used for weaving healds. Drawing-in is the process of passing the warp yarns through the heald eyelets and reed tooth gaps one by one in a certain order. The operator first passes hundreds of slurried warp yarns of equal length through the healds one by one in order, and then holds a reed knife and passes it through hundreds of narrow slits on the reed in order, and passes hundreds of yarns through the reed slits one by one in order for drawing-in.

The threaded column 4 fixedly connected to the wheel 6 rotates, and the rotation of the threaded column 4 causes the lifting threaded plate 5 threadedly connected to the threaded column 4 to move and lift, and the movement and lifting of the lifting threaded plate 5 causes the back beam 9 fixedly connected to the lifting threaded plate 5 to move and lift, and the movement and lifting of the back beam 9 makes the heald wire enter the heald drawing machine body 12 more smoothly, thereby improving the workers' heald drawing speed, and further improving the work efficiency when the warp wire is inserted into the heald drawing machine body 12. One end of the warp yarn bypasses the back beam 9 and passes through the heald drawing machine body 12 in turn, avoiding the problem that the length of the warp yarn separated from the weaving beam 3 is too long and difficult to control;

[0022] A rotating rod 7 is rotatably connected in the fixed base 1, and a plurality of second bevel gears 8 are fixedly connected to the rotating rod 7. The second bevel gears 8 rotate in the fixed base 1 through the rotating rod 7. The first bevel gear 6 is meshed with the second bevel gear 8 for transmission. The rotating rod 7 is rotated. The rotation of the rotating rod 7 causes the second bevel gear 8 fixedly connected to the rotating rod 7 to rotate.
