The heald turret servo 202 is connected to the heald turret assembly via a turret belt or gear for rotating the heald turret and moving the heald to the moving path of the rapier band. The reed servo 207 is connected with the reed clamping device through a coupler so as to drive the reed to move, and yarns need to penetrate through reed gaps of the reed to be aligned with reed knives. The reed cutter servo 206 drives the reed cutter to move through a reed cutter transmission belt, and the reed cutter transmission belt is provided with two reed cutter devices. And (5) the reed knife moves to penetrate the yarns through reed seams to finish the drawing-in operation. The control device 1 may be specifically a PLC controller, a single chip microcomputer, an industrial personal computer, or other control equipment.

The control device 1 controls the drop wire turret servo 203, the heddle turret servo 202, the reed servo 207 and the reed blade servo 206 to cooperate with the rapier band servo 205, respectively. In different processes, the number of threads that need to be threaded in the drop wire, heddle and reed varies. The electric control system provided by the application can control the automatic drawing-in machine to finish drawing-in operation according to process requirements. For example, when two yarns need to be threaded through a heddle, the control device 1 controls the movement of the rapier tape servo 205 twice, and after two yarns are threaded through the same heddle, controls the movement of the heddle turret servo 202 to move the next heddle to the moving path of the rapier tape.

Specifically, the cam servo 208 can drive the lower yarn feeding hook to move through the cam and the conveyor belt respectively, so that the cam and the conveyor belt are matched with each other to complete the actions of yarn feeding, yarn cutting and clamping. Because the lower yarn feeding hook moves independently and cannot be matched with the scissors mechanism, the yarn planting and generating device is also provided with a convex yarn hooking mechanism. The lower yarn shifting hook in the convex yarn hooking mechanism can be matched with the lower yarn feeding hook to unfold the yarns, so that the yarns can be conveniently cut by the scissor mechanism. The convex hook wire servo 209 drives the lower yarn poking hook to move through the lower yarn poking conveying belt, and the convex hook wire servo 209 is also connected with the control device 1.
