Referring to fig. 1 to 2, as the embodiment of the present invention, a seam machine wire drawing mechanism includes a bottom plate 100, be provided with fixed block 110 on the bottom plate 100, be provided with wire drawing tube head assembly 200 on the fixed block 110, wire drawing tube head assembly 200 including set up in center block 210 on the fixed block 110, center block 210 includes rotating part 211 and extension 212, be fixed with outside extension wire drawing return bend 220 on the extension 212, the wire drawing return bend 220 other end is provided with wire drawing collet 230, rotating part 211 is opened and is had fixed orifices 213, the fixed orifices 213 top is provided with first drive arrangement 300, first drive arrangement 300 is connected with first transmission shaft 310, first transmission shaft 310 passes fixed orifices 213 and can drive rotating part 211 follows first transmission shaft 310 rotates. When the drawing device works, the first driving device 300 drives the first transmission shaft 310 to rotate, the first transmission shaft 310 drives the central block 210 to rotate, the drawing elbow 220 and the drawing chuck 230 arranged on the elbow rotate together, when the drawing chuck 230 reaches a position to be drawn, a wire body is clamped, at the moment, the first driving device 300 rotates reversely, the drawing chuck 230 drives the wire body to return to the initial position of the drawing chuck 230, the drawing chuck 230 is loosened, and the wire is delivered to the next process. In this embodiment, the first driving device 300 drives the first transmission shaft 310 to rotate the rotating portion 211 on the central block 210 along the first transmission shaft 310, so as to drive the wire drawing bent tube 220 disposed on the extending portion 212 to rotate, and the wire drawing collet 230 at the tail end of the bent tube clamps or releases the wire harness after reaching a specified position. The device adopts rotary wire drawing, occupies small space, has simple structure and is convenient to operate.

Optionally, in an embodiment of the thread drawing mechanism of the seaming machine, the central block 210 is Y-shaped, and includes two symmetrically arranged extension portions 212, each of the extension portions 212 is provided with a symmetrically arranged thread drawing elbow 220, and each of the thread drawing elbows 220 is provided with the same thread drawing collet 230. The symmetrical arrangement of the wire drawing bent pipe 220 and the clamping heads enables the two wire drawing processes to be carried out in a reciprocating mode at the same time without mutual influence. The first transmission shaft 310 drives the Y-shaped symmetrical center block to rotate, when the wire drawing chuck 230 on one side clamps the wire harness to be brought back, the wire drawing chuck 230 on the other side is just in the forward wire clamping stroke, and the first driving device 300 can perform wire drawing twice in one stroke, so that the efficiency of the wire drawing process is greatly improved.

Referring to fig. 3, as a modification of the above embodiment, the first driving device 300 is fixed on a fixed rotary block 410, one side of the fixed rotary block 410 is connected to the first transmission shaft 310, the other side of the fixed rotary block 410 is fixed on a second driving device 400, and the second driving device 400 can drive the fixed rotary block 410 to rotate. Preferably, a fixing through hole 420 is formed at a connection position of the rotating fixing block 410 and the second driving device 400, a second transmission shaft 430 extends from the bottom of the second driving device 400, and the second transmission shaft 430 passes through the fixing through hole 420 and can drive the rotating fixing block 410 to rotate along the second transmission shaft 430. When the second driving device 400 drives the fixed rotation block 410 to rotate, the fixed rotation block 410 drives the first transmission shaft 310 to swing, and the central block 210, the wire drawing bent pipe 220 and the wire drawing chuck 230 also swing accordingly. Because the position of the wire is not good sometimes, the wire cannot be smoothly clamped simply by the rotation center block 210 of the first driving device 300, and at this time, the second driving device 400 is added to drive the rotation fixing block 410 to rotate around the second transmission shaft 430, so that the first transmission shaft 310 connected to the rotation fixing block 410 horizontally swings to drive the wire drawing chuck 230 to swing on the horizontal position, so that the wire drawing chuck 230 can reach more positions, and the wire drawing chuck is convenient to cope with various conditions.
