[0034] A wire drawing device with emergency self-stopping comprises a wire drawing device body 1, and wire drawing bearing wheels 2 which are rotatably arranged on the left and right sides of the wire drawing device body 1 through bearings; a traction feed nozzle 3 is arranged at the left end of the wire drawing device body 1, and a self-stop mechanism is arranged at the left end of the wire drawing device body 1; the self-stop mechanism comprises a bearing platform 4, and the bearing platform 4 is fixedly installed above the left end of the wire drawing device body 1; wherein the front end rotating shafts of the symmetrically arranged wire drawing bearing wheels 2 are mutually connected through a sprocket mechanism 5, and the wire drawing bearing wheels 2 are used to carry and guide the drawn wire;

[0035] The traction feed nozzle 3 at the left end of the wire drawing device body 1 is a vertebral structure with a larger left side and a smaller right side, and the traction feed nozzle 3 passes through the traction wire, and prevents the wire from jumping and falling off during the stretching process by the traction feed nozzle 3; the self-stop mechanism includes a load-bearing bracket 6, and the bottom end of the load-bearing bracket 6 is fixedly installed on the front and rear sides of the top surface of the load-bearing platform 4, and the top ends of the front and rear load-bearing brackets 6 are provided with positioning shafts 7, and the front and rear sides of the positioning shafts 7 are rotatably connected to the bottom ends of the flip locking plates 8; the inner sides of the symmetrically arranged flip locking plates 8 are provided with guide grooves 9, and the top ends of the front and rear flip locking plates 8 are connected to each other by quick-release lock buckles 10, and the front and rear flip locking plates 8 are limited by the guide grooves 9 provided inside for the wire;

[0037] like Figure 1 As shown, first, the wire end drawn out by the wire drawing device body 1 passes through the traction feed nozzle 3, and the traction feed nozzle 3 is used to limit the jumping of the wire during the movement, so that the wire can always be set on the top of the wire drawing bearing wheel 2, and then the wire drawing bearing wheel 2 meshed and connected by the sprocket mechanism 5 can rotate synchronously, thereby reducing the wear during the movement of the wire and improving the smoothness of the wire drawing movement;

[0038] Furthermore, a carrying platform 4 is fixedly provided on the left end of the wire drawing device body 1, and the carrying platform 4 lifts the positioning shaft 7 and the flip locking plate 8 through the carrying bracket 6, and then guides the wire to between the front and rear flip locking plates 8, so that the wire is located in the guide groove 9 opened on the inner side of the flip locking plate 8, and then flips the flip locking plate 8 connected by the positioning shaft 7, and locks the front and rear flip locking plates 8 by the quick-release lock buckle 10 at the top, thereby preventing the wire from falling off during stretching and moving.

[0039] Embodiment 2: In order to solve the problem that the existing emergency stop mechanism cannot achieve the emergency stop effect in the first time, this embodiment adopts the following technical scheme, and drives the transmission roller 11 and the transmission rod 12 inside the flip locking plate 8 to rotate through the normally moving wire, so that the centrifugal latch 16 inside the self-stop positioning disk 13 will not rotate outward under the restriction of the resistance spring 18, thereby ensuring that the emergency self-stop device 17 at the bottom will not be triggered, thereby ensuring the normal operation of the wire drawing device body 1;

[0040] Furthermore, when the broken wire drives the transmission roller 11 and the transmission rod 12 to rotate rapidly, the centrifugal force of the rotation is greater than the pulling force of the resisting spring 18, and the centrifugal latch 16 is thrown outward, and then engaged in the locking positioning groove 15 inside the automatic stop positioning disk 13, so as to lock the rotating transmission gear 14 with the transmission rod 12 and the transmission roller 11, so as to clamp and position the wire, and the stopped transmission gear 14 is detected by the emergency stop device 17 below, and the entire wire drawing device body 1 is stopped by the emergency stop device 17;

[0041] The self-stop mechanism includes a self-stop positioning disk 13, and transmission gears 14 are rotatably arranged on both the front and rear sides of the self-stop positioning disk 13 through bearings, and the internal rotating shaft of the transmission gear 14 is snap-connected to the bottom end of the transmission rotating rod 12, and the transmission gears 14 on the front and rear sides are meshed and connected with each other; the self-stop positioning disk 13 included in the self-stop mechanism is fixedly installed on the middle of the top surface of the carrying platform 4, and locking positioning grooves 15 are provided on both the left and right sides of the self-stop positioning disk 13, and centrifugal latches 16 are rotatably arranged on the bottom surfaces of the transmission gears 14 on the front and rear sides of the self-stop positioning disk 13 through bearings;

[0043] like Figure 3 , Figure 6As shown, the outer wall of the wire moving inside the flip locking plate 8 is in contact with the transmission roller 11 inside the flip locking plate 8, so that the wire drives the transmission roller 11 and the transmission rod 12 to rotate, and then the transmission rod 12 is installed between the transmission gear 14 inside the self-stop positioning plate 13, and the rotating transmission rod 12 drives the mutually meshing transmission gears 14 to rotate. When in normal transmission, the centrifugal latch 16 above the transmission gear 14 will not rotate outward under the restriction of the resistance spring 18, thereby ensuring that the emergency self-stop device 17 at the bottom will not be triggered, thereby ensuring the normal operation of the wire drawing device body 1;

[0044] Furthermore, when the wire above the wire drawing device body 1 breaks, the broken wire is guided by the traction feed nozzle 3 arranged in the vertebral structure, and the broken wire under tension will move rapidly, thereby driving the transmission roller 11 and the transmission rod 12 to rotate rapidly. When the transmission gear 14 rotates rapidly, the centrifugal pin 16 on its surface is thrown outward under the action of centrifugal force, and then engages in the locking positioning groove 15 inside the automatic stop positioning disk 13, so as to lock the rotating transmission gear 14 with the transmission rod 12 and the transmission roller 11, so as to clamp and position the wire, and prevent the wire from shrinking to the inside of the wire drawing device body 1 and affecting the subsequent resumption of work. The transmission gear 14 that stops rotating is detected by the emergency stop device 17 below, and then the entire wire drawing device body 1 is stopped by the emergency stop device 17.
