DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0024] like Figures 1 to 4 As shown, in this embodiment, a welding wire conveying mechanism includes a wire storage rack 1, a flux chamber 2, a welding wire moving rack 3, a welding wire cutting rack 4 and a welding wire clamping rack 5. The flux chamber 2 is located between the welding wire moving rack 3 and the wire storage rack 1 bracket, and the welding wire cutting rack 4 is located between the welding wire moving rack 3 and the welding wire clamping rack 5. The welding wire is conveyed out from the wire storage rack 1, and after passing through the flux chamber 2 and being stained with flux, the welding wire enters the welding wire moving rack 3 to be flattened, and then is pulled out by the welding wire clamping rack 5, and finally is cut by the welding wire cutting rack 4.

[0025] A plurality of wire storage rollers 18 are rotatably connected to the wire storage rack 1. The rolled welding wire is sleeved on the wire storage rollers 18 and is pulled out into the interior of the flux cavity 2 through rotation.

Directional protrusion 19, a wire crimping rack cylinder 20 is provided at the lower end of the welding wire moving frame 3, the driving end of the wire crimping rack cylinder 20 is connected to the lower end of the front wire crimping rack 6, a wire crimping rack motor 21 is fixed to the lower end of the welding wire moving frame 3, the driving end of the wire crimping rack motor 21 is connected to the wire crimping rack lead screw 23 through the first welding wire synchronous belt 22 and the first welding wire synchronous wheel transmission, and a wire crimping rack nut is fixed to the lower end of the rear wire crimping rack 7, and the wire crimping rack lead screw 23 is threadedly connected to the wire crimping rack nut.

[0027] After the welding wire stained with flux enters the welding wire moving frame 3, the pneumatic pressure block 8 at the front end presses downward, and the rear end is controlled by the wire pressing cylinder 9 to move the wire pressing elastic plate 10 downward, and the elastic pressure head 11 lightly presses the welding wire. Similarly, the wire pressing cylinder 9 at the rear end controls the wire pressing elastic plate 10 to move downward, and the elastic pressure head 11 on the wire pressing elastic plate 10 will press on the welding wire. When the welding wire passes through the welding wire moving frame 3, it is guided by the welding wire directional protrusion 19 to ensure the moving direction of the welding wire. In the production of welding wires of different lengths, the wire pressing position is also different. According to actual conditions, the wire pressing frame cylinder 20 can control the forward and backward movement of the front wire pressing frame 6, and the rear wire pressing frame 7 is driven by the wire pressing frame motor 21 through the first welding wire synchronous belt 22 and the first welding wire synchronous wheel to drive the rotation of the wire pressing frame lead screw 23, and the wire pressing frame gong mother is matched to form the forward and backward movement of the rear wire pressing frame 7.

[0030] The welding wire clamping motor 25 drives the second welding wire synchronous wheel 26 and the second welding wire synchronous belt 27, so that the welding wire moving frame 3 moves on the welding wire bottom plate 24, which is responsible for pulling out the clamping end of the welding wire. During the clamping process, the welding wire clamping cylinder 16 controls the lateral movement of the welding wire movable plate 17, and cooperates with the welding wire fixing plate 15 which is a fixed structure itself to clamp the welding wire together through the guidance of the slide rail and the slider.
