Description

Technical Field

[0001] The utility model belongs to the technical field of I-wheel wire arrangement, and in particular relates to an I-wheel wire arrangement mechanism and a welding wire unwinding machine. Background Art

[0002] Welding wire is a welding material used as a filler metal or a conductive metal wire, including carbon steel welding wire, low alloy structural steel welding wire, alloy structural steel welding wire, stainless steel welding wire and non-ferrous metal welding wire, etc. The surface of the welding wire is not coated with anti-oxidation flux. It is used as a filler metal in gas welding and tungsten inert gas shielded arc welding; in submerged arc welding, electroslag welding and other metal arc shielded arc welding, it is both a filler metal and a conductive electrode.

[0003] After the welding wire is produced, it is first wound on an I-shaped wheel, then unwound through a wire unwinding machine equipped with an I-shaped wheel, and finally wound onto a wire reel through a layer winding machine. After being straightened and pressed by the layer winding machine, the welding wire will be wound on the wire reel in a tight and orderly manner. The welding wire on the wire reel is wound in regular layers and the weight specifications of the welding wire wound on the wire reel are unified for easy shipment.

[0004] In the process of unwinding the existing welding wire unwinding machine, if there is a phenomenon of tangled wires, the wire unwinding is done manually, and the welding wire reel and the I-shaped wheel are reversed so that the tangled wires on the welding wire reel are wound back onto the I-shaped wheel. Since the moving speed of the wire pressing mechanism and the straightening mechanism of the layer winding machine is set to match the rotation of the welding wire reel, during the reverse wire unwinding process, the wire pressing mechanism and the straightening mechanism of the original layer winding machine will not keep matching with the rotation of the I-shaped wheel. At this time, the I-shaped wheel wire arranging mechanism is needed to arrange the wires so that the tangled wires are rewound on the I-shaped wheel in an orderly manner. When the existing I-shaped wheel wire arranging mechanism is arranging the wire, the contact between the welding wire and the lever will damage the welding wire and affect the welding performance of the welding wire.
