[0009] Figure 1 It is a structural schematic diagram of the welding wire conveying device of the present utility model. DETAILED DESCRIPTION
[0010] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0011] like Figure 1 As shown, this embodiment provides a welding wire feeding device, which includes a body 1 and a cover 2. The body 1 is installed with a driving roller 1.3 and main wire feeding rollers 1.2 and 1.4. The driving roller 1.3 drives the main wire feeding rollers 1.2 and 1.4 to rotate. The cover 2 is movably hinged with the body 1. The cover 2 is installed with slave wire feeding rollers 2.2 and 2.3. The main wire feeding roller and the slave wire feeding roller are meshed with each other so that the main wire feeding roller synchronously drives the slave wire feeding roller to rotate. The body 1 is provided with a buckle 1.1, and the cover 2 is provided with a slot 2.1. The buckle 1.1 cooperates with the slot 2.1 so that the cover 2 can be opened or closed. When the cover 2 is closed, the main wire feeding roller and the slave wire feeding roller rotate and contact each other. When the cover 2 is opened, the main wire feeding roller and the slave wire feeding roller rotate and separate from each other. The welding wire feeding device of this embodiment adopts a single-arm double-wheel structure to make it more convenient to install welding wire and adjust the position of the wire feeding roller.
[0012] As a preferred embodiment, the main wire feed rollers 1.2, 1.4 and the slave wire feed rollers 2.2, 2.3 have smooth wheels and toothed wheels, which are coaxially arranged. The smooth wheels are used to transport the welding wire, and the toothed wheels are used to transmit power. The smooth wheels are provided with wire guide grooves on their surfaces, which make the welding wire transportation more stable and less prone to problems such as wire running or wire breakage.
[0013] As a preferred embodiment, the main wire feeding rollers 1.2 and 1.4 have main adjusting bolts 1.5 and 1.6, and the slave wire feeding rollers 2.2 and 2.3 have slave adjusting bolts 2.4 and 2.5. The main adjusting bolts 1.5 and 1.6 can adjust the axial positions of the main wire feeding rollers 1.2 and 1.4, so that the main wire feeding rollers 1.2 and 1.4 can realize linear wire feeding along the wire guide groove, and the slave adjusting bolts 2.4 and 2.5 can adjust the axial distance of the slave wire feeding rollers 2.1 and 2.2, so as to adjust the contact surface between the main wire feeding rollers 1.2 and 1.4 and the slave wire feeding rollers 2.2 and 2.3 when the cover 2 is closed. By adjusting the axial distance and contact surface of the wire feeding rollers, the wire feeding accuracy is higher and the wire feeding force is more stable.
[0014] As a preferred embodiment, the driving roller 1.3 is driven by a stepping motor.
