Description

Technical Field

[0001] The utility model relates to the technical field related to wire feeders, in particular to a wire feeder with a straightening function. Background Art

[0002] A wire feeder generally includes a frame, two corresponding wire feeding wheels arranged on the frame, and a driving assembly that drives the two wire feeding wheels to rotate to feed the wire. Although a wire feeder of this structure can be used, the disc-shaped welding wire has a certain degree of curvature after being output by the wire feeder. If the curvature is too large, the welding quality will be affected during welding. How to design a wire feeder that can straighten the welding wire has become a technical problem that urgently needs to be solved. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide a wire feeder with a straightening function to solve the above technical problems.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0005] The straightening adjustment assembly is installed on the frame, one end of which is drivingly connected to the upper end of the straightening seat, and is used to drive the straightening seat to swing with the connecting shaft as the rotation axis and to link the straightening wheel with the welding wire for straightening.

[0006] By adopting the above technical scheme, when the welding wire passes through the lower part of the second annular groove on the support wheel to the left, and passes through the lower part of the first annular groove on the first wire feeding wheel, the straightening seat is driven by the straightening adjustment component to swing with the connecting shaft as the rotation axis. The swing of the straightening seat can link the straightening wheel to move up and abut against the welding wire, so as to straighten the welding wire and keep the welding wire in good rigidity. After straightening, the driving component drives the first wire feeding wheel and the second wire feeding wheel to rotate to output the straightened welding wire. When the welding wire is output from the welding gun, the straightness is good, which can ensure the welding quality of the welding wire.

[0007] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0008] In some embodiments, the straightening adjustment assembly includes an adjustment handle, an adjustment rod, and a spring. A rotating shaft is rotatably fitted on the straightening seat. The left end of the adjustment rod is threadedly fitted with a threaded hole on the rotating shaft, and the right end passes through a hole on the frame and is connected to the adjustment handle. The spring is sleeved on the adjustment rod, and its left end elastically abuts against the straightening seat, and its right end elastically abuts against the frame. Thus, when the adjustment handle is manually screwed to drive the adjustment rod to rotate, the other end of the adjustment rod is threadedly fitted with a threaded hole on the rotating shaft, and the adjustment rod rotates to drive the rotating shaft to move. The rotating shaft moves to link the straightening seat to rotate clockwise or counterclockwise with the connecting shaft as the rotating axis. The straightening seat rotates to link the straightening wheel to perform height adjustment. The height adjustment of the straightening wheel can not only adjust the degree of correction of the welding wire, but also meet the straightening adjustment needs of welding wires of different diameters.

[0009] In some embodiments, the left end of the adjustment handle is provided with a notch extending vertically, and the adjustment rod extends into the notch and is hinged to the adjustment handle through a hinge rod. Thus, when the right end of the adjustment handle is manually driven to rotate with the hinge rod as the rotation axis, the adjustment handle can be transformed from a horizontal state to a vertical state.

[0010] In some embodiments, a through groove is provided on the alignment seat, the threaded hole passes through the rotating shaft, and the through groove corresponds to and is connected to the threaded hole.

[0012] In some embodiments, the straightening wheel is provided with a third annular groove corresponding to the second annular groove, the top and bottom of the adjustment handle are provided with flat surfaces, and the distance between the hinged rod and the left end surface of the adjustment handle is smaller than the distance between the hinged rod and the top surface of the adjustment handle and the distance between the hinged rod and the bottom surface of the adjustment handle. Thus, when the adjustment handle changes from a horizontal state to a vertical state, the adjustment rod can be driven to move rightward, and the linkage straightening seat can drive the straightening wheel to move downward.

[0013] In some embodiments, the frame has a wire inlet hole at the right end and a wire outlet hole at the left end, and the wire inlet hole and the wire outlet hole correspond to the lower part of the first annular groove.

[0014] In some embodiments, the frame includes a base and an adjustment seat, the first wire feeding wheel is rotatably engaged on the base, the second wire feeding wheel is rotatably connected to the adjustment seat, the left end of the adjustment seat is hinged to the base through a hinge shaft, and the right end of the base is connected to an adjustment handle that abuts the adjustment seat and is used to fine-tune the height of the right end of the adjustment seat.

[0015] In some embodiments, the upper end of the adjustment handle is hinged to the base, and both the base and the adjustment seat are provided with an avoidance notch that allows the adjustment handle to swing forward, a limiting groove is provided at the bottom of the adjustment seat, and the adjustment handle is provided with a limiting portion placed in the limiting groove.

[0016] In some embodiments, the drive assembly includes a motor, a reducer, a first gear and a second gear, the driving end of the motor is connected to the reducer, the reducer is installed on the rear side of the frame, and its output shaft extends into the frame, the first gear and the first wire feeding wheel are installed on the output shaft of the reducer, the second gear is meshed under the first gear, and rotates together with the second wire feeding wheel to cooperate with the mounting shaft connected to the frame.
