Abstract
The wire feed mechanism includes a feed roll, a pressure roll, a pressure arm, and a pressure mechanism. The feed roll rotates around a rotation axis. The pressure roll is displaceable relative to the feed roll. The pressure arm has a first end and a second end that are separate from each other, and rotatably supports the pressure roll. The pressure mechanism engages with the pressure arm so that a pressure force is applied from the pressure roll to the feed roll with a wire held between the feed roll and the pressure roll. A force-receiving portion is provided at an end of the pressure arm. When the pressure roll presses the feed roll, the pressure mechanism applies a force to the force-receiving portion in a direction that is substantially parallel to the direction in which the wire is fed.
Claims8
A wire feed mechanism comprising:
- a feed roll that rotates around a rotation axis;
- a pressure roll displaceable relative to the feed roll;
- a pressure arm having a first end and a second end that are separate from each other, the pressure arm rotatably supporting the pressure roll;
- and
- a pressure mechanism that engages with the pressure arm so that a pressure force is applied from the pressure roll to the feed roll with a wire held between the feed roll and the pressure roll,
- wherein the pressure arm is pivotable around a first shaft that is located at the first end and is parallel to the rotation axis, the pressure arm including a force-receiving portion provided at the second end, and
- when the pressure roll presses the feed roll, the pressure mechanism applies a force to the force-receiving portion in a direction that is substantially parallel to a direction in which the wire is fed.
