| 摘要 |
The invention provides a welding stick supply mechanism which can reduce radial load suffered by a feed device, comprising a feed member (53) of a feed roller (535) rotating in a first direction; a pressure member (54) of a pressure roller (545) rotating in the first direction; and a load reduction member (55) of a load reduction rotary member (555) rotating in the first direction. The feed member (53) comprises a rotary shaft of the feed roller (535) extending in the first direction; the pressure roller (545) applies force (F1) in a second direction (X2) perpendicular to the first direction under the condition that a welding stick (891) is clamped between the pressure roller and the feed roller (535), thereby reducing the force (F2) to the feed member (53) in a third direction (X3) by the load reduction rotary member (555). |
