Description
本發明是有關於一種縫紉機,特別是指一種縫紉軌跡切換裝置。 The present invention relates to a sewing machine, and more particularly to a sewing track switching device.
一種現有的縫紉機,在進行縫紉作業時,是透過一凸輪轉動時連動位於上方的送布齒上下擺動後,而能進行收線的工作。 An existing sewing machine, when performing sewing operations, can take up the thread by rotating a cam to link the feed teeth located above to swing up and down.
然而,每一種布材在進行收線時,都會有最適合的收線動作(也就是最適合的送布齒擺動軌跡),而單一凸輪的外周輪廓只能對應一種送布齒擺動軌跡,因此在更換其他種布材時,就無法得到最佳的收線效果。 However, each type of fabric has the most suitable take-up action (that is, the most suitable feed tooth oscillation trajectory) when taking up the thread, and the outer peripheral profile of a single cam can only correspond to one feed tooth oscillation trajectory, so when changing to other types of fabric, the best take-up effect cannot be obtained.
因此,本發明的目的,即在提供一種克服先前技術所述缺點的縫紉軌跡切換裝置。 Therefore, the purpose of the present invention is to provide a sewing track switching device that overcomes the shortcomings of the prior art.
於是,本發明縫紉軌跡切換裝置,應用於一具有一架體的縫紉機,該縫紉軌跡切換裝置包含一轉軸單元、一凸輪單元、一升降接觸台,及一操作單元。 Therefore, the sewing track switching device of the present invention is applied to a sewing machine having a frame, and the sewing track switching device includes a rotating shaft unit, a cam unit, a lifting contact platform, and an operating unit.

The cam unit includes a trajectory changing cam disposed around the rotating rod and located between the set set and the cam stop ring and being rotated in conjunction with the rotating rod, and an elastic member abutting against the set set and the trajectory changing cam at two opposite ends to apply an elastic force to the trajectory changing cam in a direction opposite to the set set. The trajectory changing cam has a ring portion and a plurality of self-actuating members. The ring has track parts arranged in sequence along the axis, and at least a part of the outer peripheral contours of the track parts are different from each other. The lifting contact platform is pivoted to the frame and extends above the track change cam, and can be abutted by one of the track parts and swing along the outer peripheral contour. The operating unit includes a bracket arranged on the frame, and a track switching rod arranged on the bracket and extending below the track change cam to carry the ring. The track switching rod can drive the track change cam to move along the rotating rod so that one of the track parts abuts against the lifting contact platform.
