[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] See also Figure 1-4In this embodiment, a button-stitching machine that is easy to replace molds includes a frame 1, a lifting frame 14 and a button-stitching device 2. The button-stitching device 2 is an existing button-stitching device, and its working principle is not described one by one. The button-stitching device 2 is arranged on the frame 1 through the lifting frame 14. A rotating table opposite to the button-stitching end of the button-stitching device 2 is arranged on the frame 1. A plurality of molds 4 are evenly distributed on the circumference of the rotating table, so that any mold 4 can be rotated to the bottom of the button-stitching device 2 through the rotating table. Two fixed splints 12 are arranged between the mold 4 and the button-stitching device 2. A button fixing space is formed between the two fixed splints 12, and the two fixed splints 12 are connected by a driving mechanism, and the fixing space is adjusted by the driving mechanism.

[0017] In this embodiment, when the mold 4 needs to be replaced, the multiple molds 4 above are driven to rotate by the rotating table, so that the required mold 4 is rotated and switched to the bottom of the button-stitching device 2. At this time, the two fixed clamps 12 are located on both sides above the mold 4 to be processed, and are driven by the driving mechanism to move relative to or apart from each other, so that the buttons to be buttoned can be fixed, so that the buttons will be offset when the button-stitching device 2 is buttoning.

[0018] Preferably, as another embodiment of the utility model, the rotating table includes a truncated table 3, the bottom end of the truncated table 3 is rotatably connected to the frame 1 through a bearing, a plurality of molds 4 are evenly distributed on the truncated table 3 with its center point as the center of the circle, a driving motor 8 is arranged under the frame 1, a rotating rod is coaxially connected to the output shaft of the driving motor 8 and the bottom end of the truncated table 3, a sprocket 6 is fixedly mounted on the rotating rod, and the two sprockets 6 are connected by a transmission chain 7.

[0019] In this embodiment, the driving motor 8 is started to drive the rotating rod and the sprocket 6 fixed thereto to rotate, so that the sprocket 6 transmits the transmission to another sprocket 6 through the transmission chain 7, thereby rotating the round table 3 to switch the position of the mold 4.
