[0027] The bottom line passes through the wire-making cam 8, the guide wheel 15, the wire outlet 10 and the roller 5, and then passes through the wire guide groove 4 to the upper part of the workbench 3. During the unwinding process of the bottom line, the guide wheel 15 is pressed downward, and the first spring 13 is compressed. When the bottom line breaks, the first spring 13 immediately recovers, driving the connecting seat 14 to rise and triggering the trigger device located between the two guide wheels 15, so that the device stops running, preventing the bottom line from being entangled on other components, which makes it difficult to repair.

[0028] The trigger device includes a fixing frame 16 and a trigger block 18 . The fixing frame 16 is fixedly connected to the control box 6 . A control switch 17 is provided on the fixing frame 16 .

[0037] When the bottom line breaks, the connecting seat 14 rises under the action of the first spring 13, and drives the clamping block 204 to rise synchronously through the connecting rod 22, pressing the broken bottom line inside the positioning groove 21, and the toothed protrusion 205 increases the friction force during clamping to prevent the broken bottom line from falling off.

[0038] The working principle of the thread breaking stop mechanism of the high-speed vertical cylinder interlock sewing machine provided by the utility model is as follows:

[0039] The bottom line passes through the wire-making cam 8, the guide wheel 15, the wire outlet 10 and the roller 5, and then passes through the wire guide groove 4 to the upper part of the workbench 3. During the unwinding process of the bottom line, the guide wheel 15 is pressed downward, and the first spring 13 is compressed. When the bottom line breaks, the first spring 13 immediately recovers, driving the connecting seat 14 to rise and triggering the trigger device located between the two guide wheels 15, and the device stops.

[0040] Compared with the related art, the thread breaking stop mechanism of the high-speed vertical cylinder interlock sewing machine provided by the utility model has the following beneficial effects:

[0041] When the bottom thread breaks, the guide wheel 15 is no longer pressed downward by the bottom thread. At this time, the compressed first spring 13 recovers immediately, driving the connecting seat 14 to rise and trigger the trigger device located between the two guide wheels 15, so that the device stops running and prevents the bottom thread from being entangled on other components, making it difficult to repair.
