[0029] In this embodiment, when adjusting the tension amplitude of the tensioning wheel 4, the second electric push rod 701 is started. After the second electric push rod 701 is started, it drives the rod slot 8 to move forward and backward. When the rod slot 8 moves forward and backward, it drives the second wheel frame 3 to move synchronously. When the second wheel frame 3 moves, it drives the tensioning wheel 4 to move synchronously. In this way, when the tensioning wheel 4 adaptively adjusts the tension through the spring 503, the amplitude of the back and forth movement of the tensioning wheel 4 is limited by the position of the rod slot 8, thereby achieving the purpose of adjustable tension.

[0030] like Figure 1 and Figure 4 As shown, a mounting frame 9 is fixedly installed on the outside of the frame 1 away from the second wheel frame 3, a first electric push rod 10 is fixedly installed on the outside of the mounting frame 9, a first wheel frame 11 is fixedly installed on the output shaft end of the first electric push rod 10, and a guide wheel 12 is movably installed inside the top end of the first wheel frame 11;

After the first electric push rod 10 is started, the first wheel frame 11 is pulled back to one side of the mounting frame 9. When the first wheel frame 11 moves, it drives the guide wheel 12 at the top inside to move synchronously. Then, the line can be conveniently placed on the front side of the tensioning wheel 4. When the threading is completed, the guide wheel 12 is reset by controlling the first electric push rod 10, and the tensioning wheel 4 is reset by controlling the second electric push rod 701.

[0034] Working principle: when adjusting the tension amplitude of the tensioning wheel 4, the second electric push rod 701 is started. After the second electric push rod 701 is started, it drives the rod slot 8 to move forward and backward. When the rod slot 8 moves forward and backward, it drives the second wheel frame 3 to move synchronously. When the second wheel frame 3 moves, it drives the tensioning wheel 4 to move synchronously. In this way, when the tensioning wheel 4 adaptively adjusts the tension through the spring 503, the amplitude of the back and forth movement of the tensioning wheel 4 is limited by the position of the rod slot 8, thereby achieving the purpose of adjustable tension; when the rod slot 8 controls the second wheel frame 3 and the tensioning wheel 4 to retreat, the first electric push rod 10 is started. After the first electric push rod 10 is started, the first wheel frame 11 is pulled back to one side of the mounting frame 9. When the first wheel frame 11 moves, it drives the guide wheel 12 at the top of the interior to move synchronously, and then the line can be conveniently placed in the front side position of the tensioning wheel 4. When the threading is completed, the guide wheel 12 is reset by controlling the first electric push rod 10, and the tensioning wheel 4 is reset by controlling the second electric push rod 701 at the same time, so that the threading can be quickly performed without being blocked.
