[0020] Reference Figure 1-3 , a garment fabric flat knitting machine with a stable conductor, comprising a controller 8, a machine body 1 and a first bracket 2 fixed at the upper end thereof, used to support a second bracket 9, the model of the controller 8 is 80S51, the input end of the controller 8 is connected to the output end of the pressure sensor 6, the output end of the controller 8 is connected to the input end of the servo motor 10, the first bracket 2 and the second bracket 9 are both arranged in an n shape, the controller 8 is fixed on the outer wall of the machine body 1, a plurality of second brackets 9 are slidably inserted at the upper end of the first bracket 2, used to drive the support plate 4 to rise and fall, a slide groove is provided on the outer wall of the second bracket 9, and a guide block 15 is slidably connected to the inner wall of the slide groove, used to keep the second bracket 9 rising and falling in a straight line, one end of the guide block 15 passes through the slide groove and is fixedly connected to the inner wall of the first bracket 2;

[0021] In this embodiment, the upper end of the first bracket 2 is provided with a mounting groove corresponding to the position of the second bracket 9, and a servo motor 10 is fixedly connected to the bottom of the mounting groove for driving the lead screw 11 to rotate. The end of the output shaft of the servo motor 10 is fixedly connected to the lead screw 11 for driving the second bracket 9 to rise and fall. The upper end of the lead screw 11 passes through the mounting groove and the second bracket 9, and the lead screw 11 and the second bracket 9 are threadedly connected. A baffle is rotatably sleeved on the lead screw 11 to prevent debris from entering the mounting groove, and the lower side wall of the baffle is fixedly connected to the upper end of the first bracket 2;

[0022] In this embodiment, the lower end of the second bracket 9 slides through the first bracket 2 and is fixedly connected with a support plate 4 for supporting the spring 3. A support block 7 is provided at the upper end of the support plate 4. A plurality of springs 3 are fixedly connected between the support plate 4 and the support block 7 for supporting the support block 7. A guide rod 5 is slidably inserted in the spring 3 to prevent the support block 7 from tilting. The upper end of the guide rod 5 is fixedly connected to the lower end of the support block 7. The lower end of the guide rod 5 slides through the spring 3 and the support plate 4. A pressure sensor 6 is provided between the support plate 4 and the support block 7 for detecting the pressure value of the support block 7. The model of the pressure sensor 6 is LLBLS-I. The pressure sensor 6 is fixed to the upper end of the support plate 4.

[0023] In this embodiment, a groove is provided at the upper end of the support block 7, and a guide wheel 12 is provided in the groove for guiding the yarn.

[0024] In this embodiment, the yarn is first guided by the wire wheel 12. Since the support block 7 is elastically supported by multiple springs 3, when the yarn is taut, the wire wheel 12 and the support block 7 are pressed down. The support block 7 presses down the pressure sensor 6, and the pressure value is detected by the pressure sensor 6. When it is higher than the setting, the servo motor 10 is started by the controller 8 to drive the screw 11 to rotate. The screw 11 drives the second bracket 9 to descend through the action of threaded engagement. The second bracket 9 drives the support block 7 and the wire wheel 12 to descend through the support plate 4, so as to avoid the yarn from cracking or breaking. After the height is lowered in the above manner, the yarn is loosened a little. At this time, the pressure sensor 6 detects that the pressure is lower than the preset value, and the servo motor 10 is turned off by the controller 8.
