[0018] It should be noted that when different textile threads are drawn on the drawing frame 1, the pressure sensor 102 of the upper roller detects the change of pressure: if the pressure increases, it is determined that the textile thread is thick, and if the pressure decreases, it is determined that the textile thread is thin. The pressure sensor 102 transmits a signal to the control box 103 to trigger the first motor 104 to reverse, and drives the moving frame 107 to move up and down through the ball nut pair transmission of the threaded rod 105 and the moving sleeve 106 to adjust the drawing parameters.
