Then, the first motor 4 is started. The first motor 4 drives the first belt pulley 5 to rotate, so that the first belt pulley 5 drives the first threaded rod 6 to rotate, thereby driving the moving part 7 to move. The moving part 7 moves towards the fixed seat 1 side and drives the tension shaft 8 to move, squeezing the finished cloth. By adjusting the position of the tension shaft 8, the tension of the finished cloth between the rollers 21 is changed, and the finished cloth is stretched with different tensions to prevent the finished cloth from wrinkling. After that, the second motor 10 and the fourth motor 20 are started synchronously. The second motor 10 drives the rotating part 11 to rotate, thereby driving the take-up reel 12 to rotate to wind up the finished cloth, and the fourth motor 20 drives the third belt pulley 22 to rotate, thereby driving the roller 21 to rotate. The rotation of the roller 21 drives the finished cloth to move.
