A multi-strand adjustable FDY polyester semi-dull retwisted black yarn twisting machine
This utility model relates to the field of twisting machine technology, and in particular to a multi-strand adjustable FDY polyester semi-dull retwisted black yarn twisting machine, including a base, a first support block fixedly connected to the upper surface of the base, and a first connecting column rotatably connected to a rotating hole in the top of the first support block. The surface of the first connecting column is fixedly fitted with a connecting block, and threaded rods are fixedly connected to the four sides of the connecting block. A raw material bobbin is fitted on the surface of each threaded rod. The machine can control the resistance to the rotation of the raw material bobbin. When the threaded column is rotated, the force of the spring on the square plate can be changed. Then, through the cooperation of the hemispherical block and the arc rolling track on one side of the raw material bobbin, the friction force on the raw material bobbin can be adjusted, so as to avoid the raw material bobbin rotating too fast under the pull of the yarn, and prevent the yarn from being released too much and loose, which would cause problems such as tangling and knotting.
