The invention discloses a
yarn carrier capable of automatically replenishing and discharging yarns. The
yarn carrier comprises a
yarn carrier main body, a yarn replenishing-discharging mechanism, a yarn carrying mechanism and a driving mechanism, wherein the yarn replenishing-discharging mechanism, the yarn carrying mechanism and the driving mechanism are arranged on the yarn carrier main body, the yarn replenishing-discharging mechanism is located at the upper part of the yarn carrier main body, the yarn carrying mechanism is located in the middle of the yarn carrier main body, and the driving mechanism is located at the bottom of the yarn carrier main body. According to the yarn carrier, the problem that the yarns need to be replenished and discharged by manually changing the
fineness of knitted yarns, changing the motion track of the yarn carrier or introducing impurities in a knitting process of a variable cross section of an existing yarn carrier is solved. The invention further discloses a three-dimensional knitting
machine utilizing the yarn carrier. The three-dimensional knitting
machine comprises a knitting stander, a drive-off motor, a pre-forming chuck, a
chassis and a plurality of yarn carriers, wherein the drive-off motor, the pre-forming chuck, the
chassis and the yarn carriers are arranged on the knitting stander, the
chassis is located at the lower part of the knitting stander, the yarn carriers are arrayed and mounted on the chassis, and the pre-forming chuck is located right above the yarn carriers and is fixed on the knitting stander through a connecting rod.
