Yarn carrier capable of automatically replenishing and discharging yarns and three-dimensional knitting machine utilizing yarn carrier

Abstract

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.

Description

technical field [0001] The invention belongs to the field of three-dimensional knitting machine equipment, and relates to a yarn carrier that can automatically increase or decrease yarn. The invention also relates to a three-dimensional knitting machine using the yarn carrier. Background technique [0002] Three-dimensional weaving technology is a new type of composite material manufacturing technology. The composite material prefabricated parts made by it have many advantages such as light weight, high strength, and excellent mechanical properties. It has been widely used in the field and has been continuously expanded to the civilian field. [0003] The three-dimensional knitting machine is a device for weaving three-dimensional braided fabrics. The yarn carrier 4 moves regularly on the chassis 5, so that the yarns are interwoven in space to form prefabricated parts with equal or variable cross-sections. The preforming chuck 2 is driven by the lead-off motor 1 to leave t...
