The invention discloses a piezoelectrically actuated yarn guide head, and belongs to the technical field of driving devices of yarn guide heads of thread regulators in seamless underwear machine equipment. The yarn guide head includes a yarn guide head body, a base rod, tooth-shaped rings and piezoelectric ceramic pieces, wherein tooth-shaped ring mounting counter bores are formed in the two ends of the base rod, the axes of the tooth-shaped ring mounting counter bores intersect with the axis of the base rod, and the tooth-shaped ring and the piezoelectric ceramic piece are arranged in each tooth-shaped ring mounting counter bore from inside to outside; a shaft sleeve penetrates through the tooth-shaped ring at one end of the base rod, a square shaft is connected into an inner hole of the shaft sleeve in a penetrating mode, and two ends of the square shaft extend out of the tooth-shaped ring mounting counter bore in a suspended mode; a connector is installed in the tooth-shaped ring at the other end of the base rod in a penetrating mode, the yarn guide head body is mounted at the end of the base rod in an attached mode and located at the bottom of the tooth-shaped ring mounting counter bore, a hole corresponding to the tooth-shaped ring mounting counter bore is formed in the yarn guide head body, and the bottom of the connector extends into the hole and is fixed with the yarn guide head body through a rivet.
Description
technical field [0001] The invention belongs to the technical field of a driving device for a yarn guide head of a thread adjuster in a seamless underwear machine, and in particular relates to a piezoelectric actuated yarn guide head. Background technique [0002] The yarn guide head commonly used in the existing underwear machine thread regulator adopts pneumatic drive, and the yarn guide head is driven to swing by the pneumatic device. However, the air path required for pneumatic drive is complex, and the movement mechanism of the yarn guide head has many and complicated parts, which makes the processing of the parts difficult and high in cost; and the thread regulator itself is not large, and the pneumatic drive method needs to install an additional pneumatic device , which makes the external structure of the thread adjuster complicated, and also requires the processing of complex air passages and sealing devices, which makes the manufacturing and installation inefficient...
