The invention discloses a harness wire-free jacquard head, belongs to parts for
textile machinery, and in particular to the technical field of design and manufacture of the harness wire-free jacquard head. A driving motor is arranged on the front part of a
body frame; hook piece slideway linkage mechanisms are arranged on two sides of the
body frame; an upper piezoelectric
ceramic piece is arranged on a hook piece middle slideway; a lower piezoelectric
ceramic piece is arranged on a hook piece lower slideway; during weaving, a
toothed belt is driven through the driving motor to rotate an eccentric block, so that a hook piece middle slideway
moving frame is driven to reciprocate up and down in a reciprocating way between a hook piece upper slideway fixing frame and a hook piece lower slideway fixing frame, the
retention time sequence of the upper and lower positions of the hook piece is controlled by utilizing the deformation of the piezoelectric
ceramic piece, and the
retention time sequence of the upper and lower positions of the
electromagnet-controlled warp yarns is replaced. The piezoelectric ceramic piece is small in size, low in
power consumption, stable and reliable, the performance is far superior to that of the
electromagnet, the stability of the
machine is improved, and the harness wire-free jacquard head is energy-saving and environment-friendly. The harness wire-free jacquard head is mounted on the lowest part of a
textile machine, so that the harness wire-free jacquard head is convenient to
mount and maintain and does not occupy large space; and moreover, the problems in the conventional products are solved.
