Loom heald frame provided with transverse moving mechanism

Abstract

A loom heald frame provided with a transverse moving mechanism is characterized in that a reinforcing plate (11) is arranged between an upper cross beam (2) and a lower cross beam (12), wherein a plurality of sliding block guide rails (1) are arranged in parallel on the upper cross beam (2); a plurality of sliding blocks (3) which are arranged at intervals are assembled to the sliding block guiderails (1) and are connected through sliding block connecting plates (4); a plurality of motor mounting seats (9) are mounted at the outer edges of the right end parts of the sliding block guide rails(1); a driving motor (10) is mounted in the motor mounting seat (9) and is connected to connecting blocks (6) at the right end parts of the sliding block connecting plates (4) through elastic couplings (8) and connecting screws (7). When the loom heald frame is at an upper opening position, the driving motor (10) is controlled through an electric control system to drive the sliding block connecting plates (4) to drive the sliding blocks (3) to randomly transversely move within 80mm according to the preset program of a computer; yarn driving needle bars mounted on the sliding block connecting plates (4) can drive yarns to realize twisting in a manner that a warp crosses one or a plurality of warps, thus achieving the spinning of a special fabric.

Description

technical field [0001] The invention relates to textile machinery, in particular to a heald frame device of a loom. Background technique [0002] A loom is a mechanical device that processes textile raw materials such as thread and silk into silk threads and then weaves them into cloth. The heald frame is an important part of the loom. The existing heald frame is a rectangular frame structure with guide plates and hangers on both sides. There are several metal healds in the middle of the frame, which are densely connected side by side between the upper and lower beams. At present, the existing domestic heald frames are driven by the dobby of the loom, and can only reciprocate up and down in the guide groove of the loom. It is impossible to realize the twisting action of one warp yarn spanning multiple warp yarns, which is limited and cannot be used for weaving special fabrics. For fabrics with various special requirements, weaving requirements cannot be met. Contents of t...
