Technical Field
The utility model relates to a hydraulic loom especially relates to a hydraulic loom of hank mode.
Background
The loom mainly forms fabric by interlacing warp yarns and weft yarns through operations such as opening, weft insertion, beating-up, reeling-up, warp let-off and the like, and different fabrics have different warp and weft interlacing laws. The opening operation is generally performed by: the warps pass through the through holes in the middle of the heddles respectively and are divided into an upper layer and a lower layer along with the up-and-down movement of the heddles to form a space channel for the weft insertion device to pass through, namely a shed. Most of the shedding mechanisms of the existing water-jet looms are that warp yarns form a shed every time a main shaft of the loom rotates for one circle, and the requirement of high-speed twirling shedding cannot be met.
In addition, most of the existing water-jet looms weave silk screens by adopting a weaving method of a conventional fabric, and the weaving method can not enable warp yarns to be wound in the process of forming a shed by the warp yarns, so that twisting weaving can not be realized, and the woven silk screen fabric has low quality and poor strength. At present, a very small number of water-jet looms can realize the twisting weaving in the process of forming a shed by warps, but the opening twisting weaving mechanism used by the water-jet loom is unreasonable, and mainly has defects in the aspect of a power mechanism, namely, the transverse reciprocating movement of a twisting heald reed in a heald frame is completed by the cooperation of a longitudinally moving cam and a return spring, the structure of the water-jet loom is complex, and the operation is not stable enough. Patent CN202247138U discloses an open-end leno weaving mechanism for a plastic mesh weaving machine, which comprises a heald frame capable of longitudinally reciprocating, and a leno heddle reed arranged in the heald frame and capable of transversely reciprocating, wherein the leno heddle reed is provided with a leno weaving power mechanism; the leno weaving power mechanism comprises a cam mechanism and a corresponding rocker connecting rod assembly, and the cam mechanism drives the leno heddle reed to transversely reciprocate through the rocker connecting rod assembly; above-mentioned rocker link assembly includes vertical rocker, L shape rocker and the rocker that falls L shape, the lower extreme of vertical rocker is provided with the articulated shaft, the top of vertical rocker is firstly articulated with the leno heddle reed, secondly be connected through the connecting rod with the pole setting section of L shape rocker, the apex angle department of L shape rocker is provided with the articulated shaft, the horizontal pole section of L shape rocker is articulated with the horizontal pole section of the rocker that falls L shape, the apex angle department of the rocker that falls L shape is provided with the articulated shaft, the pole setting section of the rocker that falls L shape passes through the cam connecting rod and is connected with the cam among the cam mechanism. This patent passes through cam mechanism and rocker link assembly and drives the horizontal reciprocating motion of leno heddle reed, can arouse great impact and vibration because of the clearance at high-speed moving in-process, and in the long term, can bring great impact and vibration wearing and tearing to cam mechanism especially rocker link assembly to the life of equipment has been reduced, has increased the manufacturing cost of enterprise.
