Abstract

The invention discloses a positive warp loosening device of a water jet loom. The positive warp loosening device comprises a left support, a right support, a linkage shaft, a swinging beam and a fixed back beam, wherein the linkage shaft, the swinging beam and the fixed back beam are sequentially arrayed between the left support and the right support from front to back, the linkage shaft is located above the swinging beam, the warp loosening device further comprises only one positive warp loosening mechanism used for driving the linkage shaft to rotate, the positive warp loosening mechanism comprises an eccentric adjusting portion and a warp loosening swinging arm, one end of the warp loosening swinging arm is connected with one end of the linkage shaft, and the other end of the warp loosening swinging arm is connected with the eccentric adjusting portion. The single-side positive warp loosening structure drives the linkage shaft to rotate to drive the swinging beam to swing, and therefore the performance of the whole loom is more reasonable.

Description

technical field

[0001] The invention relates to a water jet loom, in particular to a positive warp loosening device. Background technique

[0002] The function of the warp loosening device of the water jet loom in the whole weaving process is to send out a certain amount of warp yarns with a certain tension in time during the weaving process according to the requirements of the fabric structure on the weft density, so as to maintain the continuous production of weaving. In the weaving process, whether the warp tension is uniform when the weaving beam changes from large to small is the main criterion to measure the performance of the let-off device, and the size and stability of the warp tension depend to a large extent on the amount of loose warp the size of.

[0003] The original water-jet loom loosening device sends out the warp yarn in a negative tension mechanism. Although its structure ensures the rigidity of the tension roller, it cannot solve the problem of difficult...
