Description
Technical field
The present invention relates to a kind of crochet hook swing mechanism on knot fishing net machine that has, belong to aquatic products articles for use technical field.
Background technology
Reticulated is divided into be had junction type and without junction type, is applicable to respectively different use occasions.If claimed structure is more stable, as net, used for aquiculture net cage etc. for fishing, general use has junction type reticulated.In architectural engineering with safety net, other occasion with sunshade net etc., generally adopt knotless net shape fabric.Knotless net shape fabric generally weaves by few guide bar warp knitting machine, has knot reticulated general using to have knot fishing net machine to weave.In order to realize, be woven with knot reticulated, in having junction type fishing net machine, the motion of upper crochet hook is the nucleus movement of complete machine, and its effect is that knitmesh warp is tied a knot.For upper crochet hook, its motion comprises the requirement of forms of motion and big or small two aspects of motion.On forms of motion, in requirement, crochet hook is done the oscillating motion around fixed point; Motion size comprises again two aspects, the one, and the size of pendulum angle amplitude, the 2nd, the Changing Pattern requirement of moving displacement in swing process, pendulum angle amplitude size can realize by linkage or cam mechanism.And the needle movement of rising to the bait of prior art adopts general linkage more single to warp knotting, simultaneously often because upper crochet hook swings not in place or moving displacement amount is inadequate, thereby the needle movement that causes rising to the bait does not carry out easily causing in knotting process knotting firm or can not effectively complete knotting to warp, make the fishing net born second-rate, must carry out the reparation of fishing net anastomose, thereby strengthened operator's labour intensity, reduced the operating efficiency of complete machine.
Summary of the invention
