Description
Technical field
The present invention relates to a kind of composition mechanism of air-jet loom, be specifically related to a kind of air inlet curl and the continuously adjustable main nozzle of jet loom of charge flow rate, belong to technical field of textile machine.
Background technology
In textile weaving process, textiles there will be broken string or the too much situation of surface spikes, this just have impact on overall appearance degree and the mechanical characteristic of fabric, and this mainly yarn continuous contact friction in fabrication processes, when yarn mechanics characteristic reduces, make yarn backtwisting to such an extent as to fracture.And this greatly reason be because parallel is when wefting insertion, due to the effect of air-flow, parallel is proal while, and the backtwisting self yet occurred, this does not plan a successor with regard to the situation making parallel and bear pulling force or friction, and burr.
Increasingly extensive along with textile application in recent years, also it is also proposed higher requirement to the mechanical characteristic of fabric and aesthetics.Due in weaving process after completing wefting insertion action, parallel two ends are in and freely relax, beat up in process what close along with fell, parallel produces stress to balance the active force of warp thread, the parallel part mediated due to both sides warp thread numerous, so more difficult contraction, therefore its internal stress is larger, although the elasticity of weft yarn is larger compared with warp thread, if parallel is when in wefting insertion process, airflow field curl is larger, when sth. made by twisting is to time inconsistent with curl, weft yarn just there will be backtwisting, just breakage of weft may be caused when beating up, this just makes to weave and cannot complete smoothly.
Therefore, in order to avoid in weaving process because of parallel backtwisting, cause fabric mechanics property difference, be necessary to design a kind of air inlet curl and the continuously adjustable main nozzle of jet loom of charge flow rate, to overcome the different qualities due to yarn, cause yarn backtwisting in airflow field.
Summary of the invention
For solving the problems of the technologies described above, the first object of the present invention is to provide that a kind of structure is simple, weft yarn not easy fracture and stable air inlet curl and the continuously adjustable main nozzle of jet loom of charge flow rate.
The second object of the present invention is the control method providing a kind of air inlet curl and the continuously adjustable main nozzle of jet loom of charge flow rate.

Air inlet curl of the present invention and the continuously adjustable main nozzle of jet loom of charge flow rate are set to further: described nozzle fuse is provided with 4 air inlet runners.
Air inlet curl of the present invention and the continuously adjustable main nozzle of jet loom of charge flow rate are also set to: in described inlet channel, be provided with an air inlet electromagnetic valve, and this air inlet electromagnetic valve, positioning motor, scheduling motor are connected on a control unit respectively.
For realizing above-mentioned second object, the technical solution used in the present invention is: a kind of control method adopting air inlet curl and the continuously adjustable main nozzle of jet loom of charge flow rate, it comprises the steps: 1), by the sth. made by twisting of yarn to being input in control unit with yarn speciality, generate the relevant configured parameter of scheduling motor, positioning motor and air inlet electromagnetic valve, by communication bus, signal transmission, to all parts, produces the stream condition adapted; 2), carry out yarn wefting insertion afterwards, treat that weft yarn arrives nozzle body exit, by thread grip, by the motion conditions of high-speed camera instrument observation yarn; 3), if yarn still presents instability, continue the manually above-mentioned regulating parameter of adjustment, make yarn motion state reach ideal effect.
Compared with prior art, the present invention has following beneficial effect: air inlet curl of the present invention and the continuously adjustable main nozzle of jet loom of charge flow rate pass through the combination of mechanical structure, motor and control unit, form a kind of mechanical-electric coupling control system, effective wefting insertion can be carried out to the yarn of different performance, make the mechanical characteristic that yarn keeps good in airflow field, from but make fabric can show better mechanical characteristic.
