Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model air-jet loom step-down solar term mechanism.
Fig. 2 A is the use state diagram of auxiliary nozzle in the utility model air-jet loom step-down solar term mechanism.
Fig. 2 B is the cutaway view of auxiliary nozzle in the utility model air-jet loom step-down solar term mechanism.
The specific embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, Figure 2 shown in A, Fig. 2 B, the air-jet loom step-down solar term mechanism of the utility model embodiment comprises reed 1, and reed 1 is provided with reed groove 2, and reed groove 2 is " U " shape structure, reed groove 2 comprises reed lower lip 21 and reed upper lip 22, and the width K of reed groove 2 is 2 to 6 millimeters, reed lower lip 21 is shorter to the distance of reed groove 2 bottoms than reed upper lip 22 to the distance of reed groove 2 bottoms, reed lower lip 21 is provided with rounded corners away from reed groove 2 bottom land ends, the radius R of rounded corners is 3 to 7 millimeters, the notch place that is positioned at reed groove 2 is provided with auxiliary nozzle 3, auxiliary nozzle 3 is 1 to 3 millimeter to the distance L of reed lower lip 21, the radian of reed lower lip 21 is little, this reed constructions is matched with auxiliary nozzle 3 and uses, make auxiliary nozzle 3 more approach reed groove 2 with suitable angle, approach weft yarn, improve Weft force, reduce auxiliary spray pressure to reach, equally normally perfect weft traction, reach the technique object of wefting insertion, simultaneously, due to auxiliary spray pressure decreased, same injecting time, just reduce the compressed air consumption of wefting insertion.
The puff prot 31 of auxiliary nozzle 3 is pyramidal structure simultaneously, and preferably, the width H of the inlet end of puff prot 31 is 1.4 to 1.9 millimeters, and the width h of outlet side is 1.2 to 1.7 millimeters.The auxiliary nozzle 3 of this special " tapered " interior structure, can make the air-flow boundling of ejection stronger, and just stronger to the tractive force of weft yarn, the flying speed of weft yarn is just faster, thereby can reduce the injecting time of auxiliary spray, and then reaches minimizing compressed air consumption object.
Aborning, the weft insertion system of air-jet loom is by gas source purification, air pressure adjustment or gas flow-regulating, gas circuit, main and auxiliary nozzle 3, special-shaped reed 1, weft accumulator, weft yarn for creel, control the installation composition such as electromagnetic valve 4 of main and auxiliary nozzle 3 air flow switch.Wefting insertion work is mainly completed jointly by main burner, auxiliary nozzle 3 and special-shaped reed 1.Main burner will enter the compressed air of main burner, modulate by technological requirement, accelerate and act on fully weft yarn surface, make weft yarn from the static required flight initial velocity of wefting insertion that accelerates to, weft yarn is transported in special-shaped reed 1 groove and determines that weft yarn correctly enters angle and the position in special-shaped reed 1 groove.3, auxiliary nozzle sprayed before weft yarn arrives, and drove weft yarn front air movement, reduced the resistance of air to weft yarn; Make weft yarn front end produce relative negative pressure, weft yarn is had to sucking action; Supplement the energy of main jet air-flow, weft traction, makes weft tracting flow keep certain speed simultaneously, send shed open in the mode of relay by weft yarn; Overcome weft yarn gravity, make it the position flight on the upper side at reed groove 2 centers.Main burner and auxiliary nozzle 3 cooperatively interact and weft yarn traction is passed through to fell complete wefting insertion.
The main burner of air-jet loom, auxiliary nozzle 3, shear the effect difference because of jet-stream wind such as spray, normal spray, drawing-off spray, to the requirement of air pressure height also difference just.In the time running well, in many multi-jet consumption gas, auxiliary nozzle 3 air consumptions account for 70% left and right of whole air consumptions, so consider the main auxiliary spray consumption gas that reduces from solar term.
To sum up, reed lower lip 21 of the present utility model is shorter to the distance of reed groove 2 bottoms than reed upper lip 22 to the distance of reed groove 2 bottoms, be positioned at reed groove 2 places and be provided with auxiliary nozzle 3, auxiliary nozzle 3 is 1 to 3 millimeter to the distance L of reed lower lip 21, the puff prot 31 of auxiliary nozzle 3 adopts pyramidal structure simultaneously, by to reed 1 appearance structure, auxiliary nozzle 3 is transformed, not only can reduce the use amount of unit interval compressed air, cut the waste, and under less atmospheric pressure state, do not affect weft yarn and fly proterties condition, guarantee that weft yarn correctly arrives, reduce the bad fault producing in weaving process, weave high-quality electronic glass cloth.
The above is the specific embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some modifications, these are revised and are also considered as protection domain of the present utility model.
