Abstract
The invention discloses a master nozzle structure of a jet-type textile machine. The master nozzle structure comprises a nozzle body, a tapered sleeve, a nozzle core and a yarn guiding tube which are arranged inside the nozzle body. The yarn guiding tube comprises a fixedly-connected fixing end and an adjusting end. The yarn guiding tube are formed by two segments, so that the size of the fixing end is processed and manufactured according to the largest diameter of a jet-type textile machine; and the diameter of the adjusting end can be adjusted by rotating a driving screw according to different types of the yarn, so that the size of a gap at the throat portion of the master nozzle is adjusted to meet the requirements of textile production. The process step of turning down the machine to change the master nozzle in working can be omitted, labor and raw materials are reduced, working efficiency is improved; and meanwhile, when yarns with small twist are adopted, air flow rate is constant, and the gap of the master nozzle can be accordingly increased by reducing the diameter of the adjustable end, so that jet flow speed is reduced, and energy is saved.

Determine design guide rail and the spacing that drives screw according to the precision requirement regulating, by securing member, guide rail is fixed together with driving screw engagement.
According to the twist size of weft yarn, can be by regulating and drive screw with screwdriver clockwise or counterclockwise.According to pitch size, pitch p of every driving can make yarn-guide tube left end size expand or dwindle p/2 π.
In the time that loom is normally worked, Q is certain for its gas pushing quantity, in theory Q=interval area S air velocity V; Therefore in the time using the less yarn of the twist; existing loom need to be shut down the main burner of the wefting insertion runner of changing minor diameter; and main burner structure disclosed by the invention only need to be according to the driving screw that regulates clockwise left end; the corresponding increase in main burner gap simultaneously; thereby reduce weft tracting flow speed, reduced energy consumption.Therefore, the practical application of this technology and device can change integral structure and the function of existing loom; And can save comprehensive materials and the comprehensive cost of existing loom, cost is lower.
After yarn-guide tube 4 is arranged on nozzle body 1, its total length is identical with same model nozzle core total length, and main is like this to make this main burner structure and existing loom have matching, improves versatility of the present invention.
On adjustable side, be connected with air-flow guide plate 46, air-flow guide plate 46 is fixed with guide rail 42 one.Can change along with the change in size of guide rail.Nozzle body 1 inner side and air-flow guide plate 46 corresponding positions offer locating slot 47, and locating slot 47 is cannelure, and the diameter of locating slot 47 is consistent with the adjustable maximum gauge of air-flow guide plate 46.By being set, locating slot is convenient to yarn-guide tube to carry out effective location.
Air-flow guide plate 46 rib portions are rounded down, thereby prevent from guiding cross section, flow field in air-flow process to occur that sudden change causes turbulent flow, affects the traction of weft yarn.
On nozzle body 1, offer adjustment hole 11, the vertical yarn-guide tube 4 of adjustment hole 11 arranges, and adjusting rod (as shown in figure 10) is installed in adjustment hole 11, in order to drive nozzle body 1 internal drive screw 41 to rotate.
Adjusting rod comprises magnetization bar 12, is positioned at the gear 13 and adjustment cap 14 of magnetization bar 12 one end, and the other end of magnetization bar 12 is provided with draw-in groove 15, and draw-in groove 15 matches with the end that drives screw 41.Magnetization bar 12 can be from nozzle body 1 adjustment hole insert, draw-in groove is magnetized, can with the material tight adhesive of driving screw that is cast iron; Gear 13 and adjustment cap 14 are plastic products, and are cast into one; Main burner 1 outside is also provided with gear counter (not shown), and gear counter is connected with gear.The parameters such as the pitch of the driving screw of this gear counter intrinsic parameter and yarn-guide tube match; Yarn-guide tube be can be adjusted to maximum gauge time scale mark zeroing, when rotation adjustment cap 14, be every when driving screw is turned over to a pitch, gear counter can the certain numerical value of corresponding increase, can regulate main burner according to the data on gear counter.
Driving screw material is cast iron.Hardness intensity is higher, and brace rod is stainless steel, has guaranteed intensity and stability that stiff end is right.
An assembly method for Puffer type weaving loom main burner, concrete steps are as follows:
One, yarn-guide tube 4 is inserted in nozzle body 1 from the left end of nozzle body 1, and it is interior fixing to make air-flow guide plate 46 be installed on locating slot 47;
Two, adjusting rod is inserted in adjustment hole 11, draw-in groove 15 mates with the end clamping that drives screw 41, because magneticaction makes magnetic rod 12 and drives the tight adhesive of screw 41;
Three, after, successively taper sheath 2, nozzle core 3 are packed into nozzle body 1 interior fixing;
Four, the scale mark of gear counter zeroing while adjustable side being adjusted to maximum gauge, rotation adjustment cap 14, magnetization bar 12 drives and drives screw 41 to rotate, drive pitch of the every rotation of screw 41, gear counter i.e. a numerical value of corresponding increase, regulates main burner according to the data on gear counter.
The invention discloses a kind of main burner structure and assembly method of Puffer type weaving loom, by yarn-guide tube is composed of a fixed connection by stiff end and adjustable side, the size of stiff end is according to the greatest diametrical dimension processing and manufacturing of air-jet loom, adjustable side can be according to the difference of yarn model, by rotariling actuate screw to adjust the diameter dimension of adjustable side, thereby regulate nozzle throat gap length to meet weaving need of production, be applicable to the user demand of different model yarn, in work, remove from and shut down the processing step of changing main burner, reduce artificial and raw-material cost, enhance productivity, simultaneously, while using the less yarn of the twist, in the situation that gas pushing quantity is certain, make the corresponding increase in gap of main burner by dwindling the diameter dimension of adjustable side, thereby reduce jet flow velocity, to save energy consumption.
