The specific embodiment
The pneumatic tuck-in selvage of this cord fabric Rapier looms mechanism, it comprises air pump and running part, the left side folds into part and the right side folds into part.
Shown in Fig. 1-2.Power transmission shaft 11 is supported on the bearing block 14 that is positioned at air pump holder 12 in described air pump 16 and the running part, power transmission shaft 11 1 ends are fixed with synchronizing jugged belt wheel, the other end is fixed with two gear I13 arranged side by side, described gear I13 meshes with the gear II15 that is fixed on air pump bent axle 18 ends respectively, is respectively equipped with the last bend pipe 113 that is communicated with left and right spray suction nozzle 26,36 sealings on the cylinder cap 112 of described air pump 16.
This part working method is: by synchronizing jugged belt wheel rotatablely moving of loom final drive shaft passed to power transmission shaft 11 synchronously by synchronous cog belt, two gear I13 are housed on the power transmission shaft drive gear II15 on left and right two air pumps respectively.The pump housing 17 and transmission shafts bearing 14 are fixed on the air pump holder 12, and the air pump holder then is fixed on the base of loom.Power is passed to bent axle 18 by the air pump gear, bent axle drivening rod 19, and connecting rod drives piston 110, piston reciprocating motion in cylinder body 111, inner chamber of cylinder block and main shaft form positive negative pressure synchronously, and bend pipe 113 is received left and right spray suction nozzle respectively by the highstrenghtpiston on the cylinder cap 112, and it is air-breathing to form expiration synchronously.Other structure time of this part and loom cooperates easy to adjust and shedding mechanism combines cleverly.
Shown in Fig. 5-7.Described right side folds into the part overall fixed on scissors installing plate 314 and scissors shaft 313, and scissors is fixed on fixed blade 311 on the right scissors holder 31 by the fixedly support arm 39 that cooperatively interacts, and the movable scissors 310 that is installed on the scissors rocking arm 35 is formed; Weft cutter cam 33 be locked at the synchronous operated scissors shaft 313 of loom main shaft on, the scissors rocking arm that the middle part is provided with fulcrum makes its upper roller 32 contact with cam 33 by extension spring 34 tensions, suction nozzle 38 is fixed on the right scissors holder, and it is communicated with the refuse yarn recycling bin by bend pipe 37, corrugated tube.Right spray suction nozzle 36 places are provided with the tube connector 312 that is connected with air pump.
Right folding is gone into the part working method: this mechanism's overall fixed can be adjusted reed width width easily on scissors installing plate 314 and scissors shaft 313.Scissors is divided into fixed blade 311 and movable scissors 310, and fixed blade is fixed on the right scissors holder 31 by fixing support arm 39, and its height remains unchanged when loom turns round after all around adjust according to fabric-fell the position.Movable scissors is installed on the scissors rocking arm 35, and the position that can adjust itself and movable scissors easily reaches desirable shear effect.Weft cutter cam 33 is locked on the scissors shaft 313, scissors shaft and loom main shaft run-in synchronism, and other synchronized movement of scissor cut and loom and time are easy to adjust.Rocking arm makes its upper roller near cam by the extension spring tension, and the cam rotating band shakes arm swing, and movable scissors 310 rotary oscillations form shearing motion with fixed blade.The suction nozzle 38 that is fixed on right scissors holder is received the refuse yarn recycling bin by bend pipe, corrugated tube, will seal the refuse yarn recycling bin by the Cyclone wind motor of strengthening (0.75KW) and form negative pressure, has formed the very strong air-flow of inhaling inwards like this at the suction nozzle place.
When connecing latitude pincers latitude device release weft yarn, suction nozzle 38 holds weft yarn tail head and keeps certain force of strain, when reed with weft yarn when loom the place ahead pushes away, warp thread is remained silent, at this moment scissors is open, after weft yarn enters the scissors mouth, the movable scissors closure, weft yarn is cut off, the refuse yarn of cutting is drawn onto collection box, by new weft yarn tail head in the fell of cutting off is then being sucked by right side spray suction nozzle 36 of fixed length, and when loom ran to next fell opening, spray suction nozzle in right side was blown into fell with weft end and forms the tuck-in selvage plain edge.
As shown in Figure 3-4.Described left side folds into part and has adopted active type filling cutter mechanism and left side spray suction nozzle 26, colluded yarn plate 24, left side spray suction nozzle installing plate is fixed on the scissors installing plate 27, on left side spray suction nozzle installing plate 21, be provided with fixed axis 22, movable left side spray suction nozzle is housed on this fixed axis, colludes the yarn plate and be fastened on the fixed axis by adjusting piece 23;
This part has reasonably been used active type filling cutter of the prior art mechanism, and special purpose parts is reduced.Only newly designed left spray suction nozzle and colluded yarn feeding device, designs simplification.Pump nozzle head installing plate be fixed on scissors installing plate on the same with the right side in a left side can be adjusted reed width width easily.The fixed axis that is fixed on the installing plate is equipped with left side spray suction nozzle, and the position of left side spray suction nozzle can rotate adjustment up and down all around to guarantee to reach desirable position.Spray suction nozzle in a left side connects air pump by High strength plastic pipe 25.Colluding the yarn plate is fastened on the fixed axis by adjusting piece.
After sending latitude pincers latitude device to bring weft yarn into the active type filling cutter, scissors will collude the weft yarn in the yarn plate outside and cut off, spray suction nozzle in a left side sucks the outer weft yarn loose thread of selvedge, and before the loom fell was remained silent, left side spray suction nozzle was blown into fell with the weft yarn loose thread, after the fell closure, the weft yarn that reed will just have been introduced pushes away and will fold into the weft yarn end forward and clamps, and simultaneously this root weft yarn is colluded the yarn plate and catches on, rest on scissors in face of, when sending latitude pincers latitude device to bring weft yarn into the active type filling cutter once more, begin the circulation of next latitude.
