Abstract

The present invention relates to a sley of a magnetic control shuttle loom. A shuttle path is covered by a long thin plate so as to prevent impurities from entering the shuttle path. In addition, magnets in a shuttle conducting body are close to magnets in a shuttle, which provides magnetic attraction force required when wefts are picked.

Description

Magnetically-controlled slay of shuttle loom

The present invention relates to a kind of magnetically-controlled slay of shuttle loom, especially a kind of slay that prevents that foreign material from invading.

See also Fig. 1, Fig. 1 is the stereogram of the magnetically-controlled slay of shuttle loom of prior art, Fig. 2 is the cutaway view of prior art magnetically-controlled slay of shuttle loom, and slay 1 comprises a slay body 11, one reed 12, and a pair of separator 13, wherein, this slay body 11 is microscler ducted body, and reed 12 is arranged on slay body 11 1 sides, this reed 12 has several parallel steel wires 121, and last warp thread 35 and following warp thread 34 can be by passing through between the steel wire 121.This is individually fixed in both sides on these slay body 11 end faces to separator 13, and this is to several grooves 132 are arranged between the shim 131 on the separator 13, can pass through for warp thread 34 down.One shuttle 24 is placed on slay 1 end face, and supported by separator 13, one second magnet 241 is arranged in the shuttle 24, one shuttle body 23 is arranged at reciprocating motion in the slay body 11, fix one first magnet 231 in the shuttle body 23, make shuttle 24 carry out picking at

last warp thread

35 and 34 on following warp thread in order to attract above-mentioned second magnet 241.

When weaving cotton cloth because shuttle 24 needs reciprocating motions constantly, adding shuttle 24 speed is exceedingly fast, under speed sharply changes, shuttle 24 normal disengaging magnetic force are controlled and are flown out, can correctly control moving of shuttle 24 in order to ensure shuttle body 23, how increase therefore that magnetic attraction is crucial problem between above-mentioned first and second magnet 231,241 always.

Chinese patent once proposed a kind of improved slay No. 24029, see also Fig. 3, Fig. 3 is the slay cutaway view of this patent, wherein, on slay body 31, offer a race 311, and allow shuttle body 23 stretch in the race 311, make the distance of first magnet 231 and second magnet 241 more approaching, because magnet suction size is inversely proportional to the cube of distance, therefore, the not enough problem of above-mentioned magnetic attraction achieves a solution, yet this patent but runs into another problem on the implementation, owing to set out a race on the slay body 31, therefore foreign object is (as instrument, screw etc.) just have an opportunity to enter in this slay body 31, when especially weaving short fiber, a large amount of easier long-pending plugs in slay body 31 of silk floss bits brought puzzlement to plant produced.

The object of the present invention is to provide a kind of improved magnetically-controlled slay of shuttle loom, it can prevent foreign material intrusion slay.

The object of the present invention is achieved like this, promptly by a kind of magnetically-controlled slay of shuttle loom, ccontaining one shuttle body with first magnet in it, Magnetic force tracting by this shuttle body first magnet, can make shuttle band one weft yarn with second magnet between several warp thread, carry out picking, this slay comprises: a slay body, and this slay body is microscler ducted body, offers a race along its longitudinally; One reed is arranged at this slay body one side, and this reed has several parallel steel wires, and above-mentioned warp thread is by passing through between above-mentioned steel wire; A pair of separator, this is microscler to separator and is individually fixed on this slay body of these race both sides that this has several shims to separator, and forms several grooves between above-mentioned shim, puts above-mentioned warp thread with the Tibetan; And a microscler thin plate, be located on the above-mentioned separator, in order to above-mentioned race is covered.

The invention has the advantages that it has microscler thin plate race is covered, can prevent that foreign material from invading in the race, shuttle body and shuttle internal magnet are quite approaching, required magnetic attraction when picking is provided.

Below in conjunction with accompanying drawing, embodiments of the invention are described, wherein:

Fig. 1 is the stereogram of prior art magnetically-controlled slay of shuttle loom;

Fig. 2 is the cutaway view of prior art magnetically-controlled slay of shuttle loom;

Fig. 3 is the cutaway view of No. 24029 slay of Chinese patent of prior art;

Fig. 4 is the cutaway view of first embodiment of the invention magnetically-controlled slay of shuttle loom;

Fig. 7 is the microscler thin plate stereogram of second embodiment of the invention magnetically-controlled slay of shuttle loom.

See also Fig. 4, Fig. 4 is the cutaway view of first embodiment of the invention magnetically-controlled slay of shuttle loom, wherein, slay body 61 is microscler, offers a race 311 along its longitudinally, and reed 12 is fixed in a side of this slay body 61, one microscler thin plate 5 is fixed on this slay body 61 and with race 311 and covers, please consult Fig. 5 simultaneously, Fig. 5 is the stereogram of this microscler thin plate among Fig. 4, and this microscler thin plate 5 comprises a recess 51; And two linking part 52, this linking part 52 is positioned at recess 51 both sides and integrally formed with recess 51, and this microscler thin plate 5 is fixed on the slay body 61 by this linking part 52, a pair of microscler separator 13, be fixed in by screw 33 on the slay body 61 of race both sides, and this deposits warp thread 34 to offering several grooves on the separator 13, can hiding.

Shuttle 24 with weft yarn places on the end face of slay, and supported by separator 13, one second magnet 241 is arranged in the shuttle 24, shuttle body 23 is arranged in the slay body 61 and reciprocating motion, set firmly one first magnet 231 in the shuttle body 23, carry out picking in order to attract above-mentioned second magnet 241 to drive shuttle 24, can find out significantly by Fig. 4, though microscler thin plate 5 covers race (preventing the foreign material intrusion), but its recess 51 still can hold shuttle body 23 to be stretched into, therefore distance is not elongated significantly between first magnet 231 and second magnet 241, and required magnetic force still can provide.

See also Fig. 6, Fig. 6 is the cutaway view of second embodiment of the invention magnetically-controlled slay of shuttle loom, wherein, race 311 is covered by microscler thin plate 7, please consults Fig. 7 simultaneously, Fig. 7 is the stereogram of this microscler thin plate among Fig. 6, this microscler thin plate 7 is respectively offered a row of openings 71 along the longitudinally both sides, in order to the shim 131 on the ccontaining separator 13, because the shape and separator 13 complementations of microscler thin plate 7, therefore can driving fit when microscler thin plate 7 being locked in separator 13, invade race 311 to prevent flocking etc.
