Abstract

The utility model provides an improvement structure of a narrow-web shuttle loom driving mechanism, comprising a shuttle and a gear rack. The utility model is characterized in that a transmission strip moving back and forth is buried in the sley of the traditional shuttle loom; a group of permanent magnetic steel is buried in the relevant position of the transmission strip and the shuttle; a group of magnetic material is also buried in the position of the shuttle bottom, so that the two groups of magnetic material attract each other, with a lay race and the lower warp in between. Thus, when the transmission strip moves, the shuttle on the lay race moves simultaneously along with the transmission strip. The utility model abolishes the conventional art driving mode of gear rack-gear-shuttle, adopts the permanent magnetic steel and the magnetic force driving mode, and brings simple structure and safe operation.

Description

The improvement structure of fly-shuttle loom transmission mechanism in a narrow margin

Technical field

The utility model relates to textile machine, refers to a kind of improvement structure of transmission mechanism of fly-shuttle loom in a narrow margin especially.

Background technology

On fly-shuttle loom in a narrow margin, its traditional drive technology is: the kind of drive of rack and wheel-shuttle all is up and down " shed open " of warp thread because shuttle will back and forth pass, and the transmission device of shuttle must be carried out beyond weaving the zone.Therefore, the shuttle of conventional art all is to adopt mechanical drive mode in the weaving area both sides.As shown in Figure 1, a guide rail 25 is arranged, keeping the horizontal movement position of shuttle 21, establish travelling gear 23 weaving regional A both sides, shuttle 21 bottoms have tooth bar and travelling gear to be meshed; A travelling gear 23 and a beneath long tooth bar 28 of transmission that connects whole slay 26 length are meshed, all gears on the slay of transmission simultaneously 26, therefore, as long as the motion of the long tooth bar 28 of control just can be synchronized with the movement by all shuttles 21 of nationality gear 23 transmissions.

The major defect of conventional art is: shuttle must have enough length, can be simultaneously when making its motion in the middle of the shed open and the travelling gear on both sides mesh simultaneously, just be unlikely to break away from transmission and form " free state ".Woven belt is wide more, and shuttle just certainly will be long more, and this has just influenced the serviceability of machine.

Summary of the invention

The purpose of this utility model is to provide a kind of improvement of transmission mechanism of fly-shuttle loom in a narrow margin, has abolished the kind of drive of the rack and wheel-shuttle of conventional art, has adopted permanent magnetic steel, relies on the kind of drive of magnetic force, has simple in structure, safe and reliable.

The technical solution of the utility model is: in a narrow margin in the slay of fly-shuttle loom, imbed a transmission bar that can move around in tradition.On transmission bar and the corresponding position of shuttle, bury one group of permanent magnetic steel underground; Also bury one group of magnetic material underground in the shuttle bottom, make both be the attraction state, middle interval shuttle race and lower layer warp yarns.

The utility model has the advantages that:

1, adopts permanent magnetic steel to rely on the kind of drive of magnetic force, simplified transmission mechanism, improved machine performance, can reduce machine cost.

2, shuttle length is not restricted by belt width, can shorten shuttle length as far as possible.

3, under the situation of same belt width and same machine-wide, can increase woven belt radical simultaneously, enhance productivity.

4, because shuttle length and motion traverse are little, can improve machine speed.

The specific embodiment

See also shown in Fig. 4,5,6, in a narrow margin in the slay 3 of fly-shuttle loom, imbed " a transmission bar " 2 that can move around in tradition.On " transmission bar " 2 and shuttle 1 corresponding position, bury one group of permanent magnetic steel 5 underground; Also bury one group of magnetic material 4 underground in the shuttle bottom, make both be the attraction state, middle interval shuttle race 11 and lower layer warp yarns 6.Like this, when 2 motions of transmission bar, the shuttle 1 on the shuttle race 11, just and then transmission bar 2 is synchronized with the movement, as long as the motion of control transmission bar 2 just can make shuttle move back and forth in shed open.

Claims

1, a kind of improvement structure of the transmission mechanism of fly-shuttle loom in a narrow margin comprises shuttle, tooth bar, it is characterized in that:

In the slay of fly-shuttle loom in a narrow margin, imbed a transmission bar that can move around, on transmission bar and the corresponding position of shuttle, bury one group of permanent magnetic steel underground;

On corresponding position, shuttle bottom, also bury one group of magnetic material underground, make both be the attraction state, middle interval shuttle race and lower layer warp yarns.
