Abstract

nullThis utility model provides a kind of slip location formula to catch latitude device，Including the shaped as frame track being arranged on loom and catching latitude end，It is provided with shaped as frame optical sensor on rear side of described shaped as frame track，Four chutes it are provided with inside described shaped as frame track，Two it are provided with by motor-driven slide block in every chute，Slide block in the chute being oppositely arranged is connected by two parallel tinsel correspondences，Described motor and slide block are electrically connected with described shaped as frame optical sensor，Described tinsel is driven rotation and direction of rotation contrary by motor，In this utility model，When shaped as frame optical sensor detects after weft yarn passes，Electric motor starting，Slide block drives parallel tinsel from the quick move toward one another in shaped as frame track limit，The tetragon surrounded due to four parallel tinsels is more and more less，Finally weft yarn is limited to the center of shaped as frame track，Simultaneously，Owing to tinsel parallel to each other is inwardly to rotation，Weft yarn can be strained，Prevent it from coming off.

Description

A kind of slip location formula catches latitude device

Technical field

This utility model relates to field of textile machinery, especially, is that a kind of slip location formula being applicable to shuttleless loom is caught Latitude device.

Background technology

Fly-shuttle loom is that employing is traditional because of loom.Shuttle volume is big, heavy, is come and gone and repeatedly projects, and machine shakes Dynamic big, noise high, speed is slow, efficiency is low.

And during shuttleless loom after fly-shuttle loom, a kind of new loom of birth.Shuttleless loom is light with its component, vibration Little, noise is low, speed is fast, efficiency advantages of higher, has captured rapidly loom market.Shuttleless loom divides again rapier loom, sheet tatting Machine, water-jet loom, air-jet loom etc., wherein the operation principle of air-jet loom is to use air as because of medium, to eject Compressed air stream to weft yarn produce matcha pull strength draw, weft tapes is crossed shed open, the jet produced by jet is reached To the purpose of succinct wefting insertion, owing to the medium such as water or air driving weft yarn is understood by external influence in flight course, Therefore weft yarn position through catching latitude end every time is different from, and causes weft yarn to be easily separated from weft catching device.

Utility model content

In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of slip location formula to catch latitude device, this slip Location formula catches latitude device can accurately catch weft yarn.

This utility model solves its technical problem and be the technical scheme is that

This slip location formula catches latitude device, including being arranged on loom and catch the shaped as frame track of latitude end, arranges after described shaped as frame track There is shaped as frame optical sensor, inside described shaped as frame track, be provided with four chutes, be provided with two in every chute and driven by motor Dynamic slide block, the slide block in the chute being oppositely arranged is connected by two parallel tinsel correspondences, described motor and slide block with Described shaped as frame optical sensor is electrically connected, and described tinsel is driven rotation and direction of rotation contrary by motor.

As preferably, between the tinsel intersected vertically, air line distance is more than 0.1mm.

As preferably, described centre wiry has the ring-shaped groove matched with weft yarn, makees frosted in its groove Process.

As preferably, the radian of the arc section of described ring-shaped groove is not less than 30 °.

The utility model has the advantage of:

When shaped as frame optical sensor detects after weft yarn passes, and electric motor starting, slide block drives parallel tinsel from shaped as frame The quick move toward one another in track limit, the tetragon surrounded due to four parallel tinsels is more and more less, is finally limited to by weft yarn The center of shaped as frame track, simultaneously as tinsel parallel to each other is inwardly to rotation, can strain weft yarn, prevent it from coming off.

Detailed description of the invention

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:

In the present embodiment, refering to Fig. 1, Fig. 2, Fig. 4 and Fig. 5, this slip location formula is caught latitude device and is included that being arranged on loom catches The shaped as frame track 200 of latitude end, is provided with shaped as frame optical sensor 300, in described shaped as frame track 200 after described shaped as frame track 200 Side is provided with four chutes 220, is provided with two by motor-driven slide block 210, the chute being oppositely arranged in every chute 220 Slide block 210 in 220 connects by two parallel tinsels 100 are corresponding, described motor and slide block 210 and described shaped as frame optics Induction apparatus 300 is electrically connected, and described tinsel 100 is driven rotation and direction of rotation contrary by motor.

Above-mentioned slip location formula catches latitude device, and between the tinsel 100 intersected vertically, air line distance is more than 0.1mm, prevents Square crossing produces abrasion.

Above-mentioned slip location formula catches latitude device, and the centre of described tinsel 100 has the ring matched with weft yarn 10 Shape groove 50, makees frosted and processes, increase the friction of tinsel 100 and weft yarn 10, prevent sluff-offs in its groove.

Above-mentioned slip location formula catches latitude device, and the radian of the arc section of described ring-shaped groove 50 is not less than 30 °.

Above-mentioned slip location formula catches the working method of latitude device:

Refering to Fig. 2 and Fig. 4, when shaped as frame optical sensor 300 detects after weft yarn 10 passes, and electric motor starting, slide block 210 carries Dynamic parallel tinsel 100 from the quick move toward one another in shaped as frame track 200 limit, due to four parallel tinsels 100 surround four Limit shape is more and more less, and weft yarn 10 is finally limited to the center of shaped as frame track, simultaneously as tinsel 100 parallel to each other to Interior to rotation, weft yarn 10 can be strained, prevent it from coming off.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model Protect scope.
