Abstract

The utility model provides a latitude ware is caught to rivers formula includes support and water jet, the water jet is fixed on the support, the spout of water jet is the platykurtic just, the water jet below is equipped with a basin, the basin has the woof of confession to pass through in the face of opening on the cell wall of woof incident direction the opening of " V " font of basin, the open -ended bottom of " V " font is equipped with a spring tongs, be provided with optical sensors on the spring tongs, the utility model discloses in the water jet of platykurtic forms " cascade " after going out water because the opening towards the woof direction is " V " font, consequently, when the woof pass " cascade ", by rivers towards the screw clamp and along with rivers during along downwards delivery port motion of cell wall, the woof can slide until its bottom along being " V " font open side down, at this moment, the woof blocks the light that optical sensors sent, the spring tongs starts the woof fixedly, the latitude is caught to the realization accuracy.

Description

A kind of flow type catches latitude device

Technical field

This utility model relates to shuttleless loom field, especially, is the current of a kind of shuttleless loom Formula catches latitude device.

Background technology

Shuttleless loom is widely used in field of textiles with its superior performance, wherein, without tatting Water-jet loom in machine is to use water as wefting insertion medium, with jet water course, weft yarn is produced friction Pull strength, is that the weft yarn on fixed bobbin introduces shed open.

Water-jet loom is the one of shuttleless loom, and the leading portion every time sprayed due to water-jet loom is (i.e. The moment of current ejection spout, the current of its head section, owing to having adhesion with jet wall, cause current The head section convergence of ejection is bad, when guiding weft yarn flight, easily deviates correct track, causes Sluff-offs fault.

Utility model content

In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of flow type to catch latitude Device, this flow type is caught the weft yarn catching the weft yarn correct track of deviation that latitude device can be stable, is completed Accurately catch latitude.

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

This flow type is caught latitude device and is included that support and water jet, described water jet are fixed on support, The spout of described water jet is flat and is connected with a water pump, is provided with one below described water jet Tank, described sink surface has the described water passed through for weft yarn on the cell wall to weft yarn incident direction The opening of " V " font of groove, the bottom of the opening of described " V " font is provided with a spring handgrip, Described bottom of gullet is provided with an outlet, and described spring handgrip is provided with optical sensor, and two Person is electrically connected.

As preferably, the quantity of described water jet is no less than 3 and is parallel to each other.

As preferably, the bottom of described " V "-shaped opening is curved, and its radian is little In 180 °, and the circle at this arc place is onesize with the cross section of weft yarn.

As preferably, the displacement of described outlet is more than the total inflow of described water jet.

As preferably, described bottom of gullet is downward-sloping along the weft yarn direction of motion, at the bottom of described tank Bosom, portion arranges described outlet.

The utility model has the advantage of:

" cascade " is formed, due in the face of the opening of weft direction after the water jet water outlet of flat " V "-shaped, therefore, when weft yarn through " cascade ", be flushed to by current tank and along with Current along cell wall outlet downwards move time, weft yarn can be along " V "-shaped opening Slide downward is until its bottom, and at this moment, weft yarn blocks the light that optical sensor sends, spring Handgrip starts to be fixed weft yarn, it is achieved accurately catch latitude.

Accompanying drawing explanation

Fig. 1 is the structural representation (left view) that this flow type catches latitude device.

Fig. 2 is the profile that this flow type catches the tank of latitude device, support and water jet.

Fig. 3 is the front view that this flow type catches latitude device.

Fig. 4 is the enlarged drawing of I.

Fig. 5 is the relative position view of spring handgrip, optical sensor and weft yarn.

Detailed description of the invention

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

The most in the present embodiment, refering to Fig. 1, Fig. 2, Fig. 3, including support 110 and water spray Mouth 100, described water jet 100 is fixed on support 110, the spout of described water jet 100 It is connected in flat and with a water pump, below described water jet 100, is provided with a tank 200, institute State tank 200 have on the cell wall of weft yarn 10 incident direction for weft yarn 10 pass through described The opening 201 of " V " font of tank 200, the bottom of the opening 201 of described " V " font It is provided with a spring handgrip 300, bottom described tank 200, is provided with an outlet 210, described bullet Optical sensor 301 it is provided with, both electrical connections on spring handgrip 300.

Above-mentioned flow type catches latitude device, and the quantity of described water jet 100 is no less than 3 and mutually Parallel, the weft yarn 10 of high-speed motion can be reduced successively, it is ensured that quickly catch weft yarn 10.

Above-mentioned flow type catches latitude device, and the bottom of described " V "-shaped opening 201 is arc Shape, its radian is not more than 180 °, and the circle at this arc place is as the cross section of weft yarn 10 Size, weft yarn 10 can landing wherein, it is simple to catch.

Above-mentioned flow type catches latitude device, and the displacement of described outlet 210 is more than described water jet The total inflow of 100, prevents that knitting water is detained in tank 200.

Above-mentioned flow type catches latitude device, and described bottom of gullet is downward-sloping along the weft yarn direction of motion, Bottom described tank 200, bosom arranges described outlet 210.

Above-mentioned flow type catches the operation principle of latitude device:

" cascade " 50 is formed, due to towards weft yarn 10 after water jet 100 water outlet of flat The opening 201 in direction is " V "-shaped, therefore, when weft yarn 10 is through " cascade " 50, quilt Current be flushed to tank 200 and along with current along cell wall outlet 210 downwards move time, Weft yarn 10 can be along " V "-shaped opening 201 slide downward until its bottom, at this moment, Weft yarn 10 blocks the light that optical sensor 301 sends, and spring handgrip 300 starts weft yarn 10 fix, it is achieved accurately catch latitude.

The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality Type, all within spirit of the present utility model and principle, any amendment of being made, equivalent, Improve, should be included in protection domain of the present utility model.
