Description
Technical field
This utility model relates to shuttleless loom field, especially, is that the spring of a kind of shuttleless loom catches latitude device.
Background technology
Along with the level of China's textile industry improves and the growth of products export, the demand of shuttleless loom grows with each passing day,
Technology upgrading and transformation for textile enterprise of China are laid a good foundation.Develop from external shuttleless loom technology, at electromechanical
Change, speed, selecting color etc. technically, all freeed great variety, the most in recent years, China's domestic shuttleless loom development is very fast,
Having preliminarily formed industrial chain, product cost declines to a great extent, and technical performance increases.
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
Purpose to succinct wefting insertion.Owing to weft yarn flight exists resistance and gravity, therefore weft yarn is unstable, therefore in the position catching latitude end
The latitude structure of catching needing efficiency higher carries out catching latitude.
Utility model content
In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of spring to catch latitude device, and this spring is caught
Latitude device can carry out catching latitude accurately.
This utility model solves its technical problem and be the technical scheme is that
This spring catch latitude device include shears component, the optical ring induction apparatus that is coaxially disposed and slip-ring seat, described slip ring
The both sides of seat are provided with along the axial arranged slide rail of slip-ring seat, after described slip-ring seat is arranged on described optical ring induction apparatus
End, described slip-ring seat is driven by motor and can slide axially on described slide rail, and described slip-ring seat connection one is coaxially disposed
Spiral spring, the center-side of described spiral spring connects one and fixes component, and the front end of described slide rail arranges described shears structure
Part, described shears component and optical ring induction apparatus are electrically connected.
As preferably, the cross section of described slide rail is curved, and the circle at its radian place is described slip-ring seat peripheral circumferential.
As preferably, the movement velocity of described slip-ring seat is not less than the movement velocity of weft yarn.
As preferably, it is smooth arc towards the fly here surface of spiral spring in direction of described weft yarn, and and weft yarn
The surface of tangent spiral spring is done frosted and is processed.
The utility model has the advantage of:
Original state is that the spiral spring of plane is drawn into cone-shaped by described slip-ring seat, when weft yarn flies over optical ring
During induction apparatus, motor drives slip-ring seat to slide to the weft yarn direction of motion and slides, and cone-shaped spring reverts to spiral spring, spring
Space between Si diminishes, and is caught by weft yarn, owing to slip-ring seat drives spiral spring motion with the movement velocity not less than weft yarn,
Therefore, there is no need to accurately determine the position of weft yarn, so that it may accurately caught by weft yarn, serious forgiveness is high.
Accompanying drawing explanation
Fig. 1 is the side-looking structural representation that this spring catches latitude device.
Fig. 2 is the front view that this spring catches latitude device.
Fig. 3 is the sectional view of Fig. 2 labelling I, i.e. the sectional view of adjacent springs silk.
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 around Fig. 2, this spring is caught latitude device and is included shears component 120, is coaxially disposed
Optical ring induction apparatus 210 and slip-ring seat 200, the both sides of described slip-ring seat 200 are provided with along the axial arranged cunning of slip-ring seat 200
Rail 220, described slip-ring seat 200 is arranged on the rear end of described optical ring induction apparatus 210, and described slip-ring seat 200 is driven by motor
Moving and can slide axially on described slide rail 220, described slip-ring seat 200 connects a spiral spring 100 being coaxially disposed, described
The center-side of spiral spring 100 connects one and fixes component 50, and the front end of described slide rail 220 arranges described shears component 120, institute
State shears component 120 and the optical ring induction apparatus 210 above-mentioned spring that is electrically connected catches latitude device, the cross section of described slide rail 220
Curved, the circle at its radian place is described slip-ring seat 200 peripheral circumferential.
Described optical ring induction apparatus 210 can use light scanning, or infrared two-way emission type inductive head realizes flight latitude
The monitoring of yarn 10.
Above-mentioned spring catches latitude device, and the movement velocity of described slip-ring seat 200 is not less than the movement velocity of weft yarn 10.
Refering to Fig. 3, the surface of the volute spring 100 tangent with weft yarn 10 is done frosted and is processed, and prevents weft yarn 10 from coming off.
Above-mentioned spring catches the operation principle of latitude device:
Original state is that the spiral spring 100 of plane is drawn into cone-shaped by described slip-ring seat 200, when weft yarn 10 flies over
During optical ring induction apparatus 210, electric motor starting, drive slip-ring seat 200 to slide to weft yarn 10 direction of motion, cone-shaped spring simultaneously
100 revert to spiral spring 100, and the space between spring wire diminishes, and are caught by weft yarn 10, owing to slip-ring seat 200 is to be not less than
The movement velocity of weft yarn 10 drives spiral spring 100 to move, and therefore, can be strained and fixed by weft yarn 10, and then, shears component is cut
Staplings yarn 10.
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.
