Abstract

The utility model relates to an improvement for a boat shuttle of a loom. Both sides of a boat shuttle are respectively provided with two rotating wheels, and the bottom is provided with two strip-shaped flanges; a shell splinter is arranged in the boat shuttle; the shell splinter can rebound to the original position after is moved by a spring fixed on the boat shuttle; the spring is fixed onto a sliding adjustment sheet; when the boat shuttle is driven by the pulling shuttle equipment of a circular weaving machine to circle on a circular orbit, the rotating wheels on both of the two sides of the boat shuttle can reduce friction force, and the strip-shaped flanges at the bottom of the boat shuttle can prevent filling from being clamped in the orbit, and the diameter of a filling roll in the boat shuttle is decreased after the filling roll runs, and the shell splinter bunts the filling roll lightly by the driving of the spring to ensure the filling roll not to loose caused by the slide-out of the filling. Thus, the loom acts smoothly, and the utility model has substantive characteristics and progress.

Description

Improvement for boat shuttle of loom

The utility model relates to a kind of improvement of knitting yarn motor vessel shuttle, refers in particular to a kind of improvement of installing weft yarn volume and weft traction with the ship tatting structure that gives braiding.

At present, the known yarn motor vessel shuttle of knitting, its runner concentrates on a side, make other side still can with track friction, influence ship shuttle surround orbit speed, and reduce its life-span, and the ship shuttle is during around the circuit orbit of circular loom, because of ship shuttle and track are to contact with runner, so ship shuttle body and track have a distance, yarn often is stuck in therebetween, and it is not smooth that spinning process is carried out, in addition, shell fragment in the ship shuttle is fixed with a spring, though can prevent that the weft yarn volume is loosening, the long-term extension spring of shell fragment makes spring tired, make it lose the effect of withstanding the weft yarn volume, so the existing yarn motor vessel shuttle of knitting not is to be best structure.

According to above-mentioned existing structural disadvantages of knitting yarn ship shuttle, the utility model provides a kind of improved structure, and can also keep its practicality and durability.

Order of the present utility model is to realize like this, mainly be in traditional both sides of knitting yarn motor vessel shuttle, respectively establish two runners, runner and its bearing are integrally formed, the bottom surface is provided with two strip flanges, one shell fragment is arranged in the ship shuttle, slightly curved, during its action, a spring stretches, spring is to be fixed on the fixing trimmer of an adjustable bolt bolt, begin action when knitting the yarn machine, the ship shuttle is driven by the shuttle sliding device of circular loom, move along circular orbit around circular loom, the runner of ship shuttle both sides can reduce ship shuttle and interorbital frictional force, and two strip flanges of bottom surface can prevent to knit yarn and are stuck between ship shuttle and the track, and the weft yarn volume in the ship shuttle is because of weft yarn piece speed ground is skidded off by the weft yarn guide rod, its diameter is gradually little, its arc spring lamination is because of the spring that stretches, and contacts at the weft yarn volume, and the weft yarn volume is not become flexible because of diameter diminishes, produce the spinning condition of poor, spring used of a specified duration, can produce tired phenomenon, can adjust trimmer, shorten the spring stretching distance, and a kind of have practicality and the good improvement structure of knitting yarn motor vessel shuttle of effect are provided.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a stereogram of the present utility model;

Fig. 2 is ship shuttle service chart on the W track;

Fig. 3 is that the utility model trimmer is adjusted schematic diagram;

Fig. 4 is the ship shuttle and the bottom surface structural representation of utility model;

Number in the figure:

1, ship shuttle body, 2, shell fragment, 3, trimmer, 4, flange, 10, runner, 11, the guardrail grid, 12, afterbody, 21, the shell fragment seat, 31, spring, 40 projections, 30, elongated hole, 32, bolt, O, weft yarn, G, yarn, 01, the weft yarn seat, 02, the weft yarn seat, 33, bolt, W, circular orbit.

See also Fig. 1, it is stereo appearance figure of the present utility model, as shown in the figure, respectively there are two runners 10 both sides of ship shuttle body 1, runner 10 is with the integrally formed bottom side of its bearing two flanges 4 and projection 40 to be arranged, (Fig. 3), in the ship shuttle 1 weft yarn seat 01 is arranged, 02 can install weft yarn volume O, and a shell fragment 2 stretchings one spring 31 is arranged, after peak at weft yarn volume O, spring 31 is fixed in a trimmer 3, trimmer 3, can adjust the position by a bolt, with change spring 31, the distance of stretching, ship shuttle body 1 is to drive the circular orbit W that is surrounded on the circular loom in the weaving loom by a shuttle sliding device, with the braiding yarn, as shown in Figure 2.

The end periphery is provided with guardrail grid 11 on the above-mentioned ship shuttle body 1, and its rear end is the afterbody 12 that contracts in the differential of the arc, mainly can make weft yarn avoid being hooked and the guiding of the afterbody 12 arc grille portions of contracting in the mat differential of the arc easily and skidding off, and reach the never effect of hook yarn.

Seeing also Fig. 3, is that the utility model is adjusted schematic diagram, as shown in the figure, shell fragment 2 is that bolt is fixed in shell fragment seat 21, and force-applied and swing, and a spring 31 is arranged, one end is fixed in a trimmer 3 one ends and is fixed in ship shuttle body 1 with bolt 33, and there is an elongated hole 30 at other end short round spring 31 places.But the solid bolt 32 of bolt after weft yarn volume O is installed on weft yarn seat 01,02, is promptly depressed shell fragment 2, shell fragment 2 also spurs spring 31, and in the spinning process, the weft yarn of weft yarn volume O skids off, directly then convergent is little outside the weft yarn volume O, and shell fragment 2 is because of extension spring 31, and still weft yarn volume O is pasted on the top, make it be difficult for rocking, it is characterized in that: spring 31 is because of being stretched for a long time, and its elasticity must be tired, the user can unclamp bolt 32, move and transfer sheet 3, can increase the elastic force of spring 31, prolong its service life.

See also Fig. 4, be the utility model ship shuttle both sides and bottom surface structural representation, when being pushed away the drive of shuttle seat, ship shuttle body 1 is surrounded on the circular orbit W of circular loom, in spinning process, yarn G can slip between ship shuttle body 1 and the circular orbit W once in a while, but through the two strip flanges 4 and projections 40 of ship shuttle body 1 bottom surface, after the block, yarn G is withdrawed between ship shuttle 1 and the track W, just can continue the workflow of spinning.

In sum, the utility model has improved the shortcoming of conventional ship shuttle, makes the ship shuttle have more durability, and makes the workflow of weaving mechanism more smooth and easy. And the manufacturing handling ease has substantive distinguishing features and progress in fact.
