[ field of technology ]

The invention relates to a composition device of a water-jet/air-jet loom, in particular to a novel weft accumulator of the water-jet/air-jet loom, and belongs to the technical field of textile machinery.

[ background Art ]

Weft accumulators are devices on textile machinery that handle weft yarns. When the loom works, as the weft yarn running speed is high, yarns are supplied from yarn groups directly and are easy to break, so that the production efficiency is affected, the yarn with a certain length can be wound on the yarn winding frame rapidly under the action of the weft accumulator, and the yarn can be discharged at a very high speed when needed, so that the weaving speed is improved and the breakage rate is reduced.

Existing (water/air jet) loom yarn accumulators are classified into mechanical yarn accumulators and electronic yarn accumulators. The weft accumulator is characterized in that the fixed length of the mechanical weft accumulator is realized by a fixed length wheel which is synchronous with a main shaft of a loom according to a certain transmission ratio, weft yarns are wound on a fixed length disc, the fixed length disc is designed into a cone with a certain gradient, the weft yarns are spirally wound on the fixed length disc in a front-back extrusion mode, and the weft accumulator has little damage to the weft yarns and has the defect that the weft yarns are easy to wind together.

The electronic weft accumulator is divided into a roller type accumulator and a vibration type accumulator, and the two weft accumulators realize the interval yarn arrangement of weft yarns. The roller type weft yarn machine has stable running and little damage to weft yarns, and has the defect of complex mechanism process. Vibration type weft accumulator is the mainstream weft accumulator at present, has been widely used, but because of the existence of vibration source has non-negligible influence to weft accumulator's operating condition life-span, noise and to weft yarn's damage.

Therefore, to solve the above-mentioned problems, it is necessary to provide a novel weft accumulator for a water/air jet loom to overcome the drawbacks of the prior art.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: a novel weft accumulator of a water/air jet loom is used for storing and conveying weft yarns and comprises a shell, a weft storage control motor, a yarn drum, a yarn discharging body, a yarn discharging ring, electromagnetic needles and a yarn winding frame; the weft storage control motor is arranged on the shell, and is connected with and drives the winding creel to rotate; the yarn discharging body is arranged on the yarn winding frame and is obliquely arranged in the direction close to the axis of the yarn winding frame; the weft yarns are wound on the yarn discharging body and the yarn drum at intervals; the electromagnetic needle is also mounted on the housing, can be positioned above the yarn-placing ring, and can control the release and the blocking of the weft yarn.

The novel weft accumulator of the water/air jet loom of the invention is further provided with: the yarn winding frame is provided with a yarn outlet; the yarn discharging body is arranged at a position of 180 degrees corresponding to the yarn outlet.

The novel weft accumulator of the water/air jet loom of the invention is further provided with: the yarn placing ring is arranged on the yarn drum and is positioned right below the electromagnetic needle, and weft yarns smoothly slide out through the surface of the yarn placing ring; the yarn discharging body extends below the yarn discharging ring; the needle bar of the electromagnetic needle can freely go in and out of the round hole corresponding to the yarn placing ring.

The novel weft accumulator of the water-jet/air-jet loom is also provided with: the front end of the yarn discharging body is tilted upwards horizontally.

Compared with the prior art, the invention has the following beneficial effects: the novel weft accumulator of the water/air jet loom has simple structure, convenient use, stable operation and low noise due to the existence of a vibration source in the non-active sense; the weft yarn feeding device has the advantages that the weft yarn feeding device is further provided with the yarn discharging body, weft yarns can be pushed forward, the yarns are uniformly arranged at intervals and are not easy to wind, and meanwhile, the damage to the weft yarns is reduced to the minimum degree due to the fact that the contact area between the weft yarns and the yarn drum is reduced.

[ detailed description ] of the invention

Referring to fig. 1 to 8 of the drawings, the invention is a novel weft accumulator of a water/air jet loom for storing and conveying weft yarns 10, which comprises a shell 1, a weft storage control motor 2, a yarn drum 3, a yarn discharging body 4, a yarn discharging ring 5, an electromagnetic needle 6, a yarn winding frame 7 and the like.

Wherein, the weft storage control motor 2 is arranged on the shell 1, is connected with and drives the winding creel 7 to rotate.

The yarn row body 4 is mounted on the yarn winding frame 7 and is inclined to the axis direction near the yarn winding frame 7. The weft yarn 10 is wound around the yarn discharging body 4 and the yarn drum 3 at intervals in this order. The front end of the yarn discharging body 4 is tilted upwards horizontally, so that the weft yarn 10 is prevented from sliding out of the yarn discharging body 4.

Referring to fig. 5 to 8 of the specification, the force-bearing principle diagram of the weft yarn 10 on the yarn discharging body 4 is shown, when the weft yarn 10 is wound on the yarn discharging body 4, the Fz is decomposed into Fx and FG under the free attractive force and the tension generated by winding because the surface of the yarn discharging body 4 is in a non-horizontal position; when the yarn discharging body 4 rotates along with the weft storage control motor 2, the yarn discharging body leaves the original contact position of the yarn, and generates a force Fy under the action of friction force; FH is the resultant force of the actions of Fy and Fx, and is the action of this force, so that the yarn continuously leaves the surface where the yarn discharging body 4 originally stays, and the yarn discharging effect with uniform interval is achieved.

An opening 41 is arranged at the front end of the yarn winding frame 7; weft yarn 10 passes out of opening 41. The yarn outlet 41 is provided at a position of 180 ° corresponding to the yarn discharging body 4. The weft yarn 10 is wound around the yarn discharging body 4 and the yarn drum 3 at intervals.

Further, the yarn feeding ring 5 is disposed at the front end of the yarn drum 3, and the weft yarn 10 slides out through the surface of the yarn feeding ring 5. The yarn discharging body 4 extends into the lower part of the yarn discharging ring 5, and keeps the yarn discharging body 4 to be always arranged below the yarn discharging ring 5, so that the weft yarns 10 can slide out orderly.

The electromagnetic needle 6 is mounted on the housing 1 above the winding coil 5 and is able to control the release and blocking of the weft yarn 10. Specifically, the needle bar 61 of the electromagnetic needle 6 can freely enter and exit the corresponding round hole 51 of the winding ring 5 in a controlled manner, thereby preventing or releasing the weft yarn 10.

The design principle of the novel weft accumulator of the water-jet/air-jet loom is as follows: because the yarn discharging body 4 with a certain gradient is additionally arranged, when the yarn discharging body 4 performs circular motion, the weft yarns on the surface of the warp yarn discharging body 4 generate forward displacement, so that the interval yarn discharging is realized, and the yarn 10 smoothly performs forward interval motion; at the same time, the contact area of the weft yarn 10 with the drum 3 is reduced, and damage to the weft yarn is minimized.

The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, but any modifications, equivalent substitutions, improvements, etc. made on the spirit and principles of the present invention should be included in the scope of protection of the present invention.
