[ detailed description ] embodiments
Referring to the attached drawings 1 to 3 in the specification, the utility model relates to a weft feeding device, which mainly comprises a weft accumulator body 1, a weft accumulator motor 2, a winding frame 3, a yarn drum 4, an electromagnetic needle 5, a guide wheel frame 6, a guide wheel 7, a guide wheel motor 8 and the like.
The weft accumulator motor 2 is installed in the weft accumulator body 1, both of which are prior art, and therefore, the description thereof is omitted. The weft accumulator motor 2 has a motor shaft 9, one end of which motor shaft 9 is hollow and also acts as a bobbin for the yarn 10 to pass through.
The creel 3 is mounted on a motor shaft 9 and is driven to rotate by the motor shaft 9.
The yarn drum 4 is mounted on a motor shaft 9 through a bearing. The yarn 10 passes out of the motor shaft 9 and is pre-wound on the drum 4 by the rotation of the winding cradle 3.
The electromagnetic needle 5 is arranged above the yarn drum 4 and can stop the pre-wound yarn on the yarn drum 4 to stop yarn discharging according to requirements.
The utility model discloses a woof feeding device's biggest improvement part lies in: the guide wheel frame 6 is arranged behind the weft accumulator body 1. The guide wheel 7 is pivoted on the guide wheel frame 6. The guide wheel motor 8 is connected with and drives the guide wheel 7 to rotate.
The part of the yarn 10 extending out of the motor shaft 9 is tangent to the guide wheel 7 and is supported on the guide wheel 7; meanwhile, the wire feeding speeds of the guide wheel motor 8 and the weft accumulator motor 2 are synchronous, so that the synchronous yarn conveying is realized; therefore, the yarn can be prevented from generating large tension due to the turning point after the yarn passes out of the motor shaft 9, and tension is generated in the conveying process, so that yarn breakage is avoided. Meanwhile, the rotation direction of the guide wheel 7 is the same as the yarn feeding direction of the yarn 10.
Further, the guide wheel frame 6 is provided with a yarn guide porcelain eye I12; the end part of the motor shaft 9 is provided with a yarn guide porcelain eye II 13; the distance D1 from the tangent point of the yarn 10 and the guide wheel 7 to the yarn guide porcelain eye I12 and the distance D2 from the other tangent point of the yarn 10 and the guide wheel 7 to the yarn guide porcelain eye II are both 20-60 mm.
The guide wheel 7 is provided with an arc-shaped channel 71, and the distance D3 from the lowest point to the highest point of the arc-shaped channel 71 is more than 2mm, so that the yarn can be effectively prevented from sliding out of the arc-shaped channel 71.
The utility model discloses a woof feeding device's design principle as follows: the guide wheel 8 is arranged, so that the trend of the yarn 10 is changed, the yarn is prevented from being broken due to overlarge tension at a turning point, and the placing space of the yarn cylinder is also increased; due to the equidirectional rotation of the guide wheel 7, the yarn 10 is pushed, thus reducing the tension.
The above embodiments are merely preferred embodiments of the present disclosure, which are not intended to limit the present disclosure, and any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present disclosure, should be included in the scope of the present disclosure.
