Example Embodiment

[0010] exist figure 2 In the embodiment of the vertical unwinder for the weft yarn of the rapier loom in the prior art, the tapered yarn 4 is mounted on the weft storage rack support plate 6, because the small end of the tapered yarn is on the top, and the weft is passed through the yarn. The yarn feeding hole 3 on the frame 2 is placed on the weft feeder. When the yarn unwinding line speed reaches 250-270M / mi, some short fibers of the yarn rub off when passing through the yarn feeding porcelain eyelet, and fall and gather on the upper part of the tube yarn. With the increase of aggregated staple fibers, under certain humidity conditions, it is very easy to be entangled with the yarn that is unwound at high speed, forming yarn defects that are brought into the weft yarn, forming weft defects on the fabric surface.

[0011] exist figure 1 In the embodiment of the present invention, the hook 2 is installed on the tapered rod 3, the metal hook 2 is hung on the weft rack 1, and ...

Abstract

The invention discloses an inversion-type cylinder weft yarn unwinding device. The device is characterized in that a cone-shaped rod is provided with a hook, the hook is hung on a weft yarn rack, the cone-shaped rod is inserted into a paper-made cone-shaped pipe in the center of the inverted cylinder weft yarn, a bolt is arranged in a bolt hole in the lower end of the cone-shaped rod, the cylinder weft yarn is fixed on the cone-shaped rod, the yarns on the cylinder weft yarn are inserted into a broken line hole in a yarn returning porcelain base and a yarn guiding hole in a yarn guiding porcelain block and enter a weft accumulator. By the inversion-type cylinder weft yarn unwinding device provided by the invention, the problems that the weft yarns wind falling staple fiber when weft yarns are unwound and the weft yarns are carried in yarn fault is solved in a gripper loom, the quality of the cloth cover is effectively improved, and the economic benefits of enterprises are increased.

Description

technical field [0001] The invention relates to a spinning unwinding device, in particular to an inverted bobbin weft yarn unwinding device for a rapier loom. Background technique [0002] In the existing weft unwinding technology of rapier looms, the weft unwinding method of rapier looms is: upward vertical unwinding, and the installation diagram is shown in figure 2 ;The technological process is: place the package weft yarn on the package yarn support plate of the weft storage frame, with the rotation of the weft storage device, the weft yarn enters the weft storage device through the yarn introduction hole on the weft yarn creel, and the yarn is unwound When the line speed reaches 250-270M / mi, the short fiber weft on the yarn will be rubbed off when it passes through the yarn drawing porcelain eye, and the short fiber weft will fall and accumulate on the upper surface of the package yarn. Under the condition, it is very easy to entangle with the high-speed unwinding yarn...
