Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and in particular relates to a yarn continuous supply type weft yarn rack. Background Art

[0002] In the loom, the weft thread is driven by the weft sword, passes through the shed formed by the upper warp yarn and the lower warp yarn, and reaches the right side of the cloth. When the sword head leaves the shed, the weft yarn is released. The weft yarn moves toward the weaving opening under the push of the reed to form the fabric. The waste yarn on the right side of the weaving width is sucked in by the suction nozzle installed near the weaving opening on the right side of the weaving width to ensure the smooth weaving of the next shuttle.

[0003] In the prior art, the function of the weft frame of the air jet loom is to store the bobbin yarn for use in the loom. The storage form of the existing weft frame of the loom is that it is necessary to manually pay attention to the use of the yarn on the bobbin yarn at all times. After a bobbin yarn is used up, a new bobbin yarn must be replaced in time for use in the air jet loom, otherwise there will be a stationary phenomenon. This method causes high labor intensity for the staff, and after each replacement of the bobbin yarn, there is a problem of uneven yarn tension caused by touching the tension adjustment structure. Therefore, it is necessary to make improvements to the above problems. Utility Model Content

[0005] The technical solution adopted by the utility model is: a yarn continuous supply type weft yarn frame, including a base and a column fixed on the middle part of the upper end surface of the base, and is characterized in that: a plurality of weft yarn frames with adjustable height and angle are adapted and connected to the column, and each weft yarn frame is equipped with a plurality of bobbins, a yarn clamp is provided on the weft yarn frame, and the weft yarns of the plurality of bobbins on each weft yarn frame are connected end to end as a whole through the yarn clamp and are led into the air jet loom.

[0006] Wherein, the weft yarn rack includes no less than two weft yarn rods, the connecting ends of the weft yarn rods are fixed on the columns in an adjustable height and angle, the protruding ends of the weft yarn rods are fixed with hanging rods, and the bobbin yarn is sleeved on the hanging rods.

[0007] Furthermore, a clamping seat is fixed to the connecting end of the weft yarn rod, and the center hole on the clamping seat is adapted to be mounted on the column, and an open groove connected to the center hole is formed on the side wall of the clamping seat on the opposite side of the weft yarn rod, and the clamping seat is provided with through holes and threaded holes respectively located on the groove walls on both sides of the open groove, and a locking screw that passes through the through hole and the threaded hole and is adapted to be connected enables the clamping seat to be clamped and fixed on the column, and the height and angle of the weft yarn rod can be adjusted by loosening or tightening the locking screw.

[0008] Furthermore, the yarn gripper is fixed on the weft rod.

[0009] Furthermore, the base is a horizontal plate, and new bobbins for replacement are stored on the base.

[0010] The advantages of this utility model compared with the prior art:

[0011] 1. This technical solution optimizes the frame structure. By arranging multiple weft yarn racks from top to bottom on the column, and connecting the heads and tails of multiple bobbins on each weft yarn rack into one, the bobbins are introduced into the air jet loom through the yarn clamp, which solves the disadvantages of the traditional bobbin replacement labor intensity and the influence of tension uniformity every time the replacement is carried out;

[0012] 2. The technical solution connects the weft yarns on multiple bobbins end to end, so that the replacement of the used bobbins on each weft rack does not affect the normal yarn supply of another bobbin, ensuring the stability and uniformity of the yarn tension, reducing the difficulty of bobbin replacement and improving the replacement efficiency;

[0013] 3. The installation method of the weft rod in this technical solution is to clamp and fix it on the column through a clamp seat, which is convenient for adjusting the height and angle of the weft rod to meet the requirements of adjusting the direction and height of the weft yarn;
