Technical Field

The invention relates to the technical field of cloth surfaces, in particular to a novel rapier loom trimming system.

Background

In order to process a large amount of waste yarns generated in the weaving process of the rapier loom, the left side and the right side of the rapier loom are respectively provided with a waste yarn processing system, and each side of the processing system is required to clamp 14 warp yarns and is used for clamping the waste yarns and guiding the waste yarns into a waste yarn box. Fig. 1 shows a waste yarn processing mechanism and a waste yarn processing method of a traditional rapier loom, and the processing steps are as follows: the warp and the clamping warp run forwards under the clamping of a reed together with weft, the weft is cut after passing through a scissor, the weft at the left part becomes waste yarn, the weft is clamped by the clamping warp and forwards enters a waste yarn barrel, similarly, the waste yarn treatment at the right part of the loom also adopts the same working mode, the rapier loom sold on the market at present mainly adopts the above mode to treat the waste yarn, and the defects are mainly shown in the following aspects: 1) a large amount of normal yarns are needed to be used as clamping warps, so that great waste is generated, and cost is not saved; 2) the replacement of the clamped warp needs to be finished by stopping, which wastes time and reduces the yield and efficiency of the loom; 3) the quality problem is caused by easy wire breakage; 4) the left side and the right side of the rapier loom are respectively provided with a waste yarn treatment system which needs to occupy larger space; 5) the weft yarn is wasted 3 times more on the right side than on the left side because the weft yarn requires the warp yarn to close before weft tension can be stabilized.

The existing improved rapier loom waste yarn processing mechanism is characterized in that a yarn suction port is arranged on the left side of a cloth cover, and waste yarns on the left side of woven fabrics are sucked through the yarn suction port so as to trim the waste yarns on the left side of the woven fabrics. However, the structure design can not absorb the waste yarn on the right side of the woven fabric, weft arching is often caused, and the quality of the woven fabric is affected.

Therefore, a novel rapier loom trimming system which can tension the weft yarn before the steel buckles weave the weft yarn into the fabric and can also trim the waste yarns on the left side and the right side of the fabric is needed to be designed, and the rapier loom trimming system has important application value.
