Description

Technical Field

[0001] This utility model relates to the field of air-jet loom technology, and in particular to a scissor-splitting device for an air-jet loom. Background Technology

[0002] Air-jet looms are shuttleless looms that use jet airflow to guide the weft yarn through the shed. The working principle is to use air as the weft-guiding medium; the compressed airflow generated by the jet creates frictional traction on the weft yarn, pulling it through the shed. The jet of air achieves the purpose of weft insertion.

[0003] In the prior art, Chinese Patent Publication No. CN217536296U discloses a splitting device for an air-jet loom, including an air-jet loom body and splitting shears mounted on the air-jet loom. The air-jet loom body is equipped with a cleaning mechanism, which includes a mounting frame and an air pipe. The mounting frame is positioned along the width of the air-jet loom body, and the air pipe is positioned directly above the splitting shears. The air pipe is hollow inside and open at the top and bottom, with one end connected to an air pump. When the splitting shears cut the fabric, the air pump is activated, drawing air into the air pipe. The dust generated by the splitting shears cutting the fabric is sucked away by the air pipe and discharged through the air pump, effectively reducing dust dispersion in the workshop and minimizing fabric dust problems during the splitting process.

[0004] However, in actual use, this utility model only performs suction from the top of the fabric during dust removal, making it inconvenient to suction from the bottom of the fabric. The dust at the bottom is easily blocked by the fabric, making it difficult for the cleaning mechanism to clean it thoroughly. Therefore, improvements are needed. Utility Model Content
