重庆长寿湖渔网厂1975年从日本进口双钩型织网机三台,用于以刺网为主的各种淡水渔网的生产。近几年来,由于淡水渔业的发展,用户除了大量需要刺网以及细线和中等粗线的网片外,对张网、防逃拦网、拖网等粗线大型网具的需求也不断增加。为了适应这一情况,对其中的一台织网机进行了技术改造。改造的网机原梭距为9.5mm,梭子厚度为7mm,线盘厚度为8.5mm,梭子间隙为1mm,能通过的最粗绵纶网线为210d/15股。而张网、拦网、拖网等淡水大型网具所用的绵纶网线为21on/18～42股,在进口原机上无法通过。因此必须增大梭距,
Changshou Lake in Chongqing fishing net factory in 1975 imported from Japan double-hook net weaving machine three for the main nematocyst nets a variety of freshwater fishing nets production. In recent years, due to the development of freshwater fisheries, in addition to a large number of need of gill nets as well as thin and medium thick mesh, the demand for large-scale, large-scale nets such as zhangwang, anti-escaping blocking and trawling is also increasing. In order to adapt to this situation, one of the weaving machine made a technical transformation. The original netting of the modified netting machine is 9.5mm, the thickness of the shuttle is 7mm, the thickness of the reel is 8.5mm, the clearance of the shuttle is 1mm, and the boldest spandex cable that can pass is 210d / 15 shares. And nets, blocking, trawl and other freshwater large nets used in the lunan cable for the 21on / 18 ~ 42 shares, the original machine can not be imported through. Therefore, it is necessary to increase the bobbin distance,
