LA series air-jet loom
LA600 series air-jet looms are a series of air-jet looms developed and produced by Shenyang Hongda Fabric Machinery Co., Ltd. of Jingwei Fabric Machinery Co., Ltd. and adopted the technology of Japan’s Nissan (NISSAN) Company. Suitable weaving varieties Suitable for weaving cotton, wool, linen, silk natural fibers and chemical fibers and blended chemical fiber fabrics of natural fibers and chemical fibers. It can weave various light and heavy fabrics such as high-grade shirt cloth, fine denier (special) georgette, corduroy and denim. The fabric weight range is 30~500g/m2. Main structure: This machine adopts cast iron box wall panels, steel pipe supports to store gas, and the frame is stable. Shedding device Crank shedding can adopt cam shedding and dobby shedding devices. The cam shedding can be equipped with positive or negative type, the dobby shedding can be equipped with electronic or mechanical type, and it can be equipped with 16-page heald frame at most. The weft insertion device adopts a spindle nozzle and an opposite-shaped reed to coordinate the weft insertion method. There are single-jet, double-jet, and four-jet free-style weft insertion methods. The high-follow-up solenoid valve is controlled by a microcomputer, and the injection is uniform and powerful. Weft detection device adopts double weft detection head method for weft detection, which can detect whether the normal weft yarn is in place or whether the weft yarn is blown out. It is sent by high-performance reflective and transmissive weft finders. Beat-up device Six-link double-sided beat-up mechanism provides more sufficient weft insertion time. The winding device adopts a mechanical continuous winding or a winding method that can be equipped with an electronic winding device (optional), and the cloth dropping operation can be performed while the machine is running. Since the winding tension can be adjusted freely, the tightness of the fabric can be kept consistent. Warp let-off device Electronic let-off (ELO) is a standard device and is controlled by a microcomputer. Equipped with an AC servo motor with high-speed response characteristics, it controls the warp tension and eliminates tight paths caused by starting and stopping. The length measuring device adopts a weft storage and tension measuring method that electronically controls weft storage and electromagnetic claw movement in and out. In order to avoid the resistance of the length measuring drum to the weft yarn and improve the weft picking performance, it is equipped with three types of weft feeders: steel wire type, roller type and yarn guide type. Operation control device: Stand-alone electric control frame, built-in PLC control system or CPU control system. Equipped with human-machine interface display or CRT (industrial television) preset device. Information such as loom operating status, fault causes, weaving process parameters and fabric setting conditions can be displayed on the display CRT screen. Enter various data through function keys. Various setting parameters can be saved for a long time through the memory card or input to other looms at any time. Lubrication device Centralized refueling and box-type oil bath.
