G type flexible rapier loom
The G1731 flexible rapier loom is a new type of rapier loom independently developed by Zhengzhou Fabric Machinery Co., Ltd. (formerly Henan Fabric Machinery Factory) based on domestic market demand. It is a universal and reliable loom for weaving small batches and large batches of fabrics with frequently changing varieties. It uses separate reed base conjugate cam weft beating, space crank rocker mechanism weft insertion, electronic let-off, mechanical or electronic take-up, mechanical or electronic color selection and other structures, and uses microprocessing to monitor and control the weaving. All machine functions. Scope of application and fabric varieties Suitable for weaving thin, medium, thick and various popular fabrics of cotton, wool, silk, linen, chemical fibers and other natural and chemical fibers, such as shirt materials, voile, denim, corduroy , combed wool fabrics, decorative fabrics and industrial fabrics, etc. The left and right cast iron wall panels of the rack adopt a box structure. Their complex shape makes them more rigid than ordinary wall panels. The two wall panels are made of several beams made of square steel, channel steel, round steel and other profiles. connect. Therefore, the entire frame is firm and has good balance performance, allowing the whole machine to operate stably and reliably. Transmission mechanism The main motor drives the high-speed shaft through a single V-belt. The actions of the electromagnetic clutch and brake installed on the high-speed shaft are controlled by the electronic control box. Within a certain speed range, adjusting the number of pulley compensation pieces can change the speed of the loom, which is convenient and reliable. The beat-up mechanism consists of reed base, short reed base foot and conjugate cam beat-up. The reed holder is driven by conjugate cams and cam rotors distributed in the wall panels on both sides of the loom. The cam and rotor rest in a forced oil bath connected to the central lubrication system. Weft insertion mechanism: Single-side weft supply, clamping rapier head, flexible rapier belt weft insertion, and weft center transfer. Shedding mechanism Dobby shedding, can hold up to 20 heald frames, the thickness of the heald frame is 12mm. The let-off mechanism adopts intermittent electronic let-off, and the rotation and stop of the let-off motor are controlled by the position of the tension roller. It consists of 5 pairs of bevel gears of different specifications to meet the requirements of fabrics with different weft densities. Coiling mechanism Continuous coiling mechanism is conducive to increasing the speed of the loom. Weft selection mechanism mechanical weft selection. Mechanical weft selection is controlled by a dobby machine and can select up to 6 colors. Electronic weft selection The main control box controls the weft selection execution electromechanical latch hook to attract iron to realize the selection of 1 to 8 colors of weft yarn. Automatic search for broken weft When the loom stops due to broken weft, the main control box starts the slow motor to drive the shedding, hemming, coiling and other components to reverse one circle, making it easier for the operator to find the broken weft. Hemming mechanism Standalone hemming mechanism, the hemming opening time and the ground tissue opening time can be adjusted separately according to actual needs. Lubrication device There are two methods of lubrication for the machine: oil bath and circulating lubrication. Control system The electronic control system has button control functions such as automatic positioning and parking, forward and reverse idle, forward and reverse weft search, start, emergency stop, etc., as well as warp tension adjustment control functions. Various automatic shutdown warning functions such as weft breakage, warp breakage, tension failure, insufficient oil pressure, overload protection, etc.
