CR—flexible rapier loom
The CR-1000 flexible rapier loom is a product of Liaocheng Changrun Fabric Machinery Co., Ltd., based on the digestion of domestic and foreign advanced technologies, with the principle of improving the weaving efficiency of the loom and being able to weave heavy fabrics. It is a new type of loom with optimized design of warp, take-up, beat-up and other systems. Suitable weaving varieties can weave various natural fibers (such as cotton, wool, silk, linen) and various regenerated fibers and synthetic fibers. It is suitable for all kinds of light, medium and heavy weight fabrics and high-end fabrics such as high count and high density, variable weft density and so on. The rack part adopts reinforced rack and thickened wall panels. The structure of the whole machine is compact and strong, and it can free up a wider space in the loom for easy cleaning and debugging. The opening mechanism of the opening device adopts an active bottom-mounted dobby. According to the designed fabric structure, the lifting and lowering of the heald frame is controlled by a pre-programmed pattern paper or program. It can also be equipped with a jacquard machine. Beating-up part: The beating-up mechanism is driven by a conjugate cam and has a short reed base and separate reed base. It uses inertia to beat-up to reduce the impact and energy consumption of leisure. The reinforced reed system is adopted to appropriately increase the inertial force of the beat-up system and improve the beat-up force, which can meet the requirements of heavy fabrics. Weft insertion mechanism The weft insertion mechanism is a double sword that supplies weft from one side. The flexible sword belt driven by the conjugate cam and the clamping weft clamper transfer the weft yarn in the center to complete the weft insertion. The weft insertion stroke is achieved by adjusting the position of the slider in the cam box. The let-off part adopts positive let-off and compound adjustment mechanism to ensure uniform let-off and stable let-off tension. It can also be equipped with electronic let-off. The design adopts a strengthened let-off transmission system and a large side plate to improve its strength, which not only improves the weaving efficiency, but also reduces the vibration of the warp beam when weaving heavy fabrics to adapt to the high tension requirements of heavy fabrics. The coiling part is a positive continuous coiling mechanism, which actively and continuously drives the coiling roller by a worm gear, a worm and a sprocket. Can be equipped with electronic take-up. The coiling casing is a box type, which enables oil bath lubrication of the reduction gear, reduces heat generation, and improves transmission performance. The cantilever support structure of the reduction gear is changed to support at both ends, which improves the reliability of the transmission part. At the same time, the worm gears and gears of the coiling transmission part have been redesigned to improve the strength of the coiling transmission mechanism and meet the needs of large tension. The main transmission mechanism is driven by a 4kW main motor through an electromagnetic brake clutch to drive various mechanisms of the loom. The electromagnetic brake clutch cooperates with the electronic control system to accurately control the starting, positioning, parking, inching and other functions of the loom. Weft selection mechanism The 8-color electronic weft selection mechanism is controlled by a computer, so that the selected weft yarn is introduced into the shed according to the pattern design requirements. Control and detection adopts a microcomputer control system, with functions such as electronic warp let-off, electronic weft selection, automatic weft search, fault detection, automatic weft selection, and liquid crystal display. All operations of this loom are button operations. Jog, start, stop, forward and reverse rotation, and weft search all have their own button operations. These buttons are installed on the square beam. Indicator lights are installed on the square beam. The red light indicates stop for weft break and the green light indicates stop for warp break. The electric control box is equipped with a main motor, a control switch for the vacuum motor, a manual and automatic transfer switch, and a red emergency switch for cutting off the power supply in an emergency. Buttons etc. The selvedge device has a leno selvedge device and can be equipped with fold-in edge and hot-melt devices. Lubrication device: The main transmission gear train adopts oil bath lubrication, the balance shaft bearing adopts regular forced lubrication, and the parts without oil bath adopt sealed bearings. Vacuum Mechanism In order to promptly clean the fiber dust in the yarn clamp of the left weft clamp, a stand-alone vacuum motor with a power of 300W is installed on the left side of the loom, and left and right suction ports are equipped on the fixed guide rail.
