GA type electronic jacquard trademark rapier loom
GA782 electronic jacquard trademark rapier loom is an internationally advanced electromechanical integration product developed by Liaocheng Changrun Cloth Machinery Co., Ltd. (formerly Liaocheng Cloth Machinery Factory) according to market needs. It is widely used in industrial cloth, silk weaving, decoration and other industries. Suitable weaving varieties: It is suitable for the jacquard weaving process of cotton, wool, silk, linen, chemical fiber and other fabrics. It can weave large jacquard fabrics, small jacquard fabrics and various patterns and text trademark fabrics. The rack system adopts reinforced racks, cast iron wall panels, and adds an installation system for electronic jacquard halters and cutting edge devices. The shedding system adopts an electronic jacquard machine. The number of needles of the jacquard machine is determined according to the user’s requirements. The pattern signal is transmitted to the computer control system through the reading mechanism. The computer control system controls the suction and closing of the solenoid valve through the weaving program, and then controls each needle. The upper and lower parts are relaxed to achieve various required patterns, so it is very convenient to adjust the fabric pattern on this loom, just change the program. The main transmission mechanism is driven by a 4kW main motor, an electromagnetic clutch, and then drives the weft insertion and beat-up conjugate cams in the left and right cam boxes to rotate through the reduction gearbox. The beat-up cam drives the reed base to beat up, and the weft insertion cam drives the weft insertion system to relax , the large toothed pulley on the outside of the left camshaft drives the jacquard shedding system, let-off system and take-up system, and a new anti-reversing device is added to overcome the unbalance of the electronic jacquard halter. 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 optimally designed and carefully arranged conjugate cam controls the entire weft insertion process, which can make the rapier head’s leisure pattern more reasonable and ensure stable weft tension, reliable handover and smooth operation when the loom is running at high speed. Beating-up mechanism The beating-up mechanism is driven by a conjugate cam and has a short reed base with separate feet. It uses inertia to beat up to reduce the impact and energy consumption of leisure. The beat-up conjugate cam has the same high precision as the weft insertion conjugate cam, driving a strong short reed seat to ensure the beat-up force when weaving high-density fabrics and heavy fabrics. The warp let-off system adopts a positive let-off and automatic tension adjustment device, and adds a dense weft function to meet the weaving needs of jacquard trademark fabrics. Electronic send-off can also be used. The coiling mechanism uses a worm gear, worm gear and sprocket to actively and continuously drive the coiling roller to achieve continuous coiling. And a pressing mechanism is added to ensure constant coiling. Electronic take-up is also available. Weft selection mechanism: Eight-color electronic weft selection mechanism, controlled by an electronic control system, allows the selected weft yarn to be introduced into the shed according to the pattern design requirements. 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. The host operating system adopts microcomputer control and has functions such as inching, starting, various self-stops, fault display, and automatic weft selection. Vacuum Mechanism In order to promptly clean the fiber dust in the yarn clamp of the left weft clamp, a stand-alone vacuum motor is installed on the left side of the loom, and left and right suction ports are equipped on the fixed guide rail.
