SGA type flexible rapier loom
The SGA788 flexible rapier loom is a new type of rapier loom independently developed by Shijiazhuang Fabric Machinery Co., Ltd. based on national conditions. The frame adopts two large wall panels, two bottom beams at the front and rear, an upper front breast beam, and a rear middle beam to form a stable frame. Three front and rear cross braces are also fixed, which further enhances its stability and allows it to stand on the big floor. The two small wall panels on the wall panel, the front and rear upper beams, the diagonal braces connected between the small wall panels and the front and rear upper beams lay a solid foundation for the installation of the dobby and the lifting heald shaft. Main transmission mechanism: After the electric motor is energized, it drives the pulley of the sliding sleeve on the crankshaft bushing to idling through the V-belt. The starting and braking of the loom are realized by operating the electromagnetic clutch and brake to engage or disengage. The crankshaft rotation of the weft insertion mechanism drives the reed base foot to swing by holding hands, so that the support leg connected to the reed base foot drives the fan gear to swing. The main idler in the weft insertion leisure and the crankshaft rotation drive an eccentric sleeve fixed on the central axis. The rotation of the fan gear makes the fan gear relative to the reed seat foot through a connecting rod. It is transmitted to the sword transfer box, and the bevel gear in the sword transfer box drives the sword transfer wheel. In this way, the swing of the fan gear is transmitted to the reciprocating rotation of the sword transfer wheel through the meshing between the gears, thereby driving the sword belt together with the rapier head to complete the weft insertion. Beating-up mechanism adopts a crankshaft hand-operated beating-up mechanism. During leisure, the crankshaft is connected to the reed base foot mounted on the rocking shaft through the hand-holding hand. The steel reed and reed base are mounted on the reed base foot. When the crankshaft rotates, the reed base foot is driven to swing through the crank and the hand, and the steel reed mounted on the reed base foot completes the beating up motion. Opening mechanism This machine is divided into two types: multi-arm opening and pedal opening. The dobby opening transmits power to the dobby machine mounted on the upper beam through the sprocket on the crankshaft. The lifting and lowering of the upper blade arm of the dobby machine acts on the heald frame through the pulley and the heald hook through the wire rope. At the lower part of the heald frame, two The two sides are respectively pulled by the tension springs hooked on the return heald box, thereby forming a shed. When the central axis of the pedal plate opening rotates, the cam fixed on the central axis presses down the rotor, pulls down the lifting hook, heald frame and lifting belt through the treadle rod, and causes the lifting pulley to rotate, and the other heald pulley rotates. The frame is pulled upward, forming a shed. Warp let-off mechanism adopts an external automatic let-off mechanism equipped with a weaving beam detection mechanism. During the weaving process, the warp yarns are continuously fed out. The application of the warp tension adjustment device and the weaving beam detection mechanism ensures that fixed-length warp yarns with uniform tension are fed out during the let-off process. Coiling mechanism adopts worm and worm gear intermittent coiling mechanism. The reciprocating motion of the guide hook foot installed on the reed base foot causes the coiling rod to swing back and forth, and a connecting rod drives the support head rod, so that the support head supports the ratchet wheel, and then drives the worm wheel through a worm coaxial with the ratchet wheel. The bristle roller rotates to take up the fabric. By changing the number of teeth of the ratchet and the number of teeth at one time, it can adapt to a wide range of weft density changes. Color selection mechanism The control signal of the color selection mechanism of this machine is controlled by the pattern plate system on the dobby machine. The last two, four and six blades of the 20 blades in the dobby machine are used for weft selection. Therefore, this machine Weft selection is divided into 2 colors, 4 colors and 6 colors. Weft stop and warp stop device This machine is equipped with electrically controlled weft stop and warp stop devices, which are sensitive in response and reliable in action. Use and maintenance In order to maintain the mechanical performance of each operating part of the loom, a reasonable refueling system should be adopted to prevent wear and tear of the friction parts and affect the life of the loom. Key parts such as hand bearings and hand bolts, crankshaft bearings, bottom bracket bearings, crankshaft support feet, etc. should be refueled once every shift. The oil of the helical gearbox should be changed every 1000 to 1500 shifts. The rear beam support legs, tension shaft support legs, and the rotating points of the coiling mechanism are refueled every 10 shifts. Use a grease gun to inject butter into the V-belt pulley, weft insertion gear seat, and each gear meshing area once every 90 shifts. Clean regularly to remove flying flowers and oil stains, and more importantly, do it once every six months to extend the life of the loom. Model indication:
