SGA series flexible rapier loom
The SGA726 series flexible rapier loom is a shuttleless loom independently developed by Jiangsu Gaochun Fabric Machinery Co., Ltd. (formerly Jiangsu Gaochun Fabric Machinery Factory) based on my country’s specific realities. This model series has the characteristics of compact structure, strong variety adaptability, convenient variety change, convenient and simple operation, high degree of automation, stable and reliable weaving, etc. The SAG726 series includes SGA726II and SGA726C. Suitable Weaving Varieties The wide adaptability of weaving varieties is one of the characteristics of the SGA726 series loom. It can weave various types of fabrics such as cotton, wool, linen, silk, chemical fiber and blended chemical fiber fabrics, with a weft density ranging from 20 to 1100 threads/piece. 10cm; the loom speed can reach up to 360r/min; changing the pulley of the main motor can easily change the loom speed. The symmetrical reed width of the fabric is 190cm, 210cm, 220cm, 230cm, and the diameter of the large roll of the cloth roller is 600mm. The diameter of the warp beam side disc is 800mm. Equipped with 6-color weft selector, controlled by PLC programming. The box-type wall panels on the left and right sides of the main structure frame are made of high-strength castings. The box is equipped with a beating conjugate cam, a reed transmission device and a transmission device of the sword transfer mechanism. The middle of the frame is supported by three special supports. The entire fuselage is low Short, high rigidity, low vibration, no need for anchor screws. The opening of the dobby opening system can be configured with the GT412 positive full-opening double-acting mechanical dobby of Changshu Textile Machinery Company. It is a left-hand downward-mounted dobby. The dobby is divided into two reading forms. One is the pattern type, which can be With 12 heald frames, you can change the texture of the fabric by changing the position of the pattern nails on the pattern plate; the other is the pattern paper type, which can have up to 20 heald frames, and you can punch holes in the pattern paper to control the shape of the heald frames. According to the law, adding some accessories to the pattern paper transmission part can also increase the number of weft cycles of weaving. The biggest advantages of these two types of mechanical dobby looms are that it is convenient and simple to change types, reliable in operation, and can be equipped with a reversing device. With the cooperation of the control function of the electric control box, this type of loom has automatic weft search and anti-weft stop functions. The dobby machine can weave plain weave, twill weave, satin weave, jacquard and other tissue fabrics. The main drive is a three-phase motor driving the main shaft of the loom through a single narrow V-shaped belt. The main shaft is equipped with an electromagnetic clutch. The electronic control system controls its starting and braking, thereby controlling the starting and braking of the entire machine. By adjusting the motor belt The size of the disc is used to change the speed of the loom. The main shaft of the loom drives various components through high-precision gear pairs. Each transmission shaft is supported by high-precision rolling bearings. The transmission is smooth and the vibration is small; the energy loss is small and the transmission efficiency is high. The reed seat of the beating mechanism is fixed on the rocking shaft supported by the rolling bearings of the frames on both sides. A pair of high-precision conjugate cams on the left and right are driven by the main shaft through high-precision gears, so that the rocking shaft drives the reed seat to perform the beating action according to specific rules. , the reed base has a large angle of repose, strong beating-up force, small impact vibration, and can adapt to the high-speed operation of the loom. Weft insertion mechanism adopts double-sided flexible rapier single-side weft insertion and clamp-type center transfer weft insertion method. The weft insertion mechanism is driven by a space crank linkage mechanism to drive the sector gear and the pinion gear meshed with the sector gear to drive the rapier wheel to reciprocate, causing the flexible rapier meshed with the rapier wheel to reciprocate, thereby achieving weft feeding and weft picking. the goal of. The warp let-off mechanism adopts a continuously automatic adjustment mechanical Hunt warp let-off mechanism. The warp yarn tension can be automatically adjusted when the warp beam changes from the large warp head to the small warp head. The warp yarn tension on the machine can be adjusted by the tension weight. The warp and weft density can be changed according to the fabric weft density. By exchanging gears, the warp let-off system has high reliability and is easy to maintain. The winding mechanism adopts a continuous mechanical winding mechanism. The fabric passes through the side support, opening roller, and winding roller from the cloth opening to the cloth winding roller. The winding roller is driven by the winding box. The winding transmission box can be adjusted according to the weft of the fabric. Replace the weft density conversion gear. Weft selection mechanism adopts an electronic weft selection mechanism, and can achieve arbitrary selection of eight-color weft yarns by setting the electronic control program. The hemming and waste edge mechanism adopts the independent conjugate cam transmission hemming transmission mechanism to make the hemming half-heald frame move up and down, and uses the Leno hemming device to perform separate leno hemming and weave out the waste edges on both sides at the same time. The hemming time can be adjusted arbitrarily according to the weaving process requirements. Idle and weft-finding and breaking systems The idle and weft-finding and breaking actions of the loom are driven by a separate slow-speed weft-finding motor. When the loom stops due to weft breakage or when dealing with weft defects, the automatic weft-finding and breaking system can be used. This system passes The slow-speed electromagnetic clutch and the weft-seeking clutch automatically make the loom reverse (or forward) to facilitate processing of weft defects. At this time, only the warp let-off, take-up, shedding and other mechanisms perform synchronous actions, while the beating-up and weft insertion are stopped. move. The electronic control system adopts PLC integrated block microcomputer control circuit. The fabric movement is controlled by encoders and sensors. It automatically monitors warp breaking, weft breaking, positioning parking and lubricating oil pressure, etc., and can realize automatic weft search, program setting and parameters. The display is carried out through the electric control box operation panel.
