Usually, the types of FIBC big bag fabric can be divided into tubular rolled fabric and flat rolled fabric. The circular looms with different shuttle handles used in weaving are suitable for weaving FIBC big bag tubular fabric or flat fabric with different folding diameters. In the weaving process, the quality and other requirements of the fabric include: weaving density, weaving fabric width, fabric tensile strength, woven fabric superficial area, etc.
For small-scale workshops and ordinary operation level, when it is necessary to produce FIBC big bag fabric, to select the quantity and layout space occupation of circular looms in combination with the actual suitation of purchasing embryonic filament and requirements of exporting rolled fabric. When medium and large-scale plants and enterprises with relatively high level of operation and management can meet the requirements of self-production and self-sales, it is necessary to reasonably select the qauntity of circular looms in this link, the choice of space occupation personnel ratio in combination with the output of winding yarns at the previous tape extrusion process. According to the indexes at the woven weaving process, which considers the number ratio of warp spindles, the thickness and tensile strength of warp and weft yarns, and weft shuttle shooting-in number when selecting one or more FIBC big bag circular looms. Then combined with the blemish requirements of FIBC big bag printing, sewing and inspection, the yield requirements of circular loom will be higher.
As the purchasing demand or export demand of flat rolled fabric, hot cutting can be arranged at the top of circular loom production process to achieve winding flat fabric on both sides, meanwhile, according to specific requirements, ultrasonic split cutting can be additionally added to achieve flat fabric winding.
Three sections constitute the main motion structure of FIBC big bag circular loom. The formation of the warp opening(shedding) needs mutual linkage with the movement of the cam. There are many kinds of cams. Generally, plane cam control is selected, which processes the cam curve formed by the shuttle that adapts to the third change of the warp opening in the plane of the plane wheel.
The warp frame comprises a warp steel pipe or shape steel, strut shaft and compass; Transport through warp roller is mainly configured as an automatic warp roller, which is driven by a torque motor, adopts to control the speed of the motor by a frequency converter, so that the warp yarn can maintain a stable tension during the let-off.
When configuring the winding structure, pay attention to the need to balance and stabilize the tension during the winding process.
The electrical control system section: Three main components ( switch cabinet, electrical control cabinet and operating touch screen ). The electric control cabinet mainly mutual linkage the movement of the main unit, transport through warp structure and winding structure to operate as a whole; Switch cabinet controls warp stop, warp change, weft stop, weft change operation and automatic troubleshooting. Operating the touch screen can mainly set the parameters of the let-off warp structure, winding system and tension of warp.
For different situations of purchasing, exporting and self-production, 10 shuttles FIBC big bag circular loom is relatively suitable for weaving tubular fabric and flat fabric with large range of folding diameters.
