The performance and quality of the circular loom will directly affect the quality of the woven bag. This paper mainly explains the working principle of the circular loom, and further introduces the operation technology of the circular loom by introducing the working system of the circular loom in detail.
First, the main structure of circular loom
Plastic cylinder braiding machine (circular loom). Plastic cylinder braiding machine (circular loom) is the main type of braiding machine in plastic knitting enterprises. Like other looms, it has three main motion mechanisms and two pairs of motion mechanisms.
Second, the introduction of the main components of circular loom
The main machine of circular loom is composed of motor, deceleration system and frame. The sliding block is driven by the main turntable, and the sliding block drives the brown belt (brown frame), brown wire, and is equipped with a jump rod (tension rod) assembly, ring gauge, etc., to form an opening mechanism; The weft insertion mechanism is composed of shuttle bar, shuttle, etc. Circular loom has no special weft beating structure, it is driven by the tensioning rod on the shuttle front roller, through the shuttle circular movement, the flat wire into and pull to the ring gauge (knitting), that is, to complete the weft beating.
Three, the main technical parameters of circular loom:
The technical parameters of circular loom are much the same, the main technical parameters are the main machine speed, braiding width and small braiding width, shuttle number, warp and weft density, warp number and so on. The actual production capacity depends on the width of the flat yarn and the continuous weaving rate. Therefore, the relationship between the technical parameters of the circular loom and the production capacity must be understood.
Four, circular loom let off mechanism - warp frame and let off roll:
The warp frame is generally composed of steel pipe or section steel as the skeleton, and the supporting shaft and the support plate of the warp tube are arranged and fixed. The let-off roller is mostly active let-off, which has its own torque motor, reducer, and transmission chain to drive the let-off roller to rotate. The passive let-off has no driving force, and it is driven by the flat wire drawn by the main machine to rotate it, which is suitable for the flat wire with high wire density. Active let-off roll is also called automatic let-off roll.
Five, round loom winding machine - up traction system and winder.
The upper traction system is driven by the main machine at the same time, which changes the weft density by the variable weft gear, decelerates by the reducer, pulls the braided cloth by a pair of flat rollers, and the output braided cloth is rolled by the winder. The winder is made of torque motor, reducer and two-high plane rolling.
6. Electrical control system.
The electrical control system composed of electrical components mainly controls the warp stop, the weft stop, the host start and stop, the let-off system, the winding system, the circular loom with variable frequency speed regulation, and the control system is equipped with a frequency converter.
To sum up, this paper introduces the working principle and operating system of the circular loom in detail, on the basis of helping people to further understand the circular loom, better master the operation of the circular loom, improve the flat wire technology, and improve the quality of woven bags.
