Principle of circular loom

1. Plastic cylinder weaving machine (circular weaving machine). Plastic cylinder weaving machine (circular weaving machine) is the main weaving machine of plastic weaving enterprises. Like other weaving machines, it has three main motion mechanisms and two auxiliary motion mechanisms

2. The opening, weft insertion, and beating mechanism of the circular loom - the main machine

The main engine of a circular loom consists of a motor, a reduction system, and a machine base to form a transmission system; The main turntable drives the slider, which in turn drives the brown belt (brown frame), brown wire, and is equipped with a jumping rod (tension rod) component, ring gauge, etc., forming an opening mechanism; The weft insertion mechanism is composed of a shuttle rod, shuttle, etc. The circular loom does not have a dedicated weft beating structure. It is driven by the tension rod on the shuttle to drive the front roller, which runs around the circumference of the shuttle to bring the flat yarn into and pull it towards the ring gauge (weaving mouth), thus completing the weft beating

3. The warp feeding mechanism of the circular loom - warp frame and warp feeding roller:

The warp frame is generally composed of steel pipes or steel sections as the skeleton, and is composed of supporting shafts and backings that fix the warp tubes in rows and columns

The warp feeding roller is mostly an active warp feeding roller, which has its own torque motor, reducer, and transmission chain to drive the warp feeding roller to rotate. Passive warp feeding has no driving force and is driven by the flat wire pulled by the host to rotate, suitable for high-density flat wire. Active warp feeding roller is also known as automatic warp feeding roller

4. Circular loom winding mechanism - upper traction system and winding machine

The upper traction system is simultaneously driven by the host, which changes the weft density through a variable weft gear, is reduced by a reducer, and is pulled by a pair of flat rollers to weave the fabric. The output woven fabric is wound into a roll by a winding machine. The winding machine is powered by a torque motor, a reducer, and a two roller flat roller to roll the fabric

5. Electrical control system

The electrical control system composed of electrical components mainly controls warp stop, weft stop, main engine start stop, warp feed system, winding system, circular weaving machine with variable frequency speed regulation, and controls

The system is equipped with a frequency converter

6. Main technical parameters of circular loom:

The technical parameters of circular looms are similar, mainly including the main engine speed, maximum and minimum weaving width, number of shuttles, warp and weft density, number of warp yarns, etc. The actual production capacity depends on the width of the flat yarn and the continuous weaving rate during weaving. Therefore, the technical parameters of circular looms are related to production capacity and must be understood and mastered.
