Maintenance Free Direct Drive System Makes Looms More Stable.

China Spin The CG6500 rapier loom produced by mechanical Limited by Share Ltd uses the advanced maintenance free direct drive system. The system is composed of a new main motor, such as beating up, weft insertion, opening and weft insertion by means of coupling, reducer and loom spindle. The starting torque of the new main motor is very large, much larger than that of the ordinary three phase asynchronous motor. loom The main drive eliminates the need for belt pulley, belt and clutch, simplifying the mechanical structure, reducing the wearing parts and improving the reliability. This is the main transmission mode commonly used by rapier looms abroad at present.

At present, the main motor of direct drive is variable reluctance motor, switched reluctance motor and servo motor. These motors can produce larger starting torque, but the control system is relatively complex and the cost of hardware is relatively high. The CG6500 rapier loom uses the three-phase asynchronous motor with variable frequency control as the main drive motor. Compared with other kinds of motors, the hardware used in this way has the advantages of low cost, simple system and high reliability. However, the starting torque of the frequency conversion control mode is relatively small, so that the loom can not reach the rated speed in a short time, and the starting gear is easy to generate.

To make up for the shortage, CG6500 Rapier loom The control system will adjust the weaving position, warp tension, weft insertion mode and other variable parameters in the loom start stage, and automatically adjust and avoid starting the gear. After years of extensive use and verification by textile mills, the main transmission mode can guarantee weaving quality and high reliability.

The CG6500 free rapier loom adopts the maintenance free direct drive device to transmit the power directly to the spindle, and control the speed adjustment of the loom, the automatic leveling of the shed and the automatic search for weft breaking. The mechanism has no driving belt and no clutch, so it is free of maintenance, automatic setting speed, variable speed weaving, circular lubrication of transmission system, and evenly distributing braking force on both sides of looms.

Unlike other current rapier loom's main drive direct drive mode, the CG6500 rapier loom adopts bilateral braking mode, that is, the left side of the loom is driven by the main motor, and the loom is braking on the right side by a special brake. Normally, when the brake is stopped, the loom will stop at rated speed within the 1 turn time. This requires great braking torque, especially in the case of high speed or heavy haul weaving. The whole transmission system has a very heavy impact when braking. The brake torque on both sides of looms can be rationally allocated in the design stage by using bilateral braking. Loom can brake the motion mechanism of the loom unilaterally with a smaller braking torque when braking, and the impact load on each side of the motion mechanism is relatively small, which is conducive to reducing the loss risk of high-speed motion parts and improving the reliability of looms.

In addition to the maintenance free direct drive system, the CG6500 rapier loom also uses a spatial articulated transmission mechanism for weft insertion. The mechanism has short transmission chain and rigid mechanism. It was first invented by Swiss Sulzer Ltd and applied for patent. At present, some similar rapier looms have been used at home and abroad. However, some parts of the weft insertion mechanism of the CG6500 rapier loom have been optimized on the original basis, and the smallest weft movement deviation, optimized weft transfer and lower weft acceleration have been achieved by Sulzer Ltd. The design speed of the rapier loom can reach 700 rpm.

The CG6500 rapier loom is also designed with no sword and guide hooks, and a sword belt guide is installed outside the shuttles. The sword belt guide hook is not installed in the whole shed mouth, and the sword head and the sword belt are exactly close to the reeds and fly on the warp yarn. In the range of shuttles, there is no interference between the belt guide and the hook. The weft insertion method is suitable for most fabrics, especially for woven fabrics with high density and warp. The CG6500 rapier loom is different from other rapier looms. It can adopt the weft insertion method without sword and guide hooks in the 170~360 cm wide width series, and the service life of the belt is much higher than that of the weft insertion with the belt guide hook. The CG6500 rapier loom can also be provided with a sword belt support plate by changing the belt steering module, and is used for weaving difficult to knitted varieties such as easy to stick warp yarn.

The design of CG6500 rapier loom is concise and compact, and the arrangement of the institutions is reasonable. Torsional frame has a higher overall rigidity and strength. It can maintain a very low vibration level when the loom runs at high speed. Looms can be placed directly on the ground without the need for anchor bolts, which can be used for high-density fabric or heavy weight with high tension. Textile Weaving requirements.

G6500 series rapier looms originate from Suhl Shou technology, representing the most advanced rapier loom technology in the world today. China Textile Machinery Limited by Share Ltd bought it in 2011, including G6500 series rapier looms, G6500F series rapier looms and G6500T series industrial textile rapier loom technology, covering all the technology and global sales rights from design, manufacturing process, assembly and weaving process. The products are made in China, and the models are CG6500, CG6500F and CG6500T. The gradual absorption and localization of CG6500 series rapier looms will greatly enhance the current technical level of rapier looms in China.
