The structural device of the high-speed direct warper mainly includes the following parts:
1. Creel
It is a component for placing the package yarn, located at the rear end of the warping machine. There are many types, such as V-type, rectangular, etc., among which the compound creel is widely used. The two sets of package yarn heads on the compound creel are connected, and there is no need to stop when changing the package. Its design can accommodate a large number of package yarns and ensure that the yarn can be led out in an orderly manner, providing a source of yarn for warping. However, large creels may need to pay attention to the uniformity of yarn tension.
2. Tension device
This is a key part to ensure the quality of warping. Common tension devices include disc tensioners, liquid damping tensioners, etc. It can accurately control the tension of each yarn, so that the yarn maintains a stable tension state during the warping process. After the yarn is led out from the package, it can be adjusted by the tension device to prevent the yarn from becoming loose or overly tight due to uneven tension in subsequent movement, ensuring that the warp yarn is tightly and evenly wound on the warp beam.
3. Yarn breakage automatic stop device
During the warping process, once the yarn breaks, the device will react quickly and stop the warp beam from rotating. Through sensors and other technologies, the yarn breakage can be detected in time to prevent the broken yarn from continuing to wrap around the warp beam, affecting the warping quality, reducing the production of defective products, and facilitating the operator to quickly find the broken position for processing.
4. Yarn collecting plate
Its function is to gather the yarns in a certain order. After the yarn comes out of the tension device, it is sorted by the yarn collecting plate, which can make many yarns arranged neatly, prepare for the subsequent accurate winding on the warp beam, and ensure the orderly distribution of the yarn on the warp beam.
5. Oiler
The oiler is used to prevent the yarn from generating static electricity. The rotation direction of the oil roller is opposite to the warp yarn, and the yarn is stained with oil when passing through the surface of the oiling roller. And the oiling amount of the yarn can be adjusted by changing the speed of the oiling roller to maintain the good performance of the yarn and avoid problems such as static electricity affecting the warping effect.
6. Telescopic reed
Located in front of the warp beam, the telescopic reed can control the width of the warp yarn during the warping process. At the same time, under the action of the eccentric disk, it can make a slight movement along the axial direction of the warp beam, so that the warp beam forms a cross-winding structure, effectively preventing the phenomenon of yarn embedding and pressing, improving the unwinding conditions of the warp beam, and ensuring the winding quality of the warp beam.
7. Braking device
Generally, advanced gas-liquid conversion caliper brakes are used. When it is necessary to stop, the warp beam and pressure roller can be quickly braked to ensure that the machine can stop quickly and accurately at high speed, ensuring production safety and warping quality.
