The Sectional Warping Machine is generally composed of a creel and a warping machine head, and mainly comprises a tension device, a yarn breaking self-stop device, a warp beam winding mechanism, a warp beam pressing mechanism, a braking device, a length measuring and a full Axis self-stop device. The function of the yarn breakage self-stop device is to send a signal when the warp yarn breaks, and start the parking to facilitate the worker to find the head and the joint.
The function of the warp beam winding mechanism of the split warping machine is to rotate the warp beam to complete the winding action; the warp beam pressurizing mechanism is used to ensure the normal transmission of the friction drive and reduce the slip; ensure that the winding density is uniform and moderate, and the forming is good. Brakes can quickly stop the warp beam after yarn breakage or full shaft, preventing yarn breakage and excessive yarn wear. The length measuring and full-axis self-stop devices measure and indicate the length of the winding on the warp beam, and when the design length is full, the parking is started.
When the sectional warping machine is working, a part of the total warp yarn number required for the full-width fabric is first formed into a strip as needed, and then wound on the warping drum. When a strip is wound to the specified length, it is cut and threaded into the strand. Then the other strip is wound in parallel next to the previous strip. In this way, the strips of one root are wound in turn until they are wound up to the prescribed number of strips.
In order to form well, the warp yarns of each layer should be slightly laterally moved as the drum rotates, so that the strip has a parallelogram in cross section. In short, the full-width warp yarn on the warping drum is wound onto the weaving shaft with a reverse shaft mechanism. The feature of the split warping method is that it can be directly made into a weaving shaft. When used for warping of multi-color or different warp yarns, it is convenient to arrange the color. Widely used in small batch, multi-variety yarn-dyed, wool, silk and other production.
