Problems and improvements of rapier looms on the market (1)
The rapier loom is a kind of shuttleless loom widely used at present. Its active weft insertion method has good variety adaptability, can adapt to the weft insertion of various yarns, and has obvious advantages in multi-color weft weaving. In the process of manufacturing and using the rapier loom, SUNTECH found that some of the loom designs were not satisfactory, so the equipment was improved.
Design a new weft insertion system to broaden the range of looms suitable for weaving
Due to the wide variety of fabrics on the market at present, the yarn numbers used in fabrics vary greatly, and the weft insertion systems of most looms on the market are no longer suitable for the weaving requirements of some fabrics. In order to meet the weaving needs of some fabric varieties, SUNTECH designed two new weft insertion systems based on the existing weft insertion systems based on the yarn characteristics of some fabrics.
One is a new type of wide rapier belt single-row guide hook weft insertion system. When weaving some jacquard decorative fabrics, when the common guide hook weft insertion system is used, loops are prone to appear on the reverse side of the fabric, and there are many broken warps and wefts. Therefore, on the basis of the existing double-row guide hook weft insertion system, the rear guide hook is removed, the front guide hook remains unchanged, and the profile of the movable guide rail, the rapier belt, the fixed guide rail channel, the dial clamp and the rapier belt library are widened. Wait. In order to reduce the weft break, the weft-feeding rapier's clamping position was improved. The new wide rapier belt single-row guide hook weft insertion system can increase the speed of the loom, reduce the warp rate of the jacquard loom, and improve the production efficiency and start-up efficiency.
The second is the floating guide hook weft insertion system. When weaving fabrics such as glass fiber mesh cloth, steel wire mesh cloth, etc., due to the thick yarn number and hard material of the fabric, the existing weft insertion system guide hooks, sword belts, and sword heads wear quickly. For this reason, the shape of the ordinary guide hook has been improved, and the improved guide hook is called the suspension guide hook. When the suspension guide hook weft insertion system is used for weft insertion, the wear of the rapier belt by the lower warp yarn is reduced. In order to extend the service life of the sword head, the material of the guide groove of the weft feeding sword is changed from nylon plastic material to steel material, which enlarges the yarn clamping surface of the weft sword, and adds grooves to extend the guide hook of the weft insertion system. The life span of the sword belt and the sword head improves the efficiency of starting up.
The above two new weft insertion systems can improve the adaptability of ordinary rapier looms to different fabric varieties and broaden the loom's suitable weaving range.
