TECHNICAL FIELD
[0001] The utility model relates to the technical field of intelligent tapestry loom, concretely relates to a weft insertion and beating-up system of intelligent tapestry loom. BACKGROUND
[0002] Tapestry, also known as "carved silk", takes "continuous warp and broken weft" as the core technical feature, uses raw silk as warp and colored silk as weft, forms artistic fabric with the same front and back, rich colors, exquisite patterns and three-dimensional feeling like sculpture through local back-weaving weaving method. Because of its complex process, long time-consuming and high requirement for artisan skills.
[0003] However, due to its high dependence on manual operation, traditional tapestry production faces the challenge of industrialization. The specific performance is as follows:
[0004] (1) The production efficiency is extremely low, and the labor intensity is large. The completion of a piece of tapestry work requires the full-time manual operation of the craftsman, including warp on-machine, warp selection, weft insertion, weft guiding, weft beating-up, and weft repairing. The craftsman needs to maintain a sitting position for a long time, and the eyes, hands and brain are highly coordinated. Only a few centimeters can be woven per day, and a complex work often takes several months or even years. This production mode not only has low productivity, but also causes great burden on the health of the operator.
[0005] (2) The product quality is highly dependent on individual skills, and the standardization degree is low. The quality and effect of tapestry are directly affected by the experience, touch and aesthetics of the craftsman. In the process of weft insertion and guiding, the positioning accuracy, tension control and stability of weft are completely dependent on manual control, and problems such as weft skew, uneven tension, shedding or white exposure often occur. The beating-up force and uniformity are also dependent on the touch, and different artisans or the same artisan in different states often have differences in the woven segments, making it difficult to achieve consistency in batch production and hindering the scale and marketization of the product.
[0006] (3) The process inheritance is difficult, and the talent gap is serious. The learning time of tapestry skills is long, and it takes years of practice to master the essence. In the modern and industrial production mode, fewer and fewer young people are willing to devote themselves to this arduous and slow industry, resulting in a shortage of skilled artisans and a risk of skill inheritance.
[0007] In recent years, with the rapid development of intelligent manufacturing and textile machinery automation technology, remarkable achievements have been made in ordinary loom automation at home and abroad. For example, the rapier loom and air-jet loom have realized high-speed automatic weft insertion and beating-up. However, these devices are mainly aimed at ordinary fabrics with "continuous warp and weft", and cannot meet the special process requirements of tapestry such as "continuous warp and broken weft", local back-weaving, frequent color change and intermittent introduction of weft with varying length.

Some existing preliminary automation attempts have problems such as complex structure, poor adaptability, weak processing capacity for multi-color weft yarns and complex patterns, and inaccurate beating-up force control.
