Description

A three-dimensional knitting machine feeding device with variable angle for man-machine separation

technical field

The invention relates to a three-dimensional braiding machine feeding device with a variable angle for man-machine separation, belonging to the technical field of textile machinery.

Background technique

Weaving technology has a long history and can be said to be the first textile technology in ancient civilizations. Three-dimensional weaving is a kind of three or more yarns oriented along the fabric forming direction and crossed obliquely according to specific rules, so that the yarns are interwoven craft together. In the history of our country, the knitting machine was born in the early 20th century. As a kind of knitting machine, the three-dimensional knitting forming machine based on three-dimensional knitting technology was born in the late 1960s. The parts after three-dimensional knitting have a non-layered overall structure, and the section along the knitting direction can be continuously changed. Complex structure It has the characteristics of one-time molding of components, and has excellent properties such as impact resistance, delamination resistance, and creep resistance. Braided composites are widely used in aerospace vehicles, engines, automobiles, ships, construction, bioengineering and other fields.

With the development of science and technology, the three-dimensional knitting machine is also being continuously improved, and the types and shapes of its knitting parts are also increasing. It can weave a variety of structural fabrics including circular regular and special-shaped three-dimensional fabrics. Therefore, the feeding device for the three-dimensional knitting machine is also being continuously improved and innovated.

The feeding device can realize the delivery of the product. At present, in the feeding of three-dimensional knitting machines, some enterprises use manipulators to clamp the mandrel for weaving. This method is convenient and quick, and the angle can be adjusted at will, but the cost is relatively high. Another part of the enterprise often uses mechanical mechanisms to feed the mandrel. This kind of mechanical mechanism is divided into two categories, namely manual type and electric type. The electric type is mechanized transmission. This method replaces human labor, saves time and effort, and greatly reduces labor intensity, reduces labor costs and saves human resources. It really achieves low cost and high return. But the general existing mechanized feeding device is too complicated, and it is difficult to stop in time. The manual type can adjust the position of the mandrel at any time, but it requires manual operation and consumes manpower. Both manual and electric methods have their own advantages and disadvantages, and the two methods rarely take into account the variability of angle. Therefore, in order to solve the above technical problems, it is indeed necessary to provide an innovative angle-variable three-dimensional braiding machine feeding device for man-machine separation, so as to overcome the above-mentioned defects in the prior art.
