Description

Rotary needle chain machine with pre-gathering mechanism

Technical Field

The utility model belongs to the technical field of the chain machine, especially, relate to a change needle chain machine with mechanism is held up in advance.

Background

The chain machine uses a chain as a traction and supporting body to convey materials, and the chain can adopt a common sleeve roller conveying chain or other various special chains (such as a power and free chain and a double-speed chain). The chain conveyor has large conveying capacity and is mainly used for conveying pallets, large turnover boxes and the like. The conveying chain has various structural forms and various accessories, is easy to realize accumulation and conveying, can be used for assembly production lines or used for storage and conveying of materials, and the power roller way consists of a power roller barrel assembly, an aluminum side plate, a sheet frame, a pull rod, a bearing seat, a driving device and a chain. The unpowered roller way consists of a unpowered roller barrel assembly, an aluminum side plate, a sheet frame, a pull rod and a bearing seat. The power roller way drives a traction chain by a driving device, and the chain drives chain wheels on each power roller barrel to rotate, so that the power roller way is conveyed by rotation. The unpowered roller way is used for pushing and pulling a workpiece by a person or extruding the workpiece by the workpiece and moving on a roller which can freely rotate, and the silk thread is a thread formed by twisting silk. The book stitching material is the book stitching material which is the earliest used in China historically, as early as 15 th century, loose pages are firstly made into posts and are connected into a book by thread stitching in China bookbinding history, and the used stitching thread is silk thread. The silk thread is similar to paper in color, soft, high in strength, smooth, firm and durable, so that the sewn book is flat and beautiful, but the silk thread is high in price and is generally only used for binding high-grade thread clothes, paintings and other books, and the silk thread refers to a thread spun by silk. Such as: the ancient textile machines are textile machines driven by manpower, which are strong, simple and dazzling textile machines, such as textile machines, weaving machines, cotton spinning machines and the like. The textile machine is a general name of a tool for processing raw materials such as threads, silks, hemp and the like into silk threads and then weaving the silk threads into cloth. Such as spinning pendants, spinning wheels, spindles, pedal looms, modern mechanical looms, modern numerical control automatic looms and the like. The development of textile processes and equipment has been designed according to the textile raw materials, and therefore, the raw materials have an important position in the textile technology. The fibers used for spinning in all countries in the ancient world are all natural fibers, generally three types of short fibers (wool, hemp and cotton), and the spinning sinker is the earliest tool used for spinning in the history of China, and the appearance of the spinning sinker can be traced back to at least the new age of stoneware. According to archaeological data, in early residential sites which are found in thirty-few provinces and cities of ancient textile machines in China, spinning wheels which are main parts of spinning plummets are almost unearthed. Early spinning wheels which come out of the earth are generally formed by simply polishing stone chips or ceramic chips, are different in shape and are mostly drum-shaped, round, oblate, quadrilateral and the like, and some wheel surfaces are also painted with decorations. The appearance of the spinning sinker not only changes the textile production of the original society, has a profound influence on the development of spinning tools of the future, but also is used as a simple spinning tool for thousands of years, even in the twentieth century, some nomadic Tibetan people in the Tibet region still use the spinning tool for spinning, and the number of the spindles of the ancient spinning vehicle is generally 2 to 3, and 5 at most. In Song Yuan, with the development of socio-economic, a large spinning frame with dozens of spindles is gradually produced on the basis of various kinds of conventional spinning frames. The big spinning wheel is different from the original spinning wheel and is characterized in that: the number of spindles is as many as dozens of spindles, and the spindles are driven by water power. The characteristics enable the large spinning wheel to have the prototype of modern spinning machinery and adapt to large-scale specialized production. For spinning ramie, the general spinning frame can spin 3 jin at most every day, and the big spinning frame can spin one hundred jin at most every day. During spinning, enough hemp is needed to meet the production capacity. The hydraulic big spinning wheel is an important invention for applying natural force to textile machinery in ancient China, for example, China is four centuries earlier than the West in terms of a spinning machine using hydraulic force as motive power.

Traditional chain machine mostly moves through the gyro wheel, carries out the during operation at chain machine, because the gyro wheel is not fixed, leads to chain machine to rock when using to the influence is used.
