Description

A double feeding and carding device

technical field

The utility model belongs to the technical field of spinning machines, relates to a double-feeding and carding device, in particular to a double-feeding and carding device of a rotor spinning device, in particular to a two-set feeding and carding device. The feeding and carding device of parallel rotor spinning machines.

Background technique

With the rapid development of the textile industry and the continuous improvement of the level of automation, various new spinning methods have emerged. Among them, due to its high spinning speed, large package capacity, good spinnability, and the ability to spin high-quality low-grade raw materials and low-grade raw materials, the rotor spinning machine has become the most mature and widely used spinning technology in the new spinning technology. The spinning form with the widest range and high economy. Since it was put into large-scale industrial application in the 1970s, after more than 40 years of development, rotor spinning products have developed from the initial coarse cloth, shoe upper cloth, table cloth, etc. to today's denim, slub cloth, poplin and knitwear, etc. , various non-cotton products are also actively being developed.

Rotor spinning belongs to the field of open-end spinning technology. Open-end spinning has been patented in the United States as early as 1872, but due to various reasons, it has been in the development and testing stage in the next 40 to 50 years, so it has not met the requirements of industrial production. As the former Czechoslovakia first manufactured the world's first KS-200 rotor spinning machine prototype in the 1960s, it was continuously improved and improved in the following years, and the first performance machine was produced in 1967. More advanced BD-200 rotor spinning machine that can be used in industrial production. Subsequently, Japan and Germany carried out research and improvement, and the technology of rotor spinning was advanced by leaps and bounds, and self-exhausting and suction rotor spinning machines appeared. And with the improvement of automation level, automatic jointing has also been realized in rotor spinning. Although the results have been improved many times, the key component of rotor spinning - the overall structure of the spinner has not changed much. The basic structure of the existing spinning device includes a housing, a cover, a rotor seat with an air suction cavity installed on the main beam of the main frame of the spinning machine, a rotor located in the rotor seat, and a rotor seat installed in the main frame of the spinning machine. The carding roller on the housing, the feeding roller, the yarn delivery tube and the fiber delivery channel between the carding roller and the rotor. Due to the single-set carding characteristics of the traditional spinning device, the rotor spinning has a greater application in cotton spinning products, but at the same time, the rotor spinning is also used to produce blended yarns, short and thick slub yarns, fancy yarns, etc. There are major limitations and problems with new yarns. The main reason is that different types of carding rollers have different application ranges for raw materials, and it is difficult for the same carding device to card fibers with different properties at the same time. Therefore, to a certain extent, it limits the variety of rotor spinning varieties. sex. Therefore, to expand the application range of rotor spinning and enrich the types of rotor yarn, it is necessary to improve the key component of rotor spinning - the spinning device, especially the design of double feeding and carding devices.
