Description

Drawing frame

Technical Field

The utility model relates to a weaving equipment technical field, concretely relates to drawing frame.

Background

The drawing frame has the main structure including feeding mechanism, drafting mechanism and sliver forming mechanism, and can improve the internal structure of sliver, raise the length homogeneity of sliver, reduce weight unevenness, straighten and parallel the fiber in sliver, reduce hooked matter, make the fineness meet the requirement, and mix different kinds or different quality of material homogeneously to reach the required mixing ratio. The drawing frame is a common apparatus in spinning processing, and has the functions of straightening and paralleling fibers in raw slivers through drafting and merging, reducing hooks and reducing weight unevenness of output slivers. When more than two fiber strands are fed into the drawing frame in the same or different proportion, the corresponding drawn slivers with the same or different blending ratio can be obtained and further processed into blended yarns. The drawing process is an important process in the cotton spinning process, and the quality problem which is not solved in the drawing process is further worsened in the post-process. The drawing speed of the drawing frame is a comprehensive mark for measuring the modernization of the drawing frame, the higher the speed is, the more easily the yarn quality is unstable, but the high speed is also the inevitable trend of the development of the cotton spinning process.

The temperature and humidity of air in a textile mill generally have great influence on textile skills, the strength of yarns is enhanced when the temperature and humidity reach the standard, the end breakage rate is reduced, the flying wool scene of a working environment is reduced, static electricity is eliminated, and the processes of stretching, finishing, spinning and the like of fibers can be smoothly carried out. This is because there is a close connection between the temperature and humidity and the function of the fiber, so textile mill workshops need to maintain the corresponding temperature and humidity. The production field of the drawing process is open, the temperature and humidity are not easy to regulate, the moisture regain stability of the cotton sliver is poor, the humidity of the cotton sliver is different, the phenomenon that the cotton sliver is stuck on equipment in production is caused, the product quality cannot meet the process requirement, and the normal production is influenced; or the toughness of the sliver is influenced, so that the sliver is easy to break due to high-speed impact, and the production efficiency is influenced. The induced draft cleaning system of the drawing frame has a problem of insufficient cleaning ability. The problem causes the bad condition of wadding hanging in the air duct, reduces the working efficiency of the air suction system and increases the energy consumption. At present, a regular shutdown manual car washing is adopted in a textile mill to ensure the stability of the production quality of a drawing frame. Such a method means an increase in labor cost and an increase in management work. Therefore, the working efficiency of the drawing frame air suction cleaning system needs to be improved, the problem of cotton wool accumulation in the air duct is solved, and the cleaning system can effectively complete the task of providing a stable working environment for the drafting working area. When the high-speed drawing frame is operated, a large amount of heat is generated due to sliding caused by friction between the fiber and the surface of different materials. The coil pipe is damaged or clogged by the fast sticking of low molecular weight polymer due to the high temperature.
