Abstract

The invention relates to the technical field of spinning and provides a tensioning rod for a compact spinning device to solve the problems that imported tensioning rods are high in cost and domestically produced tensioning rods cannot meet the requirements of the production technology of a compact spinning device. The tensioning rod comprises a middle steel shaft. The outer circumference of the middle steel shaft is sleeved with at least one needle bearing. The two sides of each needle bearing are provided with locating sleeves sleeving the outer circumference of the middle steel shaft. The middle steel shaft is sleeved with separating blocks. Installing space for installing lattice aprons is formed between the separating blocks and the locating sleeves. The tensioning rod is low in product lost and can meet the requirements of the production technology of a compact spinning device. The tensioning rod is identical to the tensioning rods in the prior art in size, thereby being applicable to conventional compact spinning devices.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a compact spinning device, in particular to a tension rod used in the compact spinning device. Background technique [0002] The shape of the yarn spun by the traditional spinning device is unsatisfactory, there are many fiber fly, many edge fiber hairiness, and the fiber strength utilization factor is low. At present, most of the spinning devices used are concentrated spinning devices. The compact spinning device adopts a special-shaped straw, and small holes are arranged on the special-shaped straw. Pressing causes the fibers to gather together. The compact spinning device can solve the above-mentioned defects of the traditional spinning process, and can spin fine sand with less hairiness, high strength and evenness. [0003] For example, the invention patent with the application number 02151072.5 discloses a yarn compacting device for compact spinning, which consists of a fram...
