Description

Technical Field

[0001] This application relates to the technical field of glass fiber production, and specifically relates to a segmented drawing machine head rotating cylinder. Background Art

[0002] In the production of glass fiber drawing, there are usually two types of drawing machines, namely direct yarn drawing machines and cake yarn drawing machines. Their speeds are high or low, and the high-speed centrifugal force is very large. The head diameter of the direct yarn drawing machine is relatively small, and the expansion and contraction of the expanding piece is mainly based on the two-end tapered sleeves. Due to the lack of space, the thrust of the middle tapered sleeve is small and can only be used as an auxiliary expansion and contraction. The middle tapered sleeves must also be symmetrically arranged, occupying a large space. On the contrary, the head diameter of the cake yarn drawing machine is relatively large. Usually, the aluminum rotating cylinder is large and long. The front half is hollowed out, and the middle of the rear half is fixed with the main shaft taper. The extension of the head length is completed by the aluminum rotating cylinder to be the same length as the expanding piece. However, the processing of the long aluminum rotating cylinder and the expanding piece is difficult, especially for the aluminum rotating cylinder. Complex processes such as drilling deep holes, turning tapers, milling T-shaped grooves, and processing stress relief are likely to cause damage, and the workload is also very large. It is difficult to guarantee the quality, especially causing trouble to users in terms of maintenance. It is very difficult to install and disassemble the ultra-long and overweight aluminum rotating cylinder, and the requirements are very high. Utility Model Content
