Tube

Abstract

The invention discloses a tube comprising an external tube, a first side disc, an internal tube, a tightening assembly, a second side disc and screws. The bottom of the external tube is fixedly provided with the first side disc, the external tube is hollow and is provided with a through hole transversely, and counter bores are formed in two sides of the through hole; the internal tube is sleeved with the external tube and is provided with a first connecting hole and a second connecting hole; the first connecting hole of the internal tube and the through hole are located on the same axis; the internal tube is fixedly connected to the external tube through the tightening assembly in the through hole; the second side disc is fixedly arranged at the upper end of the internal tube, is provided with a plurality of counter bores provided with the screws and is fixedly connected to the external tube. The tube is simple in structure and practical, the internal tube is capable of extending by the certain distance from the external tube according to the requirements, more yarns can be winded, different using requirements are met, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a bobbin. Background technique [0002] With the increasing development of my country's economy, it has driven the development of my country's textile industry, and the textile level has become higher and higher. At the same time, it has driven the reform and innovation of textile machines, and the importance of the textile industry has also increased day by day. In the textile industry, the bobbin is an important part of textile machinery, and its main function is to wind the processed yarn for processing in the next process. The general structure of the existing bobbins is that two side discs are connected through the inner tube. In actual use, it is found that because the length of the inner tube is fixed, the number of spinning threads wound on the inner tube is also fixed. Sometimes the inner tube is wound After full spinning, there are still some spinning threads...

AI Technical Summary

Problems solved by technology

The general structure of the existing bobbins is that two side discs are connected through the inner tube. In actual use, it is found that because the length of the inner tube is fixed, the number of spinning threads wound on the inner tube is also fixed. Sometimes the inner tube is wound After the yarn is full, there are still some spinning yarns left. At this time, we can only change a bobbin to continue winding, which causes a waste of the bobbin, reduces the processing efficiency, and increases the investment cost.
