AI Technical Summary
Technical Problem
In the production of twisting machines, the raw wire on the yarn barrel can only be unwinded by two-thirds, resulting in the need to rewind the cylinder to form a new yarn barrel, which increases the process and reduces the production efficiency.
Method used
An unwinding device including a cotton disc made of sponge, through holes, vertical pull rods and horizontal pull rods is designed. The yarn can be smoothly unwinded from the yarn barrel and completed the remaining one-third of the yarn unwinding and twisting.
Benefits of technology
This device enables the yarn to generate sufficient air coils to unwind from the yarn barrel, avoiding the need to re-turn the barrel, improving production efficiency, and reducing waste of raw silk.

Abstract
The utility model discloses a backing-off device for improving straight twisting efficiency, which comprises a cotton disc made of sponge, the cotton disc is placed on a support table, a series of through holes arranged at intervals are arranged on the cotton disc, the diameter of each through hole is smaller than that of a spool, the lower end of the spool is embedded into the elastic through hole, a vertical draw bar is arranged right above each through hole, and the vertical draw bar is connected with the vertical draw bar. The vertical traction rod is provided with a first porcelain eye for the yarn to penetrate through, the horizontal traction rod is installed above the vertical traction rod, the horizontal traction rod is provided with a second porcelain eye for the yarn to penetrate through, the yarn drum is a small yarn drum unwound by the winding frame, and one third of the yarn is wound on the yarn drum. According to the utility model, the yarn can generate enough balloons to be unwound from the spool, the rest one third of the yarn is unwound and twisted, and the problems that rewinding is needed again, the working procedures are increased and the production efficiency is reduced are solved.
