Gear selection method for spinning frame and spinning frame

Abstract

The invention provides a spinning frame. The spinning frame comprises a body, and a motor, a supporting head tooth, a ring rail and a winding transformation paired gear ZF / ZG which are arranged on thebody, wherein the winding transformation paired gear is formed by engaging a driving gear ZF and a driven gear ZG, and the number of teeth of the driving gear ZF is larger than the number of teeth ofthe the driven gear ZG; and the number of the supporting teeth of the supporting head tooth and the winding transformation paired gear ZF / ZG satisfy the following relationship: the number Y of the supporting teeth of the supporting head tooth=x / the spinning line density number / (ZF / ZG) / the diameter of ring, wherein x is a constant and a value y obtained by calculation is a rounded integer value. According to the spinning frame provided by the invention, when the spinning line density is small, the larger driving gear and the smaller driven gear are used, the number of teeth of the selected paired gear and the number of the supporting teeth of the supporting head tooth are adjusted according to the selection method of the invention, so that the knocking-over phenomenon in a yarn backing-offprocess can be effectively prevented after adjustment.

Description

technical field [0001] The present application relates to the technical field of spinning frames, in particular to a gear selection method of the spinning frame and the spinning frame. Background technique [0002] With the continuous increase in the speed of ring spinning frame and winding machine, in order to prevent the deterioration of indicators such as hairiness, end breakage, and coil stripping, higher requirements are put forward for the quality of bobbin forming of spinning frame and the control precision of winding forming. The traditional mechanical lifting winding forming control method is hierarchical, and its control adopts an approximate algorithm. When the ring plate is improved to electronic lifting control, the servo motor can directly control the lifting speed of the ring plate, which is stepless and accurate, and its control adopts precise algorithm. [0003] No matter what kind of algorithm it is, its calculation method is relatively complicated. For th...

Problems solved by technology

However, because the corresponding table ignores some influencing factors in the calculation, sometimes there will be technological problems when strictly following the gear selection in the corresponding table, especially when the spinning density is low, usually the smaller driving gear and the larger However, in the actual production, it is found that such a setting is easy to cause stripping during the unwinding process of the yarn, and after the discharge cam is worn out, there is another way to avoid stripping is to replace the winding and transform into a pair of gears. However, when replacing the gear, it is also necessary to adjust the number of teeth that are supported by the support head teeth. The existing algorithms and formulas are relatively complicated, and whether the adjustment is still suitable for the processing of the required density yarn needs to be tested in practice.
