Magnetic rotation type spindle yarn feeding mechanism

Abstract

The invention provides a magnetic rotation type spindle yarn feeding mechanism. The magnetic rotation type spindle yarn feeding mechanism comprises a shell, a micro motor, a transmission block, an adjusting lead screw, a sliding block and a yarn guiding ring. The micro motor is assembled on the upper portion of the shell, an output shaft of the micro motor is coaxial with the shell and stretches deeply into the shell to be connected with the transmission block, a rotating block is fixed to the upper portion of the adjusting lead screw, transmission between the rotating block and the transmission block is achieved through small magnetic blocks which correspond in position, the sliding block is assembled on the lower portion of the adjusting lead screw through a lead screw structure capable of sliding up and down, the yarn guiding ring extending out of the lower portion of the shell is assembled on the lower portion of the sliding block through a connecting rod, and the micro motor is a motor rotating forward and reversely. According to the magnetic rotation type spindle yarn feeding mechanism, the transmission block is driven by the micro motor to rotate, the adjusting lead screw is driven to rotate by using magnetic force through the transmission block, and therefore transmission control over the sliding block is achieved.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a magnetic rotary spindle thread feeding mechanism. Background technique [0002] Spindle, that is, the drum on the spinning machine. According to the needs of spinning, it can be equipped with different roving or spun yarns. The more yarns on the machine, the higher the spinning efficiency. In the current factories, the spinning process is usually completed by the spinning machine, but the spun yarn is collected by rotating the spindle. In order to ensure that the spindle is in a regular cylindrical or conical barrel shape when receiving the yarn, usually A yarn feeding mechanism is installed in front of the spindle, so that the yarn moves up and down periodically in the tangential direction of the spindle. This allows the yarn to be evenly wound on the spindle. However, when the yarn is wound on the spindle, the traditional feeding mechanism mostly uses a four-bar ...

AI Technical Summary

Problems solved by technology

However, when the yarn is wound on the spindle, the traditional feeding mechanism mostly uses a four-bar or cam mechanism, but the four-bar and cam mechanism are constantly moving during work. the yarn will break

Moreover, once the design and assembly of the four-bar mechanism or the cam mechanism is completed, the height of its up and down movement has been determined, so that the traditional spindle feeding mechanism can only be applied to a spindle of one height.
