Abstract

The utility model discloses a yarn cutting device with a helical-tooth blade, and belongs to a component of a ring spinning aluminum rod spindle. The yarn cutting device comprises an annular blade and a yarn cutting device base, and is characterized in that homodromous helical teeth are uniformly distributed on the outer periphery of the blade; 70-120 helical teeth are provided, and the tooth angles of the helical teeth are 10-75 degrees; included angles between the center lines of the helical teeth and the center line of the blade are 35-70 degrees. During doffing in a spinning process, the rotating speed of the spindle is lowered, yarns stop on the outermost edge of the blade, the yarns are loosened at the moment, enter the root parts of the helical teeth along with continuous rotation of the spindle, and are cut by the root parts of the helical teeth under the action of the inertial force of the rotating spindle, so that the cutting rate is over 99.9 percent.

Description

A kind ofly cut yarn device with helical teeth blade

Technical field

The utility model relates to a kind of parts of ring spinning aluminium bar spindle, particularly a kind ofly cuts yarn device with helical teeth blade.

Background technology

At present, the existing blade that cuts yarn device mainly contains two kinds of versions, and a kind of is the mouth that directly puts the first edge on a knife or a pair of scissors in the neighboring of annular body, and another kind is the mouth that puts the first edge on a knife or a pair of scissors in the neighboring of annular body, and cutting edge edge is with equally distributed sawtooth.While doffing in spinning process, the rotating speed of spindle reduces, and yarn can loosely be parked in the outermost edge of blade, cannot be cut off and continue slippage in the pause of any position of blade cutting edge, causes yarn effectively not cut off, but is torn, and cuts yarn inefficiency.

Summary of the invention

The purpose of this utility model is in order to solve the problems of the technologies described above, and provide a kind of and can effectively cut off yarn, the rate of cutting off is high with helical teeth blade cuts yarn device.

The purpose of this utility model is achieved in that a kind ofly cuts yarn device with helical teeth blade, comprise annular blade, cut yarn device seat, it is characterized in that the neighboring of blade is with equally distributed helical teeth in the same way, the helical teeth number of teeth is 70～120 teeth, helical teeth flute profile angle is 10 °～75 °, and the angle of helical teeth center line and blade centerline is 35 °～70 °.

The utility model is owing to adopting above architecture advances, while doffing in spinning process, the rotating speed of spindle reduces, yarn can be parked in the outermost edge of blade, and now yarn is lax, along with spindle continues rotation, yarn will enter helical teeth root, under the inertia force effect of spindle rotation, by helical teeth root, yarn to be cut off, the rate of cutting off is up to more than 99.9%.
