When the utility model is used, linear type venthole when driving reversing shaft rotation by servo motor, on axis Periodical on-off will be formed with the venthole on axle sleeve；To realize being quickly converted for gas flow direction, spray is further realized It is mapped to the periodical on-off of the gas direction on tow, i.e., are as follows: when the outlet of one end, the other end holds one's breath.At the same time, in gas , can be by adjusting adjustment sheet to the circular hole shielded area on air hose in the case that pressure is certain, Lai Tigao gas is to tow Impact velocity.

The utility model is compared with prior art: fiber passes through high-frequency air flow buffer unit, alternately after air drawing Change the airflow direction of buffer unit, this mode is mainly the output revolving speed for passing through control active motor, to reach buffering dress The airflow direction frequent transitions set, as two gas outlets one end outlet, and the effect that the other end holds one's breath at the same time, in turn A kind of effect of oscillation is generated to fiber, the dispersion of increased fiber horizontally is come with this, makes the vertically and horizontally strength of final products Than reducing.Servo motor has stepper motor is incomparable to be precisely controlled, and simultaneous reactions are also more quick.The precision of device is more Height, accuracy is more preferable, and sub-wire effect is more obvious, and cloth cover is more preferable without clouding phenomenon, uniformity, while being also able to achieve automatic control System.
