Right support plate, bearing block, sprocket wheel, shaft coupling, servo motor.It is characterized by: the core of the yarn tension-adjusting gear
Function mainly send yarn axis and one time yarn axis to realize by two.Time yarn axis is consistent with yarn axle steer is sent, and described returns yarn
Axis is driven by servo motor.
Further, a sprocket wheel is installed on the described time yarn axis left side；It is described to send the yarn axis left side that two sprocket wheels, the right connection are installed
Shaft coupling.Described to return yarn axis and yarn axis both sides is sent to be fixed in left and right support plate by bearing block, the shaft coupling connects
Servo motor and time yarn axis.
Further, two sprocket wheels on described time yarn axis send the sprocket wheel of yarn axis to be connected with two respectively by chain.
Further, yarn first send yarn axis around first, then bypasses back yarn axis after Yarn-feeding mechanism submitting, finally around
It crosses second and send yarn axis, finally reach knitting point.
Further, it send the rotation direction of yarn axis consistent with yarn direction of advance, goes back to yarn rotational axis direction and yarn advance side
To opposite.
Further, it returns yarn axis and yarn axis is sent to keep operating condition, when lopping area yarn is too tight, yarn is just tightly attached to
It send yarn axis and returns on yarn axis, send yarn axis since yarn becomes larger with yarn axis frictional force is sent at this time, yarn axis is sent just yarn to be driven to turn together
It is dynamic, and time yarn axis occurs as soon as yarn since the direction of motion is opposite with yarn and skids on returning yarn axis, quickly send yarn to realize, delays
It is too tight to solve yarn.On the contrary, when lopping area yarn is too loose, yarn, which is just detached from, to be sent yarn axis and is returning yarn axis, and yarn is just at this time
It skids on sending yarn axis, no longer send yarn, and yarn can be pulled back since the direction of motion is opposite with yarn by returning yarn axis, to alleviate
Yarn is too loose.
The invention has the benefit that a kind of yarn tension-adjusting gear, returns yarn axis equipped with servo motor using one
With two passively send yarn send yarn axis.The present invention can adjustment member yarn elastic problem in time, entering each one thread
Uniform tension in order before lopping, structure is simple, facilitates back yarn, avoids the generation of broken yarn, ravellings phenomenon.
