Fig. 2 is the working state schematic representation of the present invention.
Embodiment
In order that those skilled in the art more fully understands technical scheme, it is below in conjunction with the accompanying drawings and specific real
Applying example, the present invention is described in further detail.
As shown in figure 1, a kind of automatic yarn-feeding device, including drive device, the drive device are specially a kind of outer mover
Brshless DC motor, include stator axis 1, the one or both ends of the stator axis 1 are fixedly mounted on straight-bar machines 10, the stator
Some stators 2 are fixed with axle 1, the stator 2 includes Exciting Windings for Transverse Differential Protection that is cored and being wrapped on iron core, the stator 2
Periphery is set with mover 4, and the mover 4 includes permanent magnet pole, and the outer circumference surface of the mover 4 is provided with one layer of wearing layer
5, the axial both ends of the mover 4 are additionally provided with bearing 3, and the bearing 3 is sleeved in stator axis 1, and the bearing 3 is specially to slide
One or more in bearing, needle bearing, cylinder roller bearing, deep groove ball bearing, the bearing 3 are used to ensure that mover 4 exists
Stationarity in rotation process, avoiding running at high speed down gets loose, while reduces the heating under running at high speed, and avoids because hair
Thermal conductivity causes mechanism-trouble.
The wearing layer 5 is specially wear-resistant alloy layer or ceramic layer, and the wearing layer 5 is advantageous to improve the excircle of mover 4
Service life of the face in guide function, reduction send yarn to be worn to caused by the outer circumference surface of mover 4 for a long time.
Cord roller is additionally provided with parallel to the stator axis 1, the quantity of the cord roller is more than or equal to 1, preferably two, and
The axial both sides of the stator axis 1 are respectively arranged at, when the quantity of cord roller is two, one of them is yarn-feeding roller 6 and gone out
One end of yarn roller 7, yarn-feeding roller 6 and yarn roller 7 is fixed on straight-bar machines 10, and the axis on the yarn-feeding roller 6 perpendicular to yarn-feeding roller 6 is set
It is equipped with several and send yarn hole 8, the axis on the yarn roller 7 perpendicular to yarn roller 7 is provided with several yarn outlet holes 9.
Yarn hole 8 is sent to be corresponding with a mover 4 and a yarn outlet hole 9 described in each.Yarn penetrates moving from sending yarn hole
Passed after son from yarn outlet hole, avoid yarn from knotting or wind, sent yarn hole and yarn outlet hole by setting, can further improve stator
The quantity of stator can be installed, yarn density is sent in raising, is prevented because yarn mutually winds and causes mechanism when sending yarn density too high on axle
Failure, further improve the operating efficiency of Yarn feeder.
The yarn hole 9 of sending for sending yarn hole 8 corresponding is preferably that central axis is collinearly set, and in order to avoid giving yarn hole 8
Yarn is caused to wear with yarn outlet hole 9, the excircle for sending the central axis of yarn hole 8 and the yarn outlet hole 9 and the mover 4
