Description
Technical field
Sewing machine technique field is the utility model is related to, more particularly to a kind of thread wrapping device for sewing machine.
Background technology
The bottom line coiling of sewing machine is rotated by machine spindle at present, assembles drive plate and rotating disk drives wire spool
So as to reach the coiling of bottom line, its miniature DC power of motor is 250W~750W, and needs manually to switch coiling for rotation
Device, for this device mode in sewing machine industry extensive use, its shortcoming is to need manpower craft frequent operation to switch.
Another Winder needs to install single-chip microcomputer, power switch in device case, tension disk, power interface, referred to
Show the parts such as lamp, potentiometer, although this device it is high can to install very cumbersome and Expenses Cost with automatic switch.
Therefore a kind of technical scheme is needed to solve the problems such as existing thread wrapping device for sewing machine cost is high, cumbersome for installation.
Utility model content
The purpose of this utility model is to provide a kind of thread wrapping device for sewing machine, multiple for solving installation in the prior art
Miscellaneous, the problems such as cost is high.
A kind of thread wrapping device for sewing machine of the utility model, it is characterised in that the thread wrapping device for sewing machine includes miniature DC
Motor, the miniature DC motors are connected with circuit board, and wire spool, the wire spool side dress are housed on the miniature DC electric machine main shafts
There is gear line bar.
Preferably, the circuit board includes time block, and the time block manipulates the miniature DC motor switch time.
From such scheme, a kind of thread wrapping device for sewing machine of the utility model, it is characterised in that thread wrapping device for sewing machine
Including miniature DC motors, miniature DC motors are connected with circuit board, wire spool are housed, wire spool side is equipped with gear line on DC electric machine main shafts
Bar.Circuit board includes time block, and time block manipulates the miniature DC motor switch time.The utility model patent is not required to assemble
Drive plate and rotating disk, it is not required that the portion such as installation single-chip microcomputer, power switch, tension disk, power interface, indicator lamp, potentiometer
Part, there is cost-effective, simple installation.
The characteristics of the utility model, see this case schema and the following preferably detailed description of embodiment and obtain clear
Ground understands.
