More neatly beautiful.
Employ the following technical solutions for achieving the above object：
A kind of cutting knife system of sewing machine it is characterised in that：Including motor, electric rotating machine, drive mechanism and circle
Knife, described drive mechanism includes upper box and lower box, and described dise knife is fixed on the end of a horizontal rotating shaft, horizontal rotating shaft
It is arranged in nowel body by bearing, in top box body, be provided with drive shaft and rotary sleeve, rotary sleeve lower end and lower box
It is connected, drive shaft lower end is connected with horizontal rotating shaft by umbrella tooth；The outfan of described electric rotating machine is engaged with rotary sleeve,
The outfan of described motor is connected with drive shaft.
Described motor and electric rotating machine are separately fixed at upper box top and sidepiece, described drive shaft and rotation
Rotating shaft set is vertically arranged with, and drive shaft is placed in rotary sleeve by bearing, and the upper end of drive shaft is defeated with motor
Go out end to be connected, the lower end of drive shaft is passed through the cooperation of umbrella tooth and is connected with horizontal rotating shaft.
It is fixed in top box body by bearing in the middle part of described rotary sleeve, rotary sleeve lower end is connected with lower box, rotation
The upper socket of rotating shaft set is meshed with the worm screw of electric rotating machine outfan in rotary teeth, rotary teeth.
Described upper box is passed through elevating mechanism and is connected with fixed plate, and cutting knife system is fixed on sewing machine machine by fixed plate
On head.
This utility model is cut by dise knife high-speed rotation, without bottom knife cooperation, with respect to existing cutting
Knife structure is simpler, and dise knife rotation cuts goes up down cut relatively, and sheared edge is more neat, is not likely to produce burr.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is side portion structure schematic diagram of the present utility model；
Fig. 3 is for A-A in Fig. 2 of the present utility model to sectional view.
Specific embodiment
As Figure 1-3, the cutting knife system of a kind of sewing machine, including fixed plate 1, motor 2, electric rotating machine 3, passes
Motivation structure and dise knife 7, described drive mechanism includes upper box 5 and lower box 6, described upper box 5 pass through elevating mechanism 8 with
Fixed plate 1 is connected, and cutting knife system is fixed on head of sewing machine fixed plate 1；Described dise knife 7 is fixed on a horizontal rotating shaft
61 end, horizontal rotating shaft 61 is arranged in lower box 6 by bearing, is provided with drive shaft 51 and rotary shaft in upper box 5
Set 52, rotary sleeve 52 lower end is connected with lower box, and drive shaft 51 lower end is connected with horizontal rotating shaft 61 by umbrella tooth；Described
The outfan of electric rotating machine 3 is meshed with rotary sleeve 52, and the described outfan of motor 51 is connected with drive shaft 51.
Described motor 2 and electric rotating machine 3 are separately fixed at upper box 5 top and sidepiece, described drive shaft
51 and rotary sleeve 52 be vertically arranged with, drive shaft 51 is placed in rotary sleeve 52 by bearing, drive shaft 51 upper
End is connected with motor 2 outfan, and the lower end of drive shaft 51 is passed through the cooperation of umbrella tooth and is connected with horizontal rotating shaft 61；Described rotation
Rotating shaft set 52 middle part is fixed in upper box 5 by bearing, and rotary sleeve 52 lower end is connected with lower box 6, rotary sleeve 52
Upper socket is meshed with the worm screw 31 of electric rotating machine 3 outfan, is provided with above rotary teeth 53 in rotary teeth 53, rotary teeth 53
Trim ring 55, trim ring 55 is screwed in rotary sleeve 52 top, and rotary teeth 53 is fixing.
During utility model works, declined by elevating mechanism 8 and enable dise knife 7 to be cropped to fabric, motor 2 passes through
Drive shaft 51 is moved horizontal rotating shaft 61 through umbrella cingulum and then drives dise knife 7 high-speed rotation to carry out cutting fabric；Electric rotating machine passes through snail
Bar 31 and rotary teeth 53 coordinate drive rotary sleeve 52 to rotate, and rotary sleeve 52 rotation can drive lower box 6 integral-rotation, passes through
