Abstract
A wire cutting device of a sewing machine comprises a fixed base. The wire cutting device of the sewing machine is characterized in that: the wire cutting device further comprises a driving motor, a driving shaft which is equipped on the fixed base, and a blade which is equipped at a wire cutting end of the driving shaft; and the driving motor directly drives the driving shaft to be rotatably fixed at the driving shaft end. The wire cutting device of the sewing machine is advantageous in that: the driving motor is directly fixed with the driving shaft, thereby simplifying an original wire cutting structure, reducing assembling difficulty and manufacturing cost; 2. the driving shaft is driven to rotate through controlling the driving electrode, the wire cutting motion is quicker, and the driving shaft can be automatically reset through a self spring when wire cutting is stopped, not only is use facilitated, but also the mounting time is greatly reduced, thereby improving production efficiency; and 3. simple structure and facilitated maintenance are obtained, and market popularization is facilitated.
Description
[technical field]
The utility model relates to Sewing machines and makes the field, relates to a kind of thread cutting device of Sewing machines in particular.
[background technology]
At present, Sewing machines in process of production, in order to enhance productivity; Thread cutting device generally all is installed on Sewing machines, however the general complex structure all of existing thread cutting device, and it is through after installing a plurality of transmission mechanisms; Just can reach the cutting action that drives blade; Not only bad for operation and installation, and install also and quite waste time and energy, be unfavorable for safeguarding and using.
Therefore, the utility model provides a kind of thread cutting device of novel Sewing machines to the prior art deficiency.
[utility model content]
The purpose of the utility model provides a kind of simple in structure, the thread cutting device of the Sewing machines of being convenient to manipulate.
To above-mentioned purpose, the utility model adopts following technical scheme:
A kind of thread cutting device of Sewing machines; Include holder; It is characterized in that also including drive motors and be arranged on driving shaft and device on the holder at the blade of driving shaft tangent line end, said drive motors is fixed on driving shaft one end, drives the driving shaft rotation.
The thread cutting device of aforesaid a kind of Sewing machines is characterized in that said drive motors is provided with triangle fixed plate, and said drive motors is fixed by triangle fixed plate and holder.
The thread cutting device of aforesaid a kind of Sewing machines; It is characterized in that said holder is provided with fixed station; On fixed station, be provided with the fixing hole of fixed drive axle, said driving shaft is rotatable to be penetrated in fixing hole, and on driving shaft, is with back-moving spring; One end of said back-moving spring is limited in the fixing hole, and the other end is limited on the driving shaft.
The thread cutting device of aforesaid a kind of Sewing machines is characterized in that said fixed seating is provided with in a side of blade and is convenient to the trimming groove that blade is done cutting movement.
The beneficial effect of the utility model has: 1, drive electrode is directly fixed with driving shaft, simplified original line cutting structure, help reducing and assemble difficulty and manufacturing cost; 2, drive the driving shaft rotation through the control drive electrode, thread cutting action is quick more, can automatically reset through self spring when stopping trimming, and not only convenient the use also significantly reduced the set-up time, thereby enhanced productivity; 3, simple in structure, safeguard conveniently, help marketing and use.
[description of drawings]
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated;
Fig. 1 is the utility model stereogram;
Fig. 2 is the utility model vertical view;
