Description

The concealed thread cutter of sewing machine

Technical field

This utility model is the concealed thread cutter about a kind of sewing machine, espespecially a kind of action machine Structure does not exposes, and the thread cutter of discontinuous action.

Background technology

It is applied to the thread cutter of sewing machine at present, just like utility model patent the M481242nd " bag The suture Scissoring device of suture needle car ", it is provided with one group of riser, is fixed on the board of overseam sewing machine, This group riser is provided with pushing tow power source, and makes the power transmission shaft of this pushing tow power source with movable knife bar even Connect, and device one fixes knife plate on this group riser, make this activity knife bar and the blade of fixing knife plate Portion is corresponding, is separately provided with a folder in this group riser and pulls platform, and be provided with a covering, is covered in this work Above the blade part of moving knife bar, separately in this covering edge forming one suture positioning port, make this suture fixed Position mouth is positioned at the blade part joint with this activity knife bar and fixing knife plate.

Above-mentioned existing Scissoring device, operator is after the complete working substance of sewing, it is necessary to drawn by suture Causing covering suture positioning port, now, pushing tow power source receives signal and drives this connecting rod, to push away Dynamic movable knife bar, and make the blade part blade part direction displacement towards fixing knife plate of this activity knife bar, With by suture severing, and this suture is made to separate with sewing working substance.

But above-mentioned operation, operator must be fixed to hiding suture by suture pull with freehand manner Position mouth, therefore operator must stop sewing work, and makes sewing job interruption；It addition, this use With mechanisms such as the pushing tow power source of linkage activity knife bar and connecting rods thereof, be exposed to outside, operator exists Free-hand pull by suture is easily collided with these mechanisms during hiding suture positioning port, causes Injured, also aobvious necessity having improvement.

In view of this present inventor, adds and gives research and innovation, discloses hiding of this utility model sewing machine Formula thread cutter.

Utility model content

Technical problem underlying to be solved in the utility model is, overcome that prior art exists is upper Stating defect, and provide the concealed thread cutter of a kind of sewing machine, it is that actuating mechanism does not exposes, And the thread cutter of discontinuous action.

This utility model solves its technical problem and be the technical scheme is that

A kind of concealed thread cutter of sewing machine, including: a body, containing a suction tube portion, The end making this suction tube portion is connected a convulsion assembly, and makes the front end in this suction tube portion contain a suction Mouthful, and at this suction inlet, it is provided with a tool rest, so that extraneous suture is sucked this suction inlet, and it is cross-placed on On this tool rest；One support body, interlocking, between the housing of this body and this sewing machine, makes this body and is somebody's turn to do Between the housing of sewing machine, define formation one accommodation space；One knife plate, is installed in this with a rotating shaft On body, and it is resisted against the side of this tool rest, makes this knife plate contain a blade portion, swing with this knife plate The sliding lateral margin through this tool rest in ground；One action component, interlocking in this accommodation space, this action component Containing an actuating strut, this actuating strut is made to be pivoted this knife plate；And a sensor, in order to sense sewing When working substance will leave the Xia Zhen district of sewing machine, just trigger a signal, to drive this action component Actuating strut link this knife plate pivot joint pivot according to this knife plate and this body, be positioned at this to cut off Suture between blade portion and this tool rest.

The concealed thread cutter of sewing machine disclosed in this utility model, owing to this action component is lock It is connected to the inner side of this body, and is hidden in this accommodation space, make this utility model in order to stir this The mechanism of knife plate, is hidden between this body and sewing machine housing in the accommodation space constituted fortune totally Dynamic, owing to being stopped by this body, therefore the hand of operator or sewing working substance, just will not By rapid movement action component and link gear wounded or be involved in, exist promoting sewing machine Operational safety.

The concealed thread cutter of sewing machine disclosed in this utility model, after working substance sewing completes, The suture formed at tail end can be inhaled in this suction inlet automatically, and is cross-placed on this tool rest, therefore Being not required to operator carry out with freehand manner, just can automatically carry out tangent line work, therefore operator is also Need not stop sewing work, can directly carry out the sewing operation of subsequent work part, to promote work Efficiency.

It addition, the concealed thread cutter of sewing machine disclosed in this utility model, owing to this knife plate exists During sewing, the most continuously move, and accept the signal of this sensor and move, Therefore the number of times that slip over this tool rest can be greatly decreased, reduce the rate of wear of the blade portion of this knife plate, Make this utility model that the service life of this knife plate can be substantially improved, and show excellence of the present utility model Property.

The beneficial effects of the utility model are, it is that actuating mechanism does not exposes, and discontinuous action Thread cutter.
