Description
Technical field
The utility model has the presser feet attitude reference device about a kind of Sewing machines, refers to that a kind of and seam Sewing machines has the attitude reference device of the presser feet of cutting knife especially.
Background technology
Sewing machines is in order to make such as: the crotch of panties, pants is to bottom of s trouser leg part, the Sewing machines provided at present is just equipped with can at the pressure bar of the cantilevered distal end knee-action of Sewing machines, and the presser feets possessing two pressure toes arranged along object to be sewn direction of feed and form have been installed in the lower end of pressure bar, and laterally install fixing cut-off knife at two pressure toes respectively, and can make relative to fixing cut-off knife the movable cut-off knife back and forth relatively cutting action by the reciprocal driving of driving mechanism.When the both sides of monolithic or two panels object to be sewn are along two the pressure toes of direction of feed through presser feet, the both sides of object to be sewn are incorporated in together, and after being cropped neat of fixing cut-off knife and movable cut-off knife, then the suture being through suture needle sewed up.
Because movable cut-off knife is to the distance of shaft centers of pressure bar from longer, add the strength that driving mechanism driving activity cut-off knife produces when relatively cutting action relative to fixing cut-off knife, very large reciprocating rotation moment can be produced to the axle center of pressure bar, depend merely on screw attempt and presser feet is locked securely can not to accomplish at pressure bar.Be will inevitably produce vibrations with presser feet, gently then cause seam mark to be distorted, heavy then cause presser feet to twist off suture needle.
In order to solve the above problems, No. I395851st, TaiWan, China patent of invention " press device of Sewing machines ", it comprises: pressing piece, is the lower end being installed on the pressing bar hung down from the end of sewing machine arm, and clamps tailoring cloth between the needle plate being arranged at sewing support; Cut-off knife mechanism, possesses movable cut-off knife, is arranged at this pressing piece (" presser feet " that be namely commonly called as), and moves back and forth in the direction that the direction of feed with this tailoring cloth is intersected; And fixing cut-off knife, and this movable cut-off knife slips; And vibration isolation member, be installed on this sewing machine arm, and abut from the rear side of this direction of feed and a part for this pressing piece, and suppress this pressing piece to the vibration of the both sides of the moving direction of this movable cut-off knife.Above-mentioned vibration isolation member has the 1st, the 2nd bearing surface, and it tilts each other inversely in the mode making the upstream side of this direction of feed and open, and and the different position of this pressing piece abut.Described vibration isolation member possesses pedestal, and this pedestal is fixed on the end of this sewing machine arm; 1st support member, is installed on this pedestal with changing position, and has the 1st bearing surface; And the 2nd support member, be installed on this pedestal with changing position, and there is the 2nd bearing surface.
The vibration isolation member that No. I395851st, TaiWan, China patent of invention possesses pedestal and the 1st, the 2nd support member, and the 1st, the 2nd support member can adjust position to pedestal in the scope in fixing hole and the gap between fixing hole and each fixed screw.The open type fixing hole of the 1st support member also cannot determine position with through bolt is wherein valid.
But, because sewing operation is complicated, must run into and change the problem such as new master's cut-off knife, broken string removing, the 1st support member must be pulled down separately, in order to dismounting pressing piece.
Although the vibration isolation member that No. I395851st, TaiWan, China patent of invention, its fixing hole being arranged at the holding flange of the 1st support member has the notch geometry of the right edge opening to this holding flange.Therefore, the 1st support member, after unclamping the fixed screw through fixing hole, makes holding flange to the slip of tossing about of the opening of fixing hole, whereby, can extract to the front of sewing machine arm and pull down under still fixed pedestal.But when being installed on according to contrary step the pedestal being fixed on sewing machine arm, the 1st bearing surface of the 1st support member but cannot accurately abut with the face of touching of the left rear side of pressing piece body once again.Still need to be dependent on the adjustment of well-trained maintenance personal precision, otherwise vibration isolation member still cannot play due vibration-isolating effect, still desirable not to the utmost.
In order to thoroughly solve the problem of No. I395851st, above-mentioned TaiWan, China patent of invention, the utility model is intended to the presser feet attitude reference device providing a kind of Sewing machines.
