Description
Technical field
The utility model relates to a kind of servicing unit for sewing-machine foot, is specially adapted to making of cladding.
Background technology
Existing Sewing machines is typically provided with presser feet, utilizes presser feet to carry out the compacting cloth, thereby carries out stable making.But during the making of more difficult fabric, particularly cladding, presser feet easily elongates and scratches cladding, will cause loss economically for some work feeds.Now also have and use the press strip of strip shape to be arranged on below presser feet, while making, press strip moves with fur clothing, with this, prevents that cladding is not elongated or damages, but this press strip limited length, when being sewn into while approaching the press strip end, just need again press strip be drawn back, draw back the rear position that at every turn all needs to adjust press strip, thereby operation inconvenience, labour intensity is large, inefficiency.
The applying date is on February 23rd, 2012, China Patent Publication No. 202440642U, a kind of adjustable contact roller presser feet of sewing machine is disclosed, it can reach does not change roller and can make roller press reach the different purposes of eating the cloth amount, although it is more convenient that roller press operates when making cladding,, roller press will be pressed into arc to cladding to be made, make suture inhomogeneous, affect attractive in appearance.
In sum, also do not have at present a kind of simple in structure, reasonable in design, dependable performance, easy to use, the servicing unit for sewing-machine foot of efficient work.
The utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, and easy to use, work feed is effective, makes the servicing unit for sewing-machine foot that process can sideslip.
The technical scheme in the invention for solving the above technical problem is: should be for the servicing unit of sewing-machine foot, comprise presser feet and presser bar, described presser feet is fixed on presser bar, it is characterized in that: also comprise trim ring installing mechanism and trim ring, the bottom of described trim ring installing mechanism is provided with brace, and described trim ring installing mechanism is fixed on presser bar by brace; Described trim ring is cirque structure; The top of described trim ring installing mechanism is provided with draw-in groove, and described trim ring installing mechanism is provided with the location snap fit, and described presser feet bottom is provided with groove; Described presser feet is pressed on the internal face of trim ring bottom, and the bottom of trim ring is positioned at the groove of presser feet, and described location snap fit hooks on the outside wall surface of trim ring, and described trim ring is engaged in the internal face that the interior and draw-in groove of draw-in groove is held trim ring, and described trim ring is made by elastomeric material.The present invention is simple in structure, reasonable in design; 3 on the same straight line can not determine a circle, so trim ring can position installation by draw-in groove, location snap fit and groove, and trim ring is free to rotate when stressed; Draw-in groove is held trim ring can prevent that trim ring is out of shape downwards, the location snap fit catches on trim ring, location snap fit beating and make restriction diametrically can rotate trim ring the time, presser feet is pushed down the bottom of trim ring, draw-in groove, location snap fit and groove make the rotation of trim ring more steadily reliable to the spacing of trim ring, and the movement locus of trim ring can not depart from; During work, trim ring is pressed on cladding, and due to the frictional force between trim ring and cladding, trim ring can rotate along with the charging of cladding, therefore can prevent that cladding is elongated or damages; Trim ring is made by elastomeric material, thereby when work, and trim ring is positioned at part under presser feet will pressurized and become smooth, make suture needle operation on the cladding of opposed flattened all the time, thereby cabling is more even; During shut-down operation, presser bar will lifting, because the trim ring installing mechanism is fixed on presser bar, the trim ring installing mechanism also will lifting, the draw-in groove that now is positioned at trim ring installing mechanism top will lift trim ring, and when needs are made, trim ring is directly pressed cladding with the decline of presser bar, without the position of readjusting trim ring, improved operating efficiency.
Trim ring installing mechanism described in the utility model comprises upper piece and lower piece, and described upper piece is provided with slotted hole, and described lower piece is located by connecting by slotted hole and lower piece.Draw-in groove is arranged on the top of upper piece, connecting portion and brace all are arranged on lower piece, lower piece can arrange some circular holes, by 2 rivets or 2 bolts, through slotted hole, be positioned in circular hole again, by the setting of slotted hole, make upper piece relative with lower piece adjustable, thereby make the position of draw-in groove adjustable, finally can realize the adjustment to trim ring, the trim ring that trim ring is adjusted to optimum position or adapts to different size with this.
Be provided with connecting portion on trim ring installing mechanism described in the utility model, location snap fit and connecting portion are hinged.Locator card was worked hard in glove with connecting portion and was connected on the trim ring installing mechanism, after location snap fit and connecting portion are hinged, the location snap fit can be rotated when applying external force, therefore can make trim ring in optimum position by the adjustment of location snap fit, and also can adapt to the trim ring of different size by the adjustment of location snap fit, enlarge the scope of application.
Location described in the utility model snap fit is brace to 1/5th to 1/2nd of the distance b at trim ring installing mechanism top to brace apart from a.Now locate the good positioning effect of snap fit to trim ring.
Upper piece described in the utility model and lower piece are elastomeric material and make.Because upper piece and lower piece are elastomeric material, make, the elastic deformation that with this, can adapt to trim ring, prevent that trim ring from coming off.
Presser feet described in the utility model is provided with the suture needle groove, and described groove is positioned at the side of suture needle groove.Thereby the position of trim ring can not have influence on the normal operation of suture needle.
The utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, because 3 on the same straight line can not determine a circle, therefore trim ring can position installation by draw-in groove, location snap fit and groove, and trim ring is free to rotate when stressed; Draw-in groove is held trim ring can prevent that trim ring is out of shape downwards, the location snap fit catches on trim ring, location snap fit beating and make restriction diametrically can rotate trim ring the time, presser feet is pushed down the bottom of trim ring, draw-in groove, location snap fit and groove make the rotation of trim ring more steadily reliable to the spacing of trim ring, and the movement locus of trim ring can not depart from; During work, trim ring can rotate along with the charging of cladding, therefore can prevent that cladding is elongated or damages, trim ring is made by elastomeric material, thereby when work, trim ring is positioned at part under presser feet will pressurized and become smooth, make suture needle operation on the cladding of opposed flattened all the time, thereby cabling is more even.
