Abstract
The utility model relates to a sewing machine, in particular to a presser foot mechanism of a sewing machine. A presser foot base and a presser foot plate are connected through a hinged base and a fastening rotating shaft. The presser foot mechanism is simple in structure, the hinged base is additionally arranged between the presser foot base and the presser foot plate, the hinged base guarantees adjustment of a distance between the front and the rear of the presser foot plate, simultaneously when sewing label fabric with different thickness, the bottom surface of the presser foot plate and the label fabric can contact with each other completely only by screwing out a nut on a stud shaft and adjusting the size of an elevation angle of the presser foot plate, and then the presser foot plate is fixed by fastening nuts. Besides, an elastic layer is additionally arranged on the bottom surface of the presser foot plate to increase friction coefficient between the presser foot plate and the label fabric, thereby guaranteeing the label fabric not to slide and move relatively.
Description
One, technical field:
The utility model relates to Sewing machines, particularly its presser foot device.
Two, background technology:
The label of many clothes or other fabrics is convenient to dismantle afterwards for the consumer buys back, and does not damage fabric again, adopts chain-type stitch nail seam more, just can transfer suture as long as this chain-type stitch is chosen a end of a thread.The most button attaching machines that use of existing nail price labeling repack into, its presser foot as shown in Figure 1, usually the thickness of label fabric is that 4-5mm does not wait, the presser foot of existing nail price labeling exists the phenomenon as Fig. 2, be that pressure foot can not contact fully with the label fabric, the label fabric is easy to generate slippage in the work feed motion, causes situations such as bouncing pilotage, broken needle.Presser feet of the present invention such as Fig. 3, pressure foot is fastened on the presser feet seat with screw, and presser feet seat and work feed underframe are hinged, clamp the label fabric with the presser feet base plate under the effect of spring, guarantee that the label fabric moves with pressure foot and presser feet base plate in the work feed process.
Three, summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of presser foot device of Sewing machines is provided, and is simple in structure, can both guarantee that to the fabric of different-thickness the bottom surface of pressure foot contacts fully with it, and another purpose is to guarantee that relative slippage does not take place fabric.
The technical scheme that the utility model is adopted for achieving the above object is: be connected by hinged seat and fastening turning cylinder between a kind of presser foot device of Sewing machines, presser feet seat and pressure foot.
Described fastening turning cylinder is the nut that is threaded on the bolt shaft, and pressure foot axis hole and hinged seat axis hole connect by fastening turning cylinder.
Described pressure foot bottom surface is fixed with elastic layer.
Described elastic layer is the elastic polyurethane layer.
The utility model presser foot device is simple in structure, between presser feet seat and pressure foot, add a hinged seat, hinged seat guarantees the adjustment of pressure foot longitudinal separation, while is for the label fabric of sewing different-thickness, as long as unclamp the nut on the bolt shaft, by regulating the elevation angle size of pressure foot, just can make the bottom surface of pressure foot contact (Fig. 4) fully, then clamp nut fixing presser foot plate with the label fabric.In order to increase the coefficient of friction between pressure foot and the label fabric, on the bottom surface of pressure foot, added one deck elastic layer in addition, guaranteed that more relative slippage does not take place the label fabric.
Four, description of drawings:
Fig. 1 is the presser foot schematic diagram of existing nail price labeling.
Fig. 2 is the schematic diagram that existing nail price labeling pressure foot compresses the label fabric.
Fig. 3 is the presser foot schematic diagram that the present invention follows closely price labeling.
Fig. 4 is that the present invention follows closely the schematic diagram that the price labeling pressure foot compresses the label fabric.
Five, the specific embodiment:
The presser foot device of a kind of Sewing machines as shown in Figure 3, presser feet base plate 9 is fixed on the front end of feed mechanism work feed underframe 1, be connected with fastening turning cylinder by a hinged seat 7 between presser feet seat 3 and the pressure foot 8, hinged seat 7 is fixed on the presser feet seat 3 by front and back adjustment screw 2, fastening turning cylinder is the nut 5 that is threaded on the bolt shaft 6, and pressure foot 8 axis holes and hinged seat 3 axis holes connect by fastening turning cylinder.Presser feet seat 3 is hinged by bearing pin 11 and feed mechanism, clamps label fabric 10 with presser feet base plate 9 under the effect of spring 4, guarantees that label fabric 10 moves with pressure foot 8 and presser feet base plate 9 in the work feed process.In order to increase the coefficient of friction between pressure foot 8 and the label fabric, on the bottom surface of pressure foot 8, added one deck polyurethane material elastic layer, guarantee that more relative slippage does not take place label fabric 10.
During use, for the label fabric of different-thickness, as long as unclamp nut 5 on the bolt shaft 6, by regulating the elevation angle size of pressure foot 8, make the bottom surface of pressure foot 8 contact (Fig. 4) fully with label fabric 10, clamp nut 5 then.
