Description
Technical field
the invention belongs to technical field of sewing equipment, relate to the transmission device of a kind of Sewing machines, particularly a kind of sewing-machine foot.
Background technology
sewing machines is to use one or more sewing thread, forms one or more stitchings on sewing, the machine that makes one or more layers sewing interweave or unite by a seam.Sewing function is made the goods such as the fabrics such as cotton, fiber crops, silk, hair, artificial fibre and leather, plastics, paper, the stitching neat appearance of stitching out, smooth firm, and sewing velocity is fast, easy to use.Presser feet is the very important parts in Sewing machines, play the effect of pushing down sewing cloth, this presser feet needs again regular making to lift and put down action in the process of sewing action, therefore needs a kind of special drive unit to drive this presser feet work.
a kind of mechanism for lifting pressre of sewing machine as disclosed in patent (CN200520014626.4) in prior art, comprise presser foot lifter lobe plate, be located at the intermediate gearing between presser foot lifter lobe plate and presser feet, intermediate gearing comprises the pull bar of a horizontally set, between pull bar and presser foot lifter lobe plate, be provided with one and rotate the first drive mechanism that presser foot lifter lobe plate can cause pull bar translation, between pull bar and presser feet, be provided with one and can drive by pull bar translation the second drive mechanism moving on presser feet.This mechanism for lifting pressre of sewing machine action is light, can make presser feet realize rapidly ascending, descending action, and service speed is fast.
but the device in this patent also exists that the parts that pull bar connects are too much, the first drive mechanism and the second drive mechanism all rely on the driving of pull bar, cause the structure of pull bar and required precision too complicated, easily the defect such as damage.
Summary of the invention
the object of the invention is the problems referred to above that exist for existing technology, a kind of transmission device of sewing-machine foot is provided, its technical problem to be solved is: how to simplify the function of single connecting rod, structural design is simplified, structure good operation stability.
object of the present invention can realize by following technical proposal:
a kind of transmission device of sewing-machine foot, Sewing machines comprises casing, presser feet and fixed bar one, described fixed bar one is plugged on casing and casing slip relatively vertically, the bottom of described presser feet and fixed bar one is connected, it is characterized in that, this transmission device comprises master connecting-rod, slave connecting rod, main crank one and main crank two, the middle part of described main crank one is hinged on described casing, the middle part of the outer end of described main crank one and described fixed bar one is hinged, the inner of this main crank one and the outer end of described master connecting-rod are hinged, the inner of described main crank two is hinged on described casing, the outer end of described main crank two and the inner of described master connecting-rod is hinged and be provided with the slide construction that can make this pin joint skew predeterminable range between the two, between described main crank two and casing, be provided with the drives structure one that can intermittently drive this main crank two to swing around inner pin joint, between the inner of described slave connecting rod and casing, be provided with and can drive this slave connecting rod to produce the drives structure two moving inward, between the outer end of described slave connecting rod and described master connecting-rod middle part, be provided with the transmission component that can make slave connecting rod drive master connecting-rod to move inward.
its principle is as follows: the action of the presser feet of Sewing machines be generally comprise one section of continuous lifting depress action and once in a while once lift action, continuous lifting depressed the action decorative pattern that is mainly used for sewing, the action of lifting is once mainly used for tangent line once in a while, and the object of two kinds of actions is completely different.Drives structure one in this transmission device intermittently drives main crank two rotations, main crank two drives master connecting-rod translation, master connecting-rod drives main crank one to rotate, main crank one drives fixed bar one to move up along axis direction, thereby drive presser feet to lift action, because drives structure one is intermittently to drive, presser feet is done and lifted action regular intermittence, realize one section of continuous lifting saying above and depress action.Drives structure two in this transmission device can drive slave connecting rod translation in needs, slave connecting rod drives master connecting-rod translation by transmission component, master connecting-rod drives fixed bar one to make presser feet lift action, owing to there is slide construction between the outer end of main crank two and the inner of master connecting-rod, when master connecting-rod is driven by slave connecting rod and main crank two do not interfere.The scheme of two connecting rods of the creationary employing of this transmission device, be responsible for respectively two kinds of difference in functionalitys presser feet lift action, make each connecting rod function singleness, make drives structure design simplification, drives structure good operation stability.
