The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, employed universal dribbling presser feet on the special embroidery machine of this dribbling, comprise presser feet seat 1, be fixedly connected with guide rail 4 by second screw 8 on the described presser feet seat 1, be fixedly connected with bearing block 10 on the centre position of guide rail 4, left slider 3, right slide block 9 are separately positioned on two sides of bearing block 10 and are with guide rail 4 respectively and be slidingly matched; In a side parallel with guide rail 4 a bidirectional modulation screw rod 2 is installed, this bidirectional modulation screw rod 2 is installed in left slider 3, bearing block 10 and the right slide block 9; The centre of bidirectional modulation screw rod 2 has V-type groove 2-1, and left slider 3 and right slide block 9 are that fulcrum is symmetrical arranged with V-type groove 2-1; The left hand thread that is threaded engagement with left slider 3 is adopted in the left side of V-type groove 2-1, and the right-handed thread that is threaded engagement with right slide block 9 is adopted on the right side; Nibbed screw 7 passes bearing block 10 and corresponding with V-type groove 2-1.Be fixedly connected with spring leaf 5 by first screw 6 on the described presser feet seat 1, one of spring leaf 5 is rectified for the gap between left slider 3, the right slide block 9.
Operation principle: 1, form the gap of a rectangle between left slider 3, right slide block 9 and the guide rail 4, left slider 3 and right slide block 9 can horizontally slip on guide rail 4 neatly, and when left slider 3 and right slide block 9 slided toward central point, the rectangle width reduced; Left slider 3 and right slide block 9 is toward away from central slide, and it is big that the rectangle width just becomes, and plays the purpose that increases or reduce the rectangle width on a horizontal linear.2, designed right-and-left threaded screw-rod structure.With the central point is symmetry, the right side screw rod of right-handed thread, the left side is with the screw rod of left hand thread, like this when bidirectional modulation screw rod 2 is done rotation, left slider 3, right slide block 9 just can slide relatively, and bidirectional modulation screw rod 2 has just play a part between control left slider 3, the right slide block 9 like this.When screw rod rotated, left slider 3, right slide block 9 can slide along bidirectional modulation screw rod 2 directions, and the size of slip is by the pitch of the internal thread in bidirectional modulation screw rod 2 and the bidirectional modulation screw rod 2 and the angle decision of screw rod rotation.3, nibbed screw 7 is not when screwing, and when the gap in about 0.1~0.2 millimeter scope was arranged, bidirectional modulation screw rod 2 can only be done rotation and move and can not move axially; After nibbed screw 7 screwed, bidirectional modulation screw rod 2 just was fixed on the bearing block 10, can not do any move, and had so just locked the position of left slider 3, right slide block 9, had also just locked the broadband width of dribbling presser feet, had solved the problem that width walks.4, screw rod central point location structure.On bidirectional modulation screw rod 2 symmetrical centre, have V-type groove 2-1, the middle part of bidirectional modulation screw rod 2 rotates in bearing block 10, nibbed screw 7 inserts in the V-type groove 2-1 of bidirectional modulation screw rod 2, make bidirectional modulation screw rod 2 can only on circumference, do to rotate and can not axially move, if left slider 3,9 two slide blocks of right slide block rotate bidirectional modulation screw rod 2 in the adjustment so that initial assembling is a symmetry like this, make the distance between two slide blocks increase or reduce, keep two slide blocks to the distance of central point is identical size always, i.e. the center symmetry.
The course of work as shown in the figure, general presser feet seat 1 is fixed on the embroidery machine when using, unscrew 7 about 1/4th weeks of nibbed screw, operate on rotation bidirectional modulation screw rod 2 with a word, left slider 3 and right slide block 9 are done to moving in the other direction along guide rail 4, to adjust the middle space distance of presser feet, slightly wideer 0.5 millimeter than ribbon, screw nibbed screw 7, i.e. adjustment finishes.Wherein 4 second screws 8 are fastened on guide rail 4 on the general presser feet seat 1, and first screw 6 is fastened on spring leaf 5 on the general presser feet seat 1, pushes down ribbon, makes ribbon play the effect of stablizing ribbon in shifting out process.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
