Description
Technical field
The utility model relate to industrial in the governor motion of last feed mechanism of thick stuff sewing machine, particularly a kind of last feed mechanism that makes compound feed sewing machine has differential feed to be formed the upper strata sewing to contract seam and can regulate this and contract and stitch and the differential seam governor motion of the compound feed sewing machine of releasing contraction joint function.
Background technology
Referring to Fig. 1, the last feed mechanism of the compound feed sewing machine of thick material comprises swinging axle 13 in general traditional, be fixed with crank 21 and presser feet wobble crank 12 at pads swing axis 13 two ends, crank connecting link 17 1 ends are fixedlyed connected with crank 21, the other end of crank connecting link 17 is fixedlyed connected with cloth feeding crank 22, presser feet wobble crank 12 is connected with change crank 14, and change crank 14 is connected presser feet outside the bottom of presser feet connecting rod II 3 is fixed with by presser feet connecting rod I 16 with presser feet connecting rod II 3.And interior presser feet is fixed on the compressor arm, moves mutually with outer presser feet.The crank amplitude of oscillation that crank connecting link 17 passes out, the transmission by pads swing axis 13, presser feet wobble crank 12, presser feet connecting rod I 16, presser feet connecting rod II 3 is delivered on the outer presser feet, by outer presser feet and the synchronous feeding of feed dog.As can be seen from Figure 1, the cloth feed amount of the last feed mechanism of conventional composite feed sewing machine can only be finely tuned on presser feet wobble crank 12, can't make sewing produce fold at all.And the crank 21 of this mechanism is fixedlyed connected with crank connecting link 17, also can't regulate the arm of force length of crank 21.Therefore the cloth feed amount of the last feed mechanism of traditional compound feed sewing machine generally all equates with the cloth feed amount of down charging mechanism, can't sew the sewings with differential effect, can not satisfy the demand that market changes day by day of making.
In order to sew the sewings with differential effect, the applicant has invented " have differential feed mechanism on the Sewing machines of contraction joint function and use the last feeding of this mechanism mechanism of crumpling ", and has applied for Chinese invention patent.Referring to Fig. 2, in this patent application, last differential feed mechanism is installed in the left surface window of casing.The two ends of its pads swing axis 13 are installed with crank 21 and presser feet wobble crank 12 by screw, and pads swing axis 13 drives crank 21 and 12 swings of presser feet wobble crank synchronously; On cloth pushing shaft 23, be installed with cloth feeding crank 22 and crank of tooth frame 24 by screw, cloth pushing shaft 23 drives cloth feeding crank 22 and crank of tooth frame 24 swings synchronously, crank of tooth frame 24 drives feed dog by retainer 25 and seesaws, and the feed dog in the needle plate 7 is realized the feeding of lower floor's sewing.
Crank 21 has a prong 26, one slide block 20 slidably is installed in prong 26, slide block 20 is connected with the upper end of crank connecting link 17 by an axial screw 19, and the lower end of crank connecting link 17 is connected with cloth feeding crank 22, and cloth feeding crank 22 drives crank connecting link 17 and swings synchronously.
Presser feet wobble crank 12 is connected with the end of presser feet connecting rod I 16 by change crank 14, and the other end of presser feet connecting rod I 16 is connected with presser feet connecting rod II 3, presser feet 2 outside being fixed with on presser feet connecting rod II 3.Drive the swing of regulating fork axle 11 by regulating, the adjusting fork axle 11 of swing drives crank connecting link 17 by connecting rod I 18 and swings, make slide block 20 produce displacement simultaneously, make the position of slide block 20 in the prong 26 of crank 21 change, therefore tie point to the length of the swing arm of force that constitutes between pads swing axis 13 central axis also will change thereupon between crank connecting link 17 and the slide block 20, elongated or shorten, the arm of force length that cloth feeding crank 22 is passed out changes the arm of force length of crank 21 by the slip of slide block 20, thereby change the pendulum angle of pads swing axis 13, again by presser feet wobble crank 12, change crank 14, presser feet connecting rod I 16, the transmission of presser feet connecting rod II 3, the cloth feed amount of outer presser feet 2 is increased thereupon or reduce, reach the effect of differential contraction joint.
But the above-mentioned differential feed mechanism of going up lacks a recovery mechanism, can't part do not need to contract seam or ordinary sewing or when backstitching arranged, make slide block arbitrary in the crank prong contract seam position moment return to the origin-location, realize part do not need to contract seam or ordinary sewing or backstitch.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of to be had contraction joint function and can regulate the contract differential seam governor motion of compound feed sewing machine of seam of the contract differential amount of seam and releasing, to solve the existing in prior technology problem.
