Abstract
An adjustable transmission structure of multi-needle tailor tacking machine belongs to the technical field of tailor tacking machinery, and in particular refers to a transmission structure for multi-needle rotating shuttle tailor tacking machine with high tailor tacking efficiency and large stitch density. The utility model is realized through the following technical proposal: transmission shaft is connected with synchronous belt pulley via synchronous belt; one end of output shaft of the synchronous belt pulley is fixed with cam; the cam has eccentric rail groove with special-shaped round end surface; intermediate swing arm shaft seat is fixed on machine frame; intermediate swing arm installed on the intermediate swing arm shaft seat in swing manner has pulley disposed at its one end and extending into the eccentric rail groove of the cam, and the other end hinged to small link rod; and the other end of the small link rod is hinged to thread toggle swing arm fixed on thread toggle shaft. Since the pulley extends into the eccentric rail groove with special-shaped round end surface, as long as the eccentric rail groove can satisfy movement trail of the pulley, rotating shuttle requirement of fast needle-in and slow needle-out can be realized via the thread toggle shaft. Furthermore, by regulating starting position of the pulley in the eccentric rail groove, corresponding parameters can be conveniently adjusted to solve problems during change of stitch size.
Description
Technical field:
The utility model relates to the quilting field of mechanical technique, refers in particular to the drive mechanism of a kind of quilting efficient height, spininess rotating shuttle quilting machines that stitch density is big.
Background technology:
At present, existing have the shuttle quilting machines in the process of quilting, all is that eedle is done vertical motion on frame, and peg or spindle is then made horizontal reciprocating movement on frame, thereby realize its quilting action.Study carefully its action, the main cause of restriction quilting speed, quality has:
1, make horizontal reciprocating movement on frame, if improve the horizontal reciprocating movement speed of peg or spindle, the movement inertia of peg or spindle then can cause the noise of frame to increase, and entire machine produces vibrations;
2, because quilting speed is low, and the pin number of unit interval door quilting is few, and the stitch of quilting is big, cause using the quilting pin of ting model, the product quality that quilting goes out is not high, is difficult to reach the effect of machine embroidery.
3, if need to change the size of stitch, then require to change the eccentric cam on the power transmission shaft, adjust relevant parameter it is complementary with it, this is the comparatively work of trouble.
In order to solve above-mentioned problem, the inventor has proposed to do on frame with the replacement of rotation peg or spindle the peg or spindle of horizontal reciprocating movement in " spininess rotating shuttle quilting machines " utility model patent of 200520060504.9, improved quilting speed widely, reduced noise, quilting goes out the effect of machine embroidery.Yet, in use also find, because original the drive mechanism of shuttle quilting machines is arranged is to drive eccentric cam by power transmission shaft, pass motion to thread toggle shaft by transmission mechanisms such as connecting rods again, make eedle under the swing of thread toggle shaft, on frame, do vertical motion; This kind drive mechanism, can't satisfy inserting needle fast, go out the slow rotating shuttle requirement of pin.
Summary of the invention:
The purpose of this utility model is overcoming above-mentioned problems of the prior art, and provide a kind of can satisfy inserting needle fast, go out the slow rotating shuttle of pin and require, can when stitch changes, adjust the adjustable drive mechanism of multi-needle quilter of relevant parameter easily.
The utility model is achieved by the following technical solution: power transmission shaft is connected with synchronous pulley by being with synchronously, one end of synchronous pulley output shaft is fixed with cam, described cam is that end face is the eccentric orbit groove of abnormity circle, middle swing arm axle bed is fixed on the frame, the pulley of the middle swing arm one end of swing arm axle bed protrudes out in end face is the cam of the round eccentric orbit groove of abnormity in the middle of being installed in swingably, its other end and small rod are hinged, and to dial swing arm hinged with being fixed on line on the thread toggle shaft for the other end of small rod.
The utility model, just can be realized that inserting needle is fast, go out the slow rotating shuttle requirement of pin by thread toggle shaft so long as the eccentric orbit groove of abnormity circle can satisfy the movement locus of pulley because pulley protrudes out in end face is the eccentric orbit groove of abnormity circle; And is the original position of the eccentric orbit groove of abnormity circle by adjusting pulley at end face, just can adjust relevant parameter easily, and the problem that is faced when solving change stitch big or small has advantage simple in structure, easy to operate.
Description of drawings:
Accompanying drawing 1 is the utility model front view
Accompanying drawing 2 is the utility model structural representation
Accompanying drawing 3 is one of the utility model schematic diagram of movements
Accompanying drawing 4 is two of the utility model schematic diagram of movements
The specific embodiment:
See accompanying drawing 1～2, power transmission shaft 2 is connected with synchronous pulley 3 by being with synchronously, one end of synchronous pulley 3 output shafts is fixed with cam 4, described cam 4 is the eccentric orbit groove 41 of abnormity circle for end face, middle swing arm axle bed 8 is fixed on the frame 1, the pulley 51 of the middle swing arm 5 one ends of swing arm axle bed 8 protrudes out in end face is the cam 4 of the round eccentric orbit groove 41 of abnormity in the middle of being installed in swingably, its other end and small rod 7 are hinged, and to dial swing arm 91 hinged with being fixed on line on the thread toggle shaft 9 for the other end of small rod 7.
See accompanying drawing 1～4, when using the utility model, if driven by motor power transmission shaft 2 rotates, power transmission shaft 2 rotates by the synchronous pulley of band drive synchronously 3, make an end of synchronous pulley 3 output shafts be fixed with cam 4 rotations, protruding out pulley 4 in end face is the cam 4 of eccentric orbit groove 41 of abnormity circle retrains along with eccentric orbit groove 41 and moves, thereby make the middle swing arm 5 that is installed in middle swing arm axle bed 8 swingably that wobbling actions take place, its other end also drives the small rod hinged with it 7 actions, small rod 7 is dialled swing arm 91 by line makes thread toggle shaft 9 produce reciprocating motion around its axis, and then make the eedle 6 on the thread toggle shaft 9 do reciprocal vertical motion, because the eccentric orbit groove 41 of abnormity circle is for designing in advance, just can control eedle 6 during operation is easily advancing, go out speed different in the process, thereby finish the requirement of the rotating shuttle course of work easily.
If need to change the variation of stitch, then only need unload the synchronous band that connects between power transmission shaft 2 and the synchronous pulley 3, adjust the deflection angle of cam 4 by its mutual initial position, that is adjustment pulley 51 is the original position of the eccentric orbit groove 41 of abnormity circle at end face, just can adjust relevant parameter easily, obtain required stitch size.
