Abstract
The utility model relates to the technical field of quilting and embroidering, in particular to a take-up mechanism of a quilting machine and an embroidery machine, comprising a take-up axis and a power device; the main driving axis of the power device is fixed with an eccentric wheel; an eccentric auxiliary axis extends from the eccentric wheel; the end of the auxiliary axis is hinged with a composite connecting rod one end of which is hinged with an auxiliary rod; the other end of the auxiliary rod is hinged with the swinging arm extending from the take-up axis; the composite connecting rod is also hinged with a coordinating connecting rod; the other end of the coordinating connecting rod is hinged on a frame. The utility model adopts a connecting rod driving structure between the take-up axis and the power device to prevent the small bearing from rubbing the eccentric wheel directly, overcome the prior defects of easily worn and short life. The coordination on the take-up axis by connecting rod driving mechanism can effectively avoid dead point of movement, ensure smooth swinging of the take-up axis and the take-up rod which is interlocked with the take-up axis, improve the stability and quality of take-up action, reduce the abrasion and abnormal sound between driving parts and extend the service life.
Description
Technical field:
The utility model relates to quilting, embroidering machine tool technical field, refers in particular to the thread take-up mechanism of a kind of quilting machines, embroidering machine.
Background technology:
Quilting machines, embroidering machine are a kind ofly to make or the machinery of processing graphic pattern to lining, have thread take-up mechanism to be used for defeated line on quilting machines, embroidering machine and cooperate quilting or sew with long stitches the embroidery art and do.
Existing thread take-up mechanism, the rocking arm outer end that its thread taking-up axle stretches out is provided with protruding pin, packs in the eccentric grove on the eccentric wheel with protruding pin, and when the power drive eccentric wheel rotated, protruding pin then can relative motion in eccentric grove, obtains the take-up action with this.When implementing, little bearing generally can be equipped with in the end of protruding pin, with routing motion work.This structure with little bearing friction eccentric grove inwall, is hard contact directly, and is easy to wear, damage, and service life is short, and along with the intensification of the degree of wear, the track difference of take-up is just big more, causes the quality instability of making or embroidering, even waste product occurs.
Summary of the invention:
It is a kind of simple in structure that the purpose of this utility model is to provide, and the transmission smoothness is not easy to wear, the quilting machines of working stability, the thread take-up mechanism of embroidering machine.
For achieving the above object, the utility model adopts following technical scheme to realize:
The thread take-up mechanism of quilting machines, embroidering machine, comprise thread taking-up axle and power set, be fixed with an eccentric wheel on the final drive shaft of power set, stretch out an eccentric countershaft on this eccentric wheel, one end of the hinged composite rod in end of eccentric countershaft, this composite rod other end hinged one secondary bar, the rocking arm that the then hinged thread taking-up axle of this pair bar other end stretches out; Also hinged one coordinates connecting rod on the described composite rod, and this is coordinated on the then hinged frame of the other end of connecting rod; Composite rod is identical with the pin joint of secondary bar and coordination connecting rod.
The thread take-up mechanism that the utility model provides, be that the connecting rod drive mechanism is set between thread taking-up axle and power set, remove the mode of operation of little bearing direct friction eccentric wheel thus, overcome the short defective of easy to wear, life-span of prior art, coordinate out the take-up action of thread taking-up axle by jointed gear unit, can effectively avoid occurring the motion dead point, guarantee that the thread take-up tension lever swing of thread taking-up axle and interlock thereof is smooth and easy, improve the stability and the quality of take-up action; Can reduce simultaneously wearing and tearing and abnormal sound between the driving member, prolong and use.
Description of drawings:
Accompanying drawing 1 is the utility model perspective view;
Accompanying drawing 2 is another visual angle schematic diagram of Fig. 1.
The drawing reference numeral explanation:
10 thread taking-up axles, 11 rocking arms, 20 power set, 21 final drive shafts
22 eccentric wheels, 23 eccentric countershaft 30 composite rods 40 secondary bars
50 coordinate connecting rod
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Consult shown in Fig. 1,2, the thread take-up mechanism of quilting machines described in the utility model, embroidering machine, comprise thread taking-up axle 10 and power set 20, be fixed with an eccentric wheel 22 on the final drive shaft 21 of power set, stretch out an eccentric countershaft 23 on this eccentric wheel 22, one end of the hinged composite rod 30 in end of eccentric countershaft 23, this composite rod 30 other ends hinged one secondary bar 40, the rocking arm 11 that the then hinged thread taking-up axle of these pair bar 40 other ends stretches out; Also hinged one coordinates connecting rod 50 on the described composite rod 30, and this is coordinated on the then hinged frame of the other end of connecting rod 50.Composite rod 30 is identical with the pin joint of coordinating connecting rod 50 with the pin joint and the composite rod 30 of secondary bar 40, and promptly secondary bar 40 and coordination connecting rod 50 are with point articulated both sides in composite rod 30.
Shown in the figure, the power that power set 20 obtain is through final drive shaft 21 outputs, eccentric wheel 22 rotates and then drives eccentric countershaft 23 motions, during off-centre countershaft 23 eccentric rotary, 30 motions of pulling composite rod, be subjected to eccentric countershaft 23 during composite rod 30 motions and coordinate connecting rod 50 coordinations, obtain the movement locus of composite rod 30 the other end with this, the motion of composite rod 30 these ends passes to thread taking-up axle 10 through secondary bar 40 and rocking arm 11 just, make thread taking-up axle 10 obtain the take-up motion, promptly realize the ceaselessly defeated line of thread take-up tension lever of thread taking-up axle 10 interlocks.
Principle of Mechanical Designing is satisfied in the utility model design, and jointed gear unit harmony is good, and motion is smooth, so that the take-up motion stabilization of output, also reduces wearing and tearing and abnormal sound between the driving member, increases the service life.
