Description

Universial eye buttonhole machine

The utility model is general knob button hole maker, and it is the new accessory workpiece that designs for articles of dress, can be balancing point multifunctional series Sewing machines knob keyhole function is provided, and belongs to the attachment to a sewing machine class.

As everyone knows, knob button eye is the indispensable technologies of high-grade clothes such as clothes, particularly western-style clothes.And present large-scale knob lockstitch button holder, need surplus the RMB 60,000 yuan as Japan's 299 types of import or 101 types, homemade south China board is also wanted surplus the RMB 10,000 yuan, the family expenses button hole maker that has only that minority specialty factory just can acquire, sells on the existing market is that the imitative U.S. wins family's old product of the forties, transmission mechanism is the swing of interior grooved cam department, eccentric department stroke.Work characteristics is that shank is not swung, and is vacillated now to the left, now to the right by button hole maker and does the tortuous Z-shaped continuous action of advancing.It is stiff that the product effect can only lock out needle tracking, the button eye that shape is irregular, as shown in Figure 4.

The purpose of this utility model is to provide a kind of energy high-quality to finish the popular knob button hole maker of knob button eye technology to articles of dress, transmission mechanism is by worm screw, worm gear, gear, tooth bar, can be by the accurate calibration of worm gear, distribute each gear, finish stroke, track, functions such as rotation, and its work characteristics is the shank swing, packs tightly heart yearn and does

Shape is advanced, and is selected arbitrarily in 10～30mm scope.The product effect can lock out the bag stalk and have third dimension, the knob button eye that needle tracking is standardized, as shown in Figure 5.

In order to achieve the above object, the utility model adopts following design to realize.With the needle rod range of sewing machine is power, and the shank dog snaps in shift fork 1, back and forth dials commentaries on classics ratchet 3 ， And and drives ratchet wheel shaft 2 and coaxial worm 21.Press gearratio by worm screw 21 and rotate worm gear 7.Press the accurate calibration of gearratio by worm gear 7, coaxial rotating distance gear 9 and swiveling gear 11, the accurately work and the intermittent time of dispense stroke and two gears of revolution.Drive travelling gear 10 And by power transmission shaft 8 coaxial running driving wheels 14 by stroke gear 9, revolution makes down planker 13 by the track reciprocating motion in stroke internal gear 15.When planker 13 is reciprocating instantly,, make down the revolution of planker 13 interlocks give as security pin combination 26 along the reciprocating motion of intersecting lens track by track garden post 24 spacing slip in track locating slot 25.Because knob button eye is made up of intersecting lens and one and half gardens, therefore, when stroke must turn round 180 ° of 50% strokes of advancing again to 50% the time

Shape button eye, thus at stroke by 50% o'clock, stroke gear 9 intermittently, and swiveling gear 11 rotates revolution interlock tooth bars 17, interlock revolution pinion 16 makes revolution give as security pin combination 26 and drives clothes again, finishes 180 ° of revolutions.After this, swiveling gear 11 is intermittently rotated by stroke gear 9, and 50% stroke of having gone further is Shape button eye.Stroke gear 9 and swiveling gear 11 are coaxial complementary intermittently wheels, are far more than that the design is swung by shank, and track does not repeat for crossing and revolution

The characteristics of shape so ad hoc have the bag stalk to give as security pin 19, only need the eedle centrally aligned to give as security pin 19 centers during use, put on heart yearn, and the swing shank can lock out the three-dimensional stitching of bag stalk, and as shown in Figure 5, intersecting lens track stroke 50% place does 180 °

The shape rotation, 50% stroke of advancing again is the peculiar technology overall design of the utility model.

The utility model is described in further detail below in conjunction with accompanying drawing:
