Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model scheme is described in detail.
As Fig. 1, the feed mechanism of the sewing machine that the present embodiment provides, is located in frame, primarily of frame 1, dossal plate 5, driving belt 31, position-limited rail 452, ramp 45, some push rod rod members 2, thimble 22 and two Live rollers 3.Live roller 3 is rotatably connected in frame 1, and two Live rollers 3 are in transmission connection by driving belt 31, forms closed loop driving-chain.Push rod rod member 2 to be arranged on driving belt 31 and respectively equably with driving belt 31 with the motion of the movement locus of setting.Movement locus is that a class is oval as shown in Figure 1, is made up of twice craspedodrome transfer path and two semi-circumference transfer paths.The high-end of position-limited rail connects two ramps respectively.Ramp 45 is respectively up gradient 451 and gug 453.Position-limited rail 452 is arranged on the side below driving belt 31 and arranges with a local path of above-mentioned movement locus, and limiting this local path in the present embodiment is the straight path being parallel to position-limited rail.Thimble 22 by push rod rod member about 2 slidably and be flexibly arranged on driving belt 31.
Live roller 3 in the present embodiment is driven by motor (not shown in FIG.) and rotates.Conveyer belt 31 is chain, and Live roller is sprocket wheel.Another kind of embodiment is: conveyer belt 31 is belt, and Live roller is belt pulley.
Further, the side in ramp 45 connects a stopper slot 4.Stopper slot 4 is connected to form by overhead gage 41 and lower baffle plate 42, forms channel-shaped.More preferably be designed to the both sides that employing two stopper slots 4, two stopper slots 4 are arranged on ramp 45 respectively accordingly, see Fig. 2,3.
As Fig. 6,7, push rod rod member is primarily of pulley 24, cylindrical shell 21, slide block 23, bottom bar 26 and return spring 25.Cylindrical shell 21 is fixed on driving belt 31.Thimble 22 and bottom bar 26 are connected in cylindrical shell slidably by the two ends of cylindrical shell 21 respectively.A cavity is formed between cylindrical shell 21 and bottom bar 26.Return spring 25 is located in cavity and the two ends of return spring 25 and is offseted with cylindrical shell 21 and bottom bar 26 respectively.Pulley 24 is articulated with the bottom of bottom bar 26, plays position-limiting action at push rod rod member through position-limited rail pushing and pressing on position-limited rail.Slide block 23 is connected to the both sides of cylindrical shell 21.More preferred design is, at slide block 23 hinged roller 231 respectively, makes the operation of push rod rod member more steadily, reliably with the frictional force reducing slide block and stopper slot 4.
Ramp is respectively up gradient and gug, and position-limited rail is a horizontal linear track.Ramp is connected to form by the inclined-plane that three sections of gradients are different.The gradient on the inclined-plane of gug is increased by the direction of up gradient to gug.See Fig. 4, Fig. 5.
Dossal plate 5 forms, see Fig. 8 by with the plate body of spliced eye 51 and dossal pin 52.Dossal pin 52 is connected to the side of dossal plate for cross-under cloth.Dossal plate realizes the movement on position-limited rail by spliced eye 51 and the connection of thimble 22.
As Fig. 9, this feed mechanism 6 is arranged in the frame 1 of sewing machine head 7 side, and dossal plate 5 operationally, is first passed through spliced eye 51 and the grafting of thimble 22, is arranged on the part push rod rod member 2 of linearly track distribution, see Fig. 1 by feed mechanism.After push rod rod member 2 arrives at up gradient, pulley 24 rolls on up gradient 451, and bottom bar 26 rises, and the return spring 25 in cylindrical shell is squeezed and starts to shrink, and thimble 22 upwards translation, inserts in spliced eye 51.The roller 231 of cylindrical shell 21 both sides slips into stopper slot 4.Push rod rod member is synchronized with the movement by belt-driven and dossal plate subsequently.When push rod rod member 2 arrives at gug, bottom bar 26 glides gradually with gug, and cavity becomes large, and return spring discharges, until push rod rod member and gug 453 depart from, driving belt drive cylindrical shell pulls thimble 22 makes thimble 22 and spliced eye 51 depart from.
The present embodiment provide the feed mechanism of sewing machine can Direct driver cross-under have the dossal plate of cloth to move along a straight line to carry out feeding operation, compared to burying folder machine, to avoid manual feeding and cloth to be hung on position on dossal pin relatively fixing, the mouth of a river is controlled, and operation can be sewed up with rearmost end foremost effectively to cloth, avoid reprocessing program.On the other hand, compared to sewing machine under main pin and auxiliary pin keep original speed of threading a needle, by the cloth regulating the feeding speed of cloth can tackle differing needles distance, wide usage is stronger, as long as and equidistantly cloth is plugged on dossal pin when fixing cloth, working strength reduces greatly, effectively reduces human cost.
