Description
Technical field
The utility model belongs to technical field of sewing equipment, relates to the pay-off of a kind of pay-off, particularly a kind of Sewing machines.
Background technology
On Sewing machines in the past, turn round by certain characteristics of motion and movement relation by each parts of drive motor Sewing machines that are installed on the Sewing machines, finally make the feeding dentification be similar to the periodic motion of elliptical orbit.
In order to realize that Sewing machines makes function, be provided with the needle plate that has through hole, the fixing presser feet of sewing in the base plate position on the top of feeding tooth movement locus.The feeding tooth is when carrying out the sub-elliptical orbiting motion, and the top of feeding tooth track is protruded from the through hole of needle plate and continued to press the sub-elliptical orbiting motion, and thus, the feeding tooth has been realized the conveying function to sewing.
Sewing machines as shown in Figure 5 is provided with feed spool 2, feed lifting rock shaft 3 in base plate 1 inside, and toggle 4 is lifted tooth eccentric mechanism 5, feeding bearing 6, feeding dental branches frame 7, feeding tooth 8, needle plate 9, presser feet 10.
The CD-ROM drive motor of feed lifting rock shaft 3 by casing inside makes it to form and rotatablely moves, toggle 4 is with the swing in the cycles such as being converted to that rotatablely moves of feed lifting rock shaft 3 and pass to feed spool 2, feed spool 2 passes to feeding dental branches frame by feeding bearing 6 with the preiodic type swing, lifts tooth eccentric mechanism 5 rotatablely moving of feed lifting rock shaft 3 is converted to equifrequent reciprocating motion and passes to feeding dental branches frame 7.
The two ends of above-mentioned feeding dental branches frame accept to come from the equifrequent periodic wobble and the reciprocating motion of feed spool 2 and feed lifting rock shaft 3 respectively, have realized seesawing and moving up and down of feeding dental branches frame 7 thus.Finally make feeding dental branches frame form the motion state that is similar to elliptical orbit, therefore the feeding tooth 8 that is installed in feeding dental branches frame top also forms the motion state (as shown in Figure 6) that is similar to elliptical orbit.
But on above-mentioned Sewing machines, feed lifting rock shaft 3 is positioned on the feeding tooth feed direction, away from operator's position, feed spool 2 is positioned on the feeding tooth feed direction, presses close to operator's position, presser feet 10 is positioned on the feeding tooth feed direction, near feed lifting rock shaft 3 but away from the position of feed spool 2.Therefore, L1 as shown in Figure 6 and L2, the close feed lifting rock shaft of the center of gravity of presser bar 10a is but away from feed spool.As shown in Figure 7, when the feeding tooth was carried sewing, the upper and lower displacement amount of feeding tooth was bigger than an end H2 of close feed spool 2 at the end H1 near feed lifting rock shaft 3.
On the other hand, when feeding tooth 8 was carried sewings, the state of moving up and down of feed lifting rock shaft 3 made the presser feet 8 near feed lifting rock shaft 3 produce bigger upwards beating, and was carrying out high speed when carrying sewing, sewing can not be caused the sewing thread trace length of Sewing machines inhomogeneous by correct conveying.For weakening this phenomenon, can utilize cam pin 11 and cam pin 12 Height Adjustment that protrude at feeding tooth two ends can be become consistent (as shown in Figure 8) from needle plate 9, thereby but such adjustment might make feeding tooth 8 protrude the needle plate top near the pole axis focus of the sub-elliptical track of an end of feed spool 2 produce the phenomenon of oppositely carrying sewing.
