Description
Technical field
The utility model belongs to sewing machine technical field, particularly the driving mechanism of sweater intelligence to knitting needle swing arm in order sewing machine.
Background technology
Sewing machine, also known as being disk sewing machine, uses the machine of suture sweater running-on.The garment piece sewing work of sweater can be completed by sewing machine efficiently, fast, greatly improve than the efficiency of manual suture.Knitting needle swinging arm device in existing sewing machine generally comprises arm shaft, is socketed in the centering block on arm shaft and spring, is fixed on the swing arm of arm shaft end, and is positioned at swing arm side and the paving inconsistent with centering block side helps transmission device.During knitting needle, centering block, by connecting rod connecting eccentric wheel, is rotated by eccentric wheel and drives centering block to swing, thus swing arm is swung around arm shaft; Paving helps transmission device one end and centering block side to conflict, and the other end is close on the edge contour of eccentric cam, and when eccentric cam rotates, paving helps transmission device to make centering block drive arm shaft to move axially by lever principle, thus drives swing arm to move forward and backward.This type of drive realizes mainly through eccentric wheel and eccentric cam, but device complicated integral structure, transmission underaction, the poor stability of knitting needle swing arm motion.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, the driving mechanism of the sweater that flexibility is good, stability is high intelligence to knitting needle swing arm in order sewing machine swing arm being swung and moves axially.
For this reason, the technical solution of the utility model is: the driving mechanism of sweater intelligence to knitting needle swing arm in order sewing machine, comprises arm shaft, be socketed in the centering block on arm shaft and spring, be fixed on the swing arm of arm shaft front end; Plane bearing is provided with between centering block and spring; It is characterized in that: also comprise a belt shaft, belt shaft is positioned at below arm shaft, vertically with arm shaft arranges; Described belt shaft is fixed one and knit line wheel and eccentric cam, the periphery knitting line wheel is provided with the grooved tracks of an oval ring; The one end side that described centering block is placed on arm shaft is provided with baffle plate, and the other end is provided with clutch shaft bearing, and clutch shaft bearing is placed in grooved tracks; Described centering block is provided with lever relative to the opposite side of spring, and lever is arranged in sewing machine frame by alignment pin; Described lever two ends are respectively equipped with the second bearing and the 3rd bearing, and the edge of eccentric cam is close to by the second bearing, and the 3rd bearing is against on the baffle plate of centering block side.
Further, described grooved tracks be looped around knit line wheel periphery on, integral inclined, in grooved tracks transverse two summits with knit the distance difference that line takes turns same end face and determine the length that clutch shaft bearing swings, the angle namely swung with swing arm adapts.
Further, described eccentric cam is provided with arcuate socket, is fixed as one by screw; Described eccentric cam by arcuate socket with knit line and take turns and fix, described eccentric cam and to knit the angular relationship that line takes turns adjustable within the scope of arcuate socket.
The utility model is arranged on sewing machine, and belt shaft is driven by the transmission mechanism on sewing machine, and Timing Belt movable pendulum arm moves in back and forth and right and left directions.Swing arm swings: knit line wheel and rotate under the drive of belt shaft, the clutch shaft bearing of centering block be placed in knit line wheel grooved tracks in, clutch shaft bearing is along with the rotation of knitting line wheel, swung with along belt shaft direction by integral inclined grooved tracks, namely left and right directions swings, then centering block drives arm shaft to swing, and the swing arm of resulting belt movable pendulum arm axle front end swings in the lateral direction.
Swing arm moves forward and backward: the spring of the compression at centering block rear is to centering block elastic force forward, and baffle plate by the right side of elastic force effect driven forward lever, thus makes the second bearing on the left of lever move backward to be close to the edge contour of eccentric cam; Eccentric cam rotates under the drive of belt shaft, and the edge contour of eccentric cam can impel the left and right sides of lever to swing.When eccentric cam is greater than the elastic force received on the right side of lever to the thrust on the left of lever, on the right side of lever, rearward promote centering block, thus make centering block drive swing arm to move backward; When eccentric cam is less than the elastic force received on the right side of lever to the thrust on the left of lever, spring forwards promotes centering block, thus makes centering block drive swing arm to move forward.
The utility model cancels original bar linkage structure and eccentric wheel, and drive swing arm to rotate by the grooved tracks of knitting on line wheel, overall structure is simple; Arcuate socket on eccentric cam can make eccentric cam adjustable within the specific limits with the angular relationship of knitting line wheel, and make swing arm mass motion stability high, knitting needle work is more flexible.
