Description
Technical field
The utility model is related to a kind of embroidering machine head, and in particular to a kind of high speed embroidery machine head.
Background technology
Chenille embroidery machine head used at present, the drive mechanism driving tube coordinated using cam and swing rod with closing chute
Mouth bar, towel shank and presser bar pump, and one end of swing rod, which is provided with, can coordinate the roller in cam channel, when
During cam rotation, the roller of swing link end part is mobile in cam channel to swing the swing rod other end, so that ozzle bar, towel pin
Bar and presser bar pump.Because roller coordinates in cam channel, therefore the diameter of roller is necessarily less than chute
Width.Obviously, when cam rotation, roller will easily be caused in cam channel with the speed rotation rolling of decades of times
Roller heating abrasion, or even scrap, the technical bottleneck for causing existing towel embroidery machine speed to be difficult to break through 650 revs/min, so that
It significantly limit the operating efficiency of towel embroidery machine.
The content of the invention
It is more stable when can greatly improve that operating efficiency, service life are longer it is an object of the invention to provide one kind, use
High speed hook line embroidering machine head.
To achieve the above object, the utility model is adopted the following technical scheme that：A kind of high speed hook line embroidering machine head, including machine
Provided with the towel shank of ozzle, lower end provided with towel pin, lower end presser bar and driving machine provided with presser feet in shell, the casing
Structure, drive mechanism can make ozzle, presser feet and towel pin pump, and the ozzle is located at the lower end of ozzle bar, described
Ozzle bar, towel shank and presser bar is spaced sets, the drive mechanism includes the first cam, the first swing rod, second convex
It is set in the middle part of wheel, the 3rd cam, the second swing rod and the 3rd swing rod, first swing rod on swing rod axle, first swing rod
One end and the towel shank link, and the other end of first swing rod is fixed with the first roller, first roller with it is described
First cam outer rim lower surface offsets, and first roller and first cam linkage, is arranged in the middle part of second swing rod
On swing rod axle, one end of second swing rod is linked with the ozzle bar, and the other end of second swing rod is fixed with second
Roller, second roller offsets with the second cam outer rim lower surface, and second roller joins with second cam
It is dynamic, it is set in the middle part of the 3rd swing rod on swing rod axle, one end and the presser bar of the 3rd swing rod link, the described 3rd
The other end of swing rod is fixed with the 3rd roller, and the 3rd roller offsets with the 3rd cam outer rim lower surface, and described
Three rollers are with the 3rd cam linkage, first cam rotation so that the first roller is moved up and down, and second cam turns
Move so that the second roller is moved up and down, the 3rd cam rotation is so that the 3rd roller is moved up and down.
During using the utility model, the first cam, the second cam and the 3rd cam rotation in the presence of motor, due to
One roller and the first cam linkage, the first swing rod can be swung up and down with the rotation of the first cam, so that above and below towel shank does
Move back and forth；Similarly so that ozzle bar and presser bar pump.The utility model is by swing rod（First swing rod,
Second swing rod, the 3rd swing rod）On roller and cam（First cam, the second cam, the 3rd cam）Outer rim coordinate, so as to
The size of appropriate increase roller, when cam rotation, the number of turns of roller rotation can ensure basically identical with the cam rotation number of turns, from
And the friction of roller is greatly reduced, and then the rotating speed of cam can be improved and improve the operating efficiency of chenille embroidery machine head and use the longevity
Life, makes the operating rate of the head of the utility model towel embroidery machine reach more than 1000 revs/min；In addition, the utility model
Using swing rod, towel is for answering the first swing rod, and ozzle the second swing rod of correspondence, presser feet the 3rd swing rod of correspondence occupies little space, and can
Make precision of the present utility model higher, the towel embroidery quality woven is more preferable.If ozzle bar is set in outside towel shank,
Need to consider the concentric problem of ozzle bar and towel shank when being processed, towel shank of the present utility model, ozzle bar and
Presser bar is spaced, and ozzle bar is not set on towel shank, makes structure of the present utility model simpler, is easy to
Process and assemble and maintenance, precision are also higher.The utility model uses swing rod（First swing rod, the second swing rod, the 3rd swing rod）, power transmission
When abrasion it is few, it is easy to keep precision, and roller is easy to wear in cam structure, and the chute of cam（Profile）Bad processing, easily
The problem of gap between generation roller and chute is excessive or too small, gap crosses conference and produces larger noise, and gap is too small then
Roller is difficult to put into chute；And the utility model is avoided that the play of adjacent links is asked compared with for the drive mechanism for using connecting rod
Topic, stability is higher.Wherein, can the first roller, the second roller and the 3rd roller can be used bearing, between cam outer rim and roller
The power of rolling friction is smaller, the utility model is born higher rotating speed without being damaged.
Preferably, first cam, the second cam and the 3rd cam are each attached on camshaft, first swing rod
On be fixed with some first torsionsprings, the casing and be fixed with fix bar, one end of first torsionspring with it is described
First swing rod offsets, and the other end and the fix bar of first torsionspring offset, and the fix bar is located at the swing rod
Above axle, it is fixed with second swing rod on some second torsionsprings, the 3rd swing rod and is fixed with some 3rd torsionsprings,
One end of second torsionspring offsets with second swing rod, the other end and the fix bar of second torsionspring
Offset, one end and the 3rd swing rod of the 3rd torsionspring offset, the other end of the 3rd torsionspring with it is described
Fix bar offsets.
The utility model when in use, cam axle so that first cam driven the first roller lower edge, the first swing rod
Moved up away from one end of the first roller to drive towel shank to move up, subsequent cam axle is so that the first cam is moved up, the
In the presence of one torsionspring, the first swing rod is moved down close to one end of towel shank, so that on the first roller energy of the first swing rod
Move with the first cam contact so that the first roller and the first cam can be in contact all the time, to realize that the first swing rod can be done back and forth
Wobbling action；Similarly, acted with the reciprocally swinging for realizing the second swing rod and the 3rd swing rod.Wherein, due to first convex on camshaft
The outer rim of wheel, the second cam and the 3rd cam is different, and same cam is different in the power that different time applies to same roller,
To ensure the balance of power, it is necessary to select the torsionspring of varying strength, or select the torsionspring of varying number.
Preferably, being fixed with the towel shank on fixed block and first time fixed block on first, the ozzle bar
It is fixed with second on fixed block and second time fixed block, the presser bar and is fixed with fixed block and the three times fixations on the 3rd
