The utility model also provides an embroidery machine, including the aircraft nose, install foretell presser foot hoist mechanism on the aircraft nose. The utility model discloses a presser foot promotes the motor drive cam, concentrates to promote all presser foots, and the mechanism is simple, simple to operate, does not have complicated circuit worried, and this mechanism only needs as needed lifting presser foot moreover, and the little frequency of operation of load is not high, and there is the condition of damage hardly in the driving medium, we can say and exempts from the maintenance completely.
Description
Technical field
This utility model relates to embroidery machine, particularly relates to embroidery machine presser foot hoisting mechanism.
Background technology
The pressure foot lifting structure of tradition embroidery machine includes lifting cylinder, and the piston mandril connection of lifting cylinder carries
Rising block, lift block is used for promoting presser feet.Each head is the most separately installed has lifting cylinder to promote presser feet, defect
Being relatively costly, and pneumatic line is complex, easily leak air, it is the most convenient to keep in repair.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of presser bar lifting mechanisms, simplifies structure,
Convenient maintenance.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that a kind of presser bar lifting mechanisms,
Including the presser slide block driving presser feet to rise, it is additionally provided with the cam being installed on pressure foot lifting axle and is installed on pin
Connecting rod on axle, described pressure foot lifting axle is driven by pressure foot lifting motor, and described connecting rod connects torsion spring,
Under torsion spring effect, the first end of described connecting rod and cam surface Elastic Contact, the second end supports with presser slide block elasticity
Connect.
Preferably, described connecting rod is downward opening V-type shape.
Preferably, the output shaft of described pressure foot lifting motor or coupled with pressure foot lifting axle by shaft coupling,
Or by gear-driven assembly, or by belt wheel transmission Component driver pressure foot lifting axle.
Preferably, the first end and the connection of the second end of described connecting rod has rolling bearing.
Preferably, described connecting rod is installed in mounting seat, and described mounting seat and pressure foot lifting axle are installed on head
On housing.
This utility model additionally provides a kind of embroidery machine, including head, is provided with above-mentioned presser feet on head
Hoisting mechanism.
Further, several heads are arranged side by side, and pressure foot lifting axle is connected through each head.
This utility model uses pressure foot lifting motor to drive cam, concentrates and promotes all presser feets, mechanism is simple,
Easy for installation, do not have complicated circuit worried, and this mechanism only needs lifting presser feet when necessary, loads little
Operating frequency is the highest, and driving member there's almost no the situation of damage, it may be said that freedom from repairs completely.Its advantage exists
In more economical mechanism stability more preferably, and the simplest at automatically controlled aspect.
Accompanying drawing explanation
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of head；
Fig. 2 is presser bar lifting mechanisms structural representation.
Detailed description of the invention
As depicted in figs. 1 and 2, head 2 comprises such as lower component: head shell 20 and be installed on head shell 20
On the presser feet axis of guide 21, slider guide axle 24, presser feet 23 slide be located on the presser feet axis of guide 21, presser feet is led
Being provided with presser feet spring 22 to axle 21, presser slide block 25 is located on slider guide axle 24, and presser slide block 25 is along cunning
The block axis of guide 24 moves upward, and drives presser feet 23 to rise along the presser feet axis of guide 21, downward in presser slide block 25
And after separating with presser feet 23, presser feet 23 resets downwards under the effect of presser feet spring 22.It is shuttle race below head 2
3, shuttle race is provided with needle plate 31.The effect of presser bar lifting mechanisms 1 is when non-embroidery state, promotes presser feet 23
To higher height during embroidery relatively, make presser feet 23 away from needle plate 31, now facilitate the replacing of cloth or be
Carry out maintenance operation.
Wherein, presser bar lifting mechanisms 1 includes the cam 13 being installed on pressure foot lifting axle 12 and is installed on pin
Connecting rod 15 on axle 16, connecting rod 15 is installed in mounting seat 26, and mounting seat 26 and pressure foot lifting axle 12 are pacified
It is loaded on head shell 20.Pressure foot lifting axle 12 is driven by pressure foot lifting motor 10, and connecting rod 15 connects to be had
Torsion spring 17, torsion spring 17 be fixed on connecting rod 15 with in mounting seat 26, under torsion spring 17 acts on, the of connecting rod
One end and cam surface Elastic Contact, the second end and presser slide block bottom surface Elastic Contact.
It addition, connecting rod 15 is downward opening V-type shape, the first end and second end of connecting rod are respectively connected with rolling
Dynamic bearing 14, to reduce gearing friction, improves reliable transmission.
The output shaft of pressure foot lifting motor 10 is coupled with pressure foot lifting axle 12 by shaft coupling 11 and is driven presser feet
Lift shaft 12, or gear-driven assembly, belt wheel transmission Component driver pressure foot lifting axle 12 can also be passed through.
This presser bar lifting mechanisms operation principle is that pressure foot lifting motor 10 drives pressure foot lifting axle 12 to rotate, pressure
Foot lift shaft 12 drives the cam 13 being installed on this axle to rotate, and cam 13 drivening rod 15 is with bearing pin 16
It is pivoted, owing to torsion spring 17 makes the cam surface of connecting rod 15 one end and cam 13 be close to, the other end and pressure
Foot slide block 25 bottom surface is tangent, and therefore presser slide block 25 can only be along the presser feet axis of guide 21 by connecting rod 15 drive
Lower motion, drives presser feet 23 to move up and down when presser slide block 25 moves up and down.
