According to the embroidery machine nose disclosed by the utility model, the independent driving device for driving the pressure foot driver is arranged, the driving device comprises the driving shaft, the torsion beam arranged on the driving shaft, and the connecting arm, one end of the connecting arm is rotatably arranged on the pressure foot driver, and the other end of the connecting arm is rotatably connected with the torsion beam; and compared with a plane connecting rod mechanism, the embroidery machine nose is convenient for design and accurate manufacturing and has the beneficial effects of capability of running at a high rotation speed, few running faults, long service life, high driving sensitivity, and capability of improving the pressure foot driving effect.
Description
Technical field
The utility model relates to a kind of embroidery machine head.
Background technology
In the work of embroidery machine head, need shank constantly to do down pin, pumping of resetting, its down pin rely on driver, resetting relies on the back-moving spring on the shank to reset.Along with the rotating speed of embroidery machine is more and more faster, when meeting or exceeding 800 rev/mins, the hysteresis that resets of shank and presser feet needs the presser feet driver to come the assist location presser feet for this reason usually, and the spacing presser feet of presser feet piece on the presser feet driver prevents presser feet bump needle plate.
The presser feet driver is done the intermittent reciprocating motion by the cam mechanism that is arranged in the head; during the head running; pin under the driver drives shank; presser feet and presser feet driver are along with pin under the shank is descending; presser feet and shank are done to reset after of short duration intermittence; in the transients of and drive pressure pin preset spacing at the intermittent presser foot piece; the stressed maximum of cam; it also is the weakest link of cam edge thickness; because the technology of domestic manufacturing cam and the restriction of cam material; when further raising or the work for a long time of embroidery machine speed, the cam easy deformation makes and the track inaccuracy has influence on resetting of shank; perhaps cam directly damages; break down, shutdown maintenance, the cam drive structure has seriously reduced the efficient of embroidery machine.
ZL201020275528.7 discloses a kind of planar linkage mechanism and has driven depressor, same because the cause of design and manufacturing, the planar linkage mechanism of machinery error occurs easily and produces serious wearing and tearing, especially high-speed cruising, thereby cause the too early damage of planar linkage mechanism, be far smaller than projected life its service life.
Two kinds of above-mentioned problems that embroidering machine head produced, the further raising of restriction embroidery machine speed is had relatively high expectations to working environment simultaneously.
Summary of the invention
The utility model provides a kind of pressure foot lifting piece highly sensitive, the embroidery machine head of dependable performance for solving the problem that prior art in use exists.
The technical scheme that the utility model solves existing issue is: a kind of embroidery machine head, comprise head shell, be arranged at the presser feet driver of the driver, driving and the location presser feet that drive shank in the head shell, as improvement, described presser feet driver is provided with a drive unit independently, this drive unit comprises reciprocal drive shaft rotating, be arranged at and turn round arm, the rotatable linking arm that is arranged on the presser feet driver of an end on the driving shaft, and rotatable being arranged at of the described linking arm other end turned round on the arm.
As further improvement, described driving shaft one or both ends are provided with a holder, and described holder is arranged in the head shell.
As further improvement, described driving shaft is provided with stepper motor.Above-mentioned stepper motor is arranged on the head shell and is connected with driving shaft by the belt belt wheel.
As further improvement, described driving shaft one end is provided with belt wheel or gear.
As further improvement, described presser feet is provided with the projection that cooperates with the set presser feet piece of presser feet driver, and described presser feet piece cooperates with projection on the presser feet and promotes spacing presser feet.
As further improvement, comprise that also a coding disk and optocoupler assembly constitute the presser feet mechanism for monitoring, described coding disk is arranged on the driving shaft, and the drive motors of described mechanism for monitoring and driving shaft constitutes closed loop or semiclosed loop.
The utility model compared with prior art, one independent drive unit is set drives the presser feet driver, the driving shaft of this drive unit, be arranged at and turn round that arm, an end rotatablely are arranged on the presser feet driver, the other end is rotatably connected and turns round arm on the driving shaft, this structure is convenient to design than planar linkage mechanism and is accurately made, its beneficial effect is that this product structure can move by high rotating speed, operation troubles is few, the life-span is long, driving is highly sensitive, improves the driving effect of presser feet.

The specific embodiment
Referring to Fig. 1-3, the implementation case comprises head shell 1, be arranged at the presser feet driver 4 of driver, driving and the location presser feet 3 of the driving shank 11 in the head shell 1, presser feet driver 4 is provided with a drive unit independently, this drive unit comprises reciprocal drive shaft rotating 2, be arranged at and turn round arm 21, the rotatable linking arm 31 that is arranged on the presser feet driver 3 of an end on the driving shaft 2, and rotatable being arranged at of linking arm 31 other ends turned round on the arm 21.
In order to improve stability, driving shaft 2 one or both ends are provided with a holder 22, and holder 22 is arranged in the head shell 1, and driving shaft 2 is arranged in the holder 22 by bearing.
As optimization, the presser feet driver is 4 spacing to improve, the accuracy of location presser feet 3, comprise that also a coding disk and optocoupler assembly constitute the presser feet mechanism for monitoring, coding disk is arranged at an appropriate location on the driving shaft 2, the drive motors of mechanism for monitoring and driving shaft 2 constitutes closed loop or semiclosed loop, the lower position of presser feet piece 41 restriction location presser feets 3 can be used as the set point of coding disk, and the system of closed loop or semiclosed loop can effectively prevent to press driver 4 offside operations, thereby guarantees that presser feet 3 accurately moves.
