Play acupuncture cloth machine head of embroidery machine
Technical field
The present invention relates to field of textile machinery, particularly relate to a kind of machine head of embroidery machine parts.
Background technology
The processing of present large-scale industry textiles is all on cloth, embroider out pattern by computerized emboridering machine; Computerized emboridering machine is first made a plate with embroidery CAD software when embroidering, after generating example edition, the disc being loaded with embroidering program and style is successively put into computer disk driver respectively, under program, style coordinate value changes into and the frame X that stretches tight, the signal of telecommunication that Y-direction displacement is suitable by computer, deliver to after X, Y, Z SCM system carries out the process of motor lifting speed, to stretching tight, frame and Z stepper motor control; In processing embroidered fabric, the area of fabric is all larger is again soft material, therefore embroidering when pin contacts with fabric and fabric can be made to deform, just must consider the factor that fabric is out of shape like this, otherwise the pattern embroidered out will inevitably lose shape when making a plate; Fabric distortion is usually relevant with speed when embroidering eedle-punched non-wovens, and under normal circumstances, the thorn cloth degree of depth is less, and speed is faster, then fabric distortion is less, makes a plate easier; Existing embroidery pin is all decline with head one when doing thorn cloth motion, and this form makes the thorn cloth finite rate embroidering pin, cannot reduce fabric distortion.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of embroidery pin played on acupuncture cloth machine head of embroidery machine and does not follow head action in the thorn cloth stage, but utilize elastic-restoring force to move downward thorn cloth rapidly, relative to the pattern of mass motion thorn cloth in prior art, reduce the distortion that fabric Yin Cibu produces, reduce the difficulty of plate-making, the accuracy of needlework location and embroidery aesthetics are improved.
The present invention is achieved in that a kind of bullet acupuncture cloth machine head of embroidery machine, comprise head body, static iron core and moving armature is provided with in described head body, described static iron core is outer is wound with coil by bobbin, ejector spring is provided with between described moving armature and static iron core, fixedly guide post is housed bottom moving armature, is set with fairlead outside described guide post, the bottom of described guide post is provided with embroidery pin.
Described static iron core is U-iron core, and described moving armature is the U-shaped armature corresponding with static iron core.
Described bobbin has two, and the bobbin described in a pair is symmetricly set on the dual-side of U-shaped static iron core.
Described fairlead is fixedly mounted in head body, and described guide post and fairlead form moving sets.
Described fairlead offers the gathering sill of an axis, described guide post is provided with a positioning sliding block, described positioning sliding block matches with gathering sill.
The embroidery pin that the present invention plays on acupuncture cloth machine head of embroidery machine does not follow head action in the thorn cloth stage, but utilize elastic-restoring force to move downward thorn cloth rapidly, relative to the pattern of mass motion thorn cloth in prior art, reduce the distortion that fabric Yin Cibu produces, reduce the difficulty of plate-making, the accuracy of needlework location and embroidery aesthetics are improved.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention plays acupuncture cloth machine head of embroidery machine.
In figure: pin embroidered by 1 head body, 2 static iron cores, 3 moving armatures, 4 bobbins, 5 coils, 6 ejector springs, 7 guide posts, 8 fairleads, 9.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's statement.
Embodiment 1
As shown in Figure 1, a kind of bullet acupuncture cloth machine head of embroidery machine, comprise head body 1, static iron core 2 and moving armature 3 is provided with in described head body 1, described static iron core 2 is outer is wound with coil 5 by bobbin 4, is provided with ejector spring 6, bottom moving armature 3, guide post 7 is fixedly housed between described moving armature 3 and static iron core 2, be set with fairlead 8 outside described guide post 7, the bottom of described guide post 7 is provided with embroiders pin 9, embroider pin 9 when embroidery machine power-off is shut down to naturally droop, when start is embroidered, the elastic force that embroidery pin 9 overcomes ejector spring 6 is adsorbed on a high position by electromagnetic force, embroidery pin 9 in this device moves when carrying out thorn cloth and is divided into two stages, first embroidery pin 9 and head body 1 entirety move downward, when embroidering pin 9 near web surface, coil 5 power-off, static iron core 2 loss of excitation is separated with moving armature 3, moving armature 3 drives embroidery pin 9 to move downward thorn cloth rapidly under the elastic thrust of ejector spring 6, greatly improve the speed of thorn cloth, the degree of depth of thorn cloth can realize by regulating the range of moving armature 3, very convenient.
In the present embodiment, in order to ensure that moving armature 3 moves downward the stationarity of process, to improve the accuracy of embroidering pin 9 thorn cloth, described static iron core 2 is U-iron core, and described moving armature 3 is the U-shaped armature corresponding with static iron core 2; Described bobbin 4 has two, and the bobbin 4 described in a pair is symmetricly set on the dual-side of U-shaped static iron core 2, and during action, both sides are simultaneously stressed, can guarantee to embroider pin 9 downward thorn cloth stably in conjunction with fairlead 8.
In the present invention, described fairlead 8 is fixedly mounted in head body 1, and described guide post 7 forms moving sets with fairlead 8; In addition in order to avoid the rotation of moving armature 3 is trembleed, described fairlead 8 offers the gathering sill of an axis, described guide post 7 is provided with a positioning sliding block, and described positioning sliding block matches with gathering sill.
