The rotary embroidery machine of cloth stretching holder
Technical field
The present invention relates to field of textile machinery, more particularly to a kind of embroidery machine.
Background technology
The processing of present large-scale industry textile is all that pattern is embroidered out on cloth by computerized emboridering machine;Computer embroidery
Machine is first made a plate in embroidery with embroidery CAD software, and after generating example edition, the disc for being loaded with embroidering program and style is successively put respectively
Enter in computer disk driver, under program, computer by style coordinate value change into it is suitable with the frame X that stretches tight, Y-direction displacement it
Electric signal, after being sent to the progress motor lifting speed processing of X, Y, Z SCM system, taut frame and Z stepper motors are controlled;Processing
In embroidered fabric, the area of fabric is all bigger and is soft material, therefore can be so that fabric is sent out when embroidered needle is in contact with fabric
Change shape, so just has to consider the factor of fabric deformation in plate-making, and the pattern otherwise embroidered out will necessarily lose shape;
X, the stepper motor of Y-direction drive taut frame motion in embroidery, and Z motor driven embroidered needles only move up and down;Embroider
When fully relies on taut frame, and mobile just needs configure two motors for taut frame in the x, y direction, and set corresponding support and transmission
System, the support and motor in one of direction are directly installed on another support, and this support being stacked and motor exist
Error is larger caused by vibration during transmission, and for rectangular taut frame because discontinuity, these factors all improve system in addition
The difficulty of version, is unfavorable for the design of embroidery pattern.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of rotary embroidery machine of cloth stretching holder and turned because employing taut frame
It is dynamic, head along taut frame R to the pattern moved, with respect to the horizontal plane for, the motion of head and taut frame is all unidirectional, and is stretched tight
Frame can use the taut frame of the circle of even tension, face when improving the accuracy of head needlework location, and reducing embroidered needle thorn cloth
The deformation of material, reduces the difficulty of plate-making, and then improves the aesthetics of embroidery pattern.
What the present invention was realized in:A kind of rotary embroidery machine of cloth stretching holder, including embroidery frame body and embroidering machine head, institute
State embroidery frame body to be supported by claw, the claw is connected by transmission mechanism with electric rotating machine, and the electric rotating machine drives card
Pawl does axial-rotation, and the embroidering machine head is arranged in vertical lifting bracket by telescopic arm, and telescopic arm drives embroidering machine head to do
Linear motion, the straight-line trajectory of embroidering machine head pass through the center of rotation of embroidery frame body.
Described embroidery frame body is circular taut frame.
The electric rotating machine is stepper motor, and decelerator is provided with electric rotating machine.
The vertical lifting bracket includes lifting motor, vertical support, leading screw and feed screw nut, and the leading screw passes through bearing
It is vertically installed on vertical support, the feed screw nut forms lead screw pair with leading screw, and the telescopic arm is arranged on feed screw nut,
The lifting motor drives leading screw rotation.
The rotary embroidery machine of cloth stretching holder of the present invention rotates because employing taut frame, and head is along taut frame R to the pattern moved, phase
For horizontal plane, the motion of head and taut frame is all unidirectional, and taut frame can use the taut frame of the circle of even tension,
The deformation of fabric when improving the accuracy of head needlework location, and reducing embroidered needle thorn cloth, the difficulty of plate-making is reduced, and then
Improve the aesthetics of embroidery pattern.
Brief description of the drawings
Fig. 1 is the structural representation of the rotary embroidery machine of cloth stretching holder of the present invention.
In figure:1 embroidery frame body, 2 embroidering machine heads, 3 claws, 4 electric rotating machines, 5 telescopic arms, 6 vertical lifting brackets, 61 liters
Motor, 62 vertical supports, 63 leading screws, 64 feed screw nuts drop.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention stated has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiment 1
As shown in figure 1, a kind of rotary embroidery machine of cloth stretching holder, including embroidery frame body 1 and embroidering machine head 2, the embroidery
Frame body 1 is supported by claw 3, and the claw 3 is connected by transmission mechanism with electric rotating machine 4, and the electric rotating machine 4 drives claw
3 do axial-rotation, and the embroidering machine head 2 is arranged in vertical lifting bracket 6 by telescopic arm 5, and telescopic arm 5 drives embroidering machine head
2 move along a straight line, and the straight-line trajectory of embroidering machine head 2 passes through the center of rotation of embroidery frame body 1.
In the present embodiment, for the ease of programming Control, and the uniformity of taut frame tension force, described embroidery frame are improved simultaneously
Body 1 is circular taut frame.
In order to realize accurate embroidery, the electric rotating machine 4 is stepper motor, and decelerator is provided with electric rotating machine 4.
In the present invention, the vertical lifting bracket 6 includes lifting motor 61, vertical support 62, leading screw 63 and leading screw spiral shell
Mother 64, the leading screw 63 is vertically installed on vertical support 62 by bearing, and the feed screw nut 64 forms leading screw with leading screw 63
Pair, the telescopic arm 5 are arranged on feed screw nut 64, and the lifting motor 61 drives leading screw 63 to rotate.
