The present invention will be described in detail below with reference to the accompanying drawings and embodiments creates.
In some embodiments, the sewing machine with retainer height adjustment device, regulating device C be located at supporting table A and
Between sewing machine main body B, including pedestal 1, elevating mechanism 2, retainer mechanism 3 and lifting frame mechanism 4, the pedestal 1 and the seam
Owner's body B that threads is structure as a whole connection, and the retainer mechanism 3 is fixedly connected with the lifting frame mechanism 4, the elevating mechanism 2
It drives the lifting frame mechanism 4 and the retainer mechanism 3 to go up and down positioning, is between the supporting table A and the sewing machine main body B
It is plugged and fixed.
In some embodiments, the retainer mechanism 3 is located at 1 middle part of pedestal, and the retainer mechanism 3 includes by crank
Connecting rod drives the feed dog 31 of movement, and the structure of the retainer mechanism discloses in patent CN201721868050.7, no longer superfluous
It states, in the present embodiment will a retainer shell 32 be set outside the retainer mechanism 3, retainer mechanism 3 is located in the retainer shell 32.
In some embodiments, the lifting frame mechanism 4 includes frame body 41, guide plate 42, windowing 43,44 and of fixing bolt
Compressed spring 45, the frame body 41 are N-shaped frame, are equipped with several windowings 43 in the middle part of the horizontal edge of the N-shaped frame, and the feed dog 31 is by this
It is several windowing 43 in stretch out, two pieces of guide plates 42 are structure as a whole with the horizontal edge of the frame body 41 to be connect, and with the frame
The vertical edge of body 41 is arranged parallel, this two pieces guide plates 42 are located at the two sides of the retainer mechanism 3, on the pedestal 1
It is correspondingly provided with guide groove 11, the guide plate 42 is located in guide groove 11, and goes up and down in the guide groove 11；The frame body 41
Vertical edge bottom be equipped with perpendicularly inward bending part 411, the bending part 411 is equipped with several jacks, and fixing bolt 44 passes through
It is screwed and connect with the threaded hole of the pedestal 1 after compressed spring 45 and jack, it is curved under the pressure effect of compressed spring 45
411 lower surface of folding part is disposed proximate to 1 upper surface of pedestal.
The retainer shell 32 is located at 41 lower section of frame body, and is fixedly connected with the frame body 41 by screw.
In some embodiments, the elevating mechanism 2 includes that the double link 22 moved forward and backward is driven by servoBcylinder 21, each
The free end of the connecting rod 22 is equipped with a wedge block 23, and N-shaped frame bottom surface is one oblique close to the part of the servoBcylinder 21
Face forms wedge groove 24 between the inclined-plane and the base upper surface.
During the wedge block 23 is inserted into wedge groove 24, the frame body 41 rises, bending part 411 and retainer machine
Structure 3 rises together, and then compresses compressed spring 45；

The height of frame mechanism and retainer mechanism is dropped, adjusts the height of the relatively upper presser feet 5 of retainer mechanism as a result,；Specifically, when cloth is thicker
When, servoBcylinder drives connecting rod to move backward, and by extracting out in wedge groove, frame body and retainer shell move down wedge block, upper presser feet 5
Spacing between feed dog becomes larger；When cloth is relatively thin, servoBcylinder drives connecting rod to move forward, and wedge block is inserted into wedge groove,
Frame body and retainer shell move up, and the spacing between upper presser feet and feed dog becomes smaller.
The thickness measurement sensor can be fixed on the side of supporting table by c-type frame.
The controller can be located on the lower surface of supporting table.
In some embodiments, controller control manipulator 6 realizes the operation of straight line work feed, curve work feed, specifically, needs
One manipulator 6 is set in the two sides of head of sewing machine 7, respectively to accurately control the work feed path after sewing preceding and sewing；The control
Device processed is PLC.
Above an embodiment of the invention is described in detail, but the content is only the invention
Preferred embodiment should not be considered as limiting the invention the practical range of creation.It is all to be made according to the invention application range
All the changes and improvements etc., shall remain within the patent scope covered by the invention.
