Description
Technical field
The invention belongs to clothes manufacturing equipment technical fields, are related to a kind of sewing machine, especially a kind of needle gage of sewing machine
It adjusts and automatic feeding structure.
Background technique
Sewing machine is formed one or more stitchings on sewing, is made one or more layers seam with one or more sewing thread
The machine that material interweaves or unites by a seam.Fabrics and leather, plastics, the paper such as function of sewing sewing cotton, fiber crops, silk, hair, staple fibre
Equal products, the stitching neat appearance stitched out, it is smooth securely, sewing velocity is fast, uses simplicity.Sewing machine is generally all filled by feeding
It sets, base, transmission and four part of attachment composition, is reasonably cooperated by the movement of each mechanism, cycle operation sutures sewing
Come.Sewing machine uses needle gage to adjust and fall automatically feeding sometimes in sewing process；Such as the flat seam machine in sewing machine exists
In the starting and ending stage of suture, reinforce sewing using backstitching when sewing.Needle gage adjustment structure in the prior art and automatic
Feeding structure will appear more serious parts depreciation and needle gage distortion situation after prolonged use, and send automatically
Biggish noise can be generated when material switching, brings puzzlement to sewing operation work.
Chinese patent (notification number: CN108611769A, publication date: 2018-10-02) discloses a kind of sewing machine, including
Needle gage adjusts stud, regulator shaft and the needle gage adjuster being fixed on regulator shaft, the upper end for the connecting rod of falling feeding and is connected to needle
Away from adjuster, the lower end for the connecting rod of falling feeding is connected in swing seat, and swing seat is swung by two positioning pins to be arranged on bottom plate,
It is provided with sliding slot in the middle part of the connecting rod of falling feeding, backstitches one end of spanner crank and sliding slot is slidably connected, the other end is pulled with backstitching
Hand axis connection backstitches wrench shaft and is connect by backstitching electromagnet crank with electromagnet is backstitched, and backstitched by backstitching solenoid actuated
Wrench shaft rotation, the middle part for the connecting rod of falling feeding or the middle part for backstitching spanner crank are connect by reset tension spring with bottom plate.
Change the angle of swing seat in above patent document in feeding distance in the front-back direction by adjusting stud, thus
Realize the change of needle gage；It drives swing seat to be rocked to certain angle realization by the group of falling feeding rod automatically to backstitch, due to backstitching needle
