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.However planar defect in the presence of existing arm-type sewing machine in the market: first, due to existing cylinder
The cloth feeding mechanism of formula sewing machine uses the tooth lifting cam and feed lifting fork structure of high secondary motion, and core structure to lift at tooth
Space very little, not only feed lifting fork thickness is defined, and the stress point of the sewing machine is just in the higher pair junction so that
The feed dog frame two or three months of the sewing machine just need replacing, and improve production cost；Second, using manually daily injection
The mode of lubricating oil cannot steadily control volume read-out, easily cause it is each need lubricating component lubrication it is insufficient, lead to machine run
Speed does not increase, and running gear high speed is also easily caused to kill；Third, needle space standard plate is using 60 ° of taper metallic pins and bidding quotation tooth
Fixed form, since the tooth form of plastics bidding quotation is prone to wear, cause to sew thick material when, needle gage screw bolt loosening, needle gage is unstable, shadow
Ring sewing quality；Fourth, using manually mode to each peg or spindle pre-wound baseline, it is cumbersome, it is time-consuming and laborious；Fifth, existing
There is sewing machine generally to use Single button tension disk, since its clamping force is limited, need to twist tension disk when sewing sometimes is very tight,
If clamp spring is chronically under overload pressure state, easily cause tension force of facial suture unstable, causes sewing thread trace unstable, sternly
Ghost image rings product quality.
