Description
Technical field
The utility model belongs to rotating shuttle technical field, relates in particular to a kind of in order to be wound around the novel peg or spindle of bottom line.
Background technology
Although the pattern of modern Sewing machines is various, for family and various special industrial production application, but general principle there is no change, in these Sewing machiness, have and do the suture needle pumping and make thing with needle thread passing, and rotate the entrained bottom line of the rotating shuttle (shuttle) of (waving) motion and interlock mutually and make to make thing sizing making to do below thing.
Its outer wall of the winding section of common peg or spindle is smooth structure, contacting between the peg or spindle axis hole (smooth structure) of peg or spindle and the fixed leg of rotating shuttle, when work, rotating shuttle fixed leg is located in the peg or spindle axis hole of peg or spindle and is rotatedly connected, and because the contact-making surface between peg or spindle axis hole and fixed leg is larger, therefore can produce larger frictional resistance, thereby make the elasticity of bottom line bottom line in the time of outlet inhomogeneous, in addition, the poor stability of peg or spindle running, has reduced embroidery quality virtually; For this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of Shuttle bobbin of sewing machine [application number: 201020223271.0], comprise a core, core is provided with an axis hole running through vertically, formation the first bead and the second bead that the two ends of core are radially outward expanded, form the storage area that can hold bottom line between this two bead and core; This peg or spindle has a matsurface that is formed at the increased frictional force of core periphery.
Although such scheme has been alleviated the problem that bottom line easily skids to a certain extent, but complicated integral structure, manufacturing cost is high, on the other hand, in use the contact-making surface between peg or spindle axis hole and the rotating shuttle fixed leg of peg or spindle is larger, in the time of operation, frictional resistance is larger, stationarity while virtually having reduced peg or spindle running, secondly, the elasticity of bottom line bottom line in the time of outlet is inhomogeneous, embroidery poor quality, in addition, its manufacturing cost of existing peg or spindle is higher and production efficiency is low (entirety is manufactured), can not adapt to the production requirement of current enterprise.
