Description
Technical field
The utility model belongs to the knitting mechanism technical field, is specifically related to a kind of shog mechanism of computer plain flat knitter
Background technology
such as industry the reason of knowledge; Computer plain flat knitter has such as the capable braiding of automatic meter, add and subtract pin automatically, move yarn certainly, the function of automatic needle-turning etc. when barring-on and cross-stitch work automatically; In order to ensure that knitting mechanism weaves smoothly; Therefore be equipped with shog mechanism, mechanism makes shog by shog.For example when braiding cross-stitch work fabric, coil is moved on the knitting needle on the needle-bar that is positioned at opposite side from the knitting needle (side of needle-bar such as the knitting needle on the preceding needle-bar) of a side; And need stagger sometimes one piece or plural number piece knitting needle, thereby need realize by relatively move (traversing) of needle-bar.This situation of shog is more common during for braiding such as the braided fabric of the twisted shape style in the being seen food of daily life.
The mobile range of needle-bar is corresponding bigger in the computer plain flat knitter braided fabric process of
low plane No.; The notion of so-called low plane No. is: plane No. is the computer plain flat knitter of E3, and E3 representes that the knitting needle number in per 25.4 ㎜ length is 3 pieces on the needle-bar.
The TECHNICAL INFORMATION SOURCES of shog mechanism can be seen in
in disclosed Chinese patent document, for example utility model patent Granted publication CN2663466Y recommends that " the shog mechanism of controlled flat knitting machine " arranged, although this patent scheme has been concluded many technique effects at the 1st page of inverse the 7th to countdown line 3 of its specification; But shortcoming below objectively existing: one of which; Be not enough to satisfy the braiding rate request, move because the patent scheme only shows as preceding needle-bar, then needle-bar then is static; Promptly do not move; As aforementioned because the needle gage of the needle-bar of the computer plain flat knitter of low plane No. big (knitting needle in 25.4 ㎜ length is merely 3 pieces), therefore before needle-bar to move the required time longer; The computer plain flat knitter that can't at full speed require adapts, and certainly will influence production efficiency; Its two, the technology contents of patent scheme unexposed make zero level detecting apparatus and needle-bar shifting quantity detecting device and so on.And for example utility model patent Granted publication CN201106088Y discloses " computer needle adder shog controlling organization ", and there is the shortcoming of last patent equally in this patent scheme.Utility model Granted publication CN201198518Y provides " transverse transmission device of computer plain flat knitter " for another example; This patent scheme is to propose to the traversing of the head of knitting mechanism, does not therefore have referential meaning technically for needle-bar traversing.
