Description
Technical field
This utility model relates to field of textile machinery, particularly relates to the multiple needle positions sewing machine needle stand of a kind of fast changeable eedle.
Background technology
Sewing machine is a kind of textile machine common in life and production, general sewing machine is all single needle machine, single line sewing can only be met, but the product needing multi-line to sew along with industrial expansion gets more and more, single needle machine can not meet production needs, and this is accomplished by many eedles, owing to the variation of the circuit of product is accomplished by frequently changing eedle, and when changing eedle, dismantle loaded down with trivial details.
For the problems referred to above, existing solution such as Publication No. CN104878527A, the Chinese patent application of sewing machine needle stand of many eedles of entitled a kind of fast assembling-disassembling: it include eedle seat, female thread swivel nut, with externally threaded round outside but spuare inside sliding sleeve and fixing bar；Wherein, the bottom surface of described eedle seat is provided with glidepath；Described eedle seat is inserted with eedle slide block；Described eedle slide block can slide along glidepath and glidepath is stretched out in the bottom of eedle slide block；The bottom of described eedle slide block is provided with eedle mounting groove；Described eedle mounting groove is provided with eedle；The side at the two ends of described eedle slide block is provided with fastening screwed hole；Clamping screw is spun in the fastening screwed hole of eedle slide block through the side of eedle seat；Described female thread swivel nut is arranged on the surface of eedle seat；External thread rotary is passed through in the inner side of female thread swivel nut in the lower end of described sliding sleeve；The upper end of described sliding sleeve is fixed on head of sewing machine；The outside of the lower end of described female thread swivel nut is also rotary with swivel nut and fixes seat；Described fixing bar is located in female thread swivel nut and fixes with eedle seat and is connected；The middle reaches of described fixing bar are provided with boss；Described boss is folded in female thread swivel nut and swivel nut is fixed between seat, and is contacted with both respectively by ball；Described fixing bar is set to square slide bar on boss；Described square slide bar is located in sliding sleeve, to realize the purpose of fast assembling-disassembling multi-needle machine.
But eedle mounting groove is provided in the bottom of eedle slide block in the program, when eedle slide block is on eedle seat, eedle hole on eedle mounting groove is down, human eye need to be in below eedle mounting groove to be seen obliquely and could accurately see the position in eedle hole and then could install eedle, so too small being not easy in the visual field is installed, therefore eedle is installed every time and particularly needs the eedle by eedle slide block more renews after eedle seat is pulled down to reinstall again when reinstalling after eedle ruptures, eedle slide block is installed on eedle seat after installing by eedle the most again, the most sometimes eedle uses overlong time to be necessary for all changing eedle when re-using after needing cooling, so waste the time, have impact on production efficiency.
Have based on this, make the present invention.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide the multiple needle positions sewing machine needle stand of a kind of fast changeable eedle, and when changing and install eedle without demountor needle stand.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of multiple needle positions sewing machine needle stand of fast changeable eedle, including eedle seat and connection support, described eedle seat is chewing gum and bubble gum, the eedle installation portion parallel with cylinder axis is had on cylinder, some eedle installing holes are had on eedle installation portion, cylinder two ends are connected by bearing with being connected support, and have locking device to be fixed by cylinder on connection support.
Use said structure, when installing or change sewing machine needle, have only to unclamp locking device, rotate cylinder, eedle installation portion turns to the direction at setter place, and setter the most just can be seen eedle installing hole and easily be inserted in eedle installing hole by eedle, is rotated further by cylinder, making eedle straight down, locking locking device just can complete the installation to eedle or replacing.
It is further arranged to: on described connection support, there is through hole side, there is hole, 4 location described cylinder side, hole, 4 location is uniformly distributed around the axle center of cylinder, through hole with location bore dia identical and when position hole peak time with through hole concentric, described locking device is bolt, and through hole has, on hole, location, the female thread coincideing with bolt.
Use said structure, only need to rotate cylinder makes hole, location and through hole axle center be on same straight line, then is rotated in hole, bolt alignment location, just can lock cylinder, unclamp, only need to reversely rotate bolt, again still can lock after cylinder half-twist after unclamping.
It is further arranged to: the eedle installation portion number on described cylinder is 4, and eedle installation portion is uniformly distributed around cylinder axis line.
Use said structure, compare only one of which eedle installation portion, the efficiency changing eedle can be effectively improved, after changing sewing machine needle, only cylinder half-twist i.e. need to be can ensure that eedle direction straight down every time.
It is further arranged to: the axial line in hole, described location is positioned in the straight line at eedle installation portion place and the plane of cylinder axis composition.
Use said structure, it is ensured that having row's eedle installation portion to be in cylinder least significant end during locking cylinder, so, if this row's eedle installation portion is provided with eedle, then eedle must be straight down every time.
It is further arranged to: described bolt is butterfly-type bolt.
Use said structure, it is possible to increase the contact area of hands and bolt, when cylinder being locked and unclamps every time, hold that bolt tail is free-hand to be tightened and looser a bolt, it is not necessary to use other instruments, further shorten the needle exchange time, improve production efficiency.
It is further arranged to: on described connection support, have the scale graticule for auxiliary machine pin location.
Use said structure, can need to utilize scale graticule to carry out contact pin in eedle installation portion according to sewing scale.
Being further arranged to: connecting on described connection support has fixing bar, screw thread is arranged at fixing bar top.
After using said structure convenient replacing every time eedle, eedle seat height degree is adjusted.
It is further arranged to: described eedle seat, connection support and fixing bar are metal material.
Said structure is used to further ensure that the service life of this multiple needle positions sewing machine needle stand.
In sum, this utility model has the advantages that
1. when installing or change eedle, eedle installing hole can be made relative with operator by rotating the position of cylinder regulation eedle installation portion thus obtain the bigger operation visual field, and without eedle seat is dismantled, further increase the efficiency of needle exchange, in conjunction with sewing by multi-line, further increase production efficiency；
2. the symmetry two row's eedle installation portion on cylinder can be installed by eedle simultaneously, when row's eedle uses overlong time to need cooling, eedle seat can be rotated 180 ° and arrange the continuation operation of identical eedle with another, so it is used alternatingly, substantially prolongs the service life of eedle, reduce needle exchange number of times, thus improve production efficiency.
