Abstract
The thread take-up mechanism of thickness variable sewing needle bar includes one installation rack with one transverse installing shaft and one thread clamping spacer and one thread clamping nut to form one thread gap in between; one transversely sliding rod with two limiting rings and one thimble in the head; one shifting block hinged to the rack for shifting the thread clamping spacer and one tension spring to connect the shifting block to the sliding rod; and one wedge block to push the sliding rod to slide and fixed on the frame of sewing machine in the location corresponding to the lowest position of the sewing needle. The present invention completes the complicated mechanical operation of varying sewing thickness and increasing the needle stroke.
Description
(1) technical field
The present invention relates to a kind of sewing needle rod wire selecting mechanism, relate in particular to a kind of thickness changing sewing needle rod wire selecting mechanism.
(2) background technology
Sewing machines was mainly used in apparel industry in the past, and the object that is sewn generally all is that varied in thickness is little uniformly.But when the sewing object was the footwear base, common sewing device can't satisfy.It is out-of-shape not only, and sewing varied in thickness big (when sewing footwear base, sewing needle is thrust by the side of footwear base), certainly will cause the difference of each take-up amount.Such as the charging from left to right of footwear mould, the take-up amount changes from less to more, and so for common Sewing machines, its take-up amount is equal to, and therefore can't realize.Sewing work to varied in thickness complexity, specific (special) requirements that the eedle stroke is big can only be finished by manual at present.And handspin efficient is low, stitching is of poor quality, labour intensity is big.
(3) summary of the invention
In view of finishing by manual at present at present to the sewing work of varied in thickness complexity, specific (special) requirements that the eedle stroke is big, the invention provides a kind of thickness changing sewing needle rod wire selecting mechanism, reach the moderate equilibrium of thread tension, suitable, the stitching neat appearance of elasticity by changing every pin take-up amount, and realized mechanized operation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of thickness changing sewing needle rod wire selecting mechanism, comprise mounting bracket, be fixed with the installation shaft of horizontally set on the described mounting bracket, described installation shaft is provided with thread clamping spacer and tension regulating thumb nut, described thread clamping spacer is set on the described installation shaft slidably, described tension regulating thumb nut and described installation shaft are affixed, described thread clamping spacer and tension regulating thumb nut all are positioned at the outside of described mounting bracket, described thread clamping spacer is positioned at the inboard of described tension regulating thumb nut, forms the threading slit between thread clamping spacer and the tension regulating thumb nut; Be equipped with the slide bar that can laterally slide on the described mounting bracket, described slide bar is positioned at the below of described installation shaft, slide bar between the mounting bracket dual-side is provided with two on-slip bulge loops, the head of described slide bar is provided with thimble, and described thimble and described thread clamping spacer, tension regulating thumb nut are positioned at the homonymy of described mounting bracket; Also be hinged with the shifting block that is used to stir described thread clamping spacer on the described mounting bracket, described shifting block is between described installation shaft and slide bar, and described shifting block is connected by extension spring with described slide bar;
Comprise also being used to contact described slide bar so that the voussoir that slide bar slides that described voussoir is fixed on the sewing machine frame and to move to the position of minimum point corresponding with sewing needle, meet to described slide bar afterbody on the inclined-plane of this voussoir.
Further, the outer side edges of described mounting bracket also is provided with second thimble, the 3rd thimble, the thimble of this second thimble, the 3rd thimble and described slide bar head is positioned at the homonymy of described mounting bracket, and described slide bar is between described second thimble and the 3rd thimble.
During sewing, sewing needle rod wire selecting mechanism is installed on the shank and moves in company with shank, and needlework are at first walked around the threading slit, and then pass thimble and draw.Down during pricker, slide bar moves to the limit toward caudal directions and is located by the on-slip bulge loop, and shifting block leans against on the mounting bracket side away from thread clamping spacer, breaks away from thread clamping spacer, is in the line sending state this moment.When needle movement arrives minimum point, the slide bar tail end is installed in the cephalad direction of the voussoir top of relevant position to slide bar, when the position parallel with shifting block crossed in the extension spring campaign, extension spring pulls to the slide bar cephalad direction with shifting block and withstands thread clamping spacer and make thread clamping spacer and tension regulating thumb nut close tightly to clamp line, and this moment, line was by locked.Line is by after locked, and line and pin hole do not have relative motion, so pin is in backhaul, and just that last pin is unnecessary naturally line amount is regained.When line is all regained, be in tensioning state, when the tension force of line enough spurs slide bar, make slide bar toward its caudal directions motion, when the extension spring campaign was crossed with the shifting block parallel position, extension spring pulled to the slide bar caudal directions with shifting block, thread clamping spacer is unclamped, thereby enters the line sending state once more.
Beneficial effect of the present invention is: realized the mechanized operation of the sewing work of varied in thickness complexity, specific (special) requirements that the eedle stroke is big, reached the moderate equilibrium of thread tension, suitable, the stitching neat appearance of elasticity by changing every pin take-up amount.

Fig. 2 is the structural representation of the present invention when being in take-state.
(5) specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Embodiment one
With reference to Fig. 1, Fig. 2, a kind of thickness changing sewing needle rod wire selecting mechanism, comprise mounting bracket 1, be fixed with the installation shaft 2 of horizontally set on the described mounting bracket 1, described installation shaft 2 is provided with thread clamping spacer 3 and tension regulating thumb nut 4, described thread clamping spacer 3 is set on the described installation shaft 2 slidably, and described tension regulating thumb nut 4 and described installation shaft 2 are affixed.Described thread clamping spacer 3 and tension regulating thumb nut 4 all are positioned at the outside of described mounting bracket 1, and described thread clamping spacer 3 is positioned at the inboard of described tension regulating thumb nut 4, form the threading slit between thread clamping spacer 3 and the tension regulating thumb nut 4.
Be equipped with the slide bar 5 that can laterally slide on the described mounting bracket 1, described slide bar 5 is positioned at the below of described installation shaft 2, slide bar 5 between the mounting bracket dual-side is provided with two on-slip bulge loops 6, the head of described slide bar 5 is provided with thimble 7, and described thimble 7 and described thread clamping spacer 3, tension regulating thumb nut 4 are positioned at the homonymy of described mounting bracket 1;
