Description
Technical field
The present invention relates to field of textile machinery, relate in particular to a kind of up-coiler repiece switching mechanism.
Background technology
In industry, the filament plate that moves down of conventional up-coiler is repiece and the skateboard that switches use at present.According to repiece whipping constructional feature, whipping action during the moving down filament plate and be responsible for repiece and switch of every up-coiler: repiece at present threading end bar is fed into fixed position silk, moves down filament plate and does longitudinal travel, and tow is squeezed in paper tube tailfiber notch.Because move down the slideway of filament plate, adopt axial straight design, during switching, tow speed is higher, and relative tension is larger; The cornerite that tow forms on paper tube is larger, and the success ratio of repiece and switching is also high.Yet, the problem that this design exists is embodied in: during repiece, the complete out of reach of speed of suction gun aspirator is synchronizeed with winding speed, cause relative winding tension lower, tow can not form good cornerite on paper tube, the too little or tow of cornerite does not form tension force to the paper tube of upper folder, and while moving down filament plate action, can be got to paper tube tailfiber notch outside for tow, causes repiece failure.If cornerite is too large, silk when move on the paper tube of upper folder, and friction force or shearing force are too large, moves down filament plate and also silk is not moved on to tail fibre groove and just broken during switching, makes too repiece failure.So in this structure, make cornerite be controlled at 2 degree left and right and could guarantee to greatest extent repiece handover success rate, even like this, repiece handover success rate is also only in 80-90% left and right, worker is just directly beaten tailfiber on paper tube, tailfiber is unintelligible to be caused preoriented yarn to add can not to cross smoothly pipe man-hour, cause its tailfiber to cross tail success ratio very low.
As improvement, current many up-coiler users change secondary into and have switched repiece switching operation: worker directly beats tow the object that reaches a repiece in the gap of paper tube and two paper tubes with suction gun, and then carries out secondary switching.
But main drawback or consequence that secondary switches are:
1) waste silk can be entangled between chuck and paper tube, causes the mechanical breakdowns such as pushing cylinder fault;
2) the remaining waste silk on repiece paper tube is for the first time sliced off with cutter, inevitably can partly hurt paper tube, if this paper tube continues use can cause following process time, bottom unwinding is bad; As directly abandoned and can causing waste;
3) if the waste silk of repiece sops up with suction gun for the first time, both consumed energy, again waste of manpower;
4) each repiece can produce a large amount of waste silks, causes cost to rise.
Summary of the invention
The object of this invention is to provide and a kind ofly can improve repiece handover success rate, reduce waste silk amount, without the up-coiler repiece switching mechanism that carries out secondary switching.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of up-coiler repiece switching mechanism, comprise and move down filament plate and shovel board, described shovel board is provided with slideway, the described filament plate that moves down is provided with the slide head coordinating with described slideway, described filament plate one side that moves down is provided with for hooking the groove of wire drawing bundle, and described slideway has towards the rightabout bend of groove one side.
Further, in described slideway, be provided with for supporting the bearing of slide head.
Further, the bent angle of described bend is 120 degree.
Advantage of the present invention and beneficial effect:
Up-coiler repiece switching mechanism provided by the invention, 1) moving down the action of filament plate in shovel board becomes axle shifted laterally.While moving axially, the cornerite that tow forms on paper tube is less, and when tow moves on paper tube, friction force is very little; And during shifted laterally, the cornerite that tow forms on paper tube increases, tow tension increases, move down filament plate to be easy to tow to get to tailfiber notch, thereby reach a repiece success and the good object of tailfiber; 2) slide head that moves down filament plate has increased bearing, not only make to move down filament plate moves more happy in slideway, wear and tear less, life-span is longer, and what is more important, because the slideway wearing and tearing in shovel board are very little, move down the stability-of-path that filament plate moves in slideway, operation precision is high, and the cornerite that tow forms on paper tube is stable, and the success ratio of accurately getting to tailfiber notch improves.
By up-coiler repiece switching mechanism provided by the invention, can greatly reduce waste silk amount, improve the quality of products simultaneously.Because improvement cost is very low, be also suitable for large application scope.
