Description
Technical field
The utility model relates to a kind of cotton spinning spun yarn V-type drawing-off cup spring weight cradle, the improvement structure of pressing mechanism behind particularly a kind of V-type drawing-off cup spring weight cradle.
Background technology
Cotton spinning industry has in recent years proposed the raising drafting multiple, spin workload before the minimizing, reinforcement back zone fiber is controlled the new concept with the high-quality and high-efficiency draft process that improves yarn quality, each frame manufacturing enterprise has released V-type drawing-off fine spining machine and V-type drawing-off pressurized cradle one after another, the extremely user's favor of particularly a kind of V-type drawing-off cup spring weight cradle, as shown in Figure 1.
But also there are many weak points in this V-type drawing-off cup spring weight cradle:
One, be subjected to the influence of back pressing mechanism design, the maximum drafting of reel cage spaces and is restricted, and makes reel cage spinning suiting fibre length be subjected to limitation.
Two, the leaf spring of back pressing mechanism is designed to " R " shape, and leaf spring local deformation degree is bigger, and leaf spring pressure is failed easily, has influenced the leaf spring life-span.
Three, the back is not designed pressing mechanism on the pressing mechanism directly to the back datum mark of bottom roll (spacing) size adjustment, but by adjusting the relative size that guarantees when top roller spaces between bottom roll and the back pressing mechanism, and can the whether accurate design pressure value that directly relates to back pressing mechanism of this size really put in place.The force value deviation of pressing mechanism is very big behind the reel cage that adjusts under the situation that does not find directly effective datum mark.
The utility model content
Be to provide the improvement structure of pressing mechanism behind a kind of V-type drawing-off cup spring weight cradle order of the present utility model, leaf spring is designed again, make two bending part corners of leaf spring bear 1/2 distortion separately, make the stress that is born on the leaf spring unit are reduce one times, improve the anti-ageing ability of moving back of leaf spring, prolonged service life; On flat spring bracket, be provided with datum hole in addition, make the relative size that pressing mechanism arrives between the bottom roll of back after regulating promptly accurately convenient again.
For achieving the above object, the utility model has adopted following technical scheme:
The improvement structure of pressing mechanism behind a kind of V-type drawing-off cup spring weight cradle, entire mechanism comprises that support, leaf spring, top roller grip seat and steady pin, leaf spring head and support fasten, the leaf spring middle part is positioned on the support by steady pin, the leaf spring afterbody is connected with the gripping seat, and it is characterized in that: described leaf spring is " S " type.
Above-mentioned top roller grips seat and is formed by the polymer manufacturing with favorable elasticity, and its tail end is provided with a rectangle the region between the heart and the diaphragm hole, and its bottom one connection is provided with a folder spring.
Above-mentioned " S " template spring two sides of tail is provided with locking tooth, and it can grip seat tail end blind hole with top roller and form interference fit.
Above-mentioned " S " template spring head both sides are provided with two groups of lugs, and two groups of open slots that are provided with on itself and the support fasten.
Upper shed groove in two groups of open slots of above-mentioned support is " 7 " font.
The side of above-mentioned support is provided with and is used to adjust the datum hole that top roller spaces.
Above-mentioned support bottom is provided with one group of fixed pin holes.
Two lugs with leaf spring during installation snap in the support square groove by rotation leaf spring angle with it, and subsequently to the leaf spring precharge pressure, with the fixed pin holes of leaf spring steady pin insertion support, the locking tooth one end aligning of last leaf spring gripping seat oblong aperture is forced into and gets final product.
The utility model is designed to leaf spring on " S " type, makes the corner of its two bending part bear 1/2 distortion separately, makes the stress that is born on the leaf spring unit are reduce one times, has improved the anti-ageing ability of moving back of leaf spring, has prolonged service life.In conjunction with the leaf spring special geometry flat spring bracket is improved simultaneously, the maximum drafting that has increased this pressing mechanism spaces, and makes the longer fiber of reel cage energy spinning suiting.In addition the side of flat spring bracket be provided with one with bottom roll same plane, back on datum hole, make that to regulate the back pressing mechanism promptly accurately convenient again to the relative size between the bottom roll of back.
In addition, for solving the difficult problem that " S " template spring and top roller grip seat inconvenience riveted joint, improve gripping seat, form by polymer manufacturing with favorable elasticity, and one rectangle the region between the heart and the diaphragm hole is set at its tail end, this blind hole can form interference fit with the locking tooth that the leaf spring two sides of tail is provided with, and only locking tooth one end need be forced into blind hole when assembling and can realize being connected.In addition, will grip seat and be designed to one, reduce material material cost, reduce manufacturing procedure with the folder spring.
