Abstract
The aim of the invention is to simplify the construction and production of drawing assemblies in spinning machines. To achieve this, the bearing housings (7) of at least the bottom rolls (1, 2 and 3) of the drawing assembly are retained in a profiled section (11), which comprises recesses for the bearing housings (10) that are located at a given fixed mutual distance. There is thus no need for adjustable carriages that hold the bearing housings (7). The profiled section (11) can be configured from a sheet metal U-section that is open on the underside, or as a drawn or rolled section that is open on the underside or has the form of a box.
Description
The present invention relates to a kind of device that is used to support the bottom roll of cotton mill frame drafter, can use cotton mill of the present invention frame is thick spinning machine and spinning machine.
The bottom roll of cotton mill frame drafter is bearing in the so-called roller carriage usually, these roller carriage great majority are made up of the tabular foundry goods with inclined guide surface, have a plurality of so-called slides that are used to hold the lower Roller bearing body to slide on these foundry goods and can fix.Slip by these slides makes the mutual spacing of bearing position and the width of the draw zone that therefore is made of bottom roll all can change, and what especially can be matched with the material that will stretch by drafter pulls sample length.
Be that the spigot surface roller carriage or slide all must carefully carefully be processed, slide and slide is adjusted accurately so that can realize easily.Must have in addition slide is fixed in device on the assigned position on the roller carriage.
Task of the present invention is to simplify the supporting of drawing rollers in the frame of cotton mill greatly.On the frame of many cotton mills, just fix necessary draw zone width, the mutual spacing of drawing rollers just for this reason from the outset, do not allow to adjust.Therefore the slide adjusted that does not just need to be used to place the drafter supporting device.The bearing that exactly can not adopt adjustable bearing slider and will be used for these supporting devices is directly arranged in the parts of bearings.This just can be designed to the position of the residing frame at least of these bearings shaped body easily that be shaped and that will process.Here under a stable condition even can not adopt separately roller carriage.
By US 3,035, though 314 cicadas make the position of the described slide of supporting of roller carriage the plate system section bar of U-shaped.But the bearing slider of bottom roll can lead slidably as before on this plate system section bar.That is to say that this patent thinks: can abandon the adjustable of bottom roll and can not utilize the advantage of not establishing the slide band.
(also known in 76c 12/05 grade in March 5 nineteen fifty-one) discloses a kind of roller carriage that is used to support the drafter bottom roll in German patent application K 295 (on October 29th, 1949), and this roller carriage is the U-shaped section bar that opens wide downwards.But this roller carriage is not directly used in the supporting bottom roll, but the supporting roller is right, bottom roll can these rollers on roll.Therefore this solution generally requires to have the position of bearings of double amount with respect to the direct supporting of bottom roll.
The carriage that is used for bottom roll with nonadjustable position of bearings is by US 2,592,718 cicadas just.The inventor of this patent but do not recognize: abandon adjustable and just the bearing portion of roller carriage can be made inexpensive section bar or the die casting of making by plate.
In view of the above, the invention is characterized in the feature described in the independent claims.They are related to the bearing body that holds bottom roll and definite position.If should maybe cannot not abandon a kind of roller carriage, this roller carriage can at random be shaped in its all the other positions and construct so.
For the described position that is used for holding the bottom roll supporting mass, preferably adopt a kind of semi-finished product of inexpensive easy processing, as the plate of U-shaped bending or the die casting section bar of stretching, wherein can draw the necessary groove of system easily.
The groove of regulation advantageously forms with the mutual spacing milling in shaped body with the bottom roll regulation.Shaped body is advantageously removable, thereby if it is worth changing the mutual spacing of bottom roll exceptionally, so just can change another kind of shaped body, and it has the groove of the system of drawing with desirable spacing.
Accompanying drawing illustrates the perspective view of one embodiment of the present of invention.It has represented the part of a drafter of big length.
Accompanying drawing illustrate a kind of have three rollers to input bottom roll 1, middle bottom roll 2 and the output bottom roll 3 of the typical spinning machine drafting mechanism of the little band in bottom.The self-evident top roller of being furnished with unshowned pressure-loaded here of driven bottom roll, this top roller and bottom roll constitute roller to being used for the drawing of fiber yarn.The part of other operation of drafter is slubbing guide 4 and the little band commutation in bottom guide rail 6 that is fixed on vertical movably slubbing guide guide rail 5, and the little band in the bottom of herein not expressing is around this commutation guide rail guiding.
Obviously, the present invention also can have other structure, that is to say that to have three right with top roller, do not have to implement on the drafter of little band or the like.
Bottom roll 1,2 and 3 is bearing in 7 li of bearing bodies that comprise rolling bearing, and the latter is fixed in its position by bearing cap 8.Bearing cap 8 is provided with grease fitting 9, can inject grease by this grease fitting.
Bearing body 7 is positioned at 10 li of the grooves of coupling, and this groove comes out in that 11 li of shaped bodies are processed.This obform body is made up of a kind of U-shaped section bar of being made by plate that opens wide downwards in institute's diagrammatic sketch.Such as mentioned above, as also can to use U-shaped stretching or that roll volume or box-shaped to seal section bar without plate.As will be seenly also be processed with groove 12 or 13 11 li of shaped bodies and be used to place the little band divert guide track 6 of slubbing guide guide rail 5 and bottom.
Draw system fastener hole 15 14 li of two connecting plates of shaped body 11, on the supporting section that the correspondence that makes shaped body can be fixed on cotton mill frame frame by means of these holes is arranged.These supporting sections can be made up of a residue section of roller carriage, and this roller carriage then becomes complete by shaped body 11.But also the other parts of frame can be designed to receive the supporting section of shaped body, thereby just no longer include real roller carriage.Also clearly be that shaped body 11 also can assemble with the mode that is different from by fastener hole 15 equally.
Obviously, shaped body 11 is arranged with the mutual distance that mostly is six or eight spinning positions greatly as common roller carriage.
