Description
Technical field
The utility model relates to field of textile equipment, is specifically related to a kind of drafter.
Background technology
Spinning process system Pullin performances, be exactly for producing certain kind, spinning unit how reasonable layout drawing-off, plays each operation equipment technology economy, to realize the optimization of output supply and product quality, therefore a link important in Spinning process during draft apparatus.The equipment of existing French NSC company gets the nod, the drafter of its drafting system is two apron formula structures, it is made up of drawing-off top and drawing-off bottom, the drawing-off controlling wool top is extruded by centre, because the roller-way in drafter is fixed, large for different types of drawing of fiber adjustment difficulty, and the roller playing major impetus function is also integral type structure, operationally the most easily there are wearing and tearing in the axle core position of roller, roller after wearing and tearing can only integral replacing, the replacing price of import part is high, increases the use cost of equipment.
Utility model content
The purpose of this utility model is the above problem overcoming prior art existence, and provide a kind of drafter, the utility model has auto-adaptive controling ability, and changes simple, easy to maintenance, greatly reduces equipment use cost.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of drafter, comprise rubber enclosed and lower rubber enclosed, upper leather roller is disposed with in described upper rubber enclosed, three dancers, upper fixed roll and top roller, described upper leather roller, three dancers, the both sides of fixed roll and top roller are all fixed by support, the top of three described dancers is all abutted with support by spring, lower roller is disposed with in described lower rubber enclosed, lower fixed roll, metal saddle and bottom roll, described upper leather roller and lower roller are by two bearings, rubber peel roller shell, mandrel and gear connect to form, described rubber peel roller shell is set on mandrel, described rubber roller surface is provided with screw hole, described mandrel surface is provided with keyway, described screw hole is connected with keyway by screw, described mandrel two ends are positioned at two ends place inside rubber peel roller shell and are embedded with bearing, described gear is fixed on end, mandrel one end.
Further, support roller is provided with above fixed roller.
Further, described bearing is provided with care set.
Further, described gear is connected with actuating unit.
Further, the quantity of described screw hole is at least 2.
Further, described rubber roller is hollow cylindrical structure.
The beneficial effects of the utility model are:
1, the mandrel of upper leather roller and lower roller and rubber peel roller shell are the structure of detachable, ensure to be convenient for changing when mandrel wear, and retain the rubber peel roller shell without damaging, reduce the wasting of resources, dismounting is simple, and comparatively use the original-pack accessory of import, maintenance cycle is short, low price;
2, arranging of dancer can ensure, when different yarns fiber input drawing-off, by spring force rise and fall voluntarily, to realize, to the different active forces of fiber, reaching self adaptation.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment technology, be briefly described to the accompanying drawing used required in the description of embodiment technology below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is roller structural representation of the present utility model;
Fig. 3 is core shaft structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 3, a kind of drafter, comprise rubber enclosed 1 and lower rubber enclosed 2, upper leather roller 3 is disposed with in upper rubber enclosed, three dancers 4, upper fixed roll 5 and top roller 6, upper leather roller, three dancers, the both sides of fixed roll and top roller are all fixed by support 7, the top of three dancers is all abutted with support by spring 9, lower roller 10 is disposed with in lower rubber enclosed, lower fixed roll 11, metal saddle 12 and bottom roll 13, upper leather roller and lower roller are by two bearings 14, rubber peel roller shell 15, mandrel 16 and gear 17 connect to form, rubber peel roller shell is set on mandrel, rubber roller surface is provided with two screw holes, mandrel surface is provided with keyway, all be connected with keyway 19 by screw 18 in two screw holes 8, mandrel two ends are positioned at two ends place inside rubber peel roller shell and are embedded with bearing, gear is fixed on end, mandrel one end, gear is connected with actuating unit.
Wherein, be provided with above upper fixed roll and support roller 20, rubber peel roller shell is strutted, reserved enough mobile spaces are set to dancer.The outer ring of bearing closely abuts with rubber peel roller shell, and inner ring closely abuts with mandrel, and middle core ball portion is connected with care set 21, and care set can reduce wearing and tearing when mandrel rotates as support component.
The operation principle of the present embodiment is as follows:
During use, yarn fibers enters in drafter, lower rubber enclosed inside is fixed installation, so as the support of bottom, and is provided with self-adapting float roller in upper rubber enclosed, suitable drafting force can be ensured, actuating unit transmits power by gear, and mandrel rotates, because screw is tightly locked in keyway, so the transfer of rubber peel roller shell, the bearing of mandrel both sides is played a supporting role, and mandrel is arranged on the center of rubber peel roller shell, realizes the stationarity of rotating.
When wearing and tearing occur for bearing or mandrel, only need unclamp screw, beat mandrel one end, the bearing of opposite side can take out, and beats opposite side conversely, takes out another bearing, and maintenance time is fast, and part exchanging cost is low.
Because care set is projecting part, can be used as the support component supporting whole roller and use, such mandrel, when rotating, directly can not contact with mounting bracket, reduces wearing and tearing when rotating, and increases service life.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
