Abstract

The utility model relates to an aluminium alloy cloth guiding roll, which comprises a cylinder roll body, wherein, both ends of the roll body are respectively provided with a rotating shaft; the rotating shafts are penetrated through center holes of a supporting cover, and are fixedly connected with the center holes of the supporting cover; the supporting cover is arranged in the cylinder roll body and is fixedly connected with the inner wall of the cylinder roll body. The utility model is characterized in that the center part of the inner part of the roll body is also provided with a polygon hole. One end of the rotating shaft is formed into a polyhedron which is corresponding to the polygon hole, and the polyhedron can be embedded into the polygon hole. The utility model can be made of aluminum alloy materials. The utility model has the advantages that the manufacturing process is shortened, the weight of the cloth guiding roll is lightened, the equipped capacitor of a mechanical driving motor is reduced, the energy consumption is lowered, the maintenance and the repair are convenient, etc.

Description

A kind of aluminium alloy fabric guide roll

The utility model relates to a kind of textile machine, particularly a kind of aluminium alloy fabric guide roll.

At present, fabric guide roll has various ways such as chromium plating fabric guide roll, stainless steel fabric guide roll, the outer coating stainless steel pipe fabric guide roll of carbon steel pipe in the prior art, but in use all has certain defective.The chromium plating fabric guide roll is acid-alkali-corrosive-resisting not, and chromium coating comes off easily.The stainless steel fabric guide roll is to roll into roll body with the 2mm corrosion resistant plate, is pressed into supporting lid (silently) at the two ends of roll body, and the car system polishing of welding back forms.For excircle dimension and the roundness that guarantees deflector roll, need to eliminate crator, adopt rumble system technology, manufacture process is longer like this.Simultaneously,, easily produce down in long-term uniform load (fabric tension) effect and to be out of shape, problems such as that the deflector roll after the distortion is prone to when converted goods is wrinkling, sideslip because of deflector roll is that the 2mm thin plate rolls.The outer coating stainless steel pipe fabric guide roll of steel pipe, what great majority adopted all is inside and outside layer roll bending, what skin coated is corrosion resistant plate, make its ectonexine be close to and do not shell with the method for rumble system then, two ends are pressed into supporting lid (silently), and the car system polishing of welding back forms, and its processing technology is comparatively complicated, the roller deal is heavier, thereby mechanical output consumption is increased.

The purpose of this utility model is to overcome defective of the prior art, and a kind of aluminium alloy fabric guide roll is provided, and shortens machining process, alleviates the weight of fabric guide roll, thereby reduces the installed capacity of the driving motor of machinery, reduces its energy consumption.

To achieve these goals, the utility model has adopted following technical scheme:

In comprising the aluminium alloy fabric guide roll that is made of the cylinder roll body, these roll body two ends are equipped with turning cylinder respectively, and this turning cylinder passes supporting and cover centre bore and fixedly connected with it, and it is interior and fixedly connected with its inwall that the supporting lid is inserted the cylinder roll body.Central authorities also are equipped with a polygonal hole in the roll body, and an end of turning cylinder is set to and the corresponding polyhedron of this polygonal hole, and can embed in this polygonal hole.

Owing to adopted technique scheme, the utility model can be made of aluminum alloy materials, shortens process, alleviate fabric guide roll weight (only for be laminated with pipe fabric guide roll weight 22%), reduce the installed capacity of the driving motor of machinery, cut down the consumption of energy, and maintain easily and keep in repair.

The utility model will be further described below in conjunction with accompanying drawing and embodiment.

Fig. 1 is the utility model structural representation;

Fig. 2 be among Fig. 1 A-A to cutaway view;

Fig. 3-Fig. 7 is the embodiment of other several conjoined structures in the utility model roll body.

With reference to Fig. 1, the utility model is equipped with a cylinder roll body 3, and this roll body 3 is made by aluminum alloy materials, and extrusion stretching is shaped after heating, and the cylindrical roundness of roll body 3 and roll body 3 bus nonstraightness are all controlled when being shaped.Therefore, this roll body 3 does not need to process after shaping again, and only required roll body 3 amplitudes of cutting get final product on the section bar that stretches.

Be equipped with turning cylinder 1,4 respectively at the two ends of roll body 3, because of the structure at two ends is identical, the existing structure of only narrating the one end.This turning cylinder 1 usefulness stainless steel is made, and it passes supporting and covers 2 centre bores and fixedly connected with it.Turning cylinder 1 is equipped with dovetail groove 1.1 with the joint portion that 2 centre bores covers in supporting, and supporting cover and also is equipped with corresponding projection 2.1 in 2 centre bores, and this projection 2.1 is embedded in formation turning cylinders 1 in the groove 1.1 mutually and covers 2 fixedly connected with supporting.

Supporting cover 2 and is inserted in the cylinder roll body 3 by excessive cooperation, and will support cover 2 and roll body 3 inwalls weld and fix.

With reference to Fig. 2, the utility model central authorities in roll body 3 also are equipped with a polygonal hole 5, and an end of turning cylinder 1 is set to and this polygonal hole 5 corresponding polyhedrons 1.2, and can embed in this polygonal hole 5.The polygonal hole 5 of central authorities can be set to rectangular opening in this roll body 3, and an end of turning cylinder 1 can be set to and the corresponding four prisms cylinder of this rectangular opening.Present embodiment is that central authorities are set to a square hole in roll body 3, and an end of turning cylinder 1 is set to and the corresponding four-prism of square hole.It is more safe and reliable that said structure transmits moment of torsion when making the utility model work, stable performance.

In order to guarantee that roll body 3 in use has enough anti-twist intensity, also is provided with the disjunctor 6 that is connected with roll body 3 inwalls and central polygonal hole 5 in roll body 3.With reference to Fig. 3-Fig. 7, this disjunctor 6 can be arranged to various as shown in drawings structures, makes every effort to reach in unit length the weight of minimum, and maximum the moment of inertia can be arranged simultaneously.
