Description

A kind of double-layer high strength deflector roll

Technical field

The utility model is related to a kind of double-layer high strength deflector roll, belongs to deflector roll processing technique field.

Background technology

Existing is usually that the roll body that thickeies deflector roll is realized to overlength deflector roll that length, intensity are required, to meet overlength Or the requirement of high intensity, the wall thickness of the roll body of deflector roll wants more than 10mm, and length most grows to 4 meters.Such as the deflector roll of Φ 125*500mm It is made using seamless steel pipe, the thickness of the roll body of the deflector roll cannot be below 15mm, and this thickening deflector roll is although meet super Requirement of the deflector roll long to roll body intensity, but increasing roll body thickness causes the wall thickness of deflector roll excessive, and deadweight increases, material, processing Cost all increases, and drives the power power consumption height of deflector roll, and the deadweight of deflector roll roll body has a strong impact on the linearity of deflector roll, circular runout Greatly, the balanced differences of whole seamless steel pipe deflector roll, eventually influences the rotation of deflector roll.Spreading roll is suitable in guide roller surface setting spiral To, reverse spread silk, spreading roll purpose is spread, and can not only be consumed energy height using the increase that the spreading roll of above-mentioned deflector roll is conducted oneself with dignity, Circular runout is big, and causes the tension force of cloth big, cloth can be damaged or elongated, and has a strong impact on spread, sub-wire effect, influences The quality of production.

Utility model content

The utility model is in view of the shortcomings of the prior art, there is provided a kind of lightweight and intensity is big, and circular runout is small Double-layer high strength deflector roll.

The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of double-layer high strength deflector roll, including roll body, Roll shaft and end cap, the roll body include outer tube and inner tube, by multiple along the roll body axle between the outer tube and said inner tube Connected to the annular solid of directional spreding, the roll shaft is connected with the inwall of said inner tube by flanged plate.

The beneficial effects of the utility model are：Roll body is coordinated using outer tube and inner tube, and interlayer sets the length of annular solid deflector roll Degree can reach more than 6 meters, and whole roll body bounce is reduced, and precision is improved, and static balance computing ballance correction is reduced, and not only reduces roll body Wall thickness, alleviate the weight of roll body, and ensure that the integrated support intensity of deflector roll, rotated more using the spreading roll of the deflector roll Gently, greatly reduce the tension force of cloth, improve spread effect.

On the basis of above-mentioned technical proposal, the utility model can also do following improvement.

Further, the end cap is sleeved on the roll shaft and is located at the two ends of the roll body.

Beneficial effect using above-mentioned further scheme is, for supporting roll shaft to protect the inside of roll body.

Further, the roll shaft is equipped with protection tube, the protection in the outside fixed cover of respective roller body end position The outer wall of sleeve pipe is connected with the end cap, flanged plate respectively.

Beneficial effect using above-mentioned further scheme is, in order to ensure the support strength of the roll shaft in roll body end position And compression strength, therefore needing to reduce roll shaft in solder joint herein, the design of protection tube can not only increase the roll shaft of roll body end Support strength, and the solder joint with end cap, flanged plate is transferred on protection tube the integrated support of further protection roll shaft Intensity, extends the service life of roll shaft.

Further, the protection tube is made using seamless steel pipe.

Beneficial effect using above-mentioned further scheme is, no-welding-seam bears that pressure is bigger, and support strength is big.

Specific embodiment

Principle of the present utility model and feature are described below in conjunction with example, example is served only for explaining this practicality It is new, it is not intended to limit scope of the present utility model.

As shown in figure 1, a kind of double-layer high strength deflector roll, including roll body, roll shaft 3 and end cap 6, the roll body includes outer tube 1 And inner tube 2, connected by multiple annular solids 4 along the roll body axial directional distribution between the outer tube 1 and said inner tube 2, The roll shaft 3 is connected with the inwall of said inner tube 2 by flanged plate 5.

The end cap 6 is sleeved on the roll shaft and is located at the two ends of the roll body.For supporting roll shaft to protect roll body It is internal.

The roll shaft 3 is equipped with protection tube 7 in the outside fixed cover of respective roller body end position, outside the protection tube Wall is connected with the end cap, flanged plate respectively.In order to ensure support strength and compression strength in the roll shaft of roll body end position, Therefore need to reduce roll shaft in solder joint herein, the design of protection tube can not only increase the support strength of the roll shaft of roll body end, And the solder joint with end cap, flanged plate is transferred on protection tube the further integrated support intensity of protection roll shaft, extend roller The service life of axle.

The protection tube 7 is made using seamless steel pipe.No-welding-seam bears that pressure is bigger, and support strength is big.

Multiple annular solids are now sleeved on the outside of inner tube vertically and are welded, then above-mentioned inner tube set dress is inserted into outer tube Inside, outside and the outer tube of the annular solid at two ends be welded and fixed, i.e., the annular solid at two ends as connector realize outer tube with it is interior Pipe is stably connected with, and the annular solid at middle part only plays the purpose of support outer tube, i.e., the annular solid at middle part is used as support member, support member Inner side fix on inner pipe, outside is brought into close contact with the inwall of outer tube, the inwall for supporting outer tube；It is set with roll shaft anti- Protecting pipe, on the outside of roll shaft, the outside welded flange plate of protection tube, roll sleeve dress is inserted into inner tube, near roll body end The flanged plate in portion is welded and fixed with inner tube, i.e., the flanged plate near roll body end is adpting flange plate for realizing roll shaft and inner tube Connection, it is pivot flange plate that flanged plate in the middle part of roll body is used to support the flanged plate in the middle part of inner tube, i.e. roll body, its inner side with Roll shaft is fixedly connected, and outside is brought into close contact the support strength for supporting inner tube to increase roll body with the inwall of inner tube, in roll body Load onto end cap, end cap and protecting tube, outer tube welding welding in two ends.

Roll body is coordinated using outer tube and inner tube, and interlayer sets annular solid, and roll body wall thickness weight saving more than 50% is overall strong Degree increases by more than 2 times, and the length of deflector roll can reach more than 6 meters, and whole roll body bounce is reduced, and precision is improved, and static balance is dynamic flat Weigh and reduce.

Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all in this practicality Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model Within the scope of shield.
