Abstract
The utility model provides a kind of heating roller for being preheated to paper, including hollow form roll body, rolling assemblies, heating component and ceramic outer cylinder, and rolling assemblies include end cap and roll shaft, and heating component includes multiple heating tubes, thermal insulation layer and radiating layer；Multiple reinforced sheets are equidistantly fixed in the inside of hollow form roll body, are equidistantly equipped with multiple groove a along its circumferencial direction in the outside wall surface of hollow form roll body；It is equidistantly equipped on the inner wall of ceramic outer cylinder along its circumferencial direction and multiple is located at corresponding groove b with groove a, heating tube is located in the cavity being made of groove a and groove b, thermal insulation layer is between heating tube and groove a, and radiating layer is between heating tube and groove b；End cap is fixed on the both ends of hollow form roll body and ceramic outer cylinder by fastener.Heating effect can be improved in the utility model, more uniformly spreads heat, and can reduce loss of the high temperature heat to hollow form roll body, improves hollow form roll body intensity.
Description
Technical field
The utility model relates to a kind of heating roller, especially a kind of heating roller for being preheated to paper.
Background technique
In the heating roller for being currently used for preheating paper, generally there are following disadvantages:
1, heating effect is poor, and heat is unevenly distributed；
2, it is not provided with thermal insulation layer between heating tube and roll body, causes high temperature heat big to the loss of roll body, reduces roll body
Service life；
3, the intensity of hollow form roll body is lower.
Summary of the invention
Aiming at the shortcomings existing in the above problems, the utility model, which provides one kind, can be improved heating effect, make heat
Amount is more uniformly spread, and can reduce loss of the high temperature heat to hollow form roll body, improves the use of hollow form roll body intensity
In the heating roller preheated to paper.
To achieve the above object, the utility model provides a kind of heating roller for being preheated to paper, including hollow
Shape roll body (1), rolling assemblies, heating component and ceramic outer cylinder (4), the rolling assemblies include end cap (2) and are fixed on outside it
The roll shaft (3) of side, the heating component include multiple heating tubes (7), thermal insulation layer (5) and radiating layer (6)；
Multiple reinforced sheets (10) are equidistantly fixed in the inside of the hollow form roll body (1), in the hollow form roll body
(1) multiple groove a (8) are equidistantly equipped with along its circumferencial direction in outside wall surface；
Multiple and groove a (8) position is equidistantly equipped with along its circumferencial direction on the inner wall of the ceramic outer cylinder (4)
In corresponding groove b (9), the heating tube (7) is located at the cavity being made of the groove a (8) and the groove b (9)
In, for the thermal insulation layer (5) between the heating tube (7) and the groove a (8), the radiating layer (6) is located at the heating
It manages between (7) and the groove b (9)；
The end cap (2) is fixed on the two of the hollow form roll body (1) and the ceramic outer cylinder (4) by fastener (11)
End.
Compared with prior art, the utility model has the advantage that
Heating effect can be improved by radiating layer, and more uniformly spread heat；
Loss of the high temperature heat to hollow form roll body can be reduced by thermal insulation layer；
The intensity of hollow form roll body can be improved by multiple reinforced sheets.

Specific embodiment
As shown in Figures 1 and 2, the utility model provides a kind of heating roller for being preheated to paper, including hollow
Shape roll body 1, rolling assemblies, heating component and ceramic outer cylinder 4.
Multiple reinforced sheets 10, the edge in the outside wall surface of hollow form roll body 1 are equidistantly fixed in the inside of hollow form roll body 1
Its circumferencial direction is equidistantly equipped with multiple groove a8.
Rolling assemblies include end cap 2 and fixed roll shaft 3 on the outside.
On the inner wall of ceramic outer cylinder 4 along its circumferencial direction be equidistantly equipped with it is multiple be located at groove a8 it is corresponding recessed
Slot b9.
Heating component includes multiple heating tubes 7, thermal insulation layer 5 and radiating layer 6.Heating tube 7 is located at by groove a8 and groove b9
In the cavity constituted, thermal insulation layer 5 is between heating tube 7 and groove a8, and radiating layer 6 is between heating tube 7 and groove b9.
End cap 2 is fixed on the both ends of hollow form roll body 1 and ceramic outer cylinder 4 by fastener 11.
The above is only the preferred embodiment of the present invention, is merely illustrative for invention, rather than limits
Property.Those skilled in the art understand that in the spirit and scope defined by invention claim many changes can be carried out to it,
It modifies or even equivalent, but all will fall within the protection scope of the utility model.
