Abstract
The invention discloses a wall-surface temperature division control hot roller which comprises a roller tube and a hot oil passageway axially passing through the inside of the roller tube. The insideof the roller tube is also provided with a heat-insulating device. The invention has the simple structure and is easy for processing and manufacturing. The inside of the roller tube is provided with the heat-insulating device, so the hot oil inside the roller tube can not be directly contacted with all tube wall of the roller tube; at the same time, the heat-insulating device has a small thermal conductivity and a low heat exchange efficiency, so the hot oil can not effectively heat up the tube wall of the roller tube by the heat transfer of the heat-insulating device, therefore, the tube wallof the roller tube connected with the heat-insulating device can keep the temperature lower than the melting point of a design material.
Description
Technical field
The present invention relates to a kind of fixing device of imaging device, especially a kind of wall surface temperature zone control heat roller that is used for fixing device.
Background technology
In printing industry, printing decorative pattern, pattern much all are to be undertaken by the mode of hot-rolling heating at present, reserve a part of white space after the needs printing, during in order to other pattern of printing, existing hot-rolling just can subregion control satisfy requirement because of surface temperature; Have only size and shape, corresponding position, hot-rolling surface local temperature is reduced, make it to reach the fusing point of pattern material, could satisfy technological requirement, but but there is no the hot-rolling that the wall surface temperature subregion is controlled in the market by the required white space of reserving.The structure of the existing typical hot-rolling in market such as Fig. 1, Fig. 2 and shown in Figure 3 comprise roller pipe 50 and the interior porous petroleum pipeline 51 by roller pipe 50 centers.The two ends of interior porous petroleum pipeline 51 are stretched out roller pipe 50 and be provided with through hole 54 on the tube walls that is positioned at roller pipe 50.The inner chamber of interior porous petroleum pipeline 51 is a deep fat path 53.The outer wall of the both ends of the surface 52 of roller pipe 50 porous petroleum pipeline 51 in the center is extended and connected.During work, deep fat flows in deep fat path 53, and enters cavity between roller pipe 50 and the interior porous petroleum pipeline 51 by through hole 54, thereby the warm-up mill tube wall is to the temperature that is higher than the pattern material fusing point.
Summary of the invention
The object of the present invention is to provide a kind of wall surface temperature zone control heat roller, this hot-rolling can be controlled at the temperature of part surface below the fusing point of pattern material when work.
For achieving the above object, wall surface temperature zone control heat roller of the present invention comprises the roller pipe and axially by the deep fat path of roller pipe inside, also is provided with heat-proof device in the described roller pipe.
As a kind of improvement of the present invention, described heat-proof device is flute profile heat-insulation chamber plate or the heat insulating strip that is connected on the roller inside pipe wall, and described flute profile heat-insulation chamber plate and roller inside pipe wall surround heat-insulation chamber, and the two ends of heat-insulation chamber are sealed.
As another kind of improvement the of the present utility model, described heat-proof device is flute profile heat-insulation chamber plate or the heat insulating strip that is connected on the roller inside pipe wall, and described flute profile heat-insulation chamber plate and roller inside pipe wall surround heat-insulation chamber, and the two ends of heat-insulation chamber are provided with opening.
As a further improvement on the present invention, be provided with thermal insulation material in the described heat-insulation chamber or circulation has cooling fluid.
As another kind of improvement the of the present invention, be provided with thermal insulation material in the described heat-insulation chamber, thermal insulation material inside is provided with the fluid cooling tube.
As a further improvement on the present invention, the center of described roller pipe also axially is provided with interior pipe, and described deep fat path is the central column path that forms between outer wall of inner tube and roller inside pipe wall.
As another kind of improvement the of the present invention, described deep fat path is the interior porous petroleum pipeline that is arranged on the roller tube hub.
As a further improvement on the present invention, the roller tube wall that joins with described heat-proof device is a sheet steel.
The present invention is simple in structure, is easy to processing and fabricating.Be provided with heat-proof device in the roller pipe, the deep fat in the roller pipe just can't directly contact with whole tube walls of roller pipe; The coefficient of heat conductivity of heat-proof device is little simultaneously, and heat conduction efficiency is low, and deep fat can't come effective warm-up mill tube wall by the heat transmission of heat-proof device, and therefore the roller tube wall that links to each other with heat-proof device just can keep below the temperature of pattern material fusing point.
Be provided with thermal insulation material in the heat-insulation chamber or circulation has cooling fluid, can guarantee effectively that the roller tube wall that links to each other with heat-insulation chamber keeps lower temperature.
The roller tube wall that joins with heat-proof device is a sheet steel, has reduced the contact area between the heat part of this a part of roller tube wall and roller tube wall, thereby has reduced heat conduction between the two, and the roller tube wall that helps joining with heat-proof device keeps lower temperature.
