Description
Technical field
The utility model relates to the warm-up mill in a kind of film molding equipment, relates in particular to a kind of electric roller.
Background technology
The warm-up mill of conduction oil is current the most frequently used warm-up mill, its structure is relatively simple, cheap, therefore be used widely, and warm-up mill in existing film molding equipment is also to use heat-conducting oil heating conventionally, use the warm-up mill of conduction oil must use swivel joint and die heater, swivel joint is arranged on warm-up mill and connects with die heater, circulate and constantly heat conduction oil by die heater, again conduction oil is delivered to and in warm-up mill, makes its intensification, and conduction oil can produce expansion in the process heating, especially under the condition of high temperature, conduction oil is from die heater output, enter from swivel joint in the process of warm-up mill, the place that conduction oil is easily connected with warm-up mill from swivel joint leaks out, cause environmental pollution, affect enterprise employee health, even can cause fire, because die heater need consume a large amount of electric energy at circulation time, add the line loss of heating system, make energy waste serious, and existing Electromechanic heating roller, can avoid the problems referred to above, but Electromechanic heating roller is due to high content of technology, cost is also naturally high, not all factory can afford to use, be not easy to penetration and promotion.
Utility model content
For above deficiency, the utility model provides a kind of electric roller, and it is easy to use simple in structure, and production cost is low, and good heat conduction effect, is easy to penetration and promotion.
To achieve these goals, a kind of electric roller, it comprises outer roll body, interior roll body, end cap, rotating shaft and heating rod, outer roll body, interior roll body and rotating shaft are coaxial setting, and described interior roll body is arranged on outer roll body, the two ends of described interior roll body and outer roll body and end cap fixing seal, in interior roll body, form heat exchanging chamber, interlayer between interior roll body and outer roll body forms annular seal space, falling heat-transfer powder in described annular seal space, and described heating rod is interspersed in conductive powder.
For implementation structure optimization, its further measure is:
Described rotating shaft is provided with air admission hole, and this air admission hole connects and arranges along the length direction of rotating shaft; Described rotating shaft is provided with heat exchanging holes, with conducting air admission hole and heat exchanging chamber.
Described heating rod is along the length direction setting of rotating shaft and be uniformly distributed several.
Described heat exchanging holes is along the radial direction setting of rotating shaft.
Described heat exchanging holes can be made as several, to strengthen heat exchange efficiency.
The utility model adopts in the interlayer of the annular seal space forming between interior roll body and outer roll body and fills conductive powder, in rotating shaft, offer the technical scheme of the heat exchanging chamber conducting of air admission hole and heat exchanging holes and interior roll body, having overcome existing warm-up mill is conduction oil heat conduction, when being arranged on machine, warm-up mill must use die heater and swivel joint, when heat-conducting oil heating, easily produce and reveal at swivel joint place, cause environmental pollution, even cause the defect of security incident.
The beneficial effects of the utility model:
1) in the interlayer of the annular seal space forming between roll body and outer roll body in employing, fill conductive powder, avoid use conduction oil to conduct heat, therefore die heater and swivel joint can not use, and the conduction oil leakage problem at the swivel joint place of being caused by heat-conducting oil is also resolved, make to operate safer, do not pollute the environment.
2) owing to having adopted the higher and safer conductive powder of the better thermal efficiency of heat-conducting effect to carry out heat conduction, so now in order to make electric roller have better radiating effect, the heat exchanging chamber forming after roll body sealing in utilizing, and in rotating shaft, offer air admission hole and heat exchanging holes for conducting heat exchanging chamber, make electric roller produce heat exchange and regulating and controlling temperature by inject air in air admission hole, avoid electric roller heating-up temperature too high, keep electric roller all the time in suitable temperature, by injecting air to the temperature of carrying out heat exchange in heat exchanging chamber and adjust electric roller in air admission hole and heat exchanging holes, equivalent substitution die heater, further simplify the overall structure of film molding equipment, production and manufacturing cost are reduced.
3) adopt in rotating shaft several heat exchanging holes are set, strengthened the heat exchange efficiency of electric roller, shortened temperature fall time, energy-saving and cost-reducing.
