Abstract
The utility model which provides a heating roll of a plastic encapsulating machine comprises a heating roll body which is formed by a heating part and a heat transferring part, and the two ends of the heating part are connected with a power supply wire, and the outside of the heating roll body is covered with a rubber layer, and the utility model is characterized in that the heating part is made by a conductive heating ceramic material, and the heat transferring part is made of a special-shaped aluminum pipe, and a through long empty cavity is arranged in the special-shaped aluminum pipe, and the heating part and the external covered insulation material are arranged in the empty cavity. The heating part is tightly contacted and connected with the heat transferring part by pressing in the manufacture process, therefore, the utility model which has the advantages of large contact surface and high heat transmission efficiency can save energy and prolong the service life of the plastic encapsulating machine.
Description
Technical field
The utility model relates to a kind of office and daily daily necessities, relates in particular to a kind of plastic packaging machine warm-up mill.
Background technology
Plastic packaging machine is widely used in office and daily life, at present, the plastic packaging machine electric heater unit mainly is to provide thermal source with the heating of metal part by heating wire heating power in insulating materials, realizes to the heating of plastics and to the plastic packaging of seal, and metalwork has round roll-type and flat two kinds.The subject matter of this electric heater unit is that heat transference efficiency is low, and heating wire blows easily in heating process and wear out, thereby maintenance cycle is short, and service life is short.
Summary of the invention
The purpose of this utility model is to provide a kind of novel plastic packaging machine warm-up mill, to improve heat transference efficiency, prolongs the service life of plastic packaging machine.
The purpose of this utility model is achieved in that a kind of plastic packaging machine warm-up mill, comprise the warm-up mill body of forming by heat generating member and heat transfer piece, the heat generating member both sides connect power line, the warm-up mill body is coating one deck rubber layer outward, be characterized in: described heat generating member is made of the conductive exothermal ceramic material, its outer one deck insulating materials that coats; Described heat transfer piece is made of special-shaped aluminum pipe, is provided with an elongated cavity in the special-shaped aluminum pipe, and described heat generating member and the outer insulating materials that coats thereof are installed in this cavity.
Above-mentioned a kind of plastic packaging machine warm-up mill, wherein, the two ends of the cavity in the described special-shaped aluminum pipe are aduncate " U " shape structure, respectively are provided with " U " shape groove together on its corresponding tube wall, should " U " shape groove with " U " shape structure of cavity between two relative " U " shape deformed areas of formation.
Because a kind of plastic packaging machine warm-up mill of the present utility model has adopted above technical scheme, adopt the conductive exothermal ceramic material as heat generating member, be provided with an elongated cavity in the heat transfer piece abnormity aluminum pipe, heat generating member and the outer insulating materials that coats thereof are installed in this cavity and closely contact with heat transfer piece.The heat transfer contact area is big, thereby has improved heat transference efficiency greatly, has saved the energy, has prolonged the service life of plastic packaging machine.
Description of drawings
Concrete structure of the present utility model is further provided by following examples and accompanying drawing thereof.
Fig. 1 is the structural representation of a kind of plastic packaging machine warm-up mill of the utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of plastic packaging machine warm-up mill of the utility model comprises special-shaped aluminum pipe 1, is located at the cavity 2 in the pipe, fills the conductive exothermal ceramic material 3 in cavity 2, be located at the copper power line plate 4 of electric ceramic material 3 two sides, and be enclosed within the outer rubber layer 5 of special-shaped aluminum pipe.Cavity 2 in the abnormity aluminum pipe 1 is aduncate " U " shape structure towards the two ends of tube wall; Respectively be provided with together " U " shape groove 6 on its corresponding tube wall, should " U " shape groove 6 with " U " shape structure of cavity 2 between two relative " U " shape deformed areas 7 of formation.This deformed area 7 is weak parts of special-shaped aluminum pipe, and when the vertical direction to two deformed areas applied external force, special-shaped aluminum pipe was radially deforming, and cavity can be compressed and attenuation.In the pipe of special-shaped aluminum pipe, be provided with at least one circular opening 8 vertically, to alleviate the weight of columniform special-shaped aluminum pipe 1.Outside conductive exothermal ceramic material 3 and the copper power line plate 4 that is attached thereto, coating insulating materials 9, with the security that guarantees to use.
A kind of plastic packaging machine warm-up mill of the utility model is in manufacturing process, behind the insulating materials of in cavity, putting into conductive exothermal ceramic material, power line plate and coating thereof, make the cavity attenuation by pressurization, make to reach tight contact between the chamber wall of cavity and the conductive exothermal ceramic material in the chamber, copper power line plate and the insulating materials and link to each other.Guaranteed that the power line plate contacts with the good of conductive exothermal ceramic material, reduced harmful resistance, increased the contact area of heat generating member and heat transfer piece simultaneously, improved heat transference efficiency.
After connecting power supply, 3 heatings of conductive exothermal ceramic material are passed to power line plate 4 with heat, pass to special-shaped aluminum pipe 1 and rubber layer 5 again, by the heating of rubber layer 5 realizations to plastic sheeting.
The utility model modern design, simple in structure, the heat transference efficiency height, long service life, very practical.
