Description
Technical field
The utility model relates to the die head of inflation film manufacturing machine in plastic products process equipment.
Background technology
Mode of heating at existing die head of film blowing machine, be utilize resistance heated plate produce mode that heat energy transmits by overheated conduction, heat by thermal energy transfer to die head, there is following problem in this mode of heating: 1, heats inhomogeneously, cause product became uneven, affect product quality.2, heat loss is large, affects working environment.During due to resistance heated, by heat conduction and thermal-radiating mode, to die head, heat, in its process of transmitting in heat, heat loss reaches 60%, causes energy waste.3, service life short, maintenance cost strengthens.
Summary of the invention
The utility model object is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of to the direct-fired a kind of device of die head of film blowing machine.The utility model is mainly by heat-insulation layer 1; Insulating barrier 2; Induction coil 3; Temperature control equipment 4; Sb variable-frequency power sources 5 is formed by connecting.The utility model can be realized by following frame mode: a kind of Novel film blowing machine die head electromagnetic heater, comprise heat-insulation layer 1 is wrapped on die head, insulating barrier 2 is wrapped on heat-insulation layer 1, and then the outside induction coil 3 that is wound around of insulating barrier 2, and induction coil 3 is connected with sb variable-frequency power sources 5.Temperature control equipment 4 is connected with sb variable-frequency power sources 5 after being arranged on die head.Principle of the present utility model is thereby that the electric high-frequency electrical by sb variable-frequency power sources output 20-40kHz of power frequency is realized and being heated at die head formation eddy current itself after induction coil.Insulating barrier, heat-insulation layer play heat insulation a, insulating effect, thereby temperature control control device reaches temperature control object according to the output of the temperature required control frequency converter of die head.
The utility model changes the mode that original Resistance Heating Film transmits by heat, and a kind of directly a kind of Novel film blowing machine die head of heating of die head that makes is provided.Take 100 degrees Celsius to 400 degrees Celsius be optimal way, and temperature rise speed is fast, outside does not produce heat, compared with prior art, the utility model produces the beneficial effect making new advances because of following characteristics.One, homogeneous heating, improves the quality of products.Its two, the thermal efficiency is high, improves working environment; Because die head is realized heating by eddy current, reduce original heat loss causing in heat transfer process, heat-insulation layer plays heat insulation effect, reduces heat loss, and its thermal efficiency is up to 96%, more energy-conservation more than 60% than original mode of heating.Its three, long service life.Induction coil itself does not produce heat, and the later stage is substantially without maintenance cost.
