Metal can coating electromagnetic induction automatic drying heating device

Abstract

The invention discloses a metal can coating electromagnetic induction automatic drying heating device comprising a control cabinet and a heater. The control cabinet comprises a cabinet body, a power supply input terminal, a first aerial socket, a control panel, a main electromagnetic heating machine, a circuit breaker, an alternating current contactor, a switching power supply, an alarm signal board and a terminal bus. The heater comprises a housing, an electromagnetic induction coil, a micro-crystalline board and a second aerial socket. The control cabinet provides an alternating current to the heater through an electrical connection wire bundle. The metal can coating electromagnetic induction automatic drying heating device heats the metal can coating by means of electromagnetic induction heating, so as to dry the coating quickly. The metal can coating electromagnetic induction automatic drying heating device has the advantages of being safe in use, being environment-friendly, being energy-saving and being time-saving.

Description

technical field [0001] The invention relates to the technical field of metal cans, in particular to a metal can coating electromagnetic induction automatic drying and heating equipment. Background technique [0002] Metal packaging containers refer to thin-walled packaging containers made of sheet metal. Metal cans are a kind of metal packaging containers, which are widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrumentation packaging, industrial product packaging, arms packaging, etc. Among them, the largest number is used for food packaging. Among them, the three-piece can is the most mature and versatile method in the metal can manufacturing technology. During the manufacturing process, the weld seam of the can body needs to be treated with anti-oxidation. The most common method is to spray glue on the weld seam, and the glue needs to be dried quickly. Solidification. In the prior art, the drying and heating equipment genera...

Among them, the three-piece can is the most mature and versatile method in the metal can manufacturing technology. During the manufacturing process, the weld seam of the can body needs to be treated with anti-oxidation. The most common method is to spray glue on the weld seam, and the glue needs to be dried quickly. Solidification. In the prior art, the drying and heating equipment generally adopts the gas heating method, and the fire grate burner and the blast equipment are used to heat the tank body. The disadvantage is that the flame of the gas burner needs to be blown downward, and the hot air itself is The upward direction leads to uneven firepower, difficult control of heating temperature, and potential safety hazards. The working environment temperature of the canning production line is high, and the labor intensity of the workers is high. On the other hand, the combustion will emit a large amount of combustion exhaust gas and generate a large amount of carbon pollution. surroundings

[0003] There are also some drying and heating equipment that are heated by electric heating wires, which also fix the electric heating wires in a metal casing. Heating also relies on thermal radiation to dry and heat the coating of metal cans. The ambient temperature of the drying line is also very high, resulting in a great loss of energy, and the heating method of the heating wire is also the heating of the entire surface. The quality of the metal can coating has a certain influence
