Abstract
The invention discloses an auxiliary heating device of a drum type vulcanizing machine. The auxiliary heating device of the drum type vulcanizing machine substitutes electromagnetic heating for traditional electric auxiliary heating equipment, and mainly comprises an electromagnetic coil, an arc-shaped plate, E-shaped magnetic cores, a copper block and a thermocouple. The arc-shaped plate is arranged at the rear side of a vulcanizing drum and is mounted on a machine base of the drum type vulcanizing machine through a short shaft; the radian of the arc-shaped plate is determined by vertical distance between a pressure belt at the upper and lower sides; a certain number of E-shaped magnetic cores are arranged tightly along the axis direction of the vulcanizing drum to form an integrated magnetic core of the whole arc-shaped plate; the electromagnetic coil is wound on a consequent pole of the integrated magnetic core uniformly; each point on the axis of the pressure belt has the same magnetic field intensity, so the heating uniformity of belt blanks is improved. The copper block with excellent heat conductivity and small volume is arranged close to the outer surface of the pressure belt, and the thermocouple is embedded into the copper block, so the surface temperature of the pressure belt can be measured indirectly by measuring the temperature of the copper block. Through the heating manner, heat is generated in the pressure belt and an external heat source is not introduced to heat the pressure belt, so the pressure belt is heated quickly, the heating efficiency is high and the vulcanization period is shortened.
