Description

technical field [0001] The invention relates to a heating system of a vulcanizing machine, in particular to a heating system of a vulcanizing machine heated by high-temperature oil. Background technique [0002] The vulcanizing machine is a thermosetting plastic pressing machine. The commonly used heating methods for the vulcanizing machine are: steam heating, electric heating tube or electric heating film heating or electromagnetic heating plate heating. Mold to maintain proper temperature during vulcanization. [0003] The principle of steam heating is: using the high-pressure steam produced by the boiler, the heat of the high-pressure steam is transferred to the mold to increase the temperature of the mold and vulcanize the rubber in the mold. The disadvantages of this method are that the equipment is huge, the waste of energy is large, the thermal efficiency is low, the ambient temperature around the vulcanizer is high, and the working environment is harsh. In addition,...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is: the electric heating tube is buried in the worktable, because the thermal efficiency of the electric heating tube is relatively low, the energy waste is large, and a large installed capacity is required; and it is easy to age and damage under high temperature, so frequent disassembly work is required To replace the electric heating tube, not only the maintenance cost is high, but also the workbench cannot be kept warm

The disadvantage of this heating method is that the wire of the electromagnetic heating plate is easily aged and damaged at high temperature, and the magnetic core in the electromagnetic heating plate is in point contact with the heat insulation plate at the bottom of the magnetic core. Under working pressure and high working temperature, the heat shield is easily broken due to excessive local pressure, the maintenance cost is high, and the maintenance needs to be shut down for a long time, which affects the production efficiency; the workbench and electromagnetic heating plate are often used Therefore, it is difficult to do heat preservation treatment, resulting in serious heat loss, large energy waste, high ambient temperature, and harsh working environment; in addition, when adjusting the frequent start and stop of the electromagnetic heating plate, it has a negative impact on the power grid. A certain impact requires that the function of the temperature controller must be very strong

[0007] Although this technical solution solves to a certain extent the problems of easy aging and damage and little impact on the load of the power grid that exist in the common vulcanizer heating device, it still has the problems of low heating efficiency, difficult temperature control, serious heat loss and complex structure.
