The adjustable tire vulcanization preheating device comprises an air preheating box and a heat exchange tube set; the air preheating box includes a shell, a pressure sensor and a temperature sensor; the heat exchange tube set is arranged in the shell, and is positioned on the edge of the shell; the air preheating box further includes an adjusting cylinder, and an adjusting mechanism capable of driving the adjusting cylinder to rotate; the adjusting cylinder is arranged at the outer periphery of the shell in a sleeving mode; thermal insulation grooves are formed in the outer side wall of the shell and the inner side wall of the adjusting cylinder correspondingly in the axial direction of the adjusting cylinder; thermal insulation layers produced by thermal insulation materials are embedded in the thermal insulation grooves; two sides of the thermal insulation grooves are heat conducting convex edges; the adjusting mechanism includes a controller and an actuation part; an input port of the controller is connected with a pressure sensor and a temperature sensor; an output port of the controller is connected with the actuation part; the actuation part can drive the adjusting cylinder and the shell to relatively rotate; and the adjusting structure can control the heat dissipating speed of the shell.

Description

technical field [0001] The invention relates to a tire production equipment, in particular to an adjustable tire vulcanization preheating device. Background technique [0002] The tire vulcanization process needs to consume a lot of heat, but a small part of the heat is actually used effectively, and most of it is dissipated in the ineffective pipeline circulation, and the heat dissipation is very large. In addition, most of the existing tire vulcanization processes do not have the step of preheating outside the machine. (Zhang Shukuan, Using the finite element method to study the influence of green tire preheating on the vulcanization temperature and curing degree field, Rubber Industry, Volume 5, 2003, 305-307), the green tire preheating has an obvious positive effect on tire vulcanization, and can Improve the uniformity of tire vulcanization and shorten the vulcanization time, but most tire manufacturers do not pay enough attention to this.

Problems solved by technology

Since the heat storage tank also has the function of storing water, the heat storage tank needs to have a sufficient volume, and filling a heat insulation layer in a larger heat storage tank will increase the cost of the heat storage tank; The volume of the hot water tank is small, so it is necessary to continuously draw out the water in the hot water storage tank to ensure the water storage function of the hot water storage tank, so part of the heat energy of the superheated water will not be able to be used

In addition, with the difference of the time that the superheated water stays in the hot water tank, if there is no heating device in the hot water tank, it is difficult to keep the water temperature in the hot water tank at a constant temperature. The temperature in the air preheating box is adjusted in the water tank, and the temperature in the air preheating box cannot be adjusted accurately

To sum up, the temperature in the air preheater cannot be precisely controlled through the hot water storage tank, and at the same time, the cost is high, and the thermal energy utilization rate of the superheated water is also low
