Constant-temperature heating plate of vulcanizing machine

Abstract

The invention provides a constant-temperature heating plate of a vulcanizing machine. The constant-temperature heating plate comprises a heating plate body, a constant temperature layer, a heating layer and a circulating oil pump, wherein the heating layer is arranged below the constant-temperature layer and contacts the constant-temperature layer and comprises a first heat conduction oil pipe, asecond heat conduction oil pipe and a cavity structure, the first heat conduction oil pipe surrounds the outer side of the interior of the heating plate, the second heat conduction oil pipe is of an S-shaped wound structure and distributed in the middle of the constant temperature layer, and the cavity structure is equidistantly arranged on the second heat conduction oil pipe. By adopting the constant-temperature heating plate, the consistence of peripheral temperature and middle temperature of the heating plate can be effectively kept; moreover, the diameter of the first heat conduction oil pie is greater than the diameter of the second heat conduction oil pipe, so that more heat can be stored, and the heat dissipation speed can be reduced; and meanwhile, by adopting the cavity structure,the heat conduction oil having temperature difference in the pipe diameter can ensure the sufficient space to perform the sufficient heat exchange when in circulation, and the dynamic balance of thetemperature is realized, so that the uniformity of the temperature on the surface of the heating plate is ensured.

Description

technical field [0001] The invention relates to the technical field of rubber ring processing equipment, in particular to a constant temperature heating plate of a vulcanizer. Background technique [0002] The vulcanizing machine is the most commonly used processing equipment in the rubber industry. It is used to produce rubber seals. Rubber seals need to generate high temperature and high pressure conditions during the processing process. At present, the way to generate high temperature in the market is through electric heating tube heating and oil heating. or steam heating means to heat the heating plate; [0003] 1. Electric heating tube heating [0004] The electric heating tube is heated by inserting multiple heating tubes into the same heating plate. Due to the temperature difference between different parts of the electric heating tube, the heat will coalesce in the middle and upward after the heating plate is heated, which also leads to a larger temperature differenc...

AI Technical Summary

Problems solved by technology

Since the steam is easy to liquefy and the heat transfer effect is poor, the temperature difference between the steam inlet and the steam outlet is larger, and it is difficult to achieve the effect of constant temperature heating
