Description

Technical Field

[0001] This utility model belongs to the field of vulcanizing machine technology, specifically relating to a heating device for a flat vulcanizing machine. Background Technology

[0002] Vulcanizing machines are mainly used for vulcanizing flat rubber belts (such as conveyor belts and transmission belts, referred to as flat belts). They are hydraulic machines, and the main function of a flat vulcanizing machine is to provide the pressure and temperature required for vulcanization. The pressure is generated by the hydraulic system through hydraulic cylinders, and the temperature is provided by the heating medium (usually steam, heat transfer oil, etc., and superheated water is also used).

[0003] This flat vulcanizing machine requires a heating plate for heating during operation. Existing heating processes often use heating plates with heating tubes or heating wires inside. Heating is achieved through a medium inside the heating tubes or wires. However, due to the high heating efficiency of the heating tubes or wires, localized overheating can easily occur. The problem addressed by this device is how to solve the issue of localized overheating caused by the high heating efficiency of the heating tubes or wires. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a heating device for a flat vulcanizing machine, which solves the problem of high heating efficiency of heating tubes or heating wires, and the tendency for localized overheating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating device for a flat vulcanizing machine, comprising a housing, a baffle fixedly installed on the top of the housing, a heat spreader fixedly installed on the inner side of the baffle, a heating plate movably connected to the bottom of the heat spreader, a heating wire movably installed below the heating plate, an inlet pipe provided on the front side of the heat spreader, an outlet pipe provided on the other side of the heat spreader, a heat dissipation cylinder fixedly installed on the inner side of the housing, heat dissipation fins fixedly connected to the outside of the heat dissipation cylinder, a flexible hose fixedly connected to the top of the heat dissipation cylinder, and the heat dissipation cylinder connected to the inlet pipe and the outlet pipe through the flexible hose, and multiple inlet pipes and outlet pipes are provided, and the multiple inlet pipes and outlet pipes are arranged in a line inside the heat spreader, and a heating wire movably installed on the top of the heating plate.

[0006] Preferably, the heat spreader is provided with a limiting groove on its lower surface, and multiple limiting grooves are provided, and the heating plate is fitted into the baffle through the limiting groove.

[0007] Preferably, the limiting groove is provided with a power supply contact and an electromagnet, and multiple electromagnets are provided. The bottom end of the heating plate is provided with a connecting iron block, and the connecting iron block is arranged opposite to the electromagnet.

[0008] Preferably, there are six heating plates arranged in a linear array below the heat spreader. The heating plates and the baffle are provided with connecting contact points on opposite sides, and the connecting contact points are arranged opposite to the power supply contact points.

[0009] Preferably, limiting rods are movably installed on both sides of the limiting groove, and one end of the limiting rod is rotatably connected to a connecting lug.

[0010] Preferably, the heating wire is spiral-shaped, and multiple heating wires are provided.

[0011] Preferably, a base is fixedly installed on the bottom of the box, and four bases are provided on the bottom of the box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Heat is generated when the heating wire is energized, which heats the heating plate, allowing the heat to be evenly distributed to the vulcanizing machine. This eliminates hot spots and ensures that the vulcanizing mold or rubber compound is heated evenly, improving product quality. Heat is evenly distributed by the heat transfer oil, preventing localized overheating and ensuring uniform heating of the flat vulcanizing machine. The heat transfer oil can circulate through the inlet and outlet pipes, further improving temperature uniformity. The heat dissipation cylinder and fins reduce the frequency of heating wire start-stop and extend the service life of parts. Attached Figure Description
