The configuration of the vulcanizing machine for port and wharf conveyor belts should meet the following requirements:
Vulcanized plate configuration: The size of the vulcanized plate needs to be selected based on the width of the conveyor belt. Usually, the whole plate groove processing technology is adopted to ensure uniform heating. The temperature difference on the surface of the hot plate should be controlled within ±5℃, and the fine seam on the working surface under a pressure of 1MPa should not exceed 0.5mm. The hot plate should have the ability to heat up quickly. The time for it to rise from room temperature to vulcanization temperature should be less than 30 minutes, and the temperature adjustment range should cover 0-200℃.
Pressure system configuration: The pressure system should be equipped with an electric pump or a manual pump to provide uniform and stable pressure supply. The system needs to support uniform pressure regulation ranging from 0 to 1.8MPa and be equipped with a pressure divider to ensure the stability of pressure holding. The pressure bag should be made of pure rubber, with a one-time molding process to avoid leakage risks. The uniformity of pressure on the overall pressure plate needs to be guaranteed through structural design.
The configuration of the electrical control system: The electrical control box needs to integrate the intelligent temperature control function and adopt the PLC control system to achieve the automatic regulation of temperature, pressure and time. The system should have the ability to operate in both manual and automatic modes and support the pre-storage function of multiple sets of vulcanization parameters. The temperature control accuracy should reach ±5℃, and it should be equipped with safety devices such as disconnection alarm, overload protection, short circuit protection and leakage protection, and be provided with a waterproof, sturdy and lightweight protective cover.
Cooling system configuration: The cooling mode should support both forced cooling and natural cooling modes. The forced cooling time should be controlled within 15 minutes to reduce the temperature of the vulcanization working surface to below 60℃. The cooling system should be equipped with a quick connection device to ensure the circulation efficiency of the cooling medium, and at the same time, drainage pipe fittings should be set up to prevent water accumulation.
Structure and safety configuration: The main unit frame should be made of high-strength aluminum alloy or a frame-plate separation structure, and be equipped with a double-acting jack type vertical oil cylinder. The equipment needs to be equipped with position sensors to detect the stroke of each cylinder and achieve electronic multi-cylinder synchronous balance control. All electrical components must comply with explosion-proof standards. The power supply interface adopts a dedicated quick plug and pull method, and the waterway interface adopts a quick plug and pull copper interface. The equipment needs to be equipped with hoisting devices to facilitate transportation and installation.
Sealing and protective configuration: The sealing performance of each part must meet the pressure test requirements of 2.0MPa or above. The heating plate should be equipped with an external temperature detection hole and a protective sleeve. The electrical control box must meet the IP65 protection grade, and the cables should be integrated 7-core dedicated cables to ensure insulation, waterproofing and anti-interference performance. The surface of the equipment needs to be treated for rust prevention, and all components should be interchangeable with the existing equipment.
