The configuration of the steel cord conveyor belt vulcanizing machine needs to meet the requirements of high precision, high stability and high safety. The following is a detailed analysis from aspects such as mechanical structure, heating system, hydraulic system, control system and safety auxiliary devices:
First, mechanical structure configuration
The main frame of the vulcanizing machine: It needs to have high strength and rigidity to withstand the huge pressure during the vulcanization process. The frame design should take modularization into account to facilitate adjustment according to the width of the conveyor belt.
Vulcanizing plate: The vulcanizing plate is the core component of the vulcanizing machine, and its material should have good thermal conductivity and corrosion resistance. The size of the vulcanized plate should be customized according to the width of the conveyor belt and the requirements of the vulcanization process to ensure uniform temperature distribution during the vulcanization process.
Pressurization device: Usually, a hydraulic cylinder is used to provide the pressure required for vulcanization. The stroke and pressure of the hydraulic cylinder should be selected according to the vulcanization process requirements to ensure that the pressure is stable and adjustable during the vulcanization process.
Second, heating system configuration
Heating method: Electric heating or steam heating can be selected. The electric heating method has the advantages of precise temperature control and rapid temperature rise. Steam heating is suitable for large vulcanizing machines. It provides uniform heating but the temperature control is relatively complex.
Temperature sensors and controllers: High-precision temperature sensors are configured to monitor the temperature of the vulcanized plate in real time and feed back the signal to the temperature controller. The temperature controller should be equipped with PID regulation function to ensure that the vulcanization temperature remains stable within the set range.
Insulation layer: Insulation layers are set around the vulcanized plates to reduce heat loss and improve energy utilization efficiency.
Third, hydraulic system configuration
Hydraulic pump and motor: Select the appropriate hydraulic pump and motor to provide sufficient flow and pressure to meet the pressurization requirements during the vulcanization process.
Hydraulic valve assembly: Equipped with directional control valves, pressure control valves, flow control valves, etc., to achieve precise control of the hydraulic cylinder.
Hydraulic cylinders and seals: Hydraulic cylinders should have excellent sealing performance to prevent hydraulic oil leakage. Seals should be made of materials that are resistant to high temperatures and wear to ensure long-term stable operation.
Fourth, control system configuration
PLC controller: A programmable logic controller (PLC) is adopted as the core control unit to achieve the automatic control of the vulcanization process. The PLC should have powerful data processing capabilities and communication functions to facilitate data exchange with the host computer or other devices.
Human-machine Interface (HMI) : Equipped with a touch screen or operation panel as the human-machine interaction interface. Operators can set vulcanization parameters, monitor the vulcanization process and receive fault alarm information through the HMI.
Sensors and actuators: In addition to temperature sensors, pressure sensors, displacement sensors, etc. should also be configured to monitor various parameters during the vulcanization process in real time. The actuators include hydraulic valves, heaters, etc., and perform corresponding actions according to the instructions of the PLC.
Fifth, configuration of safety auxiliary devices
Safety shield: Install safety shields around the moving parts of the vulcanizing machine to prevent operators from coming into contact with dangerous areas.
Emergency stop button: An emergency stop button is set on the operation panel. In case of an emergency, the operator can immediately press the button to stop the operation of the vulcanizing machine.
Overload protection device: Overload protection devices are installed in the hydraulic system and electrical system to prevent equipment damage due to overload.
Temperature and pressure over-limit alarm: When the vulcanization temperature or pressure exceeds the set range, the system should automatically issue an alarm signal to remind the operator to handle it in time.
