Description

[0002] In the electric heating vulcanization process, the control of the vulcanization medium temperature is very important. Currently, the heating control of vulcanizing machines is mostly achieved by directly connecting a PID controller or a board with its own OLED display and solid-state relays via wires. The temperature and other parameters are set for the PID controller through the PLC or the board's own OLED display. The PID controller controls the electric heating part by controlling the on and off of the solid-state relays. It also collects the temperature of the electric heating part through methods such as resistance temperature detectors (RTDs) and thermocouples. By comparing the feedback temperature with the set temperature, the corresponding on and off cycle is calculated, thereby controlling the electric heating temperature.
[0003] However, this wiring connection method requires relatively independent devices, and wiring is needed between devices, which occupies a large space. This results in a large footprint for the electrical cabinet in the vulcanizing machine and a large number of wiring cables.
[0004] Therefore, there is an urgent need for an integrated heating control system for vulcanizing machines to solve the problems of relatively independent components, the need for wiring between components, large space occupation, large electrical cabinet footprint, and numerous wiring cables in existing technologies.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0026] like Figure 1-2As shown in the figure, this application embodiment provides an integrated heating control system for a vulcanizing machine. The vulcanizing machine includes a heating module 5 for heating the vulcanizing medium. The control system includes: a circuit board 1; a control module 2; a low-voltage main control module 3, which is disposed on the circuit board 1 and whose input terminal is electrically connected to the output terminal of the control module 2; and a high-voltage controlled module 4, which is disposed on the circuit board 1 and whose input terminal is electrically connected to the output terminal of the low-voltage main control module 3 and whose output terminal is electrically connected to the heating module 5, for controlling the heating module 5 to heat the vulcanizing medium according to the output signal of the low-voltage main control module 3; wherein, the low-voltage main control module 3 is configured to control the high-voltage controlled module 4 according to the control signal output by the control module 2.
[0027] The low-voltage main control module 3 and the high-voltage controlled module 4 are integrated on circuit board 1, eliminating the need for separate PID controllers and solid-state relays. Therefore, there is no need to connect the low-voltage main control module 3 and the high-voltage controlled module 4 via wires. Simultaneously, the low-voltage main control module 3 is configured to control the high-voltage controlled module 4 based on the control signals output by control module 2. The high-voltage controlled module 4, in turn, controls the heating module 5 to heat the vulcanizing medium based on the output signals from the low-voltage main control module 3. This achieves heating control of the heating module 5 without the need for separate PID controllers and solid-state relays, saving space occupied by the heating control circuit within the vulcanizing machine cabinet. This further reduces the cabinet area and consequently the overall space occupied by the vulcanizing machine.
[0028] It should be noted that the electrical connection in this application can include physical connections achieved through current, signals, or electrical characteristics (such as wires, circuit board traces, solder joints, etc.), as well as non-physical connections achieved through electromagnetic waves for electrical signal interaction (such as Wi-Fi, Bluetooth, etc.). For example, the connection between the control module 2 and the circuit board 1 can be achieved through wires, circuit board traces, or solder joints, or through wireless connections such as Wi-Fi or Bluetooth; this application does not limit this.
[0029] Furthermore, the low-voltage main control module 3 may include a PID control chip, which is electrically connected to the control module 2 and the high-voltage controlled module 4 respectively; and / or, the high-voltage controlled module 4 includes a thyristor, which is electrically connected to the low-voltage main control module 3 and the heating module 5 respectively.
[0030] The PID control chip enables feedback control of heating-related parameters during vulcanization, such as temperature and pressure, thereby improving the heating accuracy of the vulcanizing machine. Furthermore, by placing the PID chip on circuit board 1 instead of directly using a PID controller, feedback control is achieved while avoiding the large footprint issues associated with independently connected components via wires. A thyristor is installed between the low-voltage main control module 3 and the heating module 5, allowing control of the high-power module (i.e., heating module 5) via the control modules 2 and 3, enabling the switching on / off of the high-power module (i.e., heating module 5) or other control conditions.
[0031] Meanwhile, the control module 2 preferably includes a PLC controller, which is simple to program, has a modular structure that is easy to maintain, and is small in size and low in cost, which can further improve the heating accuracy and overall size of the heating control system.
[0032] Furthermore, the output terminals of the PLC controller include switch signal output points and a first power ratio output point.
[0033] The PLC controller is equipped with switch signal output points and power ratio output points. Therefore, the PLC controller can control the switching of the low-voltage main control module 3, i.e., control the switching of the entire integrated heating control system of the vulcanizing machine, through the switch signal output points. Simultaneously, it can also control the heating power of the heating module 5 through the power ratio output points. The switch signals and power ratio signals output by the PLC controller can be manually input by technicians or adaptively adjusted according to other operating conditions of the vulcanizing machine, such as determining the optimal heating power based on the target heating temperature. This application does not impose any limitations on this.
[0034] It should be noted that, corresponding to the switch signal output point and the first power ratio output point, the low-voltage main control module 3 includes a switch signal input point and a first power ratio input point. When the user outputs the switch signal and the power ratio signal through the PLC controller, the switch signal enters the low-voltage main control module 3 through the switch signal output point and the switch signal input point, thereby controlling the opening and closing of the low-voltage main control module 3.
[0035] As another implementation, the low-voltage main control module 3 may also include a second power proportional input point.
[0036] That is, users can also directly input the power ratio to the low-voltage control module 3 through the second power ratio input point, thereby controlling the heating power of the heating module 5.
[0037] The power ratio signal input through the first power ratio input point and the power ratio signal input through the second power ratio input point have the same priority. That is, the heating module 5 will heat according to the currently input power ratio when the power ratio signal is input through either power ratio input point.
[0038] Meanwhile, the low-voltage control module 3 (e.g., a PID controller) can also be equipped with a display screen, which can display the current heating power or the current power ratio.
[0039] It should be noted that the PLC controller may also include a display screen. The display screen of the PLC and the display screen included in the low-voltage main control module 3 can be linked and set to simultaneously display the current heating power or the current power ratio or other parameter settings.
[0040] It should also be noted that the initial heating power of heating module 5 can be determined by the low-voltage control module (such as a PID controller) based on parameters such as actual heating needs and required heating time. After the user inputs the power ratio signal, heating module 5 will heat the module by multiplying the initial heating power by the power ratio. The power ratio is usually less than 100% and is used by technicians to control the heating power of the heating module.
[0041] As an optional implementation, it may also include: a temperature acquisition module 6, electrically connected to the low-voltage main control module 3, for acquiring the temperature of the vulcanizing medium; the low-voltage main control module 3 is further configured to control the heating module 5 to heat the vulcanizing medium through the high-voltage controlled module 4 according to the temperature of the vulcanizing medium.
[0042] By incorporating a temperature acquisition module 6 and connecting it to the low-voltage main control module 3, a temperature feedback path can be formed. When the low-voltage main control module 3 activates the heating module 5 to heat the vulcanizing medium via the high-voltage controlled module 4, the temperature acquisition module 6 can acquire the temperature of the vulcanizing medium in real time or periodically and send the temperature signal to the low-voltage main control module 3. The low-voltage main control module 3 can then use the target temperature and the temperature output by the temperature acquisition module 6 to control the on / off state of the heating module 5. This improves the intelligence level and temperature control accuracy of the heating control system.
[0043] It should be noted that the temperature acquisition module 6 is preferably a temperature sensor or an electronic thermometer, and the temperature sensor is preferably a resistance temperature detector (RTD) or a thermocouple. In other embodiments, the temperature acquisition module 6 may be one or other quantities, as long as it can accurately measure the temperature in the medium chamber and meet the requirements of continuous production.
[0044] Furthermore, in the electrically heated vulcanization process, the pressure inside the capsule is provided by the vulcanizing medium (usually nitrogen). The vulcanizing medium is heated externally or internally to reach the temperature required for the vulcanization process. The temperature of the vulcanizing medium also affects the pressure inside the capsule; the higher the temperature, the greater the pressure. Therefore, a pressure acquisition module, such as a pressure sensor, can also be provided. Its configuration can be the same as that of the temperature feedback module, and will not be elaborated further in this application.
[0045] As an optional implementation, the vulcanizing machine includes a medium chamber containing a vulcanizing medium; the heating module 5 and the temperature acquisition module 6 are both located in the medium chamber.
[0046] As an optional implementation method, such as Figure 2 As shown, it also includes a circuit breaker 7, an AC contactor 8, a fuse 9, and a heat sink 10; wherein, the circuit breaker 7, the AC contactor 8, and the fuse 9 are electrically connected in sequence and disposed on the circuit board 1, and the heat sink 10 and the fuse 9 are also electrically connected to the high-voltage controlled module 4 respectively.
[0047] At the same time, circuit breakers, AC contactors, and fuses can be electrically connected in sequence.
[0048] Heat sink 10 is used to dissipate heat from the controller and can be controlled by the high-voltage controlled module 4.
[0049] Preferably, circuit breakers, AC contactors, fuses, and heat sinks are mounted on the circuit board.
[0050] As an optional implementation, the low-voltage main control module 3 also includes: registers and a display screen.
[0051] The registers can be configured with RS-485 and Ethernet communication interfaces with the PLC controller, allowing the PLC to read the controller's internal registers.
[0052] The display screen may include an OLED display screen, which cycles through the information inside the controller. Manual parameter settings for the system can be made via buttons next to the display screen.
[0053] In addition, the low-voltage main control module 3 may also include multiple alarm output points, which can be configured to output alarms for various different situations, transmitting signals to the control module 2. The control module 2 then controls the alarm module to sound an alarm (e.g., warning lights, warning sounds, voice broadcasts, flashing display screens, etc.). The low-voltage main control module 3 may also include indicator lights, which can directly display warning information when there is an abnormality.
