This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] Please see Figures 1 to 5 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0052] This utility model provides a combined vulcanizing machine, specifically as follows: Figures 1 to 4 As shown, the combined vulcanizing machine includes an upper hot pressing module 10, a lower hot pressing module 20, fastening connectors 30, a high-pressure air pump, and a control unit 200. The upper hot pressing module 10 includes an upper beam 11, a pressure bag (not shown), an upper heat insulation plate 12, and an upper heating plate 13, arranged sequentially from top to bottom. Specifically, the pressure bag is formed by splicing a first sub-pressure bag and a second sub-pressure bag; the upper heat insulation plate 12 is formed by splicing a first sub-upper heat insulation plate 121 and a second sub-upper heat insulation plate 122; and the upper heating plate 13 is formed by splicing a first sub-upper heating plate 131 and a second sub-upper heating plate 132. The lower hot pressing module 20 includes a lower beam 20, a lower hot pressing module ... 1. The lower heat insulation plate 22 and the lower heating plate 23 are arranged sequentially from bottom to top. Specifically, the lower heat insulation plate 22 is formed by splicing the first sub-lower heat insulation plate 221 and the second sub-lower heat insulation plate 222, and the lower heating plate 23 is formed by splicing the first sub-lower heating plate 231 and the second sub-lower heating plate 232. The upper hot pressing module 10 and the lower hot pressing module 20 are connected by fastening connectors 30. The first sub-pressure bag and the second sub-pressure bag are both connected to the high-pressure air pump. The first sub-upper heating plate 131, the second sub-upper heating plate 132, the first sub-lower heating plate 231, the second sub-lower heating plate 231 and the high-pressure air pump are all connected to the control unit 200.

[0053] The beneficial effects of this utility model's combined vulcanizing machine are: During use, such as... Figure 1As shown, the conveyor belt 100 to be vulcanized is placed between the upper heating plate 13 and the lower heating plate 23. The upper heating plate 13 and the lower heating plate 23 are energized and heated by the control unit 200. Then, the control unit 200 controls the high-pressure air pump to start and fill the pressure bag with high-pressure gas to pressurize the vulcanizing machine, that is, to increase the thermal pressure between the upper hot pressing module 10 and the lower hot pressing module 20, thereby improving the quality of vulcanization of the conveyor belt 100. Because the pressure bag, upper heat insulation plate, upper heating plate, lower heat insulation plate, and lower heating plate of this utility model are all assembled from two parts, they can be assembled from the pressure bags, heat insulation plates, and heating plates of two existing vulcanizing machines with narrower widths. This allows for vulcanizing of wider conveyor belts. After the operation is completed, it can be disassembled into two small and medium-sized vulcanizing machines for vulcanizing small and medium-sized conveyor belts. Therefore, the combined vulcanizing machine of this utility model has strong applicability, high utilization rate, and ensures the quality of vulcanizing operations while reducing costs.

[0054] Specifically, such as Figure 1 As shown, during operation, the control unit 200 can synchronously control the power supply to the first upper heating plate 131, the second upper heating plate 132, the first lower heating plate 231, and the second lower heating plate 232, thereby achieving uniform heating of the upper heating plate 13 and the lower heating plate 23 and improving the quality of vulcanization. Similarly, during operation, the control unit 200 can control the filling amount of the high-pressure air pump, thereby controlling the pressure of the pressurized bladder, that is, ensuring the pressure consistency of the first and second pressurized bladders.

[0055] Furthermore, in order to accurately control and manage the heating temperature of the upper heating plate 13 and the lower heating plate 23, preferably, as follows: Figure 1As shown, in this embodiment, temperature sensors 40 are provided on the first upper heating plate 131, the second upper heating plate 132, the first lower heating plate 231, and the second lower heating plate 232 (only one temperature sensor is shown in the figure). During operation, all four temperature sensors are connected to the control unit 200. Through this design, during operation, the four temperature sensors transmit the temperatures corresponding to the first upper heating plate 131, the second upper heating plate 132, the first lower heating plate 231, and the second lower heating plate 232 to the control unit 200 in real time. This allows the control unit 200 to monitor the temperatures of the four heating plates in real time. When a temperature deviation occurs, the control unit 200 can adjust the temperature in real time to ensure consistency among the four heating plates, thereby further ensuring heating uniformity and improving vulcanization quality. Similarly, to accurately control and manage the pressure of the pressurized bag, preferably, as... Figure 1 As shown, pressure sensors 50 are installed on both the first and second sub-pressure bags, and both pressure sensors are connected to the control unit 200. Through this structural design, the two pressure sensors 50 transmit the pressure of the first and second sub-pressure bags to the control unit 200, allowing the control unit 200 to monitor the pressure of the first and second sub-pressure bags in real time. When a deviation occurs in the pressure of the first and second sub-pressure bags during operation, the control unit 200 can adjust the pressure in real time to ensure consistency between the pressure of the first and second sub-pressure bags, further improving the vulcanization quality.

[0056] Furthermore, during the pressure vulcanization of the conveyor belt, in order to ensure the consistency of the heat pressing on the conveyor belt, that is, to prevent one side of the conveyor belt from being pressed harder than the other, preferably, as follows: Figure 2 As shown, in this embodiment, two limiting blocks 60 are provided between the upper heating plate 13 and the lower heating plate 23. These two limiting blocks 60 are respectively disposed at the left and right ends of the lower heating plate 23, i.e., as shown... Figure 2 and Figure 3As shown, one limiting block 60 is located on the left side of the first lower heating plate 231, and the other limiting block 60 is located on the right side of the second lower heating plate 232. The limiting of these two blocks ensures the consistent downward pressure of the first and second sub-pressurized bags on the upper heating plate 13 (the first and second upper heating plates), thereby ensuring consistent pressure on the conveyor belt and thus ensuring the smoothness of the conveyor belt vulcanization. It is understood that in this embodiment, the height of the two limiting blocks 60 is slightly lower than the thickness of the conveyor belt 100.

[0057] Furthermore, after the vulcanization process is completed, in order to improve the cooling rate of the upper heating plate 13 and the lower heating plate 23, preferably, in this embodiment, the upper hot pressing module 10 also includes an upper water-cooled plate (not shown in the figure), which is disposed between the upper heating plate 13 and the upper heat insulation plate 12; similarly, the lower hot pressing module 20 includes a lower water-cooled plate, which is disposed between the lower heating plate 23 and the lower heat insulation plate 22; specifically, the upper and lower water-cooled plates have the same structure, that is, both the upper and lower water-cooled plates include a plate body, and a cold circulation pipe is provided inside the plate body. The cold circulation pipe includes an inlet and an outlet. During operation, external coolant enters the cold circulation pipe through the inlet for circulation and then flows out from the outlet.

[0058] Further, such as Figure 4 and Figure 5 As shown, in this embodiment, the upper beam 11, upper heat insulation plate 12, upper heating plate 13, lower heating plate 23, lower heat insulation plate 22, and lower beam 21 are all provided with slots; the fastening connector 30 includes a screw body 301, which is disposed in the slot, and the upper end of the screw body 301 protrudes from the upper beam 11, and the lower end of the screw body 301 protrudes from the lower beam 21. An upper nut 302 is threadedly connected to the upper end of the screw body 301, and an upper clamping block 303 is clamped between the upper nut 302 and the upper beam 11. A lower nut 304 is threadedly connected to the lower end of the screw body 301, and a lower clamping block 305 is clamped between the lower nut 304 and the lower beam 21. This structural design allows for the tightening of the upper hot-pressing module 10 and the lower hot-pressing module 20 by screwing on the upper nut 302 and the lower nut 304, thus achieving a secure connection between the two modules. The structure is simple and easy to assemble and disassemble.

[0059] Furthermore, in this embodiment, the lengths of the first sub-pressurization bag, the first sub-upper heat insulation plate 121, and the first sub-upper heating plate 131 are 1.2m; the lengths of the second sub-pressurization bag, the second sub-upper heat insulation plate 122, and the second sub-upper heating plate 132 are 1.8m.

[0060] Furthermore, in order to improve the uniformity of hot pressing, in this embodiment, the position where the first sub-pressurized bag and the second sub-pressurized bag are connected is staggered from the position where the first upper heat insulation plate 121 and the second upper heat insulation plate 122 are connected. That is, the position where the first sub-pressurized bag and the second sub-pressurized bag are spliced ​​together is staggered from the position where the first upper heat insulation plate 121 and the second upper heat insulation plate 122 are spliced ​​together. For example, when a 1.2m first sub-pressure bag and a 1.8m second sub-pressure bag are joined, the 1.2m first sub-pressure bag is located on the left side of the vulcanizing machine, and the 1.8m second sub-pressure bag is located on the right side. When the upper heat insulation plate 12 below the heating bag is positioned, the 1.2m first upper heat insulation plate 121 is located on the right side of the vulcanizing machine, and the 1.8m second upper heat insulation plate 122 is located on the left side. This ensures that the joining position of the first and second sub-pressure bags is perfectly staggered from the joining position of the first and second upper heat insulation plates 121 and 122, thus avoiding uneven pressurization caused by the two joining positions being vertically aligned. Similarly, the joining position of the first and second upper heat insulation plates 121 and 122 is also staggered from the joining position of the first and second upper heating plates 131 and 132 located below them. Specifically, the lower hot press module 20 is configured in the same way as the upper hot press module 10, so it will not be described again here.

[0061] Specifically, in this embodiment, the upper beam 11 and the lower beam 21 are made of aluminum alloy, which can reduce the weight of the vulcanizing machine while ensuring the strength requirements of the equipment.

[0062] In summary, the combined vulcanizing machine of this invention is suitable not only for vulcanizing wide conveyor belts but also for vulcanizing small and medium-sized conveyor belts. It boasts strong applicability and high utilization, ensuring vulcanizing quality while reducing costs. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0063] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
