Description

Technical Field

[0001] This utility model belongs to the field of tire vulcanization heating technology, specifically relating to an electromagnetic heating plate for a vulcanizing machine. Background Technology

[0002] Tires are circular, elastic rubber products fitted onto various vehicles or mechanical equipment, typically mounted on metal rims. With the continuous advancement of science and technology, tire manufacturing processes have become increasingly diversified and scientific. To improve tire lifespan and overall quality, a vulcanizing machine is used to heat the tire during production to complete the vulcanization process. In the traditional tire vulcanization process, the vulcanizing machine mainly relies on high-temperature saturated steam as the heat transfer medium. This high-temperature saturated steam is usually obtained by heating water by burning fossil fuels such as coal in a boiler. This method has many drawbacks, such as high equipment investment costs, heavy maintenance costs, and serious pollution emissions. To address these issues, an electromagnetic heating plate is currently used in the vulcanizing machine for heating.

[0003] The electromagnetic induction heating plate for a tire vulcanizing machine, authorized by announcement number CN 110103372 B, adopts a closed high-frequency magnetic strip structure, which enhances the magnetic field strength of the eddy current plate, thereby significantly improving the eddy current heating efficiency and reducing the large amount of combustion energy required for the heat transfer medium. This reduces a series of problems such as large equipment investment, high maintenance costs, and serious pollution emissions. Although it can achieve the effect of electromagnetic heating, in actual operation, the electromagnetic plate and heating plate in the electromagnetic heating device of the traditional tire vulcanizing machine are an integral structure. Although some are divided into parts, the overall size is fixed. If tires of different diameters are to be processed, the entire electromagnetic heating plate needs to be replaced. Replacing the entire heating equipment will cause long production line interruption time, and disassembly and assembly are inconvenient, resulting in a decrease in production efficiency. Utility Model Content

[0004] In view of this, the present invention provides an electromagnetic heating plate for a vulcanizing machine, which can achieve quick assembly and disassembly of the heating components and the electromagnetic heating mechanism, and can flexibly adjust the combination of the heating components to change the heating range of the electromagnetic heating plate. Through modular and adjustable design, the device can quickly adapt to the vulcanizing requirements of different tire specifications, reduce production line downtime caused by replacing the entire heating equipment, improve production efficiency, and at the same time improve the temperature accuracy of the vulcanizing process through multi-zone independent temperature control function, improve production efficiency, and reduce manual adjustment costs.

[0005] To address the aforementioned technical problems, this utility model provides an electromagnetic heating plate for a vulcanizing machine, comprising an electromagnetic heating mechanism. Several heating components are movably arranged sequentially from the inside out on the exterior of the electromagnetic heating mechanism. Each heating component includes several annular aluminum plates movably arranged sequentially from the inside out at the lower end of the exterior of the electromagnetic heating mechanism. Each annular aluminum plate has, from bottom to top, an annular partition, an annular mounting plate, an electromagnetic coil, an upper annular sealing plate, and an annular iron plate. Connecting components are provided on both the electromagnetic heating mechanism and the annular aluminum plates, enabling rapid assembly and disassembly of the heating components and the electromagnetic heating mechanism. The number of heating components can be flexibly adjusted to change the heating range of the electromagnetic heating plate. The modular and adjustable design allows the device to quickly adapt to the vulcanizing requirements of tires of different specifications, reducing production line downtime caused by replacing the entire heating equipment. Simultaneously, the multi-zone independent temperature control function improves the temperature accuracy of the vulcanizing process, increases production efficiency, and reduces manual adjustment costs.

[0006] The electromagnetic heating mechanism includes a magnetic shielding plate. From bottom to top, the upper end of the magnetic shielding plate is provided with a heat insulation plate, a coil plate, an electromagnetic coil, a cover plate, and a heating plate, which serves the purpose of electromagnetic heating.

[0007] The connecting assembly includes multiple limiting grooves respectively set at the upper edge of the magnetic shielding plate and several annular aluminum plates. The upper edge of the inner arc surface of the magnetic shielding plate and several annular aluminum plates is provided with a limiting plate with the same number as the multiple limiting grooves. The limiting plate is movably engaged with the adjacent limiting groove on the same side, which plays a guiding and limiting role.

[0008] The connecting assembly also includes sliding grooves respectively set on one side of the inner cavity of the limiting groove. Each sliding groove is slidably connected to a limiting post. Each limiting plate is provided with a limiting insertion hole. The limiting posts are movably inserted into the limiting insertion holes located in the same sliding groove, which serves as a limiting and locking function.

[0009] The connecting assembly also includes springs respectively disposed between the limiting post and the slide groove, which provide elastic force.

[0010] The connecting assembly also includes annular rotating grooves respectively set at the lower edges of the magnetic shielding plate and several annular aluminum plates. The vertically adjacent annular rotating grooves are connected to each other. Rotating rings are rotatably connected in each annular rotating groove. The lower ends of the limiting posts are fixedly connected to the vertically adjacent rotating rings, so that the corresponding limiting posts can be driven synchronously.

[0011] It also includes an operating component, which includes multiple through openings respectively set on the outer arc surface of the magnetic shielding plate and several annular aluminum plates. A lever is provided at each through opening on the outer arc surface of the rotating ring, which facilitates unlocking by relevant personnel.

[0012] The ends of the limiting columns are all inclined to ensure smooth movement between structures.

[0013] The upper surface of the hot plate is flush with the upper surface of several annular iron plates, thus ensuring uniform heating.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] 1. When vulcanizing tires of different sizes, the operator selects the corresponding heating assembly, consisting of an annular aluminum plate, annular partition, annular mounting plate, electromagnetic coil I, upper annular sealing plate, and annular iron plate, and mounts it onto the electromagnetic heating mechanism. This assembly is then fixed in place by connecting components, thus limiting and fixing the heating component. To expand the heating range, the corresponding heating assembly is selected and the above steps are repeated. To reduce the heating range, the corresponding heating assembly is removed, enabling quick assembly and disassembly of the heating assembly and electromagnetic heating mechanism. The number of heating components can be flexibly adjusted to change the heating range of the electromagnetic heating plate. After adjustment, the electromagnetic coil I operates synchronously to heat the annular iron plate, which can be independently adjusted and kept flush with the upper surface of the heating plate to ensure uniform heating. The modular and adjustable design allows the device to quickly adapt to the vulcanization needs of tires of different specifications, reducing production line downtime caused by replacing the entire heating equipment. Simultaneously, the multi-zone independent temperature control function improves the temperature accuracy of the vulcanization process, increases production efficiency, and reduces manual adjustment costs.

[0016] 2. The operator selects the heating assembly, consisting of the corresponding annular aluminum plate, annular partition, annular mounting plate, electromagnetic coil, upper annular sealing plate, and annular iron plate, and fits it onto the electromagnetic heating mechanism. During this process, the limiting plate on the heating assembly will engage with the corresponding limiting groove on the electromagnetic heating mechanism. During this engagement, the limiting plate on the heating assembly will contact the inclined surface of the limiting post on the electromagnetic heating mechanism. As the two gradually fit together, the limiting post will overcome the spring force and slide along the slide groove to avoid the spring. After the limiting plate and the limiting groove are fully engaged, the limiting post and its auxiliary mechanism will immediately reset under the action of the spring force and finally insert into the corresponding limiting hole, thereby limiting and fixing the heating assembly. When it is necessary to reduce the heating range, the annular aluminum plate is moved. The annular aluminum plate rotates and drives the corresponding limiting post to overcome the spring force and slide along the slide groove, eventually separating from the corresponding limiting hole. At this time, the heating assembly can be removed, realizing the quick assembly and disassembly of the heating assembly and the electromagnetic heating mechanism.

[0017] 3. When it is necessary to reduce the heating range, simply move the annular aluminum plate with the toggle block. The rotation of the annular aluminum plate will cause the corresponding limit post to overcome the elastic force of the spring and slide along the slide groove, making it convenient for relevant operators to operate.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] This embodiment provides an electromagnetic heating plate for a vulcanizing machine, such as... Figure 1-6As shown: The system includes an electromagnetic heating mechanism. Several heating components are movably arranged sequentially from the inside out on the outside of the electromagnetic heating mechanism. Each heating component includes several annular aluminum plates 100 movably arranged sequentially from the inside out at the lower end of the electromagnetic heating mechanism. Each annular aluminum plate 100 has, from bottom to top, an annular partition 101, an annular mounting plate 102, an electromagnetic coil 105, an upper annular sealing plate 103, and an annular iron plate 104. Connecting components are provided on the electromagnetic heating mechanism and the several annular aluminum plates 100. The electromagnetic heating mechanism includes a magnetic shielding plate 200. The upper end of the magnetic shielding plate 200 has, from bottom to top, a heat insulation plate 201, a coil plate 202, an electromagnetic coil 205, a cover plate 203, and... The upper surface of the hot plate 204 is flush with the upper surface of several annular iron plates 104. The magnetic shielding plate 200 and the annular aluminum plate 100 are both made of aluminum, which can effectively resist magnetism. The annular mounting plate 102, the upper annular sealing plate 103, the coil plate 202 and the cover plate 203 are all made of high-temperature resistant and insulating glass fiber polyurethane. Vertically, a set of annular partition plates 101, annular mounting plates 102, electromagnetic coil one 105, upper annular sealing plate 103 and annular iron plates 104 are fixedly connected by several locking bolts. Vertically, a set of magnetic shielding plates 200, heat insulation plates 201, coil plates 202, electromagnetic coil two 205, cover plate 203 and hot plate 204 are fixedly connected by several fixing bolts.

[0027] First, the electromagnetic heating mechanism, consisting of the magnetic shielding plate 200, heat insulation plate 201, coil plate 202, electromagnetic coil 205, cover plate 203, and hot plate 204, is fixedly installed onto the designated heating positions of the upper and lower molds of the vulcanizing machine, with the two sets of hot plates 204 facing each other. During the heating operation, the electromagnetic coil 205 is activated to generate an alternating magnetic field, causing the hot plate 204 to generate eddy currents and heat up under electromagnetic induction, thereby electromagnetically heating the molds of the vulcanizing machine and achieving the effect of tire vulcanization. This process eliminates the need for steam consumption, provides rapid heating, and significantly reduces heat loss. When different sizes of tires need to be vulcanized, the operator selects the corresponding heating assembly, consisting of the annular aluminum plate 100, annular partition plate 101, annular mounting plate 102, electromagnetic coil 105, upper annular sealing plate 103, and annular iron plate 104, and fits it onto the electromagnetic heating mechanism. The heating element is fixedly connected to the upper part of the device via a connecting component, thereby limiting and fixing the heating element. When it is necessary to further expand the heating range, the corresponding heating element is selected and the above steps are repeated. When it is necessary to reduce the heating range, the corresponding heating element is removed, realizing the quick assembly and disassembly of the heating element and the electromagnetic heating mechanism. The number of heating elements can be flexibly adjusted to change the heating range of the electromagnetic heating plate. After adjustment, the electromagnetic coil 105 operates synchronously to heat the annular iron plate 104. It can be independently adjusted and kept flush with the upper surface of the hot plate 204 to ensure uniform heating. The modular and adjustable design allows the device to quickly adapt to the vulcanization requirements of different tire specifications, reducing the production line interruption time caused by replacing the entire heating equipment. At the same time, the multi-zone independent temperature control function improves the temperature accuracy of the vulcanization process, increases production efficiency, and reduces manual adjustment costs.

[0028] like Figure 1-6As shown, the connecting assembly includes multiple limiting grooves 300 respectively disposed at the upper edges of the magnetic shielding plate 200 and several annular aluminum plates 100. The limiting grooves 300 are rectangular in structure. The upper ends of the inner arc surfaces of the magnetic shielding plate 200 and several annular aluminum plates 100 are provided with limiting plates 301 in the same number as the multiple limiting grooves 300. The limiting plates 301 are rectangular in structure and are movably engaged with the adjacent limiting grooves 300 on the same side. The connecting assembly also includes sliding grooves 302 respectively disposed on one side of the inner cavity of the limiting grooves 300. The sliding grooves 302 are arc-shaped, and each sliding groove 302 is slidably connected with a limiting post 303. The limiting post 303 is arc-shaped. The structure includes a limiting plate 301 with limiting holes, and limiting posts 303 are movably inserted into the limiting holes located in the same slide groove 302. The connecting assembly also includes springs 304 respectively disposed between the limiting posts 303 and their respective slide grooves 302. The ends of the limiting posts 303 are all inclined. The connecting assembly also includes annular rotating grooves respectively disposed at the lower edges of the magnetic shielding plate 200 and several annular aluminum plates 100. The vertically adjacent annular rotating grooves of the slide groove 302 are connected. Rotating rings 305 are rotatably connected in each annular rotating groove. The lower ends of the limiting posts 303 are fixedly connected to the vertically adjacent rotating rings 305.

[0029] The operator selects the heating assembly consisting of the corresponding annular aluminum plate 100, annular partition 101, annular mounting plate 102, electromagnetic coil 105, upper annular sealing plate 103, and annular iron plate 104, and fits it onto the electromagnetic heating mechanism. During this process, the limiting plate 301 on the heating assembly will engage with the corresponding limiting groove 300 on the electromagnetic heating mechanism. During this engagement, the limiting plate 301 on the heating assembly will contact the inclined surface of the limiting post 303 on the electromagnetic heating mechanism. As the two gradually fit together, the limiting post 303 will overcome the elastic force of the spring 304 and slide along the edge. The groove 302 slides to avoid collision. After the limiting plate 301 and the limiting groove 300 are fully engaged, the limiting post 303 and its auxiliary mechanism immediately reset under the action of the spring 304 and finally insert into the corresponding limiting hole, thereby limiting and fixing the heating component. When it is necessary to reduce the heating range, the annular aluminum plate 100 is moved. The annular aluminum plate 100 rotates and drives the corresponding limiting post 303 to slide along the groove 302 against the elastic force of the spring 304 and finally separate from the corresponding limiting hole. At this time, the heating component can be removed, realizing the quick assembly and disassembly of the heating component and the electromagnetic heating mechanism.

[0030] like Figure 1-5 As shown, it also includes an operating component, which includes multiple through openings 400 respectively disposed on the outer arc surfaces of the magnetic shielding plate 200 and several annular aluminum plates 100. A lever 401 is provided on the outer arc surface of the rotating ring 305 at each through opening 400.

[0031] When it is necessary to reduce the heating range, simply move the annular aluminum plate 100 by using the toggle block 401. The rotation of the annular aluminum plate 100 will cause the corresponding limit post 303 to slide along the slide groove 302 against the elastic force of the spring 304, making it convenient for relevant operators to perform the operation.

[0032] The working principle of the electromagnetic heating plate for a vulcanizing machine provided by this utility model is as follows: First, the electromagnetic heating mechanism, consisting of a magnetic shielding plate 200, a heat insulation plate 201, a coil plate 202, an electromagnetic coil 205, a cover plate 203, and a hot plate 204, is fixedly installed on the designated heating parts of the upper and lower molds of the vulcanizing machine, so that the two sets of hot plates 204 are opposite each other. During the heating operation, the electromagnetic coil 205 is activated to generate an alternating magnetic field, causing the hot plate 204 to generate eddy currents and heat up under the action of electromagnetic induction, thereby electromagnetically heating the mold of the vulcanizing machine and achieving the effect of tire vulcanization. It does not require steam consumption, and the heating speed is fast, greatly reducing the consumption of steam. With reduced heat loss, when vulcanizing tires of different sizes, the operator selects the appropriate heating assembly, consisting of an annular aluminum plate 100, an annular partition 101, an annular mounting plate 102, an electromagnetic coil 105, an upper annular sealing plate 103, and an annular iron plate 104, and fits it onto the electromagnetic heating mechanism. During this process, the limiting plate 301 on the heating assembly engages with the corresponding limiting groove 300 on the electromagnetic heating mechanism. During this engagement, the limiting plate 301 on the heating assembly contacts the inclined surface of the limiting post 303 on the electromagnetic heating mechanism. As the two gradually fit together, the limiting post 303 overcomes the force of the spring 304. The spring force slides along the slide groove 302 to avoid the resistance. After the limiting plate 301 and the limiting groove 300 are fully engaged, the limiting post 303 and its auxiliary mechanism immediately reset under the action of the spring force of the spring 304 and finally insert into the corresponding limiting hole, thereby limiting and fixing the heating component. When it is necessary to continue to expand the heating range, the corresponding heating component is selected and the above steps are repeated. When it is necessary to reduce the heating range, it is only necessary to move the annular aluminum plate 100 by the lever 401. The rotation of the annular aluminum plate 100 drives the corresponding limiting post 303 to overcome the spring force of the spring 304 and slide along the slide groove 302, and finally separate from the corresponding limiting hole. The heating components can be removed immediately, enabling quick assembly and disassembly of the heating components and electromagnetic heating mechanism. The number of heating components can be flexibly adjusted to change the heating range of the electromagnetic heating plate. After adjustment, the electromagnetic coil 105 operates synchronously to heat the annular iron plate 104. It can be independently adjusted and kept flush with the upper surface of the hot plate 204 to ensure uniform heating. The modular and adjustable design allows the device to quickly adapt to the vulcanization requirements of tires of different specifications, reducing production line downtime caused by replacing the entire heating equipment. At the same time, the multi-zone independent temperature control function improves the temperature accuracy of the vulcanization process, increases production efficiency, and reduces manual adjustment costs.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
