Description

Technical Field

[0001] The present invention belongs to the technical field of tire vulcanization heating, and particularly relates to an electromagnetic heating plate for a vulcanizer. Background Art

[0002] A tire is an annular elastic rubber product assembled on various vehicles or mechanical equipment, usually installed on a metal rim. With the continuous progress of science and technology, the manufacturing process of tires has become increasingly diversified and scientific. In order to improve the service life and overall quality of tires, during the production process, a vulcanizer is used to heat the tires to complete the vulcanization process. In the tire vulcanization process, traditional tire vulcanizers mainly rely on high-temperature saturated steam as the heat transfer medium, and this high-temperature saturated steam is usually obtained by heating water through burning fossil fuels such as coal in a boiler. This method has many disadvantages, such as high equipment investment costs, heavy maintenance costs, and serious pollution emissions. To address these problems, an electromagnetic heating plate for a vulcanizer is currently used for heating.

[0003] An electromagnetic induction heating plate for a tire vulcanizer with the authorization announcement number of CN 110103372 B adopts a closed high-frequency magnetic conduction strip structure, which enhances the magnetic field intensity of the eddy current plate, thus significantly improving the eddy current heating efficiency, reducing the large amount of combustion energy required for the heat transfer medium, and further reducing a series of problems such as high 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 the hot plate in the electromagnetic heating device of the traditional tire vulcanizer are of an integral structure. Although some are divided as a whole, the overall size is fixed. If tires with different diameters are processed, the entire electromagnetic heating plate needs to be replaced, and replacing the entire set of heating equipment will cause a long interruption time in the production line and is not convenient for disassembly and assembly, resulting in a decrease in production efficiency. Summary of the Invention

[0004] In view of this, the present invention provides an electromagnetic heating plate for a vulcanizer, which can realize the rapid disassembly and assembly of the heating component and the electromagnetic heating mechanism, can flexibly adjust the combined number of heating components to change the heating range of the electromagnetic heating plate, enables the device to quickly adapt to the vulcanization requirements of different specifications of tires through modular adjustable design, reduces the interruption time of the production line caused by replacing the entire set of heating equipment, improves the production efficiency, and at the same time improves the temperature accuracy of the vulcanization process through the multi-region independent temperature control function, improves the production efficiency, and reduces the manual adjustment cost.

[0005] To solve the above technical problems, the present invention provides an electromagnetic heating plate for a vulcanizer, which includes an electromagnetic heating mechanism. A number of heating components are movably arranged outside the electromagnetic heating mechanism in sequence from inside to outside. The heating component includes a number of annular aluminum plates movably arranged at the lower end outside the electromagnetic heating mechanism in sequence from inside to outside. At the upper end of each annular aluminum plate, there are sequentially arranged an annular partition plate, an annular mounting plate, an electromagnetic coil I, an upper annular sealing plate and an annular iron plate from bottom to top. Connection components are provided on both the electromagnetic heating mechanism and the number of annular aluminum plates, which realizes the quick disassembly and assembly of the heating component and the electromagnetic heating mechanism, and can flexibly adjust the combined number of heating components to change the heating range of the electromagnetic heating plate. Through the modular adjustable design, the device can quickly adapt to the vulcanization requirements of different specifications of tires, reduce the production line interruption time caused by replacing the whole set of heating equipment, and at the same time improve the temperature accuracy in the vulcanization process through the multi-region independent temperature control function, improve the production efficiency and reduce the manual adjustment cost.

[0006] The electromagnetic heating mechanism includes a magnetic isolation plate. At the upper end of the magnetic isolation plate, there are sequentially arranged a heat insulation plate, a coil plate, an electromagnetic coil II, a cover plate and a hot plate from bottom to top, which plays the role of electromagnetic heating.

[0007] The connection component includes a number of limiting grooves respectively arranged at the upper edge of the magnetic isolation plate and the upper ends of the number of annular aluminum plates. Limiting plates with the same number as the number of the limiting grooves are arranged on the inner arc surfaces at the upper ends of the magnetic isolation plate and the number of annular aluminum plates. The limiting plates are movably clamped with the adjacent limiting grooves on the same side, which plays the role of guiding and limiting.

[0008] The connection component further includes sliding grooves respectively arranged on one side of the inner cavity of the limiting grooves. Limiting columns are slidably connected in the sliding grooves. Limiting jacks are arranged on the limiting plates. The limiting columns are respectively movably inserted into the limiting jacks located in the same sliding groove, which plays the role of limiting and locking.

[0009] The connection component further includes springs respectively arranged between the limiting columns and their corresponding sliding grooves, which provides elastic acting force.

[0010] The connection component further includes annular rotating grooves respectively arranged at the lower edges of the magnetic isolation plate and the number of annular aluminum plates. The sliding grooves are respectively communicated with the vertically adjacent annular rotating grooves. Rotating rings are rotatably connected in the annular rotating grooves. The lower ends of the limiting columns are respectively fixedly connected with the vertically adjacent rotating rings, which can synchronously drive the corresponding limiting columns.

[0011] It further includes an operating member. The operating member includes a number of through openings respectively arranged on the outer arc surfaces of the magnetic isolation plate and the number of annular aluminum plates. A dial block is arranged at each through opening on the outer arc surface of the rotating ring, which is convenient for relevant staff to unlock.

[0012] The ends of the limiting columns are all inclined, which ensures the smooth movement between structures.

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

[0014] The beneficial effects of the above technical solutions of the present invention are as follows:

[0015] 1. When vulcanizing tires of different sizes, the operator selects the corresponding heating assembly composed of an annular aluminum plate, an annular partition plate, an annular mounting plate, an electromagnetic coil I, an upper annular sealing plate, and an annular iron plate, and the whole is sleeved on the electromagnetic heating mechanism and fixedly connected through the connecting assembly, thereby limiting and fixing the heating assembly. When it is necessary to further expand the heating range, select the corresponding heating assembly and repeat the above steps. When it is necessary to reduce the heating range, remove the corresponding heating assembly. The quick disassembly and assembly of the heating assembly and the electromagnetic heating mechanism are realized. The combined quantity of the heating assembly can be flexibly adjusted to change the heating range of the electromagnetic heating plate. After the adjustment is completed, the electromagnetic coil I operates synchronously to generate heat on the annular iron plate, which can be independently adjusted and kept flush with the upper end surface of the hot plate to ensure the uniformity of heating. Through the modular adjustable design, the device can quickly adapt to the vulcanization requirements of different specifications of tires, reduce the production line interruption time caused by replacing the whole set of heating equipment, and at the same time improve the temperature accuracy in the vulcanization process through the multi-region independent temperature control function, improve production efficiency, and reduce the manual adjustment cost.

[0016] 2. The operator selects the corresponding heating assembly composed of an annular aluminum plate, an annular partition plate, an annular mounting plate, an electromagnetic coil I, an upper annular sealing plate, and an annular iron plate, and the whole is sleeved on the electromagnetic heating mechanism. During this process, the limiting plate on the heating assembly will be movably clamped with the corresponding limiting groove on the electromagnetic heating mechanism. During the clamping process of the two, the limiting plate on the heating assembly will contact the inclined surface of the limiting column on the electromagnetic heating mechanism. As the two gradually fit together, the limiting column will be forced to overcome the elastic force of the spring and slide along the chute for avoidance. After the limiting plate and the limiting groove are completely clamped, the limiting column and its attached mechanism will immediately reset under the action of the spring return force and finally insert into the corresponding limiting jack, thereby limiting and fixing the heating assembly. When it is necessary to reduce the heating range, toggle the annular aluminum plate, and the rotation of the annular aluminum plate drives the corresponding limiting column to overcome the elastic force of the spring and slide along the chute, and finally separate from the corresponding limiting jack. At this time, the heating assembly can be removed, realizing the quick disassembly and assembly of the heating assembly and the electromagnetic heating mechanism.

[0017] 3. When it is necessary to reduce the heating range, just toggle the annular aluminum plate through the toggle block, and the rotation of the annular aluminum plate drives the corresponding limiting column to overcome the elastic force of the spring and slide along the chute, which is convenient for the relevant operators to operate.

Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention. Figures 1-6

[0026] Figures 1-6 This embodiment provides an electromagnetic heating plate for a vulcanizer, as Figures 1-6As shown in the figure, it includes an electromagnetic heating mechanism. Several heating components are movably arranged outside the electromagnetic heating mechanism from the inside to the outside in sequence. The heating components include several annular aluminum plates 100 movably arranged at the lower end outside the electromagnetic heating mechanism from the inside to the outside in sequence. At the upper end of each annular aluminum plate 100, there are an annular partition plate 101, an annular mounting plate 102, an electromagnetic coil 105, an upper annular sealing plate 103, and an annular iron plate 104 in sequence from bottom to top. Connecting components are provided on both the electromagnetic heating mechanism and several annular aluminum plates 100. The electromagnetic heating mechanism includes a magnetic isolation plate 200. At the upper end of the magnetic isolation plate 200, there are a heat insulation plate 201, a coil plate 202, an electromagnetic coil 205, a cover plate 203, and a heat plate 204 in sequence from bottom to top. The upper end surface of the heat plate 204 is flush with the upper end surfaces of several annular iron plates 104. Both the magnetic isolation plate 200 and the annular aluminum plates 100 are 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 fiberglass polyester ammonium material. Vertically, a set of the annular partition plate 101, the annular mounting plate 102, the electromagnetic coil 105, the upper annular sealing plate 103, and the annular iron plate 104 are fixedly connected by several locking bolts. Vertically, a set of the magnetic isolation plate 200, the heat insulation plate 201, the coil plate 202, the electromagnetic coil 205, the cover plate 203, and the heat plate 204 are fixedly connected by several fixing bolts.

[0027] First, the electromagnetic heating mechanism composed of the magnetic isolation plate 200, the heat insulation plate 201, the coil plate 202, the second electromagnetic coil 205, the cover plate 203, and the hot plate 204 is integrally and fixedly installed on the designated heating parts of the upper and lower molds of the vulcanizer, with the two hot plates 204 facing each other. During the heating operation, the second electromagnetic coil 205 is activated to generate an alternating magnetic field, causing the hot plate 204 to generate eddy currents and heat under the action of electromagnetic induction, thereby playing an electromagnetic heating role on the mold of the vulcanizer, achieving the effect of tire vulcanization, without consuming steam, and having a fast heating speed, greatly reducing heat loss. When vulcanizing tires of different sizes, the operator selects the corresponding heating component composed of the annular aluminum plate 100, the annular partition 101, the annular mounting plate 102, the first electromagnetic coil 105, the upper annular sealing plate 103, and the annular iron plate 104, and slews it on the electromagnetic heating mechanism and fixedly connects it through the connection component, thereby limiting and fixing the heating component. When it is necessary to continue to expand the heating range, select the corresponding heating component and repeat the above steps. When it is necessary to reduce the heating range, remove the corresponding heating component. This realizes the rapid disassembly and assembly of the heating component and the electromagnetic heating mechanism, and can flexibly adjust the combination number of the heating components to change the heating range of the electromagnetic heating plate. After the adjustment is completed, the first electromagnetic coil 105 operates synchronously to heat the annular iron plate 104, which can be independently adjusted and kept flush with the upper end face of the hot plate 204 to ensure heating uniformity. Through the modular adjustable design, the device can quickly adapt to the vulcanization requirements of different specifications of tires, reduce the production line interruption time caused by replacing the entire set of heating equipment, and at the same time improve the temperature accuracy of the vulcanization process through the multi-region independent temperature control function, improve production efficiency, and reduce the manual adjustment cost.

[0028] Such as Figures 1-6As shown, the connection component includes a plurality of limit grooves 300 respectively arranged at the upper edge of the magnetic isolation plate 200 and the plurality of annular aluminum plates 100, the limit grooves 300 are of rectangular structure, and the upper ends of the inner arc surfaces of the magnetic isolation plate 200 and the plurality of annular aluminum plates 100 are provided with limit plates 301 of the same number as the plurality of limit grooves 300, the limit plates 301 are of rectangular structure, and the limit plates 301 are movably connected with the limit grooves 300 adjacent to the same side, and the connection component also includes a slide groove 302 respectively arranged on one side of the inner cavity of the limit groove 300, the slide groove 302 is of arc structure, and the slide groove 302 is slidably connected with the limit column 303, and the limit column 303 is of arc structure. The structure is shaped, and limiting holes are provided on the limiting plates 301. The limiting posts 303 are movably connected with the limiting holes in the same slide groove 302. The connecting assembly also includes springs 304 respectively arranged between the limiting posts 303 and the slide grooves 302 in which they are located. The ends of the limiting posts 303 are inclined. The connecting assembly also includes annular rotating grooves respectively arranged at the edges of the lower ends of the magnetic isolation plate 200 and a plurality of annular aluminum plates 100. The slide grooves 302 are respectively connected with the vertically adjacent annular rotating grooves, and rotating rings 305 are rotatably connected in the annular rotating grooves. The lower ends of the limiting posts 303 are respectively fixedly connected with the vertically adjacent rotating rings 305.

[0029] The operator selects the corresponding heating component consisting of the annular aluminum plate 100, the annular partition plate 101, the annular mounting plate 102, the electromagnetic coil 105, the upper annular sealing plate 103 and the annular iron plate 104, and sets the heating component on the electromagnetic heating mechanism as a whole. During this process, the limit plate 301 on the heating component will be movably engaged with the corresponding limit groove 300 on the electromagnetic heating mechanism. During the engagement process of the two, the limit plate 301 on the heating component will contact the inclined surface of the limit column 303 on the electromagnetic heating mechanism. As the two gradually fit together, the limit column 303 is forced to overcome the elastic force of the spring 304 and slide along The groove 302 slides to avoid, and after the limit plate 301 and the limit groove 300 are fully engaged, the limit column 303 and its auxiliary mechanism are immediately reset under the action of the spring 304 rebound force, and finally inserted into the corresponding limit socket, so as to limit and fix the heating component. When it is necessary to narrow the heating range, the annular aluminum plate 100 is moved, and the annular aluminum plate 100 rotates to drive the corresponding limit column 303 to overcome the elastic force of the spring 304 and slide along the slide groove 302, and finally separate from the corresponding limit socket, then the heating component can be removed, and the heating component and the electromagnetic heating mechanism can be quickly disassembled and assembled.

[0030] like Figures 1-5 As shown, an operating member is also included, which includes a plurality of through openings 400 respectively arranged on the outer arc surfaces of the magnetic isolation plate 200 and the plurality of annular aluminum plates 100, and a shift block 401 is provided at each through opening 400 on the outer arc surface of the rotating ring 305.

[0031] When it is necessary to narrow the heating range, simply use the shifting block 401 to shift the annular aluminum plate 100. The rotation of the annular aluminum plate 100 drives the corresponding limit post 303 to slide along the chute 302 against the elastic force of the spring 304, facilitating the operation of relevant operators.

[0032] The working principle of an electromagnetic heating plate for a vulcanizer provided by the present invention is as follows: First, the electromagnetic heating mechanism composed of the magnetic isolation plate 200, the heat insulation plate 201, the coil plate 202, the electromagnetic coil two 205, the cover plate 203, and the hot plate 204 is integrally and fixedly installed on the designated heating parts of the upper and lower molds of the vulcanizer, with the two hot plates 204 facing each other. During the heating operation, the electromagnetic coil two 205 is activated to generate an alternating magnetic field, causing the hot plate 204 to generate eddy currents and heat under the action of electromagnetic induction, thereby playing an electromagnetic heating role on the mold of the vulcanizer, achieving the effect of tire vulcanization, without consuming steam, and having a fast heating speed, greatly reducing heat loss. When vulcanizing tires of different sizes, the operator selects the corresponding heating component composed of the annular aluminum plate 100, the annular partition plate 101, the annular mounting plate 102, the electromagnetic coil one 105, the upper annular sealing plate 103, and the annular iron plate 104 and slews it on the electromagnetic heating mechanism. During this process, the limiting plate 301 on the heating component will be movably clamped with the corresponding limiting groove 300 on the electromagnetic heating mechanism. During the clamping process of the two, the limiting plate 301 on the heating component 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 is forced to slide along the chute 302 against the elastic force of the spring 304 for avoidance. After the limiting plate 301 and the limiting groove 300 are completely clamped, the limiting post 303 and its affiliated mechanism immediately reset under the action of the restoring force of the spring 304 and finally insert into the corresponding limiting jack, thereby limiting and fixing the heating component. When it is necessary to further expand the heating range, select the corresponding heating component and repeat the above steps. When it is necessary to narrow the heating range, simply use the shifting block 401 to shift the annular aluminum plate 100. The rotation of the annular aluminum plate 100 drives the corresponding limiting post 303 to slide along the chute 302 against the elastic force of the spring 304 and finally separate from the corresponding limiting jack. At this time, the heating component can be removed, realizing the rapid disassembly and assembly of the heating component and the electromagnetic heating mechanism. The combined quantity of the heating components can be flexibly adjusted to change the heating range of the electromagnetic heating plate. After the adjustment is completed, the electromagnetic coil one 105 operates synchronously to heat the annular iron plate 104, which can be independently adjusted and kept flush with the upper end surface of the hot plate 204 to ensure heating uniformity. Through the modular adjustable design, the device can quickly adapt to the vulcanization requirements of different specifications of tires, reduce the production line interruption time caused by replacing the entire set of heating equipment, and at the same time improve the temperature accuracy during the vulcanization process through the multi-region independent temperature control function, improve production efficiency, and reduce the manual adjustment cost.

[0033] In addition, it should be noted that in the description of the present invention, unless otherwise clearly defined and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
