Description

Technical Field

[0001] This application belongs to the field of tire manufacturing, specifically relates to tire vulcanization equipment, and particularly relates to a medium stirring device in such equipment.

Background Art

[0002] The vulcanization process is commonly used in industrial production and can be used to improve the overall hardness of materials. In the field of tire manufacturing, it is particularly necessary to perform vulcanization treatment on the outer tire, thereby curing the plastic rubber with viscoelasticity to form a usable tire product.

[0003] In the conventional tire vulcanization process, vulcanization is usually carried out by means of combining saturated steam and nitrogen gas. Specifically, the above vulcanization process is as follows. That is, first, an unvulcanized green tire is placed between a sealed vulcanization capsule and a vulcanization mold. Then, saturated steam capable of supplying heat required for vulcanization is put into the vulcanization capsule. Next, high-pressure nitrogen gas is introduced to supply the pressure required for vulcanization. Due to the heat of the saturated steam and the pressure of the high-pressure nitrogen gas, the vulcanization capsule expands to press and heat the green tire, thereby performing shaping and vulcanization operations on the green tire.

[0004] The steam entering the vulcanization capsule condenses, and the condensed condensed water accumulates at the lower part of the vulcanization capsule, resulting in a relatively large temperature difference between the upper and lower parts of the vulcanization capsule, which further affects the vulcanization effect of the tire. This is one of the problems that occur during the operation of the steam vulcanizer. In addition, to supply steam to the vulcanization capsule, it is necessary to arrange a steam pipeline, and this steam pipeline occupies a large space.

[0005] Conventional electric vulcanization equipment includes a heating assembly and a power assembly that includes components such as a motor and rotates a fan component to realize the flow of a heating medium such as nitrogen gas within the vulcanization capsule. One of the problems with conventional electric vulcanization equipment is that components in the vulcanization equipment, especially drive mechanisms such as motors, are susceptible to the effects of the high temperature and pressure of the medium inside the vulcanization capsule, which shortens their lifespan.

[0006] Therefore, in the field of tire manufacturing, there is a need to further improve vulcanization equipment in order to resolve the problems that exist in the conventional vulcanization equipment described above. [Overview of the project]

[0007] This application was made to solve the problems present in the prior art described above. The purpose of this application is to provide tire vulcanization equipment that can solve the problem in the prior art in which high temperature and high pressure gases affect equipment such as motors and shorten their lifespan.

The vulcanization capsule, together with the upper clamping assembly, the lower clamping assembly, and the upper surface of the ring base, defines the vulcanization medium cavity in which the gaseous medium is contained.

The upper end of the central lever is fixedly connected to the upper clamping assembly, and the central lever is configured to move up and down relative to the lower clamping assembly.

[0010] In the tire vulcanizing apparatus described above, the rotating cylinder encloses the central lever, thereby placing the central lever in a sealed environment. Furthermore, the high-temperature, high-pressure medium from the vulcanizing medium cavity can be isolated within the rotating cylinder. In this way, the influence of the high-temperature, high-pressure medium on the rotational drive mechanism can be reduced or eliminated.

[0011] Preferably, one end of the stator assembly is connected directly or indirectly to the ring base in a sealed state, and the other end of the stator assembly is connected directly or indirectly to the end of the central lever that is away from the vulcanizing medium cavity in a sealed state.

[Modes for carrying out the invention]

[0037] The embodiments for carrying out the present invention will be described in detail below in accordance with the drawings. The drawings show only preferred examples of the present invention and do not limit the scope of the present invention. Those skilled in the art can make various obvious modifications, alterations, and equivalent substitutions to the present invention based on the embodiments shown in the drawings, all of which will fall within the scope of protection of the present invention.

[0038] In the following description of this application, terms such as "up" and "down" used to indicate direction and orientation are based on the orientation of the tire vulcanization equipment and its components as shown in the drawings, for the convenience of explanation. Furthermore, the orientation of the tire vulcanization equipment and its components as shown in the drawings is the general orientation in use, but it is not intended to exclude the possibility that the tire vulcanization equipment and its components may take on other orientations during processes such as transportation.

[0039] <Example 1> Figures 1-4 show a tire vulcanization apparatus 100 according to Embodiment 1 of the present application. As shown in Figure 1, the tire vulcanization apparatus 100 includes a vulcanization capsule 110, the lower clamped edge of the vulcanization capsule 110 being clamped by a lower clamping assembly 113, and the upper clamped edge of the vulcanization capsule 110 being clamped by an upper clamping assembly 114. The vulcanization mold 115 covers the vulcanization capsule 110 from the outside, thereby forming a vulcanization cavity between the vulcanization mold 115 and the vulcanization capsule 110, allowing the tire to be vulcanized to be placed in this vulcanization cavity.

[0040] The tire vulcanization equipment 100 further comprises a guide device used for opening and closing the tire vulcanization equipment during the tire vulcanization process. This guide device comprises a guide drive mechanism 111 and a central lever 112 connected to the guide drive mechanism 111. The guide device further comprises a first fixed seat 120, a second fixed seat 130, and a rotating cylinder 150. Of these, the first fixed seat 120 is suitable for external mounting to the first outer end of the central lever 112 and is suitable for connection to the guide drive mechanism 111. The second fixed seat 130 is suitable for external mounting to the second outer end of the central lever 112. A guide frame 140 is attached to the second fixed seat 130, and a guide hole is provided in the guide frame 140. The guide hole is provided coaxially with the central lever 112. A guide 141 is provided inside the guide hole. The rotating cylinder 150 is suitable for external mounting to the outside of the central lever 112. Furthermore, the rotating cylinder 150 includes at least a main body portion provided between the first fixed seat 120 and the second fixed seat 130, such that the central lever 112 is in a sealed environment as a whole.

[0041] In the exemplary structure shown in Figure 1, the ring base connected to the inside of the lower clamping assembly 113 functions as the second fixing seat 130. The second fixing seat 130 may also be provided in other forms; for example, the second fixing seat 130 may be an additional member connected to the inside or below the ring base.

[0042] As shown in the figure, the vulcanization capsule 110, together with the lower clamping assembly 113, the upper clamping assembly 114, and the upper surface of the ring base, defines the vulcanization medium cavity in which the gas medium is contained.

[0043] In the above embodiment, a rotating cylinder 150, a first fixing seat 120, and a second fixing seat 130 are provided on the outside of the central lever 112. The first fixing seat 120 and the second fixing seat 130 fix the rotating cylinder 150, and the first fixing seat 120 is provided at the end where the guide drive mechanism 111 and the central lever 112 are connected. As a result, the heat conducted from the heat source to the guide drive mechanism 111 is blocked by the second fixing seat 130, preventing the guide drive mechanism 111 from becoming unstable due to high temperatures. Furthermore, the provision of the rotating cylinder 150 places the central lever 112 in a sealed environment as a whole, further improving the stability of the movement of the central lever 112. In addition, the guide holes and guides 141 on the guide frame 140 function as positioning for the central lever 112, preventing the central lever 112 from shifting during movement, and further improving the stability of the guide device.

[0044] Some exemplary embodiments of the guide drive mechanism 111 include an oil cylinder, an electric cylinder, a water cylinder, an air cylinder, a screw, etc. The guide 141 may be a guide sleeve or a bearing, but in this embodiment, a copper guide sleeve is specifically used. The central lever 112 moves along the longitudinal direction, and the first fixed seat 120, the rotating cylinder 150, and the second fixed seat 130 are coaxial.

[0045] Based on the above-described embodiment, in several embodiments, if the inner diameter of the rotating cylinder 150 is a and the outer diameter of the central lever 112 is b, then a is greater than b. In this embodiment, the provision of the rotating cylinder 150 ensures that the central lever 112 moves under guidance in a sealed environment, while to some extent blocking heat conduction from the heat source. A first gap 153 exists between the rotating cylinder 150 and the central lever 112, and this first gap 153 communicates with the vulcanization medium cavity at its upper end. Furthermore, as schematically shown in Figure 1, a second gap 154 ​​is formed between the rotating cylinder 150 and the second fixed seat 130 (or ring base), and this second gap 154 ​​also communicates with the cavity inside the vulcanization capsule 110 at its upper end.

[0046] Based on the above embodiments, in some embodiments, a mounting groove 121 is provided on the inner wall of the first fixed seat 120, and the rotary drive mechanism 160 includes, for example, a motor provided in the mounting groove 121. Thus, the first fixed seat 120 also functions as a stator housing. The motor stator assembly includes the stator 162 and the stator housing. As shown more clearly in Figure 2, in a preferred configuration, the stator housing includes a base 122, an end cover 123, and a housing 124 located between the base 122 and the end cover 123, as shown in Figure 1. Optionally, seals are provided between the base 122 and the housing 124, and between the end cover 123 and the housing 124, to improve the airtightness of the internal space of the stator housing.

[0047] An annular cylinder 125 is further provided between the stator housing, which serves as the first fixed seat 120, and the ring base, which serves as the second fixed seat 130. The annular cylinder 125 is provided on the outer circumference of the rotating cylinder 150. The annular cylinder 125 can protect the rotating cylinder 150 and the components 112 located within it, and can also provide a seal between the ring base and the motor stator. Specifically, as shown in Figure 1, a first sealing material 171 is provided between the stator housing and the annular cylinder 125, and between the annular cylinder 125 and the ring base.

[0048] Furthermore, a second sealing material 172 is provided between the stator housing and the central lever 112. Below the stator housing, a support member 181 is provided to support the parts such as the first fixing seat 120 and the ring cylinder 125 described above. A second sealing material 172 is provided between the support member 181 and the base 122 of the stator housing. Alternatively, a second sealing material 172 may also be provided between the support member 181 and the central lever 112.

[0049] The first sealing material 171 and the second sealing material 172 connect the first gap 153 and the second gap 154 ​​at the lower end of the rotating cylinder 150 to form a U-shaped passage that communicates only with the vulcanizing medium cavity, while sealing the rest. This U-shaped passage seals in the high-temperature, high-pressure gas from the vulcanizing medium cavity inside the vulcanizing capsule 110.

[0050] In some embodiments, a third sealing material 173 is provided on the upper part of the rotating cylinder 150. The third sealing material 173 is provided between the rotating cylinder 150 and the ring base (or second fixed seat 130) at or near the upper end of the rotating cylinder 150. In these embodiments, the provision of the third sealing material 173 further ensures sealing and heat insulation effects. The third sealing material 173 isolates the first bearing chamber, which houses the bearing between the ring base and the rotating cylinder 150, from the high-temperature and high-pressure environment, preventing foreign matter and high-temperature and high-pressure gases from entering the first bearing chamber, thereby extending the life of the corresponding bearing.

[0051] The tire vulcanization equipment 100 is further equipped with a fourth sealing material 174, which is provided between the upper end of the ring cylinder 125 and the rotating cylinder 150, thereby improving the sealing performance of the first bearing chamber and preventing grease leakage in the first bearing chamber.

[0052] Furthermore, a fifth sealing material 175 is provided between the stator housing, specifically the base 122 of the stator housing, and the rotating cylinder 150. This fifth sealing material seals the second bearing chamber located at the lower end of the central lever 112 and the rotating cylinder 150, and prevents grease leakage from the second bearing chamber.

[0053] In some embodiments, as shown in Figure 2, the guide device further includes a rotary drive mechanism 160, which is connected to a rotating cylinder 150 and rotates the rotating cylinder 150. In these embodiments, the rotary drive mechanism 160 rotates the rotating cylinder 150, which in turn generates turbulence in the heat flow transmitted through the central lever 112, thereby further optimizing the heat insulation effect.

[0054] Next, refer to Figure 2. In some embodiments, a gap is provided between the inner wall of the first fixed seat 120 and the central lever 112, and the guide device further comprises a transmission sleeve 170 and a support bearing 180. The transmission sleeve 170 is provided between the first fixed seat 120 and the central lever 112 and is connected to the motor and the rotating cylinder 150. Multiple support bearings 180 are provided, and the multiple support bearings 180 may be provided above and below the motor, respectively. The support bearing 180 is externally fitted onto the transmission sleeve 170, and the fixed ring of the support bearing 180 is connected to the first fixed seat 120, and the movable ring of the support bearing 180 is connected to the transmission sleeve 170. The support bearing 180 ensures the stability of the drive of the rotating cylinder 150 by the motor, and the transmission sleeve 170 transmits the power of the motor, causing the rotating cylinder 150 to rotate and generate turbulence.

[0055] In the illustrated configuration, the transmission sleeve 170 and the rotating cylinder 150 are formed as a single unit. However, in some embodiments, the transmission sleeve 170 and the rotating cylinder 150 may be separate components and fixed together by a snap-fit ​​structure.

[0056] In some exemplary embodiments, one of the transmission sleeve 170 and the rotating cylinder 150 is provided with an outer tapered portion, and the other is provided with a corresponding inner tapered portion. The outer tapered portion and the inner tapered portion are connected by meshing, and the snap-fit ​​structure comprises the outer tapered portion and the inner tapered portion, and when the outer tapered portion and the inner tapered portion are combined, the corresponding tooth structures mesh. In this way, power from the transmission sleeve 170 can be transmitted to the rotating cylinder 150 while ensuring that the transmission sleeve 170 is concentric with the rotating cylinder 150. In some alternative embodiments, one of the transmission sleeve 170 and the rotating cylinder 150 is provided with a connecting hole, and the other is provided with a corresponding connecting segment. Specifically, the connecting segment may be a cylinder, a prism, or the like, and the connecting segment may be provided with a keyway or a tooth structure, and the connecting hole and the connecting segment may be matched and connected. In another alternative embodiment, one of the transmission sleeve 170 and the rotating cylinder 150 may be provided with transmission teeth, while the other may be provided with corresponding matching tooth surfaces.

[0057] Furthermore, in some embodiments, a heat source 191 is attached to the guide device, for example, the heat source 191 may be located above the second fixed seat 130. The upper end of the rotating cylinder 150 penetrates the second fixed seat 130, and a stirring component 152 is provided at the upper end of the rotating cylinder 150 to generate turbulence in the heat from the heat source 191. More specifically, as shown in the figure, both the heat source 191 and the stirring component 152 are provided in the internal space of the vulcanization capsule 110 and are arranged along the vertical direction.

[0058] Exemplary embodiments of the stirring component 152 may include blades, impellers, turbines, augers, plates, etc. By providing the stirring component 152, the effect of generating turbulence can be further optimized, and the effect of heat insulation can be optimized.

[0059] Furthermore, in some embodiments, as shown in Figure 4, the guide frame 140 includes a mounting plate 142. The shape of the mounting plate 142 is not limited, but it may be circular, polygonal, elliptical, or the like. Guide holes are provided in the mounting plate 142, and ventilation holes 143 are provided in the mounting plate 142 to ensure heat flow when the guide frame 140 is applied in a heat-conducting environment.

[0060] In a specific embodiment, the mounting plate 142 is fixed and connected to the second fixing base 130 by a support, spacer block, or the like. Here, the means for fixing and connecting are not limited as long as it can be guaranteed that the connection is fixed.

[0061] <Example 2> Figure 5 shows a tire vulcanization equipment 200 according to Embodiment 2 of the present application. Unless otherwise stated or contradictory, the specific configuration described for Embodiment 1 above also applies to Embodiment 2. The following describes in detail the configuration of Embodiment 2 that differs from that of Embodiment 1.

[0062] In Embodiment 2, the rotational drive mechanism comprises a rotor 261 and a stator assembly, similar to or the same as in Embodiment 1, and the stator assembly comprises a stator 262 provided on the outer circumference of the rotor 261 and facing the rotor 261. The first fixed seat of the tire vulcanizing equipment 200 functions as a stator housing, and the stator housing comprises a base 222, an end cover 223, and a housing 224 located between the base 222 and the end cover 223, and the stator 262 together with the stator housing constitutes the stator assembly.

[0063] In Embodiment 2, a sealing cylinder 226 is further provided between the stator assembly and the rotor. The upper end of the sealing cylinder 226 is in contact with or connected to the end cover 223 of the stator housing. Furthermore, it is preferable that a first sealing ring 276 is provided between the upper end of the sealing cylinder 226 and the end cover 223 of the stator housing. The lower end of the sealing cylinder 226 is supported or connected to the base 222 of the stator housing. Furthermore, it is preferable that a second sealing ring 277 is provided between the lower end of the sealing cylinder 226 and the base 222 of the stator housing.

[0064] In this way, the sealed cylinder 226 further isolates the stator 262, which is normally located on the outside in the form of an electromagnetic coil, from the high-temperature, high-pressure gas used for vulcanization in the tire vulcanization equipment 200. Furthermore, since the rotor 261 is usually composed of multiple permanent magnets, such as magnets or magnetic steel, and has a greater ability to withstand high-temperature and high-pressure environments than the stator 262 which is formed of an electromagnetic coil, even if a small amount of high-temperature, high-pressure gas leaks to the location where the motor is located, further isolating the stator 262 with the sealed cylinder 226 is sufficient to guarantee the normal operation of the motor.

[0065] Furthermore, in this embodiment, since an additional sealing barrier is formed by the sealing cylinder 226, the first sealing ring 276, and the second sealing ring 277, the sealing rings located between the base 222 and the housing 224, and between the end cover 223 and the housing 224 may be omitted.

[0066] <Example 3> Figures 6 and 7 show the tire vulcanization equipment 300 according to Embodiment 3 of the present application. Unless otherwise stated or contradictory, the specific configurations described for Embodiments 1 and 2 above also apply to Embodiment 3. The following describes in detail the configurations in Embodiment 3 that differ from those in Embodiments 1 and 2.

[0067] Figure 6 is a schematic cross-sectional view of the tire vulcanization equipment 300 of the present invention. The tire vulcanization equipment 300 includes a vulcanization capsule 311. The lower clamped edge of the vulcanization capsule 311 is clamped by a lower clamping assembly 312, and the upper clamped edge of the vulcanization capsule 311 is clamped by an upper clamping assembly 313. The tire vulcanization equipment 300 further includes a central lever 314. The upper end of the central lever 314 is fixedly connected to the upper clamping assembly 313, and the central lever 314 can move up and down in the vertical direction relative to the lower clamping assembly 312. In this way, the vulcanization capsule 311 can be contracted or expanded by the up and down movement of the central lever 314. Specifically, when the central lever 314 moves upward relative to the lower clamping assembly 312, the distance between the upper clamping assembly 313 and the lower clamping assembly 312 increases, and the vulcanization capsule 311 contracts. On the other hand, when the central lever 314 moves downward, the distance between the upper clamping assembly 313 and the lower clamping assembly 312 decreases, and the gas medium is filled into the vulcanization capsule 311, causing the vulcanization capsule 311 to expand.

[0068] The tire vulcanization equipment 300 further comprises a vulcanization mold 320. The vulcanization mold 320 covers the vulcanization capsule 311 from the outside, thereby forming a vulcanization cavity between the vulcanization mold 320 and the vulcanization capsule 311, allowing the tire to be vulcanized to be placed in this vulcanization cavity. During the vulcanization process, high-pressure nitrogen gas is introduced into the vulcanization capsule 311, and the nitrogen gas is heated, causing the vulcanization capsule 311 to expand and heat. In this way, pressure and heat are transferred to the tire from the inside by the vulcanization capsule 311 and from the outside by the vulcanization mold 320. Furthermore, it is preferable that the vulcanization mold 320 be further provided with additional heating components, such as electric heating components like heating wires, so that in addition to heating the tire from the inside by the vulcanization capsule 311, the tire can also be heated from the outside by the vulcanization mold 320.

[0069] In the preferred configuration shown in the illustration, the vulcanizing mold 320 is configured to be openable and closable, that is, it comprises an upper mold 321 and a lower mold 322 that can be opened and closed.

[0070] In the tire vulcanization equipment 300 of the present invention, an integrated media stirring device 310 is provided. The integrated media stirring device 310 is supported by a support member 315 of the tire vulcanization equipment 300. The support member 315 is preferably in the form of a support ring cylinder having an internal passage through which a central lever 314 can pass and extend.

[0071] Figure 7 is an exemplary cross-sectional view showing an integrated media stirring device 310, illustrating the specific configuration of the integrated media stirring device 310.

[0072] A preferred configuration of the illustrated integrated media agitator 310 includes a motor assembly 330 comprising a stator 331 and a rotor 332, wherein the stator 331 has an internal bore, and at least a portion of the rotor 332 is located within the internal bore of the stator 331. Furthermore, in the illustrated configuration, the stator 331 is located below the bottom of the ring base 340 and is supported by a support member 315, wherein a gap may be formed between the stator 331 and the bottom of the ring base 340. A guide frame 370 is further attached to the ring base 340, which is the same as the guide frame 140 in Embodiment 1.

[0073] While it is preferable for the stator 331 to be supported by the support member 315, in additional or alternative embodiments, the stator 331 may be fixedly connected to the bottom of the ring base 340, which contributes to fixing the stator 331.

[0074] One end of the rotor 332 is connected to an agitation component 351. An example of the agitation component 351 is a fan, and the agitation component 351 is located inside the vulcanization capsule 311 and can agitate the gas inside the vulcanization capsule 311. The gas inside the vulcanization capsule 311 is, for example, heated pressurized nitrogen gas. The integrated media agitator 2 further comprises a heating component 352 for heating the nitrogen gas in the vulcanization capsule 311. The heating component 352 may be, for example, an electrically heated component. Alternatively, the heating component 352 may be an inductance-type heating component.

[0075] Furthermore, as shown in the figure, by positioning the stator 331 below the bottom of the ring base 340, the ring base 340 can function as a separator between the stator 331 and the gas heated in the vulcanization capsule 311.

[0076] An electromagnetic winding is provided inside the stator 331, and when current flows through the electromagnetic winding, a magnetic field can be generated. Correspondingly, a permanent magnet 333 is provided on the outer part of the rotor 332 that faces the inside of the stator 331. When current flows through the electromagnetic winding of the stator 331, the generated magnetic field and the permanent magnet 333 in the rotor 332 interact with each other, causing the rotor 332 to rotate. As the rotor 332 rotates, the stirring component 351 also rotates, stirring the gas inside the vulcanization capsule 311. This gas is, for example, high-pressure nitrogen gas heated inside the vulcanization capsule 311, and this contributes to the uniform heating of the vulcanization capsule 311.

[0077] The integrated media agitator 310 further comprises a ring base 340, and one end of the rotor 332 connected to the agitator component 351 is rotatably positioned in the inner bore of the ring base 340 and is connected to the agitator component 351 by passing through the inner bore of the ring base 340. It is preferable that a bearing 334 is provided between the ring base 340 and the rotor 332, thereby facilitating the rotation of the rotor 332 relative to the ring base 340. It is preferable that the agitator component 351 and the heating component 352 are attached to the ring base 340 and provided with an axial gap between them.

[0078] Furthermore, as shown in Figure 7, in addition to the stator 331 being fixed to the support member 315, the stator 331 may be fixed to the ring base 340 as an alternative or additional configuration. The stator 331 is preferably fixed and sandwiched between the ring base 340 and the support member 315, and in such a configuration, a more secure positioning of the stator 331 can be better ensured.

[0079] To protect the motor assembly 330, and in particular the stator 331 of the motor assembly 330, the integrated media agitator 32 further comprises a stator housing 361, which is located outside the stator 331 and covers it. The stator housing 361 together with the stator 331 constitutes part of the stator assembly. The upper end of the stator housing 361 is fixedly connected to the ring base 340, and the lower end is detachably connected to the support member 315. Preferably, an insulating material 341 is further provided between the stator housing 361 and the ring base 340. The insulating material 341 prevents heat from the vulcanizing capsule 311 from being conducted downward to the support member 315, thereby reducing heat loss in the tire vulcanizing equipment 300 and further improving the overall thermal efficiency of the tire vulcanizing equipment 300.

[0080] Preferably, the lower end of the housing 361 and the support member 315 are connected by a flange structure, of which a first flange 316 is formed on the upper end of the support member 315 and a second flange 365 is formed on the lower end of the housing 361, and a plurality of bolts pass through holes in the first flange 16 and the second flange 65 to fix and connect them.

[0081] Preferably, the stator assembly further includes a sealing cylinder 362. The sealing cylinder 362 is provided between the stator 331 and the rotor 332, with its upper end connected to the ring base 340 and its lower end fixedly connected to the support member 315. Furthermore, to improve sealing performance, a first sealing material 363 is provided between the sealing cylinder 362 and the ring base 340, and a second sealing material 364 is provided between the sealing cylinder 362 and the support member 15. The second sealing material 364 may also be provided between the support member 315 and the oil cylinder located below, as shown in Figure 6, or between the central lever 314 and the oil cylinder.

[0082] The sealed cylinder 362 isolates the inside of the tire vulcanization equipment 300 from the outside, preventing contamination of the internal medium, such as the pressurized nitrogen gas in the vulcanization capsule 311, by the outside air. On the other hand, the sealed cylinder 362 prevents the internal medium of the tire vulcanization equipment 300 from overflowing, thus protecting the stator 331.

[0083] In the preferred configuration shown in the illustration, the upper and lower ends of the sealing cylinder 362 have relatively large thicknesses, which contributes to attachment to and sealing of the sealing cylinder 362. Furthermore, a stepped portion is provided at the lower end of the sealing cylinder 362, which facilitates supporting the sealing cylinder 362 on the support member 315.

[0084] An internal bore is formed in the sealing cylinder 362 through which the central lever 314 passes. Alternatively or additionally, the second sealing material 364 may be provided at or near the lower end of the sealing cylinder 362. This configuration prevents the gas medium in the vulcanization capsule 311 from flowing downward through the gap between the sealing cylinder 362 and the central lever 314. Furthermore, the ring base 340 may be provided with an inlet passage for the gas medium to enter the vulcanization capsule 311 and an outlet passage for the gas medium to exit the vulcanization capsule 311.

[0085] The provision of a sealing material between the sealing cylinder 362 and the central lever 314 is optional. In other embodiments of the present invention, no sealing material is provided between the sealing cylinder 362 and the central lever 314, and a gap surrounding the central lever 314 is formed between them, which can function as a passage for the gas medium to enter the vulcanization capsule 311 and a passage for it to exit the vulcanization capsule 311. This configuration also falls within the scope of the present invention. In this configuration, the gap between the sealing cylinder 362 and the central lever 314 may be 1 to 10 mm.

[0086] Additionally, as an option, a sixth sealing material 366 is provided on the outer surface of the ring base 340, and this sixth sealing material 366 forms a sealing configuration between the ring base 340 and the lower clamping assembly 312.

[0087] Furthermore, a clamp ring 342 is optionally provided at the upper end of the ring base 340 to form a space for housing a bearing between the central lever 314 and the ring base 340. A seventh sealing material 367 is provided between the central lever 314 and the clamp ring 342.

[0088] The choice of material for manufacturing the sealing cylinder 362 can better ensure the normal operation of the motor assembly 330. Specifically, the material for manufacturing the sealing cylinder 362 can be selected from carbon steel, stainless steel, ceramics, engineering plastics, and carbon fiber. More preferably, the thickness of the sealing cylinder 362, particularly the thickness of the portion directly interposed between the stator 331 and the rotor 332 in the sealing cylinder 362, may be in the range of 0.5 to 2 mm. Such a thickness of the sealing cylinder 362 can ensure thermal insulation efficiency while minimizing the impact on motor operation.

[0089] Returning to Figure 6, one specific method for connecting the integrated media agitator 310 to the tire vulcanization equipment 300 is that the integrated media agitator 310 is fixed and supported by the support member 315, and the lower clamping assembly 312 is connected to the ring base 340. Any known method can be used for connecting the lower clamping assembly 312 to the ring base 340, for example, screw fastening, a convex-groove structure, a locking structure, etc.

[0090] Furthermore, the central lever 314 extends through the integrated media stirring device 310 and can perform vertical movement along the integrated media stirring device 310. The inner bore of the rotor 332, together with the inner bore of the stirring component 351 and the inner bore of the heating component 352, forms the inner bore of the integrated media stirring device 310, and the central lever 314 extends through the inner bore of the integrated media stirring device 310.

[0091] <Example 4> Figure 8 shows an integrated media stirring device for a tire vulcanization facility according to Embodiment 4 of the present application. Unless otherwise stated or contradictory, the specific configurations described for Embodiments 1 to 3 above also apply to Embodiment 4. The following describes in detail the configurations in Embodiment 4 that differ from those in Embodiments 1 to 3.

[0092] As shown in Figure 8, in Embodiment 5, no sealing cylinder is provided. In this case, the first sealing material 463 is provided between the stator assembly and the ring base 440, specifically between the stator housing 461 and the ring base 440. The second sealing material 464 is provided between the stator assembly and the support member 415, specifically between the stator housing 461 and the support member 415. Alternatively, similar to Embodiment 3, the second sealing material 464 may be provided between the support member 415 and the oil cylinder, or between the central lever 414 and the oil cylinder.

[0093] <Example 5> Figure 9 shows an integrated media stirring device for a tire vulcanization facility according to Embodiment 5 of the present application. Unless otherwise stated or contradictory, the specific configurations described for Embodiments 1 to 4 above also apply to Embodiment 5. The following describes in detail the configurations in Embodiment 5 that differ from those in Embodiments 1 to 4.

[0094] In Embodiment 5, a sealing ring 570 is provided between the central lever 514 and the support member 515. Preferably, the sealing ring 570 is provided at the top of the support member 515 to seal the space between the central lever 514 and the support member 515. Preferably, an eighth sealing material 571 is provided on the inner and outer surfaces of the sealing ring 570, and this eighth sealing material 571 contributes to improving the sealing between the sealing ring 570 and the central lever 514 and between the sealing ring 570 and the support member 515.

[0095] Similar to Embodiment 4, a first sealing material 563 is provided between the ring base 540 and the stator housing 561. A second sealing material 564 is provided between the stator housing 561 and the support material 515.
