Description

[Technical Field]

[0001] The present application belongs to the field of tire manufacturing, specifically relates to tire vulcanization equipment, and more particularly to a media stirring device in the equipment. [Background technology]

[0002] The vulcanization process is commonly used in industrial production and can be used to improve the overall hardness of a material. In the field of tire manufacturing, it is necessary to perform a vulcanization process, especially on the outer tire, to harden the viscoelastic plastic rubber to form a usable tire product.

[0003] In conventional tire vulcanization processes, vulcanization is typically carried out by combining saturated steam and nitrogen gas. Specifically, the vulcanization process is as follows: First, an unvulcanized raw tire is placed between a sealed vulcanization capsule and a vulcanization mold. Then, saturated steam capable of supplying the heat necessary for vulcanization is introduced into the vulcanization capsule. Next, high-pressure nitrogen gas is introduced to provide the pressure necessary for vulcanization. The heat from the saturated steam and the pressure from the high-pressure nitrogen gas cause the vulcanization capsule to expand, pressing and heating the raw tire, thereby shaping and vulcanizing the raw tire.

[0004] One of the problems that can occur during the operation of a steam vulcanizer is that the steam entering the vulcanization capsule condenses, and the condensed water accumulates at the bottom of the vulcanization capsule, creating a relatively large temperature difference between the top and bottom of the vulcanization capsule and further affecting the vulcanization effect of the tire.In addition, to supply steam to the vulcanization capsule, a steam pipe must be installed, and this steam pipe takes up a large space.

[0005] In the prior art, there is an electric vulcanizing equipment that 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 in the vulcanizing capsule. One of the problems with conventional electric vulcanizing equipment is that the components in the vulcanizing equipment, particularly the driving mechanism such as the motor, are easily affected by the high-temperature and high-pressure medium inside the vulcanizing capsule, which shortens their lifespan.

[0006] Therefore, in the field of tire manufacturing, there is a need for further improving vulcanization equipment to eliminate the problems existing in conventional vulcanization equipment described above. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0037] The following detailed description of the preferred embodiments of the present invention is provided with reference to the accompanying drawings. The drawings are merely preferred examples of the present invention and are not intended to limit the scope of the present invention. Those skilled in the art may make various obvious modifications, variations, and equivalent substitutions to the present invention based on the embodiments shown in the drawings, all of which fall within the scope of protection of the present invention.

[0038] Hereinafter, terms indicating directions and orientations such as "up" and "down" used in the specific description of this application are based on the orientation of the tire vulcanizing equipment and its respective components shown in the drawings for the sake of convenience of explanation. Furthermore, the orientation of the tire vulcanizing equipment and its respective components shown in the drawings is the general orientation in use, but is not intended to exclude the tire vulcanizing equipment and its respective components from taking on other orientations, for example, during the process of transportation.

[0039] Example 1 1 to 4 show tire vulcanization equipment 100 according to a first embodiment of the present application. As shown in Fig. 1, the tire vulcanization equipment 100 includes a vulcanization capsule 110, the lower clamped edge of which is clamped by a lower clamping assembly 113, and the upper clamped edge of which is clamped by an upper clamping assembly 114. A 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, and a tire to be vulcanized can be placed in this vulcanization cavity.

[0040] The tire vulcanization equipment 100 further includes a guide device used for opening and closing the tire vulcanization equipment during the tire vulcanization process. The guide device includes a guide drive mechanism 111 and a central lever 112 connected to the guide drive mechanism 111. The guide device also includes a first fixed seat 120, a second fixed seat 130, and a rotating tube 150. The first fixed seat 120 is adapted to be fitted onto a first outer end of the central lever 112 and is adapted to be connected to the guide drive mechanism 111. The second fixed seat 130 is adapted to be fitted onto a second outer end of the central lever 112. A guide frame 140 is attached to the second fixed seat 130, and the guide frame 140 has a guide hole. The guide hole is coaxial with the central lever 112. A guide 141 is provided within the guide hole. The rotating tube 150 is adapted to be fitted onto the outer side of the central lever 112. The rotating barrel 150 also includes at least a main body portion disposed between the first fixed seat 120 and the second fixed seat 130 so that the central lever 112 is in a totally sealed environment.

[0041] 1, a ring base connected to the inside of the lower clamping assembly 113 functions as the second fixed seat 130. It goes without saying that the second fixed seat 130 may be provided in other forms, for example, the second fixed seat 130 may be an additional member connected to the inside or below the ring base.

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

[0043] In the above embodiment, the rotating cylinder 150, the first fixing seat 120, and the 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. The first fixing seat 120 is provided at the end where the guide drive mechanism 111 and the central lever 112 are connected. Therefore, the second fixing seat 130 blocks heat conduction from the heat source to the guide drive mechanism 111, preventing the guide drive mechanism 111 from becoming unstable due to high temperatures. In addition, 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. Furthermore, the guide hole and guide 141 on the guide frame 140 function to position 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. In addition, the central lever 112 moves along the vertical direction, and the first fixed seat 120, the rotating cylinder 150, and the second fixed seat 130 are coaxially related to each other.

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

[0046] Based on the above-described embodiments, in some embodiments, the inner wall of the first fixed seat 120 is provided with a mounting groove 121, and the rotary drive mechanism 160 includes, for example, a motor provided in the mounting groove 121. As a result, the first fixed seat 120 also functions as a stator housing. The stator assembly of the motor includes the stator 162 and the stator housing. As shown more clearly in FIG. 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 FIG. 1 . Optionally, sealing structures may be provided between the base 122 and the housing 124, and between the end cover 123 and the housing 124, to improve the sealing of the internal space of the stator housing.

[0047] A ring cylinder 125 is further provided between the stator housing serving as the first fixed seat 120 and the ring base serving as the second fixed seat 130. The ring cylinder 125 is provided on the outer periphery of the rotating cylinder 150. The ring cylinder 125 can protect the rotating cylinder 150 and the 112 located therein, and can also provide a seal between the ring base and the stator of the motor. Specifically, as shown in FIG. 1, first seals 171 are provided between the stator housing and the ring cylinder 125, and between the ring cylinder 125 and the ring base.

[0048] Furthermore, a second seal 172 is provided between the stator housing and the central lever 112. A support 181 is provided below the stator housing to support components such as the first fixed seat 120 and the annular tube 125. The second seal 172 is provided between the support 181 and the base 122 of the stator housing. The second seal 172 may also be provided between the support 181 and the central lever 112.

[0049] The first gap 153 and the second gap 154 are connected to each other at the lower end of the rotating cylinder 150 by the first sealant 171 and the second sealant 172 to form a U-shaped passage, which is in communication with only the vulcanization medium cavity and the remaining part is sealed. The U-shaped passage seals in high-temperature and high-pressure gas from the vulcanization medium cavity in the vulcanization capsule 110.

[0050] In some embodiments, a third seal 173 is provided on the upper part of the rotating cylinder 150. The third seal 173 is provided at or near the upper end of the rotating cylinder 150, between the rotating cylinder 150 and the ring base (or the second fixed seat 130). In this embodiment, the provision of the third seal 173 further ensures sealing and heat insulation effects. The third seal 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 gas from entering the first bearing chamber and thereby extending the life of the corresponding bearing.

[0051] The tire vulcanizing equipment 100 is further provided with a fourth sealant 174, which is provided between the upper end of the ring tube 125 and the rotating tube 150, and improves the sealing performance of the first bearing chamber and prevents grease leakage from the first bearing chamber.

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

[0053] 2, the guide device further includes a rotary drive mechanism 160, which is connected to the rotating barrel 150 and drives the rotating barrel 150 to rotate. In this embodiment, the rotary drive mechanism 160 drives the rotating barrel 150 to rotate, and the rotating barrel 150 generates turbulence in the heat flow moving along the central lever 112, thereby further optimizing the heat insulation effect.

[0054] Continuing to refer to FIG. 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 includes 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 barrel 150. A plurality of support bearings 180 may be provided, and the plurality of support bearings 180 may be provided above and below the motor, respectively. The support bearing 180 is 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 motor driving the rotating barrel 150, and the transmission sleeve 170 transmits the power of the motor, causing the rotating barrel 150 to rotate and generate turbulence.

[0055] In the illustrated configuration, the transmission sleeve 170 and the rotating barrel 150 are integrally formed, but in some embodiments, the transmission sleeve 170 and the rotating barrel 150 may be separate bodies and secured together by a snap-fit structure.

[0056] In some exemplary embodiments, one of the transmission sleeve 170 and the rotating barrel 150 has an external tapered portion, and the other has a corresponding internal tapered portion. The external tapered portion and the internal tapered portion are interlocked and connected, and a snap-fit structure is provided on the external tapered portion and the internal tapered portion, and when the external tapered portion and the internal tapered portion are combined, corresponding tooth structures interlock. In this way, the power of the transmission sleeve 170 can be transmitted to the rotating barrel 150 while ensuring that the transmission sleeve 170 is concentric with the rotating barrel 150. In some alternative embodiments, one of the transmission sleeve 170 and the rotating barrel 150 has a connecting hole, and the other has a corresponding connecting segment. Specifically, the connecting segment may have a cylindrical or rectangular shape, and the connecting segment may have a key groove or a tooth structure, so that the connecting hole and the connecting segment can be mated and connected. In another alternative embodiment, one of the transmission sleeve 170 and the rotatable barrel 150 may be provided with transmission teeth and 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, and for example, the heat source 191 may be located above the second fixed seat 130. The upper end of the rotating cylinder 150 passes through the second fixed seat 130, and an agitating member 152 is provided at the upper end of the rotating cylinder 150 to generate turbulence in the heat generated by the heat source 191. More specifically, as shown in the figure, the heat source 191 and the agitating member 152 are both provided in the internal space of the vulcanization capsule 110 and are arranged along the vertical direction.

[0058] Exemplary embodiments of the agitating element 152 may be blades, impellers, turbines, augers, plates, etc., and the agitating element 152 may be provided to further optimize the turbulence and thermal insulation effects.

[0059] 4, the guide frame 140 includes a mounting plate 142. The shape of the mounting plate 142 is not limited, and may be circular, polygonal, elliptical, etc. The guide holes are provided in the mounting plate 142, and the mounting plate 142 is also provided with ventilation holes 143 to ensure heat circulation when the guide frame 140 is used in a thermally conductive environment.

[0060] In a specific embodiment, the mounting plate 142 is fixedly connected to the second fixed seat 130 by means of a support, spacer block, or the like, and the means for fixing and connecting is not limited as long as the fixed connection can be ensured.

[0063] In the second embodiment, a sealing cylinder 226 is further provided between the stator assembly and the rotor. The upper end of the sealing cylinder 226 abuts against or is connected to the end cover 223 of the stator housing. Furthermore, a first seal ring 276 is preferably 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 by or connected to the base 222 of the stator housing. Furthermore, a second seal ring 277 is preferably 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 can further isolate the stator 262, which is usually 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. Also, the rotor 261 is usually made up of a plurality of permanent magnets, such as magnets or magnetic steel, and its ability to withstand high-temperature, high-pressure environments is stronger than that of the stator 262, which is made up of an electromagnetic coil. Therefore, 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 ensure normal operation of the motor.

[0065] Furthermore, in this embodiment, since an additional sealing barrier is formed by the sealing sleeve 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 6 and 7 show a tire vulcanizing equipment 300 according to Example 3 of the present application. Unless stated otherwise or contradictory, the specific configurations described in relation to Examples 1 and 2 above also apply to Example 3. Below, the configurations in Example 3 that differ from Examples 1 and 2 will be specifically described.

[0067] FIG. 6 is a cross-sectional view schematically illustrating a tire vulcanization equipment 300 according to 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 relative to the lower clamping assembly 312. In this manner, the upward and downward movement of the central lever 314 can cause the vulcanization capsule 311 to contract or expand. 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, causing the vulcanization capsule 311 to contract. 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 becomes smaller, and the gas medium is filled into the vulcanizing capsule 311, causing the vulcanizing capsule 311 to expand.

[0068] The tire vulcanization equipment 300 further includes 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, and the tire to be vulcanized can 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. In addition, the vulcanization mold 320 is preferably further equipped with an additional heating element, such as an electric heating element such as a heating wire, so that the tire can be heated not only from the inside by the vulcanization capsule 311 but also from the outside by the vulcanization mold 320.

[0069] In the illustrated preferred configuration, the vulcanization mold 320 is configured to be openable and closable, that is, it includes an upper mold 321 and a lower mold 322 that can be opened and closed.

[0070] The tire vulcanizing equipment 300 of the present application is provided with an integrated media agitator 310. The integrated media agitator 310 is supported by a support member 315 of the tire vulcanizing equipment 300. The support member 315 is preferably in the form of a support ring having an internal passage through which the central lever 314 can extend.

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

[0072] A preferred configuration of the illustrated integrated media stirring device 310 includes a motor assembly 330 having a stator 331 and a rotor 332, the stator 331 having an inner bore, and at least a portion of the rotor 332 being located in the inner 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 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, and the guide frame is the same as the guide frame 140 in the first embodiment.

[0073] Although it is preferred that the stator 331 be supported by the support 315, in additional or alternative embodiments, the stator 331 may be fixedly connected to the bottom of the ring base 340, thereby helping to secure the stator 331.

[0074] One end of the rotor 332 is connected to an agitator 351. An example of the agitator 351 is a fan. The agitator 351 is located inside the vulcanizing capsule 311 and can agitate the gas inside the vulcanizing capsule 311. The gas inside the vulcanizing capsule 311 is, for example, heated pressurized nitrogen gas. The integrated medium agitator 2 further includes a heating element 352 to heat the nitrogen gas inside the vulcanizing capsule 311. The heating element 352 may be, for example, an electric heating element. Alternatively, the heating element 352 may be an inductance-type heating element.

[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 serve to separate the stator 331 from the gas heated in the vulcanization capsule 311.

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

[0077] The integrated media stirring device 310 further includes a ring base 340, and one end of the rotor 332, which is connected to the stirring member 351, is rotatably disposed in an inner hole of the ring base 340 and passes through the inner hole of the ring base 340 to be connected to the stirring member 351. A bearing 334 is preferably provided between the ring base 340 and the rotor 332, thereby facilitating rotation of the rotor 332 relative to the ring base 340. The stirring member 351 and the heating member 352 are preferably attached to the ring base 340 and spaced apart in the axial direction.

[0078] 7, the stator 331 may be fixed to the ring base 340 as an alternative or additional form to fixing the stator 331 to the support 315. The stator 331 is preferably fixedly sandwiched between the ring base 340 and the support 315, and such a configuration can better ensure that the stator 331 is firmly positioned.

[0079] To protect the motor assembly 330, and in particular the stator 331 of the motor assembly 330, the integrated media stirring device 32 further includes a stator housing 361, which is disposed 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 315. It is preferable that a heat insulating material 341 be further provided between the stator housing 361 and the ring base 340. The heat insulating material 341 prevents heat from the vulcanization capsule 311 from being conducted downward to the support 315, thereby reducing heat loss in the tire vulcanization equipment 300 and further improving the overall thermal efficiency of the tire vulcanization equipment 300.

[0080] Preferably, the lower end of the housing 361 and the support 315 are connected by a flange structure, in which a first flange 316 is formed at the upper end of the support 315 and a second flange 365 is formed at 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 securely connect them.

[0081] Preferably, the stator assembly further includes a sealing cylinder 362. The sealing cylinder 362 is disposed 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 315. To improve sealing performance, a first seal 363 is disposed between the sealing cylinder 362 and the ring base 340, and a second seal 364 is disposed between the sealing cylinder 362 and the support 315. The second seal 364 may also be disposed between the support 315 and the oil cylinder located below, or between the central lever 314 and the oil cylinder, as shown in FIG. 6 .

[0082] The sealed cylinder 362 isolates the interior of the tire vulcanizing equipment 300 from the outside, preventing the media inside the tire vulcanizing equipment 300, such as the pressurized nitrogen gas in the vulcanizing capsule 311, from being contaminated by the outside air. On the other hand, the sealed cylinder 362 prevents the media inside the tire vulcanizing equipment 300 from overflowing, thereby protecting the stator 331.

[0083] In the preferred configuration shown in the drawings, the upper and lower ends of the sealing cylinder 362 have a relatively large thickness, which can contribute to the attachment and sealing of the sealing cylinder 362. Furthermore, a step is provided at the lower end of the sealing cylinder 362, which can make it easier to support the sealing cylinder 362 on the support member 315.

[0084] The sealing cylinder 362 has an inner hole through which the central lever 314 passes. Alternatively or additionally, the second seal 364 may be provided at or near the lower end of the sealing cylinder 362. This configuration can prevent the gas medium in the vulcanizing 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 through which the gas medium enters the vulcanizing capsule 311 and an outlet passage through which the gas medium exits the vulcanizing capsule 311.

[0085] It should be noted that providing a seal between the sealing tube 362 and the central lever 314 is optional. In another embodiment of the present application, no seal is provided between the sealing tube 362 and the central lever 314, and a gap is formed therebetween surrounding the central lever 314, which can function as a passage for the gas medium to enter the vulcanization capsule 311 and to exit the vulcanization capsule 311. This embodiment also falls within the scope of the present application. The gap between the sealing tube 362 and the central lever 314 may be 1 to 10 mm.

[0086] Additionally, a sixth seal 366 is optionally provided on the outer surface of the ring base 340 to form a seal between the ring base 340 and the lower clamping assembly 312 .

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

[0088] The selection of the 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 of the sealing cylinder 362 directly interposed between the stator 331 and the rotor 332, may be within a range of 0.5 to 2 mm. This thickness of the sealing cylinder 362 can ensure the efficiency of thermal insulation while minimizing the impact on the operation of the motor.

[0089] Returning to Fig. 6, one specific means for connecting the integrated media agitator 310 and the tire vulcanizing equipment 300 is that the integrated media agitator 310 is fixedly supported by a support member 315, and the lower clamping assembly 312 is connected to the ring base 340. Any known means may be used for connecting the lower clamping assembly 312 and the ring base 340, such as screw fastening, a convex ring-concave groove structure, or a locking structure.

[0090] In addition, the central lever 314 extends through the integrated media stirring device 310 and can move up and down in the vertical direction relative to the integrated media stirring device 310, and the inner hole of the rotor 332, together with the inner hole of the stirring part 351 and the inner hole of the heating part 352, forms the inner hole of the integrated media stirring device 310, and the central lever 314 extends through the inner hole of the integrated media stirring device 310.

[0091] Example 4 8 shows an integrated medium stirring device for tire vulcanization equipment according to Example 4 of the present application. Unless there is a contrary statement or contradiction, the specific configurations described in relation to Examples 1 to 3 above also apply to Example 4. Below, the configurations in Example 4 that differ from Examples 1 to 3 will be specifically described.

[0092] 8, in the fifth embodiment, a sealing cylinder is not provided. In this case, a first seal 463 is provided between the stator assembly and the ring base 440, specifically between the stator housing 461 and the ring base 440. A second seal 464 is provided between the stator assembly and the support 415, specifically between the stator housing 461 and the support 415. Alternatively, as in the third embodiment, the second seal 464 may be provided between the support 415 and the oil cylinder, or between the central lever 414 and the oil cylinder.

Unless there is a contrary statement or contradiction, the specific configurations described in relation to Examples 1 to 4 above also apply to Example 5. Below, the configurations in Example 5 that differ from Examples 1 to 4 will be specifically described.

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

[0095] As in the fourth embodiment, a first seal 563 is provided between the ring base 540 and the stator housing 561. A second seal 564 is provided between the stator housing 561 and the support member 515.
