A vulcanizing equipment Technical Field

[0001] The present invention relates to the technical field of vulcanization equipment, in particular to a vulcanization device, and in particular to the design of a heating device in the vulcanization device. Background Art

[0002] In industrial production, vulcanization is often used to increase the overall hardness of certain materials.

[0003] Take tire vulcanization, for example. This refers to the vulcanization of the tire casing, performed using a mold pressurization method. Before vulcanization, the tire is a viscoelastic, plastic rubber that is easily deformed, weak, and useless. Vulcanization solidifies this plastic rubber into a highly elastic, useful rubber.

[0004] In the prior art, there are mainly two types of vulcanization equipment, one is electric heating vulcanization equipment, and the other is steam heating vulcanization equipment.

[0005] In electrically heated vulcanization equipment, nitrogen or another inert gas is used as the medium. This medium is injected into the equipment's sealed curing bladder and heated by heating devices located inside or outside the bladder. The tire to be cured is placed between the bladder and the mold. Inside the bladder, a heating assembly heats the medium, generating a high-temperature medium. This high-temperature medium acts on the inside of the bladder to provide the heat required for vulcanization. The nitrogen also provides the necessary pressure during vulcanization. The bladder expands and compresses the green tire, which, in conjunction with the vulcanizer, shapes and cures the green tire, enhancing its strength.

[0006] In addition, a stirring component is provided in the curing bladder, which can stir the gas medium in the curing bladder, improve the temperature uniformity in the curing bladder, and promote heat exchange between the gas medium and the curing bladder.

[0007] The aforementioned existing vulcanization equipment has been plagued by several issues during use. One of these issues is that the high-temperature gas inside the vulcanization bladder sometimes experiences poor circulation, leading to significant temperature differences across the bladder and uneven tire vulcanization, impacting vulcanization quality. Furthermore, the vulcanization equipment's internal heating device is susceptible to damage during operation, making it difficult to maintain, especially for components such as bearings.

[0008] Therefore, there is a need to improve the vulcanization equipment, especially to improve the heating device thereof, so as to improve the uniformity of the temperature inside the vulcanization bladder.

[0009] Summary of the Invention

[0010] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the high-temperature nitrogen gas inside the curing bladder cannot circulate, resulting in large temperature differences between different parts of the curing bladder, causing uneven tire curing and affecting tire curing quality. Another problem to be solved by the present invention is to facilitate the maintenance of the curing equipment, especially the heating device therein.

[0011] To this end, the present invention provides a vulcanization equipment, comprising:

[0012] The vulcanization mold is openable and closable, and has a vulcanization cavity formed inside;

[0013] a curing bladder, adapted to be placed in the curing cavity;

[0014] a support assembly comprising a central rod and a clamping device disposed on the central rod, the clamping device being adapted to sealingly mount the curing bladder in the cavity;

[0015] The clamping device includes a ring seat, the center rod is inserted into the ring seat, a window is provided on the ring seat, and a receiving chamber connected to the window is provided inside the ring seat. The vulcanizing equipment also includes:

[0016] a rotating member disposed in the accommodation chamber and rotatably connected to the first side wall of the accommodation chamber, wherein an electromagnetic assembly is disposed between the rotating member and the second side wall of the accommodation chamber, and the electromagnetic assembly is adapted to be energized to rotate the rotating member;

[0017] an air outlet member connected to the rotating member and extending out of the window;

[0018] A heating component is arranged in the curing bladder.

[0019] The structure of the vulcanization equipment has the advantage that a receiving chamber is provided on the ring seat, and the rotating part is provided in the receiving chamber, so that one side wall of the rotating part is rotatably connected to the corresponding side wall of the receiving chamber, and an electromagnetic component is provided between the other side wall of the rotating part and the corresponding side wall of the receiving chamber. When the electromagnetic component is partially energized, electromagnetic induction is generated between the ring seat with the receiving chamber and the rotor through the electromagnetic component, which eventually causes the rotating part to rotate, driving the air outlet part to rotate to drain the high-temperature gas medium in the vulcanization bladder, so that the high-temperature gas medium can circulate, ensuring that the temperature of each part inside the vulcanization bladder is balanced, and avoiding uneven tire vulcanization.

[0020] Furthermore, compared to methods in which a fan structure is provided within the vulcanizing bladder and driven to rotate to drain a high-temperature gaseous medium such as high-temperature nitrogen, the fan structure is typically powered by a drive motor, which requires a series of mechanical transmissions, such as a drive shaft and gear transmissions, to ultimately drive the fan structure. This results in a relatively complex structure and is prone to component failure during this process, thus affecting the normal operation of the vulcanizing equipment. In this application, the electromagnetic induction effect between the ring seat and the rotating member replaces the traditional mechanical transmission, thereby overcoming the drawbacks of prior art vulcanizing equipment that utilize a series of mechanical transmissions to drive the fan structure, resulting in a relatively complex structure and the tendency for component failure to occur, thus affecting the normal operation of the vulcanizing equipment.

[0021] Optionally, the electromagnetic component includes:

[0022] a permanent magnet, disposed on a side wall of the rotating member;

[0023] An armature winding is arranged on the second side wall corresponding to the permanent magnet, and the armature winding is suitable for being energized to drive the rotating member to rotate.

[0024] The advantage of this structure is that, through the cooperation between the permanent magnet and the armature winding, when the armature winding is energized, an electromagnetic induction effect is generated between the permanent magnet and the armature winding, thereby driving the rotating part to rotate, and further driving the air outlet part connected to the rotating part to rotate.

[0025] Optionally, there is a preset gap between the rotating member and the second side wall of the accommodating chamber, a recess is formed on one of the rotating member and the second side wall, and the electromagnetic component is suitable for being arranged in the recess.

[0026] The advantage of this structure is that there is a preset gap between the rotating part and the second side wall of the accommodating chamber, which ensures that the rotating part and the ring seat provided with the accommodating chamber can rotate smoothly relative to each other; a recessed portion is provided to provide an installation position for the electromagnetic component while ensuring the clearance fit between the rotating part and most parts of the second side wall, thereby ensuring the compactness of the overall structure of the vulcanizing equipment and reducing the possibility of equipment damage due to loose structure during use.

[0027] Optionally, the heating component is located on the outer peripheral side of the air outlet member and is arranged on the ring seat.

[0028] The advantage of this structure is that, since the air outlet is arranged in a manner that allows for lateral air discharge, and the heating component is located on the outer periphery of the air outlet, the gas medium guided by the air outlet flows directly into the heating component, undergoing sufficient heat exchange with the heating component to generate a high-temperature gas medium, thereby improving the heat exchange efficiency and, in turn, the heat exchange efficiency between the high-temperature gas medium and the vulcanization bladder. The ring seat provides an installation location for the heating component. In addition, compared to the case where the air outlet is arranged on the outer periphery of the heating component, the air outlet in this structure is closer to the center rod, resulting in a smaller torque, less power required, and less noise. Moreover, the heating component is away from the center rod, avoiding heat radiation to the center rod, which could damage the center rod.

[0029] Optionally, the heating component includes:

[0030] A support cylinder is arranged on the ring seat, and a mounting groove is arranged on the outer side of the support cylinder;

[0031] The heater is arranged in the installation groove, and a flow portion is formed on the support cylinder, and the flow portion is suitable for guiding the heating medium gas.

[0032] The advantage of this structure is that the installation groove provided on the support tube provides an installation position for the subsequent heater, and the flow portion is a plurality of through holes provided on the support tube. The gas medium guided from the air outlet piece flows directly into the heating component and then is guided out of the heating component from the through holes.

[0033] Optionally, the heater has a multi-layer spacing structure or a spiral structure, and the circulation portion is provided at a spacing position corresponding to two adjacent layers of the heater.

[0034] The advantage of this structure is that there is a gap space between any two adjacent layers of the heater with a multi-layer spacing structure or a spiral structure, and the multi-layer circulation part is arranged corresponding to the gap space, that is, the through hole is connected with the gap space, so that any layer of the circulation part is located between the two layers of heater structure. When the gas medium circulates layer by layer, the heating efficiency of the heating component for the gas medium is improved, so that the temperature field in the vulcanization bladder is more uniform.

[0035] Optionally, a flow guide cover is provided on the outside of the heating component, the open end of the flow guide cover is connected to the flow portion, and the contracted end of the flow guide cover is arranged toward the inner wall of the vulcanization bladder to guide the heating medium gas to the inner wall of the vulcanization bladder.

[0036] The structural advantage of setting up a guide cover is that an open end and a contraction end are formed on the guide cover. The gas medium passing through the heating component flows into the contraction end from the open end and flows out from the contraction end. The flow rate and pressure of the outflowing gas medium are increased. The heat exchange efficiency between the gas medium and the vulcanization bladder is improved at a high flow rate. At the same time, the gas medium is guided to the inner wall of the vulcanization bladder, further improving the uniformity of the temperature field in the vulcanization bladder.

[0037] Optionally, the blades of the air outlet member are deflected toward one side relative to the radial direction of the air outlet member.

[0038] The advantage of this structure is that the blades act on the gas medium, making the gas medium circulate more fully and further improving the uniformity of the temperature field in the curing bladder.

[0039] Optionally, an air intake pipeline and / or an exhaust pipeline are further included and are arranged on the ring seat.

[0040] The advantage of this structure is that the air intake and exhaust lines run through the entire ring seat, allowing the gas medium to enter the curing bladder smoothly from the outside and be discharged at the appropriate time. In actual application, only one pipe can be installed as the air guide, or two air intake and exhaust lines can be installed at the same time.

[0041] Optionally, a gap is formed between the bottom of the rotating member and the accommodating chamber.

[0042] The advantage of this structure is that a gap is formed between the bottom of the rotating member and the accommodating chamber, which facilitates the relative rotation of the rotating member and the ring seat provided with the accommodating chamber, while further improving the uniformity of the temperature field in the vulcanizing bladder.

[0043] The present invention also relates to a heating device in a vulcanizing device, which includes a ring seat, a heating assembly, and an air outlet member such as an agitating member. The ring seat includes an outer support tube and an inner support tube inside the outer support tube, the outer support tube and the inner support tube being fixed together at their lower ends, and the upper ends of the outer support tube and the inner support tube being spaced apart from each other, thereby forming a semi-enclosed cavity with one end open. A rotating member is provided inside the outer support tube so that the rotating member is located in the semi-enclosed cavity and is capable of rotating relative to the outer support tube, wherein the heating assembly is mounted on the outer support tube, the agitating member is mounted on the rotating member and is located inside the heating assembly, and a fixed tube is provided inside the rotating member.

[0044] The rotation of the rotating part relative to the outer support tube can be achieved through the following structure: a permanent magnet is arranged at the lower part of the rotating part, and an armature winding is arranged at a position of the outer support tube corresponding to the permanent magnet, so that the magnetic field generated when the armature winding is energized interacts with the magnetic field of the permanent magnet to cause the rotating part to rotate.

[0045] The advantage of the heating device structure described above is that the semi-enclosed chamber formed by the outer support tube and the inner support tube accommodates the rotating member and the stirring member (e.g., a fan) connected to the rotating member. During maintenance, the rotating member and the stirring member can be easily removed from the semi-enclosed chamber, thereby leaving sufficient space for maintenance operations, thereby facilitating maintenance operations. Furthermore, this structure can improve the efficiency of disassembly and assembly of the rotating member and the stirring member, thereby improving maintenance efficiency.

[0046] Preferably, the fixed cylinder is rotatably assembled on the outer side of the inner support cylinder, and at least one bearing is provided between the fixed cylinder and the inner support cylinder, and the rotating member is detachably fixedly connected to the fixed cylinder.

[0047] Specifically, the rotating member and the fixed cylinder are connected together by a fixing screw. Alternatively, the rotating member and the fixed cylinder can also be detachably fixed together in other ways.

[0048] The advantage of this structure is that the rotating member and its connected components can be easily removed from the heating device for easy maintenance and replacement. In addition, after the rotating member is removed, a larger space is left in the semi-enclosed cavity, which facilitates the maintenance and replacement of other components of the heating device.

[0049] In another preferred configuration, the fixed cylinder is removably mounted on the inner support cylinder, and at least one bearing is disposed between the fixed cylinder and the rotating member. This configuration offers the advantage that the rotating member, fixed cylinder, agitating member, and bearing can be removably positioned as a single unit within the semi-enclosed chamber. During maintenance, the unit can be removed and installed from the opening of the semi-enclosed chamber, further improving assembly and disassembly efficiency while ensuring component assembly precision and contributing to a more compact structure.

[0050] Preferably, the device further comprises a fixing component, through which the fixing cylinder is fixed in the semi-enclosed cavity. The advantage of providing the fixing component is that it helps to achieve detachable installation of the fixing cylinder.

[0051] For example, the fixing component can be an inner convex ring detachably connected to the top of the inner support tube, and the inner convex ring extends radially outward beyond the inner support tube, wherein the portion of the inner convex ring extending beyond the inner support tube is pressed against the top of the fixing tube to fix the fixing tube in place.

[0052] In another example, the fixing component is a flange formed on the top of the fixing cylinder. When the fixing cylinder is installed in the semi-enclosed cavity, the flange rests on the top of the inner support cylinder and can be detachably fixedly connected to the inner support cylinder.

[0053] Preferably, a step is formed on the outer surface of the fixed cylinder, one end of the bearing abuts the step, and the other end of the bearing abuts a fixed pressure plate. This structure has the advantage of effectively securing the bearing. Furthermore, the provision of the fixed pressure plate prevents the lubricating oil in the bearing from scattering during rotation, which could cause lubrication failure of the bearing.

[0054] Preferably, the heating assembly includes a heating cylinder, on which an electric heater is mounted. The electric heater here is, for example, an electromagnetic induction coil, an electric heating tube, etc.

[0055] More specifically, a groove is provided on the outer surface of the heating tube, and the electric heater is wound in the groove. Furthermore, a first vent extending radially through the heating tube can also be formed in the heating tube.

[0056] Preferably, a deflector is provided on the outside of the heating assembly, with the upper surface of the deflector gradually decreasing in height radially outward, thereby forming a generally umbrella-shaped structure. Furthermore, a second vent may be formed on the deflector near the heating assembly, and a third vent may be formed on the deflector away from the heating assembly. The first vent communicates with the second vent, and the second vent communicates with the third vent.

[0057] The advantage of this structure is that, by providing the guide plate of such a structure, the flow of the gas medium in the vulcanization bladder can be promoted, thereby further improving the temperature uniformity in the vulcanization bladder. Preferably, the first vent is provided opposite to the second vent.

[0058] The heating device is also provided with an air inlet passage, which extends through the outer support tube and the heating tube.

[0059] The advantage of this structure is that the gas medium can be injected from the outside into the vulcanizing bladder of the vulcanizing equipment equipped with the heating device.

[0060] The present invention also provides a vulcanization apparatus comprising: a vulcanization bladder; a lower clamping member that clamps a lower edge of the vulcanization bladder; an upper clamping member that clamps an upper edge of the vulcanization bladder; and a center rod whose upper end is fixedly connected to the upper clamping member and capable of lifting and lowering the lower clamping member. The vulcanization apparatus also includes the aforementioned heating device, wherein the lower clamping member is fixedly connected to the outer side of the outer support cylinder.

[0061] The curing equipment further includes a mold, which is disposed outside the curing bladder, forming a curing space between the mold and the curing bladder. The mold is an openable and closable mold. Specifically, the mold may include an upper mold and a lower mold. Furthermore, the mold may be a two-half movable mold, a top-opening movable mold, a bottom-opening movable mold, or the like. BRIEF DESCRIPTION OF THE DRAWINGS

[0098] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0099] In the description of the present invention, it should be noted that terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate and simplify the description of the present invention and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0100] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0101] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0102] An existing tire vulcanization process uses nitrogen as the heating medium. Specifically, a green tire is placed between a sealed curing bladder and a curing mold. Nitrogen is introduced into the bladder and heated by a heating assembly within the bladder. This high-temperature nitrogen acts on the inside of the bladder, providing the heat required for vulcanization. The nitrogen also provides the pressure required for vulcanization. The bladder expands and compresses the green tire, which is then shaped and vulcanized in conjunction with the vulcanizer to improve tire strength. Furthermore, a fan is installed within the bladder to drive the high-temperature nitrogen, distributing it evenly throughout the bladder and ensuring a uniform temperature distribution within the bladder.

[0103] However, the above solution has the following problems: the high-temperature nitrogen inside the curing bladder cannot circulate, resulting in large temperature differences between various parts inside the curing bladder, causing uneven tire curing and affecting tire curing quality.

[0104] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the high-temperature nitrogen inside the vulcanization bladder cannot circulate, resulting in large temperature differences between various parts inside the vulcanization bladder, causing uneven tire vulcanization and affecting the tire vulcanization quality.

[0105] <First embodiment>

[0106] A first embodiment of the present invention provides a vulcanization apparatus 100, as shown in Figures 1 to 3, comprising: a vulcanization mold, a rotating member 110, a vulcanization bladder 120, a center rod 130, a clamping device 140, a ring seat 141, a window 1411, a receiving chamber 1412, an electromagnetic assembly 150, an air outlet member 160, a heating assembly 170, etc. The heating device of the vulcanization apparatus 100 includes the ring seat 141, the air outlet member 160, and the heating assembly 170.

[0107] The vulcanization mold (not shown in the figure) can be opened and closed, and a vulcanization cavity is formed inside.

[0108] Specifically, the vulcanization mold is an upper and lower structure. After the upper vulcanization mold is separated from the upper and lower ends in cooperation with the liftable center rod 130 and part of the clamping device 140, the center rod 130 can rise to retract the vulcanization bladder 120, and place the green tire to be vulcanized in the vulcanization cavity. When the upper vulcanization mold is lowered, the upper and lower ends of the vulcanization mold are closed. During the vulcanization process, the vulcanizer provides the vulcanization mold with a clamping force.

[0109] Furthermore, it should be noted that the vulcanization mold in this embodiment is a two-half mold. In some other embodiments, the vulcanization mold can also be a two-half flexible mold, an upper-opening flexible mold, a lower-opening flexible mold, or other structural forms.

[0110] The curing bladder 120 is suitable for being placed in the curing cavity.

[0111] Specifically, the curing bladder 120 is a hollow, thin-walled rubber product used in a vulcanizer. It is used to hold the green tire to be vulcanized and then introduce a gaseous medium, which, in conjunction with the vulcanizer, performs shaping and vulcanization operations. The gaseous medium can be an inert gas or a rare gas, as long as it does not participate in redox reactions. In this embodiment, nitrogen can be further selected.

[0112] The support assembly includes a central rod 130 and a clamping device 140 disposed on the central rod 130 . The clamping device 140 is suitable for sealingly mounting the curing bladder 120 in the cavity.

[0113] Specifically, after the upper and lower ends of the vulcanization mold are separated, the center rod 130 can be raised to place the green tire to be vulcanized in the vulcanization cavity. The center rod 130 can then be lowered, and the upper and lower ends of the vulcanization mold are closed when the upper end vulcanization mold is lowered. The clamping device 140 provided on the center rod 130 is suitable for sealing the vulcanization bladder 120 to prevent leakage of the gaseous medium.

[0114] The clamping device 140 includes a ring seat 141 . The center rod 130 is passed through the ring seat 141 . A window 1411 is provided on the ring seat 141 . An accommodating chamber 1412 communicating with the window 1411 is provided inside the ring seat 141 .

[0115] Specifically, as shown in Figures 1 and 2, ring seat 141 is located at the bottom center of the vulcanization mold, providing clearance fit with center rod 130 and providing mounting space for center rod 130. A sealing device (not shown) is provided between center rod 130 and ring seat 141 to prevent leakage of the gaseous medium. Ring seat 141 has an annular groove-shaped receiving chamber, namely, receiving chamber 1412. Receiving chamber 1412 has an opening, namely, window 1411, formed on one side of ring seat 141 near vulcanization bladder 120. The subsequent rotating member 110 and electromagnetic assembly 150 are adapted to be installed into receiving chamber 1412 through window 1411.

[0116] The rotating member 110 is disposed in the accommodating chamber 1412 and is rotatably connected to the first side wall 1413 of the accommodating chamber 1412 . An electromagnetic assembly 150 is disposed between the rotating member 110 and the second side wall 1414 of the accommodating chamber 1412 . The electromagnetic assembly 150 is suitable for being energized to rotate the rotating member 110 .

[0117] 2 , the first side wall 1413 of the accommodating chamber 1412 is the inner wall close to the center rod 130, and the second side wall 1414 of the accommodating chamber 1412 is the outer wall away from the center rod 130. The rotating member 110 is an annular cylindrical structure as a whole, and is installed into the accommodating chamber 1412 from the window 1411. The inner wall of the rotating member 110 and the first side wall 1413 of the accommodating chamber 1412 are rotatably connected through a number of bearings 1415. An electromagnetic assembly 150 suitable for generating electromagnetic induction is provided between the outer wall of the rotating member 110 and the second side wall 1414 of the accommodating chamber 1412. When the electromagnetic assembly 150 is partially energized, electromagnetic induction is generated between the ring seat 141 with the accommodating chamber 1412 and the rotor through the electromagnetic assembly 150, thereby causing the rotating member 110 to rotate.

[0118] As another embodiment, the first side wall 1413 of the accommodating chamber 1412 is the outer wall on the side away from the center rod 130, and the second side wall 1414 of the accommodating chamber 1412 is the inner wall on the side close to the center rod 130. The rotating part 110 is an annular cylindrical structure as a whole and is installed in the accommodating chamber 1412 from the window 1411. The outer wall of the rotating part 110 is rotatably connected to the first side wall 1413 of the accommodating chamber 1412 through a number of bearings 1415; an electromagnetic component 150 suitable for generating electromagnetic induction is provided between the inner wall of the rotating part 110 and the second side wall 1414 of the accommodating chamber 1412.

[0119] The air outlet member 160 is connected to the rotating member 110 and extends out of the window 1411 .

[0120] Specifically, the air outlet member 160 is connected to the rotating member 110 and is suitable for rotating synchronously with the rotating member 110 when the rotating member 110 rotates through the electromagnetic induction effect, so that the energized electromagnetic component 150 cooperates with the rotating member 110 as a transmission structure to transmit power for the rotation of the air outlet member 160.

[0121] Furthermore, the air outlet member 160 may be in the form of an open impeller, a closed impeller, a turbine, a fan, or the like.

[0122] The heating assembly 170 is disposed in the curing bladder 120 .

[0123] Specifically, the heating component 170 is suitable for heating the gas medium. By providing the heating component 170 , the temperature of the gas medium is increased to form a high-temperature gas medium suitable for vulcanization operations.

[0124] This embodiment provides a vulcanization equipment, in which a receiving chamber 1412 is provided on a ring seat 141, and a rotating member 110 is provided in the receiving chamber 1412, so that one side wall of the rotating member 110 is rotatably connected to the corresponding side wall of the receiving chamber 1412, and an electromagnetic assembly 150 is provided between the other side wall of the rotating member 110 and the corresponding side wall of the receiving chamber 1412. When the electromagnetic assembly 150 is partially energized, electromagnetic induction is generated between the ring seat 141 with the receiving chamber 1412 and the rotating member 110 through the electromagnetic assembly 150, thereby causing the rotating member 110 to rotate, driving the air outlet member 160 to rotate to drain the high-temperature gas medium in the vulcanization bladder 120, and draining the high-temperature gas medium to various positions on the inner wall of the vulcanization bladder 120, so that various parts inside the vulcanization bladder 120 are evenly heated, thereby overcoming the defect in the prior art that the high-temperature nitrogen inside the vulcanization bladder cannot circulate, resulting in a large temperature difference among various parts inside the vulcanization bladder, resulting in uneven tire vulcanization and affecting the tire vulcanization quality.

[0125] Based on the above embodiment, as a further limited embodiment, as shown in FIG2 , the electromagnetic assembly 150 includes: a permanent magnet 151 and an armature winding 152 .

[0126] A permanent magnet 151 is disposed on a side wall of the rotating member 110, and an armature winding 152 is disposed on the second side wall 1414 in correspondence with the permanent magnet 151. The armature winding 152 is adapted to be energized to drive the rotating member 110 to rotate. Specifically, a lead hole may be provided on the ring seat 141, through which a wire passes to connect to the armature winding 152. Through the cooperation between the permanent magnet 151 and the armature winding 152, when the armature winding 152 is energized, an electromagnetic induction effect is generated between the permanent magnet 151 and the armature winding 152, thereby driving the rotating member 110 to rotate, and further driving the air outlet member 160 connected to the rotating member 110 to rotate.

[0127] On the basis of the above embodiment, as a further limited embodiment, as shown in Figure 2, a preset gap is set between the rotating member 110 and the second side wall 1414 of the accommodating chamber 1412; a recess 180 is formed on the rotating member 110 and one of the second side walls 1414, and the electromagnetic component 150 is suitable for being set in the recess 180.

[0128] Specifically, a preset gap is provided between the rotating member 110 and the second side wall 1414 of the accommodating chamber 1412 to ensure smooth relative rotation between the rotating member 110 and the ring seat 141 provided with the accommodating chamber 1412; a recessed portion 180 is provided to provide an installation position for the electromagnetic assembly 150, thereby ensuring the compactness of the overall structure of the vulcanization equipment.

[0129] On the basis of the above embodiment, as a further limited embodiment, as shown in FIG. 1 and FIG. 2 , the heating assembly 170 is located on the outer peripheral side of the air outlet member 160 and is provided on the ring seat 141 .

[0130] Specifically, because the air outlet member 160 is arranged to discharge air horizontally, the location of the heating assembly 170 on the outer periphery of the air outlet member 160 facilitates direct flow of the gas medium directed by the air outlet member 160 into the heating assembly 170, where it undergoes sufficient heat exchange with the heating assembly 170 to generate high-temperature gas medium, thereby improving heat exchange efficiency and, in turn, the heat exchange efficiency between the high-temperature gas medium and the curing bladder 120. The ring seat 141 provides a mounting location for the heating assembly 170.

[0131] On the basis of the above embodiment, as a further limited embodiment, as shown in FIG2 , the heating assembly 170 includes: a support tube 171 , a heater 172 , a circulation portion 173 , and the like.

[0132] A support tube 171 is disposed on the ring seat 141. A mounting groove is provided on the outer side of the support tube 171. The support tube 171 is positioned on the outer periphery of the air outlet member 160. A heater 172 is disposed in the mounting groove. A flow passage 173 is formed on the support tube 171. The flow passage 173 is adapted to guide the gaseous medium. The support tube 171 can also function as a heating tube, for example.

[0133] Specifically, the mounting groove provided on the support tube 171 provides an installation position for the subsequent heater 172, and the flow portion 173 is a plurality of through holes provided on the support tube 171. The gas medium guided from the air outlet member 160 flows directly into the heating component 170 and then is guided out of the heating component 170 from the through holes.

[0134] As another embodiment, the support tube 171 is a frame structure, the heater 172 is arranged on the frame structure, and the circulation portion 173 is formed by the gap portion of the frame structure. The gas medium guided from the air outlet member 160 directly flows into the heating component 170 and then is guided out of the heating component 170 from the gap portion.

[0135] On the basis of the above embodiment, as a further limited embodiment, as shown in FIG2 , the heater 172 is a multi-layer spaced structure or a spiral structure, and the flow portion 173 is provided at a spaced position corresponding to two adjacent layers of the heater 172 .

[0136] Specifically, there is a gap space between any two adjacent layers of the heater 172 with a multi-layer spacing structure or a spiral structure, and the multi-layer circulation portion 173 is arranged corresponding to the gap space, that is, the through hole is connected to the gap space, so that any layer of the circulation portion 173 is located between the two layers of the heater 172 structure. When the gas medium circulates layer by layer, the heating efficiency of the heating component 170 for the gas medium is improved, so that the temperature field in the vulcanization bladder 120 is more uniform.

[0137] On the basis of the above embodiment, as a further limited embodiment, as shown in Figures 1 and 2, a flow guide cover 190 is provided on the outside of the heating assembly 170, the open end 191 of the flow guide cover 190 is connected to the flow portion 173, and the contracted end 192 of the flow guide cover 190 is arranged toward the inner wall of the vulcanization bladder 120 to guide the gas medium to the inner wall of the vulcanization bladder 120.

[0138] Specifically, an open end 191 and a contracted end 192 are formed on the air guide 190. The gas medium passing through the heating assembly 170 flows into the contracted end 192 from the open end 191 and flows out from the contracted end 192. The flow rate and pressure of the outflowing gas medium are increased. The heat exchange efficiency between the gas medium and the vulcanization bladder 120 is improved at a high flow rate. At the same time, the gas medium is guided toward the inner wall of the vulcanization bladder 2, further improving the uniformity of the temperature field in the vulcanization bladder 120.

[0139] Based on the above embodiment, as a further limited embodiment, as shown in FIG. 3 , the blades 161 of the air outlet member 160 are deflected toward one side relative to the radial direction of the air outlet member 160 .

[0140] Specifically, the blades 161 act on the gas medium, making the gas medium circulate more fully, further improving the uniformity of the temperature field in the curing bladder 120 .

[0141] On the basis of the above embodiment, as a further limited embodiment, as shown in FIG. 1 and FIG. 2 , the vulcanization equipment further includes an air intake line 111 and / or an exhaust line 112 , which are disposed on a ring seat 141 .

[0142] Specifically, the air intake line 111 and the exhaust line 112 run through the entire ring seat 141, allowing the gaseous medium to smoothly enter the curing bladder 120 from the outside and be discharged in a timely manner. In actual applications, only one line can be provided as the air guide line, or both the air intake line 111 and the exhaust line 112 can be provided.

[0143] On the basis of the above embodiment, as a further limited embodiment, as shown in FIG. 2 , a gap 113 is formed between the bottom of the rotating member 1 and the accommodation chamber 1412 .

[0144] Specifically, a gap 113 is formed between the bottom of the rotating member 110 and the accommodating chamber 1412 , which facilitates smooth relative rotation between the rotating member 110 and the ring seat 141 provided with the accommodating chamber 1412 , while further improving the uniformity of the temperature field in the curing bladder 120 .

[0145] On the basis of the above embodiment, as a further limited embodiment, as shown in FIG1 , the clamping device 140 further includes: a lower clamping ring 142 , an upper clamping ring 143 , a lower pressure ring 144 and an upper pressure ring 145 .

[0146] The lower clamping ring 142 is mounted on the ring seat 141 , and the lower end of the vulcanizing bladder 120 is clamped between the lower clamping ring 142 and the vulcanizing mold.

[0147] The upper clamping ring 143 is mounted on the protruding end of the center rod 130 , and the upper end of the vulcanizing bladder 120 is clamped between the upper clamping ring 143 and the vulcanizing mold.

[0148] A lower pressure ring 144 is provided between the lower clamping ring 142 and the vulcanization mold, and an upper pressure ring 145 is provided between the upper clamping ring 143 and the vulcanization mold.

[0149] Specifically, the clamping device 140 is provided to clamp and seal the vulcanization bladder 120 to prevent leakage of the heating medium gas in the vulcanization bladder 120 , which may reduce the vulcanization quality of the vulcanization equipment or even make the vulcanization operation impossible.

[0150] <Second embodiment>

[0151] FIG4 shows a vulcanization apparatus 200 according to a second embodiment of the present invention. Unless otherwise specified or incompatible, the specific structures described above with respect to the first embodiment also apply to the second embodiment. In the following description, identical structures will not be described in detail, and the structures that differ from the first embodiment will be specifically described.

[0152] Similar to the first embodiment, the vulcanizing equipment 200 of the second embodiment also includes components such as a rotating member 210 , a vulcanizing bladder, a center rod, a clamping device, a ring seat 230 , an air outlet member 260 , and a heating assembly 270 .

[0153] In the exemplary structure shown in FIG4 , the ring seat 230 includes an outer support tube 231 and an inner support tube 232. The outer support tube 231 and the inner support tube 232 are fixedly connected at their lower ends, for example, by a screw-thread structure or by welding. Alternatively, as shown in the first embodiment, the outer support tube 231 and the inner support tube 232 can be formed as a single body. The upper ends of the outer support tube 231 and the inner support tube 232 are separated from each other. Thus, the outer support tube 231 and the inner support tube 232 form a semi-enclosed cavity with one end open.

[0154] The heating assembly 270 is fixedly mounted on the outer support cylinder 231, while the air outlet member 260 is fixedly connected to the rotating member 210. A fixed cylinder 233 is disposed inside the rotating member 210, with a bearing 241 disposed between the fixed cylinder 233 and the inner support cylinder 232. The fixed cylinder 233 is mounted on the outer circumference of the inner support cylinder 232 via the bearing 241 and is capable of rotating within the semi-enclosed cavity between the outer support cylinder 231 and the inner support cylinder 232. The fixed cylinder 233 can be rotatably mounted on the inner support cylinder 232, for example, by means of an interference fit.

[0155] The rotating member 210 is fixedly connected to the fixed cylinder 233. For example, in the exemplary structure shown in the figure, the rotating member 210 is detachably fixedly connected to the fixed cylinder 233 via a connecting member 251. The connecting member 251 can be, for example, a set screw that passes through aligned screw holes in the rotating member 210 and the fixed cylinder 233, thereby fixedly connecting the rotating member 210 and the fixed cylinder 233. In addition to the set screw, the rotating member 210 and the fixed cylinder 233 can also be detachably connected by other means, such as a snap-fit ​​structure, an internal-external thread structure, etc.

[0156] This structure allows for convenient maintenance of the various components of the heating device. For example, if the rotating member 210 needs to be modified or replaced, the rotating member 210 and its connected air outlet member 260 can be easily removed from the semi-enclosed chamber between the outer support tube 231 and the inner support tube 232 by removing or releasing the connecting member between the rotating member 210 and the fixed tube 233. Furthermore, after the rotating member 210 is removed, sufficient space is left between the outer support tube 231 and the inner support tube 232, allowing for maintenance and replacement of other components of the heating device.

[0157] <Third embodiment>

[0158] Figures 5 and 6 illustrate a vulcanization apparatus 300 according to a third embodiment of the present invention. Unless otherwise specified or in conflict, the specific structures described above with respect to the first and second embodiments also apply to the third embodiment. In the following description, identical structures will not be described in detail, and the structures that differ from the first and second embodiments will be specifically described.

[0159] Figure 5 shows a cross-sectional view of the curing apparatus 300 of the present application. The curing apparatus 300 includes a curing bladder 311, and a mold 320 disposed outside the curing bladder 311, forming a curing space between the mold 320 and the curing bladder 311. Preferably, a heating device, such as a heating wire, is disposed within the mold 320. Thus, during the curing process, the tire to be cured is placed between the curing bladder 311 and the mold 320, with the curing bladder 311 heating and the mold 320 heating and pressurizing the tire from the inside, while the mold 320 heats and pressurizes the tire from the outside.

[0160] Preferably, the mold 320 can be an openable and closable mold 320, for example, the mold 320 includes an upper mold 321 and a lower mold 322. In addition, the mold 320 can also be other forms of openable and closable molds, such as a two-half movable mold, an upper open movable mold, a lower open movable mold, and the like.

[0161] The lower edge of the vulcanized rubber 311 is clamped by the lower clamping member 312, and the upper edge of the vulcanizing bladder 311 is clamped by the upper clamping member 313. Preferably, the lower clamping member 312 is in sealing engagement with the lower edge of the vulcanizing bladder 311, and the upper clamping member 313 is in sealing engagement with the upper edge of the vulcanizing bladder 311, thereby forming a sealed space within the vulcanizing bladder 311.

[0162] The curing apparatus 300 also includes a center rod 314, the upper end of which is fixedly connected to the upper clamping member 313. The center rod 314 is capable of vertical movement relative to the lower clamping member 312. The upward and downward movement of the center rod 314 enables the expansion and contraction of the curing bladder 11. After a tire is loaded onto the curing bladder 311, the center rod 314 rises, increasing the distance between the upper clamping member 313 and the lower clamping member 312, causing the curing bladder 311 to contract, allowing the tire to be placed outside the curing bladder 311. After the tire is placed, the center rod 314 descends, shortening the distance between the upper clamping member 313 and the lower clamping member 312. Gas is then injected into the curing bladder 311 from outside the curing apparatus 300, causing the bladder 311 to expand and apply pressure to the tire from within. After the curing bladder 311 is collapsed again, the cured tire can be removed from the curing bladder 311 .

[0163] A heating device 310 is further provided in the vulcanizing equipment 300 , and a lower clamping component 312 is installed outside the heating device 310 .

[0164] FIG6 illustrates the specific structure of the heating device 310. The heating device 310 includes a ring base 330 having an outer support tube 331 and an inner support tube 332. The outer support tube 331 and the inner support tube 332 are fixedly connected at their lower ends, for example, by a screw-and-thread arrangement, or welded together, or the outer support tube 331 and the inner support tube 332 are integrally formed at their lower ends. The upper ends of the outer support tube 331 and the inner support tube 332 are separated from each other. Thus, the outer support tube 331 and the inner support tube 332 form a semi-enclosed cavity with one end open, such as the upper end shown in the figure. The lower clamping member 312 is fixedly connected to the outer side of the outer support tube 331. The inner support tube 332 has an inner cavity extending through it. The center rod 314 extends through this inner cavity and can move up and down within it.

[0165] A heating assembly 340 is fixedly mounted on the outer support tube 331. This heating assembly 340 includes a heating tube 341, on which an electric heater 342 is mounted. In one exemplary configuration, a groove is formed on the outer side of the heating tube 341, and the electric heater 342 is specifically an electric heating component such as an electromagnetic induction coil or an electric heating tube wound within the groove. Electricity is supplied to the electric heater 342 to generate heat.

[0166] In addition, at least one first vent 343 may be provided in the heating tube 341. The first vent 343 extends generally radially through the heating tube 341 and may be a slot. In the preferred configuration shown in the figure, multiple first vents 343 are provided longitudinally along the heating tube 341. The first vents 343 allow the gaseous medium to flow through the heating assembly 340, thereby improving the heating efficiency of the gaseous medium.

[0167] A rotating member 351 is disposed inside the outer support tube 331. As can be seen in the figure, the rotating member 351 is positioned within a semi-enclosed cavity formed between the outer support tube 331 and the inner support tube 332. A permanent magnet 352 is located below the rotating member 351, and an armature winding 334 is located on the corresponding portion of the outer support tube 331. When power is supplied to the armature winding 334, the magnetic field generated by the armature winding 334 interacts with the magnetic field generated by the permanent magnet 352, driving the rotating member 351 to rotate. A fan 353 is mounted on the rotating member 351, acting as both an air outlet and a stirring element. Specifically, the rotation of the rotating member 351 drives the fan 353 to rotate, blowing the heated gaseous medium into the vulcanizing bladder 311. Furthermore, the rotation of the fan 353 stirs the gaseous medium within the vulcanizing bladder 311, promoting uniform temperature distribution within the bladder 311. In order to reduce the obstruction to the rotation of the rotating member 351 , the rotating member 351 and the fan 353 are positioned to form a certain gap between them and the outer support cylinder 331 and the heating assembly 340 .

[0168] A fixed cylinder 333 is disposed inside the rotating member 351. This fixed cylinder 333 is positioned against the inner support cylinder 332 and is specifically removably mounted on the inner support cylinder 332. A bearing 354 is disposed between the fixed cylinder 333 and the rotating member 351 to facilitate rotation of the rotating member 351 relative to the fixed cylinder 333. A single bearing 354 may be provided, or multiple bearings 354 may be provided. For example, the figure shows two bearings 354 arranged in a vertical direction. A stepped portion is formed on the outer surface of the fixed cylinder 333 to facilitate mounting of the bearing 354.

[0169] The fixed cylinder 333 is fixed relative to the inner support cylinder 332 by an inner convex ring 335. Specifically, as shown in the figure, the inner convex ring 335 is mounted on the top of the inner support cylinder 332 and is connected to the inner support cylinder 332 by a detachable fastener such as a screw. In addition, the inner convex ring 335 extends radially outward relative to the inner support cylinder 332. The portion of the inner convex ring 335 that extends beyond the inner support cylinder 332 can be pressed against the top of the fixed cylinder 333, thereby fixing the fixed cylinder 333 in place.

[0170] Alternatively, a flange may be formed on the top of the fixing cylinder 333, which rests on the top of the inner support cylinder 332 when the fixing cylinder 333 is installed in the semi-enclosed cavity, and the flange may then be detachably connected to the inner support cylinder 332 using fasteners such as screws.

[0171] Preferably, one side of the bearing 354 abuts against the step portion, and a fixed pressure plate 355 is provided on the other end of the bearing 354 to thereby fix the position of the bearing 354. Further, providing the fixed pressure plate 355 also helps prevent the lubricating oil of the bearing 354 from splashing during the rotation process.

[0172] When the inner convex ring 335 is removed from the inner support tube 332, for example by unscrewing the screws connecting them, the fixed tube 333, along with the rotating member 351, the fan 353, and the bearing 354, can be removed as a whole from the semi-enclosed chamber formed by the outer support tube 331 and the inner support tube 332. This facilitates maintenance of the various components of the heating device 310. Furthermore, the integrated disassembly of the fixed tube 333, the rotating member 351, the fan 353, and the bearing 354 facilitates assembly and disassembly of the heating device 310. Testing has shown that assembly and disassembly efficiency can be increased by 60%, while ensuring the precise assembly of the various components and improving the compactness of the structure.

[0173] Preferably, a deflector plate 360 ​​is disposed outside the heating assembly 340. The upper surface of the deflector plate 360 ​​gradually decreases in height radially outward, forming a generally umbrella-shaped structure. Furthermore, a second vent 361 is disposed on the side of the deflector plate 360 ​​proximal to the heating assembly 340, and a third vent 362 is formed on the portion of the deflector plate 360 ​​distal to the heating assembly 340. The first vent 343 communicates with the second vent 361, preferably facing the second vent 361, and the second vent 361 communicates with the third vent 362. The ring seat 330, the deflector plate 360, and the lower clamping member 312 define a gas flow path. Specifically, the rotation of the fan 353 drives the gas flow, causing the gas to sequentially flow through the first vent 343, the second vent 361, and the third vent 362, and enter the curing bladder 311. The gaseous medium reenters the semi-enclosed cavity of the ring seat 330 after completing heat exchange with the curing bladder 11. The guide plate 360 ​​of such a structure can promote the flow of the gaseous medium in the curing bladder 311, thereby improving temperature uniformity.

[0174] Furthermore, an air inlet passage 336 is provided in the heating device 310 for injecting a gaseous medium from outside the vulcanization equipment 300 into the vulcanization bladder 311. Specifically, the air inlet passage 336 extends through the outer support tube 331 and the heating tube 341 mounted on the outer support tube 331, as shown by the dotted line in FIG6 .

[0175] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
