Description

Technical Field

[0001] This application belongs to the field of tire manufacturing technology, and specifically relates to a tire vulcanization device for vulcanizing tires. Background Technology

[0002] Vulcanization is widely used in industrial production. Through vulcanization, the overall hardness of certain materials can be increased, such as the hardness of rubber. Rubber is one of the main materials used in tire manufacturing. Before vulcanization, the rubber-supported tire is a viscoelastic, malleable rubber that is easily deformed and has low strength. After vulcanization, the rubber hardens and acquires higher strength and elasticity.

[0003] Traditional tire vulcanization processes typically employ a combination of saturated steam and nitrogen. The process is as follows: First, the unvulcanized green tire is placed between a sealed vulcanizing bladder and a vulcanizing mold. Then, saturated steam is introduced into the vulcanizing bladder, providing the heat required for vulcanization. Next, high-pressure nitrogen is introduced to provide the necessary pressure for vulcanization. Under the combined heat of the saturated steam and the pressure of the nitrogen, the vulcanizing bladder expands, compresses, and heats the green tire, thus shaping and vulcanizing it.

[0004] One problem that arises during the operation of a steam vulcanizing machine is that the steam entering the vulcanizing bladder condenses. The condensate accumulates at the bottom of the vulcanizing bladder, creating a significant temperature difference between the upper and lower parts, which in turn affects the vulcanization effect of the tire. Furthermore, supplying steam to the vulcanizing bladder requires the installation of steam pipelines, which occupy considerable space.

[0005] To address these issues with steam vulcanizing machines, existing technologies have proposed electric vulcanizing systems. These systems include heating and ventilation devices to heat the medium within a sealed chamber. Furthermore, they include an agitator, such as a fan or impeller, driven by a motor or other mechanism to force the flow of the gaseous medium. In existing electric vulcanizing systems, the sealed chamber is filled with the gaseous medium, and the motor, agitator, heating device, and other components are all located within this chamber. This necessitates wiring inside the vulcanizing capsule to power the heating device. This can lead to interference between the rotating agitator and the contraction of the vulcanizing capsule, or the wiring can result in clutter and excessive space occupation within the capsule.

[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] Please refer to Figures 1-3 The present invention provides a tire vulcanizing equipment, including a vulcanizing capsule 1, a lower clamping assembly 2, an upper clamping assembly 3, a vulcanizing mold, and a center rod 4.

[0037] The lower clamping component 2 clamps the lower edge of the vulcanizing capsule 1, and the upper clamping component 3 clamps the upper edge of the vulcanizing capsule 1. This creates a closed space within the vulcanizing capsule 1, which can be filled with a gaseous medium such as pressurized nitrogen. The gaseous medium then heats and pressurizes the inside of the tire to be vulcanized, which is wrapped around the vulcanizing capsule 1. Other inert gases can also be used, but nitrogen is a preferred example considering cost and other factors.

[0038] The vulcanizing mold covers the tire from the outside. A heating device 5, such as an electric heater, is also provided in the vulcanizing mold, allowing the tire to be heated from the outside. The vulcanizing mold is an openable mold, comprising an upper mold and a lower mold.

[0039] The upper end of the central rod 4 is fixedly connected to the upper clamping assembly 3. The central rod 4 can move vertically relative to the lower clamping assembly 2, thereby achieving the contraction and expansion of the vulcanizing capsule 1. Specifically, when the central rod 4 moves upward, the distance between the lower clamping assembly 2 and the upper clamping assembly 3 increases, thus reducing the radius of the vulcanizing capsule 1 and causing it to contract. When the central rod 4 moves downward, the distance between the lower clamping assembly 2 and the upper clamping assembly 3 decreases, increasing the radius of the vulcanizing capsule 1. After the vulcanizing capsule 1 is filled with a gaseous medium, it expands. During the vulcanization process, the tire to be vulcanized is first placed on the vulcanizing capsule 1, and then the central rod 4 descends, causing the vulcanizing capsule 1 to expand, thus tightly wrapping the tire around the vulcanizing capsule 1. A lifting drive device is connected to the lower end of the central rod 4 to drive the central rod 4 to move up and down. The lifting drive device can be a hydraulic cylinder, pneumatic cylinder, etc.

[0040] The tire vulcanizing equipment also includes a ring seat 9, with a lower clamping assembly 2 installed on the outer circumference of the ring seat 9. The ring seat 9 has an inner hole. A supporting ring cylinder 18 is fixedly installed at the lower end of the ring seat 9. A rotating cylinder 19 is installed inside the supporting ring cylinder 18.

A bearing is installed between the rotating cylinder 19 and the inner hole of the ring seat 9. The central rod 4 passes through the rotating cylinder 19 and enters the vulcanizing capsule 1.

[0041] A heating device 5 and an agitator 6 are also provided inside the vulcanizing capsule 1. The heating device 5 is preferably fixedly mounted on the ring seat 9 and axially spaced from the agitator 6, for example, positioned above the agitator 6. The heating device 5 can be, for example, an electric heating device 5, used to heat the gaseous medium in the vulcanizing capsule 1, such as pressurized nitrogen. The agitator 6 can be, for example, a fan, an impeller, etc., driven by rotation to circulate the gaseous medium in the vulcanizing capsule 1, which helps to homogenize the temperature of the gaseous medium in the vulcanizing capsule 1.

[0042] The rotary drive device is preferably an electric motor. For example, the end of the rotating drum 19 furthest from the agitator 6 is driven by the electric motor. The rotating drum 19 is connected to the rotor of the electric motor, and the connection between the rotating drum 19 and the rotor can be direct or indirect. For example, the rotating drum 19 and the rotor are driven by a magnetic component, with non-contact magnetic components provided on both the rotor and the rotating drum 19, and the motor rotor drives the rotating drum 19 to rotate through magnetic force. And / or, the connection between the rotating drum 19 and the agitator 6 can be direct or indirect. For example, the rotating drum 19 and the agitator 6 are driven by a magnetic component, with non-contact magnetic components provided on both the agitator 6 and the rotating drum 19, and the rotating drum 19 drives the agitator 6 to rotate through magnetic force.

[0043] The heating device 5 includes a support assembly 7 and a heating element 8. The support assembly 7 is adapted to mount the heating element 8. The support assembly 7 is fixedly mounted on a ring seat 9, and a channel for the flow of gas medium is formed inside the support assembly 7. A cable conduit 10 is also provided between the support assembly 7 and the ring seat 9. A cable hole 11 is opened on the ring seat 9, and the cable hole 11 preferably communicates with the inner hole of the cable conduit 10. The cable 12 passes through the cable hole 11 and the cable conduit 10 in sequence and connects to the heating element 8. The cable conduit 10 is located on the outer periphery of the stirring device 6. The cable conduit 10 can be fixedly mounted on the ring seat 9 and / or the support assembly 7. For example, both ends of the cable conduit 10 are connected to the cable hole 11 on the support assembly 7 and the ring seat 9, respectively. Multiple cable conduits 10 can be provided to connect multiple heating elements 8. For example, three, four, or five cable conduits 10 are provided, and multiple cable conduits 10 are arranged circumferentially on the outer periphery of the stirring device 6. By setting up the conduit 10, the cables 12 can be bundled and led out, avoiding interference between the rotation of the agitator 6, the contraction of the vulcanizing capsule 1, etc., and the cables 12. The cables 12 are more orderly and save space.

[0044] The support assembly 7 includes a support portion 13 and a mounting portion 14.

[0045] Preferably, the heating element 8 is an induction heating coil, and a heat insulation component 15 is provided between the induction heating coil and the heating cylinder to prevent damage to the induction heating coil. A heat dissipation component 16 is provided on the inner side of the heating cylinder. The induction heating coil induction heats the heating cylinder and / or the heat dissipation component 16, thereby transferring heat to the gas medium. The heat dissipation component 16 conducts heat from the heating cylinder, increasing the heat dissipation area and improving heating efficiency. The heat dissipation component 16 includes a plurality of fins spaced apart circumferentially, the fins being connected to the inner wall of the heating cylinder and extending radially.

[0046] A protective component 17 is provided on the outer side of the heating component 8 to prevent the vulcanizing capsule 1 from coming into contact with the heating device 5 and causing damage to the vulcanizing capsule 1 or the heating device 5. The protective component 17 can be located on the outer periphery of the heating component 8, specifically in the form of a protective cover. The protective cover is fixedly installed on the mounting part 14 or the ring seat 9.

[0047] During the vulcanization process, the tire is loaded onto the vulcanizing bladder 1 from the outside, and then the vulcanization mold is closed, thus clamping the tire in the vulcanization space between the vulcanizing bladder 1 and the vulcanization mold. Pressurized nitrogen gas is injected into the enclosed space inside the vulcanizing bladder 1 through a first gas channel and heated by a heating device 5. This heated and pressurized nitrogen gas heats and pressurizes the tire from the inside through the vulcanizing bladder 1, while the mold heats and pressurizes the tire from the outside.
