Description

Technical Field

[0001] The invention relates to the technical field of tire molding and connection, in particular to a tire vulcanizer. Background Art

[0002] With the continuous development of the tire manufacturing industry, tire vulcanizers, as key equipment, play a vital role in the tire production process. In recent years, tire vulcanizer technology has made significant progress, gradually shifting from traditional vulcanization processes to more intelligent and automated production methods. Existing tire vulcanizers usually use advanced control systems and precise heating and pressure control technologies to ensure the quality and performance of tires during the vulcanization process.

[0003] In the tire production process, the tire vulcanizer is mainly used to plastically connect the various parts of the tire. During the vulcanization process, the various components of the tire, such as the tread, sidewall and carcass, are placed in the mold of the vulcanizer. Subsequently, by heating and applying pressure, these parts undergo plastic deformation and chemical reaction under the action of the vulcanizer, thereby achieving a firm connection. This process is crucial to ensure the overall performance and safety of the tire. Existing technologies achieve efficient and high-quality production of tires through precise temperature control and pressure regulation, as well as advanced vulcanization processes.

[0004] However, although the existing tire vulcanizer technology is relatively mature, there are still the following technical pain points. First, the precise control of temperature and pressure during the vulcanization process is still a challenge. Any slight deviation may affect the quality and performance of the tire. When the tire is vulcanized, the tire needs to be placed in the tire vulcanizer, and then the tire is squeezed and fixed downwards through the fixing device on the top of the tire vulcanizer, and then the tire is vulcanized. Since the tire vulcanization process is carried out in a high temperature environment, the tire vulcanizer will be squeezed from high to low for a long time, causing the main body of the tire vulcanizer to be slightly deformed, which causes the tire vulcanizer to have a quality impact on the vulcanization molding of the tire. Summary of the invention

[0005] The object of the present invention is to provide a tire vulcanizer to solve the problem that since the tire vulcanization process is carried out in a high temperature environment, the tire vulcanizer will be slightly deformed during the long-term extrusion from high to low, thereby causing the tire vulcanizer to affect the quality of the vulcanization molding of the tire.

[0049] The present invention solves the problem of slight deformation that may occur in a tire vulcanizer under high temperature and long-term extrusion conditions through the following technical solutions, thereby ensuring the quality of tire vulcanization molding:

[0050] Horizontal comparison device 4 and early warning system: A vulcanizer base 3 is installed at the bottom of the tire vulcanizer frame 1, and a horizontal comparison device 4 is set on the side wall of the base, and a camera 5 is used to capture the image between the top of the vulcanizer base.

[0051] The control device evaluates the horizontal relationship between the horizontal comparison device and the top of the base based on the camera data. When the angle deviation exceeds the preset value, an early warning will be triggered to alert the operator.

[0052] The vulcanizer base is equipped with a rigid fixing frame made of high-strength rigid material, including a fixing ring and a fixing plug, which is used to enhance the stability of the base and prevent deformation.

[0053] Modular vulcanizer base design: The vulcanizer base 3 is composed of a first vulcanizer base 301, a second vulcanizer base 302, a third vulcanizer base 303 and a fourth vulcanizer base 304 modules, which are interconnected to form a whole, and each module is equipped with a hydraulic lifting device 8 at the bottom to ensure stability and levelness.

[0054] A cover plate is arranged on the top of the hydraulic lifting device, and a slot is arranged between the cover plate and the side wall of the base, which matches with the insert block of the rigid fixing frame to further strengthen the base structure.

[0055] Real-time monitoring mechanism: Real-time monitoring is achieved with the help of cameras and control devices to promptly detect and respond to deformation trends and ensure the stability and quality of the vulcanization process.

[0056] The present invention effectively solves the deformation problem that may occur when the tire vulcanizer works at high temperature for a long time, and significantly improves the quality and stability of tire vulcanization molding.

[0057] The present invention increases the rigidity of the device base and has a modular design. When the tire vulcanizer is squeezed, the rigid ring and the plug are supported by a hydraulic support device to prevent the tire vulcanizer from being deformed. Even if it is deformed, only the base at the damaged position can be replaced according to the damage situation to avoid the waste of overall replacement. The prior art adopts an overall design, which is very difficult to repair once deformation occurs and has a high replacement cost.
