Description

Technical Field

[0001] The utility model relates to the field of tire production, in particular to a tire vulcanization device. Background Art

[0002] Tires are usually made of wear-resistant rubber materials and installed on metal rims to support the vehicle body, buffer external impacts, achieve contact with the road surface, and ensure the driving performance of the vehicle. Tires are an important part of vehicle driving and directly affect the driving performance and safety of the vehicle. When producing tires, carbon black, natural / synthetic rubber, oil, additives, accelerators and other raw materials must be mixed according to the formula, and processed into semi-finished products of different sizes and shapes through processes such as extrusion and calendering. Subsequently, on the molding machine, composite parts, cords, belt layers, wrapping cloth and other semi-finished products are processed into green tires, and then the green tires are loaded into the vulcanization equipment and vulcanized through the mold under appropriate time and temperature conditions, such as vulcanization equipment with publication numbers CN215921051U and CN216400627U.

[0003] During the vulcanization process, the linear polymers in the rubber undergo a cross-linking reaction to form a network of polymer materials. This structural change significantly improves the tire's load-bearing performance, traction performance, cushioning performance, wear resistance and flexibility resistance, and gives it the appearance, pattern, font and tread pattern of a finished tire.

[0004] With respect to the above-mentioned related technologies, the inventors found that the temperature of the tire after vulcanization and demolding is usually higher than 80 degrees Celsius. In order to improve the shape stability and structural strength of the tire, the tire is generally taken out and placed in the corresponding area for cooling for a period of time. The conventional operation method is generally that the staff uses corresponding hooks and corresponding tools to take out the tire. However, since the surface temperature of the tire is too high and the temperature of the inner side of the tire cools down slowly due to the influence of the vulcanization capsule, manual removal of tire components is prone to burns and is dangerous, and it will also affect the tire unloading efficiency. Utility Model Content

[0005] The utility model mainly solves the technical problem of providing a tire vulcanization device, which improves the tire unloading efficiency and prevents the workers from being scalded.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a tire vulcanization equipment, which includes: a mounting frame and a lower heating mold connected to the inner bottom thereof, an upper heating mold is arranged on the top of the inner side of the mounting frame, a telescopic rod assembly for driving the upper heating mold to move up and down is connected to the top of the mounting frame, a tire unloading assembly is arranged between the upper heating mold and the lower heating mold, and a linear driving mechanism for driving the tire unloading assembly to move up and down is installed on one side of the front of the mounting frame;

[0007] The tire unloading assembly includes an annular frame and a swing arm member that drives the annular frame to swing left and right. After the swing arm member drives the annular frame to swing toward the inside of the mounting frame, the center of the annular frame and the center of the lower heating mold are on the same axis. An annular groove is provided at the bottom of the annular frame, and a plurality of gripping members are provided in the annular groove. The annular groove also includes a driving mechanism that drives the gripping members to move toward or away from the center of the annular frame at the same time.

[0008] By adopting the above technical scheme, the lower heating mold and the upper heating mold vulcanize the green tire, and the swing arm is driven to move to a suitable position under the action of the linear drive mechanism to match the position of the tire after the mold is opened, and the annular frame is driven to swing toward the inside of the mounting frame by the swing arm, so that the annular frame cover is arranged above the vulcanization capsule of the lower heating mold, and the driving mechanism gripper is moved, and the gripper is moved to the inside of the tire for clamping in cooperation with the linear drive mechanism, thereby realizing automatic unloading.

[0009] In a preferred example, the utility model can be further configured as follows: the driving mechanism includes a threaded rod and a slewing bearing connected to the inner top wall of the annular groove, the bottom of the slewing bearing is connected to an annular spiral bevel gear, the two ends of the threaded rod are respectively rotatably connected to mounting seats, the mounting seats are respectively connected to the inner walls of the annular groove, one end of the threaded rod is connected to spiral bevel gear 1, and the spiral bevel gear 1 is meshed with the annular spiral bevel gear, the clamping piece is passed through the threaded rod and threadedly connected to it, the outer side of the annular frame is connected to servo motor 1, one end of the servo motor 1 extends into the annular groove and is connected to spiral bevel gear 2, the spiral bevel gear 2 is meshed with the annular spiral bevel gear, the top of the annular groove is connected to a limit frame matching the clamping piece, and the top of the clamping piece is located in the limit frame.

[0010] By adopting the above technical solution, servo motor 1 drives spiral bevel gear 2, thereby rotating the annular spiral bevel gear and synchronously driving the corresponding spiral bevel gear 1 to rotate. At this time, spiral bevel gear 1 drives the threaded rod to move, so that the clamping member moves toward the center of the annular frame in the limit frame to adapt to the inner circle of the tire, and under the action of the linear drive mechanism, drives the clamping claw member downward to clamp the inner side of the tire, thereby improving the tire unloading efficiency.

[0011] In a preferred example, the utility model can be further configured as follows: the gripping member includes an L-shaped arm claw, the bottom end of the L-shaped arm claw is connected to an arc-shaped anti-slip bearing block, and the arc-shaped anti-slip bearing block is arranged toward the outer circumferential surface of the annular frame.

[0012] By adopting the above technical solution, after the L-shaped arm claw shrinks toward the center of the ring frame in cooperation with the driving mechanism, it cooperates with the linear driving mechanism to move downward, moves to the inside of the tire, and expands outward, so that the arc-shaped anti-slip bearing block is limited to the inside of the tire, and the tire is unloaded through the linear driving mechanism and the swing arm part, avoiding direct contact between workers and high-temperature tires, thereby reducing the risk of burns.

[0014] By adopting the above technical solution, servo motor 2 drives the rotating shaft to rotate, causing the support arm to swing left and right, so as to separate the tire from between the lower heating mold and the upper heating mold by swinging. This process is faster and more efficient than the traditional manual tire unloading method.

[0015] In a preferred example, the utility model can be further configured as follows: the telescopic rod assembly includes a hydraulic cylinder and two guide rods, and the bottom ends of the hydraulic cylinder and the guide rods are respectively connected to the upper heating mold.

[0016] By adopting the above technical solution, the hydraulic cylinder drives the upper heating mold to move downward and engage with the lower heating mold, thereby vulcanizing the green tire. At the same time, the guide rod moves synchronously and telescopically to improve the stability of the upper heating mold.

[0017] In a preferred example, the utility model can be further configured as follows: at least two guide rails are respectively connected to both sides of the mounting frame, and sliders are respectively slidably connected to the guide rails, and the sliders are respectively connected to the upper heating mold.

[0018] By adopting the above technical solution, the guide rail serves as a fixed path to ensure that the upper heating mold moves accurately in the vertical direction. At the same time, the movement of the slider on the guide rail enables the upper heating mold to move along a predetermined track to avoid deviation or shaking, thereby ensuring that the upper heating mold and the lower heating mold are engaged.

[0019] In summary, the utility model includes at least one of the following beneficial technical effects of a tire vulcanization device:

[0021] 2. The servo motor 1 drives the spiral bevel gear 2, thereby rotating the annular spiral bevel gear and synchronously driving the corresponding spiral bevel gear 1 to rotate. At this time, the spiral bevel gear 1 drives the threaded rod to move, so that the clamping piece moves toward the center of the annular frame in the limit frame to adapt to the inner circle of the tire, and under the action of the linear drive mechanism, drives the clamping claw piece downward to clamp the inner side of the tire, thereby improving the tire unloading efficiency.
