Description

Technical Field

[0001] This application relates to the field of tire vulcanization technology, and in particular to a fully automatic electrically heated multi-layer bladder vulcanizing machine. Background Technology

[0002] Tire vulcanization is a core process in tire manufacturing that determines the mechanical properties and appearance of the finished product. The uncrosslinked tire blank (green tire) assembled after the molding process is soft and has extremely low strength. It needs to be fed into the vulcanization chamber of a vulcanizing machine, where it undergoes shaping and vulcanization using a metal vulcanizing mold and an internal vulcanizing capsule. The process principle involves the vulcanizing agent within the rubber compound stimulating the rubber molecular chains to undergo a crosslinking reaction under high temperature and high pressure (170–190°C), constructing a stable three-dimensional network structure. This transforms the plastic raw rubber into a highly elastic, wear-resistant, and aging-resistant finished rubber. Simultaneously, the tread pattern and sidewall markings are pressed out using the grooves on the outer wall of the mold, completing the tire's shape shaping.

[0003] Existing tire vulcanizing equipment generally suffers from low integration. The horizontal layout of the equipment occupies a large area of ​​the factory, and the loading and unloading of green and finished tires rely on manual operation, resulting in a low overall level of automation. Therefore, how to achieve a vertically compact layout of multiple vulcanizing stations and complete the automatic loading and unloading of tires is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] This device provides a fully automatic electrically heated multi-layer capsule vulcanizing machine, the specific implementation method of which is as follows: Fully automatic electric heating multi-layer capsule vulcanizing machine, including: The tire storage rack and mounting rack have multiple vulcanization chambers. The vulcanization chambers are equipped with openable vulcanization molds. The left and right sides of the vulcanization chambers are open. The second lifting assembly and the first lifting assembly are respectively located on both sides of the opening of the vulcanization working chamber. Both are equipped with circumferential claws with a steering structure. The second lifting assembly is used to use the circumferential claws to send the green tire on the storage rack into the vulcanization mold for vulcanization. The first lifting assembly is used to use the circumferential claws to automatically remove the vulcanized tire from the vulcanization mold.

[0005] Based on the above technical solutions, existing vulcanizing machines mainly use hydraulic systems for the lifting and lowering of the mold. The lifting structure of this application is changed to a motor-controlled screw mechanical structure. Currently, most vulcanizing machines use hydraulic or pneumatic systems for force application. We use the precise torque control of a servo motor to convert it into lifting pressure, and ensure the smoothness of mold opening and closing through bearing clearance.

[0006] Preferably, the opening and closing direction of the vulcanizing mold is different from the opening direction of the vulcanizing working chamber.

[0007] Preferably, the mounting frame has multiple vulcanizing chambers arranged in parallel on each layer; each vulcanizing chamber on the same layer is equipped with an independent second lifting component and a first lifting component, which are diagonally distributed on both sides of the opening of the vulcanizing chamber.

[0008] Preferably, the accompanying drawings only show the second lifting assembly and the first lifting assembly equipped on one side of the vulcanizing working chamber on the same layer. The second lifting assembly and the first lifting assembly on the other side are not shown. The second lifting assembly and the first lifting assembly have the same structure. Taking the second lifting assembly as an example, it includes an electric screw and a lifting seat. The electric screw is used to drive the lifting seat to move vertically between the vulcanizing working chambers on each layer. The lifting seat is a double-layer structure for installing the first motor and the boom.

[0009] Preferably, the circumferential gripper includes a first motor, the output end of which is equipped with a boom. The distal end of the boom is equipped with a first electric push rod and a fixed ring. A rotating ring is provided on the fixed ring. The first electric push rod is used to drive the rotating ring to rotate. The fixed ring has several radially sliding grippers arranged along its circumference, and each gripper and the rotating ring are provided with a synchronous guide structure. The rotating ring drives each gripper to synchronously change diameter, thereby gripping and transferring the tire body. The rotating ring is rotatably located outside the fixed ring and has several arc-shaped guide grooves. The first electric push rod is connected to the eccentric end of the rotating ring. The fixed ring is slidably connected to the grippers through radial guide rails, and each gripper is also slidably connected to the arc-shaped guide grooves.

[0010] Based on the above technical solution, the circumferential chuck is driven entirely by motors and electric cylinders, without any air or hydraulic power source.

[0011] Preferably, the tire storage rack has multiple layers of tire storage cavities in a vertical direction, and each tire storage cavity is equipped with a locking component for positioning the green tire body; the tire storage cavity corresponds one-to-one with the vulcanization operation cavity, and the locking component is a vertical clamping part driven by a third screw structure.

[0012] Based on the above technical solutions, the tire storage rack and mounting frame do not adopt the currently popular column structure that is easy to disassemble and install. Instead, they maintain an integral frame structure. Furthermore, the frame structure is assembled into a mortise and tenon joint structure before manufacturing. Secondary welding is only carried out after the structure is assembled, ensuring that the equipment can maintain sufficient stability and strength even if there are no welds.

[0013] Preferably, each vulcanizing chamber is equipped with a coarse mold closing assembly and a fine mold closing assembly. The vulcanizing mold includes an upper mold and a lower mold that are vertically lifted and engaged. The coarse mold closing assembly is used to adjust the opening and closing distance of the vulcanizing mold with a large stroke, while the fine mold closing assembly is used to compact the opening and closing area with a small stroke. The coarse mold closing assembly has a fast speed, which increases the mold closing speed, while the fine mold closing assembly has a slow speed, which increases the mold closing force and tightness.

[0014] Preferably, the vulcanizing chamber is provided with a vertical guide rail, and the rough die assembly includes a lifting platform that is slidably connected to the vertical guide rail; the rough die assembly also includes a sixth lead screw structure driven by a second motor, and the output end of the sixth lead screw structure is connected to the lifting platform.

[0015] Preferably, the fine-clamping mold assembly includes a vertically arranged second lead screw structure, and the input end of the second lead screw structure is connected to a third motor.

[0016] Based on the above technical solutions, this application takes into account the characteristics of motorcycle tires and semi-steel and all-steel tires, and sets the number of vulcanization layers to two independent upper and lower vulcanization mechanisms. By utilizing the vertical space advantage, the equipment is made into an overlapping space with independent upper and lower parts, which not only ensures the independent operation of a single tire, but also increases the effective utilization of space and robotic arms.

[0017] In summary, this application includes the following beneficial technical effects: 1. This invention utilizes a mounting frame to vertically stack and integrate multiple vulcanization chambers, significantly reducing the floor space of the equipment. The automatic loading and unloading of the tire body before and after vulcanization is completed through circumferential claws, a first lifting component, and a second lifting component. Moreover, one set of transfer structure can be adapted to the vulcanization chambers of each layer simultaneously. 2. The present invention configures a tire storage chamber that is horizontally aligned with the vulcanization operation chamber. The tire storage rack adopts a V-shaped layout to adapt to the rotation path of the circumferential claws. The circumferential claws can enter the tire storage chamber for green tire removal by rotating. 3. The present invention has a simple structure. The locking component can ensure the stability of the green tire placed on the tire storage rack. The second lifting component, the circumferential claw and the locking component work together to control the locking component to unlock when the circumferential claw performs the tire retrieval action, so as to release the green tire to be grasped.
