AI Technical Summary

Technical Problem

The capsules of existing all-steel hot plate tire vulcanizers are prone to uneven shapes when vacuum shrinks, resulting in uneven flap separation and increasing the risk of early damage to the capsule.

Method used

A vulcanizer automatic molding and adjustment device is designed. By installing a linear sensor in the central mechanism cylinder and connecting it with the PLC controller, the capsule is fully automatic and evenly divided. When the capsule rises to a specific height, the device automatically fills with nitrogen to shape to ensure even flap separation of the capsule.

Benefits of technology

The automatic shaping of the capsule is achieved throughout the process, ensuring even flap separation of the capsule and reducing the risk of early damage to the capsule.

Description

Technical Field

[0001] The utility model relates to the field of tire vulcanizing devices, in particular to an automatic shaping and adjusting device for a mold opening bladder of a vulcanizing machine. Background Art

[0002] As we all know, the all-steel hot plate tire vulcanizer is the mainstream type of tire vulcanizing equipment at present. The capsules used in the machine are larger than those used in semi-steel ones. This makes it very easy for the capsules to produce various shapes when they rise from a vacuum-shrinking state. Whether the capsules that shrink after vacuuming are evenly divided depends on the random vacuuming state. After the center mechanism rises, the capsules with uneven petals are easily scratched when the tire unloader turns to unload the tire. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an automatic shaping and adjusting device for a mold opening bladder of a vulcanizing machine, which realizes full-automatic and uniform petal separation of the bladder and reduces early damage of the bladder.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an automatic shaping and adjusting device for a mold opening capsule of a vulcanizer, which is provided with a vulcanizer base and is characterized in that a central mechanism oil cylinder is installed below the vulcanizer base, a cylinder rod of the central mechanism oil cylinder passes through the vulcanizer base, a capsule clamp is installed at the end of the cylinder rod, a capsule is sealed and installed between the capsule clamp and the vulcanizer base, a central mechanism linear sensor is installed in the central mechanism oil cylinder, the central mechanism linear sensor is connected to the input end of a PLC controller, and the action of the central mechanism oil cylinder is controlled by the PLC controller.

[0005] The utility model has the beneficial effect that the whole process of opening the mold capsule can be automatically finalized, so as to realize automatic and uniform petal separation of the capsule and reduce early damage to the capsule. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0007] Figure 1 A schematic structural diagram of the utility model.

[0008] In the figure, 1. capsule fixture, 2. vulcanizer base, 3. center mechanism cylinder, 4. center mechanism linear sensor, 5. capsule shaping height, 6. capsule stretching height, 7. capsule. DETAILED DESCRIPTION

[0009] In the figure, the utility model is provided with a vulcanizer base 2, a central mechanism oil cylinder 3 is installed under the vulcanizer base 2, a cylinder rod of the central mechanism oil cylinder 3 passes through the vulcanizer base 2, a capsule fixture 1 is installed at the end of the cylinder rod, a capsule 7 is sealed and installed between the capsule fixture 1 and the vulcanizer base 2, a central mechanism linear sensor 4 is installed in the central mechanism oil cylinder 3, the central mechanism linear sensor 4 is connected to the input end of the PLC controller, and the action of the central mechanism oil cylinder 3 is controlled by the PLC controller.

[0010] At the end of vulcanization, the mold will automatically open, and the capsule 7 fixed by the capsule fixture 1 will rise simultaneously with the rise of the cylinder rod of the central mechanism oil cylinder 3. At this time, the capsule 7 is in a vacuum state. When the capsule 7 rises to Figure 1 When the capsule is at the capsule shaping height 5, the PLC controller turns on the capsule shaping signal, and the capsule shaping time timer starts counting for 3 seconds. At this time, the capsule 7 will be filled with nitrogen for 3 seconds. After 3 seconds, the nitrogen filling action will be cut off. At this point, the automatic shaping action of the capsule 7 is completed. The capsule 7 will change from the uneven petals that rise directly by vacuum to the uniform petals after automatic shaping, and then automatically rise to Figure 1 The capsule stretching height is set to 6 positions, and the entire mold opening capsule automatic adjustment function is completed.
