Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically to a mechanical booster device for a capsule-shaped drum. Background Technology

[0002] In the tire forming process, the bladder-type fully inverted forming drum is one of the key pieces of equipment. Its main function is to achieve the inverted forming of the tire carcass through the expansion and contraction of the bladder. During the inverted forming process, a certain amount of thrust needs to be applied to the bladder to ensure the quality and efficiency of the inverted forming process.

[0003] In the capsule manufacturing industry, the efficient operation of the capsule encapsulation drum relies heavily on the precise coordination of a mechanical booster device. This device plays a crucial role in providing stable power to the drum and ensuring the continuity of the capsule forming process. Currently, the mechanical boosters used in the industry generally rely on two traditional structures for their movement drive: one converts the rotational motion of a lead screw into linear movement, using the meshing transmission between the lead screw and nut to achieve position adjustment. While this method can guarantee transmission accuracy to a certain extent, it lacks effective buffering and adjustment capabilities when there are frequent starts and stops or slight changes in load, and is prone to impact vibration due to rigid transmission; the other method relies on the extension and retraction of a cylinder to propel the device. While pneumatic cylinder drives offer advantages such as fast response and relatively simple structure, their output force is significantly affected by fluctuations in air source pressure. Furthermore, a smooth transition at the end of the stroke when engaging with the forming drum is difficult to achieve. More importantly, this design flaw directly leads to a lack of stability in actual operation. The absence of a buffer structure makes the device prone to hard collisions with the forming drum or surrounding components during startup, shutdown, or switching of operating states. This not only exacerbates mechanical wear and shortens the overall lifespan of the equipment but may also cause deviations in the forming drum's operating posture, leading to quality problems such as uneven capsule preform wall thickness and incomplete sealing, thus failing to meet current requirements.
