Description

Technical Field

[0001] The invention relates to the technical field of leather ball production and processing, and in particular to a vulcanization device and method for leather ball production and processing. Background Art

[0002] Vulcanization refers to the process in which rubber or silicone rubber materials react chemically with vulcanizing agents under certain temperature and pressure to transform the linear structure of the rubber materials into a three-dimensional structure. Vulcanization is a crucial process step in the production of leather balls. The vulcanization process cross-links the molecular structure of the rubber material through chemical reactions, thereby significantly improving its elasticity, wear resistance and weather resistance. This process not only determines the physical properties of the leather ball, but also directly affects its service life and safety. Modern vulcanization equipment usually ensures uniform vulcanization of the rubber by precisely controlling the temperature and pressure.

[0003] With the advancement of science and technology, the market's performance requirements for leather ball products are constantly increasing, and more efficient vulcanization equipment is urgently needed to meet the needs of large-scale production. In the current production and processing of leather balls, when the vulcanization equipment vulcanizes and bonds the inner liner and the outer rubber sheet, the operator needs to accurately position multiple rubber sheets inside the upper and lower sets of molds. This process is not only complicated, but also has a long operation cycle, which directly affects the overall production efficiency; in addition, after the inner liner and the outer rubber sheet are vulcanized, the operator needs to transfer the molded leather ball to the mold with a pattern to manufacture the pattern. This step further prolongs the operation cycle, increases labor costs and production time, and has an adverse effect on the production and processing of leather balls. Therefore, the present invention provides a vulcanization device and method for leather ball production and processing to solve the problems raised in the above background technology.
