Description

Technical Field

[0001] The invention relates to the field of coal conveyor belt maintenance, in particular to a small-sized coal conveyor belt hot vulcanization device. Background Art

[0002] In the maintenance of coal conveyor belts, damage often occurs over long periods of operation due to factors such as impact from coal, wear, and aging. Hot vulcanization repair is a common repair method, but existing hot vulcanization equipment and processes for coal conveyor belts present numerous challenges. Traditional methods often rely on manual estimation using simple tools and lack precise measurement methods to accurately determine the size of the damaged area. This results in inappropriately sized repair rubber blocks, compromising repair quality and making the repaired belt susceptible to recurring problems during operation, such as localized cracking and detachment, which reduces the overall strength and service life of the belt. After the repair is completed, existing technologies often rely on manual cutting of excess rubber at the belt edges, a method that is not only inefficient but also difficult to ensure precise and smooth cutting. Uneven belt edges can cause belt deviation during operation, exacerbating belt edge wear and potentially leading to serious problems such as belt tearing, impacting the stable operation of the entire coal conveyor system, increasing safety risks, and increasing equipment maintenance costs. Furthermore, the structural design of existing devices is limited, making installation and operation difficult, impacting maintenance efficiency.
