Description

Technical Field

[0001] The utility model relates to the technical field of hot bending kilns, and in particular to an oblique-opening rock slab hot bending kiln. Background Art

[0002] The rock slab hot bending kiln mainly uses high temperature to soften the rock slab, and then uses a mold to process the rock slab into a specific shape, such as a concave wash basin, and then naturally cools and hardens. The temperature in the kiln is about 1200 degrees Celsius when working, and it takes 4-5 hours to heat. Due to the high temperature, the processed rock slab cannot be taken out of the kiln immediately, otherwise it will cool rapidly and crack, and needs to be placed in the kiln to slowly cool for 4-5 hours.

[0003] Generally, a smoke exhaust port is set above the kiln body to better assist the kiln in exhausting smoke and cooling, thereby ensuring the production efficiency of products in the kiln. However, the covers set above the existing smoke exhaust ports are mostly manual structures, which require people to open them one by one by hand, increasing the operator's workload and not conducive to the efficient production of rock slabs. Therefore, it is urgent to design an oblique-opening rock slab hot bending kiln to solve the above problems. Utility Model Content

[0022] The utility model provides an inclined-opening rock slab hot-bending kiln, which adopts a driving component 4, which drives the movement of the telescopic rod 44 through a power source 43, and converts it into a rotational movement of the cover plate 3 along the support member, thereby realizing rapid opening and closing of the cover plate 3.
