Description

Technical Field

[0001] The invention relates to the field of ceramic body loading and unloading equipment, and in particular to a kiln outer rail automatic loading and unloading equipment and method. Background Art

[0002] At present, the embryos of ceramics fired in kilns are manually transported out of the kiln. The embryos are transported from the kiln car to the glazing station for glazing. After glazing, they are manually transported to the kiln car and put into the kiln for high-temperature sintering. In order to save time in the process, the kiln is usually set close to the track and the glazing station. The high temperature of the furnace wall still makes it difficult for workers to work and poses a safety hazard. In order to maximize the thermal efficiency of the kiln, the kiln car is generally set up in multiple layers. Repeated handling by workers in a high-temperature environment can easily cause damage to the embryos. The multi-layer setting of the kiln car causes the embryos to be closely arranged with small gaps between each other, which can easily lead to unsatisfactory quality due to uneven heating in the kiln.

Driven by the movement of the chain, the movable slider (22) moves perpendicularly to the direction of the auxiliary beam (5) so that the manipulator (2) can perform fine adjustment. A chain is provided on the upper part of the auxiliary beam (5) for moving the cross beam (4) on the auxiliary beam (5). The crawler frame (7) is annular and has an electric wire built therein, one end of which is embedded and connected with a groove (8). When the cross beam (4) moves on the auxiliary beam (5), the crawler frame (7) enters the groove (8) accordingly. The groove (8) is connected to the auxiliary beam (5) by a plurality of connecting blocks (81).

[0027] Specifically, there are four support columns (3), which are provided at the front and rear ends of two auxiliary beams (5). The number of support columns (3) can be appropriately increased according to the length of the auxiliary beams (5) to ensure the stability of the auxiliary beams (5).
