[0002] Partition boards are the main material for non-load-bearing internal partitions in general industrial buildings, residential buildings, and public construction projects, and pipe drawing of partition boards is an indispensable part of the production process of partition boards. Currently, most of the pipe drawing of partition boards is still mainly done manually, with low work efficiency and high labor intensity.

[0003] Prefabricated lightweight wall panels include processes such as mold placement, molding, curing, tube pulling and demoulding. Since the molds usually need to be reused, the entire production line is a closed-loop structure. At the same time, the curing process takes a long time and usually requires multiple layers to be placed with multiple molds set side by side on each layer.

The front and rear of the curing kiln are respectively provided with a front lifting structure and a rear lifting structure. There are multiple layers of conveying structures arranged side by side in the curing kiln, and each layer of conveying structure is composed of N curing conveying slide rails arranged side by side on the left and right. The front lifting structure and the rear lifting structure are respectively provided with N front lifting conveying slide rails and N rear lifting conveying slide rails that can be connected one by one with the front end and the rear end of the curing conveying slide rail. The N front lifting conveying slide rails are arranged side by side on the left and right and can move up and down, and the N rear lifting conveying slide rails are arranged side by side on the left and right and can move up and down.

[0005] When the applicant used the aforementioned production line to prepare prefabricated wall panels, it was found that there was generally only one preparation slide rail, while the front lifting structure and the rear lifting structure had N slide rails.
