The receiving pan receives the demoulding agent dripping from the roller assembly 12, and the collecting port corresponds to the oil collecting barrel 62. The demoulding agent after collection can be filtered to remove impurities and recycled.

[0042] In summary, through the coating structure 1, the moving structure 2 and the sensing structure 3, the first roller 121 and the second roller 122 are sequentially lowered to contact the curing trough side plate 4 when the curing trough side plate 4 reaches the corresponding position, and rolling coating is performed, thereby realizing automatic coating of the edge of the curing trough side plate 4 and the set coating area, thereby improving production efficiency, ensuring the smooth progress of the demolding process, and saving labor costs.
