[0012] 1. Compared with the prior art, this accelerated curing device for thermoplastic acrylic resin coatings, by setting up a compression spring, a slider, and a limiting frame, allows the placement rack to be pushed into the curing chamber during disassembly and cleaning. The placement rack drives the limiting rod to push the slider, and the slider compresses the compression spring as it moves, thereby separating the limiting block from the limiting frame. Then, the placement rack is rotated downwards, and under the push of the reaction force of the compression spring, the slider pushes the limiting rod to slide outwards from the fixed frame, thus allowing the placement rack to be pulled out of the curing chamber for cleaning. This improves the convenience of disassembling the placement rack.

[0013] 2. Compared with the prior art, the accelerated curing device for thermoplastic acrylic resin coatings, by setting up a first purification filter plate, a second purification filter plate, and a circulation pipe, uses a second fan to draw cold air into the heating box for heating during use, and then delivers it into the air box through the connecting pipe. The hot air is then sent into the curing box by the first fan to heat and cure the objects placed on the rack. The exhaust gas generated during curing is discharged into the purification box by a third fan, purified by the first and second purification filter plates, and then enters the circulation pipe. It is then drawn into the heating box by the second fan for transportation. This allows for air circulation and purification, avoiding air pollution caused by exhaust gas discharge.
