According to a plastic bottle cap laminating device proposed by patent authorization announcement number: CN118219482B, the invention drives the tray to rotate by a motor, and drives the multiple lower pressing plates on the top to rotate by the tray, thereby realizing the switching of the multiple lower pressing plates, and heating the multiple heating rings by the heater. At the same time, the hydraulic cylinder pushes the upper pressing plate to move downward, thereby realizing the compression molding of the plastic bottle caps. This design can facilitate the operator to load the materials into the remaining lower pressing plates during the compression molding process, thereby realizing rapid cycle processing and improving processing efficiency.

However, the mold barrel is installed on the electric heating plate, which makes it difficult to apply the release agent, resulting in uneven application of the release agent and affecting demolding. Therefore, there is a need to improve the prior art. Summary of the Invention
