[0002] The conventional hot stamping machine, the hot stamping plate is placed on the gold stamping plate, and the anodized aluminum foil contacts the hot stamping plate and the printing material under the action of compression. The hot stamping plate has a certain amount of heat due to the heating of the hot plate. The heat-meltable dyeing resin layer and the adhesive melt due to the heating of the anodized aluminum foil. The adhesion of the dyeing resin layer decreases, while the adhesion of the special heat-sensitive adhesive increases after melting. The aluminum layer is peeled off from the anodized aluminum film and transferred to the printing material. With the removal of pressure, the adhesive cools and solidifies rapidly, and the aluminum layer is firmly attached to the printing material to complete the hot stamping process.

[0003] The existing hot stamping machine also has a conveying mechanism inside for conveying hot stamping paper. For example, the hot stamping machine conveying mechanism disclosed in the Chinese utility model patent with the authorization announcement number CN216471242U includes a rack. Two support uprights are provided inside the rack support. A paper feeding channel and a paper collecting channel are provided between the two support uprights. Each channel has a pressure roller and a guide rod that are relatively matched and reversed to form. The support uprights have a support seat between them. A left-right direction through gap is provided on the support uprights. A horizontally extending reversing lever is connected to the support seat. One end of the reversing lever is connected to the support seat, and the other end gradually inclines towards the gap direction from front to back. This allows the hot stamping paper to bypass the reversing lever and be output to the outside through the gap. A paper roller is also provided between the support uprights. It is used to feed the hot stamping paper through the paper feeding channel into the hot stamping machine, and after working inside the hot stamping machine, it is collected through the paper collecting channel. After recycling, it enters the paper collecting machine through the gap to complete the paper collecting work.

[0004] The existing paper roller is generally connected between the two support uprights in a quick-release manner. Coaxial support shafts are arranged on the two support uprights, respectively.
