Description

Technical Field

[0001] This utility model relates to the field of hot stamping printing technology, and in particular to a hot stamping device with an arc-shaped hot stamping head structure. Background Technology

[0002] With the continuous development of industrial technology, printing processes have also undergone significant changes. Currently, relatively mature technologies include screen printing and hot stamping. However, for hot stamping, traditional techniques are limited to flatbed hot stamping. This involves attaching a pre-etched silicone plate to an aluminum block and then fixing it to a heating plate with screws. This technique is only suitable for hot stamping the sides of cylindrical products. As the product rotates, the hot stamping plate and the product are constantly in tangential motion. If this flatbed hot stamping technique is used for hot stamping the top of a bottle cap, because the top of the bottle cap is flat, the actual printing effect differs greatly from the intended effect. The hot stamping plate presses onto the product through the hot stamping foil, creating a micro-gap between it and the cap surface. This gap traps air, which cannot escape, resulting in air bubbles and an unsatisfactory hot stamping effect. Currently, there is no solution to this problem on the market. Utility Model Content

[0026] In this embodiment, the boss 70 is cylindrical and its vertical axis passes perpendicularly through the swing axis of the heating plate 10 to ensure that the swing trajectory of the hot stamping arc convex surface 71 passes through its axis, thus ensuring the accuracy of the hot stamping position.
