Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping bottom film relief preheating devices, in particular to a bottom film relief preheating device for three-dimensional hot stamping of packaging boxes. Background Technique

[0002] For the three-dimensional hot stamping of the hot stamping bottom film relief preheating device, a hot stamping machine with high precision must be selected. Since this process requires two templates, a concave template and a convex template, once the machine precision is insufficient, the convex die will be damaged. When using a flat-bed cylinder hot stamping machine for hot stamping, the thickness of the convex die should be reduced, and the concave and convex depths of the concave and convex dies should also be reduced, so that the effect is better. For the concave and convex templates, the main adjustment during installation is to make the concave and convex patterns on the concave and convex templates coincide with the positions of the printed patterns. Generally, a thin rubber sheet can be used to replace the convex die first, and then the convex die can be installed after the concave and convex positions are adjusted, which is more convenient for adjustment.

[0003] In the existing hot stamping bottom film relief preheating device, a thermostat is used for preheating. When the three-dimensional hot stamping of the packaging box is preheated by conveying, a mobile hot air generator is used, and the hot air is easily conveyed to other three-dimensional packaging boxes, resulting in uneven temperature control and making it difficult to perform centralized preheating treatment.
