Description

Technical Field

[0001] The utility model relates to the technical field of easy-tear cover processing, in particular to an aluminum foil embossing device for an easy-tear cover. Background Art

[0002] The tear-off lid is used as the top cover for packaging containers for foods such as milk powder, coffee powder, and chocolate powder. During the production process, a tear-off lid mold is typically used to emboss a pattern on the aluminum foil of the tear-off lid. This not only makes the tear-off lid more aesthetically pleasing, but also increases the strength of the aluminum foil.

[0003] The existing easy-tear cover aluminum foil embossing device must ensure precise alignment of the embossing mold during the mold closing process to avoid damage to the easy-tear cover aluminum foil due to squeezing or mold collision. This not only makes the process more difficult, requiring precise adjustment of the mold position during installation, but also causes the easy-tear cover aluminum foil to become trapped in the mold after embossing, making removal unnecessary and difficult. To address these issues, the following solution is proposed. Utility Model Content

The upper end of the embossing module 9 is provided with a pattern protrusion 10. The staff can place the easy-tear cover to be embossed into the positioning cavity 8 for positioning, and then move it downward through the embossing soft block 6, and the embossing soft block 6 is fitted with the embossing module 9 to achieve the pattern on the pattern protrusion 10 Pressing the aluminum foil of the easy-tear cover, thereby completing the embossing work of the easy-tear cover.

[0023] The front and rear ends of the embossing base 1 are respectively provided with fixing screws 27, and the top ends of the fixing screws 27 are located in the embossing module 9. The fixing screws 27 can be used to fix and remove the embossing module 9, so that the embossing module 9 with different patterns can be replaced to print a variety of patterns on the easy-tear cover aluminum foil. A number of positioning slides 28 are provided on the mounting plate 3, and the lower ends of the positioning slides 28 are respectively fixedly connected to the upper end of the mounting seat 5. When the mounting seat 5 moves up and down, it can drive the positioning slides 28 to move up and down along the mounting plate 3, thereby making the movement trajectory of the embossing soft block 6 straighter and more stable, thereby improving the quality of the embossing.
