Description

Technical Field

[0001] The utility model belongs to the field of packaging box production, and in particular relates to a patch variable-distance feeding tool. Background Art

[0002] When installing rivets on traditional packaging cardboard, the rivet holes are prone to damage, which affects the overall strength and quality of the packaging. For this reason, people have come up with the idea of ​​placing a lining strip with a metal patch inside the packaging box at the location where the holes need to be punched. However, the metal patching work on the existing lining strip is usually done manually, which is time-consuming and labor-intensive, with low production efficiency, low precision and high cost. When rivets need to be set on packaging boxes of different models or the rivet positions change, they need to be re-aligned and patched one by one, which is very inconvenient. For this reason, people hope to have a better and faster way to complete these tasks. Utility Model Content
