Description

Technical Field

[0001] This utility model relates to the field of paper mounting machine technology, and in particular to a paper mounting machine with an automatic paper feeding unit. Background Technology

[0002] The laminating machine is a key piece of equipment in cardboard box production. Its core function is to precisely bond the face paper and corrugated paper to form a cardboard box base material with a certain strength and aesthetic appeal. Existing laminating machines mostly use a manual paper feeding method, where operators place the face paper individually or in stacks at the feeding station, and the subsequent mechanism of the equipment completes the conveying and bonding. However, existing technology has the following drawbacks: low paper feeding efficiency; poor positioning accuracy: when manually placing paper, problems such as paper misalignment and skewing are prone to occur, resulting in a bonding deviation between the face paper and corrugated paper exceeding 0.5mm, which does not meet the precision requirements of cardboard box processing; high risk of paper damage: when handling paper manually, it is easy for paper wrinkles and edge damage due to hand stains, friction, or collisions, especially for thin face paper, where the damage rate can reach over 5%; high labor costs: a single laminating machine requires at least one dedicated paper feeding operator, and under long-term operation, labor costs account for more than 40% of the equipment operating costs. Therefore, a laminating machine with an automatic paper feeding unit is needed. Utility Model Content
