Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production and processing technology, specifically to a multi-layer corrugated cardboard production equipment. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper (commonly known as "corrugated sheet", "corrugated paper", "corrugated core", "corrugated base paper") and one layer of cardboard (also known as "boxboard" or "boxboard"). It has high mechanical strength and can withstand collisions and drops during handling. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and the cardboard, and the structure of the carton itself.

[0003] Corrugated cardboard has a multi-layered structure, so glue is needed between the layers for subsequent bonding. The glue rollers and pressure rollers in a typical glue applicator cannot be moved, so it can only process corrugated cardboard of a single thickness. If different sizes are needed, the glue rollers and pressure rollers need to be replaced, which reduces processing efficiency and increases usage costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multi-layer corrugated cardboard production equipment with a simple structure. It can change the position of the lower glue roller and the pressure roller according to the workpieces of different sizes and thicknesses to facilitate subsequent processing and has good performance.

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-layer corrugated cardboard production equipment, including a left support plate and a right support plate. A positioning roller and a moving roller are arranged between the left support plate and the right support plate. A pressure roller is arranged between the positioning roller and the moving roller. Lifting components are arranged on both sides of the pressure roller. A feeding guide roller is arranged at the bottom of the moving roller. A discharge guide roller is arranged at the top of the positioning roller. A main adjustment device and an auxiliary adjustment device are respectively arranged at both ends of the discharge guide roller.

[0006] Furthermore, a first motor for controlling the positioning rubber roller and a second motor for controlling the moving rubber roller are provided on the outer side of the right support plate.
