Description

Technical Field

[0001] The utility model relates to the technical field of carton production, and particularly relates to an automatic cardboard bonding device for carton production. Background Technique

[0002] Cartons are widely used packaging products with various specifications and models, mainly made of different kinds of papers bonded together by adhesives. According to the materials used, cartons are mainly divided into corrugated cartons and single-layer cardboard boxes, etc. Among them, corrugated cartons have become the most common type of cartons due to their good compressive and buffering properties. In addition, there are various types of cartons such as folding boxes, gift boxes, document boxes, display boxes, food boxes, wine boxes, etc. to meet the needs of different fields.

[0003] In the process of carton production, the existing automatic cardboard bonding device for carton production usually uses a glue spraying component to spray glue onto the surface of the cardboard, and then bonds multiple layers of cardboard to improve the compressive and buffering properties of the carton. Since the glue spraying component is relatively close to the cardboard and the spraying range is limited, the glue is concentrated on the surface of the cardboard, resulting in uneven distribution of the glue, which in turn affects the bonding effect of the cardboard. Moreover, after long-term use of the glue spraying component, the glue may block the spray pipe, resulting in the glue being unable to evenly cover the cardboard and affecting the bonding effect. Therefore, we propose an automatic cardboard bonding device for carton production to solve the problems mentioned above. Summary of the Utility Model
