Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper box production, in particular to a glue spraying device for corrugated paper box production. Background Art

[0002] Corrugated boxes are a type of packaging container made by laminating formed core paper and boxboard to form corrugated cardboard, which is then processed through printing, cutting, and nailing. The shape of the corrugations is like small arches. This structure allows the cardboard to have good cushioning properties while maintaining a certain rigidity. It can effectively absorb external impact and protect the items packaged inside. Common corrugated shapes include U-shape, V-shape, UV-shape, etc. Corrugations of different shapes will vary in cushioning performance, compressive strength, etc. The glue spraying equipment for corrugated box production is one of the key equipment in the corrugated box manufacturing process. It is mainly used to evenly spray glue on specific parts of the corrugated cardboard to achieve bonding and forming of the cardboard.

[0003] The prior art, such as the utility model with publication number CN221392496U, relates to the technical field of glue spraying equipment. The utility model discloses a glue spraying equipment for corrugated cardboard processing, including a glue spraying machine body, a transverse track, a longitudinal track and a glue spraying head. The top surface of the glue spraying machine body is provided with a transverse track, and the top surface of the transverse track is connected to the longitudinal track. The glue spraying head is provided at the side end of the longitudinal track. A positioning pad is fixed on the top surface of the glue spraying machine body below the glue spraying head. The utility model uses an adsorption-type limiting structure to place the glue on the straight plate when the straight plate is placed on the straight plate. After the positioning pad is placed, a negative pressure is formed in the air outlet through the bellows, so that the cardboard can be adhered and fixed on the surface of the positioning pad, solving the problem of the inconvenience of fixing the cardboard when spraying glue in the existing corrugated cardboard processing spraying equipment, greatly improving the stability of the cardboard when spraying glue in the corrugated cardboard processing spraying equipment, thereby improving the accuracy of cardboard spraying, and solving the problem that when gluing, due to the light weight of the carton, it is easy to move with the glue spray head, affecting the accuracy of glue spraying, and tight fixation easily leads to indentations on the cardboard surface, affecting the aesthetics.

[0004] In daily work, it is found that when the existing glue spraying equipment used in corrugated cardboard production is in use, a glue spray head usually has only one size of glue discharge diameter. During the production process, it is not convenient to adjust according to the gluing requirements of different corrugated cardboard boxes. It is easy to apply too much or too little glue, thus affecting the quality. At the same time, the glue spray head cannot be covered after use, and it is easy for impurities to enter and cause blockage, affecting use, which leads to the problem that the existing glue spraying equipment is not convenient to adjust the diameter and protect.
