Description

Technical Field

[0001] The utility model relates to the technical field of glue coating machines, and in particular to a four-sided glue coating machine. Background Art

[0002] The gluing machine is mainly composed of a frame, a gluing roller, and a transmission device. The glue is applied to the surface of the product by rotating the gluing roller. The most commonly used gluing machines include double-roller gluing machines, three-roller gluing machines, and four-roller gluing machines. During the gluing process, glue is generally applied to one surface or two opposite surfaces of the product. However, in the gluing work of some paper box products, since the cross-section of such products is a rectangular structure, glue needs to be applied to its four surfaces. The same product needs to be repeated for many times to complete the gluing work, which takes a long time in the production and processing process. Utility Model Content
