Description

Technical Field

[0001] The invention belongs to the technical field of printing equipment, and in particular relates to a printing equipment and a working method for an outer packaging box. Background Art

[0002] Outer packaging printing equipment is an indispensable key component in the modern packaging industry. It is mainly used to print patterns, texts, barcodes and other information on outer packaging materials to ensure that product information is accurately conveyed to consumers while enhancing the product's aesthetics and brand recognition. These equipment usually include flexographic printing machines, offset printing machines, screen printing machines and digital printing machines. Among them, flexographic printing is widely used in the field of flexible packaging due to its environmentally friendly characteristics and high-efficiency printing speed. Offset printing machines are suitable for high-quality image printing of rigid packaging such as paper boxes and cartons. Screen printing machines are particularly effective for products that require a thick ink layer or special effects. Digital printing machines are increasingly favored in the small-batch, multi-variety market environment for their high flexibility and personalized customization capabilities. These devices generally use computer control systems to achieve precise control in the automated production process, which can not only improve production efficiency but also ensure stable and reliable printing quality. In addition, with the advancement of technology, modern printing equipment also has the ability to produce online, which can be seamlessly connected with post-processing processes such as lamination, hot stamping, and die-cutting to form a complete production line to meet diverse needs. In general, outer packaging printing equipment is a high-tech product that combines multiple fields such as mechanical engineering, electronic technology and material science. Its development level directly affects the overall competitiveness of the packaging industry.

[0003] In the prior art, the outer packaging is usually in the form of cardboard before printing. Each outer packaging material is conveyed to the lower side of the printer through a conveying structure, and the printer is pressed down to contact the surface of the outer packaging material to print the pattern on the surface of the outer packaging material. When the outer packaging material is conveyed to the lower side of the printer, it is often conveyed by a conveying roller, and the conveying roller cannot contact the outer packaging material. For example, Chinese patent application number CN202311142622.3, published on December 5, 2023, discloses a printing device for producing outer packaging boxes and a method of use, which includes a processing table, and a processing device for processing the packaging box is provided on the processing table. A printing mechanism for printing is provided, wherein a carrying mechanism for carrying a packaging box is provided at the bottom of the printing mechanism, and a conveying mechanism for loading the packaging box is provided on one side of the carrying mechanism; by providing the carrying mechanism, a flip plate on the carrying mechanism can realize the flipping of the packaging box, so that the ink at the ink gathering place on the packaging box can drip into the unloading box, thereby preventing the gathered ink from moving along the surface of the packaging box and causing dirt on the printed surface, and at the same time realizing the collection of ink; a drying mechanism is used to dry the flipped packaging box, thereby improving the drying efficiency of the ink on the surface of the packaging box, facilitating the subsequent processing of the packaging box, and improving the processing efficiency of the packaging box.

[0004] If the cardboard fed into the conveyor roller is not flat, it is easy for the outer packaging material to accumulate inside the equipment, causing jamming. In addition, in order to ensure the reliability of the items transported on the conveyor belt, it is necessary to set a conveyor belt with a width not much different from the conveyor belt to ensure that the cardboard is in a horizontal state when moved to the printing mechanism. This is inconvenient for conveying cardboards of different sizes. In addition, during the conveying process of the conveyor roller, the cardboard is prone to uneven upper surface due to the vibration of the conveyor belt, thereby affecting the printing effect of the subsequent printing mechanism. In addition, during the conveying process of the conveyor belt, the cardboard is also easily affected by external dust, resulting in poor printing effect of the subsequent printing mechanism.
