Carton full-bottom printing device and printing method

Abstract

The invention provides a carton full-bottom printing device. The device comprises a machine frame, a conveying belt used for conveying a carton boxboard is arranged on the machine frame, the machine frame above the conveying belt is sequentially provided with a humidifying mechanism, a line pressing mechanism and a printing mechanism, wherein the printing mechanism is used for carrying out full-bottom printing on the carton boxboard; the line pressing mechanism comprises line pressing rollers which are symmetrically arranged, and line pressing rings are arranged on line pressing rollers, rubber rollers are installed above the line pressing rollers, and line pressing gaps for allowing the carton boxboard to pass through are reserved between the rubber rollers and the line pressing rollers;the printing mechanism comprises a printing roller which is transversely arranged above the conveying belt, a printing plate is installed on the printing roller, the length of the printing roller is larger than the width of the carton boxboard, and the length of the printing plate is equal to the width of the carton boxboard. The device has the advantages that the design is reasonable, the operation is convenient, and the line pressing is carried out by humidifying the carton boxboard, so that the carton boxboard is soft and easy to press out of the creasing marks, meanwhile, the other surfaceis kept flat, and printing is not influenced, so that full-plate non-leakage-bottom printing of the carton can be realized.

Description

technical field [0001] The invention relates to the technical field of carton printing, in particular to a carton bottom-fill printing device, and also relates to a full-bottom printing method of the carton bottom-fill printing device. Background technique [0002] At present, cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. During the production process of cartons, it is generally necessary to crimp and slot the cartons. , folding and other processes, but in the existing carton manufacturing process, the creasing line of the carton is generally an open creasing line, and there will be indentations on the surface of the carton. During printing, it is difficult for the printed ink to stay in the indentation position. Therefore, there will be a problem of being unable to print or the printing effect is not good. Therefore, after crimpi...

[0002] At present, cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. During the production process of cartons, it is generally necessary to crimp and slot the cartons. , folding and other processes, but in the existing carton manufacturing process, the creasing line of the carton is generally an open creasing line, and there will be indentations on the surface of the carton. During printing, it is difficult for the printed ink to stay in the indentation position. Therefore, there will be a problem of being unable to print or the printing effect is not good. Therefore, after crimping the carton with the existing creasing method, the carton cannot be printed on the bottom, which greatly limits the printing range of the carton and cannot meet the needs of the market. need
