Multi-color label rotary printing machine

Abstract

The invention discloses a multi-color label rotary printing machine. The printing machine structurally comprises a rack, a label collecting rack, a control panel, printing chambers, drying mechanismsand a paper placing rack, wherein the label collecting rack is horizontally mounted on the right side of the rack and is mechanically connected; the control panel is vertically mounted at the upper end of the rack; the printing chambers are vertically mounted at the upper end of the rack and are mechanically connected; and the drying mechanisms are arranged among the printing chambers and are mounted at the upper end of the rack, and each drying mechanism comprises a bottom drying box, a drying channel, an air box, a connecting structure and a fan, wherein the drying channel is arranged abovethe bottom drying box, the air box is horizontally arranged above the drying channel, the bottom drying box is connected with the air box through the connecting structure, and the fan is arranged in the upper end of the air box in an embedded manner. According to the printing machine, the connecting structure is arranged between the bottom drying box and the air box, the drying speed is accelerated through double-sided drying, and meanwhile, the undried ink is adhered, so that color mixing is prevented, ghosting or pasting is also prevented, and the quality of a label is improved.

Description

technical field [0001] The invention belongs to the field of printing machines, and in particular relates to a multi-color label rotary printing machine. Background technique [0002] At present, labels are mainly used for classification and introduction of products. With the continuous improvement of production automation, productivity is also getting higher and higher, so the demand for labels used in products will also increase, and derivatives The diversification of labels has led to the development of label printing in all directions, realizing the current multi-color and automatic printing, speeding up the printing speed of multi-color labels, and meeting the productivity needs of products, but the existing technology has the following shortcomings: [0003] Due to the continuous improvement of the printing speed of the rotary printing machine, the traditional drying technology will be difficult to catch up with the printing speed, and the rotary printing machine is co...

Problems solved by technology

[0003] Due to the continuous improvement of the printing speed of the rotary printing machine, the traditional drying technology will be difficult to catch up with the printing speed, and the rotary printing machine is composed of multiple single-color printing machines, and the method of multiple single-color overlay printing is used to achieve multi-color When the printing is completed, it will touch the ink of different colors when it enters the next printing point, which will cause the label to mix colors, cause ghosting or paste, and affect the quality of the label.
