A printing mechanism of a label printing machine

Abstract

The invention discloses a printing mechanism of a label printing machine. The printing mechanism comprises a translation assembly, a code printing assembly, a transmission assembly, a stripping plate and a label pallet, wherein the translation assembly can drive the code printing assembly to move; the transmission assembly is fixedly arranged on a rack of the printing machine; the transmission assembly is located below the translation assembly and the code printing assembly; the translation assembly comprises a first air cylinder; the code printing assembly comprises a second air cylinder; the first air cylinder moves along the horizontal direction; the second air cylinder moves along the vertical direction; the stripping plate is arranged at the front end of the transmission assembly; and the label pallet is located below the transmission assembly. The code printing assembly which is vertically designed is adopted in the printing mechanism, and a label paper tape is conveyed to a code printing plate and can be further conveyed to a sticking mechanism after being subjected to code printing operation of the code printing assembly and the stripping operation of the stripping plate.

Description

[0001] Technical field: [0002] The invention relates to the technical field of printing and packaging equipment, in particular to a printing mechanism of a label printing machine. [0003] Background technique: [0004] The label printing machine is a device that pastes rolls of self-adhesive paper labels on products or specified packaging. The label printing machine is an indispensable part of the modern printing and packaging industry. At present, the peeling label in the labeling industry uses a servo motor as the power to drive the driving wheel, and then uses the driven wheel to press the label on the driving wheel. The friction force between them pulls the label, so that the label is peeled off and pasted on the product to be pasted. The application number is CN201220694548.7 A new type of labeling machine, including a frame, a conveyor belt and a labeling mechanism located above the frame and control system; the labeling mechanism includes a fixed plate, a servo motor...

The label printing machine is an indispensable part of the modern printing and packaging industry. At present, the peeling label in the labeling industry uses a servo motor as the power to drive the driving wheel, and then uses the driven wheel to press the label on the driving wheel. The friction force between them pulls the label, so that the label is peeled off and pasted on the product to be pasted. The application number is CN201220694548.7 A new type of labeling machine, including a frame, a conveyor belt and a labeling mechanism located above the frame and control system; the labeling mechanism includes a fixed plate, a servo motor, a coding mechanism, and a label tray for label winding, a tensioning shaft, multiple film guiding shafts, a peeling plate, a driving wheel, a pressure wheel and a film collecting plate in turn; There is also a detection electric eye connected to the control system above the frame. The detection electric eye is fixed on one side of the conveyor belt and is located under the peeling plate. The labeling mechanism also includes an adjustment for label winding and movement controlled by the control system to elongate the label. shaft, the adjustment shaft is set between the peeling plate and a film guide shaft close to the peeling plate, and the fixed plate is provided with a long groove for the adjustment shaft to move, but the setting of the coding mechanism of this labeling machine is not reasonable enough, it is inclined Setting, it is not easy to control when the coding component is working, and the force is small
