Description

A labeling machine for plastic cups

technical field

The invention belongs to the technical field of mechanical equipment and relates to a labeling machine for plastic cups.

Background technique

Cups are one of the most common utensils in life, used for making tea, drinking water, washing, etc., including glass materials, metal materials, ceramic materials, plastic materials, etc. Among them, the production cost of plastic cups is relatively low due to the simple manufacturing process , and not easy to break, so it is only used widely. After the production and processing of plastic cups, it is generally necessary to paste labels on the outer wall of the plastic cups to show information such as production and raw materials. At present, the labels of plastic cups are generally manually pasted, but due to the large production volume of plastic cups, through Manual labeling is not only a waste of labor, but also the quality of the label after labeling is often not high enough, and it is prone to inconsistent height, tilt or wrinkle. Therefore, in order to improve efficiency and labeling quality, machines that can automatically label workpieces have appeared on the market.

For example, Chinese invention patent application (200810186451.3) discloses a labeling machine and relates to a method of applying information to containers and/or labels by means of an inkjet printer having at least one print head, the print head having at least one nozzle, In the case of this labeling machine, the cover can be selectively moved to a position in front of the discharge opening of the nozzle so that the ink discharged from the nozzle is recirculated into the ink circuit. Therefore, it is also possible to operate the printer during pauses in printing, thus preventing the ink from drying out in the print head. However, this labeling machine performs inkjet processing on the labels that have been pasted on the workpieces, and it is difficult to directly label the workpieces.
