Stage development 1. From the late 1980s to 1994 is the first stage. This stage is mainly to introduce and imitate the incomplete labeling machines that have been eliminated from abroad. At that time, several labeling machine manufacturers could only produce labeling machines with two labels (neck and body labels). As domestic equipment was far behind imported equipment in terms of function, performance, appearance and labeling quality, this period Imported labeling machines dominate the Chinese market, and most manufacturers still choose imported labeling machines. 2. From 1995 to 2001 is the second stage. This stage is the upgrading stage of labeling machine production in China. The first is the increase in labeling speed, from 24,000 bottles/hour to 33,000 bottles/hour, and the second is the improvement of the function of the labeling machine, from the second label (neck and body label) to the fourth label, that is, the head can be applied at the same time , Neck, body, back label. 3. From 2002 to present, it is the third stage. This stage is the mature stage of Chinese labeling machine technology and a major turning point in the history of Chinese labeling machine. In the past four years, while domestic labeling machine manufacturers have competed with each other, they have also formed a competitive situation with foreign labeling machine manufacturers. They have improved in competition, developed in improvement, innovated in development, and grown in innovation. , And gradually completed a "qualitative" leap.
