Plastic bottle labeling machine design

Abstract

With the rapid development of China's packaging industry, adhesive automatic labeling machine is more and more widely used in product labeling. With the development of automation, automatic machinery and equipment slowly began to replace manual operation, not only high efficiency and low cost, and began to be widely used in various industries, labeling machine is the product that came into being. This paper briefly describes the labeling machine, and expounds its structure and working principle, and puts forward some design ideas of labeling machine for discussion.

This paper introduces the development of plastic bottle labeling machinery and its domestic and foreign development, at the same time describes the development of plastic bottle labeling machinery and existing principles of labeling machinery, introduced some new plastic bottle labeling machinery. The linear adhesive plastic bottle labeling machine designed in this paper, the split bottle mechanism separates the plastic bottle equidistant for accurate labeling, the conveying mechanism transmits the plastic bottle to the labeling position through the plate conveyor belt, and the labeling mechanism and the rolling mechanism cooperate to complete the labeling function. In this paper, the overall structure of linear plastic bottle labeling machine is designed, and the structure of each part is designed in detail.  with analysis, calculation.
