Development status of packaging machinery
Still in terms of food sales packaging, there are two categories of the most commonly used and most basic packaging processes today, namely filling and wrapping. The filling method is suitable for almost all materials and various packaging containers. Specifically, for liquids, powders, and granules with good fluidity, the packaging process can be completed mainly by relying on its own gravity, and it is necessary to supplement it with a certain mechanical action. For the semi-fluid with strong viscosity or the single and assembled parts with larger body, the corresponding mandatory measures such as extrusion, push, pick and place are required. As for the wrapping method, it is different from this. It is mainly suitable for single pieces or assemblies with regular shapes, sufficient rigidity and tight packaging, and flexible plastics and their composite materials (some additional Lightweight pallets, liners), wrapped by mechanical action.
In the past ten years, the international packaging industry has attached great importance to improving the general capabilities and multi-functional integration capabilities of packaging machinery and the entire packaging system, and to provide timely and flexible production means for market development of rapidly changing products. At the same time, based on the actual needs of reasonable simplification of packaging and superior packaging process methods, continuous exploration has significantly accelerated the pace of its own technological innovation. Especially in response to the synchronous development of modern automatic machine tools, it is gradually clear. In order to establish a new system of packaging machinery with diversification, generalization and multi-function integration, we must first focus on solving the big problems of combination and mechatronics, which is undoubtedly an important development direction in the future.
Mechanical packaging has replaced manual packaging, which has greatly improved the efficiency of packaging, but the proliferation of packaging has also become a vice. In the future, not only packaging, but also packaging machinery will develop towards environmental protection. Green environmental protection is the main theme of the future.
