[Chinese Packaging Network News] China's packaging machinery started relatively late. After more than 20 years of development, China's packaging machinery has become one of the top ten industries in the machinery industry, providing effective protection for the rapid development of China's packaging industry, and some packaging machinery has filled up. Domestic gaps have basically met the needs of the domestic market, and some products still have exports. China's export volume of packaging machinery is less than 5% of its total output value. Imports, however, are roughly equivalent to the total output value, which is far from the developed countries.
Composition of packaging machinery and equipment
Generally speaking, according to the common principles of the working principle and structural performance of packaging machinery and equipment, the composition of packaging machinery and equipment can be divided into eight parts, which are also called the eight elements of packaging organization.
(1) Packing material sorting and supply system A system in which packaging materials (including flexible, semi-rigid, rigid packaging materials and packaging containers and auxiliary materials) are cut to a fixed length or arranged and arranged and transported one by one to a predetermined station. For example, the wrapping and cutting mechanism for wrapping paper in a candy wrapper. Some canning machine's feeding system can also complete the can lid orientation, feeding and other work.
(b) The system for measuring, sorting and arranging the items to be packaged and delivered to a predetermined station for the measurement and supply system of the packaged goods. Some can also complete the setting and segmentation of packaged items. For example, a beverage filling machine metering and liquid feed system.
(c) The main transport system is a system in which packaging materials and packaging items are transported sequentially from one packing station to the next. However, single-station packaging machines do not have a transmission system.
All packaging processes are often distributed on the packaging machine to coordinate the completion of several work stations, so must be a specialized agency to send the packaging materials and packaged items until the product is exported. The formation of the main transport mechanism generally determines the form of the packaging machine and affects its appearance.
(4) The packaging implementing agency is the organization that directly completes the packaging operation, including the institutions that complete operations such as wrapping, filling, sealing, labeling, and bundling.
(5) The product output mechanism is a mechanism for removing, orienting and outputting the packaged product from the packaging machine. The final product output of some packaging machinery and equipment is completed by the main transport mechanism or is unloaded by the weight of the packaged product.
(6) Power machines and transmission systems are the prime movers of mechanical work. In modern packaging machinery and equipment, usually electric motors, there are also used combustion engines or other power machines.
(7) The control system consists of various manual devices and automatic devices. In the packaging machine, the output from the power, the operation of the transmission mechanism, the operation and cooperation of the packaging actuators, and the output of the packaged products are all manipulated by the control system instructions. It mainly includes packaging process control, packaging quality control, fault control and safety control.
In addition to mechanical forms, modern packaging machinery and equipment control methods include electric control, pneumatic control, photoelectric control, electronic control, and jet control. They can be selected based on the automation level of packaging machinery and equipment and the requirements for packaging operations.
(8) The fuselage is the part that is used to install, fix, and support all the components of the packaging machine and that can meet the mutual movement and mutual position requirements. The fuselage must have sufficient strength, stiffness, and stability.
China Packaging Network editors believe that with the continuous development of science and technology, the emergence of a variety of food processing products, put forward new requirements for packaging technology and packaging equipment, packaging machinery in the circulation area is playing an increasingly important role . The competition for packaging machinery has become increasingly fierce, and highly automated, intelligent, multi-functional, high-efficiency, and low-consumption packaging equipment have become increasingly popular in the industry.
