Packaging is a necessary condition for products to enter the circulation field, and the main means of achieving packaging is the use of packaging machinery. Packaging machine tools occupy an important part of the packaging machinery, and the excellent tool directly affects the quality of the packaging machinery. With the development of the times and the advancement of technology, packaging machinery is playing an increasingly important role in the packaging field. Its main functions are as follows: (1) can greatly improve labor productivity. Sliding plastic sealing machine mechanical packaging is much faster than manual packaging, such as candy packaging, manual sugar can only pack more than 10 pieces in 1min, and candy packaging machine can reach hundreds or even per minute. Thousands of blocks, increasing efficiency by dozens of times. (2) It can effectively guarantee the quality of packaging. According to the requirements of packaging articles, according to the requirements of the packaging materials, the packaging materials with the same specifications can be obtained, and manual packaging cannot be guaranteed. This is especially important for export goods. Only mechanical packaging can achieve standardization and standardization of packaging, and meet the requirements of collective packaging. (3) It can realize the operation that cannot be realized by manual packaging. Some packaging operations, such as vacuum packaging, pneumatic packaging, body packaging, isostatic filling, etc., are all impossible to achieve by hand packaging, and can only be realized by mechanical packaging. (4) It can reduce labor intensity and improve labor conditions. The labor intensity of manual packaging is very high. For example, it is labor-intensive and unsafe to use manual packaging of large and heavy products. For light and small products, due to high frequency, The monotonous movements make it easy for workers to get occupational diseases. Folding box machine (5) Labor protection for workers For certain products that seriously affect the health of the body, such as dusty and toxic products, irritating and radioactive products, it is inevitable to endanger the health by hand packaging, while mechanical packaging can be avoided. It can effectively protect the environment from pollution. (6) It can reduce the packaging cost and save the storage cost. For loose products, such as cotton, tobacco, silk, hemp, etc., it can be compressed and packed by compression packaging machine, which can greatly reduce the volume and reduce the packaging cost. At the same time, because the volume is greatly reduced, the storage capacity is saved, the storage cost is reduced, and transportation is facilitated. (7) It can reliably ensure the hygiene of certain products, such as the packaging of food and medicine. According to the hygiene law, it is not allowed to be packaged by hand because it will pollute the product, and the mechanical packaging avoids direct contact with food and medicine. Hygienic quality. (8) It can promote the development of related industries. Packaging machinery is a comprehensive science involving materials, processes, equipment, electronics, electrical appliances, automatic control and other disciplines. It requires the simultaneous and coordinated development of all relevant disciplines, any discipline. The problems will affect the overall performance of the packaging machine. Therefore, the development of packaging machinery will strongly promote the progress of related disciplines. In addition, in order to meet the needs of high-speed packaging of packaging machinery, its related front and rear processes are bound to adapt to it, which promotes the simultaneous development of related processes.
