The German government proposed the concept of "Industry 4.0" in the "Germany 2020 High-Tech Strategy", and the three themes of "smart factory", "smart production" and "smart logistics" came into being. With the advent of the industry 4.0 era. The concept of smart packaging is eager to try in the domestic market, and with technological changes, it spreads to all packaging equipment, including wrapping packaging machines.

Stretch wrapping machine uses stretch film as packaging material, which is applied to pallet packaging. It uses wrapping method to pack various regular or irregular goods, and uses the retractability and self-adhesiveness of stretch film to bind goods and pallets into a whole. It plays a fixed role and plays a role of dustproof, moisture-proof and damage-proof for the goods, especially suitable for packaging, transportation or storage of cartons, bottled goods or bulky goods.

At present, although the level of the domestic wrapping packaging machine industry has made great progress compared with before, the degree of intelligence and technology has not yet reached the level of developed countries. Compared with the United States and Japan, domestic wrapping packaging machines are reliable in terms of control technology and products. Gender differences are evident.

In order to better implement lean management, improve product operation skills, and expand work ideas, on April 25, 2023, Shandong Liyang Intelligent Equipment Co., Ltd. organized employees to go to the production workshop for training and learning.

The main content of this study includes the familiarity of equipment parameters and configuration and the mastery of the entire operation process of the equipment. On the morning of the 25th, under the leadership of General Manager Shi, a systematic visit and study was conducted to the small cylinder paper machine P500 and the online wrapping packaging machine, correspondingly learning the operation skills and on-site management of the wrapping packaging machine. Throughout the learning process, everyone studied seriously, asked for advice humbly, and showed a good spirit.

The small cylinder paper machine P500 wrapping packaging machine is mainly suitable for the packaging of cylindrical objects. The size of the goods is length * width (200-500) mm * (200-800) mm, and the load is 50-60kg. It is especially suitable for small cylinders. The closed package of the goods, such as: non-woven fabrics, coils, rubber products and the packaging of their finished products, etc., is beneficial to the storage, transportation, dustproof and moisture-proof of the goods. Cylindrical paper machine P500 can choose the size of the packaging film according to the size of the goods, 300mm or 500mm. In order to fix the goods, clips can be added on both sides of the drum paper machine, and the shafts on the clips are rolled and rotated accordingly. The film frame is fixed, but it can be manually adjusted according to the height of the goods, and the film frame can be removed to adjust the height manually. The equipment is light and handy, easy to operate and extremely efficient in packaging.

The online wrapping packaging machine adopts an integrated design, which is connected to the assembly line. The palletizing robot performs palletizing. After the palletizing is completed, a conveying signal is given. After specifying the position of the machine, the wrapping machine will automatically wrap the goods. After the wrapping is completed, the automatic film cutting device will automatically cut off the film, and then the electric soldering iron will weld the film on the goods smoothly, which is smooth and beautiful. After the packaging is completed, a conveying signal is given to convey the goods. In line with the assembly line of more high-end enterprises, it integrates the functions of automatic laminating machine and online packaging machine. It not only combines the advantages of the two equipments, but also runs more smoothly, with more perfect functions, high efficiency, simple installation and maintenance. Convenience, less space for operation.

Through this training and learning, we have benefited a lot. Everyone not only improved the employees' cognition and operation ability of products, but also broadened the ideas of on-site lean management, received a lot of inspiration and learned new methods. We will learn from each other's strengths and continue to improve, so as to improve work efficiency, enhance the company's overall image, and promote the stable, healthy and sustainable development of the company!
