In the modern production and logistics system, the efficiency and quality of product packaging directly affects the production efficiency and market competitiveness of enterprises. As the last process of packaging, box sealing is responsible for sealing and reinforcing the products after packing to ensure that they will not be scattered or damaged during transportation. The traditional manual sealing method is inefficient and inconsistent sealing effect, it is difficult to meet the needs of modern mass production. For this reason, the automatic sealing machine came into being, it can automatically complete the folding cover, sealing, tape bonding or packing and other processes, greatly improving production efficiency and packaging quality, has become an indispensable and important equipment in the packaging automation production line.

　　First, the definition and working principle of automatic sealing machine

　　1. Definition: Automatic sealing machine is a kind of automatic packaging equipment, mainly used for automatic folding, sealing and gluing of cartons filled with products. The equipment through the conveyor belt automatically into the box, and the use of robot or pneumatic device to complete the box lid folding and sealing, the whole process without manual operation. The sealing methods usually include tape sealing, hot melt adhesive sealing or packing tape sealing, which can ensure the box sealing firmly and beautifully.

　　2. Working principle - the main workflow of automatic sealing machine includes the following steps:

　　1. Carton conveying and positioning: the carton with products enters the sealing machine through the conveyor belt or roller conveyor. The inductor automatically detects the size of the carton and carries out precise positioning.

　　2. Automatic Folding: The automatic folding mechanism will fold the front cover, back cover and side cover of the carton in turn to ensure that the mouth of the carton is flat. The folding process is smooth and does not damage the carton.

　　3. Automatic sealing and gluing: The sealing machine adopts tape or hot melt adhesive to seal the box mouth automatically. The sealing tape is neatly cut, firmly and beautifully glued.

　　4. Automatic output and detection: The sealed carton is automatically output through the conveyor belt. Equipped with visual detection or weight detection device to reject the unsealed or unglued cartons to ensure the yield.

　　Second, the core advantages of automatic sealing machine

　　1. Improve production efficiency, save labor costs: automatic sealing machine can work 24 hours a day, suitable for large-scale production line. Sealing speed, efficiency up to 1530 boxes / minute, far more than manual sealing efficiency. Reduce the dependence on labor, effectively reduce labor costs.

　　2. Sealing beautiful and solid, improve packaging quality: automatic sealing machine sealing neatly, tape or hot melt adhesive bonding flat, not wrinkled, not crooked. Uniform sealing strength, will not appear loose or warped phenomenon. High consistency of sealing quality, avoiding manual operation error.

　　3. Wide range of application, compatible with a variety of carton specifications: the equipment can be adjusted to fit a variety of carton sizes by adjusting the width and height. Support the function of automatic type change to realize the rapid switching of different cartons. Suitable for multi-industry, multi-specification packaging needs.

　　4. Intelligent operation, easy to use: equipped with PLC control system and touch screen interface, easy to operate. Parameter setting and adjustment can be completed by one key, reducing manual intervention. Automatic detection of carton specifications, intelligent adjustment of sealing angle and speed.

　　5. Energy saving and environmental protection, reduce material loss: automatic sealing machine can accurately control the use of tape or hot melt adhesive, reduce waste. Reduce material loss and save cost. High sealing efficiency, help reduce energy consumption and carbon emissions.

　　Third, the application areas of automatic sealing machine

　　1. E-commerce and logistics industry: automatic sealing machine is widely used in e-commerce packaging center and logistics sorting line. Efficient sealing to improve order processing speed, to meet the needs of e-commerce platform for high-volume delivery. Ensure that the carton sealing firm, to prevent the transportation process of loose boxes.

　　2. Food and beverage industry: applied to food, beverage and dairy products and other bottled or canned products packaging sealing. Ensure the sealing of food packaging and prevent external contamination. Meet food safety standards and improve production efficiency.

　　3. Pharmaceutical and health care industry: the pharmaceutical industry has strict requirements for sealing quality and cleanliness, automatic sealing machine can ensure that the carton sealing tight. Meet the GMP production norms, to ensure the safety of drug transportation process. Automated production line to achieve unmanned sealing, improve efficiency and qualification rate.

　　4. Daily chemical and cosmetic industry: used for toiletries, detergents, cosmetics and other bottled or boxed products sealing. Ensure that the sealing is beautiful and does not affect the product packaging design. Improve production efficiency and adapt to mass production.

　　5. Electronics and hardware industry: applied to home appliances, electronic components, hardware tools and other carton packaging sealing. Firmly seal the carton, preventing it from falling apart or breaking during transportation. Realize packaging automation, reduce labor costs.

　　Fourth, the future development trend of automatic sealing machine

　　1. Intelligent and automated upgrade: the future automatic sealing machine will be integrated with AI visual inspection and automatic correction function to ensure the quality of sealing. Support automatic identification of carton size and automatic adjustment of parameters to improve the level of equipment intelligence. Connect with MES system to realize real-time tracing and monitoring of packaging data.

　　2. Multi-functional integration design: the automatic sealing machine will be integrated with automatic packing machine, labeling machine and palletizer to form an integrated packaging line. Realize the automation of sealing, packing, labeling and palletizing, and further improve the production efficiency.

　　3. High-speed and flexible production: in order to meet the demand for different specifications of cartons, the automatic sealing machine will have a rapid change function. Realize flexible packaging production, to adapt to the needs of multi-species, small batch orders. High-speed sealing machine will be used in express logistics and e-commerce warehousing areas to meet the demand for high-speed sealing.

　　4. Energy saving and environmental protection and green packaging: automatic sealing machine will use energy-saving motor and environmental protection tape to reduce energy consumption. Optimize the use of sealing materials to reduce packaging costs and waste. Meet the green manufacturing and environmental standards.

　　As an important equipment for modern packaging automation production, automatic sealing machine plays an important role in food, medicine, e-commerce logistics and other fields. It can significantly improve the sealing efficiency, ensure the consistency of sealing quality, and effectively reduce labor costs and material loss. With the development trend of intelligence, flexibility and environmental protection, automatic sealing machine will continue to upgrade to provide enterprises with more efficient and intelligent automated packaging solutions.
