The fully automatic vacuum nitrogen filling can sealing machine is a new type of can sealing equipment, mainly aimed at the milk powder and health product packaging industry with high cleanliness requirements. The equipment is based on a single-head can sealing machine. After improvement, a pre-sealing five-station can sealing machine is added, which greatly improves the production speed.
This model reaches the industry level in terms of vacuum sealing quality and automation level. It fills the gap in domestic large-scale milk powder cans without high-speed sealing equipment, fully meets the needs of large and medium-sized producers, and its technology is in a world position. The entire machine adopts an integrated electronic control system to realize automatic opening of the lid, automatic entry and exit of the tank, automatic vacuum filling of nitrogen and pollution-free automatic sealing. Electrical, pneumatic and other automatic transmission components all use foreign advanced transmission elements, with a high degree of automation and stable and reliable operation. The working parameters can be easily designed and changed through the touch screen to meet the sealing requirements of different round cans.
The single-seam sealing process uses synchronous operation of the first and last sealing wheels to make the can body flange and the can lid hook edge bend in the overlapping state, and form a tight five-layer tinplate structure through compaction and sealing. The sealing wheel mainly causes the can body flange and the can lid hook edge to be fully bent and hooked in the overlapping state, and the second sealing wheel applies pressure to achieve a tight seal after the initial seal is formed. The symmetrical structure of the first and second wheels makes the sealing quality of large tanks more stable. Equipped with a vacuum system to evacuate the tank, eliminating the need for an exhaust box, which can both reduce product costs and extend the shelf life of the tank.
